25Intergovernmental Panel on Climate Change IPCC
Established by U.N. Environment Programme and
World Meteorological Union.Composed of thousands
of atmospheric scientists and climate scientists
throughout the world who review literature,
evaluate what is happening, and provide
consensussummaries.
- AR-4 Fourth Assessment Report Feb 2007
- Warming of the climate system is unequivocal
- Most of the observed increase in globally
averaged temperatures since the mid 20th century
is very likely due to the observed increase in
anthropogenic greenhouse gas concentrations.
- Very likely gt 90
26Intergovernmental Panel on Climate Change IPCC
- The understanding of anthropogenic warming and
cooling influences on climate has improved since
the Third Assessment Report TAR 2001 leading to
very high confidence that the globally averaged
net effect of human activities since 1750 has
been one of warming, with a radiative forcing of
1.6 (range 0.6 2.4) - very high confidence gt 90

are familiar - ??????

44Crop Production Climate
- Just like natural biomes, crops are grown under
optimal climatic conditions temperature
precipitation. - Rule of Thumbeach 10C temp. increase ? 10 crop
yield reduction. - Crops cannot just move north.
- Corn currently grows in Iowa, wheat in Kansas,
- Not only because of ideal climate which can
move north, - but also
- because of ideal soils and photoperiod which
cannot move north. - Corn is a water intensive crop.

46How Do Organisms Respond to Climatic Temperature
Increases?
- Temperature Relationships
- Ectotherms obtain heat from environment.
- Endotherms generate their own heat from
metabolic processes.
47Ectotherms cold-blooded creatures are
temperature dependent.
Ambient temp,body temp, and metabolic
rate relationships of a typicalEctotherm.
48The Consequence, for example..
Cabbage white caterpillar, Pieris
rapae,development is temperaturedependent.
49Cabbage white caterpillar, Pieris
rapae, requires 174day degrees above
10.5oC. At 11.5oC takes 174 days At 12.5oC
takes 87 days
50Consequences
As planet warms they move
And to HigherElevations
51For plant development the same principles apply
growth rate is temperature dependent
But, for plants and animals rather thanaverage
temperature, seasonal extremes may be more
important.
52SaguaroCereus giganteus -Northern limit
of distribution is where a day without
thawing occurs. Can withstand a night of
freezing,but must thaw next day.

55Range Expansion
Africanized honeybeesWhen conditions
areappropriate, species expand their ranges -
at a rate allowedby the mobility of their
dispersal phases.

61Bark beetle damage
Millions of acres in Alaska and B.C.The insect
was previously slowed by cold winters.
- In addition,
- Drought stresses trees
- But tree stress response often involves
- an increased free amino acid pool in cells
- ?making foliage more nutritious
- enhances insect development rate
- exacerbates outbreak

64What About the Future?
Tree species are limited by climatic conditions
A common tree here now but MO may no longer
be in range
65As the optimum range of tree species is adjusted,
so is that for other spp., biotic communities,
and forestry and agricultural systems.
66Biome Climate Shifts
Climatic optimum forall will shiftNorth but
soilswill stay where they are. If biomes move
N,so will fauna.

71Increased CO2 is Beneficial?
- A Skeptic Argument
- Plants use CO2 in photosynthesis.
- Animals produce CO2 in respiration.
- Increased CO2 must be beneficial to plants.
- Indian agricultural productivity has increased.
- See any problems???
- 1 and 2 are typical half truths
- Plants both photosynthesize respire
- Naïvely assumes CO2 is limiting factor in all
plant growth. - Assumes all plant species in a community will
increase the same, i.e. no competitive
differences exist amongst them. - But increased temperature decreases crop yield.
- Is Indian increase due to CO2? Why accept this?
Reich, PB, Hungate BA, Luo Y 2006. Annual Review
of Ecology Systematics. 37 611-636.
72Von Liebigs Law of the Minimum Plant growth
is limited by the critical factor that Is in
shortest supply. In fact in most cases, soil
nutrients Nitrogen (N), Phosphorous (P),
Potassium (K),
CO2 enrichment affects annual plant communities
both in terms of productivity and species
composition The effect of CO2 on such systems
may depend upon other resources such as light
and nutrients. Zangerl and Bazzaz 1984
Oecologia 62 (3) 412 417.
Plant species that seem to respond best are early
successional species (disturbed area invaders),
spp we call weeds. So consequence may be
.more herbicides.

81Do Endotherms Respond?
- Ectotherms generally fluctuate with external
temperatures - But
- Endotherms generate their own heat.
- Are they climate dependent?

- Long-distance migrants appear less likely to
alter migration timing, but food is available
much earlier - Migrants often respond to photoperiod but
- Insect food at nesting location responds to
day-degrees.so food surge is earlier and
precedes nesting.

131As the temperature across the U.S. has gotten
warmer, the purple finch has been spending its
winters more than 400 miles farther north than it
used to.
The National Audubon Society report based on the
Christmas bird annual count indicates that half
of 305 selected bird species in North America --
a sample that includes robins, gulls, owls and
other common species -- are on average spending
winter about 35 miles farther north than they did
40 years ago.

139HerpetofaunaGeneral patterns of response
- Range shifts
- Changes in developmental phenology
- Behavioral or morphological changes
- Shifts in genetic frequencies

Missouri, Columbia
140Meta-analyses
- Parmesan and Yohe 2003
- Range limit shifts
- 6.1 km/decade polewards or 1m/decade upwards
- Birds, butterflies, alpine herbs (99 species)
- Phenology shifts
- Development advance of 2.3 days earlier/decade
- Herbs, shrubs, trees, birds, butterflies,
amphibians (172 species) - Root et al. 2003
- 143 species
- 80 of species with change show shifts in
expected direction

141Amphibians
Reptiles
- Desiccate easily
- Shell-less eggs laid in water or damp places
- Many depend on ephemeral wetlands
- Resist desiccation
- Eggs with leathery shell to reduce water loss
- For some, sex of offspring depends on incubation
temperature

Missouri, Columbia
142Breeding phenology
- Warming trend since 1900 correlated with earlier
anuran calling in NY (Gibbs and Breisch 2001) - British amphibians breeding earlier over past 17
years (Beebee 1995) - But pattern not universal (Blaustein et al. 2001)

143Wetland hydroperiod
- Importance of temporary waters
- Intermediate hydroperiods best
- Early drying may result in zero recruitment

Missouri, Columbia
144Temperature-dependentsex determination
- Sex ratios of turtles can be highly correlated
with air temperatures (Janzen 1994) - Most nests produce a single sex
- Eggs gt 30oC ? females lt 30oC ? males
- Behavioral or physiological compensation?
- Nest site selection and phenology (Doody et al.
2006, Ewert et al. 2005) - Change in pivotal temperatures (Ewert et al.
2005, but not Doody et al. 2006)

145Additional factors
Climate change
Decreased female body condition and length
Reduced pond depth
Increased exposure to UV-B
Reduced egg production
Increased susceptibility to disease
Increased female mortality
Amphibian declines

148Past, Present and Future?
http//earthtrends.wri.org/updates/node/245
From Stephanie Long,BI489, Fall 2008
149So what?
- Marine Calcifiers (create shell or skeleton out
of calcium carbonate) - Mollusks
- Crustaceans
- Reef-forming Corals
- Some Algae
- Some Phytoplankton
From Stephanie Long,BI489, Fall 2008
150Obstacles for Marine Calcifiers - 1
- Calcium Carbonate Needed for skeletons or shells.
- Carbonic Acid releases Hydrogen ions (bad)
- -Carbonate Ion binds with Hydrogen ? becomes
unavailable. - Shell-building organisms can not use this ion for
synthesis
Krill
From Stephanie Long,BI489, Fall 2008
151Obstacles for Marine Calcifiers - 2
Critical in many food chains
- Shells that have managed to form are now more
likely to dissolve under low pH. - Lower waters naturally more acidic
- Saturation Horizon expected to rise
From Stephanie Long,BI489, Fall 2008
152Acidosis
Obstacles for Marine Calcifiers - 3
- Acidosis build-up of carbonic acid in body
fluids - Disrupts growth, respiration, reproduction.
- Affects Fish, squid, and countless other organisms
From Stephanie Long,BI489, Fall 2008
153Loss of Habitat
- Many Marine Calcifiers provide shelter for other
oceanic organisms.

158Coral Growth factors
- Nutrients
- Salinity
- Irradiance
- Turbidity
- Sedimentation
- Temperature
- pH
- Calcium Carbonate Saturation
Like swamps in rivers coral reefs are oceanic
nurseries.
