摘要

尽管社区生态保护区具有相关性,但人们对这些保护区时空生物多样性模式的变化知之甚少。在这里,我们分析了墨西哥恰帕斯州Bajlum Pakal社区生态保护区内4种不同环境(原始森林、河岸植被、次生林和牧场)中甲虫群落的时空动态。我们发现,所分析的环境之间的空间动力学存在差异,热带雨林和河岸植被的多样性更高。时间动态与物种的丰富度和多样性没有关系;因此,空间动力学对于解释甲虫在各种环境中的多样性更为重要。在评估空间周转时,我们发现β多样性最重要的组成部分是β2(环境之间),这表明环境的巨大空间异质性所提供的环境变化调节了该保护区甲虫的多样性模式。保护策略必须考虑调节物种组合的时空动态变化,以确定它们对土地利用变化的反应。重要的是保持社区生态保护区的存在,以保护热带景观的生物多样性和连通性,以及其居民的生活质量。

Spatio-temporal variation of dung beetle (Coleoptera: Scarabaeidae) assemblages in a community ecological reserve of southeastern Mexico
Despite the relevance of community ecological reserves, little is known about changes in spatio-temporal biodiversity patterns in these reserves. Here, we analyzed the spatio-temporal dynamics of the dung beetle assemblages in 4 different environments (primary forest, riparian vegetation, secondary forest, and pasture) in the Bajlum Pakal Community Ecological Reserve, in Chiapas, Mexico. We found that the spatial dynamics showed differences among the analyzed environments, with higher diversity in the tropical rainforest and riparian vegetation. The temporal dynamics did not present a relationship with the richness and diversity of species; therefore, spatial dynamics were more important for explaining the diversity of beetles from all environments. When evaluating the spatial turnover, we found that the most important component of β diversity was β2 (between environments), which suggests that the environmental variation provided by the great spatial heterogeneity of the environments modulates the diversity patterns of beetles in this reserve. Conservation strategies must consider changes in the spatio-temporal dynamics that modulate species assemblages to determine their responses to changes in land use. It is important to maintain the existence of community ecological reserves that conserve biodiversity and connectivity in tropical landscapes, as well as the quality of life of its inhabitants.
