红耳龟在广东古田保护区的家域研究

Home Range of Trachemys scripta elegans in Gutian Nature Reserve,Guangdong Province

于2010年9月至2012年6月,在广东古田保护区内利用无线电遥测技术,对保护区内21只红耳龟的家域进行研究。结果表明:红耳龟家域为5.25 hm2±8.66 hm2,核域为1.26 hm2±1.73 hm2。红耳龟的家域和核域面积在繁殖期显著大于非繁殖期,雄性的在繁殖期显著大于非繁殖期,雌性的在繁殖期和非繁殖期无显著性差异,但在繁殖期大于非繁殖期。雄性的和核域在繁殖期显著大于雌性,在非繁殖期不存在显著性差异,但雄性的都大于雌性的。家域大小与其身体大小之间没有显著相关性。

The home range of 21 Trachemys scripta elegans individuals were studied via radio-telemetry from September 2010 to June 2012 in Gutian Provincial Nature Reserve,Guangdong Province.The results showed that the mean home range of turtles was 5.25 hm2± 8.66 hm2,and mean home range core was 1.26 hm2± 1.73 hm2.The home range and home range core of the turtles in breeding season（especially the male turtles） were significantly larger than those in non-breeding season.Additionally,in breeding season,the home range and home range core of male turtles were significantly larger than those of females.However,no significant difference was observed in non-breeding season between genders.There were also no significant correlations between the home range and body sizes.
