“…Production of this new, potentially infertile or lethal genotype is expected to reduce fitness in sex-reversed heterogametic individuals. By contrast, sex reversal may be neutral or even advantageous in the homogametic sex 25,27,28 . Furthermore, sex-antagonistic genes 29 accumulating on the Y or W chromosome may also cause disadvantage in sex-reversed XY or ZW individuals.…”

Sex is a fundamental trait of all sexually reproducing organisms, and sex-determination systems show a great diversity across the tree of life. A growing body of evidence shows that genotypic and temperature-dependent sex determination (GSD and TSD, respectively) can coexist, which theoretically can have wide-ranging consequences for demography and population persistence, especially under climate change. Temperature-induced sex reversal, resulting from combined effects of sex chromosomes and environmental temperatures on sexual development, can explain the frequent transitions between GSD and TSD, and even between different GSD systems, that happened multiple times in ectothermic vertebrates. However, general lack of empirical data on the prevalence of sex reversal has long constrained the assessment of its evolutionary-ecological significance. Here we analysed an exhaustive compilation of available data to demonstrate that the climatic distribution of extant species is explained by the combination of their sex-chromosome system (GSD) and temperature reaction norm (TSD) across the phylogeny of amphibians and some reptiles. This pattern is in accordance with predictions of the 'asymmetrical sex reversal' theory, underscoring the importance of temperature-induced sex reversal in phylogeography, evolution, and species conservation under the threat of climate change, and highlighting the need for more empirical research on sex reversal in nature.

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 living world is a fundamental challenge in biology. To further the development of a more reliable and holistic picture of the causes of this variation, we review several examples of how various intrinsic (biological) and extrinsic (environmental) factors (including body size, cell size, activity level, temperature, predation and other diverse genetic, cellular, morphological, physiological, behavioural and ecological influences) can interactively affect metabolic rate in synergistic or antagonistic ways. Most of the interactive effects that have been documented involve body size, temperature or both, but future research may reveal additional ‘hub factors’. Our review highlights the complex, intimate inter-relationships between physiology and ecology, knowledge of which can shed light on various problems in both disciplines, including variation in physiological adaptations, life histories, ecological niches and various organism-environment interactions in ecosystems. We also discuss theoretical and practical implications of interactive effects on metabolic rate and provide suggestions for future research, including holistic system analyses at various hierarchical levels of organization that focus on interactive proximate (functional) and ultimate (evolutionary) causal networks. This article is part of the theme issue ‘The evolutionary significance of variation in metabolic rates’.
