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 water bodies over the period under consideration on the basis of the ...
The traces of Holocene events in the spore and pollen spectra of peat deposits in the southern part of the Kaliningrad Region
New data on the palaeoenvironment (vegetation and climate) in the southern part of the Kaliningrad Region were obtained through the processing of peat samples from Podlipovo peatland by means of pollen analysis. The results of the study indicate the prevalence of pine and birch forests in the early Holocene; the gradual introduction of broadleaved species occurred in the middle Holocene (the Atlantic). Fagus and Carpinus expansion in the sub-Boreal and sub-Atlantic affected the species composition of broadleaved forests; this period also saw the proliferation of broadleaved-coniferous forests. Pollen diagram was divided into 8 local pollen assemblage zones (LPAZ). The development of the bog was traced by means of peat macroremnants ...
The species diversity of zoobenthos, bioindication and the ecological condition of the Kaliningrad region lakes
This article offers the results of research on zoobenthos species composition in the Kaliningrad region. The authors estimate the ecological condition of lakes with the help of individual saprobity indices of bottom organisms.
