Earthworms newly from Mongolia (Oligochaeta, Lumbricidae, Eisenia)
Two new megadrile earthworms from the steppes, the first species wholly from Outer Mongolia, are ascribed to the partially parthenogenetic Eisenia nordenskioldi (Eisen, 1879) species-complex. Taxonomic justification of sympatric Eisenia nordenskioldi mongol and Eisenia nordenskioldi onon ssp. n. are supported by mtDNA COI barcodes. The unreliability of molecular differentiation based on voucher...
متن کاملUniparental reproduction of Eisenia fetida and E. andrei (Oligochaeta: Lumbricidae): evidence of self- insemination
This study investigated the copulatory behaviour of the lumbricid earthworm Eisenia fetida (Savigny, 1826) in a natural population, and the uniparental reproduction of E. fetida and E. andrei Bouché 1972, two closely-related species. Sperm transfer occurred in 61 % of the matings observed, of which 88.2 % showed bi-directional sperm transfer, 9.8 % unidirectional sperm transfer and one earthwor...
متن کاملPolyploid races, genetic structure and morphological features of earthworm Aporrectodea rosea (Savigny, 1826) (Oligochaeta, Lumbricidae) in Ukraine
Four chromosomal races (2n=36, 3n=54, 6n=108, 8n=144) and 96 clones have been revealed among 224 specimens of the earthworm Aporrectodea rosea over the territory of Ukraine by means of karyological analysis and biochemical genetic marking. Each population has been showed by several clones at least; moreover the clones from different places have never been identical. The clones in the range of o...
متن کاملReview of the earthworm fauna of Iran with emphasis on Kohgiluyeh & Boyer-Ahmad Province.
Earthworms were collected in forests, damp habitats, springs, orchards and agricultural fields of the Kohgiluyeh & Boyer Ahmad Province, Iran, from April 2009 to April 2010. Specimens were collected at 20 established stations by digging and by diluted formalin methods. Ten species belonging to family Lumbricidae were identified based on morphology: Aporrectodea caliginosa (Savigny, 1826), Ap. r...
متن کاملSelf-Assemblage and Quorum in the Earthworm Eisenia fetida (Oligochaete, Lumbricidae)
Despite their ubiquity and ecological significance in temperate ecosystems, the behavioural ecology of earthworms is not well described. This study examines the mechanisms that govern aggregation behaviour specially the tendency of individuals to leave or join groups in the compost earthworm Eisenia fetida, a species with considerable economic importance, especially in waste management applicat...
