Data from: Dendritic connectivity shapes spatial patterns of genetic diversity: a simulation-based study

Ivan Paz-Vinas & Simon Blanchet
Landscape features notoriously affect spatial patterns of biodiversity. For instance, in dendritic ecological networks (such as river basins), dendritic connectivity has been proposed to create unique spatial patterns of biodiversity. Here, we compared genetic datasets simulated under a lattice-like, a dendritic and a circular landscape to test the influence of dendritic connectivity on neutral genetic diversity. The circular landscape had a level of connectivity similar to that of the dendritic landscape, so as to isolate...

Data from: Evolutionary processes driving spatial patterns of intra-specific genetic diversity in river ecosystems

Ivan Paz-Viñas, Géraldine Loot, Virginie M. Stevens, Simon Blanchet & I. Paz-Vinas
Describing, understanding and predicting the spatial distribution of genetic diversity is a central issue in biological sciences. In river landscapes, it is generally predicted that neutral genetic diversity should increase downstream, but there have been few attempts to test and validate this assumption across taxonomic groups. Moreover, it is still unclear what are the evolutionary processes that may generate this apparent spatial pattern of diversity. Here, we quantitatively synthesized published results from diverse taxa living...

Data from: Deep-sea, deep-sequencing: metabarcoding extracellular DNA from sediments of marine canyons

Magdalena Guardiola, María Jesús Uriz, Pierre Taberlet, Eric Coissac, Owen Simon Wangensteen & Xavier Turon
Marine sediments are home to one of the richest species pools on Earth, but logistics and a dearth of taxonomic work-force hinders the knowledge of their biodiversity. We characterized α- and β-diversity of deep-sea assemblages from submarine canyons in the western Mediterranean using an environmental DNA metabarcoding. We used a new primer set targeting a short eukaryotic 18S sequence (ca. 110 bp). We applied a protocol designed to obtain extractions enriched in extracellular DNA from...

Data from: Sexual harassment induces a temporary fitness cost but does not constrain the acquisition of environmental information in fruit flies

Serafino Teseo, Liisa Veerus, Celine Moreno & Frédéric Mery
Across animals, sexual harassment induces fitness costs for females and males. However, little is known about the cognitive costs involved, i.e. whether it constrains learning processes, which could ultimately affect an individual's fitness. Here we evaluate the acquisition of environmental information in groups of fruit flies challenged with various levels of male sexual harassment. We show that, although high sexual harassment induces a temporary fitness cost for females, all fly groups of both sexes exhibit...

Data from: A new method for estimating locomotion type in large ground birds

Delphine Angst, Eric Buffetaut, Christophe Lecuyer & Romain Amiot
Estimating the locomotion type of fossil ground birds is necessary for a better understanding of their ecology. Until now, only one method has allowed us to estimate the locomotion of fossil ground birds, but its application is complicated in the majority of fossil cases because it requires data from the three bones from the same hindlimb of one individual. Here, we propose a new method using only the maximum length and minimum width of the...
