The data seem to confirm the typical demographic strategy of . i.e. high fecundity and high mortality in the early life stages. The total annual production of the species was estimated at 91.7 g (w.w.) m.. The low P/B ratio (2.0 yr.) is considered to be mainly due to high population densities.

Kapitel 7: Aufstand gegen den PEN-Club,consisted mostly of tolerant species (., and ., did not indicate an improvement of environmental conditions between 1980 and 1990. In Lake Joux the ratio of chironomid to oligochaete biomass was a more simple indicator of change than the species present in oligochaete communities.

, a new genus and species of Lumbriculidae (Clitellata) from a temporary pond in Alabama, USAthe atria. In partially mature forms, a rudimentary second pair of ovaries without female funnels was observed, which is not present in mature worms. Mature worms are found throughout the period when the temporary pond in which the taxon was found is full, suggesting that it is a hyporheic form.

Oligochaetes (Naididae, Tubificidae, Opistocystidae, Enchytraeidae, Sparganophilidae and Alluroidida. and ., especially considering the small number of locations that have been sampled. The collections include approximately 12 new species of rhyacodrilines (Tubificidae), . (Naididae), . (Alluroididae), . and . (Enchytraeidae). This is the first record of . from outside of Africa and the first new record since 1952.

International Symposium on Aquatic Oligochaete Biology- from development to population dynamics and fromultrastructure to evolution. The majority of the contributions, whichhave a very broad geographic scope, are investigations of the biologyand ecology of oligochaete works in natural and polluted

The effect of water movement on the distribution of Oligochaeta in lakesf‘ sapropel’, can also be limiting to the distribution of oligochaetes. Organic contamination in conditions of low water dynamics can result in the absence of Oligochaeta through oxygen depletion. Dynamic water movement can stimulate the mass development of Oligochaeta in organically polluted areas.
