3Introduction
- This unit is all about behavior.
- Behavior involves actions by organisms in
response to particular situations. - The responses may be to internal stimuli or cues
that are generated within the organism, itself,
as in an empty stomach generates hunger - An animal seeks food when it is hungry and a
hungry plant seeks sunlight as this is its
source of energy. - Actions may be in response to external cues as
well such as a response of a rabbit its detection
of a predator. - A rabbit freezes in place when it detects a
predator, but runs in a zig-zag pattern from a
predator that is pursuing it.
4- In order for an animal or any organism for that
matter to respond to internal and external cues,
it also must have the means to detect these cues.
- Organisms vary in the extent to which they
utilize vision, hearing, smell and touch in
detecting objects and events. The senses like
actions are components of behavior. - Finally, just as an organisms size, shape and
color adapts it to the environment in which it
lives, behavior is adaptive and it too is
inherited or passed on from parent to offspring. - All organisms exhibit behavior, even bacteria,
though, of course, it is most important to
animals that are able to move in complex ways.
- In this unit, you will learn the ways in which
behavioral traits contribute to the success of
individuals and the species they represent. Part
I examines the various senses and Part II
environmental influences and learning.
5Behavior
- Definition the actions or reactions of an
- organism in response to internal or
- external stimuli
- All Organisms possess morphological,physiological
and behavioral traits.
6The Student Will
- Explore the different senses.
- Explore environmental effects on behavior and the
mental capabilities of animals in solving
environmental challenges

9Part I. The Senses
- Senses provide an animal access to external
information and they also filter information from
the external environment, determining what an
animal tunes into and what it does not. - We usually think in terms of the so-called five
senses - Taste, Touch, Hearing, Vision, Smell
- There are additional senses such as
- Magnetic field, Heat, Electric senses.
- There are also many variations on any particular
kind of sense. - Variability exists because sensory systems have
developed for different functions. - Thus, different organisms sense the world in
different ways.
10Objective
- In the following exercises, have fun
experimenting with your own sensory capabilities
as well as experiencing the world from the
viewpoint of animals that have different sensory
capability
11Exercise 1 The Tactile Sense (Touch)
- While the other senses are limited to special
organs in the body such as vision with eyes,
hearing with ears, and smell with the nose, the
sense of touch (tactile sense) is located all
over the body just below the surface layer of
skin in the dermis layer. - Here thousands of sensory cells (nerve endings)
detect pressure/weight, temperature, pain and
other lesser stimuli. - Locations that are more sensitive to external
cues have concentrations of these nerve endings - Fingertips,
- Lips
- Tongue
- Your sense of touch allows you to tell the
difference between rough and smooth, soft and
hard, and wet and dry, sticky and smooth etc.
12Objective
- Exercise 1 helps students determine how well
their sense of touch works
Exercise 1.1. The Tactile Box (K-1)
Exercise 1.2. What is the Object in My Box?
Exercise 1.3. The Black Box Introduction to the
Scientific Method, Using Limited Senses
13Exercise 1.1. The Tactile Box (K-1)
State Standards Science
- Materials
- Wooden Box Cube with hole on side
- Touch Sense Chart shown below (teacher makes
copies)
141.1 Tactile Box Directions
- Divide the class into groups of 3 -4 students who
will share one of the 6 tactile boxes available
(frog on top) - WARNING! DO NOT ATTEMPT TO LOOK INSIDE THIS BOX!
- In this exercise, your sense of touch becomes
your only guide. - Your goal is to find each of five surfaces by
using only your sense of touch and . . . . . . . - One surface will feel rough or prickly.
- One surface will feel soft.
- One surface will feel smooth.
- One surface will feel sticky.
- One surface will feel bumpy.
15(Handout)
16- The teacher will give each student a copy of the
chart handout - and the students should have crayons or other
drawing tools - available to them or provided stickers of the
pictures - displayed on the next slide (also available as a
handout).
- Insert your hand into the box and attempt to feel
the inside of the surface that has the hand
printed on it. - Now run your hand along it.
- How does it feel? Soft? Bumpy? Prickly? Sticky
Smooth? - Glue a sticker corresponding to the way this
surface feels in the empty box next to the box
containing the hand sticker. - (For example, if it feels soft, the either draw a
bunny or glue a bunny picture in the box).
- Share the box with other members of your group
and see - whether every one agrees with the feel you have
chosen
17- In your chart draw or glue a picture of a
Bunny soft Knuckles bumpy
Porcupine prickly
Honey sticky
Butter smooth
18Handout stickers
19- Once everyone in your group has finished feeling
the hand wall and filling in the blank box on
their charts, give another student in the group
first chance to feel the next surface (foot
picture). - Repeat this process until all empty boxes are
filled. - Check your results with other groups in your
class. - Finally, confirm your results by looking at the
answer chart on the next slide.

22Exercise 1.2. What is the Object in My Box?
State Standards Science
- Your teacher has a number of objects that can be
found in the clear box marked Teacher (Black
Box) Crayon, paper clip, rubber ball, metal
ball, tooth pick, cotton ball, rubber band,
marble, penny, poker chip and a cork. - She/he will place a different object in each of
the tactile boxes available to you. - Put your hand through the hole and find the
object. Without pulling out to look at it, feel
it, hold it in your hand and make a guess as to
what it is.
23- Now pull it out and look at it. Did you guess
right? - The teacher will replace the objects with new
ones until the entire class has had a chance to
complete the test.
- Your teacher can also hand you an item behind
your - back to do this exercise.
- Repeat the game, only this time your teacher will
show you all of the possible objects that might
be given to you before you feel the mystery
object. - Was this second version of the game easier for
you? If so, why do you think that is true.
24Exercise 1.3. The Black Box Introduction to the
Scientific Method, Using Limited Senses
State Science Standards
- Scientific inquiry involves obtaining insight
into something that is unknown to you. - It is a stepwise process that involves
observation, hypothesis formation and testing. - The goal of this exercise is to rely on your
senses in applying the scientific method to
obtain as much information as you can about each
of the two unknown objects that are in a
solid-covered tin marked as 'Do not open'. - To assist you in this endeavor, the metal
container with transparent lid found with this
unit has a series of objects from which the two
mystery objects have been selected a toothpick,
crayon, paper clip, rubber ball, metal ball,
cotton ball, rubber band, marble, penny, poker
chip and a cork.
25- ONE RULE NO PEAKING INTO THE BLACK BOX (solid
tin cover) BEFORE you commit your results to
paper or announce them to your class. - Split into small groups (4or so) that will
collaborate in this study. - Find the two bags marked Black Box Experiment.
Each groups of students should have in front of
you a round tin with clear lid marked as 'White
Box', a magnet and a flat tin with solid cover
marked as 'Black Box'. This second container has
a 'Do not open sticker' on it as well. - Examine the series of objects forming the
contents of the White Box, listing them on a
sheet of paper or on the board so that you may
consult the list as your investigation proceeds. - Follow the chart shown (fig. 1) in pursuing the
identity of each of the two objects in your black
box.
26Fig. 1 Process to follow in determining which two
items are in the Black Box
'START HERE'
27- There are 2 routes you might take in solving this
puzzle - You might start by placing one known object at a
time in the white box tin and recording its
characteristics on a piece of paper. - You could then hypothesize as to what
characteristics you would sense for a particular
object if it were in the black box, testing for
and rejecting each item on the list. - Alternatively
- You might first examine the black box tin for
weight, sounds and other characteristics you
might detect. - Then you would hypothesize what two objects are
in the box and what sounds, weights etc each
conveys. - You would test the known objects in the white box
corresponding to your hypothesis, rejecting it if
the characteristics do not match.
28- At the end, present
- a list of the characteristics that you have
surmised for each of the two mystery items, - your techniques for arriving at each
characteristic, and - your hypothesis as to what each object might be
to your teacher for class discussion. - Now open the black box and check to see if you
were correct.
29Exercise 2. The Chemical Senses Smell/Olfaction
- Almost all animals use the chemical senses, taste
and smell, to some extent. - The chemical sense involves the detection of
molecules as each gives off a unique odor. - Just as related frogs have similar songs,
materials that are composed of similar molecules
have similar smells and tastes. - To aquatic and burrowing animals, the chemical
sense is the prominent one. - On the other hand, most birds have a very poor
sense of smell rather, they rely on their keen
eyesight. - Our chemical sense is crude compared to that of
man's best friend the dog. We can't deal with
taste in our exercises, but the sense of smell,
itself, has a wide variety of uses.
30- In social communication, individuals produce
odors called pheromones that attract others to
them. Individuals might also release chemical
signals that tell others to stay away. - For example, male wolves, foxes and dogs mark
their territories with urine it repels other
males. - Some animals also release chemical signals when
they are frightened and this warns other
individuals to seek cover or run away. - The following two exercises explore this sense
using the human nose.
31Objective
- Exercise 2 allows students to use their nose to
hypothesis what organism is linked to an odor.
Exercise 2.1 How good is your nose? (K-12)
Exercise 2.2 Find that Flower I (K-12)
322.1 How good is your nose? (K-12)
State Science Standards
- How good is your nose? Not as good a your dog.
- That is for sure.
- In this exercise you will be exposed to a series
of odors, and will be asked to identify them
without seeing the source of the smell. - The odors are present in two levels of
difficulty coarse level discrimination and fine
level discrimination.
332.1a Coarse Level Discrimination
- The goal of this exercise is to identify the
sources of different odors. - Locate the cardboard shoebox with the nose
sticker on it. - Station each of the 6 bottles at different points
in the room. - Each student should number a sheet of paper from
A1 to A6. - As a student visits a station, he or she should
write the name of the object that he/she thinks
produced the odor on the line that corresponds to
the (station number) on the lid of the jar at
that station. DO NOT LOOK AT THE BOTTOM OF THE
JAR - The teacher will poll the class for their
decisions for each odor source.
Now, lets see how you did

- A 5. Blue 5 Coffee A 6. Blue 6 Licorice
36If you did not do so well, remember that humans
do not have a well-developed sense of smell.
- Repeat the above exercise after examining the
pictures and object list available under Answers
for Exercise 2.1a - Did you do better choosing among odors than
trying to decide what an odor was without having
the list of potential odor sources beforehand?
372.1b Fine Level Discrimination
- Find the 6 red jars.
- Follow the protocol used under 2.1a above to
identify the type of fruit present in each jar.

- Red 3. pear Red 4. banana
- Red 5. orange Red 6. lemon
402.2 Find that Flower I (K-12)
State Science Standards
- Insects and flowers have a close tie to one
another. - Because flowers are stationary, many rely on
insects for pollination insects carry pollen
from the anther (male part) of one plant to the
carpal (female part) of another, permitting the
plants to produce fertile seeds.
41- In return, the plants produce nectar to attract
and feed the - insects that serve this delivery function for
them. - Insects have sensory organs to locate flowers,
they have wings - to get them to flowers that might be widely
spaced, and they - remember nectar rewards.
- Thus a given insect tends to focus on the same
species of flower - in a foraging bout, and this increases the
chance that flowers - will successfully produce seed sets.
42- It is actually very important to the plants that
an insect visits only flowers of the same species
when it is foraging from one plant to another or
all that nectar and pollen the individual plants
have produced would go to waste. Thus different
insects are attracted to the characteristic odors
particular plant types' produce. - This exercise is a class activity that explores
the flower selection process of three insect
types a bee, a fly and a butterfly.
43Directions
- Within the cardboard shoebox with the nose
sticker, find the three dark green bottles, a
blindfold and a set of deely-boppers. - The class should line up in two columns of
individuals facing one another with sufficient
space between the columns for an insect (member
of the class) to walk through. - Find a volunteer to serve as a foraging bee.
Place the deely-boppers on her/his head as well
as the blindfold. - Find the jar marked 'bee' and identify a student
in one of the columns that will serve as the
target flower. Be careful not to reveal where
this target flower is to the blindfolded
individual. The target will hold the jar at neck
height in front.
44- The blind-folded insect is instructed to walk
down the space between the 2 columns to find the
target flower by the scent it emits. - Recap the lid and place back in the nose box.
- Stop! Bee result discussed next
- Bees are attracted to what humans would call
sweet or spicy scents. Because we can detect
these scents and they register as pleasant to us,
many perfumes are similar in scent to the flowers
bees are attracted to. We refer to these perfumes
as floral in nature as the person wearing one
smells a bit like a florist shop - Repeat the above steps with the fly scent.
Stop! Fly result discussed next
45- Flies unlike bees are attracted to odors that are
not very pleasant to humans. As they lay their
eggs (oviposit) on rotting flesh and dung, plants
that emit similar odors attract them. - Repeat the protocol for the butterfly jar.
- Stop! Fly result discussed next
- Butterflies and birds are not very olfactory.
They are much more visual in behavior. Thus, your
butterfly did not do very well in locating the
target flower. That is, unless this particular
student volunteer serving as a butterfly had an
unusually acute sensitivity to the odor emitted
by a cotton ball!
46Exercise 3. Visual Sense (Vision)
- Touch and smell provide important information to
animals about their environments and the
activities of other animals in them. - However, these senses are limited to simple
messages. -
- In the more complex animals, two vibrational
senses, sight and hearing, are utilized
prominently in communication among individuals
and both in detecting prey and avoiding
predators. - Most animals are sensitive to light in one manner
or another. - Vision involves the sensitivity of different
organisms to vibrational energy within a narrow
band of very short wavelengths.
47Objective
- In this series of exercises you will explore its
function in foraging, in the avoidance of
predation, and in social communication.
Exercise 3.1 Find that Flower II (3-12)
Exercise 3.2 Slap Snack Alarm (K-2) and
Slap-Snack Mimic (3-12)
Exercise 3.3 Jumping Spider Dances
48Exercise 3.1 Find that Flower II (3-12)
State Science Standards
49- Under the sense of smell exercises you learned
that some insects (e.g., bees and flies) locate
flowers by the particular odors they give off to
advertise their available nectar supplies. - Bees also use the visual sense to locate nectar
sources though they are not as restricted to
vision as are the butterflies.
- The parts of a flower and its color have evolved
to attract particular insects. - For instance, there are few green flowers,
because flowers need to present a target
(bulls-eye) to potential pollinators. - Different species are sensitive to different
color patterns and many insects view the world
through the ultraviolet wavelengths. - The pictures on the next page show what we see
versus what the bee sees through its ultraviolet
filter.
50(No Transcript)
51Objective
- The following competitive experiment will provide
you with first hand experience on the extent to
which flowers are designed to attract animal
pollinators.
52Directions
- Find the cardboard shoebox with the flower on the
lid. - Locate four volunteers from the class.
- Designate two of these individuals as flower
holders (flowers wave in the breeze). - The tube behind each flower should have some
nectar in it (a few red puff balls). (If these
are missing, add a few from the packet in the bag
holding the flowers.) - The other two individuals will serve as insects.
Each will place a straw in his or her mouth and
should clasp right and left hands behind the back
so they will not be tempted to use them. - Assign one insect to a particular flower and the
other to the remaining flower.
53- Each pair of flower and insect individuals should
face one another such that the flower tube is
visible to the rest of the class. - At the count of three, each insect should attempt
to get its beak (straw) down into the nectar tube
of its flower as it waves in the breeze. - The object is to drag some nectar (a puff ball)
up the tube towards the flower head. No need to
take the ball out of the tube just bring it up
to flower head. - The first insect to do this, WINS.
- Repeat with a few pairs of individuals.
- Was one flower more often associated with the
winner? Why might that be?
54Time to check your answers Exercise 3.1
55- One of the flowers has a funnel that guides the
insect's proboscis (straw) to the nectar source
the other lacks the funnel. - Most flowers have not only petals shaped in a
funnel but also nectar guides, lines or color
patterns that radiate out from the source of the
nectar reward. - The anthers will be located above the funnel or
below the legs of the insect standing on the
landing platform such that pollen will stick to
the legs for transport to other flowers of the
same species. - See pictures on next slide.

57Exercise 3.2 Slap Snack Alarm (K-2) and
Slap-Snack Mimic (3-12)
- Unless an animal is at the top of its food chain,
it faces the problem of predation where other
animals prey/feed on it). - Because of their small size, insects are a major
prey source to mammals and birds and they have
developed two mechanisms - of avoiding predation.
- 1. Many plant feeding insects incorporate the
noxious chemicals plants produce as defense
mechanisms into their own tissues. This makes
these insects taste bad and many are even
poisonous to eat. - 2. Other insects have developed venoms that are
released from specialized hairs and stingers on
their bodies or mouthparts. Anyone who has
encountered the saddleback caterpillar or a
yellow jacket wasp understands the repelling
effect stings can have on a predator thinking
about attacking a particular prey.
58- Both poisons and venoms are chemical defenses
against predation. - The value of the defense to a particular prey,
however, is limited as it might be injured or
swallowed by the attacking predator before the
chemical defense is released. - Thus insects and other animals that have chemical
defenses also tend to be brightly colored. - These prey are taking advantage of the fact that
mammals and birds have the ability to learn - 1. Through experience with a distasteful or
stinging insect that is brightly colored a
predator tends to avoid similarly colored
organisms in the future. - 2. Nearby mammals and birds may learn from
watching another animals response to a noxious
prey. - The common colors used as warning or aposomatic
colors are red as in a stop sign, yellow or a
blend of the two, orange.
59- Just as red and yellow warning signs attract our
attention when we are driving down the road and
everyone recognizes a Tennessee fan in school
colors, red, yellow and orange attract the
attention of predators. - A young bird or mammal may well eat one or two
brightly colored insects, but it quickly learns
to avoid insects that have red or orange or
yellow patches as being bad. - In the following exercises, you will be predators
making decisions about what prey to eat. - The wrinkle is that you will be competing with
your classmates to obtain limited food as there
is not enough to share.
603.2a Slap Snack Alarm (K-12)
State Science Standards
- In this exercise, you pretend that you are hungry
birds looking for something to eat. - Say three of you are searching an area together
as birds commonly do.
61Slap Snack Alarm continued
- As you encounter a potential prey item, you need
to very quickly decide whether to attack it or
not. - If you are too slow in your response, the prey
may escape or another bird might get it first.
The problem is that not all prey are good
prey. You have to be careful not to grab
something that will poison you or cause you pain
or even death.

63Directions
- Divide the class into groups of 4 students.
- Each group should have a deck of cards
- One student should serve as the dealer and the
other three as birds. - The dealer will turn one card over placing it in
the center of the desktop. The first person to
slap that card with his or her hand gets the prey
item and moves it to his/her pile. - If no bird attacks a given card, the dealer moves
it to a no eat or discard pile next to the
original deck. - Continue the foraging bout by offering all cards
in the deck one at a time for potential
predation. - At the end, each individual should check the prey
in his/her pile for noxious (bad tasting) and
venomous prey - (frownie faces on key next slide)
64(No Transcript)
65- Remove one good tasting prey type for every sad
face prey item in your deck. - The number you are left with is your food reward
score. - Which member of your group was the best
forager---had the highest food reward score? - Also, the larger the no eat pile is at the end of
the game, the better your group is at being
'smart' predators. - Be sure to put all of the cards back in the box
when you are finished and to return this box and
the answer sheet packet to the wooden trunk.
66Exercise 3.2b. Slap Snack Mimic
- Because the majority of bad tasting and venomous
insects are brightly colored and escape
predation, other insects cheat by producing
similar bright color patterns.
67Slap Snack Mimic continued
- This is called mimicry in which a species lacking
chemical - defenses mimics a model species present in the
same habitat that - has chemical defenses.
- The advantage to the mimic is that the predator
may have previously experienced a capture attempt
with the model species and has learned to avoid
the type. - In this second exercise, you will be foraging
birds feeding that are competing for food. - You will be required to make a quick decision as
to whether an insect is palatable (tasty) or not
(chemical defenses present).
68- The object is to receive the greatest foraging
reward. - You will receive 2 points for taking a prey that
is neither a model or a mimic, and 5 pts for
taking a mimic. However you will suffer (lose -10
pts) for taking a model (chemically defended)
prey item. - Before starting
- 1. Examine some examples of models and mimics on
the next few slides. - 2. Examine the slide that distinguishes the
hymenopterans (bees, ants and wasps) from other
types of insects and even spiders that mimic
them.

78Directions
- Split into groups of 4 students sitting around a
cleared desk. - Examine
- the mimicry sheets that will be displayed at the
front of the room and - the figure that shows the traits that differ
between the hymenoptera (bees, ants, wasps) and
the other insect types and spiders that mimic
them - Assign one individual as a dealer. The others
will be birds in the foraging group. - The dealer should have a score sheet with the
names of all birds on it. - Take a deck either mimic 1 or 2 and note this on
the score sheet.
79- The dealer will turn one card over placing it in
the center of the desktop. - The first person to slap that card with his or
her hand, gets the prey item. - The bird having captured a prey should check the
score on the back of the card - Place red rectangle sheet that came with card
deck over oval patch to see fitness reward or
penalty - The dealer will write this score down under that
individual's name on the group's foraging score
sheet.
Possible scores for a particular prey are 2, 5
and -10 where 2 is the reward for taking a prey
that is not a mimic or a model, 5 is the reward
for taking a mimic, and -10 is the penalty for
taking a harmful or distasteful model prey.
- Make sure that all players in the group get to
see the reward - and prey item each individual receives at each
catch so that they - too can learn from the experience.
80- If no bird attacks a given card, the dealer moves
it to a 'no eat' or discard pile next to the
original deck. - The dealer then continues the foraging bout by
offering another card in the deck for potential
predation until all cards have been offered. - At the end, the dealer will add up all of the
scores. - The bird with the highest total score is the
smartest and/swiftest predator in the group (has
the highest fitness reward).
- You might have a playoff against other winners
from the class.
81- Have a class discussion concerning the
differences in outcomes between mimic decks 1 and
2.
Stop! The answer is next.
- Mimicry works best only if the model is more
abundant than the mimic (deck Mimic 1). - If there are more mimics than models present
(deck Mimic 2), the predators are more likely to
encounter a tasteful mimic than a model and will
keep this prey type in its diet. - For a population of largely mimics, the predator
gets away with taking prey that exhibit warning
coloration.
82Exercise 3.3 Jumping Spider Dances
State Science Standards
- The two senses used in complex communication are
vision and hearing. Vision is particularly
important in male courtship of females. - Species specific color patterns and the complex
movements used to display them help prevent
wasted matings between species. - Thus biologists use courtship sequences to
identify species relationships. - Females also choose among courting males of the
same species on the basis of the quality of
displays they offer. Lizards, birds and fish are
perhaps best known for these colorful courtship
sequences.
83Lyrebird
Unicorn Tang
Mandarin
Mandarin Fish
Iguana
84- One would not expect spiders to have elaborate
visual - courtship sequences as they generally have very
poor vision and - thus are not very colorful.
- The exceptions can be found in members of the
jumping spider family Salticidae. - Males have bright color bands and patches on the
body and legs that are displayed in elaborate
dances. - Dr. Wayne Maddison and his students have been
examining species relationships within the genus
Habronattus, in part through examination of male
dances. - In the two exercises offered here, you will use
video clips of male jumping spiders to 1st
develop an ethogram and then to compare ethograms
between two species.
85- An ethogram is a quantitative description of the
natural behavior of an animal species. - We will limit the ethogram here to the behavior
of males directed towards females---the dances
they exhibit.
86Exercise 3.3.a Learn a Spider Dance (K-2)
Develop an Ethogram (3-12).
- Locate the Unit 10. CD or DVD with the Frog on
it. Find Exercise 3.3 Jumping Spider Dances. - Play each of the 8 dances through a couple of
times and choose which one you would like to
learn the dance/develop an ethogram for. - The species are Habronattus americanus
(american), H. tarsalis (foot) H. Tuberculatus
(knobby), H. coecatus (lacking color), H.
jucundus (merry), H. decorus (elegant), H.
altanus (alta high altitude), and H.
carolinensis (carolina). (Note that some of the
dances are quite long and thus are split into 3
clips in order from start to finish). - Play the clip of the chosen species again
counting the number of actions that occur in the
dance.
87- Make a list of numbers on a sheet of paper
corresponding to the total number of acts you
counted in the dance. (Make a master list on the
board.) - Play the clip again concentrating on the 1st
action seen. Each student should write a
description of this action pattern under 1 on
the list of numbers. - Discuss the action among you and come up with a
name that best describes it. Use this name
whenever you see this action again during the
course of the dance. This will eliminate the need
to write down the description each time. - Repeat these steps until all of the different
actions have been defined and assigned a name.
88- Now view the sequence of events from beginning to
end, writing down the actions in the order that
they occur.
You may need to repeat the clip a number if times
to get all number slots filled.
- Once your list is complete, you can perform the
dance and describe the behavior in terms of an
ethogram. - Are there repeated patterns, just as in the
chorus of a song? - Are some behavior patterns more frequent at the
beginning of the sequence and replaced by others
later etc.
89Exercise 3.3b. Comparing Ethograms.
- The goal of this exercise is to compare the
dances exhibited by different species - Identify species that are more closely related to
one another based on the actions they perform.
90Directions
- Assign each species to teams of 3-4 students.
- Each team will complete an ethogram for their
species, which they will share with other groups. - Using the set of ethograms, each team should then
cluster species together in groups that have the
most elements (action patterns) in common. - Develop a branching diagram of your choosing that
reflects the relationships among the different
species.
Two Branching Patterns
91- Compare the species relationship tree you have
developed to that developed for these same
species using molecular sequence data.
Stop! Answer is next
92- Do species that are most closely related in
their genetic make-up share more behavior
patterns in common than more distantly related
species? - Are there qualitative (e.g., apples vs oranges)
differences among the species (different behavior
patterns). - Perhaps the differences are merely quantitative
ones (same behavior patterns but relative
frequencies as in same behavior pattern
emphasized in one species and not used much in
another)? - You can calculate act relative frequency by
dividing the total number of acts of a given type
(i), sum Ai, by the total number of acts observed
in the sequence, sum An, and multiply this result
by 100 - Rel Freq 100(SumAi/sum An)
93Exercise 4. Hearing is a Vibrational Sense
- Many organisms have hair sensory cells
- that detect air or fluid movement.
- Terrestrial (land dwelling) vertebrates have
these hair sensory cells concentrated in two
ears, one on either side of the head. - Thus, we say that vertebrates with ears 'hear'
sounds. - In the vertebrate ear, sound waves hitting the
ear cause movement of the fluid in a chamber
housing the sensory hair cells. - The movement of the fluid causes the fine hairs
to bend and receptors in each hair cell send this
information on for processing. - As it is difficult to see at night, nocturnal
animals communicate mainly by sound and their
sense of hearing is well developed.
Em picture
94Objective
- Exercise 4 teaches students how different species
uses their vibrational senses to hear and
communicate with each other.

Reading Sonograms (6-12)
954.1. Bat Echolocation
State Science Standards
96Bat Echolocation continued
- Bats use high sound pitches
- that are at the upper limit of
- human hearing.
- They actually produce ultrasonic calls that they
send out into the night air in search of flying
insects. - When these sound waves hit a flying object, the
signal bounces back just as a ball you have
thrown at a wall comes back towards you. - Receptors in the bats ears are tuned to
screening the ultrasonic playbacks to detect
potential prey and repeated calling permits the
foraging bat to locate these prey.
97Directions
- Choose an individual who will be the bat in this
exercise. This person should put on the blindfold
that can be found in the shoebox with the nose
sticker on it. - Five additional students should be selected as
moths, the favored prey of bats. - In a place free of furniture and other objects
that our bat might trip on, the rest of the class
should form a circle around the bat and moths. - The goal of the exercise is for the bat to locate
all of the moths by echolocation.
98- The bat does this by calling out 'BAT'.
- The moths must reply each time they hear the word
bat by - calling out 'MOTH'.
- The bat needs to move towards the call of the
nearest moth. - The moth is captured if the bat touches it with
his/her hand. - At this point, the moth has to exit the circle.
- You might time this exercise to see if some
students are better than others in using
echolocation. - Be sure to place the blindfold back in the
appropriate box at the end of this exercise.
99Exercise 4.2 The vibration sense of spiders
- Like bats, spiders use the sense of hearing
though the spiders located ears are on its legs
the term vibrational sense is used rather than
hearing that is restricted to animals with ears.
State Science Standards
- Some of the sensory hair cells are located in
the joints of the legs where they detect cahnges
in leg position.
100- As a spider sits on its web, an insect hitting
the web causes the - silk strands to move which in turn causes the
spiders foot - and leg to move.
- These sensory hairs in the leg joints are
disturbed by the leg movement and send the
vibratory information on for processing. - As in bats, a spiders hair cells are tuned to
particular vibration patterns. - Information on the type and size of insect
hitting the web is obtained through this sense. - Most spiders can see no more than a couple of
centimeters distant (there are 2.54 cm/1 inch).
Thus, the vibration sense is its main sense.
101Directions
- Divide the class into groups of 6 individuals.
Each group should take a clear plastic box with
the spider web sticker on it. - One person in each group will be the spider and
the other five, insects. - First unwind the fishing lines wrapped around the
wooden block in the box with the spider on it as
the designated spider - holds it.
- Each designated insects should then take one of
the monofilament lines and move away from the
spider. - The spider will then position his/her free hand
on the top of the wood block such that one finger
is resting on each of the five lines, radiating
out to the insects.
102- Place the blindfold over the eyes of the spider
- Check that each of the insects backs up until all
lines are taut. - The teacher or some selected student should tap
one of the insects, who will pluck his/her
thread. - When the spider detects the pluck, it should pull
on this line. Did the spider find the correct
prey? - Switch off with different individuals serving as
spider and insects.
103Exercise 4.3. What kind of Frog is it? You can
tell from calls males make. (3-12)
State Science Standards
- Animals use the vibration sense to detect prey
and to avoid predators. - They also communicate through the production of
sounds and the processing of these sounds. - Like birds, male frogs and toads sing to attract
females to them.
104- It is important to both sexes that they locate
only individuals of the same type or species, so
each species has a unique song or call. - However, the calls of closely related species are
more similar to one another than are other frog
or toad calls. - In Tennessee, we have three major groups of
frogs - the 'true' frogs,
- the 'toads',
- the 'tree' frogs (see figures on the next
slides). - In this exercise, you will learn the differences
in calls among the three major frog groups and
will then be asked to assign the calls that you
hear to the correct group.

109Exercise 4.4. Frog call patterns put to paper
Reading Sonograms (6-12)
- It is easy enough to listen to songs made by
various frog and toad species and detect
differences among them. - Biologists, however, need to be able to measure
the differences (quantify them) and determine the
extent to which these calls vary.
110(No Transcript)
111- We cannot simply take out a ruler and measure the
differences in calls as we might do say with the
length of a leg or the height on an individual. - Nor can we take out a color chart and assign a
color shade to it as we might do for eye or skin
color. - One of the most basic techniques biologists use
to analyze non-visual traits is to present the
information graphically, a form that can be
measured visually. - Sounds can be converted to sound spectrograms or
sonograms in which they are laid out in two
dimensions (time and frequency or pitch) as shown
on the following graph of the chickadee's song.
112Objective
- In this exercise, you will learn how to read
sonograms. Your challenge in the end will be to
identify the sonogram that belongs to each of the
mystery calls made by various true frog, tree
frog and toad species.
113- Find the CD for Unit 10 with the frog picture on
it and open track 4 for an introduction to
Exercise 4.4 Frog Sonograms - Follow along with the sonograms shown below as
instructions are given to you under track 5. - After you learn about the translation of songs
into graphs, you will be able to place each call
with its graphical representation.

121Part II. Environment and Learning
- Behavior like morphological traits such as size
and coloration and physiological traits such as
heart rate and the mechanics underlying sensory
perception is inherited (passed on from parents
to offspring through genes). - Behavior differs from the other traits though in
the extent to which it can be modified by
environmental influences. - Behavior shows a much higher level of plasticity
or flexibility and this reflects learning and
mental processing. - Remember that when we refer to the environment of
an animal, we mean both physical features such as
temperature and wind, but also biotic features
such as prey, predators and even other members of
the same species.
122Objective
- The exercises in this section of Unit 10 Behavior
explore environmental effects on behavior and the
mental capabilities of animals in solving
environmental challenges.
Exercise 5. Temperature Influences Call Rates
Exercise 6. Animal Choice The T maze
Exercise 7. Caching acorns a memory game
123Exercise 5. Temperature Influences Call Rates
(3-12)
- Ectotherms (ecto outside, therm temperature)
such as toads and crickets do not have an
internal mechanism of controlling their body
temperatures. - Thus the body temperature of a frog in the water
is the same as that of the water and the body
temperature of a cricket and a frog sitting near
a pond are the same as air temperature. - Male frogs and crickets use muscle actions to
produce their calls. - Because muscles work faster and more smoothly at
warmer temperatures, one might expect that on
cold nights, some aspect of the call such as its
rate of repetition might be decreased over the
pattern exhibited on warm nights. - Where environments have this influence, females
processing the male calls would either have to
correct for air temperature (do the math) or
their processing of the calls would have to be
temperature-dependent as well.
124Objective
- In this exercise you will calculate the effect
temperature has on frog and cricket songs. -

Exercise 5.1 Temperature and Frog Call Rates
Exercise 5.2 Temperature and Cricket Call Rates
125Exercise 5.1. Temperature and Frog Call Rates
(3-12)
- Frogs produce sounds by forcing air through the
larynx (the upper end of a windpipe that contains
vocal chords). - The air vibrates the vocal chords and a special
vocal sac is blown up like a balloon to amplify
the sound (make it louder). - What instrument does this remind you of?
Stop! Answer next
A Scottish bagpipe
126Directions
- Find out how temperature affects call songs by
finding Exercise 5.1. on the Unit 10 Behavior CD
(frog pictures) starting with an introduction on
track 8 - You will need a piece of paper, a pencil and a
ruler to complete this exercise. - Listen to the instructions to the exercise on
track 9. - Complete the exercise presented on tracks 10-22.
127Exercise 5.2. Temperature and Cricket Call Rates
- The male cricket song consists of a series of
chirps. - The chirp is produced by a process similar to
that of a person playing a violin. - The wing moves over a comb-like structure (bow
over strings) that is positioned on a sound-box
filled with air. - The sound box amplifies the sound (makes it much
louder).
128Directions
- You will need a piece of paper, a pencil and a
ruler to complete this exercise. - Find the Unit 10 Behavior CD with the calling
frog pictured on it. - Go to track 23 for introduction to temperature
effects on calls. - Go to track 24 to listen to a cricket call
- Play tracks 25 - 38 for the activities associated
with Exercise 5.2. At the end, you will be able
to tell air temperature from the number of chirps
a cricket makes in its call in a 10 sec interval.
129Exercise 6. Animal Choice The T maze
Science Math
State Standard
- When we mention the word maze, everyone thinks
of the maze puzzles or perhaps the garden
challenge you visited one day where you start at
one end and try to find the exit at the other
(see figures on next slides).
130Animal Choice The T maze continued
- Animal behaviorists use these mazes to test the
learning and memory capabilities of animals as
well as for preferences. - There will be a food reward at the end of a
simple maze and mice, rats and other test
subjects will be released many times in the maze
to see if they make fewer wrong turns with
successive tries as well as reach the reward more
quickly.
131- The T-maze available to you in this exercise is
commonly used in experiments to test for animal
preferences. It is called a T-maze because it is
shaped like a T with the animal starting at the
base of the letter and making a choice with a
left or right turn at the top arms.
132- What kinds of questions can you answer with a
T-maze? - Sidedness. Does the animal prefer to go to the
left or to the right arm or does it visit arms in
a particular pattern? Perhaps it goes to
alternate arms on successive trials. - Simple Learning. If you place a reward in one
arm, how many trials will it take for the animal
to go directly to the arm offering the reward? - How many runs will it take for it to forget that
a reward was offered only in a particular arm,
once the reward has been removed. - Finally, can you re-establish the preference by
bringing the reward back. Will the animal learn
more quickly this second time?
133- Preference. The most common use of the T-maze is
to check for preference, asking an animal to
choose between two options. - Suggested rewards for the maze you have are
- shade vs light,
- moist substrate vs dry
- odor vs none
- substrate color
- substrate texture
- food
- no food
- Consult figure (next slide) that describes the
scientific method. - Also, remember that testing one individual does
not make a scientific study. You can pool the six
animals tested in the class if every one is doing
the same experiment, or each group of students
could test multiple animals.
134(No Transcript)
135Objective
- In this exercise you will be designing your own
hypotheses and protocols that will test them.
136Directions
- Find the zippered plastic bag marked as Exercise
6. Take out the 6 mazes and assign 1 to every 4
students. - Note the size of the track. You will need to find
test subjects that will be able to walk down this
groove (e.g., sow, pill or potato bugs
(crustaceans), ants, spiders, small beetles, meal
worms, small crickets.) - Wash the track with a paper towel with soapy
water. - Decide what question you want to ask.
- Obtain all necessary materials for completion of
the trials. - You will probably want to wash the track between
each trial to ensure that odor trails left by the
individual in one run do not influence its
behavior in later runs.
137Exercise 7. Caching acorns a memory game
Science Math
State Standards
- Animals frequently face the problem of feast and
famine.
138Caching acorns a memory game continued
- That is, there are periods when food is so
abundant that individuals could not possibly eat
more than a small fraction of what is available
to them ('The Feast'). - And then there may be extended periods when food
is scarce ('The Famine'). - Quite a few animals solve this problem by storing
food items for future use. This behavior is
called caching (pro-nounced cashing). - Birds and squirrels are examples of animals that
cache food.
139Multiple seed caches 3 birds
Beaver single cache
- Sometimes there is a central cache that is, the
animal stores all of its food in a single place. - This is not a particularly good strategy,
however, as competitors might find the location
and steal the food reserves. - Thus, individuals of most caching species have
numerous caches, sometimes as many as a hundred,
scattered throughout its home range.
140- Problem 1. If the animal puts all food collected
in the same place, other animals may find and
steal the lot. - Problem 2. If the animal puts the collected food
in many different places, how does the animal
find its food again? -
- How do animals find their food caches again?
Three tactics might be taken. - 1. Episodic Memory. The animal memorizes where it
has stashed the contents of each foraging bout it
makes. It remembers the episode just as you might
remember a particular birthday party. - 2. Re-foraging the Home Range. No memory is
involved in this tactic. The animal merely
re-searches the entire home range when looking
for a meal during periods of famine. - 3. Rule-based Search. In utilizing this tactic,
the individual follows certain rules in locating
its caches. For instance, it might place food
items only under rocks or on the west side of
trees. In rule-based search, the animal only
needs to remember the rule.
141Directions
- This is a game for three or four (squirrels)
students using the same foraging area (matt on
desk). - One squirrel is the individual who will cache
acorns around its home range. - The cheating squirrels will have a chance to find
the caches and steal the acorns before the owner
gets a chance to retrieve them. - If all of the acorns are not found, then the
trees in the wood
