Crop area (CA) and agricultural management intensity (AMI) are the two main factors associated with agricultural systems that can negatively affect the diversity of animal communities. Despite existing knowledge, the effect of both factors has not been analyzed for all biological groups. In this study, we evaluated the effect of CA and AMI in two types of crop farming (intensive and semitraditional) on the diversity of tropical lizards in a mosaic of agricultural land and subdeciduous tropical forest. The results of this study show that by grouping crops, CA reduces lizard species richness and diversity, while lizard abundance is not related to either CA or AMI. However, when crops are assessed separately, AMI and CA are found to reduce richness and diversity in semitraditional crops. Lizard abundances in both types of crops are unrelated to any factor. Our results show that lizard diversity is more affected by CA than AMI; however, the magnitude of the effect depends on the type of crop farming.

种植面积和管理强度如何影响热带蜥蜴物种多样性？

作物面积 (CA) 和农业管理强度 (AMI) 是与农业系统相关的两个主要因素，它们会对动物群落的多样性产生负面影响。尽管已有知识，但尚未对所有生物群体分析这两个因素的影响。在这项研究中，我们评估了 CA 和 AMI 在两种类型的作物种植（集约化和半传统化）中对农业用地和亚落叶热带森林马赛克中热带蜥蜴多样性的影响。这项研究的结果表明，通过对作物进行分组，CA 降低了蜥蜴物种的丰富度和多样性，而蜥蜴的丰度与 CA 或 AMI 无关。然而，当分别评估作物时，发现 AMI 和 CA 会降低半传统作物的丰富度和多样性。两种作物中蜥蜴的丰度与任何因素都无关。我们的结果表明，与 AMI 相比，CA 对蜥蜴多样性的影响更大；然而，影响的程度取决于作物种植的类型。
