Learning Goals for Biodiversity Unit

• We are / will be learning to
• Analyse the risks and benefits of human
  intervention (e.g. pesticide use, fish stocking,
  tree planting, etc.)
• Analyse how climate change could impact the
  diversity of living things (e.g. Global warming,
  increase in precipitation)
• Become familiar with terms such as species
  diversity, structural diversity, bacteria, fungi,
  binomial nomenclature, morphology
• Classify, apply, and draw dichotomous keys to
  identify and classify organisms according to
  kingdom
• Explain concepts of taxonomic rank such as genus,
  species and taxon
• Compare/contrast characteristics of prokaryotes,
  eukaryotes and viruses
• Compare/contrast anatomical and physiological
  characteristics of organisms representative of
  each kingdom
• Explain structural and functional changes of
  organisms as they have evolved over time
• Explain why biodiversity is important for
  maintaining viable ecosystems

A Quick Recap From Yesterday

• Biodiversity The variety and number of a species
  in an ecosystem. It can refer to the variation
  between individuals within a species.
• Biodiversity within an ecosystem can be affected
  by a number of factors (e.g. invasive species,
  resource abundance, competition between species
  and within a species, reproduction, disease,
  etc.)

Calculating Diversity The Shannon Index

•  

Number of individuals of species i
Total number of species
You will need a scientific calculator for this.
Number of species
Relative abundance of species

Counting Cars Lab

• This lab involves going outside to count cars,
  determine the diversity of the types and numbers
  of different vehicle makes (NOT models)and to
  calculate the diversity found. You will be asked
  to predict, hypothesize, calculate, and
  communicate those results.
• Please note This is not a formal lab write up
  however, it will be marked. Be sure to
• 1. complete the pre-lab questions, 2. fill in the
  tables, 3. complete the calculations to determine
  the diversity and 4. answer the questions in full
  sentences.

LAB SAFETY

• We will be going outside, so please remember
  safety
• Do not leave the grounds of the school
• Stay within the group you have been assigned
• Use extreme caution in the parking lot when
  moving around vehicles and be watchful for
  vehicles moving.
• Use common sense wear a coat!
• If in doubt about anything, ask us!

Wrap Up!

• Exit Card
• Imagine that a new insecticide has been used in a
  garden that has mistakenly killed many of the
  bees that are able to visit this garden. What
  are some of the implications that this could have
  on the diversity of plants living in the garden?
  Explain.
