-
How do terrestrial species distributions typically shift on mountains as global temperatures rise?
- To flatter valleys
- To coastal regions
- To higher altitudes
- To lower altitudes
-
What is the main ecological consequence if breeding timing changes due to global warming?
- Food supply mismatch
- Increased genetic drift
- Decreased mutation rate
- Habitat fragmentation
-
Which type of data best demonstrates whether rising temperatures cause a population decline?
- Abundance over time
- DNA sequence similarity
- Enzyme optimum temperature

-
How do climate change impacts typically compare across different plant species?
- They are negligible
- They vary widely
- They are strictly linear
- They are identical
-
Why are species with high dispersal abilities less vulnerable to climate change?
- They require less water
- They hibernate longer
- They track habitats
- They reproduce slower
-
What does it mean if a species becomes phenologically out of step with its environment?
- Altered genetic code
- Increased body size
- Mismatched seasonal timing
- Shifted geographical origin
-
Which factor acts as a major barrier to climate-driven species range shifts?
- Urban development

- Population size declines
-
How does climate change primarily disrupt existing interspecific interactions within ecosystems?
- Uncoupling species timing
- Stopping cellular respiration
