Land use changes threaten bird taxonomic and functional diversity across the Mediterranean basin: a spatial analysis to prioritize monitoring for conservation

Johanna Fusco, Walker Emily, Papaïx Julien, Debolini Marta, Bondeau Alberte & Barnagaud Jean-Yves
Land use changes rank among the highest threats to biodiversity, but assessment of their ecological impact is impaired by data paucity in vast regions of the world. For birds, land use changes may mean habitat loss or fragmentation, changes in resource availability and disruption of biotic interactions or dispersal pathways. As a result, avian population sizes and assemblage diversity decline in areas subjected to urbanization, agricultural intensification and land abandonment worldwide. This threat is especially...

Pathogen-mediated selection favours the maintenance of innate immunity gene polymorphism in a widespread wild ungulate

Erwan Quéméré, Pauline Hessenauer, Maxime Galan, Marie Fernandez, Joël Merlet, Yannick Chaval, Nicolas Morellet, Hélène Verheyden, Emmanuelle Gilot-Fromont & Nathalie Charbonnel
Toll-like Receptors (TLR) play a central role in recognition and host frontline defence against a wide range of pathogens. A number of recent studies have shown that TLR genes (Tlrs) often exhibit large polymorphism in natural populations. Yet, there is little knowledge on how this polymorphism is maintained and how it influences disease susceptibility in the wild. In previous work, we showed that some Tlrs exhibit similarly high levels of genetic diversity as genes of...

Adaptation to drought is coupled with slow growth, but independent from phenology in marginal silver fir (Abies alba Mill.) populations

Katalin Csillery, Nina Buchmann & Bruno Fady
Drought is one of the most important selection pressures for forest trees in the context of climate change. Yet, the different evolutionary mechanisms, and their environmental drivers, by which certain populations become more drought tolerant than others is still little understood. We studied adaptation to drought in 16 silver fir (Abies alba Mill.) populations from the French Mediterranean Alps by combining observations on seedlings from a large scale greenhouse experiment (N=8199) and on adult tress...

Quantifying heritability and estimating evolutionary potential in the wild when individuals that share genes also share environments

Laura Gervais, Nicolas Morellet, Ingrid David, Mark Hewison, Denis Reale, Michel Goulard, Yannick Chaval, Bruno Lourtet, Bruno Cargnelutti, Joel Merlet, Erwan Quéméré & Benoit Pujol
Accurate heritability estimates for fitness-related traits are required to predict an organism’s ability to respond to global change. Heritability estimates are theoretically expected to be inflated if, due to limited dispersal, individuals that share genes are also likely to share similar environments. However, if relatives occupy similar environments due, at least partly, to genetic variation for habitat selection, then accounting for environmental similarity in quantitative genetic models may result in diminished heritability estimates in wild...

Moths and butterflies on alien shores – global biogeography of non-native Lepidoptera

Richard Mally, Rebecca M. Turner, Rachael E. Blake, Gyda Fenn-Moltu, Cleo Bertelsmeier, Eckehard G. Brockerhoff, Robert J. B. Hoare, Helen F. Nahrung, Alain Roques, Deepa S. Pureswaran, Takehiko Yamanaka & Andrew M. Liebhold
Lepidoptera is a highly diverse, predominantly herbivorous insect order, with species transported to outside their native range largely facilitated by the global trade of plants and plant-based goods. Analogous to island disharmony, we examine invasion disharmony, where species filtering during invasions increases systematic compositional differences between native and non-native species assemblages, and test whether some families are more successful at establishing in non-native regions than others. We compared numbers of non-native, unintentionally introduced Lepidoptera species...

Data from: Variations in bark structural properties affect both water loss and carbon economics in neotropical savanna trees in the Cerrado region of Brazil

Paulo Eduardo Menezes-Silva, Lucas Loram-Lourenço, Fernanda Santos Farnese, Bruno Matheus Mendes Dario, Ana Claudia Martins, Marina Alves Aun, Priscila Ferreira Batista, Fabiano Guimarães Silva, Hervé Cochard & Augusto Cesar Franco
Even after complete stomatal closure, plants lose water through the leaf cuticles and bark. This residual water conductance of leaves (gleaf-res) and stems (gbark) can negatively impact plant water balance and affect plant survival in seasonally dry environments. However, little is known about the costs and benefits associated with such water leaks, especially on stem level. Here, we characterized the structural and functional determinants of the variability in gbark across tropical savanna species to elucidate...

Agroecosystem diversification with legumes or non-legumes improves differently soil fertility according to soil type

Marie Sauvadet, Jean Trap, Gaëlle Damour, Claude Plassard, Karel Van Den Meersche, Raphaël Achard, Clémentine Allinne, Patrice Autfray, Isabelle Bertrand, Eric Blanchart, Péninna Deberdt, Séguy Enock, Jean-Daniel Essobo, Grégoire Freschet, Mickaël Hedde, Elias De Melo Virginio Filho, Bodovololona Rabary, Miora Rakotoarivelo, Richard Randriamanantsoa, Béatrice Rhino, Aude Ripoche, Elisabeth Rosalie, Stéphane Saj, Thierry Becquer, Philippe Tixier … & Jean-Michel Harmand
Plant diversification through crop rotation or agroforestry is a promising way to improve sustainability of agroecosystems. Nonetheless, criteria to select the most suitable plant communities for agroecosystems diversification facing contrasting environmental constraints need to be refined. Here, we compared the impacts of 24 different plant communities on soil fertility across six tropical agroecosystems: either on highly weathered Ferralsols, with strong P limitation, or on partially weathered soils derived from volcanic material, with major N limitation....

When expansion stalls: an extension to the concept of range pinning in ecology

Thibaut Morel-Journel, Marjorie Haond, Laurent Lamy, David Muru, Lionel Roques, Ludovic Mailleret & Elodie Vercken
Identifying the factors modulating range expansion is essential to accurately predict changes in the spatial distribution of populations. By preventing population growth after dispersal, Allee effects can lead to front stops in discrete space, called ’pinning’ if permanent. However, other mechanisms, such as positive density-dependent dispersal, have also been shown to affect the rate of range expansion and generate discrete-space front stops, albeit temporarily. In this study, we investigated the stability of the front stops...

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.

Data from: Land-use legacies influence tree water-use efficiency and nitrogen dynamics in recently established European forests

Rossella Guerrieri, Marta Correia, Irene Martín-Forés, Raquel Alfaro-Sánchez, Joan Pino, Arndt Hampe, Fernando Valladares & Josep Espelta
1. Forest regrowth following farmland (agriculture and pasture) abandonment has been positively associated with a number of processes including the regulation of hydrological cycling, the enhancement of soil functioning, and an increase in forest productivity and carbon (C) sequestration. Although these changes in ecosystem functioning post-farmland abandonment have been observed in multiple locations and studies, the ecophysiological basis underpinning these patterns remains unclear. Here, we examine whether increased forest expansion following pastureland abandonment is associated...

A trait-based framework for predicting foodborne pathogen risk from wild birds

Olivia Smith, Elissa Olimpi, Nora Navarro-González, Kevin Cornell, Luke Frishkoff, Tobin Northfield, Timothy Bowles, Max Edworthy, Johnna Eilers, Zhen Fu, Karina Garcia, David Gonthier, Matthew Jones, Christina Kennedy, Christopher Latimer, Jeb Owen, Chika Sato, Joseph Taylor, Erin Wilson Rankin, William Snyder & Daniel Karp
Recent foodborne illness outbreaks have heightened pressures on growers to deter wildlife from farms, jeopardizing conservation efforts. However, it remains unclear which species, particularly birds, pose the greatest risk to food safety. Using >11,000 pathogen tests and 1,565 bird surveys covering 139 bird species from across the western U.S.A., we examined the importance of 11 traits in mediating wild bird risk to food safety. We tested whether traits associated with pathogen exposure (e.g., habitat associations,...

Data from: Fine-scale spatial genetic structure across the species range reflects recent colonization of high elevation habitats in silver fir (Abies alba Mill.)

Enikő I. Major, Mária Höhn, Camilla Avanzi, Bruno Fady, Katrin Heer, Lars Opgenoorth, Andrea Piotti, Flaviu Popescu, Dragos Postolache, Giovanni G. Vendramin & Katalin Csilléry
Variation in genetic diversity across species ranges has long been recognized as highly informative for assessing populations’ resilience and adaptive potential. The spatial distribution of genetic diversity within populations, referred to as fine-scale spatial genetic structure (FSGS), also carries information about recent demographic changes, yet it has rarely been connected to range scale processes. We studied eight silver fir (Abies alba Mill.) population pairs (sites), growing at high and low elevations, representative of the main...

Bryophyte microecosystem experiment

Adam Vanbergen, Claire Boissieres, Alan Gray & Daniel Chapman
Ecosystems face multiple, potentially interacting, anthropogenic pressures that can modify biodiversity and ecosystem functioning. Using a bryophyte-microarthropod microecosystem we tested the combined effects of habitat loss, episodic heat-shocks and an introduced non-native apex predator on ecosystem function (chlorophyll fluorescence as an indicator of photosystem II function) and microarthropod communities (abundance and body size). Photosynthetic function was degraded by the sequence of heat-shock episodes, but unaffected by microecosystem patch size or top-down pressure from the introduced...

Data for: Advanced infections by cucurbit yellow stunting disorder virus encourage whitefly vector colonization while discouraging non-vector aphid competitors

Kerry Mauck, Quentin Chesnais & Penglin Sun
Plant viruses can change hosts in ways that increase vector contacts, virion acquisition, and subsequent vector dispersal to susceptible hosts. Based on this, researchers have proposed that virus-induced phenotypes are the product of adaptations to “manipulate” hosts in ways that increase transmission. Theoretical models of virus spread in crops support this proposition; “manipulative” viruses spread faster and to a greater extent. However, both empirical and theoretical studies on manipulation are disproportionately focused on a few...

Detecting selection using extended haplotype homozygosity (EHH)-based statistics in unphased or unpolarized data

Alexander Klassmann & Mathieu Gautier
Analysis of population genetic data often includes the search for genomic regions with signs of recent positive selection. One of the approaches involves the concept of Extended Haplotype Homozygosity (EHH) and its associated statistics. These statistics typically need phased haplotypes and, some of them, polarized variants. Here, we unify and extend previously proposed modifications to loosen these requirements. We compare the modified versions with the original ones by measuring the False Discovery Rate in simulated...

Ladybird beetles' life history traits

Jean Louis RGM Hemptinne, Emilie Lecompte, Arnaud Sentis, Anthony F. G. Dixon & Alexandra Magro
1. The balance between risk and benefit of exploiting resources drives life history evolution in organisms. Predators are naturally recognized as major drivers of the life history evolution of their prey. Although prey may also influence the life history evolution of their predators in the context of an evolutionary arms race, there is far more evidence of the role of predators than of prey. 2. The goal of this study was to investigate the role...

Plant dispersal syndromes are unreliable as predictors of zoochory and long-distance dispersal by ungulates and waterbirds

Andy J. Green, Christophe Baltzinger & Ádám Lovas-Kiss
Plant dispersal syndromes are allocated based on diaspore morphology and used to predict mechanisms of dispersal. Many authors assume that only angiosperms with endozoochory, epizoochory or anemochory syndromes have a long-distance dispersal (LDD) mechanism. Too much faith is often placed in classical syndromes to explain historical dispersal events and to predict future ones. The “endozoochory syndrome” is actually a “frugivory syndrome” and has often diverted attention from endozoochory by non-frugivores (e.g. waterbirds and large herbivores)...

Landscape drivers of pests and pathogens abundance in arable crops

Corentin Barbu, Thomas Delaune, Malick S. Ouattara, Remy Ballot, Christophe Sausse, Irène Felix, Fabienne Maupas, Mathilde Chen, Muriel Morison & David Makowski
Farmers’ use of fungicides and insecticides constitutes a major threat to biodiversity that is also endangering agriculture itself. Landscapes could be designed to take advantage of the dependencies of pests, pathogens, and their natural enemies on elements of the landscape. Yet the complexity of the interactions makes it difficult to establish general rules. In our study, we sought to characterize the impact of the landscape on pest and pathogen prevalence, taking into account both crop...

Do human infrastructures shape nest distribution in the landscape depending on individual personality in a farmland bird of prey?

Juliette Rabdeau, Beatriz Arroyo, Francois Mougeot, Isabelle Badenhausser, Vincent Bretagnolle & Karine Monceau
1. Individuals´ distribution across habitats may depend on their personality. Human activities and infrastructures are critical elements of the landscape that may impact the habitat selection process. However, depending on their personality, individuals may respond differently to these unnatural elements. 2. In the present study, we first investigated whether some human infrastructures (buildings, roads and paths) shaped Montagu’s harrier nest spatial distribution in the landscape according to female personality (boldness). Second, we tested if the...

I alternate therefore I generalize: how the intrinsic resistance risk of fungicides counterbalances their durability

Agathe Ballu, Philomène Despréaux, Clémentine Duplaix, Anne Dérédec, Florence Carpentier & Anne-Sophie Walker
The evolution of resistance to pesticides is a major burden in agriculture. Resistance management involves maximizing selection pressure heterogeneity, particularly by combining active ingredients with different modes of action. We tested the hypothesis that alternation may delay the build-up of resistance not only by spreading selection pressure over longer periods, but also by decreasing the rate of evolution of resistance to alternated fungicides, by applying an experimental evolution approach to the economically important crop pathogen...

Landscape composition and life‐history traits influence bat movement and space use: Analysis of 30 years of published telemetry data

Alexis Laforge, Luc Barbaro & Frédéric Archaux
Using temperate bats, a group of particular conservation concern, we investigated how morphological traits, habitat specialization and environmental variables affect home range sizes and daily foraging movements, using a compilation of 30 years of published bat telemetry data in Northern America and Europe for the period 1988 – 2016. We compiled data on home range size and mean daily distance between roosts and foraging areas at both colony and individual levels from 166 studies of...

Data from: Landscape composition and life-history traits influence bat movement and space use: analysis of 30 years of published telemetry data

Alexis Laforge, Frederic Archaux, Aurélie Coulon, Clélia Sirami, Jérémy Froidevaux, Nicolas Gouix, Sylvie Ladet, Hilaire Martin, Kévin Barré, Fabien Claireau, Christian Kerbiriou, Charlotte Roemer & Luc Barbaro
Aim: Animal movement determines home range patterns, which in turn affect individual fitness, population dynamics and ecosystem functioning. Using temperate bats, a group of particular conservation concern, we investigated how morphological traits, habitat specialization and environmental variables affect home range sizes and daily foraging movements, using a compilation of 30 years of published bat telemetry data. Location: Northern America and Europe. Time period: 1988 – 2016. Major taxa studied: Bats. Methods: We compiled data on...

How to achieve a higher selection plateau in forest tree breeding? Fostering heterozygote x homozygote relationships in optimal contribution selection in the case study of Populus nigra

Mathieu Tiret, Marie Pégard & Leopoldo Sánchez
In breeding, Optimal Contribution Selection (OCS) is one of the most effective strategies to balance short- and long-term genetic responses, by maximizing genetic gain and minimizing global coancestry. Considering genetic diversity in the selection dynamic – through coancestry – is undoubtedly the reason for the success of OCS, as it avoids intial loss of favorable alleles. Originally formulated with the pedigree relationship matrix, global coancestry can nowadays be assessed with one of the possible formulations...

Adaptive population structure shifts in invasive parasitic mites, Varroa destructor

Arrigo Moro, Tjeerd Blacquière, Bjorn Dahle, Vincent Dietemann, Yves Le Conte, Locke Barbara, Peter Neumann & Alexis Beaurepaire
Comparative studies of genetic diversity and population structure can shed light on the ecological and evolutionary factors governing host–parasite interactions. Even though invasive parasites are considered of major biological importance, little is known about their adaptive potential when infesting the new hosts. Here, the genetic diversification of Varroa destructor, a novel parasite of Apis mellifera originating from Asia, was investigated using population genetics to determine how the genetic structure of the parasite changed in distinct...

Least‐cost path analysis for urban greenways planning: a test with moths and birds across two habitats and two cities

Manon Balbi, Solène Croci, Eric J. Petit, Alain Butet, Romain Georges, Luc Madec, Jean-Pierre Caudal & Aude Ernoult
1. One of the major planning tools to respond to urban landscape fragmentation is the development of ecological corridors, i.e. interconnected networks of urban green and blue spaces. Least-cost paths (LCP) appear to be an easy and appropriate resistance-based modeling method to respond to urban planners’ needs. However, the ecological validation of urban corridors using LCP is rarely performed and needs to be generalized to different species, habitats and cities. 2. We developed an experimental...
