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

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: Climate change and human colonization triggered habitat loss and fragmentation in Madagascar.

Jordi Salmona, Rasmus Heller, Erwan Quéméré & Lounès Chikhi
The relative effect of past climate fluctuations and anthropogenic activities on current biome distribution is subject to increasing attention, notably in biodiversity hot spots. In Madagascar, where humans arrived in the last ~4 to 5,000 years, the exact causes of the demise of large vertebrates that cohabited with humans are yet unclear. The prevailing narrative holds that Madagascar was covered with forest before human arrival and that the expansion of grasslands was the result of...

Data from: An a posteriori species clustering for quantifying the effects of species interactions on ecosystem functioning

Benoît Jaillard, Camille Richon, Philippe Deleporte, Michel Loreau & Cyrille Violle
1. Quantifying the effects of species interactions is key to understanding the relationships between biodiversity and ecosystem functioning but remains elusive due to combinatorics issues. Functional groups have been commonly used to capture the diversity of forms and functions and thus simplify the reality. However, the explicit incorporation of species interactions is still lacking in functional group-based approaches. Here we propose a new approach based on an a posteriori clustering of species to quantify the...

Data from: The functional syndrome: linking individual trait variability to ecosystem functioning

Allan Raffard, Antoine Lecerf, Julien Cote, Mathieu Buoro, Remy Lassus & Julien Cucherousset
Phenotypic variability is increasingly assessed through functional response and effect traits, which provide a mechanistic framework for investigating how an organism responds to varying ecological factors and how these responses affect ecosystem functioning. Covariation between response and effect traits has been poorly examined at the intraspecific level, thus hampering progress in understanding how phenotypic variability alters the role of organisms in ecosystems. Using a multi-trait approach and a nine-month longitudinal monitoring of individual red-swamp crayfish...

Data from: Measuring selection when parents and offspring interact

Caroline E. Thomson & Jarrod D. Hadfield
Non-social and social selection gradients are key evolutionary parameters in systems where individuals interact. They are most easily obtained by regressing an individual's fitness on the trait values of the individual and its social partner. In the context of parental care it is more common to regress the trait value of the parents (i.e. the social partner) on a ‘mixed’ fitness measure that is a function of the parent's and offspring's fitness (for example, the...

Data from: Cooperative defence operates by social modulation of biogenic amine levels in the honeybee brain

Morgane Nouvian, Souvik Mandal, Charlène Jamme, Charles Claudianos, Patrizia D'Ettorre, Judith Reinhard, Andrew B. Barron & Martin Giurfa
The defence of a society often requires that some specialized members coordinate to repel a threat at personal risk. This is especially true for honeybee guards, which defend the hive and may sacrifice their lives upon stinging. Central to this cooperative defensive response is the sting alarm pheromone, which has isoamyl acetate (IAA) as its main component. Although this defensive behaviour has been well described, the neural mechanisms triggered by IAA to coordinate stinging have...

Data from: Do trace metals influence visual signals? Effects of trace metals on iridescent and melanic feather colouration in the feral pigeon

Marion Chatelain, Anaïs Pessato, Adrien Frantz, Julien Gasparini & Sarah Leclaire
Trace metals are chemical pollutants of prime concern nowadays given their implication in several human diseases and their noxious effects on wildlife. Previous studies demonstrated their negative (e.g. lead, cadmium) or positive (e.g. zinc) effects on body condition, immunity and reproductive success in birds. Because of their effects on bird condition, trace metals are likely to influence the production of condition-dependent plumage colours, that may be used in mate choice. In the feral pigeon Columba...

Data from: Scale dependence of the diversity–stability relationship in a temperate grassland

Yunhai Zhang, Nianpeng He, Michel Loreau, Qingmin Pan & Xingguo Han
1. A positive relationship between biodiversity and ecosystem stability has been reported in many ecosystems; however, it has yet to be determined whether and how spatial scale affects this relationship. Here, for the first time, we assessed the effects of alpha, beta and gamma diversity on ecosystem stability and the scale dependence of the slope of the diversity–stability relationship. 2. By employing a long-term (33 years) dataset from a temperate grassland, northern China, we calculated...

Data from: A new genus of horse from Pleistocene North America

Peter D. Heintzman, Grant D. Zazula, Ross D.E. MacPhee, Eric Scott, James A. Cahill, Brianna K. McHorse, Joshua D. Kapp, Mathias Stiller, Matthew J. Wooller, Ludovic Orlando, John R. Southon, Duane G. Froese, Beth Shapiro & John Southon
The extinct “New World stilt-legged”, or NWSL, equids constitute a perplexing group of Pleistocene horses endemic to North America. Their slender distal limb bones resemble those of Asiatic asses, such as the Persian onager. Previous palaeogenetic studies, however, have suggested a closer relationship to caballine horses than to Asiatic asses. Here, we report complete mitochondrial and partial nuclear genomes from NWSL equids from across their geographic range. Although multiple NWSL equid species have been named,...

Data from: Contribution of spatial heterogeneity in effective population sizes to the variance in pairwise measures of genetic differentiation

Jérôme G. Prunier, Vincent Dubut, Lounes Chikhi & Simon Blanchet
1. Pairwise measures of neutral genetic differentiation are supposed to contain information about past and on-going dispersal events and are thus often used as dependent variables in correlative analyses to elucidate how neutral genetic variation is affected by landscape connectivity. However, spatial heterogeneity in the intensity of genetic drift, stemming from variations in population sizes, may inflate variance in measures of genetic differentiation and lead to erroneous or incomplete interpretations in terms of connectivity. Here,...

Data from: Mowing exacerbates the loss of ecosystem stability under nitrogen enrichment in a temperate grassland

Yunhai Zhang, Michel Loreau, Nianpeng He, Guangming Zhang & Xingguo Han
Summary: 1. Global reactive nitrogen (N) is projected to further increase in the coming years. Previous studies have demonstrated that N enrichment weakens the temporal stability of ecosystem primary productivity through decreased biodiversity and species asynchrony. Mowing is a globally common practice in grasslands; and infrequent mowing can maintain or increase plant diversity under N enrichment conditions. However, it is unclear how infrequent mowing affects ecosystem stability in the face of N enrichment. 2. By...
