Introduction
I am interested in the evolutionary ecology of animal behaviour in wild birds. Most of my work focuses on the mechanisms that explain the variation of animal behaviour and their meaning within an evolutionary context. I use red grouse (Lagopus lagopus scoticus), common kestrels (Falco tinnunculus) and pied flycatchers (Ficedula hypoleuca) as model species which allow me to use a combination of experimental work integrating behavioural, physiological, molecular and quantitative genetic tools.

Article
Full-text available
Individuals can gain fitness benefits and costs through their mates. However, studies on sexual selection have tended to focus on genetic benefits. A potentially widespread cost of pairing with a parasitized mate is that doing so will increase an individual's parasite abundance. Such a cost has been overlooked in systems in which parasites are indi...
Article
Full-text available
Environmental conditions and individual strategies in early life may have a profound effect on fitness. A critical moment in the life of an organism occurs when an individual reaches independence and stops receiving benefits from its relatives. Understanding the consequences of individual strategies at the time of independence requires quantificati...
Article
Full-text available
Knowledge of the genetic basis of sexual ornaments is essential to understand their evolution through sexual selection. Although carotenoid-based ornaments have been instrumental in the study of sexual selection, given the inability of animals to synthesize carotenoids de novo, they are generally assumed to be influenced solely by environmental var...
Article
Full-text available
Flight initiation distance (FID), a measure of an animal’s tolerance to human disturbance and a descriptor of its fear of humans, is increasingly employed for conservation purposes and to predict the response of species to urbanization. However, most work devoted to understanding variability in FID has been conducted at the population level and lit...
Article
Full-text available
Understanding and forecasting the effects of environmental change on wild populations requires knowledge on a critical question: do populations have the ability to evolve in response to that change? However, our knowledge on how evolution works in wild conditions under different environmental circumstances is extremely limited. We investigated how...
Article
Full-text available
Oscine birds preferentially respond to certain sounds over others from an early age, which focuses subsequent learning onto sexually relevant songs. Songs vary both across species and, due to cultural evolution, among populations of the same species. As a result, early song responses are expected to be shaped by selection both to avoid the fitness...
Article
Identifying the environmental drivers of variation in fitness‐related traits is a central objective in ecology and evolutionary biology. Temporal fluctuations of these environmental drivers are often synchronized at large spatial scales. Yet, whether synchronous environmental conditions can generate spatial synchrony in fitness‐related trait values...
Article
Full-text available
Most studies of phenotypic selection in the wild have focused on morphological and life-history traits and looked at abiotic (climatic) variation as the main driver of selection. Consequently, our knowledge of the effects of biotic environmental variation on phenotypic selection on sexual traits is scarce. Population density can be considered a pro...
Article
Full-text available
Mating system theory predicts that social polygyny—when one male forms pair bonds with two females—may evolve by female choice in species with biparental care. Females will accept a polygynous male if the benefit of mating with a male providing high quality genes or rearing resources outweighs the cost of sharing mate assistance in parental care. B...

Full-text available
Telomere length and shortening rate are increasingly used as biomarkers for long-term costs in ecological and evolutionary studies because of their relationships with survival and fitness. Both early-life conditions and growth, and later-life stressors can create variation in telomere shortening rate. Studies on between-population telomere length a...

Resumen: El estudio de los factores ambientales que pueden explicar los niveles de estrés fisiológico en poblaciones naturales es de vital importancia para especies vulnerables, ya que puede influir en la mortalidad de los individuos y, por tanto, en la viabilidad poblacional. En este trabajo se exploran los condicionantes ambientales que pueden ex...
Article
Full-text available
The origin of natural selection is linked to environmental heterogeneity, which influences variation in relative fitness among phenotypes. However, individuals in wild populations are exposed to a plethora of biotic and abiotic environmental factors. Surprisingly, the relative influence of multiple environmental conditions on relative fitness of ph...
Article
Full-text available
Why females engage in social polygyny remains an unresolved question in species where the resources provided by males maximize female fitness. In these systems, the ability of males to access several females, as well as the willingness of females to mate with an already mated male, and the benefits of this choice, may be constrained by the socio-ec...

Telomere length and shortening rate are increasingly used as biomarkers for long-term costs in ecological and evolutionary studies because of their relationships with survival and fitness. Telomere length can be heritable, but both early-life conditions and later-life stressors can create variation in telomere shortening rate. Studies on between-po...

Full-text available
Pied Flycatchers Ficedula hypoleuca are known to be victims of nest killings in contexts of competition for nest boxes. However, there is only anecdotal information on their opposite role as perpetrators of nest takeovers and occasional killings of other songbirds. Over 31 years we examined whether competition with Great Tits Parus major over nest...

The role of glacial refugia in shaping contemporary species distribution is a long‐standing question in phylogeography and evolutionary ecology. Recent studies are questioning previous paradigms on glacial refugia and postglacial recolonization pathways in Europe, and more flexible phylogeographic scenarios have been proposed. We used the widesprea...
Presentation
Full-text available
One of the major goals in evolutionary biology is to understand how the interplay between natural selection and genetic variation results in microevolution and local adaptation. However, microevolutionary responses to selection for advanced laying date are lacking despite a consistent directional selection on early laying date. Nevertheless, mechan...
Article
Full-text available
Dispersers are not a random subset of the source population and there is considerable evidence that they differ from non-dispersers in a number of phenotypic traits. However, it is not clear whether the magnitude and direction of these differences vary over time. Between 1988 and 2016, we investigated patterns of phenotype-dependent dispersal of pi...

Full-text available
Large carnivores are recolonizing parts of their historical range in Europe, a heavily modified human landscape. This calls for an improvement of our knowledge on how large carnivores manage to coexist with humans, and on the effects that human activity has on large carnivore behaviour, especially in areas where carnivore populations are still enda...
Article
The rate of occupation of territories or nest locations has been proposed as a suitable surrogate of breeding territory/habitat quality when more precise, but costly, measures are not available. However, whether the frequency of breeding territory occupancy actually reflects its quality regardless of the habitat type is unclear. We address this iss...

Conference Paper
Full-text available
Selection, understood as a non-random reproduction or survival of individuals differing in their phenotype, is a striking precursor of evolutionary change. There is a plethora of studies showing how the differential expression of certain traits is selected by natural or sexual selection, as they confer survival or reproductive advantages to the ind...
Article
Full-text available
The cost of reproduction is a key concept in life-history trade-offs. However, our understanding of the reproductive costs is biased towards measures of reproductive effort obtained before offspring independence. During the post-fledging dependence period (PFDP), it is well known that parents feed and protect their offspring. However, the effort de...

Identifying environmental factors that drive selection in natural populations will help to unravel and anticipate evolutionary changes in wild animal populations facing global change. The timing of reproduction (laying date) in birds is widely used to compare evolutionary responses to environmental change. We explored the relative influence of 16...

Animal personality is defined as the inter-individual differences in behaviour consistent across time and contexts. The most common way to study individual differences in behaviour is the shy-bold axis, in which bold individuals are characterized to be more aggressive and prone to risk than shy individuals. Variation in personality has been associa...
Article
Full-text available
Order of birth has profound consequences on offspring across taxa during development and can have effects on individuals later in life. In birds, differential maternal allocation and investment in their progeny lead to variance in the environmental conditions that offspring experience during growth within the brood. In particular, laying and hatchi...
Article
Full-text available
The expression of elaborate sexual displays is associated with individual quality ensuring reliable information about the bearers. However, the associated cost of expressing enhanced sexual traits is expected to change according to environmental circumstances. Specifically, the cost of maintaining or producing a signal is predicted to increase when...

Background: Vole outbreaks have been extensively described along with their impacts on humans, particularly in agricultural areas. The use of rodenticides is a common legal practice to minimise crop damage induced by high vole density for biocidal use. However, rodenticides can have negative direct and indirect impacts on non-target species that f...
Conference Paper
Full-text available
The duration of the post-fledgling dependence period (PFDP) is expected to be ruled by the parent-offspring conflict. Accordingly, while offspring will try to prolong their dependence, an increased PFDP imposed a cost to the parents. However, the potential fitness benefits and cost for offspring and parents respectively remain scarcely explored. He...
Article
Full-text available
Intrasexual competition in female birds is a widespread phenomenon but remains scarcely explored. Females compete for limited resources and the expression of signals that indicate their social status will be favoured by natural selection, generating a dominance hierarchy among individuals. However, which signals might be involved in femaleefemale c...

Stress is ubiquitous in the life of animals and a key determinant of their well-being and fitness. By quantifying levels of feather corticosterone in growing feathers (CORTf), we measured integrated stress responses in a monogamous game bird, the red grouse Lagopus lagopus scoticus. We investigated the effects of parasites and social mate choice on...

The carotenoid-based ornaments displayed by many birds often play key roles in social and sexual signalling, revealing information about individual quality. However, the proximate regulation of the honesty of sexual traits remains controversial. Understanding the mechanisms of coloured trait production and maintenance requires an accurate descripti...
Article
Full-text available
Secondary sexual traits displayed by males and females may have evolved as a signal of individual quality. However, both individual quality and investment on producing or maintaining enhanced sexual traits change as individuals age. At the same time, the costs associated to produce sexual traits might be attenuated or increased if environmental con...

Sexual dimorphism (SD) has evolved in response to selection pressures that differ between sexes. Since such pressures change across an individual's life, SD may vary within age classes. Yet, little is known about how selection on early phenotypes may drive the final SD observed in adults. In many dimorphic species, juveniles resemble adult females...
