identifying 'winner and losers' : which organisms are most vulnerable to warming? Flashcards
why do we need to identify potential winners and losers?
-Predicting shifts in distribution pattens
-focus conservation efforts
-identify where extinctions are likely to occur
-identify whether ecosystems are likely to maintain functionality despite shifts in species or population composition
What does higher environmental temperature lead in in terms of thermal tolerance?
Higher environmental temperature results in higher thermal tolerance, but also reduced Thermal Safety margins
Can thermal tolerance be modified through acclimation?
The most well-adapted congeners of porcelain crabs (tropical and temperature high shore) are disadvantaged by possessing a relatively small ability to increase thermal tolerance during acclimation
Describe a tropical species’ thermal performance windows/climatic niches
Narrower thermal performance windows than their temperate counterparts
Thermal safety margins (TSMs)
The difference between a species’ maximum tolerance to heat and the temperature is experienced in its environment
