Long-term distribution of the crustacean Calanoida (Copepoda) in the dumping area in the South East Baltic
... part of the Baltic Sea. A hydrobiological study was carried out in spring and summer of 1998—2009 in the framework of national monitoring. The species composition of the Calanoida group was identified as well as the variations in their abundance and biomass. A seasonal (spring – summer) increase in the abundance and biomass of zooplankton and Calanoida was observed. The seasonal increase took place against the background of a steady decrease in the abundance abundance and biomass of crustacean ...
Molecular genetic identification of bacterial isolates — xylanase producers
... various industries, making the search for new microorganisms capable of producing these enzymes a highly relevant task. A source for isolating strains with xylanolytic activity is plant-based materials rich in hemicelluloses, such as lignocellulosic biomass. In the Kaliningrad region, such materials include the meal of industrial hemp seeds (Cannabis sativa), seed hulls and seeds of white lupine (Lupinus albus), unroasted soybean hulls, roasted soybean hulls, granulated soybean hulls, and seeds of ...
Character-istics of communities chironomids lakes of the city of Kaliningrad
This article investigates the state of chironomid communities in Lake Penkovoe, Pond Isakovsky, Pond Shkolny, and the Karasevka pond system in Kaliningrad in spring 2011. The authors provide new data on the species composition, abundance, and biomass of chironomidae. The Shannon, Simpson, Balushkin, and Margalef indices were calculated for the chironomid communities. The authors identified the dominant species in the communities of chironomids and evaluated the quality of water in the studied ...
