Lecture #4: Climate Change

Question 1

What are some ways species respond to climate change in terms of phenology?

Answer 1

1) timing of development (ex: hatching)
2) sensitive to environmental cues (ex: warm–> mating)
3) determining envriomental conditions + biotic interactions

Question 2

range shifts

Answer 2

species shift to stay with their ideal range towards poles, up in elevation

Question 3

why are alpine tundra species at risk

Answer 3

they do not have anywhere further to move up to a cooler region

Question 4

what prevents ability of species to shift with climate

Answer 4

1) physical barrier
2) competition with species present
3) mutualists not present in new range
