Amount of semi‐natural habitats (permanent grasslands, woodlands and hedgerows) and their level of fragmentation are among the main determinants of wild bee diversity in agricultural landscapes. However, their impact on the distribution of bee ecological traits has received little attention. In this study, we aimed to explore whether changes in the distribution of bee ecological traits along gradients of habitat amount and fragmentation were due to a direct effect of landscape context on multiple traits (‘response traits’) or to a correlation of response traits with other ecological traits not involved in the response of bee species to landscape context. In two study regions in southwest Fra..View full abstract

RC received a PhD scholarship from the French Ministry of Higher Education and Research (Univ. de Toulouse). Field work in France was carried out as part of FarmLand, an ERA-Net BiodivERsA project funded by the French National Research Agency (ANR-11-EBID-0004). In Australia, financial support was provided by the Paddy Pallin Foundation in partnership with the Royal Zoological Society of NSW, the WildCountry Science Council, and an Australian Postgraduate Award and CSIRO scholarship to PL. ML was supported by the TULIP Laboratory of Excellence (ANR-10-LABX-41). We thank D. Genoud and M. Batley for their help on specimen identification and their expertise on bee species traits. We thank M. Kuhlmann and V. Le Feon for the provision of part of the French trait data. We also thank the farmers from France and Australia who allowed us to work in their fields, all the people involved in the field surveys and specimen identification, technical staff, colleagues and volunteers: L. Frontero, B. Dumora, A. Bourgeade, R. Rudelle and F. Calatayud, C. Singh, Z. Pujol, A-S. Larcebeau and R. Bertram (France) and M. Castles, M. Long, L. Lentini, A. Munro, B. Noel, K. Russell and J. Stanaway (Australia). We also thank the three anonymous reviewers for their helpful comments.
