The density of Oligochaetes
was observed to be highest at St I (153 ind.
Spot fed on polychaetes, other zooplankton, bivalves, oligochaetes
and fish during April (Fig.
1) Artificial diet with 45% Protein (LFd 1) (2) Rotifers like Asplanchna and Brachionus (LFd2) (3) Wild Zooplankton (LFd3) (4) Bioenriched zooplanktons (raised on Chlorella, cod liver oil and vitamin C) (LFd4) (5) Artemia (LFd5) (6) Chironomus (LFd6) (7) Oligochaetes
However, also the brackish-water oligochaete
Potamothrix bavaricus was repeatedly found here; the ostracod Cyprideis torosa and the calanoid Centropages sp.
The spermatozoon of Eudrilus eugeniae (Oligochaeta: Annelida): the first record of an endonuclear canal in Oligochaete
This result indicates that no-till systems are meeting the objective of reducing the amount of fine sediments entering streams, since oligochaete
worms and sphaeriid clams prefer conditions with large amounts of fine sediments (Thorpe and Covich, 2001).
Twenty-six species from various animal groups bear his name, including twelve spiders, four flies, a tardigrade and an oligochaete
Eighty percent of the species are insects, and the other 20% comprise spiders, scorpions and mites, nematode, oligochaete
and annelid worms, millipedes and centipedes, slugs, snails, freshwater bivalves, and crustaceans.
taxa were grouped, and voltinism was uncertain; thus production was estimated using a P/B value of 5.
This study is designed to understand the genetic architecture of resistance to metal in a metal-tolerant aquatic oligochaete
Benthic communities are usually dominated by different species of polychaete, oligochaete
worms, gastropods, bivalvia and various minor insect larvae.
assemblages in the hyporheic zone and coarse surface sediments: their importance for understanding of ecological functioning of watercourses.
