IS-mediated mutations both promote and constrain evolvability during a long-term experiment with bacteria

Jessika Consuegra, Joël Gaffé, Richard E. Lenski, Thomas Hindre, Jeffrey E. Barrick, Olivier Tenaillon & Dominique Schneider
The long-term dynamics of IS elements and their effects on bacteria are poorly understood, including whether they are primarily genomic parasites or important drivers of adaptation by natural selection. Here, we investigate the dynamics of IS elements and their contribution to genomic evolution and fitness during a long-term experiment with Escherichia coli. This data set includes the Rmd file to analyze the genomic and metagenomic data (Tenaillon et al. 2016 and Good et al. 2017)...

Adult survival in migratory caribou is negatively associated with MHC functional diversity

Marianne Gagnon, Glenn Yannic, Frédéric Boyer & Steeve Côté
The genes of the major histocompatibility complex (MHC) are involved in acquired, specific immunity in vertebrates. Yet, only a few studies have investigated the fitness consequences of MHC gene diversity in wild populations. Here, we looked at the association between annual survival and body mass and MHC-DRB exon 2 (MHC-DRB) genetic diversity, obtained from high-throughput sequencing, in two declining migratory caribou (Rangifer tarandus) herds. To disentangle the potential direct and general effects of MHC-DRB genetic...

Vicente García-Navas & Wilfried Thuiller
Abundance data on breeding birds from the French Breeding Bird Survey (Suivi Temporel des Oiseaux Communs, STOC), for the period 2002-2014. The dataset comprises 7,115 bird communities. Only 107 common species were included in the study.

Climate associated genetic variation in Fagus sylvatica and potential responses to climate change in the French Alps

Thibaut Capblancq, Xavier Morin, Maya Gueguen, Julien Renaud, Stéphane Lobreaux & Eric Bazin
Local adaptation patterns have been found in many plants and animals, highlighting the genetic heterogeneity of species along their range of distribution. In the next decades, global warming is predicted to induce a change in the selective pressures that drive this adaptive variation, forcing a reshuffling of the underlying adaptive allele distributions. For species with low dispersion capacity and long generation time such as trees, the rapidity of the change could imped the migration of...

Ecological specialization and niche overlap of subterranean rodents inferred from DNA metabarcoding diet analysis

Carla Martins Lopes, Marta De Barba, Frédéric Boyer, Céline Mercier, Daniel Galiano, Bruno Busnello Kubiak, Renan Maestri, Pedro Joel Silva Da Silva Filho, Ludovic Gielly, Eric Coissac, Thales Renato Ochotorena De Freitas & Pierre Taberlet
Knowledge of how animal species use food resources available in the environment increases our understanding of ecological processes. However, obtaining this information using traditional methods is a hard task for species feeding on a large variety of food items in highly diverse environments. We amplified the DNA of plants for 306 scat and 40 soil samples, and applied an eDNA metabarcoding approach to investigate food preferences, degree of diet specialization and diet overlap of seven...

Data from: Landscape does matter: disentangling founder effects from natural and human-aided post-introduction dispersal during an ongoing biological invasion

Stéphanie Sherpa, Julien Renaud, Maya Guéguen, Gilles Besnard, Loic Mouyon, Delphine Rey & Laurence Després
Environmental features impacting the spread of invasive species after introduction can be assessed using population genetic structure as a quantitative estimation of effective dispersal at the landscape scale. However, in the case of an ongoing biological invasion, deciphering whether genetic structure represents landscape connectivity or founder effects is particularly challenging. We examined the modes of dispersal (natural and human-aided) and the factors (landscape or founders history) shaping genetic structure in range edge invasive populations of...

Data from: Variability of the atmospheric PM10 microbiome in three climatic regions of France

Abdoulaye Samaké, Jean M. F. Martins, Aurélie Bonin, Pierre Taberlet, Sébastien Conil, Olivier Favez, Alexandre Thomasson, Benjamin Chazeau, Nicolas Marchand, Jean-Luc Jaffrezo & Gaëlle Uzu
Air pollution is a major public-health concern and it is recognized that particulate matter causes damage to human health through oxidative-stress, being responsible for several million premature deaths worldwide each year. Recent findings showed that, airborne microorganisms/spores can modulate aerosol toxicity by altering the oxidative potential of PM10. Primary Biogenic Organic Aerosols (PBOA) appears to be produced by only few genera of microorganisms, emitted by surrounding vegetation in the case of a regionally-homogeneous field site....

Greenland Marine-Terminating Glacier Retreat Data

Michael Wood, Eric Rignot, Anders Bjørk, Michiel Van En Broeke, Ian Fenty, Dimitris Menemenlis, Mathieu Morlighem, Jeremie Mouginot, Brice Noël, Bernd Scheuchl, Joshua Willis, Hong Zhang, Lu An, Cilan Cai, Emily Kane, Romain Millan & Isabella Velicogna
The thinning, acceleration, and retreat of Greenland glaciers since the mid-1990s has been attributed to the enhanced intrusion of warm Atlantic Waters (AW) into fjords, but this assertion has not been quantitatively tested on a Greenland-wide basis or included in numerical models. Here, we investigate how AW influenced the retreat of 226 marine-terminating glaciers by combining ocean modeling, remote sensing, and in-situ observations. We identify 74 glaciers standing in deep fjords with warm AW that...

Early-wilted forest following the Central European 2018 extreme drought

Philipp Brun, Achilleas Psomas, Christian Ginzler, Wilfried Thuiller, Massimiliano Zappa & Niklaus E. Zimmermann
During the summer of 2018, Central Europe experienced the most extreme drought and heat wave on record, leading to widespread early leaf-shedding and die-offs in forest trees. We quantified such early-wilting responses by associating Sentinel-2 time-series statistics of the Normalized Difference Vegetation Index with visually classified orthophotos, using a random forest classifier. The predictions of our classifier achieved a high accuracy of 0.90 ±0.014 and estimated the area of affected forest at 21’500 ±2800 km2....

Impact of calving dynamics on Kangilernata Sermia, Greenland

Emily Kane, Eric Rignot, Jeremie Mouginot, Romain Millan, Xin Li, Bernd Scheuchl & Mark Fahnestock
Iceberg calving is a major component of glacier mass ablation that is not well understood due to a lack of detailed temporal and spatial observations. Here, we measure glacier speed and surface elevation at 3-minute interval, 5 meter spacing, using a portable radar interferometer at Kangilernata Sermia, Greenland in July 2016. We detect a 20% diurnal variation in glacier speed peaking at high spring tide when basal drag is high and lowering at neap tide....

Sequencing data from: High levels of primary biogenic organic aerosols are driven by only a few plant-associated microbial taxa

Abdoulaye Samaké, Aurélie Bonin, Jean-Luc Jaffrezo, Pierre Taberlet, Samuël Weber, Gaëlle UZU, Véronique Jacob, Sébastien Conil & Jean M. F. Martins
Primary biogenic organic aerosols (PBOA) represent a major fraction of coarse organic matter (OM) in air. Despite their implication in many atmospheric processes and human health problems, we surprisingly know little about PBOA characteristics (i.e., composition, dominant sources, and contribution to airborne-particles). In addition, specific primary sugar compounds (SCs) are generally used as markers of PBOA associated with bacteria and fungi but our knowledge of microbial communities associated with atmospheric particulate matter (PM) remains incomplete....

Forest inventory data from Finland and Sweden for: Demographic performance of European tree species at their hot and cold climatic edges, plus ancillary climate data

Sophia Ratcliffe, Jonas Dahlgren, Aleksi Lehtonen, Christian Wirth, Paloma Ruiz-Benito, Miguel A. Zavala, Gerald Kaendler, Raisa Mäkipää & Georges Kunstler
1. Species range limits are thought to result from a decline in demographic performance at range edges. However, recent studies reporting contradictory patterns in species demographic performance at their edges cast doubt on our ability to predict climate change demographic impacts. To understand these inconsistent demographic responses at the edges, we need to shift the focus from geographic to climatic edges and analyse how species responses vary with climatic constraints at the edge and species’...

Rainfall continentality, via the winter GAMS angle, provides a new dimension to biogeographical distributions in the Western United States

Richard Michalet, Philippe Choler, Ragan M. Callaway & Thomas G. Whitham
Aim: Drought stress, and its effects on the biogeography of vegetation, has focused primarily on water availability during the growing season, thus focusing primarly on summer. However, variation in rainfall continentality (i.e., the continental interior being insulated from oceanic influences) can produce striking vegetation differences. We aim to disentangle summer water balance from the influence of rainfall continentality on winter rainfall, to better understand how climate regulated the distributions of woody plants in the Western...

Data from: Tetra-EU 1.0: a species-level trophic meta-web of European tetrapods

Luigi Maiorano, Alessandro Montemaggiori, Gentile Francesco Ficetola, Louise O'Connor & Wilfried Thuiller
Motivation Documenting potential interactions between species represents a major step to understand and predict the spatial and temporal structure of multi-trophic communities and their functioning. The metaweb concept summarises the potential trophic (and non-trophic) interactions in a given species-pool. As such, it generalises the regional species-pool of community ecology by incorporating the potential relationships between species from different trophic levels along with their functional characteristics. However, while this concept is theoretically very attractive, it has...

Global gradients in intraspecific variation in vegetative and floral traits are partially associated with climate and species richness

Jonas Kuppler, Cécile H. Albert, Gregory M. Ames, W. Scott Armbruster, Gerhard Boenisch, Florian C. Boucher, Diane R. Campbell, Liedson T. Carneiro, Eduardo Chacón-Madrigal, Brian J. Enquist, Carlos R. Fonseca, José M. Gómez, Antoine Guisan, Pedro Higuchi, Dirk N. Karger, Jens Kattge, Michael Kleyer, Nathan J. B. Kraft, Anne-Amélie C. Larue-Kontić, Amparo Lázaro, Martin Lechleitner, Deirdre Loughnan, Vanessa Minden, Ülo Niinemets, Gerhard E. Overbeck … & Robert R. Junker
Aim Intraspecific trait variation (ITV) within natural plant communities can be large, influencing local ecological processes and dynamics. Here, we shed light on how ITV in vegetative and floral traits responds to large-scale abiotic and biotic gradients (i.e. climate and species richness). Specifically, we tested if associations of ITV with temperature, precipitation and species richness were consistent with any of from four hypotheses relating to stress-tolerance and competition. Furthermore, we estimated the degree of correlation...

Cold adaptation across the elevation gradient in an alpine butterfly species complex

Gabriel Nève & Laurence Després
1. Temperature acts as a major factor on the timing of activity and behaviour in butterflies, and it might represent a key driver of butterfly diversification along elevation gradients. Under this hypothesis, local adaptation should be found along the elevation gradient, with butterflies from high elevation populations able to remain active at lower ambient temperature than those from low elevation. 2. We recorded the warming-up rate and the thoracic temperature at take-off of 123 individuals...

Generalist plants are more competitive and more functionally similar to each other than specialist plants: insights from network analyses

Pierre Denelle, Cyrille Violle & François Munoz
Aim: Ecological specialization is a property of species associated with the variety of contexts they occupy. Identifying the mechanisms influencing specialization is critical to understand species coexistence and biodiversity patterns. However, the functional attributes leading to specialization are still unknown. Similarly, there is contrasting evidence between the level of specialization and local abundance of species. We ask whether plant specialist and generalist species (i) are associated with distinct functional profiles, using core plant functional traits...

Examining the link between relaxed predation and bird colouration on islands

Louis Bliard, Matthieu Paquet, Aloïs Robert, Paul Dufour, Julien Renoult, Arnaud Gregoire, Pierre-Andre Crochet, Rita Covas & Claire Doutrelant
Insular ecosystems share analogous ecological conditions, leading to patterns of convergent evolution that are collectively termed the “island syndrome”. In birds, part of this syndrome is a tendency for a duller plumage, possibly as a result of relaxed sexual selection and the reduced need for species recognition. Despite this global pattern, some insular species display a more colourful plumage than their mainland relatives, but why this occurs has remained unexplained. Here, we examine the hypothesis...
