Data from: Loss of connectivity among island-dwelling Peary caribou following sea ice decline

Deborah A. Jenkins, Nicolas Lecomte, James A. Schaefer, Steffen M. Olsen, Didier Swingedouw, Steeve D. Côté, Loïc Pellissier & Glenn Yannic
Global warming threatens to reduce population connectivity for terrestrial wildlife through significant and rapid changes to sea ice. Using genetic fingerprinting, we contrasted extant connectivity in island-dwelling Peary caribou in northern Canada with continental-migratory caribou. We next examined if sea-ice contractions in the last decades modulated population connectivity and explored the possible impact of future climate change on long-term connectivity among island caribou. We found a strong correlation between genetic and geodesic distances for both...

Data from: High-throughput microsatellite genotyping in ecology: improved accuracy, efficiency, standardization and success with low-quantity and degraded DNA

Marta De Barba, Christian Miquel, Stephane Lobreaux, Pierre Yves Quenette, Jon E. Swenson & Pierre Taberlet
Microsatellite markers have played a major role in ecological, evolutionary and conservation research during the past 20 years. However, technical constrains related to the use of capillary electrophoresis and a recent technological revolution that has impacted other marker types have brought to question the continued use of microsatellites for certain applications. We present a study for improving microsatellite genotyping in ecology using high-throughput sequencing (HTS). This approach entails selection of short markers suitable for HTS,...

Data from: Spatio-temporal monitoring of deep-sea communities using metabarcoding of sediment DNA and RNA

Magdalena Guardiola, Owen S. Wangensteen, Pierre Taberlet, Eric Coissac, María Jesús Uriz & Xavier Turon
We assessed spatio-temporal patterns of diversity in deep-sea sediment communities using metabarcoding. We chose a recently developed eukaryotic marker based on the v7 region of the 18S rRNA gene. Our study was performed in a submarine canyon and its adjacent slope in the Northwestern Mediterranean Sea, sampled along a depth gradient at two different seasons. We found a total of 5,569 molecular operational taxonomic units (MOTUs), dominated by Metazoa, Alveolata and Rhizaria. Among metazoans, Nematoda,...

Data from: Extreme climate events counteract the effects of climate and land-use changes in Alpine treelines

Ceres Barros, Maya Guéguen, Rolland Douzet, Marta Carboni, Isabelle Boulangeat, Niklaus E. Zimmermann, Tamara Münkemüller & Wilfried Thuiller
Climate change and extreme events, such as drought, threaten ecosystems world-wide and in particular mountain ecosystems, where species often live at their environmental tolerance limits. In the European Alps, plant communities are also influenced by land-use abandonment leading to woody encroachment of subalpine and alpine grasslands. In this study, we explored how the forest–grassland ecotone of Alpine tree lines will respond to gradual climate warming, drought events and land-use change in terms of forest expansion...
