“…This effect cannot be explained by the weakening of intraspecific competition, as the correlation analysis showed. The initial population density of earthworms in all experimental variants was 159 individuals/m 2 , which is significantly lower than the density resulting in a decrease in the size and number of cocoons deposited [11,25,28]. For L. rubellus, it is 300 or more individuals/m 2 [11,25,28].…”

“…As a result of such a collision, native species can either be displaced or coexist [6][7][8][9]. Alien species of earthworms, once in the same habitat as the native ones, can have a variety of effects on each other: positive, neutral, or/and negative [10][11]. The more species involved in the interaction, the higher the number of negative effects [10].…”

Earthworm invasions often reduce biodiversity and affect the ability of ecosystems to perform ecosystem functions. Over the past few decades, European lumbricide species have spread widely in natural habitats in Western Siberia, without completely displacing the native species. The aim of the present experiment is to study the survival, reproductive potential, vertical distribution, abundance, and biomass of Aporrectodea caliginosa and Lumbricus rubellus invasive for the region and the native species Eisenia nordenskioldi and their influence on each other. For this purpose, winter and vegetation experiments were conducted in mesocosms simulating the real situation of invasions in the same communities on the same types of soils with the same amount and composition of litter. The authors found that the native species was significantly inferior to A. caliginosa in reproduction rate, number of offspring, and final biomass, but had an advantage over L. rubellus. The native species was positively influenced by the presence of A. caliginosa. In the experiment, there was a significant rejuvenation of the populations of the studied species, an increase in abundance and relative mass under interaction conditions compared to mono variants. The native species had advantages over the invasive species in terms of winter survival. The natural volume of litter used in the experiment was insufficient for L. rubellus. According to the results of the experiment, it can be assumed that the spread of L. rubellus will continue to be limited to non-freezing biotopes rich in organic matter. A. caliginosa will spread in natural communities and agrocenoses of Western Siberia.

“…Changes in earthworm community composition can impact many aspects of soils: the diversity and abundance of soil microbes (Eisenhauer et al 2007;Eisenhauer et al 2011;Uvarov et al 2019), carbon and nitrogen cycles (Hale et al 2005b;Huang 2015;Lubbers et al 2015), availability of macro-and micronutrients (Lavelle et al 2004, Bohlen et al 2004b, Hendrix et al 2006, Migge-Kleian et al 2006, рН (Hopfensperger et al 2011;Eisenhauer et al 2007), soil structure, and water characteristics (Coleman et al 2004;Hallam & Hodson 2020). Studying earthworm dispersal associated with the current climate changes is thus of interest not only to zoologists but also to ecologists.…”

Dispersal of earthworms from the Rudny Altai (Kazakhstan) into Western Siberia

et al. 2021

The aim of our study was to determine the current distribution, habitats, ecology, and possible dispersal routes of three species of the Rudny Altai (East Kazakhstan): Eisenia tracta, E. nana, and E. ventripapillata. We found that these species dispersed far beyond their original distribution into the flatland part of western Siberia (Russia) up to the central forest steppe of the Omsk oblast. E. tracta, E. nana, and E. ventripapillata were found in both floodplains and interfluvials. Hydrochory was the most plausible way of northward dispersal, while on interfluvials, they were probably introduced by humans. The studied species showed no preference for a particular habitat or river bank. The habitats were diverse and significantly different from the original ones in Rudny Altai. The factors that allowed E. tracta, E. nana, and E. ventripapillata to colonize western Siberia were probably their wide tolerance range to soil pH, temperature, density, and humidity, along with the decrease of winter soil freezing in recent decades. This is the first information about the occurrence of these species of earthworms in Siberia.
