Data from: From gestation to weaning: combining robust design and multi-event models unveils cost of lactation in a large herbivoreQuentin Richard, Carole Toïgo, Joël Appolinaire, Anne Loison & Mathieu Garel
1. The cost of current reproduction on survival or future reproduction is one of the most studied trade-offs governing resource distribution between fitness components. Results have often been clouded, however, by the existence of individual heterogeneity, with high-quality individuals able to allocate energy to several functions simultaneously, at no apparent cost. 2. Surprisingly, it has also rarely been assessed within a breeding season by breaking down the various reproductive efforts of females from gestation to...
Data from: Admixture between released and wild game birds: a changing genetic landscape in European mallards (Anas platyrhynchos)Pär Söderquist, Johan Elmberg, Gunnar Gunnarsson, Carl-Gustaf Thulin, Jocelyn Champagnon, Matthieu Guillemain, Jakub Kreisinger, Herbert H. T. Prins, Richard P. M. A. Crooijmans & Robert H. S. Kraus
Disruption of naturally evolved spatial patterns of genetic variation and local adaptations is a growing concern in wildlife management and conservation. During the last decade, releases of native taxa with potentially non-native genotypes have received increased attention. This has mostly concerned conservation programs, but releases are also widely carried out to boost harvest opportunities. The mallard, Anas platyrhynchos, is one of few terrestrial migratory vertebrates subjected to large-scale releases for hunting purposes. It is the...
Data from: The cost of growing large: sex-specific costs of post-weaning growth on body mass senescence in a wild mammalFrédéric Douhard, Jean-Michel Gaillard, Maryline Pellerin, Laurent Jacob & Jean-François Lemaître
Individual body mass often positively correlates with survival and reproductive success, whereas fitness costs of growing large are rarely detected in vertebrates in the wild. Evidence that adult body mass progressively declines with increasing age is accumulating across mammalian populations. Growing fast to a large body can increase the cellular damage accumulated throughout life, leading body growth in early life to be negatively associated with the rate of body mass senescence. Moreover, the onset of...
Data from: Mapping and explaining wolf recolonization in France using dynamic occupancy models and opportunistic dataJulie Louvrier, Christophe Duchamp, Valentin Lauret, Eric Marboutin, Sarah Cubaynes, Rémi Choquet, Christian Miquel & Olivier Gimenez
While large carnivores are recovering in Europe, assessing their distributions can help to predict and mitigate conflicts with human activities. Because they are highly mobile, elusive and live at very low density, modeling their distributions presents several challenges due to i) their imperfect detectability, ii) their dynamic ranges over time and iii) their monitoring at large scales consisting mainly of opportunistic data without a formal measure of the sampling effort. Here, we focused on wolves...
Data from: Landscape genetic analyses reveal fine-scale effects of forest fragmentation in an insular tropical birdAurélie Khimoun, William Peterman, Cyril Eraud, Bruno Faivre, Nicolas Navarro & Stéphane Garnier
Within the framework of landscape genetics, resistance surface modelling is particularly relevant to explicitly test competing hypotheses about landscape effects on gene flow. To investigate how fragmentation of tropical forest affects population connectivity in a forest specialist bird species, we optimized resistance surfaces without a priori specification, using least-cost (LCP) or resistance (IBR) distances. We implemented a two-step procedure in order (i) to objectively define the landscape thematic resolution (level of detail in classification scheme...
Data from: Introduction history overrides social factors in explaining genetic structure of females in Mediterranean mouflonElodie Portanier, Mathieu Garel, Sebastien Devillard, Pascal Marchand, Julie Andru, Daniel Maillard & Gilles Bourgoin
Fine-scale spatial genetic structure of populations results from social and spatial behaviors of individuals such as sex-biased dispersal and philopatry. However, the demographic history of a given population can override such socio-spatial factors in shaping genetic variability when bottlenecks or founder events occurred in the population. Here, we investigated whether socio-spatial organization determines the fine-scale genetic structure for both sexes in a Mediterranean mouflon (Ovis gmelini musimon×Ovis sp.) population in southern France 60 years after...
Data from: A single multiplex of twelve microsatellite markers for the simultaneous study of the brown hare (Lepus europaeus) and the mountain hare (Lepus timidus)Marie-Pauline Beugin, Jérôme Letty, Cécile Kaerle, Jean-Sébastien Guitton, Lina Muselet, Guillaume Queney & Dominique Pontier
The management of hunted species is challenging, as it must conciliate the conservation of species and their sustainable exploitation. Non-genetic tools are widely used in this context but they may present limitations notably when species can hybridize or when large-scale spatial monitoring is required to establish optimal management actions. This is why genetic tools have been more and more integrated in wildlife management practices. However, the markers proposed are often amplified in small multiplexes when...
The transport phase of the animal-mediated plant dispersal process is critical to dispersal effectiveness as it determines the spatial distribution of the diaspores released and their chance for further recruitment. Assessing this specific phase of the dispersal process generally requires combining diaspore retention times with the associated distances covered. Here, we specifically tested the effect of grooming behavior, interindividual contacts and ungulate fur on diaspore retention times and associated dispersal distances for the hooked diaspores...
