摘要

森林栖息地的破坏造成了极其分散的区域和植被结构的变化。这改变了微栖息地的特征和资源的可用性,并影响了蚂蚁等动物物种的多样性,蚂蚁是一个具有重要生态作用的大型群体。当蚂蚁在树木和灌木上觅食时,植被结构会影响这些生物的存在。季节性等非生物因素也会影响蚂蚁群落的多样性。在此基础上,本研究旨在调查不同季节以植物为食的蚂蚁物种的多样性分布。这项研究是在大西洋森林的八片次生林中进行的。我们使用多样性的加性划分、β多样性的划分和典型对应分析来衡量季节性和植被结构对蚂蚁物种多样性分布的影响。雨季对以植物为食的蚂蚁的多样性产生了积极影响。灌木的组成在雨季受灌木叶密度的影响,在旱季受树木周长的影响。每个碎片都保存了不同的蚂蚁物种库,植被结构对蚂蚁多样性产生了积极影响。这些结果突出了保护大部分森林碎片的重要性,以更好地保护区域内的蚂蚁种群。

Effects of Vegetation Structure on Ant Diversity in Different Seasonal Periods in Impacted Fragments of Atlantic Forest
The destruction of forest habitats generates extremely fragmented areas and changes in vegetation structure. That changes the characteristics of microhabitats and the availability of resources and affects the diversity of animal species such as ants, which are a large group with an important ecological role. As ants forage on trees and shrubs, the vegetation structure can affect the presence of these organisms. Abiotic factors such as seasonality can also influence the diversity of the ant community. Based on that, this study aimed to investigate the distribution of the diversity of ant species that forage on plants in different seasonal periods. The study was carried out in eight secondary forest fragments of the Atlantic Forest. We used additive partitioning of diversity, partitioning of β diversity and canonical correspondence analysis to measure the effect of seasonality and vegetation structure on the distribution of ant species diversity. The rainy season positively influences the diversity of ants that forage on plants. Composition was affected by shrub leaf density in the rainy season and by tree circumference in the dry. Each fragment preserved a different pool of ant species, and the vegetation structure positively influenced ant diversity. These results highlight the importance of conserving the majority of forest fragments to better preserve the pool of ant species regionally.

期刊介绍: SOCIOBIOLOGY publishes high quality articles that significantly contribute to the knowledge of Entomology, with emphasis on social insects. Articles previously submitted to other journals are not accepted. SOCIOBIOLOGY publishes original research papers and invited review articles on all aspects related to the biology, evolution and systematics of social and pre-social insects (Ants, Termites, Bees and Wasps). The journal is currently expanding its scope to incorporate the publication of articles dealing with other arthropods that exhibit sociality. Articles may cover a range of subjects such as ecology, ethology, morphology, population genetics, physiology, toxicology, reproduction, sociobiology, caste differentiation as well as economic impact and pest management.
