Blood-Clot

,Impact of prehistoric settlements on the Cladocera in the sediments of Lakes Suszek, Błȩdowo, and Sal. On the contrary, in the two remaining lakes, in which the human influence was more intense, the eutrophication process underwent intensive changes and coincided somewhat with settlement fluctuations.

Effect of food conditions on the bacterial feeding of ,,ange in the selectivity coefficient. A mechanism of ‘clogging’ suggestively explain the increase of bacterial ingestion efficiency by ., especially at high food concentrations. The change of selectivity coefficient related to food condition suggests that bacterial feeding by the . is incidental event associated with the algal feeding.

A review of the genus , (Crustacea: Anomopoda) from Europe,is not clear at this time. This paper gives information about European species, explains key characters in tabular form together with a pictorial key of European species. Also presented are common problems of working with . material, and a process of further study is explained.

A comparison of populations from the , group (Cladocera: Daphniidae),es of . The female has characteristic neonate, postabdomen, head, and ephippium. The male has characteristic rostrum, antennules, and the distalmost part of the postabdomen. The . group was compared with . s. str. Australian populations.

The late-glacial/holocene , (,) fauna of Lake Constance (Untersee) (F.R.G.): traces of introgressive Late-Glacial and the early Holocene the lake was inhabited only by . Leydig. In the Late Holocene a second species, . f. . Uljanin, appeared. In the uppermost sediment layers the morphological gap between the two taxa disappeared, apparently from introgressive hybridization.
