摘要

新热带森林生态系统拥有重要的生物多样性。要制定有效的昆虫保护措施,就必须了解影响物种多样性和种群结构的因素。白蚁的扩散是种群结构的一个关键决定因素,对在木材中筑巢的白蚁或生活在城市环境中的白蚁的扩散研究较多,因为扩散可能受到木材运输的影响。然而,对于流动性不受木材运输影响的白蚁的扩散,研究仍然不足。我们研究了Embiratermes neotenicus的扩散情况,它是一种以土壤为食的白蚁,扩散距离很短,在新热带地区,既有完整的森林,也有退化的森林。利用线粒体和核数据,我们对苏里南和法属圭亚那 70 个群落的遗传多样性、结构和导致种群分化的因素进行了多尺度分析。法属圭亚那的种群是该地区的祖先种群,后来扩大了。在苏里南和法属圭亚那观察到了种群间的显著遗传分化,并发现了不同的模式。苏里南种群显示出较高的遗传多样性,没有亚种群分化,而法属圭亚那种群则显示出不同遗传群的亚结构。对所有群落规模的分析表明,景观特征(如马罗尼河)对遗传分化有影响。在局部范围内,随着森林的改变,即使森林覆盖率没有发生重大变化,群落间的遗传分化也会增加。我们的研究结果凸显了土食白蚁种群对栖息地变化的敏感性。我们认为,需要进行多尺度研究,以全面了解遗传模式,特别是对于散布距离较短的物种。

The role of changing landscape in the dispersal of a soil‐feeding termite in Suriname and French Guiana
Neotropical forest ecosystems harbour significant biodiversity. To develop effective insect conservation practices, it is important to understand the factors that influence the diversity and population structure of the species. Dispersal, a key determinant of population structure, is well studied in termites nesting in wood, for which it can be influenced by wood transport, or in termites living in urban environments. However, understanding the dispersal of termites whose mobility remains unaffected by wood transport remains understudied. We investigated the dispersal of Embiratermes neotenicus, a soil‐feeding species with short dispersal distance, in the Neotropical region, where both intact and degraded forests exist. Using mitochondrial and nuclear data, we analysed genetic diversity, structure and factors contributing to population differentiation in Suriname and French Guiana at multiple scales for 70 colonies. The population in French Guiana is the ancestral population in the region that subsequently expanded. Significant genetic differentiation between populations was observed, with distinct patterns identified in Suriname and French Guiana. The Suriname population showed higher genetic diversity and no subpopulation differentiation, whereas the French Guiana population showed substructure into distinct genetic clusters. Analyses at the scale of all colonies suggest the influence of landscape features, such as the Maroni River, on genetic differentiation. At the local scale, genetic differentiation between colonies increases with forest alteration, even when this does not include major changes in forest cover. Our results highlight the sensitivity of soil‐feeding termite populations to habitat change. We argue that multi‐scale studies are needed for a comprehensive understanding of genetic patterns, especially for species with short dispersal distances.
