Jean-Baptiste Juhel, Virginie Marques, Rizkie Utama, Indra Vimono, Hagi Sugeha, Kadarusman Kadarusman, Christophe Cochet, Tony Dejean, Andrew Hoey, David Mouillot, Régis Hocdé & Laurent Pouyaud
Species inventories are the building blocks of our assessment of biodiversity patterns and human impact. Yet, historical inventories based on visual observations are often incomplete impairing subsequent analyses of ecological mechanisms, extinction risk and management success. Environmental DNA (eDNA) metabarcoding is an emerging tool that can provide wider biodiversity assessments than classical visual-based surveys. However, eDNA-based inventories remain limited by sampling effort and reference database incompleteness. In this study, we propose a new framework coupling...

Long distance migration is a major factor driving local adaptation at continental scale in a Pacific Salmon

Quentin Rougemont
Inferring the genomic basis of local adaptation is a long-standing goal of evolutionary biology. Beyond its fundamental evolutionary implications, such knowledge can guide conservation decisions for populations of conservation and management concern. Here, we investigated the genomic basis of local adaptation in the Coho salmon (Oncorhynchus kisutch) across its entirety North American range. We hypothesized that extensive spatial variation in environmental conditions and the species’ homing behavior may promote the establishment of local adaptation. We...

The quantitative genetics of fitness in a wild seabird

Maria Moiron, Anne Charmantier & Sandra Bouwhuis
Additive genetic variance in fitness is a prerequisite for adaptive evolution, as a trait must be genetically correlated with fitness to evolve. Despite its relevance, additive genetic variance in fitness has not often been estimated in nature. Here, we investigate additive genetic variance in lifetime and annual fitness components in common terns (Sterna hirundo). Using 28 years of data comprising ca. 6000 pedigreed individuals, we find that additive genetic variances in the Zero-inflated and Poisson...

Evidence for synergistic cumulative impacts of marking and hunting in a wildlife species.

Frédéric LeTourneux, Gilles Gauthier, Roger Pradel, Josée Lefebvre & Pierre Legagneux
Non-additive effects from multiple interacting stressors can have unpredictable outcomes on wildlife. Stressors that initially have negligible impacts may become significant if they act in synergy with novel stressors. Wildlife markers can be a source of physiological stress for animals and are ubiquitous in ecological studies. Their potential impacts on vital rates may vary over time, particularly when changing environments impose new stressors. In this study, we evaluated the temporal changes in the combined impact...

Script and data used in: A lot of convergence, a bit of divergence: environment and interspecific interactions shape body color patterns in Lissotriton newts

Thomas De Solan
Coexistence with related species poses evolutionary challenges to which populations may react in diverse ways. When exposed to similar environments, sympatric populations of two species may adopt similar phenotypic trait values. However, selection may also favor trait divergence as a way to reduce competition for resources or mates. The characteristics of external body parts, such as coloration and external morphology, are involved to varying degrees in intraspecific signaling as well as in the adaptation to...

Mandrill mothers associate with infants who look like their own offspring using phenotype matching

Marie Charpentier, Clémence Poirotte, Berta Roura-Torres, Paul Amblard-Rambert, Eric Willaume, Peter Kappeler, François Rousset & Julien Renoult
Behavioral discrimination of kin is a key process structuring social relationships in animals. In this study, we provide a first example of discrimination towards non-kin by third-parties through a mechanism of phenotype matching. In mandrills, we recently demonstrated increased facial resemblance among paternally-related juvenile and adult females indicating adaptive opportunities for paternal kin recognition. Here, we hypothesize that mothers use offspring’s facial resemblance with other infants to guide offspring’s social opportunities towards similarly-looking ones. Using...

Plasticity across levels: relating epigenomic, transcriptomic, and phenotypic responses to osmotic stress in a halotolerant microalga

Christelle Leung, Daphne Grulois & Luis-Miguel Chevin
Phenotypic plasticity, the ability of a given genotype to produce alternative phenotypes in response to its environment of development, is an important mechanism for coping with variable environments. While the mechanisms underlying phenotypic plasticity are diverse, their relative contributions need to be investigated quantitatively to better understand the evolvability of plasticity across biological levels. This requires relating plastic responses of the epigenome, transcriptome, and organismal phenotype, and investigating how they vary with the genotype. Here...

Root traits, root diameter distribution and soil parameters at the community level along a mediterranean successional gradient

Amandine Erktan, Catherine Roumet & Francois Munoz
The data correspond to average root traits at the community level, and parameters describing the root diameter distribution at the community level. Soil parameters are also indicated. All measurements were conducted along a successional gradient on roadsides in the Mediterranean region (Montpellier, France, 43°6′N, 3°8′E). These data were used in the article entitled "Dissecting fine root diameter distribution at the community level captures root morpological diversity" from Erktan, A., Roumet, C., Munoz, F (in press)...

Guadeloupe Snails Metacommunity

Maxime Dubart, Jean-Pierre Pointier, Philippe Jarne & Patrice David
Metacommunity structure reflects the interplay of various processes, including niche filtering, extinction/colonization, and interspecific interactions. Spatial patterns of species distributions are often analyzed to infer these processes. However, such inferences rely on often unrealistic equilibrium assumptions, and remain ambiguous, as different processes can produce similar patterns. Temporal data may improve these inferences. For example, stochastic species turnover may occur in local communities, while, on the long run, temporal changes are kept within limits set by...

Evolution of female colors in birds: The role of female cost of reproduction and paternal care

Amélie Fargevieille, Arnaud Grégoire, Doris Gomez & Claire Doutrelant
Female ornamentation is frequently observed in animal species and is sometimes found as more evolutionarily labile than male ornamentation. A complex array of factors may explain its presence and variation. Here we assessed the role of female cost of reproduction and paternal care. Both factors have been pinpointed as important by theoretical studies but have not been investigated yet in detail at the interspecific level. We worked on 133 species of North temperate Passeriformes bird...

Data from: Nitrogen availability and plant-plant interactions drive leaf silicon concentration in wheat genotypes

Félix De Tombeur, Taïna Lemoine, Cyrille Violle, Hélène Fréville, Sarah Thorne, Sue Hartley, Hans Lambers & Florian Fort
Estimating plasticity of leaf silicon (Si) in response to abiotic and biotic factors underpins our comprehension of plant defences and stress resistance in natural and agroecosystems. However, how nitrogen (N) addition and intraspecific plant-plant interactions affect Si accumulation remains unclear. We grew 19 durum wheat genotypes (Triticum turgidum ssp. durum) in pots, either alone, or in intra- or intergenotypic cultures of two individuals, and with or without N. Aboveground biomass, plant height and leaf [Si]...

This dataset contains fish eDNA sequences from the 12S mitochondrial gene. eDNA has been collected in 100 stations, 25 sites, in 5 tropical marine regions. Data collection was performed between 2017 and 2020. Raw sequences have been processed through a bioinformatic pipeline, merged, demultiplexed, dereplicated, clustered as OTUs (operational taxonomic units) and assigned to a taxa. The codes to analyse the data can be found at : https://github.com/virginiemarques/Global_eDNA. The data are used to study the...

Datafiles and code for Covas et al: The oxidative cost of helping and its minimisation in a cooperative breeder

Rita Covas, Sophie Lardy, Liliana Silva, Benjamin Rey, André Ferreira, Franck Theron, Arnaud Tognetti, Bruno Faivre & Claire Doutrelant
Cooperative actions are beneficial to the group, but presumably costly to the individual co-operators. In cooperatively breeding species, helping to raise young is thought to involve important energetic costs, which could lead to elevated exposure to reactive oxygen species, resulting in oxidative stress. However, identifying such costs can be difficult if individuals adjust their investment in helping in relation to environmental conditions or their own physiological condition. Experimental approaches are therefore required to quantify the...

Individual-based eco-evolutionary models for understanding adaptation in changing seas

Amanda Xuereb, Quentin Rougemont, Peter Tiffin, Huijie Xue & Megan Phifer-Rixey
As climate change threatens species’ persistence, predicting the potential for species to adapt to rapidly changing environments is imperative for the development of effective conservation strategies. Eco-evolutionary individual-based models (IBMs) can be useful tools for achieving this objective. We performed a literature review to identify studies that apply these tools in marine systems. Our survey suggested that this is an emerging area of research fueled in part by developments in modeling frameworks that allow simulation...
