Comparison of gastrotrich fauna on elodeids and in bottom sediments of lakes of different trophic status (the region Polesie Lubelskie, Eastern Poland)Abstract
Species diversity of gastrotrich communities on elodeids and in bottom sediments of lakes of different trophic status was compared. Thirty-eight species of Gastrotricha (34 in bottom sediment and 21 on elodeids) were found, which belong to the only family of Chaetonotidae Zelinka, 1889. Species diversity of both habitats was reflected in the... ... hiện toàn bộ

The first record of Piscicola pojmanskae Bielecki, 1994 in the Gulf of Gdańsk (the southern Baltic Sea) with species characteristics distinguishing it from Piscicola geometra (Linnaeus, 1758)
Oceanological and Hydrobiological Studies - Tập 43 - Trang 324-327 - 2014
Specimens of Piscicola pojmanskae were identified in the macrozoobenthos community in Zostera meadows in Puck Bay. The presented paper is the first report on the observation of this species in the Gulf of Gdańsk (the southern Baltic Sea). Leeches are a rare component of the benthic fauna in this brackish water area.
The story of one clam. Probably the oldest location of the Chinese pond mussel Sinanodonta woodiana (Lea, 1834) (Bivalvia, Unionidae) in Poland
Oceanological and Hydrobiological Studies - Tập 41 - Trang 41-45 - 2011
The discovery of a shell of the Chinese pond mussel in 1998 and further confirmation of this species indicate that a reservoir with natural thermal conditions is the oldest species location in Poland. Growth increments of an archival shell do not fall within the ranges obtained by this species in Konin lakes. They are, however, close to population ranges from Hungary. In contrast to other specimen...... hiện toàn bộ
New taxa of the genus Navicula (Bacillariophyceae) in the diatom flora of Serbia
Oceanological and Hydrobiological Studies - Tập 43 - Trang 185-190 - 2014
The main objective of this paper is to report two benthic, epilithic diatom species from the Raška River. Samples were collected in April, June, August and November 2011 and March and May 2012 from 5 localities along the Raška River by scraping off the stone surface using a brush. Diatom frustules were first cleaned using the cold acid method, and then mounted on permanent slides. Descriptions (ma...... hiện toàn bộ
Inventory of the taxonomical composition of the plankton ciliates in the Curonian Lagoon (SE Baltic Sea)
Oceanological and Hydrobiological Studies - Tập 40 - Trang 86-95 - 2011
Species composition of plankton ciliates was studied in the Curonian Lagoon in 2007–2008 and compared to long term investigations dating back to the 1980th. In total, 152 taxa were identified at the level of species or genera. More species (76 species/higher taxa) was found in the estuarine part of the Lagoon due to temporally unstable salinity and the presence of both freshwater and brackish/mari...... hiện toàn bộ
Spatial distribution of rotifers (Rotifera) in monospecies beds of invasive Vallisneria spiralis L. in heated lakes
Oceanological and Hydrobiological Studies - Tập 40 - Trang 71-76 - 2011
Species abundance and richness of rotifer communities occupying monospecies beds of Vallisneria was studied in Lake Licheńskie included in the open cooling system of heat and power stations. Differences were found in rotifer numbers, species composition and diversity between sampling points within the same location and between the locations. Factors that seem to be responsible for the high diversi...... hiện toàn bộ
Diatomological aspects of the Fenn’s and Whixall Mosses complex (Shropshire, UK)Abstract
Peat bogs are unique and important habitats for biodiversity at the species and ecosystem level where low pH of water plays a major role. The main objective of the present study was to compare the benthic diatom assemblage structure of the selected part of the Fenn’s and Whixall Mosses complex in order to verify whether selected sampling sit... ... hiện toàn bộ

Chlorophyll distribution by oceanic model and satellite data in the Bay of Bengal and Andaman Sea
Oceanological and Hydrobiological Studies - Tập 42 - Trang 132-138 - 2013
An oceanic model and satellite data are used to evaluate the seasonal distribution of chlorophyll-a (Chl-a) in the Bay of Bengal (BoB) and Andaman Sea. Satellite data show high Chl-a concentrations because high Chl-a concentrations reduce CO2 and increase O2 at the sea surface, indicating fish abundance in the ocean. Sample collection alone cannot provide an accurate overview of Chl-a concentratio...... hiện toàn bộ
Nematodes found in the European anchovy (Engraulis encrasicolus), a rare visitor to the Baltic Sea
Oceanological and Hydrobiological Studies - Tập 41 - Trang 99-102 - 2012
The European anchovy, Engraulis encrasicolus (Linnaeus, 1758), enters the Baltic Sea only occasionally. Little is known about the parasites that inhabit this fish in the northern part of its natural range (north-eastern Atlantic). This study is based on 32 anchovies sampled in autumn 2006 from a substantial bycatch accompanying sprat in the Gulf of Gdańsk (southern Baltic Sea). The fish were exami...... hiện toàn bộ
Tình trạng sinh thái của hồ Gorbacz cạn (Đông Bắc Ba Lan) trong giai đoạn cuối trước khi cạn kiệt Dịch bởi AI
Oceanological and Hydrobiological Studies - Tập 40 Số 2 - Trang 1-12 - 2011
Bài báo đánh giá tình trạng sinh thái của hồ Gorbacz cạn (Đông Bắc Ba Lan) trong giai đoạn cuối trước khi cạn kiệt hoàn toàn. Trong vài năm qua, chế độ thủy văn của lưu vực hồ đã thay đổi đáng kể do hoạt động của mỏ than bùn gần đó và các đợt hạn hán kéo dài vào mùa thu trong những năm tiếp theo. Sự phát triển của các loài thực vật nổi đã dẫn đến sự bao phủ hoàn toàn của các loài thực vật nổi kể t...... hiện toàn bộ
