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: 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
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: 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: 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: 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
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: 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: 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: 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, 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: Genetic structure and hybridization in the species group of Ficus auriculata: can closely related sympatric Ficus species retain their genetic identity while sharing pollinators?

Zuo-Dong Wei, Noppol Kobmoo, Astrid Cruaud, Finn Kjellberg & Z.-D. Wei
Obligate mutualistic nursery pollination systems between insects and plants have led to substantial co-diversification involving at least some parallel cladogenesis, as documented in Yucca, Ficus and Phyllanthaceae. In such systems pollinators are generally species specific thus limiting hybridization and introgression among interfertile host species. Nevertheless, in the three systems, cases of one insect pollinating several plant species are reported. In most cases host plants sharing pollinators are allopatric. However in the case of the species...

Data from: Movement propensity and ability correlate with ecological specialisation in European land snails: comparative analysis of a dispersal syndrome

Maxime Dahirel, Eric Olivier, Annie Guiller, Marie-Claire Martin, Luc Madec & Armelle Ansart
Intra- and inter-specific differences in movement behaviour play an important role in the ecology and evolution of animals, particularly in fragmented landscapes. As a consequence of rarer and generally more fragmented habitat, and because dispersal tends to disrupt benefits brought by local adaptation, theory predicts that mobility and dispersal should be counter-selected in specialists. Using experimental data and phylogenetic comparative tools, we analysed movement propensity and capacity, as well as dispersal-related phenotypic traits, in controlled...

Data from: Genomics of the divergence continuum in an African plant biodiversity hotspot, I: drivers of population divergence in Restio capensis (Restionaceae)

Christian Lexer, Rafael O. Wüest, Sofia Mangili, Myriam Heuertz, Kai N. Stolting, Peter B. Pearman, Felix Forest, Nicolas Salamin, Niklaus E. Zimmermann & Eligio Bossolini
Understanding the drivers of population divergence, speciation and species persistence is of great interest to molecular ecology, especially for species-rich radiations inhabiting the world’s biodiversity hotspots. The toolbox of population genomics holds great promise for addressing these key issues, especially if genomic data are analyzed within a spatially and ecologically explicit context. We have studied the earliest stages of the divergence continuum in the Restionaceae, a species-rich and ecologically important plant family of the Cape...

Data from: Maternal exposure to predator scents: offspring phenotypic adjustment and dispersal

Elvire Bestion, Aimeric Teyssier, Fabien Aubret, Jean Clobert & Julien Cote
Predation is a strong selective pressure generating morphological, physiological and behavioural responses in organisms. As predation risk is often higher during juvenile stages, antipredator defences expressed early in life are paramount to survival. Maternal effects are an efficient pathway to produce such defences. We investigated whether maternal exposure to predator cues during gestation affected juvenile morphology, behaviour and dispersal in common lizards (Zootoca vivipara). We exposed 21 gravid females to saurophagous snake cues for one...

Data from: Computational design of protein-based inhibitors of Plasmodium vivax subtilisin-like 1 protease

Giacomo Bastianelli, Anthony Bouillon, Christophe Nguyen, Dung Le-Nguyen, Michael Nilges & Jean-Christophe Barale
Background: Malaria remains a major global health concern. The development of novel therapeutic strategies is critical to overcome the selection of multiresistant parasites. The subtilisin-like protease (SUB1) involved in the egress of daughter Plasmodium parasites from infected erythrocytes and in their subsequent invasion into fresh erythrocytes has emerged as an interesting new drug target. Findings: Using a computational approach based on homology modeling, protein–protein docking and mutation scoring, we designed protein–based inhibitors of Plasmodium vivax...

Data from: Fire evolution in the radioactive forests of Ukraine and Belarus: future risks for the population and the environment

Nikolaos Evangeliou, Yves Balkanski, Anne Cozic, Wei Min Hao, Florent Mouillot, Kirsten Thonicke, Ronan Paugam, Sergey Zibtsev, Timothy A. Mousseau, Rong Wang, Benjamin Poulter, Alex Petkov, Chao Yue, Patricia Cadule, Brigitte Koffi, Johannes W. Kaiser & Anders Pape Møller
This paper analyzes the current and future status of forests in Ukraine and Belarus that were contaminated after the nuclear disaster in 1986. Using several models, together with remote sensing data and observations, we studied how climate change in these forests may affect fire regimes. We investigated the possibility of 137Cs displacement over Europe by studying previous fire events, and examined three fire scenarios that depended on different emission altitudes of 137Cs, assuming that 10%...

Data from: Phylum-wide comparative genomics unravel the diversity of secondary metabolism in Cyanobacteria

Alexandra Calteau, David P. Fewer, Amel Latifi, Thérèse Coursin, Thierry Laurent, Jouni Jokela, Cheryl A. Kerfeld, Kaarina Sivonen, Jörn Piel & Muriel Gugger
Background: Cyanobacteria are an ancient lineage of photosynthetic bacteria from which hundreds of natural products have been described, including many notorious toxins but also potent natural products of interest to the pharmaceutical and biotechnological industries. Many of these compounds are the products of non-ribosomal peptide synthetase (NRPS) or polyketide synthase (PKS) pathways. However, current understanding of the diversification of these pathways is largely based on the chemical structure of the bioactive compounds, while the evolutionary...

Data from: DNA metabarcoding diet analysis for species with parapatric versus sympatric distribution: a case study on subterranean rodents

Carla M. Lopes, Marta De Barba, Frédéric Boyer, Céline Mercier, Pedro J. S. Da Silva Filho, Laura M. Heidtmann, Daniel Galiano, Bruno B. Kubiak, Patrícia Langone, Felipe M. Garcias, Ludovic Gielly, Eric Coissac, Thales R. O. De Freitas & Pierre Taberlet
Closely related sympatric species commonly develop different ecological strategies to avoid competition. Ctenomys minutus and C. flamarioni are subterranean rodents parapatrically distributed in the southern Brazilian coastal plain, showing a narrow sympatric zone. To gain understanding on food preferences and possible competition for food resources, we evaluated their diet composition performing DNA metabarcoding analyzes of 67 C. minutus and 100 C. flamarioni scat samples, collected along the species geographical ranges. Thirteen plant families, mainly represented...

Data from: Ecology of information: social transmission dynamics within groups of non-social insects

Marine Battesti, Cristian Pasquaretta, Celine Moreno, Serafino Teseo, Dominique Joly, Elizabeth Klensch, Odile Petit, Cedric Sueur & Frederic Mery
While many studies focus on how animals use public information, the dynamics of information spread and maintenance within groups, i.e. the ‘ecology of information’, have received little attention. Here we use fruitflies trained to lay eggs on specific substrates to implement information into groups containing both trained and untrained individuals. We quantify inter-individual interactions and then measure the spread of oviposition preference with behavioural tests. Untrained individuals increase their interactive approaches in the presence of...

Data from: The efficiency of close inbreeding to reduce genetic adaptation to captivity

Konstantinos Theodorou & Denis Couvet
Although ex situ conservation is indispensable for thousands of species, captive breeding is associated with negative genetic changes: loss of genetic variance and genetic adaptation to captivity that is deleterious in the wild. We used quantitative genetic individual-based simulations to model the effect of genetic management on the evolution of a quantitative trait and the associated fitness of wild-born individuals that are brought to captivity. We also examined the feasibility of the breeding strategies under...

Data from: Tracing the colonization and diversification of the worldwide seabird ectoparasite Ixodes uriae

Muriel Dietrich, Florent Kempf, Thierry Boulinier & Karen D. McCoy
Historical patterns of dispersal and population isolation are key components shaping contemporary genetic diversity across landscapes and require explicit consideration when examining the relative role of different factors in driving the evolution of host specificity in parasitic organisms. In this study, we investigate the worldwide colonisation history of a common ectoparasite of seabirds, the tick Ixodes uriae. This tick has a circumpolar distribution across both hemispheres, but has repeatedly formed host-specific races within different regions....

Data from: Origin, acquisition and diversification of heritable bacterial endosymbionts in louse flies and bat flies

Olivier Duron, Boris Droz, Arnaud Berthomieu & Steven M. Goodman
The γ-proteobacterium Arsenophonus and its close relatives (Arsenophonus and like organisms, ALOs) are emerging as a novel clade of endosymbionts, which are exceptionally widespread in insects. The biology of ALOs is, however, in most cases entirely unknown, and it is unclear how these endosymbionts spread across insect populations. Here, we investigate this aspect through the examination of the presence, the diversity and the evolutionary history of ALOs in 25 related species of blood-feeding flies: tsetse...

Data from: Comparative genomics of the mimicry switch in Papilio dardanus

Martijn J. T. N. Timmermans, Simon W. Baxter, Rebecca Clark, David G. Heckel, Heiko Vogel, Steve Collins, Alexie Papanicolaou, Iva Fukova, Mathieu Joron, Martin J. Thompson, Chris D. Jiggins, Richard H. Ffrench-Constant & Alfried P. Vogler
The African Mocker Swallowtail, Papilio dardanus, is a textbook example in evolutionary genetics. Classical breeding experiments have shown that wing pattern variation in this polymorphic Batesian mimic is determined by the polyallelic H locus that controls a set of distinct mimetic phenotypes. Using bacterial artificial chromosome (BAC) sequencing, recombination analyses and comparative genomics, we show that H co-segregates with an interval of less than 500 kb that is collinear with two other Lepidoptera genomes and...
