One of the most effective means of evaluating the effects of habitat loss and landscape configuration is to assess the response of bioindicators. The present study aimed to verify which parameters of ant and dung beetle communities (species richness, abundance, unbiased Shannon diversity, and turnover rates) are most useful for evaluating the relative influence of small forest patches (< 50 ha) and landscape in the tropical rainforest of Los Tuxtlas, Mexico. We recorded a total of 106 species of ants and 30 species of dung beetle. The ant and dung beetle assemblages were related in different ways to patch and landscape attributes. Hypogeic ants were more sensitive to patch attributes, particularly vegetation composition, compared to landscape attributes. Epigeic ant assemblages are likely a disturbance indicator, or the assemblages have already homogenized across the region. Arboreal ant assemblages were particularly sensitive to fragmentation and responded to within-patch vegetation and landscape configuration. Dung beetles were more sensitive to landscape composition than to patch attributes. Given these findings, the biomonitoring of ants and dung beetles should focus on both patch and landscape attributes in fragmented landscapes to maintain the different ecosystem functions provided by them.

在破碎的热带森林景观中，蚂蚁和ung甲虫组合对斑块和景观属性的反应如何可预测？

评估生境丧失和景观格局影响的最有效方法之一是评估生物指标的响应。本研究旨在验证哪些蚂蚁和甲虫群落参数（物种丰富度，丰度，无偏香农多样性和周转率）对于评估小片森林（<50公顷）和热带地区景观的相对影响最有用墨西哥洛斯图斯特拉斯的热带雨林。我们记录了总共106种蚂蚁和30种of。蚂蚁和ung甲组合以不同的方式关联以修补和景观属性。与景观属性相比，低蚂蚁对斑块属性（尤其是植被组成）更敏感。蚂蚁聚集可能是一个干扰指标，或整个地区的组织已经同质化。树栖蚂蚁组合对碎片特别敏感，并对斑块内的植被和景观配置敏感。粪甲虫对景观组成比对斑块属性更敏感。鉴于这些发现，对蚂蚁和甲的生物监测应集中于零散的景观中的斑块和景观属性，以维持它们提供的不同生态系统功能。
