Data from: Dispersal in the sub-Antarctic: king penguins show remarkably little population genetic differentiation across their range

Background: Seabirds are important components of marine ecosystems, both as predators and as indicators of ecological change, being conspicuous and sensitive to changes in prey abundance. To determine whether fluctuations in population sizes are localised or indicative of large-scale ecosystem change, we must first understand population structure and dispersal. King penguins are long-lived seabirds that occupy a niche across the sub-Antarctic zone close to the Polar Front. Colonies have very different histories of exploitation, population...

Data from: Root functional parameters predict fine root decomposability at the community level

Iván Prieto, Alexia Stokes & Catherine Roumet
1. Root quality is one of the main drivers of fine root decomposition, an important process controlling soil carbon (C) and nutrient cycling in most terrestrial ecosystems. Root quality is defined by chemical and morphological traits, which differ across species and thus communities. This trait variation is assumed to follow a trade-off between resource acquisition and conservation (i.e. the root economics spectrum). To what extent root quality or the economics spectrum influence fine root decomposition...

Data from: Lifespan and reproductive cost explain interspecific variation in the optimal onset of reproduction

Fitness can be profoundly influenced by the age at first reproduction (AFR), but to date the AFR-fitness relationship only has been investigated intraspecifically. Here we investigated the relationship between AFR and average lifetime reproductive success (LRS) across 34 bird species. We assessed differences in the deviation of the Optimal AFR (i.e., the species-specific AFR associated with the highest LRS) from the age at sexual maturity, considering potential effects of life-history as well as social and...

Data from: Environmental heterogeneity and population differences in blue tits personality traits

Gabrielle Dubuc-Messier, Denis Reale, Philippe Perret & Anne Charmantier
Environmental heterogeneity can result in spatial variation in selection pressures that can produce local adaptations. The pace-of-life syndrome hypothesis predicts that habitat-specific selective pressures will favor the coevolution of personality, physiological, and life-history phenotypes. Few studies so far have compared these traits simultaneously across different ecological conditions. In this study, we compared 3 personality traits (handling aggression, exploration speed in a novel environment, and nest defense behavior) and 1 physiological trait (heart rate during manual...

Data from: Competitor relatedness, indirect soil effects and plant co-existence

Bodil K. Ehlers, Patrice David, Christian F. Damgaard & Thomas Lenormand
How species co-exist is a central question in ecology. Niche differentiation can prevent two species from excluding each other by competition. However, this interaction can vary in space because of internal factors such as intraspecific genetic variation, or external ones such as the presence of a third species. While these effects have been repeatedly observed, their joint effect on the outcome of competition has rarely been considered. We experimentally investigated how a dominant ecosystem engineer...

Data from: Potential for coupling the monitoring of bush-crickets with established large-scale acoustic monitoring of bats

Stuart E. Newson, Yves Bas, Ashley Murray & Simon Gillings
1. Monitoring biodiversity over large spatial and temporal scales is crucial for assessing the impact of global changes and environmental mitigation measures. However, large-scale monitoring of invertebrates remains poorly developed despite the importance of these organisms in ecosystem functioning. Exciting possibilities applicable to professional and citizen science are offered by new recording techniques and methods of semi-automated species recognition based on sound detection. 2. Static broad-spectrum detectors deployed to record throughout whole nights have been...

Data from: The effects of archipelago spatial structure on island diversity and endemism: predictions from a spatially-structured neutral model

Fanny Gascuel, Fabien Laroche, Anne-Sophie Bonnet-Lebrun & Ana S. L. Rodrigues
Islands are particularly suited to testing hypotheses about the ecological and evolutionary mechanisms underpinning community assembly. Yet the complex spatial arrangements of real island systems have received little attention from both empirical studies and theoretical models. Here, we investigate the extent to which the spatial structure of archipelagos affects species diversity and endemism. We start by proposing a new spatially-structured neutral model that explicitly considers archipelago structure, and then investigate its predictions under a diversity...
