An understanding of the spatial ecology of species living in and around human-dominated habitats is needed to develop conflict mitigation strategies and predict how organisms cope with ongoing anthropogenic habitat alteration. Here we present the results of a six-month telemetry study in Thailand of the banded krait (Bungarus fasciatus), a venomous elapid snake. We quantified home range size and habitat use of three adult kraits (1 male, 2 females) in an agricultural habitat. The kraits travelled an average of 47.20 m ± 23.54 m between shelter sites and occupied home ranges of on average 21.45 ha ± 19.56 ha (95 % dynamic Brownian Bridge Movement Models). They preferred to seek day time refuge amongst less disturbed habitat features, including waterways and rice paddy dykes, while avoiding routinely disturbed monoculture fields. The two female kraits also exhibited reduced movement while simultaneously attending their nests in a shared burrow complex. Fifteen neonates were observed emerging from the nest site. We recommend further investigation of banded krait reproductive ecology and ability to persist in heavily disturbed habitats.

The Big-Eyed Green Pit Viper (Trimeresurus macrops; Kramer, 1977) is a venomous snake species endemic to Southeast Asia. Although we have some knowledge of the systematics and toxicology ofT. macrops, little is known about the spatial ecology of this species. From May 2013 to February 2014, we used radio-telemetry to determine home-range sizes of 13 adult femaleT. macropsinhabiting the Sakaerat Biosphere Reserve in Northeast Thailand. We found that individual home ranges forT. macropsaveraged 0.175 ha, with activity areas ranging from 0.112-0.303 ha and core areas ranging from 0.023-0.052 ha. There was little overlap between conspecific tracked females, especially for the most used areas of their home ranges. We find thatT. macropsambushes more in higher humidity and expresses very little diurnal activity. They use the groundstory for ambushing, then retreat over small distances to higher refuge during the day. Future studies should focus on prey abundance, habitat selection, and survival rates.
