Abstract

ABSTRACT: The organization of ant communities can be affected by vegetation characteristics and by interspecific interactions. We evaluated the roles of vegetation complexity/heterogeneity and interspecific interactions on the organization of ant communities in two contrasting habitats. A total of 25 species of ants were collected in pitfall traps in the Cerrado (13 species) and in the Atlantic forest (22 species). Beta diversity (Dβ) was higher among Atlantic forest trees and the plant height positively affected the richness of ants. Greater Dβ in the Atlantic forest environment could be explained by the greater complexity of the vegetation in this environment. Co-occurrence analyses have shown that interspecific interactions are more important in shaping ant community organization in the Cerrado than in the Atlantic Forest. Low availability of resources can generate interspecific competition and competitive exclusion. Thus, the variation in resource availability could explain the results of the co-occurrence analyses. Finally, the importance of resource availability for the conservation of ant diversity is discussed.

两种对比环境下蚂蚁群落的组织：植被特征和种间相互作用的作用

摘要：蚂蚁群落的组织受到植被特征和种间相互作用的影响。我们评估了植被复杂性/异质性和种间相互作用在两个对比栖息地蚂蚁群落组织中的作用。在塞拉多（13种）和大西洋森林（22种）的陷阱中共收集了25种蚂蚁。大西洋林木的β多样性（Dβ）较高，株高对蚂蚁丰富度有正向影响。大西洋森林环境中较大的Dβ可以解释为该环境中植被的复杂性。共生分析表明，种间相互作用在塞拉多形成蚂蚁群落组织方面比在大西洋森林更重要。资源的低可用性会产生种间竞争和竞争性排斥。因此，资源可用性的变化可以解释共现分析的结果。最后，讨论了资源可利用性对蚂蚁多样性保护的重要性。

期刊介绍： Contributions are accepted on any of the aspects of systematics and taxonomy of insects. This includes: taxonomic revisions, phylogenetics, biogeography and faunistics, and descriptive morphology of insects. Taxonomic papers describing single species are acceptable if such a study is sufficiently justified, however, comprehensive studies that provide a comparative, integrated study of insect systematics and taxonomy will get priority.
