Sacred groves (SGs) of India are islets of forests providing ecosystem and spiritual services to man. Studies suggest that SGs are deteriorating on their quality due to urbanization, invasive species, land-use change, and religious modernization. We explored diversity, community, and abundance of overall and different functional groups of litter ants, including Anoplolepis gracilipes – an invasive ant – on paired SG-neighbouring home garden (HG) sites in rural and urban landscape to (a) assess the quality of SGs and (b) examine whether the variation in ant community of the two habitats was predicted by urbanization and abundance of A. gracilipes. We considered species and local contribution to β-diversity to identify species and sites crucial for conservation of sites. Abundance and richness of overall ants, proportional trap incidence of species, and abundance of A. gracilipes were similar on SG and HG, but species diversity and abundance of certain ant functional groups were higher on SG. Ant community of SG was different from HG, but was not affected by urbanization. A. gracilipes and rural SGs contributed the most to β diversity. A. gracilipes gave little pressure on native ant community. The study concludes that SGs, despite invaded by A. gracilipes, have potential for conserving biodiversity.

在城市化背景下,使用落叶蚂蚁作为指标,深入了解圣林(岛屿栖息地)的质量

印度的圣林 (SG) 是为人类提供生态系统和精神服务的森林小岛。研究表明,由于城市化、入侵物种、土地利用变化和宗教现代化,SG 的质量正在恶化。我们探索了垃圾蚂蚁的整体和不同功能组的多样性、社区和丰富性,包括细长按蚊- 入侵蚂蚁 - 在农村和城市景观中成对的 SG 邻居家庭花园 (HG) 站点上,以 (a) 评估 SG 的质量和 (b) 检查两个栖息地的蚂蚁群落变化是否可以通过城市化和丰富的A. 细细条. 我们考虑了物种和当地对β- 识别对遗址保护至关重要的物种和遗址的多样性。整体蚂蚁的丰度和丰富度,物种的比例陷阱发生率,以及蚂蚁的丰度A. 细细条在 SG 和 HG 上相似,但在 SG 上物种多样性和某些蚂蚁官能团的丰度更高。SG的蚂蚁群落与HG不同,但不受城市化的影响。A. 细细条农村地区的 SG 贡献最大β多样性。A. 细细条对原生蚂蚁社区几乎没有压力。该研究得出结论,尽管 SGs 受到了A. 细细条,具有保护生物多样性的潜力。
