lecture 15 - adapting to climate change Flashcards
1
Q
definition of thermal tolerance
A
the entire temperature range that permits survival of a species
2
Q
definition of phenology
A
the timing of seasonal activities of animals and plants e.g. arrival of migrants, breeding
phenology strongly matches climate
3
Q
benefits of change in phenology
A
- exploit favourable climates earlier in the year
- early access to best nest sites and abundant food
- potential to make more breeding attempts
4
Q
costs of change in phenology
A
- sudden bad weather can kill young or adults
- temporal mismatch with food
5
Q
how have species shifted their distribution in response to climate?
A
- moved to higher latitudes
- moved to higher altitudes e.g. 102 moth species moved upwards by average of 67m
6
Q
definition of a microhabitat
A
fine scale (cm to m) features within a habitat e.g. leaf litter, tree holes * can act as thermal buffers
