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.
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.
