Evidence has accumulated in recent decades on the drastic impact of climate change biodiversity. Warming temperatures have induced changes species physiology, phenology, and decreased body size. Such modifications can population dynamics could lead to life cycle demography. More specifically, conceptual frameworks predict that global warming will severely threaten tropical ectotherms while temperate should resist or even benefit from higher temperatures. However, experimental studies...
Comparative studies of mortality in the wild are necessary to understand evolution aging; yet, ectothermic tetrapods underrepresented this comparative landscape, despite their suitability for testing evolutionary hypotheses. We present a study aging rates and longevity across tetrapod ectotherms, using data from 107 populations (77 species) nonavian reptiles amphibians. test hypotheses how thermoregulatory mode, environmental temperature, protective phenotypes, pace life history contribute...
Secondary sexual characters may have evolved in part to signal resistance parasites. Avian song has been hypothesized be involved this process, but the role of parasites modulating acoustic communication systems birds remains largely unknown, owing lack experiments. We studied relationship between parasitism, testosterone, performance, and mating success male collared flycatchers (Ficedula albicollis) by experimentally challenging their immune system with a novel antigen. predicted that...
Genes of the major histocompatibility complex (MHC) are most polymorphic loci known in vertebrates. Two main hypotheses have been put forward to explain maintenance MHC diversity: pathogen-mediated selection and MHC-based mate choice. Host-parasite interactions can maintain diversity via frequency-dependent selection, heterozygote advantage, diversifying (spatially and/or temporally heterogeneous selection). In this study, we wished investigate nature acting on class I across spatially...
Aging is the price to pay for acquiring and processing energy through cellular activity life history productivity. Climate warming can exacerbate inherent pace of aging, as illustrated by a faster erosion protective telomere DNA sequences. This biomarker integrates individual parental effects germline, but whether intra- intergenerational dynamics underlies population trends remains an open question. Here, we investigated covariation between history, length (TL), extinction risk among three...
ABSTRACT Nocturnal temperatures are increasing at a pace exceeding diurnal in most parts of the world. The role warmer nocturnal animal ecology has received scant attention and studies focus on or daily descriptors thermal environments' temporal trends. Yet, available evidence from plant insect suggests that organisms can exhibit contrasting physiological responses to warming. Limiting trends thus result incomplete misleading interpretations ability species cope with global Although they...
While males gain obvious direct advantages from multiple mating, the reproductive capacity of females is more constrained. The reason why polyandry evolved in therefore open to many conjectures. One hypothesis postulates that indirect benefits by increasing probability siring young high quality males. To explore this hypothesis, we used natural variation value and undergo through age. age-related phenotypic performance might then induce variations mating strategies females. Using common...
Sexually transmitted diseases have often been suggested as a potential cost of multiple mating and playing major role in the evolution systems. Yet there is little empirical data relating strategies to sexually microorganisms wild populations. We investigated whether behaviour influences diversity composition cloacal assemblages by comparing bacterial communities cloaca monandrous polyandrous female common lizards Zootoca vivipara sampled after period. found that females harboured more...
Substantial plastic variation in phenology response to environmental heterogeneity through time the same population has been uncovered many species. However, our understanding of differences reaction norms among populations from a given species remains limited. As plasticity phenological traits is often influenced by local thermal conditions, we expect temperature generate between populations. Here, explored temporal parturition date across 11 common lizard (Zootoca vivipara) four mountain...
Abstract Reproduction involves considerable reorganization in an organism's physiology that incurs potential toxicity for cells (e.g., oxidative stress) and decrease fitness. This framework has been the cornerstone of so‐called ‘oxidative cost reproduction’, a theory remains controversial relatively overlooked non‐model ectotherms. Here, we used two complementary approaches natural controlled conditions to test whether altered access climate (water temperature resources) alters status...
Understanding the relationships between biodiversity and ecosystem functioning stands as a cornerstone in ecological research. Extensive evidence now underscores profound impact of species loss on stability dynamics functions. However, it remains unclear whether genetic diversity within key yield similar consequences. Here, we delve into intricate relationship diversity, functions across three trophic levels —primary producers, primary consumers, secondary consumers— natural aquatic...

Recent studies have shown UV vision and markings to be important in vertebrates, particularly birds, where behavioral experiments demonstrated its potential importance sexual selection. However, there has been no genetic evidence that determine patterns of evolution among natural populations. Here we report molecular are associated with the pattern gene flow Tenerife lizard ( Gallotia galloti ). This species vicariance-induced, approximate east–west lineages closely congruent primary...
Abstract The common lizard ( Lacerta vivipara ) is a small live‐bearing lacertid that reproduces once year. In order to document the poorly known mating system of this species, we present here an assessment multiple paternity using microsatellite markers. Paternities were established within 122 clutches belonging two wild populations from contrasted areas and four seminatural enclosed populations. proportion multiply sired was found be very high (between 50.0% 68.2%) similar among...
Sex allocation theory proposes that parents should bias the sex ratio of their offspring if reproductive value one is greater than other. In monogamous blue tit (Parus caeruleus), males have a variance in success females, and high-quality higher females due to extrapair paternity. Consequently, mating with attractive are expected produce broods biased toward sons, as sons benefit more daughters from inheriting father's characteristics. Song plumage color birds secondary sexual characters...
Abstract This article documents the addition of 238 microsatellite marker loci to Molecular Ecology Resources Database. Loci were developed for following species: Alytes dickhilleni , Arapaima gigas Austropotamobius italicus Blumeria graminis f. sp. tritici Cobitis lutheri Dendroctonus ponderosae Glossina morsitans Haplophilus subterraneus Kirengeshoma palmata Lysimachia japonica Macrolophus pygmaeus Microtus cabrerae Mytilus galloprovinciali s, Pallisentis ( Neosentis ) celatus Pulmonaria...
Mate choice is known as an important behavior allowing females to choose the best mate increase their reproductive success. To estimate male quality, can use multiple traits. Among those, recent studies have shown that personality traits could play role in they are often linked major life-history and be heritable. However, because relationships between context dependent, expected types according mating context. In this study on common lizards (Zootoca vivipara), we examined of female after...
Loss in intraspecific diversity can alter ecosystem functions, but the underlying mechanisms are still elusive, and biodiversity–ecosystem function (iBEF) relationships have been restrained to primary producers. Here, we manipulated genetic functional richness of a fish consumer ( Phoxinus phoxinus ) test whether iBEF exist species they more likely sustained by or richness. We found that both genotypic affected functioning, either independently interactively. reduced benthic invertebrate...
Abstract Avian brood parasites reduce the reproductive output of their hosts and thereby select for defence mechanisms such as ejection parasitic eggs. Such simultaneously counter-defences in parasites, causing a coevolutionary arms race. Although models assume that defences are genetically influenced, this has never been demonstrated parasites. Here, we give strong evidence genetic differences between ejector nonejectors, which could allow study host at level, well studies maintenance...
Immune defenses are of great benefit to hosts, but reducing the impact infection by mounting an immune response also entails costs. However, physiological mechanisms that generate costs remain poorly understood. Moreover, majority studies investigating consequences challenge in vertebrates have been conducted on mammals and birds. The aim this study is investigate during gestation ectothermic species. Indeed, because species unable internally regulate their body temperature, apportionment...
