Data from: Improving PCR detection of prey in molecular diet studies: importance of group-specific primer set selection and extraction protocol performancesDiane Zarzoso-Lacoste, Emmanuel Corse & Eric Vidal
While morphological identification of prey remains in feces of predators is the method most commonly used to study trophic interactions, many studies indicate that this method does not detect all consumed prey. Polymerase Chain Reaction based methods are increasingly used to detect prey DNA in the predator food bolus and have proved themselves efficient, with high accuracy. When studying complex diet samples, the extraction of total DNA is a critical step, as PCR inhibitors may...
Data from: Breakdown of phylogenetic signal: a survey of microsatellite densities in 454 shotgun sequences from 154 non model eukaryote speciesEmese Meglécz, Gabriel Nève, Ed Biffin & Michael G. Gardner
Microsatellites are ubiquitous in Eukaryotic genomes. A more complete understanding of their origin and spread can be gained from a comparison of their distribution within a phylogenetic context. Although information for model species is accumulating rapidly, it is insufficient due to a lack of species depth, thus intragroup variation is necessarily ignored. As such, apparent differences between groups may be overinflated and generalizations cannot be inferred until an analysis of the variation that exists within...
Data from: Forecasting changes in population genetic structure of alpine plants in response to global warmingFlora Jay, Stéphanie Manel, Nadir Alvarez, Eric Y. Durand, Wilfried Thuiller, Rolf Holderegger, Pierre Taberlet & Olivier François
Species range shifts in response to climate and land use change are commonly forecasted with species distribution models based on species occurrence or abundance data. Although appealing, these models ignore the genetic structure of species, and the fact that different populations might respond in different ways due to adaptation to their environment. Here, we introduced ancestry distribution models, i.e., statistical models of the spatial distribution of ancestry proportions, for forecasting intra-specific changes based on genetic...
Data from: Mapping habitats in a marine reserve showed how a 30-year trophic cascade altered ecosystem structureKévin Leleu, Brice Remy-Zephir, Roger Grace & Mark John Costello
Time-series studies have reported trophic cascades in land, freshwater and marine environments in many geographic areas. However, the spatial extent of habitats, a key metric of ecosystem structure, has not been mapped in these studies. Marine reserves can provide experimental, before-after and inside-outside (control-impacted), situations for assessing the impact of fishing on ecosystems. We mapped seabed habitats and their associated communities (biotopes) in New Zealand’s oldest marine reserve for comparison with pre-reserve maps created about...
