摘要
为了阐明蚂蚁巢穴对其他地表节肢动物群落组成和多样性的影响,于2019年在胜山自然保护区的原始阔叶红松林内开展实验,并采用陷阱法收集地表节肢动物。共捕获地表节肢动物92266只,分别为蜈蚣目、盲蛛目、马陆目、蜘蛛目,大头蚁属和步甲科、隐翅虫科、葬甲科这8个类群;蚂蚁巢穴存在及到蚂蚁巢穴的不同距离对其他地表节肢动物个体数量存在显著影响,其影响因类群而异。蚂蚁巢穴对蜈蚣和蜘蛛有促进作用,对盲蛛、马陆和步甲科类群有抑制作用,对葬甲科与隐翅虫科无显著影响;对照样地和距蚂蚁巢穴较远群落的Shannon指数、Pielou指数和Simpson指数更高;蚂蚁巢穴样地群落Beta多样性更高,且Beta多样性主要由空间物种转换组成,表明存在较高的空间物种替换,即蚂蚁巢穴导致群落类群组成较大的差异。本研究表明,蚂蚁巢穴存在和距离远近都是影响其他地表节肢动物群落多样性的因素。
An investigation was carried out in the primary broad-leaved Korean pine forest in Shengshan Nature Reserve in 2019 to clarify the impacts of ant nests on the composition and diversity of other ground-dwelling arthropods. The trap method was used to collect ants and other ground-dwelling arthropods. A total of 92266 ground-dwelling arthropods belonging to eight groups were captured, including Centipede, Arachnid, Malarcana, Arachnid, Macrocephalus, Carabidae, Paederanidae, and Silphidae. The presence of ant nests and the distance to ant nests significantly impacted the abundance of other ground-dwelling arthropods, with the impacts varying across groups. The presence of ant nests increased individual abundance of Centipede and Arachnid, decreased that of Arachnid, Malarcana and Carabidae, but did not affect Silphidae and Paederidae. The Shannon, Pielou and Simpson indices of other ground-dwelling arthropod communities were higher in the control plots and the communities far away from the ant nests. The beta diversity of the other ground-dwelling arthropod communities in plots having ant nests was higher, which mainly composed of spatial species turnover, indicating that there was higher spatial species replacement and that the presence of ant nests led to a larger difference of community composition. Our results indicate that the presence of ant nests and the distance to ant nests are important factors affecting the diversity of other ground-dwelling arthropod communities.
