We investigated the relative abundance of B. uluguruensis in agricultural and forested habitats at the beginning of the rainy season. This caecilian was found over a wide altitudinal range (450-1175 m a.s.l.), and in many land cover types (including natural forest, plantation forest and small scale agriculture), and different soil textures (including very compact soil). Based on quantitative and semi-quantitative surveys, B. uluguruensis is more abundant than any other subterranean lower vertebrate in this area, with densities up to 0.4 individuals m(-2) in some agricultural plots. The hypothesis proposed, that B. uluguruensis is more abundant in agriculture than their native forest, could not be conclusively tested during this brief visit, although the data that were collected do not indicate to the contrary. Likewise, the size of animals from forest and agricultural populations could not be objectively compared. specialized biodiversity surveys subterranean predators population density 080 44 1 6-13 2006 0141-6707 https://www.documentation.ird.fr/hor/fdi:010035606 10.1111/j.1365-2028.2006.00569.x 0141-6707 [F B010035606] https://www.documentation.ird.fr/hor/fdi:010035606 https://www.documentation.ird.fr/intranet/publi/2006/04/010035606.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2006-05-05 2017-08-23 fdi:010035606 fre
