Temperature as a modulator of sexual selection

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Journal Year: 2020, Volume and Issue: 95(6), P. 1607 - 1629

Published: July 20, 2020

A central question in ecology and evolution is to understand why sexual selection varies so much strength across taxa; it has long been known that ecological factors are crucial this. Temperature a particularly salient abiotic factor modulates wide range of physiological, morphological behavioural traits, impacting individuals populations at global taxonomic scale. Furthermore, temperature exhibits substantial temporal variation (e.g. daily, seasonally inter-seasonally), hence for most species the wild will regularly unfold dynamic thermal environment. Unfortunately, studies have far almost completely neglected role as modulator selection. Here, we outline main pathways through which can affect intensity form (i.e. mechanisms) selection, via: (i) direct effects on secondary traits preferences trait variance, opportunity trait-fitness covariance), (ii) indirect key mating parameters, sex-specific reproductive costs/benefits, trade-offs, demography correlated factors. Building upon this framework, show that, by focusing exclusively first-order environmental linked with individual fitness population viability, current warming may be ignoring eco-evolutionary feedbacks mediated Finally, tested general prediction conducting meta-analysis available experimentally manipulating reporting variance male/female success and/or under Our results clear association between measures both sexes. In short, suggest studying feedback processes vital developing better understanding nature, its consequences viability response change warming).

Sex-specific ornament evolution is a consistent feature of climatic adaptation across space and time in dragonflies

Proceedings of the National Academy of Sciences, Journal Year: 2021, Volume and Issue: 118(28)

Adaptation to different climates fuels the origins and maintenance of biodiversity. Detailing how organisms optimize fitness for their local is therefore an essential goal in biology. Although we increasingly understand survival-related traits evolve as adapt climatic conditions, it unclear whether also that coordinate mating between sexes. Here, show dragonflies consistently warmer across space time by evolving less male melanin ornamentation-a mating-related trait absorbs solar radiation heats individuals above ambient temperatures. Continent-wide macroevolutionary analyses reveal species inhabiting ornamentation. Community-science observations 10 indicate populations parts species' ranges through microevolution smaller ornaments. Observations from 2005 2019 detail contemporary selective pressures oppose ornaments years; our climate-warming projections predict further decreases 2070. Conversely, female ornamentation responds idiosyncratically temperature time, indicating sexes ways meet demands climate. Overall, these macro- microevolutionary findings demonstrate predictably climate just they do traits.

A comprehensive overview of the effects of urbanisation on sexual selection and sexual traits

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Journal Year: 2022, Volume and Issue: 97(4), P. 1325 - 1345

Published: March 9, 2022

ABSTRACT Urbanisation can affect mating opportunities and thereby alter inter‐ intra‐sexual selection pressures on sexual traits. Biotic abiotic urban conditions influence an individual's success in pre‐ post‐copulatory mating, for example through impacts mate attraction preference, fertilisation success, resource competition or rival interactions. Divergent lead to differences behavioural, physiological, morphological life‐history traits between non‐urban populations, ultimately driving adaptation speciation. Most studies interactions report populations correlations factors associated with increased urbanisation, such as pollution, food availability risk of predation parasitism. Here we review the literature relation urbanisation urban‐associated conditions. We provide extensive list biotic that processes involved interactions, signal production transmission, choice opportunities. discuss all relevant data lens two, non‐mutually exclusive theories selection, namely indicator sensory models.

Phenotypic selection in natural populations: what have we learned in 40 years?

Evolution, Journal Year: 2023, Volume and Issue: 77(7), P. 1493 - 1504

In 1983, Russell Lande and Stevan Arnold published "The measurement of selection on correlated characters," which became a highly influential citation classic in evolutionary biology. This paper stimulated cottage industry field studies natural sexual nature resulted several large-scale meta-analyses, statistical developments, method papers. The tools they suggested contributed to breakdown the traditional dichotomy between ecological time scales later developments such as "eco-evolutionary dynamics". However, regression-based analyses also criticized from philosophical, methodological, viewpoints some still ongoing debates about causality Here I return this landmark by Arnold, analyze controversies it gave rise discuss past, present, future populations. A remaining legacy & 1983 is that inheritance can fruitfully be decoupled studied separately, since acts phenotypes regardless their genetic basis, hence responses are distinct processes.

Understanding the evolution of ecological sex differences: Integrating character displacement and the Darwin-Bateman paradigm

Evolution Letters, Journal Year: 2019, Volume and Issue: 3(5), P. 434 - 447

Published: Aug. 26, 2019

Abstract Sex differences in selection arise for at least two possible reasons: (1) originating from anisogamy—the Darwin-Bateman paradigm—and (2) competition-driven ecological character displacement (ECD), agnostic of anisogamy. Despite mounting evidence ECD and increasing focus on the causes consequences sexual dimorphism, progress understanding evolution sex has likely been hindered because dimorphisms are not exclusive to ECD. I argue that embracing nonexclusivity causal models dimorphism itself may provide insight into differences. This integrated view leads four predictions how sex-specific phenotypic divergence between sexes change over course dimorphism. First, resulting directly anisogamy precedes driven by Second, (initially) evolve directions trait space favored other sources selection. Third, we expect correlated forms Finally, optima be specific even when competition plays a role reaching them. Rather than simply less-parsimonious alternative explanation differences, should seen as one contributor could act predictable times during dimorphisms.

Responses of intended and unintended receivers to a novel sexual signal suggest clandestine communication

Nature Communications, Journal Year: 2021, Volume and Issue: 12(1)

Published: Feb. 4, 2021

Abstract Inadvertent cues can be refined into signals through coevolution between signalers and receivers, yet the earliest steps in this process remain elusive. In Hawaiian populations of Pacific field cricket, a new morph producing novel incredibly variable song (purring) has spread across islands. Here we characterize current sexual natural selection landscape acting on signal by (1) determining fitness advantages purring attraction to mates protection from prominent deadly enemy, (2) testing alternative hypotheses about strength form signal. studies, female crickets respond positively purrs, but eavesdropping parasitoid flies do not, suggesting may allow private communication among crickets. Contrary sensory bias preference for novelty hypotheses, functions (selective pressure) are nearly flat, driven extreme inter-individual variation function shape. Our study offers rare empirical test roles stages evolution.

Male harm offsets the demographic benefits of good genes

Proceedings of the National Academy of Sciences, Journal Year: 2023, Volume and Issue: 120(10)

Published: March 2, 2023

Sexual conflict can arise when males evolve traits that improve their mating success but in doing so harm females. By reducing female fitness, male diminish offspring production a population and even drive extinction. Current theory on is based the assumption an individual’s phenotype solely determined by its genotype. But expression of most sexually selected also influenced variation biological condition (condition-dependent expression), such individuals better express more extreme phenotypes. Here, we developed demographically explicit models sexual evolution where vary condition. Because condition-dependent readily evolves for underlying conflict, show intense populations are Such intensified reduces mean fitness thus generate negative association between size. The impact demography especially likely to be detrimental genetic basis coevolves with conflict. This occurs because selection favors alleles (the so-called good genes effect), producing feedback drives harm. Our results indicate presence harm, effect fact easily becomes populations.
