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 range size of females was 20.8%larger than that of males.Females covered a 15.4%slightly higher daily movement range compared to males.Conclusions:This is the first radio telemetry study in Malaysia to monitor movements and home range of shrews carrying ticks on their body.It demonstrates that shrews are potential carriers of ticks from wild into the houses and their compounds based on their total active periods spent moving around from fruit orchards, secondary forest,plantations and other vegetations to trees in compound of 4 to 7 houses and vice versa.There are also evidences showing shrews have close contact with humans.展开更多

It shows that the system has a good performance and suitable for short range climate modeling. The model simulates well the monthly mean, pentad mean and daily field, pentad mean and daily field and can depict more details than coarse resolution analyses. Weather systems and information can pass into and out of the model domain through lateral boundaries without notable damping. Almost all of the weather and climate changes can be reflected in the simulation, in which both the changing tendencies, amplitudes, speeds, and phases are consistent with the real cases. The simulated precipitation is much close to the observed one, both in the extent, position and in the intensity of rainfall. In addition, some smaller precipitation centers could also be reflected in the simulation.展开更多
