Can physiological engineering/programming increase multi-generational thermal tolerance to extreme temperature events?

Abstract

Organisms increasingly encounter higher frequencies of extreme weather events as a consequence of global climate change. Currently, few strategies are available to mitigate climate change effects on animals arising from acute extreme high-temperature events. We tested the capacity of physiological engineering to influence the intra- and multi-generational upper thermal tolerance capacity of a model organism, Artemia, subjected to extreme high temperatures. Enhancement of specific physiological regulators during development could affect thermal tolerance or life-history attributes affecting subsequent fitness. Using experimental Artemia populations, we exposed F0 individuals to one of four tr..
