What type of habitat will allow species to cope with a change in environment?
Heterogenous habitats- differing micro-habitats species can move between
What 3 physiological measurements can help us to predict the future of rising global temperatures?
1) Body temp
2) Resting metabolic rate
3) Water loss
What are 3 possible responses to a change in environmental temperature?
1) Spatial distribution
2) Temporal distribution (timing of biological events)
3) Phenotypic change
Do endotherms or ectotherms have wider thermal tolerance ranges?
Endotherms
What is a performance optimum?
Where no energy is needed to keep at optimum temp where performance is highest
What organism may benefit from a change in environmental temperature?
An organism that isnt living in an environment at its thermal optimum
What does a thermal performance curve show?
The range of temperatures under which an organism is able to survive
What are the consequences of the changing environments?
- Organisms lack appropriate physiological adaption for new environmental conditions
Why are oceans becoming more acidic?
Because C02 levels are rising
