From a new paper published in Ecology Letters, this graphic shows examples of how interactions between temperature and sexual selection drive the co-adaptation of thermal physiology, thermoregulation and sexually selected traits in animals such as lions, elephant seals, antelopes, cicadas, Japanese beetles and rose-bellied lizards.

温度は、動物の日常生活のほぼすべての部分に影響を与えます。新しい論文では、求愛行動、装飾的な色彩、角や爪のような大型の武器など、熱生物学と性淘汰が好む形質がどのように共存しているかが考察されている。
研究者たちは、動物たちが、交尾のときだけ遭遇する危険な気温に耐えることができるメカニズムも進化させてきたという証拠を広く発見したのである。

Abstract

Thermal ecology and mate competition are both pervasive features of ecological adaptation. A surge of recent work has uncovered the diversity of ways in which temperature affects mating interactions and sexual selection. However, the potential for thermal biology and reproductive ecology to evolve together as organisms adapt to their thermal environment has been underappreciated. Here, we develop a series of hypotheses regarding (1) not only how thermal ecology affects mating system dynamics, but also how mating dynamics can generate selection on thermal traits; and (2) how the thermal consequences of mate competition favour the reciprocal co-adaptation of thermal biology and sexual traits. We discuss our hypotheses in the context of both pre-copulatory and post-copulatory processes. We also call for future work integrating experimental and phylogenetic comparative approaches to understand evolutionary feedbacks between thermal ecology and sexual selection. Overall, studying reciprocal feedbacks between thermal ecology and sexual selection may be necessary to understand how organisms have adapted to the environments of the past and could persist in the environments of the future.
