Evolutionary physiological ecology
Evolutionary physiological ecology. Optimum efficiencies of energy transformation in anoxic metabolism. INTRODUCTION The existence of Variation at the gene ievel is now accepted to be ubiquitous among species, although the extent of Variation is known to differ neutral theory of molecular evolution (Kimura, 1983) which assumes that the dominant forces underlying the dynamics of gene frequency c...
متن کاملPhysiological ecology meets climate change
In this article, we pointed out that understanding the physiology of differential climate change effects on organisms is one of the many urgent challenges faced in ecology and evolutionary biology. We explore how physiological ecology can contribute to a holistic view of climate change impacts on organisms and ecosystems and their evolutionary responses. We suggest that theoretical and experime...
متن کاملStress Genes: Role in Physiological Ecology
The purpose of this article is to provide an introductory overview of stress-gene transcription in archaea for those unfamiliar with the topic. Archaea are diverse and inhabit disparate ecosystems (very cold or hot, temperate, etc.). The study of their stress genes should reveal a variety of strategies for cell survival and suggest manifold applications. Survival relies on the mechanisms of tra...
متن کاملStress Genes: Role in Physiological Ecology
Hydrothermal environments contain steep thermal gradients and variable temperature conditions. Hyperthermophilic microorganisms, those which grow at temperatures exceeding 90°C, are common in these environments and have numerous means for tolerating hyperthermal stress. All hyperthermophiles examined produce a heteromeric chaperonin complex which is the primary protein produced during heat shoc...
متن کاملPhysiological ecology of overwintering in hatchling turtles.
Temperate species of turtles hatch from eggs in late summer. The hatchlings of some species leave their natal nest to hibernate elsewhere on land or under water, whereas others usually remain inside the nest until spring; thus, post-hatching behavior strongly influences the hibernation ecology and physiology of this age class. Little is known about the habitats of and environmental conditions a...
