Lecture 11 - Adapting to climate change Flashcards
How have UK birds changed in phenology over the past 57 years?
The bird UK laying date is related to temperature or rainfall for 31 of 36 bird species. Generally things advance further.
How have first appearances of butterfly species changed?
They’ve reduced over time, as has the length of their appearance.
Why is early arrival useful for species?
Because it allows exploitation of favourable climates earlier in the year and early access to the best nest sites & abundant food leads to improved survival of young.
What are the downsides of early arrival of species?
Basically more at risk for extreme events, can K.O. a population. Also there may be a temporal mismatch between species and their food etc.
How have butterfly species shifted in the UK over the years?
They’ve shifted more Northern and chosen higher altitudes as temperatures rose.
What is microhabitat buffering?
Microhabitats refer to fine scale features in a habitat, they act as thermal buffers allowing species to exist under harsh conditions.
What happens to frog arboreality as temperature and moisture increases?
It reduces, as temperature and moisture gradients are steeper at the tree level than elevation level.
