Spatial ecology of a small arboreal ambush predator, Trimeresurus macrops Kramer, 1977, in Northeast Thailand

Abstract: 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 ac… Show more

“…The fewest resources likely exist in the hot season, coinciding with the lowest B. candidus activity. Other reptiles in northeast Thailand, including Indotestudo elongata 92 , Ophiophagus hannah 93 , Trimeresurus macrops 94 , and Python bivittatus 51 responded similarly to dry seasons. Many reptiles reduce activity during particularly hot and dry periods to conserve energy and water 95 – 98 .…”

“…The least resources likely exist in the hot season, coinciding with the least B. candidus activity. Other reptiles in northeast Thailand, including Indotestudo elongata , (Ward et al, 2021), Ophiophagus hannah (Marshall et al, 2020), Trimeresurus macrops (Strine et al, 2018), and Python bivittatus (Smith et al, 2021) responded similarly to dry seasons. Many reptiles reduce activity during particularly hot and dry periods to conserve energy and water (Christian and Green, 1994; Christian et al, 1995, 2007; Peterson, 1996; Loehr, 2012).…”

“…Doherty et al [ 9 ] suggested that reduced movement by Eastern Bearded Dragons ( Pogona barbata ) was partly driven by higher prey availability in linear vegetation patches. Although we lack direct evidence suggesting semi-natural areas within agricultural landscapes host relatively higher prey abundance, it is likely King Cobra prey can be found more frequently where vegetation and water are present [ 30 , 97 , 98 ]. However, increased movements in forests, at least for some individuals, may indicate that resource availability alone fails to explain variation in movement patterns.…”

“…The transitional zone also contains 159 villages and a four-lane highway that connects Nakhon Ratchasima to Bangkok. Further descriptions of the study site can be found in Silva et al [ 28 ] and Marshall et al [ 25 , 29 , 30 ].…”
