Abstract

Red wood ants are keystone species in forest ecosystems. Because ants are active polyphagous predators, they control the abundance of other arthropods. In addition to direct effects on other species, there are a number of indirect effects caused by ants. In our study, we investigated the influence of ants on springtails, which they rarely come into contact with. Springtails have been set as a model group to assess the state of soil animals, since they are one of the most numerous and widespread groups of soil microarthropods. They are characterized by high sensitivity to environmental changes. The basic characteristics (abundance, species richness, and species diversity) of the springtail community and the response of certain species to the presence of ant trails have been studied. The total abundance and species richness of springtails decreased along ant trails. Among occurred species Parisotoma ParIsotoma notabilis, Lepidacyrtus lignorum, Isotomiella minor, Desoria tigrina, and Pseudasinella alba are the most numerous species both along ant trails and in control samples. There are no significant changes in species diversity (assessed by the Shannon-Weaver index). Species structure of springtail communities along ant trails and in control is different. Two groups of common Collembola species are identified: (1) increasing their numbers in the presence of ants, (2) on the contrary, decreasing. The presence of ants in a forest ecosystem influences the soil springtail community, although ant-Collembola interactions are indirect.

环节动物和蚂蚁红木蚁(Formica lugubris)的足迹对土壤中春蜱群落的影响
红木蚂蚁是森林生态系统中的关键物种。由于蚂蚁是活跃的多食性捕食者,它们控制着其他节肢动物的数量。除了对其他物种的直接影响外,蚂蚁还造成了许多间接影响。在我们的研究中,我们调查了蚂蚁对春蜱的影响,因为它们很少接触春蜱。由于春尾螨是数量最多、分布最广的土壤微节肢动物之一,因此被设定为评估土壤动物状况的模型类群。它们的特点是对环境变化高度敏感。我们对春尾动物群落的基本特征(丰度、物种丰富度和物种多样性)以及某些物种对蚂蚁足迹存在的反应进行了研究。蚁道沿线春尾的总丰度和物种丰富度都有所下降。在出现的物种中,Parisotoma ParIsotoma notabilis、Lepidacyrtus lignorum、Isotomiella minor、Desoria tigrina 和 Pseudasinella alba 是蚁道沿线和对照样本中数量最多的物种。物种多样性(以香农-韦弗指数评估)没有明显变化。蚁道沿线和对照样本中春尾虫群落的物种结构有所不同。发现两类常见的鞘翅目昆虫:(1) 在有蚂蚁的情况下数量增加,(2) 相反,数量减少。森林生态系统中蚂蚁的存在会影响土壤中的春尾虫群落,尽管蚂蚁与鞘翅目昆虫之间的相互作用是间接的。

期刊介绍: Pedobiologia publishes peer reviewed articles describing original work in the field of soil ecology, which includes the study of soil organisms and their interactions with factors in their biotic and abiotic environments. Analysis of biological structures, interactions, functions, and processes in soil is fundamental for understanding the dynamical nature of terrestrial ecosystems, a prerequisite for appropriate soil management. The scope of this journal consists of fundamental and applied aspects of soil ecology; key focal points include interactions among organisms in soil, organismal controls on soil processes, causes and consequences of soil biodiversity, and aboveground-belowground interactions. We publish: original research that tests clearly defined hypotheses addressing topics of current interest in soil ecology (including studies demonstrating nonsignificant effects); descriptions of novel methodological approaches, or evaluations of current approaches, that address a clear need in soil ecology research; innovative syntheses of the soil ecology literature, including metaanalyses, topical in depth reviews and short opinion/perspective pieces, and descriptions of original conceptual frameworks; and short notes reporting novel observations of ecological significance.
