We evaluated the annual activity cycle of Nytophilus gouldi and N. geoffroyi using 82 nights of mist-netting data from a site near Armidale in northern NSW. Our purpose was to assess whether these bats hibernated or used short bouts of daily torpor combined with foraging on at least some nights. During the cold months of the year (May - August) bat activity levels inferred from net captures was very low providing support for the hypothesis that these bats use daily torpor and at least sometimes actively forage as opposed to entering hibernation.

This study aimed at describing daily and seasonal variation in the activity of a population of South-American rattlesnakes (Crotalus durissus) in a savanna like habitat (Cerrado) in Southeastern Brazil. Seasonal and daily activities of snakes were evaluated by the number of captures of snakes during road surveys, accidental encounters, and relocations by radio-tracking. Our results show that climatic variables such as air temperature and rainfall have little influence on the activity pattern of rattlesnakes. Our findings indicate that rattlesnakes spend most of the day resting and most of the night in ambush posture. The South-American rattlesnake is active throughout the year with a discrete peak in activity of males during the matting season. The possibility of maintaining activity levels even during the coldest and driest season can facilitate the colonization of several habitats in South America. This possibility currently facilitates the colonization of deforested areas by rattlesnakes.
