2. Content:
• Biological Factor
• Biological factors of climate change
• Conclusion

3. Biological Factors:
• Anything which affects the function and behavior of a living
organism.
• The climate change effect the biological factor which have
significance importance on food chain.

4. Introduction:
• Climate change impacts the biological systems.
• Its disrupt the match between organisms and their
local environment.
• Reducing survival and reproduction.
• Causing subsequent impacts on populations or
species' distributions across geographic regions

6. Climate and Communities, Ecosystems:
• Climate change can mostly effects to the community and
ecosystem.
• Many of specie can migrate to other areas.
• Many of biodiversity are effected due to climate change.

7. Evolutionary and Morphological Changes:
• The factor often downplayed to discussion response to global warming.
• Morphological changes= changes in structure
Example: Abeille
• Europe the fly has longer wings on northern countries than in southern
countries
• Wings length shorter in southern California,
• Species can responds quickly to local climate conditions.

8. Abeille

9. Changing capacity of individual:
• Not all species able to cope with climate change conditions
• Changing climate might change the capacity of individuals.
Example: Ground Squirrel
• During aestivation period the squirrel live the summer period on
under ground.
• Due to temperature changes the summer time period incrasing.
• These animals have do not enough resources

11. Effects on Bird Species:
• Geographical ranges of species changed due to climate factors
• Analysis of the geographic range of 59 species of Great Britain birds showed
a migration in north.
• Averaging18.9km in the duration of only 20 years.
Example: Black Throated Blue Warber
• 49% (30 species) northern areas are Highly Vulnerable as the climate warms.
• Blue warber are also effected due to climate change.

13. Effects on Plant Species:
• Plant physiology is also sensitive to temperature range and moisture balance
Temperature and moisture interact to determine the rate of photosynthesis.
• Climate change effects the rate of photosynthesis.
• Season when plants lack the necessary moisture for photosynthesis or when
temperatures drop below the freezing point of water
Example: Alpine Plant
• Alpine associated with mountain peaks.
• Climate change effects the alpine plant.

15. Climate and populations:
• A population consists of a collection of individuals.
• Population size changes due to reproduction, immigration, mortality and
emigration.
• As such, a population can only grow when reproduction and or immigration is
greater than mortality and or emigration.
• Decreases when the opposite occurs.
• Due to climate population doesn’t survive.
• Lack of resources, Disease, Temperature Changes they migrate others areas.

16. Conclusion:
• Its understandable that climate change also effects the biological community.
• It is clear from both ancient and recent climate change that while some species
will adapt to new climate conditions, not all species will have the ability to
respond to changes in climate.
• Extinctions will occur; current communities of species may disassemble as
species respond differently to rapid climate change.
