Chrystelle Delord, Gilles Lassalle, Adrien Oger, Dominique Barloy, Marie-Agnes Coutellec, Adline Delcamp, Guillaume Evanno, Clemence Genthon, Erwan Guichoux, Pierre-Yves Le Bail, Patricia Le Quilliec, Guillaume Longin, Olivier Lorvelec, Marie Massot, Elodie Reveillac, Raphaelle Rinaldo, Jean-Marc Roussel, Regis Vigouroux, Sophie Launey & Eric J. Petit
1.Multi‐species population genetics is an emerging field that provides insight relevant to conservation biology and community ecology. However, to date, this approach is limited to species with available genetic resources. The use of thousands of single nucleotide polymorphism (SNP) markers developed from recent genotyping‐by‐sequencing (GBS) technologies is a roadmap for the study of non‐model species, but remains cost prohibitive when several, distantly related species are involved. 2.We aimed to overcome this issue by using a...

Data from: The evolution of chemical defenses along invasion routes: Harmonia axyridis Pallas (Coccinellidae: Coleoptera) as a case study

Alexandra Magro, Felipe Ramon-Portugal, Benoît Facon, Christine Ducamp & Jean-Louis Hemptinne
The Evolution of Increased Competitive Ability (EICA) hypothesis (Blossey & Nötzold, 1995) postulates that escaping from coevolved enemies increases invaders fitness by energy reallocation from defenses and immunity to growth and reproduction. In this context, we evaluated the evidence of evolutionary change in invasive populations of Harmonia axyridis Pallas (Coccinellidae: Coleoptera). We measured egg defenses – cocktail of hydrocarbons on the egg’s surface flagging egg toxicity, and the concentration of the main alkaloid harmonine -...

Data from: Rapid divergence of genome architectures following the origin of an ectomycorrhizal symbiosis in the genus Amanita

Jaqueline Hess, Inger Skrede, Maryam Chaib De Mares, Matthieu Hainaut, Bernard Henrissat & Anne Pringle
Fungi are evolutionary shape shifters and adapt quickly to new environments. Ectomycorrhizal (EM) symbioses are mutualistic associations between fungi and plants and have evolved repeatedly and independently across the fungal tree of life, suggesting lineages frequently reconfigure genome content to take advantage of open ecological niches. To date analyses of genomic mechanisms facilitating EM symbioses have involved comparisons of distantly related species, but here, we use the genomes of three EM and two asymbiotic (AS)...

Data from: Plant functional groups mediate drought resistance and recovery in a multi-site grassland experiment

Kathleen A. Mackie, Michaela Zeiter, Juliette M.G. Bloor, Andreas Stampfli & Juliette M. G. Bloor
1. Climate change predictions suggest that summer droughts will become more intense and recurrent in Europe. While drought-induced reductions in grassland primary productivity are well documented, the drivers behind drought resistance (the capacity to withstand change) and recovery (the capacity for recovery of function) of above- and belowground biomass remain poorly understood. 2. Across eight grasslands differing in plant community productivity (CP) we investigated the effects of summer drought on plant and soil microbial variables,...

Data from: Leaf-cutter ants engineer large nitrous oxide hot spots in tropical forests

Fiona M. Soper, Benjamin W. Sullivan, Brooke B. Osborne, Alanna N. Shaw, Laurent Philippot & Cory C. Cleveland
Though tropical forest ecosystems are among the largest natural sources of the potent greenhouse gas nitrous oxide (N2O), the spatial distribution of emissions across landscapes is often poorly resolved. Leaf-cutter ants (LCA, Atta and Acromyrmex, Myrmicinae) are dominant herbivores throughout Central and South America and influence multiple aspects of forest structure and function. In particular, their foraging creates spatial heterogeneity by concentrating large quantities of organic matter (including nitrogen, N) from the surrounding canopy into...

Data from: Early Plasmodium-induced inflammation does not accelerate aging in mice

Cédric Lippens, Emmanuel Guivier, Sarah E. Reece, Aidan J. O'Donnell, Stephane Cornet, Bruno Faivre & Gabriele Sorci
Aging is associated with a decline of performance leading to reduced reproductive output and survival. While the antagonistic pleiotropy theory of aging has attracted considerable attention, the molecular/physiological functions underlying the early-life benefits/late-life costs paradigm remain elusive. We tested the hypothesis that while early activation of the inflammatory response confers benefits in terms of protection against infection, it also incurs costs in terms of reduced reproductive output at old age, and shortened longevity. We infected...

Data from: Genome-wide patterns of transposon proliferation in an evolutionary young hybrid fish

Stefan Dennenmoser, Fritz J. Sedlazeck, Michael C. Schatz, Janine Altmüller, Matthias Zytnicki & Arne W. Nolte
Hybridization can induce transposons to jump into new genomic positions, which may result in their accumulation across the genome. Alternatively, transposon copy numbers may increase through non-allelic (ectopic) homologous recombination in highly repetitive regions of the genome. The relative contribution of transposition bursts versus recombination-based mechanisms to evolutionary processes remains unclear because studies on transposon dynamics in natural systems are rare. We assessed the genome-wide distribution of transposon insertions in a young hybrid lineage (“invasive...

Data from: Facilitation promotes invasions in plant-associated microbial communities

Mei Li, Zhong Wei, Jianing Wang, Alexandre Jousset, Ville-Petri Friman, Yangchun Xu, Qirong Shen & Thomas Pommier
While several studies have established a positive correlation between community diversity and invasion resistance, it is less clear how species interactions within resident communities shape this process. Here, we experimentally tested how antagonistic and facilitative pairwise interactions within resident model microbial communities predict invasion by the plant–pathogenic bacterium Ralstonia solanacearum. We found that facilitative resident community interactions promoted and antagonistic interactions suppressed invasions both in the lab and in the tomato plant rhizosphere. Crucially, pairwise...

Data from: Partitioning genetic and species diversity refines our understanding of species-genetic diversity relationships

Vera W Pfeiffer, Brett M Ford, Johann Housset, Audrey McCombs, José L Blanco-Pastor, Nicolas Gouin, Stephanie Manel & Angéline Bertin
Illuminating the origin of species-genetic diversity correlations (SGDCs) is a challenging task that has sparked a lot of interest. Genetic and species diversity are comprised by components that respond differently to the same ecological processes. Thus, it can be useful to partition species and genetic diversity into their different components to infer the mechanisms behind SGDCs. In this study, we applied such an approach using a high-elevation Andean wetland system, where previous evidence identified neutral...

Data from: Plasticity in leaf litter traits partly mitigates the impact of thinning on forest floor carbon cycling

Ludovic Henneron, Matthieu Chauvat, Frédéric Archaux, Marthe Akpa-Vinceslas, Fabrice Bureau, Yann Dumas, Francois Ningre, Claudine Richter, Philippe Balandier & Michael Aubert
1. Reducing stand density by thinning intensification has been emphasized as an efficient strategy of forest adaptation to climate change as it improves stand resistance to drought. Yet, it is still unclear how it could affect litter C cycling processes. Recent evidence indicates that the plasticity of an oak tree species can lead to a decline in its leaf litter quality and decomposability following thinning. The consequences for litter decomposition and forest floor C storage...

Data from: Biophysical dependences among functional wood traits

Jana Dlouhá, Tancrède Alméras, Jacques Beauchêne, Bruno Clair & Meriem Fournier
1. Wood properties and especially wood density have been used as functional traits organized along major axes of species life history and strategy. Beyond statistical analyses, a better mechanistic understanding of relationships among wood traits is essential for ecologically relevant interpretation of wood trait variations. 2. A set of theoretical relationships mechanistically linking wood basic density with some other wood traits is derived from cellular material physics. These theoretical models picture basic physical constraints and...

Data from: Are assortative mating and genital divergence driven by reinforcement?

Johan Hollander, Mauricio Montaño-Rendón, Giuseppe Bianco, Xi Yang, Anja M. Westram, Ludovic Duvaux, David G. Reid & Roger K. Butlin
The evolution of assortative mating is a key part of the speciation process. Stronger assortment, or greater divergence in mating traits, between species pairs with overlapping ranges is commonly observed, but possible causes of this pattern of reproductive character displacement are difficult to distinguish. We use a multidisciplinary approach to provide a rare example where it is possible to distinguish among hypotheses concerning the evolution of reproductive character displacement. We build on an earlier comparative...

Data from: Nest height is affected by lamppost lighting proximity in addition to nestbox size in urban great tits

Marie-Jeanne Holveck, Arnaud Gregoire, Claire Doutrelant & Marcel M. Lambrechts
Both natural and artificial light have proximate influences on many aspects of avian biology, physiology and behaviour. To date artificial light at night is mostly considered as being a nuisance disrupting for instance sleep and reproduction of diurnal species. Here, we investigate if lamppost night lighting affects cavity-nesting bird species inside their breeding cavity. Nest height in secondary cavity-nesting species is the result of trade-offs between several selective forces. Predation is the prevailing force leading...

Data from: Using terrestrial laser scanning data to estimate large tropical trees biomass and calibrate allometric models: a comparison with traditional destructive approach

Stéphane Momo Takoudjou, Pierre Ploton, Bonaventure Sonké, Jan Hackenberg, Sébastien Griffon, Francois De Coligny, Narcisse Guy Kamdem, Moses Libalah, Gislain Mofack, Gilles Le Moguédec, Raphaël Pélissier & Nicolas Barbier
1. Calibration of local, regional or global allometric equations to estimate biomass at the tree level constitutes a significant burden on projects aiming at reducing Carbon emissions from forest degradation and deforestation. The objective of this contribution is to assess the precision and accuracy of Terrestrial Laser Scanning (TLS) for estimating volumes and above-ground biomass (AGB) of the woody parts of tropical trees, and for the calibration of allometric models. 2. We used a destructive...

Data from: Parasitic versus nutritional regulation of natural fish populations

Amélie Frantz, Marie-Elodie Perga & Jean Guillard
1. Although parasites are expected to affect their host’s fitness, quantitative proof for impacts of parasitism on wild populations is hampered by confounding environmental factors, including dietary resource. 2. Herein, we evaluate whether the physiological conditions of European perch (Perca fluviatilis) in three large peri-alpine lakes (Geneva, Annecy, and Bourget) depend on (a) the nutritional status of the juvenile fish, as revealed by stable isotope and fatty acid compositions, (b) the prevalence of the tapeworm...

Data from: Leaf hydraulic parameters are more plastic in species that experience a wider range of leaf water potentials

Daniel M. Johnson, Z. Carter Berry, Kathyrn V. Baker, Duncan D. Smith, Katherine A. McCulloh, Jean-Christophe Domec & Kathryn V. Baker
1. Many plant species experience large differences in soil moisture availability within a season, potentially leading to a wide range of leaf water potentials (ΨLEAF). In order to decrease the risk of leaf dehydration, among species, there is a continuum ranging from strict control (isohydry) to little control (anisohydry) of minimum ΨLEAF. 2. In central Texas USA, species are exposed to a range of soil moisture from wet springs to hot, dry summers. There are...

Data from: It’s all about connections: hubs and invasion in habitat networks

Thibaut Morel-Journel, Claire Rais Assa, Ludovic Mailleret & Elodie Vercken
During the early stages of invasion, the interaction between the features of the invaded landscape, notably its spatial structure, and the internal dynamics of an introduced population, has a crucial impact on establishment and spread. By approximating introduction areas as networks of patches linked by dispersal, we characterized their spatial structure with specific metrics and tested their impact on two essential steps of the invasion process: establishment and spread. By combining simulations with experimental introductions...

Data from: Integrating encounter theory with decision analysis to evaluate collision risk and determine optimal protection zones for wildlife

Bradley J. Udell, Julien Martin, , Mathieu Bonneau, Holly Edwards, Timothy A. Gowan, Stacie K. Hardy, Eliezer Gurarie, Charles Calleson, Charles J. Deutsch, Robert J. Fletcher & Charles S. Calleson
1. Better understanding human-wildlife interactions and their links with management can help improve the design of wildlife protection zones. One important example is the problem of wildlife collisions with vehicles or human-built structures (e.g. power lines, wind farms). In fact, collisions between marine wildlife and watercraft are among the major threats faced by several endangered species of marine mammals. Natural resource managers are therefore interested in finding cost-effective solutions to mitigate these threats. 2. We...

Data from: Tree, sex and size: ecological determinants of male versus female fecundity in three Fagus sylvatica stands

Sylvie Oddou-Muratorio, Julie Gauzere, Aurore Bontemps, Jean-François Rey & Etienne K. Klein
Inter-individual variation in fecundities has major consequences on population evolutionary potential, through genetic drift and selection. Using two spatially explicit mating models that analyze the genotypes of seeds and seedlings, we investigated the variation of male and female fecundities within and among three European beech (Fagus sylvatica) stands situated along an elevational gradient. Female and male individual fecundity distributions were both skewed in this monoecious species, and we found a higher variance in female as...

Data from: Insular woody daisies (Argyranthemum , Asteraceae) are more resistant to drought-induced hydraulic failure than their herbaceous relatives

Larissa C. Doria, Diego S. Podadera, Marcelino Del Arco, Thibaud Chauvin, Erik Smets, Sylvain Delzon & Frederic Lens
1. Insular woodiness refers to the evolutionary transition from herbaceousness towards derived woodiness on (sub)tropical islands, and leads to island floras that have a higher proportion of woody species compared to floras of nearby continents. 2. Several hypotheses have tried to explain insular woodiness since Darwin’s original observations, but experimental evidence why plants became woody on islands is scarce at best. 3. Here, we combine experimental measurements of hydraulic failure in stems (as a proxy...

Data from: A nuclear DNA barcode for eastern North American oaks and application to a study of hybridization in an Arboretum setting

Elisabeth Fitzek, Adline Delcamp, Erwan Guichouc, Marlene Hahn, Matthew Lobdell, Andrew L. Hipp & Erwan Guichoux
DNA barcoding has proved difficult in a number of woody plant genera, including the ecologically important oak genus Quercus. In this study, we utilized restriction-site associated DNA sequencing (RAD-seq) to develop an economical single-nucleotide polymorphism (SNP) DNA barcoding system that suffices to distinguish eight common, sympatric eastern North American white oak species. Two de novo clustering pipelines, PyRAD and Stacks, were used in combination with post-clustering bioinformatic tools to generate a list of 291 potential...

Data from: Plant demographic and functional responses to management intensification: a long-term study in a Mediterranean rangeland

Eric Garnier, Adeline Fayolle, Marie-Laure Navas, Christian Damgaard, Pablo Cruz, Daniel Hubert, Jean Richarte, Paul Autran, Corentin Leurent & Cyrille Violle
1. Understanding how functional traits, which are key for plant functioning, relate to demographic parameters of populations is central to tackle pending issues in plant ecology such as the forecast of the fate of populations and communities in a changing world, the quantification of community assembly processes or the improvement of species distribution models. We addressed this question in the case of species from a Mediterranean rangeland of southern France. 2. Changes in species abundance...

Data from: Climate-warming alters the structure of farmland tri-trophic ecological networks and reduces crop yield

Stephane A. P. Derocles, David H. Lunt, Sophie C. F. Berthe, Paul C. Nichols, Ellen D. Moss & Darren M. Evans
It is unclear how sustained increases in temperature and changes in precipitation, as a result of climate-change, will affect crops and their interactions with agricultural weeds, insect pests and predators, due to the difficulties in quantifying changes in such complex relationships. We simulated the combined effects of increasing temperature (by 1.4°C over a growing season) and applying additional rainwater (10% extra per week) using a replicated, randomized block experiment within a wheat crop. We examined...
