Abstract The recent availability of next‐generation sequencing (NGS) has made possible the use dense genetic markers to identify regions genome that may be under influence selection. Several statistical methods have been developed recently for this purpose. Here, we present results an individual‐based simulation study investigating power and error rate popular or scan methods: linear regression, Bayescan, BayEnv LFMM. Contrary previous studies, focus on complex, hierarchical population...
The evolutionary basis of domestication has been a longstanding question and its genetic architecture is becoming more tractable as domestic species become genome-enabled. Before established worldwide, sheep goats were domesticated in the fertile crescent 10,500 years before present (YBP) where their wild relatives remain. Here we sequence genomes Asiatic mouflon Bezoar ibex goat center compare with that domestics from local, traditional, improved breeds. Among genomic regions carrying...
Summary Estimating heritability of traits in wild populations is a major prerequisite to understand their evolution. Until recently, most estimates had been obtained using parent‐offspring regressions. However, the popularity animal models, that is, (generalized) linear mixed models assessing genetic variance component based on population pedigree information, has markedly increased past few years. Animal are claimed perform better than parent–offspring regressions mainly because they use...
Abstract Methods for inference and interpretation of evolutionary quantitative genetic parameters, prediction the response to selection, are best developed traits with normal distributions. Many interest, including many life history behavioral traits, have inherently nonnormal The generalized linear mixed model (GLMM) framework has become a widely used tool estimating parameters traits. However, whereas GLMMs provide on statistically convenient latent scale, it is often desirable express...
Summary Genome‐scan methods are used for screening genomewide patterns of DNA polymorphism to detect signatures positive selection. There two main types methods: (i) ‘outlier’ detection based on that loci with high differentiation compared the rest genome and (ii) environmental association test between allele frequencies variables. We present a new ‐based genome‐scan method, BayeScEnv, which incorporates information in form ‘environmental differentiation’. It is F model, but, as opposed...
The rate of adaptive evolution, the contribution selection to genetic changes that increase mean fitness, is determined by additive variance in individual relative fitness. To date, there are few robust estimates this parameter for natural populations, and it therefore unclear whether evolution can play a meaningful role short-term population dynamics. We developed applied quantitative methods long-term datasets from 19 wild bird mammal populations found that, while vary between fitness...
Significance Many ecological and evolutionary processes strongly depend on the way natural selection varies over time. However, a gap remains when trying to connect theoretical predictions empirical work this question: Most theory assumes that adaptation involves tracking moving optimum phenotype through time, but is seldom estimated empirically. Here, we have assembled large database of wild bird mammal populations, estimate patterns fluctuations in breeding date its influence variability...
Abstract Linear mixed‐effects models are frequently used for estimating quantitative genetic parameters, including the heritability, as well repeatability, of traits. Heritability acts a filter that determines how efficiently phenotypic selection translates into evolutionary change, whereas repeatability informs us about individual consistency As quantities biological interest, it is important denominator, variance in both cases, reflects amount relevant ecological setting. The current...
Abstract Local adaptation and phenotypic plasticity are two important characteristics of alpine plants to overcome the threats caused by global changes. Among species, Arabis alpina is characterised an unusually wide altitudinal amplitude, ranging from 800 3,100 m elevation in French Alps. Two non‐exclusive hypotheses can explain presence A. across this broad ecological gradient: adaptive or local adaptation, making species especially useful better understand these phenomena plant species....
Abstract Background Uncertainty in comparative analyses can come from at least two sources: a) phylogenetic uncertainty the tree topology or branch lengths, and b) due to intraspecific variation trait values, either measurement error natural individual variation. Most methods do not account for such uncertainties. Not accounting these sources of leads false perceptions precision (confidence intervals will be too narrow) inflated significance hypothesis testing (e.g. p-values small). Although...
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...
For small and isolated populations, the increased chance of mating between related individuals can result in a substantial reduction individual population fitness. Despite increasing availability genomic data to measure inbreeding accurately across genome, depression studies for threatened species are still scarce due difficulty measuring fitness wild. Here, we investigate extensively monitored Tiritiri Mātangi island Aotearoa New Zealand passerine, hihi (Notiomystis cincta). First, using...
Phylogenetic comparative methods (PCMs), especially ones based on linear models, have played a central role in understanding species' trait evolution. These methods, however, usually assume that phylogenetic trees are known without error or uncertainty, but this assumption is most likely incorrect. So far, Markov chain Monte Carlo (MCMC)-based Bayesian mainly been deployed to account for such "phylogenetic uncertainty" PCMs. Herein, we propose an approach with which uncertainty incorporated...
To predict if a threatened species can adapt to changing selective pressures, it is crucial understand the genetic basis of adaptive traits, especially in historically affected by severe bottlenecks. We estimated heritability three hihi ( Notiomystis cincta ) morphological traits known be under selection (nestling tarsus length, body mass and head–bill length) using 523 individuals 39 699 single nucleotide polymorphisms (SNPs) from 50 K Affymetrix SNP chip. then examined architecture via...
Species occupy diverse, heterogeneous environments, which expose populations to spatially varied selective pressures. Populations in different environments can diverge due local adaptation. However, neutral evolution also drive population divergence. Thus, testing for adaptation requires a baseline differentiation. The classical QST-FST comparison was developed this purpose. Yet, frequently fails account the complexities of structure because theory underlying assumes that all subpopulations...
Abstract Faced with climate warming, ectothermic species shift their breeding phenology, which is in part attributed to an acceleration of gestation or incubation warmer environments. Thermal may have important fitness implications for females and offspring by impacting maternal homeostasis, embryonic development hatching date, but these benefits costs been poorly documented. In addition, while change characterised a stronger trend night‐time than daytime warming concurrent alterations food...
Abstract Urbanization is occurring globally at an unprecedented rate and, despite the eco-evolutionary importance of individual variation, we still have limited insight on how phenotypic variation modified by anthropogenic environmental change. can increase differences in some contexts, but whether this generalizable to behavioral traits, which directly affect organisms interact with, and respond to, not well known. Here examined across three traits linked stress reactivity, anti-predator...
