摘 要:Objective:To document movement patterns,home range,nesting behaviour and social organization of 5 individuals(3 males and 2 females) of a common species of tree-shrew,Tupaia glis(T.glis) surrounding houses of otoacariasis cases.Methods:Each shrew was fitted with a transmitter chip radio-collar which operates between the frequencies of 154.13 MHz to 154.21 MHz.Each transmitter was then tracked with a Portable Telemetry Receiver(Sirtrack,New Zealand) fitted with a 3-element Yagi antenna.Collared shrews were located using standard methods of ground-based triangulation.Each location was taken from at least 2 directional fixes and a minimum of 3 compass bearings.Fixes were taken hourly for each collared individual from the time of emergence from nest(beginning of activity) till time of entry into the nest(end of activity) every day for 5 to 7 continuous days.Three series of radio telemetry observations were carried out.The bearings,time and positions of an observer were recorded and later plotted on a graph paper in order to derive coordinates of the collared animal.[These coordinates then analyzed using Ecological Software Solutions(Biotas Version 1.03)].Results:Nests were found in a jack fruit tree,long bushes,and 2 houses.Daily telemetry detections demonstrated 2 individuals of different sex having nests(or a nest) in the same house.All shrews emerged from and returned to their nests between 0601 to 0659 hours and 1901 to 1959 hours,respectively. Both the time of exit from and entry into nest were the same between sexes(P】0.05).Their average total active period was 4.90 to 7.00 hours with a total daily travel distant of 270 m to 382 m.A male and a female shrew can move as far as 3 285 m and 4 591 m,respectively.Active movements of T.glis were during daytime.They regularly entered some houses in the area during day and night except for one individual which visited during daytime only.The sizes of home range and core area for the shrews were 2.00-3.40 ha and 0.05-0.42 ha,respectively.Generally, the mean home rangeObjective:To document movement patterns,home range,nesting behaviour and social organization of 5 individuals(3 males and 2 females) of a common species of tree-shrew,Tupaia glis(T.glis) surrounding houses of otoacariasis cases.Methods:Each shrew was fitted with a transmitter chip radio-collar which operates between the frequencies of 154.13 MHz to 154.21 MHz.Each transmitter was then tracked with a Portable Telemetry Receiver(Sirtrack,New Zealand) fitted with a 3-element Yagi antenna.Collared shrews were located using standard methods of ground-based triangulation.Each location was taken from at least 2 directional fixes and a minimum of 3 compass bearings.Fixes were taken hourly for each collared individual from the time of emergence from nest(beginning of activity) till time of entry into the nest(end of activity) every day for 5 to 7 continuous days.Three series of radio telemetry observations were carried out.The bearings,time and positions of an observer were recorded and later plotted on a graph paper in order to derive coordinates of the collared animal.[These coordinates then analyzed using Ecological Software Solutions(Biotas Version 1.03)].Results:Nests were found in a jack fruit tree,long bushes,and 2 houses.Daily telemetry detections demonstrated 2 individuals of different sex having nests(or a nest) in the same house.All shrews emerged from and returned to their nests between 0601 to 0659 hours and 1901 to 1959 hours,respectively.
