Abstract

Reduced biodiversity and high number of endemics characterize island ecosystems. Island natives and endemics are considered more vulnerable than continental species to exotic species invasions and habitat changes. The effect of replacing a native forest by an exotic wood plantation was studied on the assemblage of native and endemic ant species. The main hypothesis was that endemic and native ant species were more vulnerable to habitat changes than the exotic ant species. Nevertheless, it was found that native ants were more numerous and specious in both native and exotic plantations. Also, high numbers of two endemic ants were detected within exotic plantations, while only one exotic ant Hypoponera opacipeps was relatively abundant, particularly on native forest. In conclusion, exotic ant species did not dominate the communities studied nor the native and endemic ant assemblages seemed to be affected negatively by the forest replacement.

大安的列斯群岛波多黎各岛落叶蚁易受森林干扰
生物多样性减少和大量地方性疾病是岛屿生态系统的特征。与大陆物种相比,岛屿原生物种和特有物种被认为更容易受到外来物种入侵和栖息地变化的影响。研究了外来人工林替代原生林对本地和特有蚁群的影响。主要假设是,特有和本地蚂蚁物种比外来蚂蚁物种更容易受到栖息地变化的影响。然而,我们发现在本地和外来人工林中,本地蚂蚁的数量和数量都更多。此外,在外来人工林中发现了大量的两种特有蚂蚁,而只有一种外来蚂蚁(Hypoponera opacipeps)相对丰富,特别是在原生森林中。综上所述,外来蚁种不占研究群落的主导地位,本地和特有蚁群也不受森林替代的负面影响。
