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).

Selection on phenotypic plasticity favors thermal canalization

Proceedings of the National Academy of Sciences, Journal Year: 2020, Volume and Issue: 117(47), P. 29767 - 29774

Published: Nov. 9, 2020

Significance Organisms are increasingly challenged by increasing temperatures due to climate change. In insects, body strongly affected ambient temperatures, and insects therefore expected suffer from heat stress, potentially reducing survival reproductive success leading elevated extinction risks. We investigated how temperature fitness in two insect species the temperate zone. Male female survivorship benefitted more low than did success, which increased with higher revealing a thermal conflict between components. plasticity reduced survival, natural sexual selection operated on such plasticity. Our results reveal negative consequences of show that these have limited ability buffer stress.

Concerted evolution of metabolic rate, economics of mating, ecology, and pace of life across seed beetles

Proceedings of the National Academy of Sciences, Journal Year: 2022, Volume and Issue: 119(33)

Male–female coevolution has taken different paths among closely related species, but our understanding of the factors that govern its direction is limited. While it clear ecological factors, life history, and economics reproduction are connected, divergent links often obscure. We propose a complete requires conceptual integration metabolic phenotypes. Metabolic rate, nexus history evolution, constrained by may exert important direct indirect effects on evolution sexual dimorphism. performed standardized experiments in 12 seed beetle species to gain rich set sex-specific measures phenotypes, traits, mating analyzed multivariate data using phylogenetic comparative methods.

The ecology of sexual conflict: Temperature variation in the social environment can drastically modulate male harm to females

Functional Ecology, Journal Year: 2019, Volume and Issue: 33(4), P. 681 - 692

Published: Jan. 4, 2019

Abstract Sexual conflict is a fundamental driver of male/female adaptations, an engine biodiversity and crucial determinant population viability. frequently leads to behavioural adaptations that allow males displace their rivals, but in doing so harm those same females they are competing access, which can decrease viability facilitate extinction. We far from understanding what factors modulate the intensity sexual particularly role ecology mediating underlying adaptations. In this study, we show that, Drosophila melanogaster , variations environmental temperature ±4°C male impact on female fitness by between 45% 73%. Rate‐sensitive estimates indicate such modulation results average rescue productivity 7% at colder temperatures 23% hotter temperatures. Our results: (a) thermal social interactions drastically via plasticity, (b) identify potentially ecological factor understand how operates nature (c), along with recent studies, suggest behaviourally plastic responses lessen negative effect face rapid changes.

Temperature drives pre‐reproductive selection and shapes the biogeography of a female polymorphism

Ecology Letters, Journal Year: 2019, Volume and Issue: 23(1), P. 149 - 159

Published: Nov. 6, 2019

Conflicts of interests between males and females over reproduction is a universal feature sexually reproducing organisms has driven the evolution intersexual mimicry, mating behaviours reproductive polymorphisms. Here, we show how temperature drives pre-reproductive selection in female colour polymorphic insect that subject to strong sexual conflict. These species have three morphs, one which male mimic. This polymorphism maintained by frequency-dependent conflict caused harassment. The frequency morphs varies geographically, with higher mimic at latitudes. We differential sensitivity faster maturation increases this morph north. results suggest during adult stage shaped abiotic factors frequency-independent operate earlier ontogeny these morphs.

Male harm suppresses female fitness, affecting the dynamics of adaptation and evolutionary rescue

Evolution Letters, Journal Year: 2023, Volume and Issue: 8(1), P. 149 - 160

One of the most pressing questions we face as biologists is to understand how climate change will affect evolutionary dynamics natural populations and these in turn population recovery. Increasing evidence shows that sexual selection favors viability local adaptation. However, can also foster conflict drive evolution male harm females. Male extraordinarily widespread has potential suppress female fitness compromise growth, yet currently ignore its net effects across taxa or influence on adaptation rescue. We conducted a comparative meta-analysis quantify impact found an overall negative effect fitness. Negative seem depend proxies selection, increasing inversely relative size species with strong sperm competition. then developed theoretical models explore affects show that, when depends adaptation, decline reduced, but at cost slowing down genetic This trade-off suggests eco-evolutionary feedback act like double-edged sword, reducing extinction risk by buffering demographic costs change, delaying variation mating system type mitigate this trade-off. Our work productivity, identifies mechanistic factors underlying variability such taxa, underscores acknowledging condition-dependence may be important processes adapt environmental change.

On the resolution of sexual conflict over shared traits

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2024, Volume and Issue: 291(2027)

Published: July 31, 2024

Anisogamy, different-sized male and female gametes, sits at the heart of sexual selection conflict between sexes. Sperm producers (males) egg (females) same species generally share most, if not all, genome, but frequently favours different trait values in each sex for traits common to both. The extent which this might be resolved, potential mechanisms by can occur, have been widely debated. Here, we summarize recent findings emphasize that once sexes evolve, is ongoing, therefore new always possible. In addition, largely a multivariate problem, involving combinations underpinned networks interconnected genes. Although these complexities hinder resolution, they also provide multiple possible routes decouple phenotypes permit sex-specific evolution. Finally, highlight difficulty study over shared promising directions future research.

The mating system affects the temperature sensitivity of male and female fertility

Functional Ecology, Journal Year: 2021, Volume and Issue: 36(1), P. 92 - 106

Published: Oct. 20, 2021

Abstract To mitigate the effects of climate change, it is important to understand species' responses increasing temperatures. This has often been done by studying survival or activity at temperature extremes. Before such extremes are reached, however, on fertility may already be apparent. Sex differences in thermal sensitivity (TSF) could impact species persistence under warming because female typically more limiting population growth than male fertility. However, little known about sex TSF. Here we first demonstrate that mating system can strongly influence TSF using seed beetle Callosobruchus maculatus . We exposed populations carrying artificially induced mutations two generations short‐term experimental evolution alternative systems, manipulating opportunity for natural and sexual selection mutations. then measured males females subjected juvenile adult heat stress. Populations kept had higher fitness, but similar TSF, compared control relaxed selection. males, strikingly, this difference increased over only evolving hypothesized an increase male‐induced harm during played a central role driving evolved difference, indeed, remating conditions harassment reduced both Moreover, show manipulation parameters C. generates intraspecific variation equal found among diverse set studies insects.
