Data from: Cold adaptation in the Asian tiger mosquito’s native range precedes its invasion success in temperate regionsStéphanie Sherpa, Michael G. B. Blum & Laurence Després
Adaptation to environmental conditions within the native range of exotic species can condition the invasion success of these species outside their range. The striking success of the Asian tiger mosquito, Aedes albopictus, to invade temperate regions has been attributed to the winter survival of diapause eggs in cold environments. In this study, we evaluate genetic polymorphisms (SNPs) and wing morphometric variation among three biogeographical regions of the native range of A. albopictus. Reconstructed demographic histories...
Data from: Speciation with gene flow: evidence from a complex of alpine butterflies (Coenonympha, Satyridae)Thibaut Capblancq, Jesús Mavárez, Delphine Rioux & Laurence Després
Until complete reproductive isolation is achieved, the extent of differentiation between two diverging lineages is the result of a dynamic equilibrium between genetic isolation and mixing. This is especially true for hybrid taxa, for which the degree of isolation in regard to their parental species is decisive in their capacity to rise as a new and stable entity. In this work, we explored the past and current patterns of hybridization and divergence within a complex...
Using proxies of microbial community‐weighted means traits to explain the cascading effect of management intensity, soil and plant traits on ecosystem resilience in mountain grasslandsGabin Piton, Nicolas Legay, Cindy Arnoldi, Sandra Lavorel, Jean-Christophe Clément, Arnaud Foulquier & Jean Christophe Clément
1. Trait-based approaches provide a framework to understand the role of functional biodiversity on ecosystem functioning under global change. While plant traits have been reported as potential drivers of soil microbial community composition and resilience, studies directly assessing microbial traits are scarce, limiting our mechanistic understanding of ecosystem functioning. 2. We used microbial biomass and enzyme stoichiometry, and mass-specific enzymes activity as proxies of microbial community-weighted mean (CWM) traits, to infer trade-offs in microbial strategies...
Plants adapted to extreme conditions can be at high risk from climate change; arctic-alpine plants, in particular, could “run out of space” as they are out-competed by expansion of woody vegetation. Mountain regions could potentially provide safe sites for arctic-alpine plants in a warmer climate, but empirical evidence is fragmentary. Here we present a 24,000-year record of species persistence based on sedimentary ancient DNA (sedaDNA) from Lake Bolshoye Shchuchye (Polar Urals). We provide robust evidence...
Environmental and biotic drivers of soil microbial β‐diversity across spatial and phylogenetic scalesLoïc Chalmandrier, Johan Pansu, Lucie Zinger, Frederic Boyer, Eric Coissac, Alexandre Génin, Ludovic Gielly, Sébastien Lavergne, Nicolas Legay, Vincent Schilling, Pierre Taberlet, Tamara Münkemüller & Wilfried Thuiller
Soil microbial communities play a key role in ecosystem functioning but still little is known about the processes that determine their turnover (β-diversity) along ecological gradients. Here, we characterize soil microbial β-diversity at two spatial scales and at multiple phylogenetic grains to ask how archaeal, bacterial and fungal communities are shaped by abiotic processes and biotic interactions with plants. We characterized microbial and plant communities using DNA metabarcoding of soil samples distributed across and within...
Data from: Unveiling the food webs of tetrapods across Europe through the prism of the Eltonian nicheLouise O'Connor, Laura J. Pollock, João Braga, Gentile Francesco Ficetola, Alessandro Montemaggiori, Luigi Maiorano, Wilfried Thuiller, Marc Ohlmann & Camille Martinez-Almoyna
Aim Despite the recent calls on integrating the interaction networks into the study of large‐scale biodiversity patterns, we still lack a basic understanding of the functional characteristics of large interaction networks and how they are structured across environments. Here, building on recent advances in network science around the Eltonian niche concept, we aim to characterize the trophic groups in a large food web, and understand how these trophic groups vary across space. Location Europe and...
Through the taste buds of a large herbivore: foodscape modeling contributes to an understanding of forage selection processesAntoine Duparc, Mathieu Garel, Pascal Marchand, Dominique Dubray, Daniel Maillard & Anne Loison
How large herbivores track resource quantity and quality through time has formed the core of an abundance of literature on migratory populations in recent decades. Yet, relating foraging processes and habitat selection patterns in resident populations, where spatial heterogeneity of food resources is fine‐grained and/or where the portion of edible plants (i.e. the foodscape) is low, is challenging. We addressed this issue in a mountain population of chamois Rupicapra rupicapra, an intermediate feeder, whose individuals...
