... was compared between temperatures and developmental stages. The effect of cold acclimation on the cardiac proteome was only evident in the context of an interaction with life stage, suggesting that ontogenic differences in anoxia tolerance may be predicated on successful maturation of the heart. The main...

This causes lower incubation temperature in more challenging conditions, with consequences for a range of offspring traits. It is not yet clear how low developmental temperature affects cold...

That thermal sensitivity changes with progression through embryo development, but not larval development, thus points to a key dependence on complexity in terms of cell division, but not growth, in early life. Thermal sensitivity in G. caespitosa clearly depends on developmental changes other than size...
