摘要我们报道了在墨西哥哈利斯科沿海热带森林中对墨西哥斑点木龟(Rhinoclemmys Ruida Perixantha)的野外研究结果。我们使用实地调查、跟踪线轴和无线电遥测来调查活动模式，用三种不同的技术估计栖息地的大小，并开发出一个通用的线性模型来识别与黄毛虫栖息地相关的特征。研究发现，乌龟活动最频繁的时间是正午，活动高峰出现在0900~1500h。与雨季(6月下旬~9月)相比，在旱季(1~6月中旬)，黄斑龟的活动减少(活动减少，活动距离缩短)。在我们比较的三种方法中，栖息地的大小没有差异，所有的估计都表明，黄毛鼠的栖息地较小，雄性的栖息地比雌性的大。海龟利用的地点与落叶和木质碎屑、草本植物、植被、藤状灌木和坡地呈正相关，与裸露地面呈负相关。我们的发现可以用来加强未来对黄花龙和其他陆生土豆的保护工作。
Abstract We report the results of a field study on Mexican Spotted Wood Turtles (Rhinoclemmys rubida perixantha) in a seasonally dry tropical forest of coastal Jalisco, Mexico. We used field surveys, trail spools, and radio telemetry to investigate activity patterns, estimate home range size with three different techniques, and develop a generalized linear model to identify features associated with habitats used by R. r. perixantha. We found that turtles were most frequently active at midday, with peak activity occurring from 0900 to 1500 h. During the dry season (January–mid-June), R. r. perixantha showed reduced activity (fewer movements and shorter travel distances) compared to the wet season (late June–September). Home range size did not differ among the three methods we compared, and all estimates revealed that R. r. perixantha have small home ranges, with males having larger home ranges than females. Sites used by turtles were positively associated with leaf litter and woody debris, herbaceous plants, vegetation, vine-like shrubs, and sloped terrain, and negatively associated with bare ground. Our findings can be used to strengthen future conservation efforts for R. r. perixantha, as well as other terrestrial geoemydids.
