Genomic shifts, phenotypic clines and fitness costs associated with cold-tolerance in the Asian tiger mosquitoStéphanie Sherpa, Jordan Tutagata, Thierry Gaude, Frédéric Laporte, Shinji Kasai, Intan Ishak, Xiang Guo, Jiyeong Shin, Sébastien Boyer, Sébastien Marcombe, Theeraphap Chareonviriyaphap, Jean-Philippe David, Xiao-Guang Chen, Xiaohong Zhou & Laurence Després
Climatic variation is a key driver of genetic differentiation and phenotypic traits evolution, and local adaptation to temperature is expected in widespread species. We investigated phenotypic and genomic changes in the native range of the Asian tiger mosquito, Aedes albopictus. We first refine the phylogeographic structure based on genome-wide regions (1,901 double-digest restriction-site associated DNA single nucleotide polymophisms [ddRAD SNPs]) from 41 populations. We then explore the patterns of cold adaptation using phenotypic traits measured...
The chamois Rupicapra spp. is the most abundant mountain ungulate of Europe and the Near East, where it occurs as two species, the Northern chamois R. rupicapra and the Southern chamois R. pyrenaica. Here, we provide a state-of-the-art overview of research trends and the most challenging issues in chamois research and conservation, focusing on taxonomy and systematics, genetics, life history, ecology and behavior, physiology and disease, management, and conservation. Research on Rupicapra has a longstanding...
Focal vs. faecal: Seasonal variation in the diet of wild vervet monkeys from observational and DNA metabarcoding dataLoic Brun, Judith Schneider, Eduard Mas-Carrió, Pooja Dongre, Pierre Taberlet, Erica Van De Waal & Luca Fumagalli
1. Assessing the diet of wild animals reveals valuable information about their ecology and trophic relationships that may help elucidate dynamic interactions in ecosystems and forecast responses to environmental changes. 2. Advances in molecular biology provide valuable research tools in this field. However, comparative empirical research is still required to highlight strengths and potential biases of different approaches. Therefore, this study compares environmental DNA and observational methods for the same study population and sampling duration....
Ecological niche differences are necessary for stable species coexistence but are often difficult to discern. Models of dietary niche differentiation in large mammalian herbivores invoke the quality, quantity, and spatiotemporal distribution of plant tissues and growth-forms but are agnostic towards food-plant species identity. Empirical support for these models is variable, suggesting that additional mechanisms of resource partitioning may be important in sustaining large-herbivore diversity in African savannas. We used DNA metabarcoding to conduct a taxonomically...
Outside controlled experimental plots, the impact of community attributes on primary productivity has rarely been compared to that of individual species. Here, we identified plant species of high importance for productivity (key species) in >29,000 diverse grassland communities in the European Alps, and compared their effects with those of community-level measures of functional composition (weighted means, variances, skewness, and kurtosis). After accounting for the environment, the five most important key species jointly explained more deviance...
The dataset consists of 14 selected lines of radar data, collected from the Little Dome C region close to Concordia Station in East Antarctica. The data were collected in austral field seasons 2016-17, and 2017-18, from within the search region for the planned European project Beyond EPICA - Oldest Ice, an EU-funded 10-nation consortium project to drill an ice core that spans up to 1.5 million years of climate and atmospheric history. Radar lines were...
High resolution ancient sedimentary DNA shows that alpine plant diversity is associated with human land use and climate changeSandra Garcés-Pastor, Eric Coissac, Sébastien Lavergne, Christoph Schwörer, Jean-Paul Theurillat, Peter D. Heintzman, Owen Wangensteen, Willy Tinner, Fabian Rey, Martina Lia Heer, Astrid Rutzer, Kevin Walsh, Youri Lammers, Antony G. Brown, Tomasz Goslar, Dilli P. Rijal, Dirk N. Karger, Loïc Pellissier, Group PhyloAlps Consortium, Oliver Heiri & Inger Greve Alsos
The European Alps are highly rich in species, but their future may be threatened by ongoing changes in human land use and climate. Here, we reconstructed vegetation, temperature, human impact and livestock over the past ~12,000 years from Lake Sulsseewli, based on sedimentary ancient plant and mammal DNA, pollen, spores, chironomids, and microcharcoal. We assembled a highly-complete local DNA reference library (PhyloAlps, 3,923 plant taxa), and used this to obtain an exceptionally rich sedaDNA record...
Data from: Above- and belowground drivers of intraspecific trait variability across subcontinental gradients for five ubiquitous forest plants in North AmericaIsabelle Aubin, Françoise Cardou, Alison Munson, Madhur Anand, André Arsenault, F. Wayne Bell, Yves Bergeron, Isabelle Boulangeat, Sylvain Delagrange, Nicole J. Fenton, Dominique Gravel, François Hébert, Jill Johnstone, S. Ellen Macdonald, Azim Mallik, Anne C.S. McIntosh, Jennie R. McLaren, Christian Messier, Dave Morris, Bill Shipley, Luc Sirois, Nelson Thiffault, Laura Boisvert-Marsh & Bright B. Kumordzi
Intraspecific trait variability (ITV) provides the material for species adaptation to environmental changes. To advance our understanding of how ITV can contribute to species adaptation to a wide range of environmental conditions, we studied five widespread understory forest species exposed to both continental-scale climate gradients, and local soil and disturbance gradients. We investigated the environmental drivers of between-site leaf and root trait variation, and tested whether higher between-site ITV was associated with increased trait sensitivity...
The European Fault-Source Model 2020 (EFSM20) was initially compiled in the framework of the EU Project SERA, Work Package 25, JRA3. EFSM20 includes only faults deemed capable of generating earthquakes of magnitude equal to or larger than 5.5 and aims at ensuring a harmonized input for use in ground-shaking hazard assessment in the Euro-Mediterranean area, namely the European Seismic Hazard Model 2020 (ESHM20). The EFSM20 database is hosted, maintained, and distributed by INGV through the...
Unique and shared effects of local and catchment predictors over distribution of hyporheic organisms: does the valley rule the stream?Samuel Mouron, David Eme, Arnaud Bellec, Mélanie Bertrand, Stefano Mammola, Fréderic Liébault, Christophe J. Douady & Florian Malard
This dataset describe the distribution of two hyporheic crustacean taxa (Bogidiellidae, Amphipoda and Anthuridae, Isopoda) in streams of New Caledonia. We sampled the two taxa at 228 sites. At each site, we quantified nine local predictors related to habitat area and stability, sediment metabolism and water origin, and eight catchment predictors related to geology, area, primary productivity, land use and specific discharge.
Estimates for recombination coefficients from time-resolved luminescence - local and global approach explained on bulk gallium nitride: numerical dataKonrad Sakowski, Lukasz Borowik, Névine Rochat, Pawel Kempisty, Pawel Strak, Natalia Majewska, Sebastian Mahlik, Kamil Koroński, Tomasz Sochacki, Jacek Piechota, Marc Fouchier, Agata Kaminska & Stanislaw Krukowski
This is a dataset of numerical data for experimental results of time-resolved cathodoluminescence and time-resolved photoluminescence of a HVPE-grown GaN sample and numerical fits used to estimate ABC recombination constants of this sample.The examined GaN sample was prepared from a bulk crystal grown by Halide Vapor Phase Epitaxy (HVPE) method. In order to obtain a thick crystal, a few consecutive HVPE processes were performed. An ammonothermally-grown GaN seed of a very high structural quality, with...
Dual-tasking reveals the attentional cost of resolving sensory conflict induced by perturbed optic flow during treadmill walkingValentin Lana, Julien Frère, Vincent Cabibel, Tristan Reguème, Nicolas Lefèvre & Leslie M. Decker
The precise role of cognitive control on optic flow processing during locomotion has been rarely investigated. Therefore, this study aimed to determine whether coping with unreliable visual inputs during walking requires attention and cognitive resources. Twenty-four healthy young adults walked on an instrumented treadmill in a virtual environment under two optic flow (OF) conditions: normal (congruent) and perturbed (continuous mediolateral pseudo-random oscillations). Each condition was performed under single-task and dual-task conditions of increasing difficulty (1-,...
