Despite no obvious barriers to gene flow in the marine realm, environmental variation and ecological specializations can lead to genetic differentiation in highly mobile predators. Here, we investigated the genetic structure of the harbor porpoise over the entire species distribution range in western Palearctic waters. Combined analyses of ten microsatellite loci and a 5,085 bases-pairs portion of the mitochondrial genome revealed the existence of three ecotypes, equally divergent at the mitochondrial genome, distributed in the...

Although the phylogeography of European mammals has been extensively investigated since the 1990s, many studies were limited in terms of sampling distribution, the number of molecular markers used and the analytical techniques employed, frequently leading to incomplete postglacial recolonisation scenarios. The broad-scale genetic structure of the European badger (Meles meles) is of interest as it may result from historic restriction to glacial refugia and/or recent anthropogenic impact. However, previous studies were based mostly on samples...
The roles of history, chance and selection have long been debated in evolutionary biology. Though uniform selection is expected to lead to convergent evolution between populations, contrasting histories and chance events might prevent them from attaining the same adaptive state, rendering evolution somewhat unpredictable. The predictability of evolution has been supported by several studies documenting repeatable adaptive radiations and convergence in both nature and laboratory. However, other studies suggest divergence among populations adapting to the...
Data from: Local and regional founder effects in lake zooplankton persist after thousands of years despite high dispersal potentialMarc Ventura, Adam Petrusek, Alexandre Miró, Eva Hamrová, Danilo Buñay, Luc De Meester & Joachim Mergeay
We reconstructed the genetic structure of a planktonic crustacean Daphnia longispina living in high mountain lakes and ponds in the Pyrenees to investigate whether it was shaped by persistent founder effects originating shortly after the last glacial maximum or by ongoing dispersal and effective migration (gene flow). We found that the genetic structure can largely be explained by a single colonization event following gradual deglaciation of the Pyrenees c. 10-15 000 years ago. Nuclear genetic...
Data from: Reproductive strategies and isolation-by-demography in a marine clonal plant along an eutrophication gradientSilvia Oliva, Javier Romero, Marta Pérez, Pablo Manent, Oriol Mascaró, Ester A. Serrão, Nelson Coelho & Filipe Alberto
Genetic diversity in clonal organisms includes two distinct components, 1) the diversity of genotypes or clones (i.e., genotypic richness) in a population, and 2) that of the alleles (i.e., allelic and gene diversity within populations, and differentiation between populations). We investigated how population differentiation and genotypic components are associated across a gradient of eutrophication in a clonal marine plant. To that end we combined direct measurements of sexual allocation (i.e., flower and seed counts) and...
Data from: Matrix composition and patch edges influence plant-herbivore interactions in marine landscapesJordi F. Pagès, Alessandro Gera, Javier Romero & Teresa Alcoverro
The functioning of ecosystems can be strongly driven by landscape attributes. Despite its importance, however, our understanding of how landscape influences ecosystem function derives mostly from species richness and abundance patterns, with few studies assessing how these relate to actual functional rates. We examined the influence of landscape attributes on the rates of herbivory in seagrass meadows, where herbivory has been identified as a key process structuring these relatively simple systems. The study was conducted...
Interbreeding of two species in the wild implies introgression of alleles from one species into the other only when admixed individuals survive and successfully backcross with the parental species. Consequently, estimating the proportion of first generation hybrids in a population may not inform about the evolutionary impact of hybridization. Samples obtained over a long time span may offer a more accurate view of the spreading of introgressed alleles in a species’ gene pool. Common quail...
Data from: Deciphering the adjustment between environment and life history in annuals: lessons from a geographically-explicit approach in Arabidopsis thalianaEsperanza Manzano-Piedras, Arnald Marcer, Carlos Alonso-Blanco & F. Xavier Picó
The role that different life-history traits may have in the process of adaptation caused by divergent selection can be assessed by using extensive collections of geographically-explicit populations. This is because adaptive phenotypic variation shifts gradually across space as a result of the geographic patterns of variation in environmental selective pressures. Hence, large-scale experiments are needed to identify relevant adaptive life-history traits as well as their relationships with putative selective agents. We conducted a field experiment...
