Analysis of the state of conservation of the Jánano Hill, based in knowledge of its mastofauna

Abstract

This manuscript contains the characterization of the mastofauna, registered along the altitudinal gradient of Cerro Jánano, taking into account the absence-presence of functional groups and relevant species (endemic, threatened and susceptible to traffic), key to the operation and conservation of this ecosystem, for which daily samplings were carried out (morning and afternoon), applying a rapid evaluation through direct observations and indications, in addition to informal interviews with hunters. There were 29 species registered, belonging to 16 families and 7 orders. The most representative families were Didelphidae, Felidae and Procyonidae. Important reports were obtained such as the high representativeness of the dispersing species Proechimys semispinosus and Pecari tajacu, the latter being the species with the highest records (individuals and tracks) of presence from the skirt to the top of the hill. Other important reports were highlighted, such as those of Chironectes minimus and Leopardus wiedii that act as predators and controllers of other prey populations. The presence of Alouatta palliata near the hill was also proven, evidencing the existence of connectivity in the area. Four threatened species were identified and nine were susceptible to traffic. All these species give the ecosystem great relevance, corroborating its good state of conservation.
