Data from: Multiple facets of diversity effects on plant productivity: species richness, functional diversity, species identity and intraspecific competition

Lucie Mahaut, Florian Fort, Violle Cyrille & Grégoire T. Freschet
1. Deciphering the mechanisms that drive variation in biomass production across plant communities of contrasting species composition and diversity is a main challenge of biodiversity-ecosystem functioning research. Niche complementarity and selection effect have been widely investigated to address biodiversity-productivity relationships. However, the overlooking of the specific role played by key species have limited so far our capacity to comprehensively assess the relative importance of other potential drivers of biodiversity effects. 2. Here, we conducted a...

Data from: Leaf drought tolerance cannot be inferred from classic leaf traits in a tropical rainforest

Isabelle Maréchaux, Laurent Saint-André, Megan K. Bartlett, Lawren Sack & Jérôme Chave
Plants are enormously diverse in their traits and ecological adaptation, even within given ecosystems, such as tropical rainforests. Accounting for this diversity in vegetation models poses serious challenges. Global plant functional trait databases have highlighted general trait correlations across species that have considerably advanced this research program. However, it remains unclear whether trait correlations found globally hold within communities, and whether they extend to drought tolerance traits. For 134 individual plants spanning a range of...

Data from: Filling a gap in the proboscidean fossil record: a new genus from the Lutetian of Senegal

Rodolphe Tabuce
A long hiatus encompassing most of the Eocene (end of the Ypresian to the early Priabonian) breaks up the proboscidean evolutionary history, which is otherwise documented by a rich fossil record. Only two post Ypresian localities from West Africa (Mali and Senegal) yielded scarce Moeritherium-like dental remains. Here, we study one of these remains from Senegal and name a new genus, Saloumia. This taxon, confidently mid-Lutetian in age, evokes Moeritherium and elephantifoms in view of...

Data from: Diet variability among insular populations of Podarcis lizards reveals diverse strategies to face resource-limited environments

Maxime Taverne, Anne-Claire Fabre, Nina King-Gillies, Marija Krajnović, Duje Lisičić, Louise Martin, Leslie Michal, Donat Petricioli, Anamaria Stambuk, Zoran Tadić, Chloé Vigliotti, Beck Wehrle & Anthony Herrel
Access to resources is a dynamic and multi-causal process that determines the success and survival of a population. It is therefore often challenging to disentangle the factors affecting ecological traits like diet. Insular habitats provide a good opportunity to study how variation in diet originates, in particular in populations of mesopredators such as lizards. Indeed, high levels of population density associated with low food abundance and low predation are selection pressures typically observed on islands....

Data from: Habitat diversity associated with island size and environmental filtering control the species richness of rock-savanna plants in neotropical inselbergs

Ludovic Henneron, Corinne Sarthou, Jean-Christophe De Massary & Jean-François Ponge
Disentangling the multiple factors controlling species diversity is a major challenge in ecology. Island biogeography and environmental filtering are two influential theories emphasizing respectively island size and isolation, and the abiotic environment, as key drivers of species richness. However, few attempts have been made to quantify their relative importance and investigate their mechanistic basis. Here, we applied structural equation modelling, a powerful method allowing test of complex hypotheses involving multiple and indirect effects, on an...

Data from: Joint estimation of survival and breeding probability in female dolphins and calves with uncertainty in state assignment

Pauline Couet, François Gally, Coline Canonne & Aurélien Besnard
While the population growth rate in long-lived species is highly sensitive to adult survival, reproduction can also significantly drive population dynamics. Reproductive parameters can be challenging to estimate as breeders and non-breeders may vary in resighting probability and reproductive status may be difficult to assess. We extended capture–recapture (CR) models previously fitted for data on other long-lived marine mammals to estimate demographic parameters while accounting for detection heterogeneity between individuals and state uncertainty regarding reproductive...

Data from: Repeated evolution of asymmetric genitalia and right-sided mating behavior in the Drosophila nannoptera species group

Andrea E. Acurio, Flor T. Rhebergen, Sarah E. Paulus, Virginie Courtier-Orgogozo & Michael Lang
Background: Male genitals have repeatedly evolved left-right asymmetries, and the causes of such evolution remain unclear. The Drosophila nannoptera group contains four species, among which three exhibit left-right asymmetries of distinct genital organs. In the most studied species, Drosophila pachea, males display asymmetric genital lobes and they mate right-sided on top of the female. Copulation position of the other species is unknown. Results: To assess whether the evolution of genital asymmetry could be linked to...

Data from: Breakdown of gametophytic self-incompatibility in subdivided populations

Thomas Brom, Vincent Castric & Sylvain Billiard
In many hermaphroditic flowering plants self-fertilization is prevented by self-incompatibility (SI), often controlled by a single locus, the S-locus. In single isolated populations, the maintenance of SI depends chiefly on inbreeding depression and the number of SI alleles at the S-locus. In subdivided populations, however, population subdivision has complicated effects on both the number of SI alleles and the level of inbreeding depression, rendering the maintenance of SI difficult to predict. Here, we explore the...

Data from: From groups to communities in western lowland gorillas

Giovanni Forcina, Dominique Vallet, Pascaline J. Le Gouar, Rubén Bernardo-Madrid, Germán Illera, Guillem Molina-Vacas, Stéphane Dréano, Eloy Revilla, José Domingo Rodríguez-Tejeiro, Nelly Ménard, Magdalena Bermejo, Carles Vilà & José Domingo Rodríguez-Teijeiro
Social networks are the result of interactions between individuals at different temporal scales. Thus, sporadic intergroup encounters and individual forays play a central role in defining the dynamics of populations in social species. We assessed the rate of intergroup encounters for three western lowland gorilla (Gorilla gorilla gorilla) groups with daily observations over five years, and noninvasively genotyped a larger population over four months. Both approaches revealed a social system much more dynamic than anticipated,...

Data from: The interplay of landscape composition and configuration: new pathways to manage functional biodiversity and agro-ecosystem services across Europe

Emily A. Martin, Matteo Dainese, Yann Clough, András Báldi, Riccardo Bommarco, Vesna Gagic, Michael Garratt, Andrea Holzschuh, David Kleijn, Anikó Kovács-Hostyánszki, Lorenzo Marini, Simon G. Potts, Henrik G. Smith, Diab Al Hassan, Matthias Albrecht, Georg K. S. Andersson, Josep Asis, Stephanie Aviron, Mario Balzan, Laura Baños-Picón, Ignasi Bartomeus, Peter Batary, Françoise Burel, Berta Caballero-López, Elena D. Concepcion … & Ingolf Steffan-Dewenter
Managing agricultural landscapes to support biodiversity and ecosystem services is a key aim of a sustainable agriculture. However, how the spatial arrangement of crop fields and other habitats in landscapes impacts arthropods and their functions is poorly known. Synthesising data from 49 studies (1515 landscapes) across Europe, we examined effects of landscape composition (% habitats) and configuration (edge density) on arthropods in fields and their margins, pest control, pollination and yields. Configuration effects interacted with...

Data from: Integrating reproductive phenology in Ecological Niche Models changed the predicted future ranges of a marine invader

Rosa M. Chefaoui, Alexandra Serebryakova, Aschwin H. Engelen, Frédérique Viard & Ester A. Serrao
Aim: Phenology of a wide diversity of organisms has a dependency on climate, usually with reproductive periods beginning earlier in the year and lasting longer at lower latitudes. Temperature and day length are known environmental drivers of the reproductive timing of many species. Hence, reproductive phenology is sensitive to warming and is important to be considered for reliable predictions of species distributions. This is particularly relevant for rapidly spreading non-indigenous species (NIS). In this study,...

Data from: Intraspecific and interspecific trait variability in tadpole metacommunities from the Brazilian Atlantic rainforest

Mainara Xavier Jordani, Nicolas Mouquet, Lilian Casatii, Marcelo Menin, Denise De Cerqueira Rossa-Feres & Cécile H. Albert
1. A better understanding of species coexistence and community dynamics may benefit from more insights on trait variability at the individual and species levels. 2. Tadpole assemblages offer an excellent system to understand the relative influence of intra- and interspecific variability on community assembly, due to their high phenotypic plasticity, and the strong influence that environmental variables have on their spatial distribution and individual performance. 3. Here we quantified the intra- and interspecific components of...

Data from: Numerical cognition in honeybees enables addition and subtraction

Scarlett R. Howard, Aurore Avarguès-Weber, Jair E. Garcia, Andrew D. Greentree & Adrian G. Dyer
Many animals understand numbers at a basic level for use in essential tasks such as foraging, shoaling, and resource management. However, complex arithmetic operations, such as addition and subtraction, using symbols and/or labeling have only been demonstrated in a limited number of nonhuman vertebrates. We show that honeybees, with a miniature brain, can learn to use blue and yellow as symbolic representations for addition or subtraction. In a free-flying environment, individual bees used this information...

Data from: Nutrient starvation impairs the trophic plasticity of reef-building corals under ocean warming

Leïla Ezzat, Jean-François Maguer, Renaud Grover, Cécile Rottier, Pascale Tremblay, Christine Ferrier-Pagès & Jean‐François Maguer
1) Global warming of the world’s oceans is driving reef-building corals towards their upper thermal limit, inducing bleaching, nutrient starvation and mortality. In addition, corals are predicted to experience large fluctuations in seawater nutrient concentrations, following water column stratification or eutrophication problems, which can further alter their nutritional capacities and ultimately their resilience to global change. 2) We investigated the effect of thermal stress and dissolved inorganic nutrient (DINUT) availability on the auto- and heterotrophic...

Data from: Genetic population structure and demography of an apex predator, the tiger shark Galeocerdo cuvier

Agathe Pirog, Sebastien Jaquemet, Virginie Ravigné, Geremy Cliff, Eric Clua, Bonnie J. Holmes, Nigel E. Hussey, John E.G. Nevill, Andrew J. Temple, Per Berggren, Laurent Vigliola & Hélène Magalon
Population genetics have been increasingly applied to study large sharks over the last decade. Whilst large shark species are often difficult to study with direct methods, improved knowledge is needed for both population management and conservation, especially for species vulnerable to anthropogenic and climatic impacts. The tiger shark, Galeocerdo cuvier, is an apex predator known to play important direct and indirect roles in tropical and sub-tropical marine ecosystems. While the global and Indo-West Pacific population...

Data from: Unveiling tipping points in long-term ecological records from Sphagnum-dominated peatlands

Mariusz Lamentowicz, Mariusz Gałka, Katarzyna Marcisz, Michał Słowiński, Kajukało-Drygalska Kajukało, Milva Druguet Dayras & Vincent E.J. Jassey
Unveiling past tipping points is a prerequisite for a better understanding of how individual species and entire ecosystems will respond to future climate change. Such knowledge is key for the implementation of biodiversity conservation. We identify the relationships between peatland vegetation and hydrological conditions over the past 2000 years using macrofossils, testate amoebae-based quantitative hydrological reconstructions, and Sphagnum-moss functional traits from seven Polish peatland records. Using threshold indicator taxa analysis (TITAN), we discovered that plant...

Data from: Changing landscapes of Southeast Asia and rodent-borne diseases: decreased diversity but increased transmission risks

Serge Morand, Kim Blasdell, Frédéric Bordes, Philippe Buchy, Bernard Carcy, Kittipong Chaisiri, Yannick Chaval, Julien Claude, Jean-François Cosson, Marc Desquesnes, Sathaporn Jittapalapong, Tawisa Jiyipong, Anamika Karnchanabanthoen, Pumhom Pornpan, Jean-Marc Rolain & Annelise Tran
The reduction in biodiversity through land use changes due to urbanization and agricultural intensification, appears linked to major epidemiological changes in many human diseases. Increasing disease risks and the emergence of novel pathogens appear to result from increased contact between wildlife, domesticated animals and humans. We investigate how increasing human domination of the environment may favor generalist and synanthropic rodent species and affect the diversity and prevalence of rodent-borne pathogens in Southeast Asia, a hotspot...

Data from: Nonlinear phenotypic variation uncovers the emergence of heterosis in Arabidopsis thaliana

François Vasseur, Louise Fouqueau, Dominique De Vienne, Thibault Nidelet, Cyrille Violle & Detlef Weigel
Heterosis describes the phenotypic superiority of hybrids over their parents in traits related to agronomic performance and fitness. Understanding and predicting nonadditive inheritance such as heterosis is crucial for evolutionary biology as well as for plant and animal breeding. However, the physiological bases of heterosis remain debated. Moreover, empirical data in various species have shown that diverse genetic and molecular mechanisms are likely to explain heterosis, making it difficult to predict its emergence and amplitude...

Data from: Metapopulation vicariance, age of island taxa and dispersal: a case study using the pacific plant genus Planchonella (Sapotaceae)

Ulf Swenson, J. Christopher Havran, Jérôme Munzinger, Stephen Mcloughlin & Stephan Nylinder
Oceanic islands originate from volcanism or tectonic activity without connections to continental landmasses, are colonized by organisms, and eventually vanish due to erosion and subsidence. Colonization of oceanic islands occurs through long-distance dispersals or metapopulation vicariance, the latter resulting in lineages being older than the islands they inhabit. If metapopulation vicariance is valid, island ages cannot be reliably used to provide maximum age constraints for molecular dating. We explore the relationships between the ages of...

Data from: At sea vocal repertoire of a foraging seabird

Andréa Thiebault, Isabelle Charrier, Pierre Pistorius & Thierry Aubin
Seabirds spend most of their time at sea, yet our knowledge of their activities and behaviour is limited due to difficulties of in-situ data collection. In particular, we know virtually nothing about their acoustic communication when at sea. We benefited from the recent development of miniaturised audio-recording devices to deployacoustic recorders on breeding Cape gannets Morus capensis to study their vocal activity while foraging. Call sequences were recorded on 1718 occasions, from which acoustic variables...

Data from: The preference-performance relationship as a means of classifying parasitoids according to their specialization degree

Lucie S. Monticelli, Le Thu Ha Nguyen, Edwige Amiens-Desneux, Chen Luo, Anne-Violette Lavoir, Jean-Luc Gatti & Nicolas Desneux
Host range in parasitoids could be described by the preference-performance hypothesis (PPH) where preference is defined as host acceptance and performance is defined as the sum of all species on which parasitoid offspring can complete their life cycle. The PPH predicts that highly suitable hosts will be preferred by ovipositing females. However, generalist parasitoids may not conform to this hypothesis if they attack a large range of hosts of varying suitability. Under laboratory conditions, we...

Sexual isolation with and without ecological isolation in marine isopods Jaera albifrons and J. praehirsuta

Ambre Ribardière, Elsa Pabion, Jérôme Coudret, Claire Daguin-Thiébaut, Céline Houbin, Stéphane Loisel, Sébastien Henry & Thomas Broquet
Sexual barriers associated with mate choice are often found to be associated with some level of ecological isolation between species. The independence and relative strength of sexual isolation are thus difficult to assess. Here we take advantage of a pair of marine isopod species (Jaera albifronsand J. praehirsuta) that show sexual isolation and coexist in populations where they share the same microhabitat or not (i.e. without or with ecological isolation). We estimated the strength of...

Data set corresponding to the manuscript : "Species diversity and composition drive the aesthetic value of coral reef fish assemblages".

Data from: Failure to coordinate management in transboundary populations hinders the achievement of national management goals: the case of wolverines in Scandinavia

Vincenzo Gervasi
1. Large carnivores are expanding in Europe, and their return is associated with conflicts that often result in policies to regulate their population size through culling. Being wide-ranging species, their populations are often distributed across several jurisdictions, which may vary in the extent to which they use lethal control. This creates the conditions for the establishment of source-sink dynamics across borders, which may frustrate the ability of countries to reach their respective management objectives. 2....
