Par contre, les agriculteurs étaient intéressés à la technologie du vermicompostage et son utilisation, à conditions d'obtenir de meilleurs rendements et que la pratique soit disponible et abordable. Prior to the advent of useable systematic keys, little attempt was made to identify Great Lakes oligochaete species. Phylogenetic analysis of the aquatic Oligochaeta under the principle of parsimony. A preliminary review of the taxonomic characters used for the systematics of the genus Trichodrilus Clalarede Oligochaeta, Lumbriculidae. La faune aquatique souterraine et marine interesse particulierement les auteurs car elle n'a pas ete beaucoup etudiee.

Ces deux bases se sont revelees pertinentes et ont donne de bons resultats. Small earthworms belong to the Enchytraeidae, Tubificidae and Naididae families and are typically aquatic Rombke, 2003. Leeches, branchiobdellids, and lumbriculids form three independent parallel branches of evolution. New methods, including molecular studies, and renewed interest in ontogeny and detailed anatomical studies, may improve our ability to resolve clusters of taxa with few, if any, apomorphic character states that remain at the base of cladograms. The five anteriormost segments, each with four pairs of hookshaped chaetae arranged around the mouth opening, are considered to be functionally equivalent to an anterior sucker.

This chapter focuses on freshwater annelids of North America. Control of worm populations might be achieved by reducing organic inputs, lowering erosion, increasing flow and removing objects that accumulate pockets of silt. Its recognition is a continuing source of confusion to taxonomic resolution of Enchytraeidae. The Megascolecoidea, contains the Megascolecidae, Eudrilidae and Ocnerodrilidae, although the phylogram indicates that the Ocnerodrilidae should be placed in a separate and primitive superfamily of the Lumbricina. Ohfiochoeko in «ubkerroneon environmenk ond iiew descriptions : resells «in«abslrecl Oligochaetes are annelids wich are living in terrestrial, aquatic or subterranean environment. Three orders are recognized: the Lumbriculida and Tubificida, which were not computed and the affinities of which require further investigation and the Haplotaxida, computed.

As a rule, molecular trees are closely aligned with morphology-based phylogenies. The lumbriculids and branchiobdellidans may well be combined into a single taxon defined by their unique semi-prosopore male ducts, with lumbriculids defined by their unique muscle structure and the branchiobdellids by many apomorphic characters related to ectocommensal life. Tubificidae ainsi que la comparaison de la nouvelle espece a d'autres especes de Limnodrilus de Chine et a Limnodrilus silvani de Californie et d'oregon, Etats-Unis. The number of 29 true segments is concluded from the number of segmental ganglia. While both involve cladistic analyses, the differences focus on questions of homology. Six especes connues partout en Europe n'ont pas ete retrouvees en Italie sans doute par manque d'etude des eaux souterraines. Powerful tests of adaptational hypotheses can be made in the context of well-supported cladograms by investigating the most parsimonious transformation of intrinsic or extrinsic factors to explain their distribution across taxa in a cladogram.

A new species of Phallodrilus Oligochaeta : Tubificidae from a limestone cave in Bermuda. Propappidae and aquatic Enchytraeidae Oligochaeta from the farthest southeast of Russia. The earthworm Eudrilus eugeniae Kinberg , was found in the soil-litter layer at seven locations across Accra. Genre Stephensoniana Cemosvitov, 1938 Stephensoniana trivandrana Aiyer, 1926. The classificatory changes necessary to adjust these findings to the Hennigian dogma of monophyly, dominant for over 30 years now, lead to an increasingly cumbersome and unpractical system.

This difference was largely explained by the large difference in assimilation efficiency between cadmium and zinc. Swimming also occurred in amputated anterior and posterior body fragments.

The body apparently possesses neither a prostomium nor an achaetous buccal region peristomium. Atilodrihspigueti Kowalewski, 1914, Aulodrilus remex Stephenson, 1921 Aulodrilus prothecatus chen, 1940 sont des synonymes. Quoique la technique soit économique et produise un engrais organique ainsi que de la biomasse de vers, elle est rarement utilisée dans les régions au Sud du désert Sahara, en Afrique. Using the pharmacokinetic modeling approach and taking into account the distribution of the metal between water and sediment, the different routes were quantitatively separated.

En ce qui concerne les Tubiticidae en Italie, les especes strictement stygobiontes Haber zavreli, Frearidrilus pescei, Abyssidrilus cuspis illustrent 1'endemisme frequent ou au moins la distribution discontinue de la faune souterraine. A faunistic, distributional, and ecological synthesis of the world fauna inhabiting subterranean waters. In general, the results confirm Livanow's classic monograph 1906 , with the exception of a few details. A new American Stylodrilus species Lumbriculidae, Oligochaeta. Freshwater annelids oligochaetes, branchiobdellidans, leeches, and acanthobdellids can be found in both standing and flowing water and are often an important component of the aquatic food web. In recently collected specimens of Acanthobdella peledina the nervous system, the genital organs and the coelomic organisation were reinvestigated after complete serial sections. Более того, полиморфная группа байкальских люмбрикулид кластеризуется отдельно от других представителей семейства, что свидетельствует об уникальности байкальской фауны олигохет, сформировавшейся в относительно замкнутой системе этого древнего озера.
