“…Even though differences in cold tolerance do limit the distributions of earthworm species at larger scales (Meshcheryakova et al 2014), the extent our study area, confined to the central lowlands of the western Kenai Peninsula, did not cover enough of a climatic gradient for consideration of temperature as a determinant of earthworm invasion success.…”

“…However, some of the more cold-hardy species present in the far north of the Palearctic, including D. octaedra and Dd. rubidus, may be able to survive in Interior Alaska based on the physiological and distributional data presented by Meshcheryakova et al (2014).…”

“…Of these, 14 are exotic worms introduced from the Palearctic and have become established. Eisenia fetida (Savigny, 1826), a Palearctic species, is commonly used for indoor vermicomposting in Alaska, but due to its low cold tolerance (Greiner et al 2011, Meshcheryakova andBerman 2014), it is unlikely to become established in Alaska. Two species of earthworms found in southeast Alaska (Arctiostrotus sp.…”

“…Survival of earthworms in low temperature areas depends on the species and stage of development (Greiner et al 2011, Meshcheryakova et al 2014). Meshcheryakova and Berman (2014), by comparing cold hardiness and present distributions of earthworm species in Siberia, concluded that varying cold tolerance of the species considered contributed toward their present distribution ranges.…”

Little is known about exotic earthworms (Oligochaeta: Lumbricidae) in Alaska outside its southeastern panhandle. This study documents the distribution of exotic earthworms in the relatively undisturbed Kenai National Wildlife Refuge (KNWR), a large, primarily wilderness refuge in southcentral Alaska. We sampled 69 sites near boat launches, along road corridors, and in low human impact areas > 5 km from the road, finding three species of earthworms (Dendrobaena octaedra, Dendrodrilus rubidus, and Lumbricus terrestris). Most road sites (90%) and boat launches (80%) contained earthworms; half (50%) of low human impact sites contained earthworms. Distance to roads was the only significant factor in predicting earthworm occurrence; soil pH, soil moisture, leaf litter depth, and vegetation cover were not. The disparate distributions of these three species suggest that within the KNWR road construction and vehicle traffic played a role in dispersal of the widespread, abundant Dendrobaena octaedra and uncommon Dendrodrilus rubidus; bait abandonment appeared to be the primary method of introduction of Lumbricus terrestris. While the distribution of harmful anecic earthworms in KNWR is currently limited, the prohibition of Lumbricus spp. as bait within conservation units in Alaska may be warranted.

“…Cold tolerance is another important factor: all invasive earthworms reported from Kamchatka are believed to have originated in warmer climates; however, they were nevertheless able to successfully colonize this peninsula that has rather harsh climate. Some of them (Dendrobaena octaedra, A. caliginosa, and both subspecies of E. nordenskioldi) are indeed characterized by high cold tolerance both as adult worms and cocoons (Berman et al 2002;Berman and Meshcheryakova 2013;Meshcheryakova and Berman 2014). However, other species (Dendrodrilus rubidus tenuis and L. rubellus) are cold tolerant only at the cocoon stage, while adult worms die at −1°C to −3°C (Berman et al 2010;Meshcheryakova and Berman 2014).…”

Invasive lumbricid earthworms of Kamchatka (Oligochaeta)

Background: Invasive earthworms often have huge ecological impact, especially when they colonize previously earthworm-free zones. Kamchatka is a remote and weakly populated region whose invertebrate fauna is insufficiently studied. We investigated earthworm diversity in several natural and anthropogenic habitats of Kamchatka by morphological analysis and barcoding using the mitochondrial cox1 gene. Results: We added four new species (Dendrobaena octaedra, Dendrobaena attemsi, Lumbricus rubellus, and Aporrectodea caliginosa) and one subspecies (Dendrodrilus rubidus subrubicundus) to the four earthworm species known previously from this region. Moreover, this is the first report of Dendrobaena attemsi in Asia. We found one mtDNA haplotype for each Eisenia fetida, Dendrodrilus rubidus subrubicundus, and Dendrodrilus rubidus tenuis; two significantly diverged haplotypes for Dendrobaena octaedra and A. caliginosa; and three for L. rubellus. In addition, cox1 sequences of Eisenia nordenskioldi nordenskioldi, the only earthworm species that could be of native origin, were identical to those of Eisenia nordenskioldi pallida from Khakassia and Tuva.Conclusions: Molecular genetic analysis demonstrated that all earthworms found by us are of invasive origin, and for some of them, there were most probably several independent introduction events. This turned out to be true even for E. nordenskioldi, the species that was earlier considered to be native to this region. Our results suggest it might be possible that the whole earthworm fauna of Kamchatka is of invasive origin, which makes it a good model for studying the effects of earthworm invasions into previously earthworm-free regions.
