Abstract

We aimed to assess how bats are affected by habitat transformation by comparing bat assemblages in four habitat types: primary forest, secondary forest, cocoa plantations and human habitations in the Dja Biosphere Reserve of southern Cameroon. Bats were sampled in the four habitat types using mist nets. During 126 nights, a total of 413 bats were captured, belonging to four families, 16 genera and 24 species. Ninety three individuals (17 species) were captured in the primary forest, followed by plantations (105 individuals, 14 species), human habitations (159 individuals, 10 species), and secondary forest (55 individuals, eight species). Megaloglossus woermanni was recorded in all the four habitats, and was the most abundant species (105 individuals). The analysis of bat assemblage between habitat types showed a statistically significant difference in species composition. The distribution of the six most abundant species (Epomops franqueti, Megaloglossus woermanni, Rousettus aegyptiacus, Dohyrina cyclops, Hipposideros cf. caffer and Hipposideros cf. ruber) was influenced by habitat types. Our results suggest that the decrease in species richness observed in disturbed habitats may be due to habitat perturbations of primary forest habitats. Therefore, it is important to examine the effects of habitat conversion at species level, as responses are often species-specific.

喀麦隆南部蝙蝠群落(哺乳目:翼翅目)对森林消失和栖息地转换的响应
通过比较喀麦隆南部Dja生物圈保护区四种生境类型(原生林、次生林、可可种植园和人类生境)中的蝙蝠种群,研究了生境变化对蝙蝠种群的影响。使用雾网对四种生境类型的蝙蝠进行取样。在126个夜晚,共捕获蝙蝠413只,隶属4科16属24种。在原生林中捕获93只(17种),其次是人工林(105只,14种)、人类生境(159只,10种)和次生林(55只,8种)。在4个生境中均有记录,数量最多(105只)。不同生境类型间的蝙蝠种群组成差异有统计学意义。最丰富的6个物种(franqueti epoomops、Megaloglossus woermanni、Rousettus aegyptiacus、Dohyrina cyclops、Hipposideros cf. caffer和Hipposideros cf. ruber)的分布受生境类型的影响。研究结果表明,受干扰生境中物种丰富度的下降可能是由于原始森林生境的扰动所致。因此,在物种水平上研究生境转换的影响是很重要的,因为反应往往是物种特有的。
