Abstract Identifying the impact of agricultural management on soil invertebrates is still a challenge to research in the area of soil ecology. The aim of this study was to evaluate the diversity, richness, abundance and uniformity of the pedofauna in areas of traditional agroforestry systems involving burning (with intensive use, and after six and nine years of fallow) and a less-impacted system (BUSH) in the semi-arid region of Brazil. To do this, pitfall traps were installed along five transects in each system, and pedofauna diversity was analysed over seven consecutive days in the dry and rainy seasons. The collected invertebrates were classified into taxonomic groups, and their diversity, richness, abundance and uniformity were studied. During the dry season, the agroforestry systems showed low pedofauna diversity and uniformity, but with a richness similar to that of the BUSH system, whereas the traditional systems with fallow periods of six and nine years presented high diversity and uniformity. During the rainy season, the agroforestry systems had similar pedofauna abundance and richness compared to the BUSH system. The traditional fallow systems showed an abundance, richness, diversity and uniformity similar to the results under the BUSH system. Compared to the other areas, the traditional systems showed the greatest abundance and a similar richness, but less diversity and uniformity. When water is available, agroforestry systems support a diversity and uniformity of pedofauna similar to the less-impacted system.

巴西半干旱地区传统和农林业系统中的土壤动物多样性

摘要 确定农业管理对土壤无脊椎动物的影响仍然是土壤生态学领域研究的一个挑战。本研究的目的是评估涉及燃烧（大量使用，并在休耕 6 年和 9 年之后）和受影响较小的系统 (BUSH) 的传统农林复合系统区域中土壤动物群的多样性、丰富度、丰度和均匀性在巴西的半干旱地区。为此，在每个系统的五个样带上安装了陷阱陷阱，并在旱季和雨季连续 7 天分析了土壤动物群的多样性。将收集到的无脊椎动物分为分类群，并研究了它们的多样性、丰富度、丰度和均匀性。在旱季，农林业系统表现出低的土壤动物多样性和均匀性，但其丰富度与 BUSH 系统相似，而传统的休耕期为 6 年和 9 年的系统呈现出高度的多样性和统一性。在雨季，与 BUSH 系统相比，农林业系统具有相似的土壤动物丰度和丰富度。传统的休耕系统表现出与BUSH系统下的结果相似的丰富度、丰富度、多样性和均匀性。与其他地区相比，传统系统显示出最大的丰度和相似的丰富度，但多样性和均匀性较差。当水可用时，农林业系统支持与受影响较小的系统类似的土壤动物群的多样性和统一性。在雨季，与 BUSH 系统相比，农林业系统具有相似的土壤动物丰度和丰富度。传统的休耕系统表现出与BUSH系统下的结果相似的丰富度、丰富度、多样性和均匀性。与其他地区相比，传统系统显示出最大的丰度和相似的丰富度，但多样性和均匀性较差。当水可用时，农林业系统支持与受影响较小的系统类似的土壤动物群的多样性和统一性。在雨季，与 BUSH 系统相比，农林业系统具有相似的土壤动物丰度和丰富度。传统的休耕系统表现出与BUSH系统下的结果相似的丰富度、丰富度、多样性和均匀性。与其他地区相比，传统系统显示出最大的丰度和相似的丰富度，但多样性和均匀性较差。当水可用时，农林业系统支持与受影响较小的系统类似的土壤动物群的多样性和统一性。传统系统显示出最大的丰富度和相似的丰富度，但多样性和统一性较差。当水可用时，农林业系统支持与受影响较小的系统类似的土壤动物群的多样性和统一性。传统系统显示出最大的丰富度和相似的丰富度，但多样性和统一性较差。当水可用时，农林业系统支持与受影响较小的系统类似的土壤动物群的多样性和统一性。
