Photosynthetic efficiency of endosymbiotic algae of Paramecium bursaria originating from locations with cold and warm climates

7 czerwca 2018 Grzegorz Kozlowski 0

Paramecium bursaria (Ciliophora) is a cosmopolitan unicellular organism that plays a significant role in aquatic ecosystems. P. bursaria contains symbiotic algae and this association is a mutual symbiosis. The aim of the present study was […]

First record of Sigara assimilis (Fieber, 1848) (Hemiptera: Heteroptera: Corixidae) in Poland

7 czerwca 2018 Grzegorz Kozlowski 0

Sigara assimilis (Fieber, 1848) is an aquatic true bug from the family Corixidae. Our paper is the first report on this species from Poland. Numerous males and females of the species were found in a […]

Spatial variability of long-term trends in significant wave height over the Gulf of Gdańsk using System Identification techniques

7 czerwca 2018 Grzegorz Kozlowski 0

The significant wave height field over the Gulf of Gdańsk in the Baltic Sea is simulated back to the late 19th century using selected data-driven System Identification techniques (Takagi-Sugeno-Kang neuro-fuzzy system and non-linear optimization methods) […]

Reproduction of Potamothrix hammoniensis (Oligochaeta) in shallow eutrophic lakes

7 czerwca 2018 Grzegorz Kozlowski 0

The aim of the study was to indicate the abiotic parameters of water and bottom sediments, which significantly affect the reproduction of Potamothrix hammoniensis in 9 shallow eutrophic lakes, of which 5 were dominated by […]

Diatom record of progressive anthropopressure in the Gulf of Gdańsk and the Vistula Lagoon

7 czerwca 2018 Grzegorz Kozlowski 0

This study describes the subfossil diatom flora in the surface sediments of the Polish coastal waters in relation to human impact. The material studied consists of the uppermost parts of seven sediment cores collected from […]

Hydrobiology

Reduction of nutrient emission from Polish territory into the Baltic Sea (1988–2014) confronted with real environmental needs and international requirements

7 czerwca 2018 Grzegorz Kozlowski 0

Eutrophication of the Baltic Sea is considered a major threat to its ecological status. We present and discuss Polish riverine flow normalized loads of total nitrogen (TN) and total phosphorus (TP) discharged into the Baltic […]

Hydrobiology

Distribution of ascaridoid nematodes (Nematoda: Chromadorea: Ascaridoidea) in fish from the Barents Sea

7 czerwca 2018 Grzegorz Kozlowski 0

The Ascaridoidea are parasites with heteroxenous life cycles. The study shows that fish can be paratenic, intermediate, or final hosts for parasites, and parasitic fauna reflects the feeding behavior of the hosts. Each species of […]

Hydrobiology

Size-fractionated chlorophyll a and phycocyanin temporal variations in a highly eutrophic lake and its isolated karstic springs

7 czerwca 2018 Grzegorz Kozlowski 0

Monthly variations of size-fractionated chlorophyll a and phycocyanin were studied in Lake Pamvotis between August 2016 and January 2017. Sampling was conducted at two sampling sites: in the main lake (Site 1: Lake) and in […]

Hydrobiology

Ascidian diversity (Chordata: Tunicata) from Andaman and Nicobar Islands, India

7 czerwca 2018 Grzegorz Kozlowski 0

Ascidians are filter-feeding sac-like marine urochordates of great evolutionary, ecological and economic importance. Andaman and Nicobar Islands are one of the most important hot spots of biodiversity in India, while the ascidian diversity of this region […]

Evaluation of genetic diversity and population structure of five yellow catfish Pelteobagrus fulvidraco populations by microsatellite markers

7 czerwca 2018 Grzegorz Kozlowski 0

Yellow catfish, Pelteobagrus fulvidraco, is an important commercial freshwater species in China. Knowledge about the genetic diversity of the yellow catfish is important to support the management and conservation programs, which would subsequently support the […]
