Understanding metabolic performance limitations is key to explaining the past, present and future of life. We investigated whether heat tolerance in actively flying Drosophila melanogaster is modified by individual differences in cell size ...

Metabolism energizes all biological processes, and its tempo may importantly influence the ecological success and evolutionary fitness of organisms. Therefore, understanding the broad variation in metabolic rate that exists across the livin...
Intergenerational plasticity aligns with temperature-dependent selection on offspring metabolic rates [0.03%]
代际可塑性与后代代谢率的温度依赖性选择相一致

Metabolic rates are linked to key life-history traits that are thought to set the pace of life and affect fitness, yet the role that parents may have in shaping the metabolism of their offspring to enhance survival remains unclear. Here, we...
Among-individual variation in thermal plasticity of fish metabolic rates causes profound variation in temperature-specific trait repeatability, but does not co-vary with behavioural plasticity [0.03%]
鱼代谢率的个体间热可塑性变异导致特定温度下的性状重复性的显著变异，但与行为可塑性无共变关系

Conspecifics of the same age and size differ consistently in the pace with which they expend energy. This among-individual variation in metabolic rate is thought to influence behavioural variation, since differences in energy requirements s...

The metabolism and hypoxia tolerance of marine ectotherms play key roles in limiting species geographical ranges, but underlying traits have only been directly measured for a small fraction of biodiversity. Here we diagnose and analyse spat...
Tissue-specific metabolic enzyme levels covary with whole-animal metabolic rates and life-history loci via epistatic effects [0.03%]
组织特异性代谢酶水平通过上位效应与整体动物的代谢率和生命史基因座共变
Jenni M Prokkola,Kuan Kiat Chew,Katja Anttila et al.
Jenni M Prokkola et al.
Metabolic rates, including standard (SMR) and maximum (MMR) metabolic rate have often been linked with life-history strategies. Variation in context- and tissue-level metabolism underlying SMR and MMR may thus provide a physiological basis ...
Evolutionary relationships between metabolism and behaviour require genetic correlations [0.03%]
新陈代谢和行为之间的进化关系需要基因相关性
Amélie Crespel,Jan Lindström,Kathryn R Elmer et al.
Amélie Crespel et al.
As selection acts on multivariate phenotypes, the evolution of traits within populations not only depends on the genetic basis of each trait, but also on the genetic relationships among traits. As metabolic rate is often related to vital tr...

The allometric scaling of metabolic rate and what drives it are major questions in biology with a long history. Since the metabolic rate at any level of biological organization is an emergent property of its lower-level constituents, it is ...
Temperature and nutrition do not interact to shape the evolution of metabolic rate [0.03%]

Metabolic cold adaptation, or Krogh's rule, is the controversial hypothesis that predicts a monotonically negative relationship between metabolic rate and environmental temperature for ectotherms living along thermal clines measured at a co...
