Urbanization transforms natural ecosystems, creating an environmental mosaic, characterized by native vegetation sites mixed with constructed sites. In this study, we compared dung beetle taxonomic and functional diversity between residential and greenspace sites (remnants of native vegetation) in an urban landscape in the Brazilian Cerrado. We sampled dung beetles in February (2013–2014 – 2015) in four sites of remnants of native Cerado (here called “greenspace”) and four residential sites in the city of Aquidauana, Mato Grosso do Sul, Brazil. Greenspace sites are characterized by a mixture of plants of two distinct strata (phytophysiognomy Cerrado sensu stricto), a woody layer of trees and large shrubs, while residential sites are characterized by residential buildings (housing and commercial sites), unpaved roads with tree-lined streets. Dung beetle abundance and species richness were higher in greenspace sites. Species composition differed significantly among habitats but functional composition did not differ. Functional dispersion and functional richness was higher in greenspace sites. On the other hand, functional evenness was similar between greenspace and residential sites. In this study, we found higher taxonomic and functional components of dung beetle diversity in greenspace when compared to residential sites in the Brazilian Cerrado. Thus, we highlight the importance greenspace sites for the conservation of dung beetle biodiversity and consequently their ecological services (i.e. such as soil aeration, secondary seed dispersal, parasite regulation), which indirectly can affect human life quality in the urban matrix.

绿地保护了巴西Cerrado城市化景观中的甲虫的分类学和功能多样性

城市化改变了自然生态系统,创造了一个环境马赛克,其特征是本地植被与人工建筑相混合。在这项研究中,我们比较了巴西Cerrado城市景观中住宅和绿地(原生植被的残留物)之间的粪甲虫分类和功能多样性。我们在2月(2013–2014 – 2015年)的巴西塞拉多(Cerado)遗迹(以下简称“绿地”)的四个残留地点和巴西南马托格罗索州阿基多纳(Aquidauana)的四个居住地点采样了甲虫。绿地的特征是混合了两种不同层的植物(植物生理学Cerrado sensustricto),树木茂密的树木和大灌木丛,而住宅区的特征是住宅建筑(房屋和商业用地),未铺设树木的道路街道。绿地中粪甲虫的丰度和物种丰富度较高。不同生境之间的物种组成差异很大,但功能组成没有差异。在绿地中,功能分散性和功能丰富性较高。另一方面,绿地和居民区之间的功能均匀性相似。在这项研究中,我们发现与巴西Cerrado的居民点相比,绿地中的粪甲虫多样性具有更高的分类学和功能成分。因此,我们强调了绿地对于保护甲虫生物多样性及其生态服务(例如土壤通气,二次种子扩散,寄生虫调节)的重要性,这些间接影响了城市居民的生活质量。
