Data from: Spatial genetic structure in Beta vulgaris subsp. maritima and Beta macrocarpa reveals the effect of contrasting mating system, influence of marine currents and footprints of postglacial recolonisation routes

Marie Leys, Eric J. Petit, Yasmina El-Bahloul, Camille Liso, Sylvain Fournet & Jean-Francois Arnaud
Understanding the factors that contribute to population genetic divergence across a species' range is a long-standing goal in evolutionary biology and ecological genetics. We examined the relative importance of historical and ecological features in shaping the present-day spatial patterns of genetic structure in two related plant species, Beta vulgaris subsp. maritima and Beta macrocarpa. Using nuclear and mitochondrial markers, we surveyed 93 populations from Brittany (France) to Morocco – the southern limit of their species'...

Data from: How Ebola impacts social dynamics in gorillas: a multistate modelling approach.

Céline Genton, Amandine Pierre, Romane Cristescu, Florence Lévréro, Sylvain Gatti, Jean-Sébastien Pierre, Nelly Ménard & Pascaline Le Gouar
Emerging infectious diseases can induce rapid changes in population dynamics and threaten population persistence. In socially structured populations, the transfers of individuals between social units, e.g. from breeding groups to non-breeding groups, shape population dynamics. We suggest that diseases may affect these crucial transfers. We aimed to determine how disturbance by an emerging disease affects demographic rates of gorillas, especially transfer rates within populations and immigration rates into populations. We compared social dynamics and key...

Data from: Short- and long-term effects of litter size manipulation in a small wild-derived rodent

Mikko Lehto Hürlimann, Antoine Stier, Olivier Scholly, François Crisuolo, Pierre Bize, M. Lehto Hurlimann, F. Criscuolo, O. Scholly, A. Stier & P. Bize
Iteroparous organisms maximise their overall fitness by optimising their reproductive effort over multiple reproductive events. Hence, changes in reproductive effort are expected to have both short- and long-term consequences on parents and their offspring. In laboratory rodents, manipulation of reproductive efforts during lactation have however revealed little short-term reproductive adjustments, suggesting that female laboratory rodents might express maximal rather than optimal levels of reproductive investments as observed in semelparous organisms. Using a litter size manipulation...

Data from: Additive genetic variance and developmental plasticity in growth trajectories in a wild cooperative mammal

Elise Huchard, Anne Charmantier, Sinead English, Andrew Bateman, Johanna F. Nielsen, Tim Clutton-Brock, J. F. Nielsen, S. English, A. Charmantier, E. Huchard, A. Bateman & T. Clutton-Brock
Individual variation in growth is high in cooperative breeders and may reflect plastic divergence in developmental trajectories leading to breeding vs. helping phenotypes. However, the relative importance of additive genetic variance and developmental plasticity in shaping growth trajectories is largely unknown in cooperative vertebrates. This study exploits weekly sequences of body mass from birth to adulthood to investigate sources of variance in, and covariance between, early and later growth in wild meerkats (Suricata suricatta), a...

Data from: Short-term variations in gene flow related to cyclic density fluctuations in the common vole

Bertrand Gauffre, Karine Berthier, Pablo Inchausti, Yannick Chaval, Jean-François Cosson & Vincent Bretagnolle
In highly fluctuating populations with complex social systems genetic patterns are likely to vary in space and time due to demographic and behavioural processes. Cyclic rodents are extreme examples of demographically instable populations that often exhibit strong social organisation. In such populations, kin structure and spacing behaviour may vary with density fluctuations and impact both the composition and spatial structure of genetic diversity. In this study, we analysed the multiannual genetic structure of a cyclic...

Data from: Do mites evolving in alternating host plants adapt to host switch?

Sara Magalhães, Aurelie Cailleau, Elodie Blanchet & Isabelle Olivieri
A fluctuating environment may be perceived as a composition of different environments, or as an environment per se, in which it is the fluctuation itself that poses a selection pressure. If so, then organisms may adapt to this alternation. We tested this using experimental populations of spider mites that have been evolving for 45 generations in a homogeneous environment (pepper or tomato plants), or in a heterogeneous environment composed of an alternation of these two...

Data from: Bouldering: an alternative strategy to long-vertical climbing in root-climbing hortensias

Carolina Granados Mendoza, Sandrine Isnard, Tristan Charles-Dominique, Jan Van Den Bulcke, Nick P. Rowe, Joris Van Acker, Paul Goetghebeur & Marie-Stéphanie Samain
In the Neotropics, the genus Hydrangea of the popular ornamental hortensia family is represented by climbing species that strongly cling to their support surface by means of adhesive roots closely positioned along specialized anchoring stems. These root-climbing hortensia species belong to the nearly exclusive American Hydrangea section Cornidia and generally are long lianescent climbers that mostly flower and fructify high in the host tree canopy. The Mexican species Hydrangea seemannii, however, encompasses not only long...

Data from: Early life expenditure in sexual competition is associated with increased reproductive senescence in male red deer

Jean-François Lemaître, Jean-Michel Gaillard, Josephine M. Pemberton, Tim H. Clutton-Brock, Daniel H. Nussey, D. H. Nussey, T. H. Clutton-Brock, J.-F. Lemaitre & J.-M. Gaillard
The evolutionary theories of senescence predict that investment in reproduction in early life should come at the cost of reduced somatic maintenance, and thus earlier or more rapid senescence. There is now growing support for such trade-offs in wild vertebrates, but these exclusively come from females. Here, we test this prediction in male red deer (Cervus elaphus) using detailed longitudinal data collected over a 40-year field study. We show that males which had larger harems...

Data from: Blacktip reef sharks, Carcharhinus melanopterus, have high genetic structure and varying demographic histories in their Indo-Pacific range

Thomas M. Vignaud, Johann Mourier, Jeffrey A. Maynard, Raphael Leblois, Julia L. Y. Spaet, Eric Clua, Valentina Neglia, Serge Planes & Julia L.Y. Spaet
For free-swimming marine species like sharks, only population genetics and demographic history analyses can be used to assess population health/status as baseline population numbers are usually unknown. We investigated the population genetics of blacktip reef sharks, Carcharhinus melanopterus; one of the most abundant reef-associated sharks and the apex predator of many shallow water reefs of the Indian and Pacific Oceans. Our sampling includes 4 widely separated locations in the Indo-Pacific and 11 islands in French...

Data from: Use of RAD sequencing for delimiting species

Eric Pante, Jawad Abdelkrim, Amelia Viricel, Delphine Gey, Scott France, Marie-Catherine Boisselier & Sarah Samadi
RAD-tag sequencing is a promising method for conducting genome-wide evolutionary studies. However, to date, only a handful of studies empirically tested its applicability above the species level. In this communication, we use RAD tags to contribute to the delimitation of species within a diverse genus of deep-sea octocorals, Chrysogorgia, for which few classical genetic markers have proved informative. Previous studies have hypothesized that single mitochondrial haplotypes can be used to delimit Chrysogorgia species. On the...

Data from: Microbiome affects egg carotenoid investment, nestling development and adult oxidative costs of reproduction in Great tits

Staffan Jacob, Nathalie Parthuisot, Armelle Vallat, Felipe Ramon-Portugal, Fabrice Helfenstein & Philipp Heeb
1. Parasites influence allocation trade-offs between reproduction and self-maintenance and consequently shape host life-history traits. The host microbiome includes pathogenic and commensal micro-organisms that are remarkable in their diversity and ubiquity. However, experimental studies investigating whether the microbiome shapes host reproduction are still lacking. 2. In this study, we tested whether the microbiome affects three important components of bird reproduction, namely (i) the maternal transfer of anti-microbial compounds to the eggs, (ii) the development of...

Data from: Avian top predator and the landscape of fear: responses of mammalian mesopredators to risk imposed by the golden eagle

Mari S. Lyly, Alexandre Villers, Elina Koivisto, Pekka Helle, Tuomo Ollila & Erkki Korpimäki
Top predators may induce extensive cascading effects on lower trophic levels, for example, through intraguild predation (IGP). The impacts of both mammalian and avian top predators on species of the same class have been extensively studied, but the effects of the latter upon mammalian mesopredators are not yet as well known. We examined the impact of the predation risk imposed by a large avian predator, the golden eagle (Aquila chrysaetos, L.), on its potential mammalian...

Data from: Contrasting genetic diversity patterns in two sister kelp species co-distributed along the coast of Brittany, France

Marine Robuchon, Line Le Gall, Stéphane Mauger & Myriam Valero
We investigated patterns of genetic structure in two sister kelp species to explore how distribution width along the shore, zonation, latitudinal distribution and historical factors contribute to contrasting patterns of genetic diversity. We implemented a hierarchical sampling scheme to compare patterns of genetic diversity and structure in these two kelp species co-distributed along the coasts of Brittany (France) using a total of 12 microsatellites, 9 for Laminaria hyperborea and 11 for Laminaria digitata, of which...

Data from: Life-history trait database of European reptile species

Annegret Grimm, Ana María Prieto Ramírez, Sylvain Moulherat, Julie Reynaud & Klaus Henle
Life-history data are essential for providing answers to a wide range of questions in evolution, ecology, and conservation biology. While life history data for many species, especially plants, are available online, life history traits of European reptiles are available only widely scattered in different languages and primarily in printed media. For this reason, we generated a comprehensive trait database covering all European reptile species. Data were compiled by searching the peer-reviewed and non-peer-reviewed literature. The...

Data from: Reduced survival and reproductive success generates selection pressure for the dengue mosquito Aedes aegypti to evolve resistance against infection by the microsporidian parasite Vavraia culicis

Victoria E. Sy, Philip Agnew, Christine Sidobre & Yannis Michalakis
The success and sustainability of control measures aimed at reducing the transmission of mosquito-borne diseases will depend on how they influence the fitness of mosquitoes in targeted populations. We investigated the effects of the microsporidian parasite Vavraia culicis on the survival, blood-feeding behaviour and reproductive success of female Aedes aegypti mosquitoes, the main vector of dengue. Infection reduced survival to adulthood and increased adult female mosquito age-dependent mortality relative to uninfected individuals; this additional mortality...

Data from: Habitat-driven population structure of bottlenose dolphins, Tursiops truncatus, in the North-East Atlantic

Marie Louis, Amélia Viricel, Tamara Lucas, Hélène Peltier, Eric Alfonsi, Simon Berrow, Andrew Brownlow, Pablo Covelo, Willy Dabin, Rob Deaville, Renaud De Stephanis, François Gally, Pauline Gauffier, Rod Penrose, Monica A. Silva, Christophe Guinet & Benoît Simon-Bouhet
Despite no obvious barrier to gene flow, historical environmental processes and ecological specializations can lead to genetic differentiation in highly mobile animals. Ecotypes emerged in several large mammal species as a result of niche specializations and/or social organization. In the North-West Atlantic, two distinct bottlenose dolphin (Tursiops truncatus) ecotypes (i.e. ‘coastal’ and ‘pelagic’) have been identified. Here, we investigated the genetic population structure of North-East Atlantic (NEA) bottlenose dolphins on a large scale through the...

Data from: The dynamics of niche evolution upon abrupt environmental change

Romain Gallet, Yasmin Latour, Bradley Stephen Hughes, Thomas Lenormand & Bradley S. Hughes
Abrupt environmental changes are of particular interest to understand how species can quickly evolve at the boundary of their current niche. In particular the ‘sliding niche’ model, wherein a niche shifts globally toward the new condition, has been utilized in understanding and modeling this process. Here, we investigate the dynamics of relative fitness change in four evolutionary replicates of Escherichia coli populations exposed to an extreme pH shift. We analyzed these changes at generations 500,...

Data from: Paternal signature in kin recognition cues of a social insect: concealed in juveniles, revealed in adults

Janine W. Y. Wong, Joël Meunier, Christophe Lucas, Mathias Kölliker, M. Kolliker, J. W. Y. Wong & C. Lucas
Kin recognition is a key mechanism to direct social behaviours towards related individuals or avoid inbreeding depression. In insects, recognition is generally mediated by cuticular hydrocarbon (CHC) compounds, which are partly inherited from parents. However, in social insects, potential nepotistic conflicts between group members from different patrilines are predicted to select against the expression of patriline-specific signatures in CHC profiles. Whereas this key prediction in the evolution of insect signalling received empirical support in eusocial...

Data from: Multicollinearity in spatial genetics: separating the wheat from the chaff using commonality analyses

Jerome G. Prunier, Marc Colyn, Kim F. Nimon, Xavier Legendre & Marie Christine Flamand
Direct gradient analyses in spatial genetics provide unique opportunities to describe the inherent complexity of genetic variation in wildlife species and are the object of many methodological developments. However, multicollinearity among explanatory variables are a systemic issue in multivariate regression analyses and are likely to cause serious difficulties in properly interpreting results of direct gradient analyses, with the risk of erroneous conclusions, misdirected research and inefficient or counter-productive conservation measures. Using simulated datasets along with...

Data from: The population biology of fungal invasions

Pierre Gladieux, Alice Feurtey, Michael E. Hood, Alodie Snirc, Joanne Clavel, Cyril Dutech, Melanie Roy, Tatiana Giraud, C. Dutech, M. Roy, P. Gladieux, A. Feurtey, A. Snirc, T. Giraud & J. Clavel
Fungal invasions are increasingly recognized as a significant component of global changes, threatening ecosystem health and damaging food production. Invasive fungi also provide excellent models to evaluate the generality of results based on other eukaryotes. We first consider here the reasons why fungal invasions have long been overlooked: they tend to be inconspicuous, and inappropriate methods have been used for species recognition. We then review the information available on the patterns and mechanisms of fungal...

Data from: Bushmeat genetics: setting up a reference framework for the DNA-typing of African forest bushmeat

Philippe Gaubert, Flobert Njiokou, Ayodeji Olayemi, Paolo Pagani, Sylvain Dufour, Emmanuel Danquah, Mac Elikem K. Nutsuakor, Gabriel Ngua, Alain-Didier Missoup, Pablo A. Tedesco, Rémy Dernat & Agostinho Antunes
The bushmeat trade in tropical Africa represents illegal, unsustainable off-takes of millions of tons of wild game – mostly mammals – per year. We sequenced four mitochondrial gene fragments (cyt b, COI, 12S, 16S) in >300 bushmeat items representing nine mammalian orders and 59 morphological species from five western and central African countries (Guinea, Ghana, Nigeria, Cameroon and Equatorial Guinea). Our objectives were to assess the efficiency of cross-species PCR amplification and to evaluate the...

Data from: Uropygial gland size and composition varies according to experimentally modified microbiome in Great tits

Staffan Jacob, Anika Immer, Sarah Leclaire, Nathalie Parthuisot, Christine Ducamp, Gilles Espinasse & Philipp Heeb
Background: Parasites exert important selective pressures on host life history traits. In birds, feathers are inhabited by numerous microorganisms, some of them being able to degrade feathers or lead to infections. Preening feathers with secretions of the uropygial gland has been found to act as an antimicrobial defence mechanism, expected to regulate feather microbial communities and thus limit feather abrasion and infections. Here, we used an experimental approach to test whether Great tits (Parus major)...

Data from: Climatic conditions cause complex patterns of covariation between demographic traits in a long-lived raptor

Ivar Herfindal, Martijn Van De Pol, Jan T. Nielsen, Bernt-Erik Sæther, Anders P. Møller & Bernt-Erik Saether
1. Environmental variation can induce life-history changes that can last over a large part of the lifetime of an organism. If multiple demographic traits are affected, expected changes in climate may influence environmental covariances among traits in a complex manner. Thus, examining the consequences of environmental fluctuations requires that individual information at multiple life stages is available, which is particularly challenging in long-lived species. 2. Here, we analyse how variation in climatic conditions occurring in...

Data from: The consequences of co-infections for parasite transmission in the mosquito Aedes aegypti

Alison B. Duncan, Philip Agnew, Valérie Noel & Yannis Michalakis
1)Co-infections may modify parasite transmission opportunities directly as a consequence of interactions in the within host environment, but also indirectly through changes in host life-history. Furthermore, host and parasite traits are sensitive to the abiotic environment with variable consequences for parasite transmission in co-infections. (2)We investigate how co-infection of the mosquito Aedes aegypti with two microsporidian parasites (Vavraia culicis and Edhazardia aedis) at two levels of larval food availability affects parasite transmission directly, and indirectly...

Data from: Decomposing changes in phylogenetic and functional diversity over space and time

Loïc Chalmandrier, Tamara Münkemüller, Vincent Devictor, Sébastien Lavergne & Wilfried Thuiller
1. The α, β, γ diversity decomposition methodology is commonly used to investigate changes in diversity over space or time but rarely conjointly. However, with the ever-increasing availability of large-scale biodiversity monitoring data, there is a need for a sound methodology capable of simultaneously accounting for spatial and temporal changes in diversity. 2. Using the properties of Chao's index, we adapted Rao's framework of diversity decomposition between orthogonal dimensions to a multiplicative α, β, γ...
