RESUMEN
Many factors influence microhabitat including climate and the occurrence of predators, prey and suitable shelters. The influence of predators in a semi-extensive breeding system is minimized due to frequent monitoring of the area. This situation enables the independent analysis of such other variables as refuges and temperature. Some specimens of the Viperidae family are kept in a semi-extensive breeding system at the Butantan Institute for display and study. These animals are widely distributed in the Atlantic Forest and Cerrado, two biomes with distinct climatic characteristics. We compared the daily activity pattern and microhabitat use of the species Bothrops jararaca and Crotalus durissus terrificus. Our main questions were whether rattlesnakes and lancehead snakes respond to habitat selection differently in similar climatic conditions and if they choose similar microhabitats. Species of the genus Bothrops were frequently found under shelters regardless of the time of day. On the other hand, snakes of the genus Crotalus were frequently found sheltered during the early morning, then migrated to sunnier areas and returned to shelters in late afternoon.

E apresentado um caso de reparacao do labio superior pos-excisao tumoral em que e utilizada a tecnica de Estlander adjuvada por um retalho miomucoso para reparacao do defeito resultante. Apos breve revisao bibliografica, e descrito o procedimento, devidamente documentado com esquemas e fotografias. Os autores concluem que o prolongamento miomucoso introduzido na tecnica original de Estlander fornece bons resultados esteticos e funcionais, referindo apenas o incoveniente de um segundo tempo para confeccao de nova comissura
