Data from: Symbolic representation of numerosity by honeybees (Apis mellifera): matching characters to small quantitiesScarlett Howard, Aurore Avarguès-Weber, Jair Garcia, Andrew Greentree & Adrian Dyer
The assignment of a symbolic representation to a specific numerosity is a fundamental requirement for humans solving complex mathematical calculations used in diverse applications such as algebra, accounting, physics, and everyday commerce. Here we show that honeybees are able to learn to match a sign to a numerosity, or a numerosity to a sign and subsequently transfer this knowledge to novel numerosity stimuli changed in colour properties, shape, and configuration. While honeybees learnt the associations...
Community assembly theory assumes that ecological communities are spatially delimited into patches. Within these patches, coexistence results from environmental filtering, competition, and immigration. Truly delineated communities exist in laboratory studies of microbial cultures in Petri dishes, yet empirical tests conducted in continuous environments often use patches defined by convention as opposed to realised boundaries. Here we perform a test of ecological community assembly rules using foliar endophyte communities from a tropical rainforest, where leaves are...
Data from: Beyond dispersal versus philopatry? Alternative behavioural tactics of juvenile roe deer in a heterogeneous landscapeDelphine Ducros, Nicolas Morellet, Rémi Patin, Kamal Atmeh, Lucie Debeffe, Bruno Cargnelutti, Yannick Chaval, Bruno Lourtet, Aurélie Coulon & A. J. Mark Hewison
Although inter-individual heterogeneity in many aspects of dispersal behaviour is widely reported, this key life-history trait is predominantly modelled as a dichotomous state of philopatry vs. dispersal. The increasing body of evidence for dispersal syndromes (i.e. a suite of correlated morphological, behavioural, and life-history traits associated with dispersal) implies substantial but, to date, undocumented individual heterogeneity in behavioural tactics during dispersal. Using a large sample (N = 154) of GPS monitored juvenile roe deer (Capreolus...
Data from: RAD‐sequencing for estimating genomic relatedness matrix‐based heritability in the wild: a case study in roe deerLaura Gervais, Charles Perrier, Maria Bernard, Joël Merlet, Josephine M. Pemberton, Benoit Pujol & Erwan Quemere
Estimating the evolutionary potential of quantitative traits and reliably predicting responses to selection in wild populations are important challenges in evolutionary biology. The genomic revolution has opened up opportunities for measuring relatedness among individuals with precision, enabling pedigree-free estimation of trait heritabilities in wild populations. However, until now, most quantitative genetic studies based on a genomic relatedness matrix (GRM) have focused on long-term monitored populations for which traditional pedigrees were also available, and have often...
La fabrique des corps sexués, entre médicalisation et pathologisation. La place du corps dans les trans studies en FranceAnastasia Meidani & Arnaud Alessandrin

Plant diversity is an important driver of diversity at other trophic levels, suggesting that cascading extinctions could reduce overall biodiversity. Most evidence for positive effects of plant diversity comes from grasslands. Despite the fact that forests are hotspots of biodiversity, the importance of tree diversity, in particular its relative importance compared to other management related factors, in affecting forest‐associated taxa is not well known. To address this, we used data from 183 plots, located in...
