Praying mantis and spider species are common food items in the diet of several anuran species. Nevertheless, in this study we report the predation of young treefrogs Osteocephalus taurinus by two spider species, a Pisauridae and a Trechaleidae (Neoctenus sp.) and by the praying mantis Eumusonia sp. in Mato Grosso, Central Brazil. The great abundance of this treefrog in the region, combined with its small body size during the juvenil stage, favor its predation by generalists predators. Indeed, more studies are needed to quantify the real influence of invertebrate predators on anuran populations. |

Abstract: The objective of this work was to estimate an index of the relative biomass per species, in a medium to large-sized mammal community, as well as to determine how the introduced wild boar (Sus scrofa) fits into this index, and to verify if the occupancy of sites by domestic dogs interferes with those of wild boars and how much the periods of dogs’ activity overlap those of wild boars. The biomass/effort index was measured for each native mammal species and for the introduced wild boar, in two surveyed farms in Brazil’s Western Atlantic Forest range, through the use of camera trappings that were also used to verify if dogs and wild boar overlap in space and activity time. Wild boars seem to dominate the community, just a few years after their... |
