“…Similar factors also drove the pattern of abundance‐based enchytraeid beta diversity in our study. Due to a series of environmental changes (e.g., temperature, soil moisture, litter depth) from the foot to summit of the Changbai Mountain, the community composition of Enchytraeidae was quite different among five typical forest types (Lian et al, ), for example, one of the dominant genera, Bryodrilus , mainly occurred in spruce–fir forest; Fridericia peaked in hardwood forest; and Mesenchytraeus was frequently found in high‐altitude environment with low temperature and rich organic matter. Furthermore, the pristine environment and suitable environmental conditions (e.g., abundant litter and organic matter) provide growth and reproduction advantages for these soil annelids, resulting in low differences in richness and abundance between sites at different elevations, that is, the low value of d BC‐gra .…”

“…Temperature, litter depth, and organic nitrogen were determined as important predictors of beta diversity of soil enchytraeids. These variables have been identified as significant correlates to soil potworm assemblages worldwide (Briones et al, ; Cole et al, ) and in the Changbai Mountain in particular (Lian et al, ). Thermal regime, food resources, and habitat conditions can affect the distributions of enchytraeid species with different environmental preferences and physiological tolerances.…”

“…Thermal regime, food resources, and habitat conditions can affect the distributions of enchytraeid species with different environmental preferences and physiological tolerances. For example, most species of Mesenchytraeus and Chamaedrilus (the original genus Cognettia in Lian et al, ) found on the Changbai Mountain typically occur in low‐temperature (high altitude or latitude region), permanently humid habitats rich in organic matter, whereas some thermophilous taxa (such as Fridericia unisetosa , Enchytraeus athecatus , Hemifridericia parva, and Hemienchytraeus stephensoni ) mainly present in regions with high soil temperature, and relatively low levels of moisture and litter. The key effects of these variables on enchytraeid distributions are pertaining to the environmental filtering perspective of metacommunity theory (Leibold et al, ).…”

The elevational alpha biodiversity gradient in mountain regions is one of the well‐known ecological patterns, but its beta diversity pattern remains poorly known. Examining the beta diversity and its components could enhance the understanding of community assembly mechanism. We studied the beta diversity pattern of the soil enchytraeids along a distinct elevational gradient (705–2,280 m) on the Changbai Mountain, the best‐preserved mountain in northeastern China. The overall abundance‐based community dissimilarity was relatively high (ca. 0.70), largely due to the balanced‐variation component (85%). The overall dissimilarity and its balanced‐variation (substitution) component were related to both local environmental heterogeneity and elevational distance, with the environmental relationships being stronger. In contrast, the abundance‐gradient (subsets) component was not related to the two gradients. The same important spatial and environmental variables were detected in structuring overall dissimilarity and substitution component, different from that in subsets component. Variation partitioning analysis showed that environmental control played a more important role than spatial (vertical and horizontal) factors in structuring the patterns of overall beta diversity and its two components. The predictive power of multivariate analysis was higher for the substitution component (nearly 50%) and overall dissimilarity (35%), but much lower for subsets components (<4%). These findings implied that abundance‐based beta diversity patterns of the soil enchytraeids were the results of different ecological processes (e.g., environmental sorting and dispersal limitation), operating in the two antithetic components. Our study showed the substitution and loss of individuals reflecting different ecological processes and highlights the importance of partitioning beta diversity in assessing biodiversity patterns and their causes.

“…Likewise, we have only hints of the probably high endemicity and diversity of tropical and temperate Africa, as well as of southern and eastern Asia and Australasia, and recent surveys in China (refs. in Wang and Cui 2007, Lian et al 2011) and Korea (Dózsa-Farkas and Hong 2010, Christensen and Dózsa-Farkas 2012, Dózsa-Farkas et al 2015) point to complex biogeographical relationships among the major world regions. The geographical sampling bias is only one of the reasons for the incompleteness of the global inventory.…”

Fauna Europaea provides a public web-service with an index of scientific names (including important synonyms) of all living European land and freshwater animals, their geographical distribution at country level (up to the Urals, excluding the Caucasus region), and some additional information. The Fauna Europaea project covers about 230,000 taxonomic names, including 130,000 accepted species and 14,000 accepted subspecies, which is much more than the originally projected number of 100,000 species. This represents a huge effort by more than 400 contributing specialists throughout Europe and is a unique (standard) reference suitable for many users in science, government, industry, nature conservation and education.This paper provides updated information on the taxonomic composition and distribution of the Annelida - terrestrial Oligochaeta (Megadrili and Enchytraeidae), Aphanoneura and Polychaeta, recorded in Europe. Data on 18 families, 11 autochthonous and 7 allochthonous, represented in our continent by a total of 800 species, are reviewed, beginning from their distinctness, phylogenetic status, diversity and global distribution, and following with major recent developments in taxonomic and faunistic research in Europe. A rich list of relevant references is appended. The Fauna Europaea Annelida - terrestrial Oligochaeta data-set, as completed in 2004, will be updated accordingly.

Abstract.-A new enchytraeid species, Mesenchytraeus asymmetriauritus sp. nov., collected from terrestrial habitats of Changbai Mountain in the northeast China, is described. It is characterized by the dorsal vessel originating in XV-XVII, four pairs of preclitellar nephridia in 6/7-9/10, spermathecae attached to oesophagus in segment V and each possessing three or four ear-shaped diverticula of different size, one pair of asymmetrical sperm sacs occupying X-XVII and containing bulk of naked sperm bundles, atrium cylindrical with 4 prostate-like glands and distinct from vas deferens, and well-developed egg sac extending to XVI-XVII.
