Variation in sperm performance and mitochondrial metabolism of Mytilus spp. from the North and Baltic Seas under different environmental scenarios
ABSTRACTClimate change, including seawater warming and salinity fluctuations, is increasingly affecting marine ecosystems worldwide. The blue mussel, Mytilus edulis, widely distributed along the temperate coasts of the Northern Hemisphere, thrives...

Links between mitochondrial function, whole-animal metabolic rate, telomere dynamics and swimming performance in minnows
ABSTRACTThe majority of fish swim by aerobic muscular force, and so there has been considerable interest in the metabolic basis for swimming. Most of this work has measured whole-body oxygen consumption as a metabolic proxy, without any quantifica...

Oxidation and allocation of nectar amino acids during butterfly flight
ABSTRACTFlying animals face extreme energetic demands, relying mainly on carbohydrates and lipids, with occasional contributions from proteins and amino acids. In nectar-feeding species such as butterflies and hummingbirds, sugars are the primary ...

Further integrating social context into comparative and environmental physiology
ABSTRACTEnvironmental factors such as temperature and oxygen are well-established modulators of animal physiology, but the influence of social context remains under-integrated into comparative and environmental physiology. Although numerous studie...

How complex must shape data be to model in vivo forces? Intraspecific level validation of in silico jaw strength estimates in a lizard
ABSTRACTA major problem in current biomechanical literature is the extent to which in silico data can be validated by in vivo data across taxonomic scales. Despite frequent incongruence between in silico and in vivo data gained from precisely the ...
