Recent experiences on various points of the biology of clitellate works (oligochaetes and leeches) are present in the lawsuits of the newest foreign Symposium on Aquatic Oligochaete Biology - from improvement to inhabitants dynamics and from ultrastructure to evolution. nearly all of the contributions, that have a really extensive geographic scope, are investigations of the biology and ecology of oligochaete works in typical and polluted waters.

Regardless of being identified and studied for years, peptides have by no means sooner than attracted sufficient consciousness to necessitate the discovery of the time period "peptidomics" so as to specify the examine of the supplement of peptides from a cellphone, organelle, tissue or organism. In Peptidomics: equipment and Protocols, professional researchers current a finished variety of analytical strategies for the research of the peptide contents of advanced organic samples with an emphasis usually on greater throughput ideas, appropriate for the research of huge numbers of peptides often found in the peptidomes.

The truth that not one of the recognized DNA polymerases is ready to begin DNA chains yet in basic terms to lengthen from a unfastened three' -OH crew increases the matter of the way replication is initiated, either on the replication foundation and on Okazaki frag­ ments. It used to be first proven by means of A. KORNBERG et al. common mechanism to begin replication is thru the formation of an RNA primer catalyzed by way of RNA polymerases or through a brand new type of enzymes, the primases (KORNBERG 1980).

Reynoldson (eds), Aquatic Oligochaete Biology VI. © 1996 Kluwer Academic Publishers. 31 Species separation and identification in the Enchytraeidae (Oligo chaeta, Annelida): combining morphology with general protein data Rudiger M. Schmelz University of Osnabrock, FB 5, AG SpezieUe Zoologie D-49069 Osnabrock, Germany Key words: Enchytraeidae, Oligochaeta, taxonomy, general protein, morphology Abstract In the Enchytraeidae, species separation and identification is often problematic due to high morphological similarity of closely related species and considerable intraspecific variability of crucial characteristics.

This kind of sympatric distribution also raises questions about the evolutionary relationships of the co-occurring species - are they sister species or 28 distant relatives - and speciation modes. Co-occurring congeners include: Pristinella longidentata, Pristinella sp. 1 and Pristinella sp. 2; P. jenkinae and P. notopara; Pristina americana, Pristina sp. 1, P. aequiseta, P. biserrata, P. synclites, P. macrochaeta; and Dero indicus, Dero sp. 1, D. digitata and D. lodeni. These records also indicate that very careful taxonomic studies, including morphometry, are needed to show that the species indeed can be and are consistently distinguished.
