Characteristics of morphodynamic conditions in the shallows of Puck Bay (southern Baltic Sea)

Puck Bay is an unusual and thus interesting coastal water region, as it combines two different environments – a lagoon and the sea. They differ from each other in their seabed morphology, salinity, dynamics and […]

Distribution of Didymosphenia, Gomphonema and Gomphosphenia diatoms (Bacillariophyta) in Turkish inland waters

In this study, a total of 53 taxa were identified from 13 catchments in Turkey. Gomphonema affine var. rhombicum E.Reichardt, G. angusticephalum E.Reichardt & Lange-Bertalot, G. calcifugum Lange-Bertalot & E.Reichardt, G. elegantissimum E.Reichardt & Lange-Bertalot, […]

Effects of copper and cadmium on physiology and antifouling defense of the marine macroalga Ulva reticulata

Heavy metals are major stressors for benthic macroalgal communities in marine ecosystems. In this study, the effects of copper and cadmium on some physiological parameters along with antifouling defense of the marine macroalga Ulva reticulata […]

The foraminiferal record in the Holocene evolution of the Mecklenburg Bay (south-western Baltic Sea)

Foraminiferal assemblages were analyzed in a 620-cm long core retrieved from the central part of the Mecklenburg Bay (MB, south-western Baltic Sea) to aid in the reconstruction of environmental changes occurring in the area during […]

Inter-clutch egg differences and androgenesis in rainbow trout (Oncorhynchus mykiss, Walbaum 1792)

Ionizing radiation (IR) is applied to inactivate the nuclear genome in rainbow trout eggs during induced androgenetic development. However, IR-generated reactive oxygen species (ROS) may affect developmental potential of eggs and reduce the effectiveness of […]

Incidence of skeletal deformities in induced triploid rainbow trout Oncorhynchus mykiss (Walbaum, 1792)

Due to the cytogenetic incompatibility, triploid fish are usually infertile and are not affected by a decline in growth, survival and meat quality, which accompanies the process of sexual maturation in diploid specimens. Thus, artificial […]

Distribution and ecology of two interesting diatom species Navicula flandriae Van de Vijver et Mertens and Planothidium nanum Bąk, Kryk et Halabowski in rivers of Southern Poland and their spring areas

In this paper, we report new records of rare diatoms that have recently been found in Southern Poland. Planothidium nanum was found only in the upper reaches of the Centuria River, which is not exposed […]

Stock mapping, size structure and biological parameters of the clam Polititapes aureus in the shellfish production area of the southern Tunisian waters (Central Mediterranean)

The clam Polititapes aureus is one of the most abundant shellfish species in the southern Tunisian waters. Its current exploitation status and management are becoming a major concern for fishing industry in Tunisia. The significant […]

Spatio-temporal variation of microphytoplankton communities in Obhur Creek, the central Red Sea

The abundance and distribution of microphyto-plankton and related physicochemical factors were assessed monthly in Obhur Creek, the central Red Sea. Sampling was carried out near the entrance, the middle and end parts of the creek. […]
