4. História natural de Mazama bororo (Artiodactyla; Cervidae) através de etnozoologia, monitoramento fotográfico e rádio-telemetria. / Natural history of mazama bororo in the atlantic rain forest obtained through ethnozoology, photographic monitoring and telemetry.
The species Mazama bororo was proposed in 1996 based on the unique karyotype (2n=32-34) found in some captive animals. The present study began in 1998 and intended to confirm the occurrence of this species in nature as well as to develop deer capture methods adequate in forest environments and to obtain basic ecological information using etnozoological appro
