Couverture géographique

A total of 115 and 50 sampling sites were set up in the São Tomé and Príncipe Islands, respectively. Sampling covered all the predominant land-use types of both islands.

Couverture taxonomique

São Tomé and Príncipe islands comprise six and four insectivorous bats, respectively. Taphozous mauritianus E. Geoffroy, 1818 and Hipposideros ruber (Noack, 1893) are found on both São Tomé and Príncipe islands. Macronycteris thomensis (Bocage, 1891) is endemic to São Tomé, while Pseudoromicia principis (Juste, Torrent, Méndez-Rodríguez, Howard, García-Mudarra, Nogueras & Ibáñez, 2023) is endemic to Príncipe. Miniopterus newtoni Bocage, 1889 is endemic to both islands. Additionally, Chaerephon Dobson, 1874 and Chaerephon pumilus (Cretzschmar, 1826) are found on São Tomé, with Chaerephon pumilus also present on Príncipe.

Données sur le projet

The overall goal of TROPIBIO is to expand the research and innovation potential of CIBIO-Research Centre in Biodiversity and Genetic Resources, through the creation of an ERA Chair in Tropical Biodiversity and Ecosystem Research. Through this initiative, the project aims to build capacity to develop excellent research that fosters innovation, thereby contributing to the conservation and sustainable use of biodiversity and ecosystems and ultimately to sustainable socioeconomic development and poverty reduction in African countries. Taking advantage of historical and cultural links, the project is rooted in a network of TwinLabs, which are partnerships established with institutions from Portuguese-speaking African countries to jointly develop research, advanced training and capacity building.

Méthodes d'échantillonnage

Acoustic surveys targeting insectivorous bats were carried out between August and September 2022, during the dry season. Sampling sites were stratified according to the availability of different land-use types to ensure representation of each major land-use type present on both islands. In total, 115 sites on São Tomé Island and 50 sites on Príncipe Island were surveyed. Each site was monitored using one AudioMoth recorder, programmed to record for one minute every five minutes over two consecutive days and nights, resulting in a total of 240 minutes of active recording per day.

Description des étapes de la méthode:

1. Each sampling site was surveyed by deploying one Audio Moth recorder programmed to record for one minute every five minutes, for two consecutive days and nights, at mid-gain with a 384 kHz sample rate, resulting in a total of 240 minutes of active recording per day. Diurnal recording was intended to capture the diurnal activity of Hipposideros ruber. Recorders were attached to an available vertical structure, between 1.5 and 2 m above the ground. Spatially contiguous sampling sites were at least 250 m apart from each other, to minimize simultaneously recording the same individual. A total of 20 spatially aggregated sampling sites were surveyed at the same time.
