Article
Accurate heritability estimates for fitness‐related traits are required to predict an organism’s ability to respond to global change. Heritability estimates are theoretically expected to be inflated if, due to limited dispersal, individuals that share genes are also likely to share similar environments. However, if relatives occupy similar environm...

Changes in environmental conditions alter host–parasite interactions, raising the need for effective epidemiological surveillance. Developing operational, accurate, and cost‐effective methods to assess individual infection status and potential for pathogen spread is a prerequisite to anticipate future disease outbreaks in wild populations. For endo...
Article
Toll‐like Receptors (TLR) play a central role in recognition and host frontline defence against a wide range of pathogens. A number of recent studies have shown that TLR genes (Tlrs) often exhibit large polymorphism in natural populations. Yet, there is little knowledge on how this polymorphism is maintained and how it influences disease susceptibi...

Large carnivores play a pivotal regulating role in maintaining healthy and balanced ecosystems; however, most of them are rare and elusive, and knowledge about their resource consumption is scarce. Traditional methods based on morphological identification of undigested remains are labor intensive and often not sufficiently accurate, leading to erro...
Article
Full-text available
In vertebrates, offspring survival often decreases with increasing maternal age. While many studies have reported a decline in fitness‐related traits of offspring with increasing maternal age, the study of senescence in maternal effect through age‐specific changes in offspring physiological condition is still at its infancy. We assessed the influen...
Article
Full-text available
Many species are structured in social groups (SGs) where individuals exhibit complex mating strategies. Yet, most population genetic studies ignore SGs either treating them as small random-mating units or focusing on a higher hierarchical level (the population). Empirical studies acknowledging SGs have found an overall excess of heterozygotes withi...

Species that evolved in temperate regions during the Pleistocene experienced periods of extreme climatic transitions. Consequent population fragmentation and dynamics had the potential to generate small, isolated populations where the influence of genetic drift would be expected to be strong. We use comparative genomics to assess the evolutionary i...
Article
Full-text available
While it is now broadly accepted that inter-individual variation in the outcomes of host–pathogen interactions is at least partially genetically controlled, host immunogenetic characteristics are rarely investigated in wildlife epidemiological studies. Furthermore, most immunogenetic studies in the wild focused solely on the major histocompatibilit...
Article
Full-text available
Assessing the evolutionary potential of animal populations in the wild is crucial to understanding how they may respond to selection mediated by rapid environmental change (e.g. habitat loss and fragmentation). A growing number of studies have investigated the adaptive role of behaviour, but assessments of its genetic basis in a natural setting rem...

Epidemiological investigations implemented in wild and domestic ruminants evidenced a reservoir for Brucella in Capra ibex in the French Alps. Vaccination was considered as a possible way to control Brucella infection in this wildlife population. Twelve ibexes and twelve goats were allocated into four groups housed separately, each including six ma...
Article
Whether female mating tactics vary with age based on their preference for mates remains poorly documented. To fill this knowledge gap, we examined how maternal age is related to the age of their mates using detailed individual long‐term monitoring of a genotyped and pedigreed European roe deer (Capreolus capreolus, Linnaeus, 1758) population. We f...

Estimating the evolutionary potential of quantitative traits and reliably predicting responses to selection in wild populations are important challenges in evolutionary biology. The genomic revolution has opened up opportunities for measuring relatedness among individuals with precision, enabling pedigree‐free estimation of trait heritabilities in...

Background: Understanding the genetic and environmental mechanisms governing variation in morphology or phenology in wild populations is currently an important challenge. While there is a general consensus that selection is stronger under stressful conditions, it remains unclear whether the evolutionary potential of traits should increase or decrea...
Article
Pour comprendre les modalités d’infection d’une population naturelle par un agent pathogène et de transmission en son sein, il est nécessaire de connaître les caractéristiques génétiques et immunogénétiques de cette population. En effet, la diversité génétique est essentielle pour que les populations puissent s’adapter aux risques multi-parasitaire...

The relative effect of past climate fluctuations and anthropogenic activities on current biome distribution is subject to increasing attention, notably in biodiversity hotspots. In Madagascar, where humans arrived in the last ~4-5,000 years, the exact causes of the demise of large vertebrates that cohabited with humans is yet unresolved. The prevai...
Article
Dispersal is a key life-history trait governing the response of individuals, populations and species to changing environmental conditions. In the context of global change, it is therefore essential to better understand the respective role of condition-, phenotype-, and genetic-dependent drivers of dispersal behaviour. Although the importance of imm...

Aim Most animal species live in spatially and temporally heterogeneous landscapes where resources are unevenly distributed. Consequently, individuals must adapt their migratory behaviour to optimize feeding and breeding opportunities. Here, we assess the role of life-history (anadromy) and seascape (a derivation of the concept of landscape) heterog...
Article
Full-text available
Understanding how immune genetic variation is shaped by selective and neutral processes in wild populations is of prime importance in both evolutionary biology and epidemiology. The European roe deer (Capreolus capreolus) has considerably expanded its distribution range these last decades, notably by colonizing agricultural landscapes. This range s...

Although theoretical studies have predicted a link between individual multilocus heterozygosity and dispersal, few empirical studies have investigated the effect of individual heterozygosity on dispersal propensity or distance. We investigated this link using measures of heterozygosity at 12 putatively neutral microsatellite markers and natal dispe...

Rapid and accurate sex-identification of salmonids has remained an important challenge for aquaculture and wild population study and management. A molecular method looking for the presence of the male-specific sdY gene has recently been proposed. However, the size of the amplified fragment (~500pb) and the DNA revealing technique (agarose-gel elect...
