We describe the home range and movements of a population of in Tonatico, Estado de México, México, over 3.5 years (during rainy and dry season months) using radiotelemetry in 37 adult turtles. The results showed that the home range of was 0.151 ± 0.051 ha using 50% kernel density estimator (KDE), and 0.657 ± 0.214 ha using 95% KDE; the home range did not vary between sexes. showed low distances traveled 51.44 ± 4.50 m, where 87.3% ( = 373) of movements were <100 m. The distance traveled differed by season, and movement category (aquatic and terrestrial movements). The shortest distance occurred during the dry season, during which some individuals move to estivation sites, and these movements were shorter than movements to artificial ponds (cattle ponds). In this population, home range and movement are similar to other species of the genus . Overall, the results indicate than are highly dependent on aquatic habitats, but also utilize the terrestrial habitats for different biological activities, and to maintain viable populations. Therefore, the conservation of the entire inhabited area is fundamental. This study highlights the need to increase the studies, in Central México, concerning habitat use of freshwater turtles in order to increase the efficiency of conservation strategies.
我们使用无线电遥测技术，对墨西哥州托纳蒂科的一群[具体物种未给出]成年龟在3.5年时间里（包括雨季和旱季月份）的活动范围和移动情况进行了描述。结果显示，使用50%核密度估计（KDE）时，[具体物种未给出]的活动范围为0.151±0.051公顷，使用95% KDE时为0.657±0.214公顷；活动范围在性别之间没有差异。[具体物种未给出]移动的距离较短，为51.44±4.50米，其中87.3%（n = 373）的移动距离<100米。移动距离因季节和移动类别（水生和陆生移动）而有所不同。最短距离出现在旱季，在此期间一些个体前往夏眠地点，这些移动比前往人工池塘（牛塘）的移动距离短。在这个种群中，活动范围和移动情况与该属的其他物种相似。总体而言，结果表明[具体物种未给出]高度依赖水生栖息地，但也利用陆地栖息地进行不同的生物活动，并维持种群的生存能力。因此，保护整个栖息地至关重要。本研究强调有必要在墨西哥中部增加关于淡水龟栖息地利用的研究，以提高保护策略的效率。
