Underwater noise emitted during small-scale air entrainment events
The breaking wave phenomenon significantly takes part in the mechanisms of mass, heat and gas exchange at the air-water boundary and depends on the wind velocity. Some of the energy dissipated during this process is
Reproductive biology of the black-striped pipefish Syngnathus abaster Risso, 1827 (Pisces: Syngnathidae) in the Aegean Sea of Turkey
The paper presents the results of research on the reproductive biology of Syngnathus abaster – a species distributed in Çandarlı Bay. For this purpose, seine nets were collected from a depth of 0.5–2 m in
Rare calciphilous diatoms from the genus Gomphonema (Bacillariophyta) in lotic waters of SE Poland
The aim of this work was to present a morphological description and ecological characteristics of a rare species from the Gomphonema genus, occurring in calcium-rich waters, along with its new occurrence sites. The research was
Rapid expansion of the Asian clam Corbicula fluminea (O. F. Müller, 1774): a new alien species in the mollusk community of the Vistula
A new large population of the Asian clam Corbicula fluminea (O. F. Müller, 1774) was found within a reach (ca 210 km long) of one of the largest European rivers, the Vistula. The largest population
Predicting chlorophyll-a concentrations in two temperate reservoirs with different trophic states using Principal Component Regression (PCR)
Relationships between chlorophyll-a (chl-a) concentrations and 16 physicochemical variables in temperate eutrophic Çaygören and mesotrophic Ikizcetepeler reservoirs (Turkey) were determined using Principal Component Analysis (PCA). PCA was used to simplify the complexity of relationships between
Periodic events of Potamogeton alpinus in NW Poland (Pomerania region)
We have determined the timing of periodic events, such as leaf formation, flowering, fruiting and wintering of the aquatic plant Potamogeton alpinus. This study was performed in 15 watercourses situated in NW Poland in 2014–2015.
