啮齿动物群落在生态系统功能和保护区管理中具有重要的生态学意义。本研究考察了稀树草原环境中四种生境类型（即Miombo林地、金合欢林地、草原和农田）中啮齿动物的组合模式。捕获-标记-再捕获（CMR）方法应用于整个Chembe鸟类保护区（CBS）景观的数据收集。采用非度量多维尺度（NMDS）进行探索性数据分析，然后进行方差分析（ANOVA）和Tukey-Kramer 's诚实显著性差异（HSD）事后检验。非农田（Miombo林地、金合欢林地和草地）与农田的鼠类组合存在显著差异。(1)农田鼠类多样性为零，主要以一种有害动物natalensis为主；(2) 3种非农田生境类型鼠类组合的差异。我们建议通过保护规划和保护区边界之外的多方利益相关者合作来调节啮齿动物的组合，以积极促进CBS景观的工作。
Rodent assemblages have ecological importance in ecosystem functioning and protected area management. Our study examines the patterns of assemblages of rodents across four habitat types (i.e., Miombo woodland, Acacia woodland, grasslands and farmlands) in the savanna environment. Capture-mark-recapture (CMR) methods were applied for data collection across the Chembe Bird Sanctuary (CBS) landscape. The Non-metric Multi-Dimensional Scaling (NMDS) was used for exploratory data analysis, followed by Analysis of Variance (ANOVA) and Tukey–Kramer’s Honestly Significant Difference (HSD) post-hoc tests. The rodent assemblages in CBS significantly differed between the non-farmlands (i.e., Miombo woodland, Acacia woodland and grasslands) and farmlands. There were: (1) zero rodent diversity in farmlands, dominated completely by a pest species, M. natalensis; and (2) different rodent assemblages in three non-farmland habitat types. We suggest that rodent assemblages should be mediated by conservation planning and multi-stakeholder collaboration beyond the protected area boundaries to contribute to a working CBS landscape positively.
