Amphibians are organisms which mainly have a biphasic life cycle. When at the larval stage, their habitat is generally aquatic, and when adults, they become terrestrial. Pond-breeding amphibians are sensitive to some disturbances in their environment which lead to the decline of a population. The interactions between the species and their environment are performed through movement. Movement ecology combines and explains the movement data of organisms with biotic and abiotic factors and because of this, knowing the movement of these creatures is of great ecological importance. We used the spool-and-line methodology in individuals of the treefrog Phyllomedusa burmeisteri, at the Reserva Ecologica Michelin, located in the southern region of Bahia in Brazil to study their movement patterns in different environments inside and outside of the forest. We monitored 19 P. burmeisteri individuals that presented a mean total movement distance of 2160.76 cm (S.D. 1152.42). We found no significant difference in the trajectories of individuals in forested and open areas, as well as a positive relationship between the distances individuals moved and their weight only in forested areas. no relationship between distance and weight of these individuals. We observed that individuals followed non-linear paths and the number of steps from one place to another varied among individuals. Our movement ecology data allows us to answer questions about short-term movement patterns of Phyllomedusa burmeisteri. This is the first step to start understanding the spatial cognition of treefrogs from the Atlantic Forest and to fill gaps about life habits of these frogs. Information on the movement patterns of a species, as well as its home range can help to create conservation strategies, regarding the creation or delimitation of protected areas, for example.
两栖动物主要具有双相生活史。在幼虫阶段,它们的栖息地通常是水生的,而在成体阶段,它们变成了陆生的。池塘繁殖的两栖动物对其环境中的一些干扰很敏感,这些干扰会导致种群数量下降。物种与其环境之间的相互作用是通过运动来实现的。运动生态学将生物和非生物因素的生物体运动数据结合并解释,因此,了解这些生物的运动具有重要的生态意义。我们在巴西巴伊亚南部地区的米其林生态保护区使用卷轴和线方法对树蛙 Phyllomedusa burmeisteri 的个体进行了研究,以研究它们在森林内外不同环境中的运动模式。我们监测了 19 只 P. burmeisteri 个体,它们的总运动距离平均为 2160.76 厘米(标准差为 1152.42)。我们发现,个体在森林和开阔地区的轨迹没有显著差异,只有在森林地区,个体移动的距离与其体重之间呈正相关,而在森林地区则没有这种关系。个体的体重与体重之间没有关系。我们观察到个体遵循非线性路径,从一个地方到另一个地方的步数因人而异。我们的运动生态学数据使我们能够回答有关 Phyllomedusa burmeisteri 短期运动模式的问题。这是开始从大西洋森林理解树蛙的空间认知并填补有关这些青蛙生活习性的空白的第一步。有关物种运动模式及其活动范围的信息可以帮助制定保护策略,例如创建或划定保护区。
