The objective of Oceanological and Hydrobiological Studies, an international journal published by the University of Gdańsk in cooperation with the Academic Publishing Company Walter DeGruyter, is to provide the most comprehensive and reliable source of information on the current knowledge in the fields of science related to both oceanology and hydrobiology. The main emphasis is on publishing high quality articles, easily available to scientists from all over the world. As an editorial team, we are convinced that Oceanological and Hydrobiological Studies will continue to grow as a journal meant for scientists and researchers who wish to keep abreast of the latest developments in these fields of science.
The use of 18S ribosomal DNA, ITS and rbcL molecular markers to study the genus Dunaliella (Dunaliellaceae) in Iranian samples: A phylogenetic approach
The microalga Dunaliella has been the focus of attention over recent decades owing to its high biotechnological potential for the production of β-carotene, biofuels and even as a good expression system for the production of
Heavy metals and 137Cs levels in macrophytes and temporal distribution in sediments – application for estuarine environment status assessment (Vistula Lagoon – southern Baltic)
The paper presents the first data on the concentrations of heavy metals (Cd, Pb, Zn, Cu, Ni, Cr, Mn) and 137Cs and their contamination ratios (CR) in the most abundant species of macrophytes in the
New records of Navicula sensu stricto from Serbia with taxonomic notes and autecological characterization of Navicula splendicula and N. moskalii
A total of 15 Navicula taxa were recorded in epilithic communities occurring in seven rivers of Serbia, all of which are new to the diatom flora of Serbia. The most interesting of them are N.
Marked contrast in wind-driven upwelling on the southeastern Nova Scotia coast in July of two years differing in ENSO conditions
Upwelling occurs on several coasts of the world, but it has mostly been studied on eastern ocean boundaries. We investigated upwelling on a western ocean boundary for which limited information exists. Using daily in-situ data
Demodex phocidi (Acariformes: Demodecidae) from Phoca vitulina (Carnivora: Phocidae) – the second observation in the world and a supplement to the species description
The present study describes a finding of the demodecid mite Demodex phocidi in the seal Phoca vitulina in the Baltic Sea. This is the first identification in Europe and the second in the world. This
Fishery resources are currently facing multiple stresses such as overfishing, pollution and climate change. Looking into processes and mechanisms of the dynamic fish community through detailed quantitative analyses contributes to effective conservation and management of
Diversity and biogeography of picoplankton communities from the Straits of Malacca to the South China Sea
Marine picoplankton, including prokaryotic and eukaryotic picoplankton, drive many biogeochemical processes, such as carbon, nitrogen and sulfur cycles, making them crucial to the marine ecosystem. Despite the fact that picoplankton is prevalent, its diversity and
Age, growth and reproductive biology of the saddled seabream (Oblada melanura) in the North Aegean Sea, Eastern Mediterranean
This study determines the length distribution, length–weight relationship, age, growth parameters, mortality rate, sex ratios, length at first maturity and reproduction of saddled seabream (Oblada melanura) collected monthly by fishermen around the Northern Aegean Sea
