Annual induced fires have caused significant changes in the composition and structure of wildlife globally. These events are particularly critical for species with limited mobility and small clutch sizes, such as small and medium-sized freshwater turtles in the tropics. At the same time, this topic has received little attention and has not been documented in countries with a high diversity of freshwater turtles, such as Mexico. In this study, we report the mortality of the red-cheeked mud turtle (Kinosternon scorpioides cruentatum) and the Pacific Coast musk turtle (Staurotypus salvinii) caused by a fire in the north portion of the municipality of Suchiate, Chiapas, Mexico. Specifically, our aims were to (1) register the plant species where the turtles occurred, (2) determine the population structure of each turtle species, and (3) estimate the density, size, and sex ratio of the dead turtles of each species. Additionally, we discuss the potential effects of fire on the demography of these turtles in the study site.

每年引发的火灾导致全球野生动物的组成和结构发生重大变化。这些事件对于活动能力有限和窝数较小的物种尤其重要，例如热带地区的中小型淡水龟。与此同时，这个话题很少受到关注，也没有在墨西哥等淡水龟多样性较高的国家进行记录。在这项研究中，我们报告了墨西哥恰帕斯州苏奇亚特市北部火灾造成的红颊泥龟（Kinosternon scorpioides cruentatum）和太平洋海岸麝香龟（Staurotypus salvinii ）的死亡。具体来说，我们的目标是（1）登记海龟出现的植物物种，（2）确定每个海龟物种的种群结构，以及（3）估计每个物种死亡海龟的密度、大小和性别比。此外，我们还讨论了火灾对研究地点这些海龟数量的潜在影响。
