Data from: The global geography of fish diadromy modesAnaïs Chalant, Céline Jézequel, Philippe Keith & Bernard Hugueny
Aim: Geographical gradients in resource production are likely to translate into macro-ecological patterns in the biodiversity of migratory organisms but few studies have addressed this question at a global scale. Here we tested a hypothesis based on uncoupled latitudinal gradients in marine and freshwater primary productivities aimed at explaining where (e. g. at which latitude) and at which stage of the life cycle (larvae: amphidromy, juvenile: catadromy, adult: anadromy) migration from ocean to freshwater occurs...
Data from: RAD‐sequencing for estimating genomic relatedness matrix‐based heritability in the wild: a case study in roe deerLaura Gervais, Charles Perrier, Maria Bernard, Joël Merlet, Josephine M. Pemberton, Benoit Pujol & Erwan Quemere
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 wild populations. However, until now, most quantitative genetic studies based on a genomic relatedness matrix (GRM) have focused on long-term monitored populations for which traditional pedigrees were also available, and have often...
Data from: Biotic and abiotic drivers of species loss rate in isolated lakesCéline Bellard, Göran Englund & Bernard Hugueny
1. Today, anthropogenic impacts are causing a serious crisis for global biodiversity, with rates of extinction increasing at an unprecedented rate. Extinctions typically occur after a certain delay and understanding the mechanisms causing delays is a key challenge for both fundamental and applied perspectives. 2. Here, we make use of natural experiments, the isolation of lakes by land up-lift in Northern Scandinavia, to examine how yearly extinction rates are affected by time since isolation and...
Genomic footprints of a biological invasion: introduction from Asia and dispersal in Europe of the topmouth gudgeon (Pseudorasbora parva)Miguel Baltazar-Soares, Simon Blanchet, Julien Cote, Ali Serkhan Tarkan, Eva Záhorská, Rodolphe Gozlan & Christophe Eizaguirre
Facilitated by the intensification of global trading, the introduction and dispersal of species to areas in which they are historically non-native is nowadays common. From an evolutionary standpoint, invasions are paradoxical: not only non-native environments could be different from native ones for which introduced individuals would be ill-adapted, but also small founding population size should be associated with reduced adaptive potential. As such, biological invasions are considered valuable real-time evolutionary experiments. Here, we investigated the...
