Introduced earthworm species exhibited unique patterns of seasonal activity and vertical distribution, and Lumbricus terrestris burrows remained usable for at least 7 years in hardwood and pine stands

This paper contains the results of qualitative analysis of Lumbricidae (Oligochaeta) in Montenegro, during the period 1997-2003. The research has included natural and cultivated biotopes. The presence of 15 species was established and the habitats, localities and their zoogeographical position are given. In Montenegro we found four species for the first time Dendrobaena jastrebensis, D. vejdovskyi, Octodrilus bretcheri and Lumbricus terrestris. The complete list of earthworm species in Montenegro includes 45 taxa. With respects to the zoogeographic situation of the earthworms in Montenegro, the largest number belongs to endemic (10) and European (10) species. But 8 taxa are south-European, 9 Holarctic, 7 cosmopolitan, and 1 Palearctic. The degree of endemism of the earthworm fauna of Montenegro is quite high, exceeding 22.2%.

ABSTRACT The guts and casts of earthworms contain microbial assemblages that process large amounts of organic polymeric substrates from plant litter and soil; however, the enzymatic potential of these microbial communities remains largely unexplored. In the present work, we retrieved carbohydrate-modifying enzymes through the activity screening of metagenomic fosmid libraries from cellulose-depleting microbial communities established with the fresh casts of two earthworm species, Aporrectodea caliginosa and Lumbricus terrestris, as inocula. Eight glycosyl hydrolases (GHs) from the A. caliginosa-derived community were multidomain endo-β-glucanases, β-glucosidases, β-cellobiohydrolases, β-galactosidase, and β-xylosidases of known GH families. In contrast, two GHs derived from the L. terrestris microbiome had no similarity to any known GHs and represented two novel families of β-galactosidases/α-arabinopyranosidases. Members of these families were annotated in public databases as conserved hypothetical proteins, with one being structurally related to isomerases/dehydratases. This study provides insight into their biochemistry, domain structures, and active-site architecture. The two communities were similar in bacterial composition but significantly different with regard to their eukaryotic inhabitants. Further sequence analysis of fosmids and plasmids bearing the GH-encoding genes, along with oligonucleotide usage pattern analysis, suggested that those apparently originated from Gammaproteobacteria (pseudomonads and Cellvibrio-like organisms), Betaproteobacteria (Comamonadaceae), and Alphaproteobacteria (Rhizobiales).
