Data from: High-throughput sequencing of transposable element insertions suggests adaptive evolution of the invasive Asian Tiger Mosquito towards temperate environments

Clément Goubert, Hélène Henri, Guillaume Minard, Claire Valiente Moro, Patrick Mavingui, Cristina Vieira & Matthieu Boulesteix
Invasive species represent unique opportunities to evaluate the role of local adaptation during colonization of new environments. Among these species, the Asian tiger mosquito, Aedes albopictus, is a threatening vector of several human viral diseases, including dengue and chikungunya, and raises concerns about the Zika fever. Its broad presence in both temperate and tropical environments has been considered the reflection of great “ecological plasticity.” However, no study has been conducted to assess the role of...

Yuanzhi Li, Bill Shipley, Jodi N. Price, Vinícius De L. Dantas, Riin Tamme, Mark Westoby, Andrew Siefert, Brandon S. Schamp, Marko J. Spasojevic, Vincent Jung, Daniel C. Laughlin, Sarah J. Richardson, Yoann Le Bagousse-Pinguet, Christian Schöb, Antonio Gazol, Honor C. Prentice, Nicolas Gross, Jacob Overton, Marcus V. Cianciaruso, Frédérique Louault, Chiho Kamiyama, Tohru Nakashizuka, Kouki Hikosaka, Takehiro Sasaki, Masatoshi Katabuchi … & Marco A. Batalha
How the patterns of niche occupancy vary from species-poor to species-rich communities is a fundamental question in ecology that has a central bearing on the processes that drive patterns of biodiversity. As species richness increases, habitat filtering should constrain the expansion of total niche volume, while limiting similarity should restrict the degree of niche overlap between species. Here, by explicitly incorporating intraspecific trait variability, we investigate the relationship between functional niche occupancy and species richness...

Data from: Winter warming effects on tundra shrub performance are species-specific and dependent on spring conditions

Eveline J. Krab, Jonas Rönnefarth, Marina Becher, Gesche Blume-Werry, Frida Keuper, Jonatan Klaminder, Juergen Kreyling, Kobayashi Makoto, Ann Milbau, Ellen Dorrepaal & Jonas Roennefarth
1. Climate change driven increases in winter temperatures positively affect conditions for shrub growth in arctic tundra by decreasing plant frost damage and stimulation of nutrient availability. However, the extent to which shrubs may benefit from these conditions may be strongly dependent on the following spring climate. Species-specific differences in phenology and spring frost sensitivity likely affect shrub growth responses to warming. Additionally, effects of changes in winter and spring climate may differ over small...

Data from: Using sensitivity analysis to identify key factors for the propagation of a plant epidemic

Loup Rimbaud, Claude Bruchou, Sylvie Dallot, David R.J. Pleydell, Emmanuel Jacquot, Samuel Soubeyrand, Gaël Thébaud & David R. J. Pleydell
Identifying the key factors underlying the spread of a disease is an essential but challenging prerequisite to design management strategies. To tackle this issue, we propose an approach based on sensitivity analyses of a spatiotemporal stochastic model simulating the spread of a plant epidemic. This work is motivated by the spread of sharka, caused by Plum pox virus, in a real landscape. We first carried out a broad-range sensitivity analysis, ignoring any prior information on...

Data from: Plant interactions as biotic drivers of plasticity in leaf litter traits and decomposability of Quercus petraea

Ludovic Henneron, Matthieu Chauvat, Frédéric Archaux, Marthe Akpa-Vinceslas, Fabrice Bureau, Yann Dumas, Laurent Mignot, François Ningre, Sandrine Perret, Claudine Richter, Philippe Balandier & Michael Aubert
The importance of plant litter traits and decomposability for nutrient cycling processes and plant community dynamics through plant-litter-soil feedbacks has been largely emphasized. However, the role of biotic interactions as drivers of intraspecific variability in litter traits remains surprisingly little studied. In this study, we used a large-scale, multi-site network of long-term tree removal experiments manipulating the abundance of a foundation tree species, i.e. Quercus petraea, to assess how plant interactions control intraspecific variation in...

Data from: Pulsed food resources, but not forest cover, determines lifetime reproductive success in a forest-dwelling rodent

Katrine S. Hoset, Alexandre Villers, Ralf Wistbacka & Vesa Selonen
1. The relative contributions of habitat and food availability on fitness may provide evidence for key habitat features needed to safeguard population persistence. However, defining habitat quality for a species can be a complex task, especially if knowledge on the relationship between individual performance and habitat quality is lacking. 2. Here, we determined the relative importance of availability of suitable forest habitat, body mass, and food from masting tree species on female lifetime reproductive success...

Data from: The effects of climate change on a mega-diverse country: predicted shifts in mammalian species richness and turnover in continental Ecuador.

Paula Iturralde-Pólit, Olivier Dangles, Santiago F. Burneo & Christine N. Meynard
Ecuador is one of 17 nations with the greatest diversity in the world, sheltering lowland and mountain regions that are considered global biodiversity hotspots. While these regions are projected to be highly impacted by climate change, it is not clear what would be the consequences for faunal diversity and conservation. To address this issue, we used an ensemble of 8 species distribution models (SDM) to determine future shifts and identify areas of high changes in...

Data from: Stocking activities for the Arctic charr in Lake Geneva: genetic effects in space and time

Romain Savary, Christophe Dufresnes, Alexis Champigneulle, Arnaud Caudron, Sylvain Dubey, Nicolas Perrin & Luca Fumagalli
Artificial stocking practices are widely used by resource managers worldwide, in order to sustain fish populations exploited by both recreational and commercial activities, but their benefits are controversial. Former practices involved exotic strains, although current programs rather consider artificial breeding of local fishes (supportive breeding). Understanding the complex genetic effects of these management strategies is an important challenge with economic and conservation implications, especially in the context of population declines. In the present study, we...

Data from: Species richness effects on grassland recovery from drought depend on community productivity in a multisite experiment

Juergen Kreyling, Jürgen Dengler, Julia Walter, Nikolay Velev, Emin Ugurlu, Desislava Sopotlieva, Johannes Ransijn, Catherine Picon-Cochard, Ivan Nijs, Pauline Hernandez, Behlül Güler, Philipp Von Gillhaussen, Hans J. De Boeck, Juliette M. G. Bloor, Sigi Berwaers, Carl Beierkuhnlein, Mohammed A. S. Arfin Khan, Iva Apostolova, Yasin Altan, Michaela Zeiter, Camilla Wellstein, Marcelo Sternberg, Andreas Stampfli, Giandiego Campetella, Sándor Bartha … & Juliette M.G. Bloor
Biodiversity can buffer ecosystem functioning against extreme climatic events, but few experiments have explicitly tested this. Here, we present the first multisite biodiversity × drought manipulation experiment to examine drought resistance and recovery at five temperate and Mediterranean grassland sites. Aboveground biomass production declined by 30% due to experimental drought (standardised local extremity by rainfall exclusion for 72–98 consecutive days). Species richness did not affect resistance but promoted recovery. Recovery was only positively affected by...

Data from: Modelling the probability of microhabitat formation on trees using cross-sectional data

Laurent Larrieu & Alain Cabanettes
1. Context: Tree-related microhabitats (TreMs), such as trunk cavities, peeled bark, cracks or sporophores of lignicolous fungi, are essential to support forest biodiversity because they are used as substrate, foraging, roosting or breeding places by bryophytes, fungi, invertebrates and vertebrates. Biodiversity conservation requires the continuous presence of TreMs in a forest. However, little is known about their dynamics. Moreover, we usually have only cross-sectional TreM data (observations of many trees at a single time), making...

Data from: Selection on the morphology-physiology-performance nexus: lessons from freshwater stickleback morphs

Sergey Morozov, Tuomas Leinonen, Juha Merilä, R.J. Scott McCairns & R. J. Scott McCairns
Conspecifics inhabiting divergent environments frequently differ in morphology, physiology and performance, but the interrelationships amongst traits and with Darwinian fitness remains poorly understood. We investigated population differentiation in morphology, metabolic rate and swimming performance in three-spined sticklebacks (Gasterosteus aculeatus L.), contrasting a marine/ancestral population with two distinct freshwater morphotypes derived from it: the ‘typical’ low-plated morph, and a unique ‘small-plated’ morph. We test the hypothesis that similar to plate loss in other freshwater populations, reduction...

Data from: Patterns and drivers of biodiversity-stability relationships under climate extremes

Hans J. De Boeck, Juliette M. G. Bloor, Juergen Kreyling, Johannes C. G. Ransijn, Ivan Nijs, Anke Jentsch & Michaela Zeiter
Interactions between biodiversity loss and climate change present significant challenges for research, policy and management of ecosystems. Evidence suggests that high species diversity tends to increase plant community stability under interannual climate fluctuations and mild dry and wet events, but the overall pattern of diversity–stability relationships under climate extremes is unclear. We comprehensively review results from observational and experimental studies to assess the importance of diversity effects for ecosystem function under climate extremes. Both the...

Data from: Phenotypic selection and covariation in the life‐history traits of elephant seals: heavier offspring gain a double selective advantage

W. Chris Oosthuizen, Res Altwegg, Marie Nevoux, Marthán N. Bester, P.J. Nico De Bruyn & P. J. Nico De Bruyn
Early developmental conditions contribute to individual heterogeneity of both phenotypic traits and fitness components, ultimately affecting population dynamics. Although the demographic consequences of ontogenic growth are best quantified using an integrated measure of fitness, most analyses to date have instead studied individual fitness components in isolation. Here, wWe estimated phenotypic selection on weaning mass in female southern elephant seals (Mirounga leonina) by analyzing individual-based data collected between 1986 and 2016 with capture-recapture and matrix projection...

Data from: How to quantify a distance-dependent landscape effect on a biological response

Paul Miguet, Lenore Fahrig & Claire Lavigne
To quantify the effect of the surrounding landscape context on a biological response at a site, most studies measure landscape variables within discs centred on this biological response (threshold-based method). This implicitly assumes that the effect of a unit area of the landscape is consistent up to a threshold distance beyond which it drops to zero. However, it seems more likely that the landscape effect declines with increasing distance from the biological response point. Here...

Data from: Fungal adaptation to contemporary fungicide applications: the case of Botrytis cinerea populations from Champagne vineyards (France)

Anne-Sophie Walker, Virginie Ravigné, Adrien Rieux, S. Ali, F. Carpentier, Elisabeth Fournier, V. Ravigne & A.-S. Walker
In addition to being one of the most acute problems impeding chemical control of fungal diseases, the evolution of fungicide resistance is an emblematic case of local adaptation to spatially heterogeneous and temporally variable selection pressures. Here we dissected the adaptation of Botrytis cinerea (the causal agent of grey mould) populations on grapes to several fungicides. We carried out a 2-year survey (four collection dates) on three treated/untreated pairs of plots from vineyards in Champagne...

Data from: Neighborhood effects determine plant-herbivore interactions below ground

Wei Huang, Elias Zwimpfer, Maxime R. Hervé, Zoe Bont & Matthias Erb
1. Plant neighbors can strongly influence the interactions between herbivores and focal plants, for instance by providing food of different quality (consumptive effects) or by changing the behavior and metabolism of the herbivore and the focal plant without being consumed (non-consumptive effects). Determining the species-specific contributions of consumptive and non-consumptive effects is important to understand the ecophysiological mechanisms which underlie neighborhood effects. 2. We quantified the impact of nine different grassland plant species on the...

Data from: Biological traits, rather than environment, shape detection curves of large vertebrates in neotropical rainforests

Thomas Denis, Cécile Richard-Hansen, Olivier Brunaux, Marie-Pierre Etienne, Stéphane Guitet & Bruno Hérault
Line transect surveys are widely used in neotropical rainforests to estimate the population abundance of medium- and large-sized vertebrates. The use of indices such as Encounter Rate has been criticized because the probability of animal detection may fluctuate due to the heterogeneity of environmental conditions among sites. In addition, the morphological and behavioral characteristics (biological traits) of species affect their detectability. In this study, we compared the extent to which environmental conditions and species’ biological...

Data from: A novel locus on chromosome 1 underlies the evolution of a melanic plumage polymorphism in a wild songbird

Yann X.C. Bourgeois, Boris Delahaie, Mathieu Gautier, Emeline Lhuillier, Pierre-Jean G. Malé, Joris A.M. Bertrand, Josselin Cornuault, Kazumasa Wakamatsu, Olivier Bouchez, Claire Mould, Jade Bruxaux, Hélène Holota, Borja Mila, Christophe Thébaud, Joris A. M. Bertrand & Yann X. C. Bourgeois
Understanding the mechanisms responsible for phenotypic diversification within and among species ultimately rests with linking naturally occurring mutations to functionally and ecologically significant traits. Colour polymorphisms are of great interest in this context because discrete colour patterns within a population are often controlled by just a few genes in a common environment. We investigated how and why phenotypic diversity arose and persists in the Zosterops borbonicus white-eye of Reunion (Mascarene archipelago), a colour polymorphic songbird...

Data from: Finding the best management policy to eradicate invasive species from spatial ecological networks with simultaneous actions

Sam Nicol, Régis Sabbadin, Nathalie Peyrard & Iadine Chades
1. Spatial management of invasive species is more likely to be successful when multiple locations are treated simultaneously. However, selecting the best locations to act is difficult due to the many options available at any time. 2. We design a near-optimal policy for applying multiple actions simultaneously for faster invasive species control within a network. Our method uses a recent optimisation tool, the Graph-based Markov decision process (GMDP). Since the policy can be difficult to...

Data from: The power of evolutionary rescue is constrained by genetic load

Gavin S. Stewart, Madeline R. Morris, Allison B. Genis, Marianna Szűcs, Brett A. Melbourne, Simon J. Tavener & Ruth A. Hufbauer
Extinction risk of small isolated populations in changing environments can be reduced by rapid adaptation and subsequent growth to larger, less vulnerable sizes. Whether this process, called evolutionary rescue, is able to reduce extinction risk and sustain population growth over multiple generations is largely unknown. To understand the consequences of adaptive evolution as well as maladaptive processes in small isolated populations, we subjected experimental Tribolium castaneum populations founded with 10 or 40 individuals to novel...

Data from: Improving spatial predictions of taxonomic, functional and phylogenetic diversity

Manuela D'Amen, Ruben G. Mateo, Julien Pottier, Wilfried Thuiller, Luigi Maiorano, Loïc Pellissier, Charlotte Ndiribe, Nicolas Salamin & Antoine Guisan
1. In this study, we compare two community modelling approaches to determine their ability to predict the taxonomic, functional and phylogenetic properties of plant assemblages along a broad elevation gradient and at a fine resolution. The first method is the standard stacking individual species distribution modelling (SSDM) approach, which applies a simple environmental filter to predict species assemblages. The second method couples the SSDM and macroecological modelling (MEM - SSDM-MEM) approaches to impose a limit...

Data from: How do functional traits syndromes covary with growth and reproductive performance in a water-stressed population of Fagus sylvatica?

Aurore Bontemps, Hendrik Davi, François Lefèvre, Philippe Rozenberg & Sylvie Oddou-Muratorio
A central issue in plant evolutionary ecology is to understand how several coordinated suites of traits (i.e. traits syndrome) may be jointly selected within a single species. This study aims to describe patterns of variation and co-variation of functional traits in a water-stressed tree population and test their relationships with performance traits. Within a Mediterranean population of Fagus sylvatica experiencing recurrent summer droughts, we investigated the phenotypic variation of leaf unfolding phenology, Leaf Area (LA),...

Data from: Modelling unbiased dispersal kernels over continuous space by accounting for spatial heterogeneity in marking and observation efforts

Joël Chadoeuf, Alexandre Millon, Jean-Luc Bourrioux, Thierry Printemps, Benoit Van Hecke, Vincent Lecoustre & Vincent Bretagnolle
1. Although a key demographic trait determining the spatial dynamics of wild populations, dispersal is notoriously difficult to estimate in the field. Indeed, dispersal distances obtained from the monitoring of marked individuals typically lead to biased estimations of dispersal kernels as a consequence of i) restricted spatial scale of the study areas compared to species potential dispersal and ii) heterogeneity in marking and observation efforts and therfore in detection probability across space. 2. Here we...

Data from: The roots of the drought: hydrology and water uptake strategies mediate forest-wide demographic response to precipitation

Rutuja Chitra-Tarak, Laurent Ruiz, H. S. Dattaraja, M. S. Mohan Kumar, Jean Riotte, H. S. Suresh, Sean M. McMahon & Raman Sukumar
Drought-induced tree mortality is expected to increase globally due to climate change, with profound implications for forest composition, function and global climate feedbacks. How drought is experienced by different species is thought to depend fundamentally on where they access water vertically below ground, but this remains untracked so far due to the difficulty of measuring water availability at depths at which plants access water (few to several tens of meters), the broad temporal scales at...

Data from: Evolutionary dynamics of the leaf phenological cycle in an oak metapopulation along an elevation gradient

Cyril Firmat, Sylvain Delzon, Jean-Marc Louvet, Julien Parmentier, Antoine Kremer & J.-M. Louvet
It has been predicted that environmental changes will radically alter the selective pressures on phenological traits. Long-lived species, such as trees, will be particularly affected, as they may need to undergo major adaptive change over only one or a few generations. The traits describing the annual life cycle of trees are generally highly evolvable, but nothing is known about the strength of their genetic correlations. Tight correlations can impose strong evolutionary constraints, potentially hampering the...
