All taxa biodiversity inventory of the Bois de Bouis estate (Var, France): a 10-year public-private partnership.

Background: This data paper describes the results of a 10-year scientific investigation of a biodiversity-rich private golf estate in south-eastern France in partnership with PatriNat (Office français de la biodiversité/Centre national de la recherche scientifique/Muséum national d'Histoire naturelle, Institut de Recherche pour le Développement). In total, 3,160 species and subspecies, including 1,796 arthropods and 1,049 flora, were inventoried and 65 habitat types were surveyed and mapped. This project is the first All taxa biodiversity inventory (ATBI) in a private property in France with all information available in open data. New information: The 20 datasets of fauna, flora, lichens and habitat types from the Bois de Bouis estate are now publicly available. Between 2012 and 2022, more than 22,000 occurrences were recorded, checked and published in the INPN information system. All this information is available in open access in the French portal OpenObs, operated by PatriNat and in the Global Biodiversity Information Facility (GBIF). This data paper provides an overview of the project, its main results and its contribution to the French National Inventory of Natural Heritage (INPN).This data paper presents a list eight species never previously recorded to France; three Hymenoptera: Charitopesleucobasis Townes, 1983 (Ichneumonidae), Dryinustussaci Olmi, 1989 (Dryinidae) and Sparasionmunitus Kozlov & Kononova, 1990 (Sparasionidae) and five Diptera: Clusiodesapicalis (Zetterstedt, 1848) (Clusiidae), Dicraeusvagans (Meigen, 1838) (Chloropidae), Stilponintermedius Raffone, 1994, Stilponsubnubilus Chvala, 1988 and Tachydromiaundulata (Strobl, 1906) (Hybotidae).It also includes a table comparing the project to 18 All-taxa biodiversity inventories in France and Belgium and published for the first time.

The influence of low intensities of light pollution on bat communities in a semi-natural context.

Anthropogenic light pollution is an increasingly significant issue worldwide. Over the past century, the use of artificial lighting has increased in association with human activity. Artificial lights are suspected to have substantial effects on the ecology of many species, e.g., by producing discontinuities in the territories of nocturnal animals. We analyzed the potential influence of the intensity and type of artificial light on bat activity in a semi-natural landscape in France. We used a species approach, followed by a trait-based approach, to light sensitivity. We also investigated whether the effect of light could be related to foraging traits. We performed acoustic surveys at sites located along a gradient of light intensities to assess the activity of 15 species of bats. We identified 2 functional response groups of species: one group that was light-tolerant and one group that was light-intolerant. Among the species in the latter group that appear to be disadvantaged by lighting conditions, many are rare and threatened in Europe, whereas the species from the former group are better able to thrive in disturbed habitats such as lighted areas and may actually benefit from artificial lighting. Finally, several methods of controlling light pollution are suggested for the conservation of bat communities. Recommendations for light management and the creation of dim-light corridors are proposed; these strategies may play an important role in protecting against the impact of light pollution on nocturnal animals.
