Zatoka Pucka jest jednym z rejonów Bałtyku historycznie najbardziej narażonym na liczne presje antropogeniczne. Stąd już w latach 70. XX wieku pojawiły się pierwsze wzmianki o niekorzystnych zmianach zachodzących m.in. w zbiorowiskach makrofitobentosu. Jako jeden z przykładów istotnych zmian podawano zanik kluczowych gatunków glonów i roślin naczyn...

The Puck Lagoon is considered a well-recognised region of the southern Baltic Sea. Research in this area has been conducted since the beginning of the 20th century. However, after drastic changes in the Lagoon's ecosystem in the1980s, the intensity of research, especially on phytobenthos, decreased significantly. Encouraged by new observations indi...

The marine benthic cyanobacteria on coral reefs of Moorea Island (French Polynesia) show significant changes in species diversity in response to environmental impacts. To study these changes in cyanobacterial diversity, we examined pristine and degraded coral reefs by combining microscopy of morphological properties of the taxa with characterizatio...

The role of macroalgal allelopathy in aquatic systems has received increasing attention as a potential means of controlling cyanobacterial blooms. However, the allelopathic activity of Chara sp. on coexisting and bloom-forming picocyanobacteria is still largely unknown. Therefore, the laboratory experiments were conducted to investigate the allelop...

Nodularia spumigena is a nitrogen-fixing filamentous cyanobacteria in the Baltic Sea. Nodularin (NOD), the hepatotoxic peptide produced by this cyanobacterium, accumulates in the organisms from different trophic levels. In this paper, the effects of N. spumigena cell extract on the round goby (Neogobius melanostomus) was investigated under laborato...

Muscle and liver tissues of nine fish species were analyzed to assess butyltin and phenyltin contamination. The samples were collected from three basins located in the Southern Baltic Sea coastal zone that each represent different potential for organotin pollution. Maximum total concentrations of butyltin compounds (BTs) in the fish muscles and liv...

Although chaetognaths inhabiting polar ecosystems are relatively well known, there are few reports on their functioning in the Antarctic coastal plankton community. The presented results provide the first comprehensive description of population structure of chaetognaths in the neritic zone west of the Antarctic Peninsula. The studies were performed...

Trophic interactions between preadult and adult Pomatoschistus minutus and Pomatoschistus microps and young Platichthys flesus occurring in inshore waters of the Gulf of Gdańsk (Southern Baltic) We intended to estimate if shallow inshore waters of the Gulf of Gdańsk can be considered important feeding grounds for the fishes under investigation. We...

A study was conducted from 2001 to 2003 in the Gulf of Gdańsk (Poland) on the diel food composition and diel and seasonal changes in the feeding activity of Pomatoschistus minutus, Pomatoschistus microps, and Platichthys flesus. During the three-year study, no empty fish stomachs were noted, and the fish food was comprised exclusively of prey speci...

Sand and common goby specimens were collected from the costal waters in the vicinity of Sopot and Chałupy (Gulf of Gdańsk) from August to October. The relationship between the food consumed and the fish condition was investigated for both species using the Fulton and Clark factors, HSI, feeding intensity, and the index of relative importance. The r...
