Northern cod (Gadus morhua) movement: insights from acoustic telemetry and genomics

Journal of Fish Biology, EarlyView.
Abstract Knowledge of the timing and diversity of fish movements within a commercially exploited stock complex is required to ensure the sustainability of fisheries. Although migration can be driven by environmental factors, genomic mechanisms also play an important role in this complex life‐history trait. The northern cod (Gadus morhua) stock complex,

Micropollutants in the Danube River Basin

Water Science and Technology, 1999
Monitoring programmes in river basins usually include monitoring heavy metals and selected organic micropollutants in water and sediment. Several survey results revealed contamination of the water resources in the Danube river basin. Besides those chemicals, for which regulations already exist, there are other compound classes, e.g., aromatic ...

Contribution to the knowledge on the distribution of freshwater sponges – the Danube and Sava rivers case study

Journal of Limnology, 2017
Sponges in the large rivers within the Danube River Basin (DRB) have not been adequately studied. Hence, the aim of this work was to undertake an investigation on the distribution of sponge species in the Danube and Sava rivers.

Relationship between the environment and the occurrence of invasive pumpkinseed Lepomis gibbosus in lotic and lentic habitats

Journal of Fish Biology, EarlyView.
Abstract The pumpkinseed Lepomis gibbosus is a freshwater fish species native to North America. It has been introduced to Europe, where it is recognized as one of the worst aquatic invaders due to its high adaptability and invasive potential. This study aimed to determine the presence of L. gibbosus in small to medium‐sized water bodies, both lotic and

Euglenophyta of the Danube River in Serbia

Archives of Biological Sciences, 2008
Most genera and many species of euglenophytes exist worldwide. They usually occur during the summer months in slow-flowing and stagnant waters, rich with organic substances. Euglenophytes of the Danube River in Serbia were studied at 16 localities during 2002-2003.

Governing Transnational Commons: How International Treaties and Multi‐Stakeholder Organizations Shape Cooperation and Conflict

Journal of Management Studies, EarlyView.
Abstract When common‐pool resources such as freshwater, clean air, and fisheries span national borders, the collective action problems encountered are particularly severe. This study explores the role of polycentric governance systems in overcoming these pressing problems, which frequently underlie global grand challenges. Integrating political economy

Maximal Swimming Speed Explains Differences in Habitat Use Among Invasive Ponto‐Caspian Dikerogammarus Species (Crustacea, Amphipoda)

Journal of Zoology, EarlyView.
The three invasive Ponto‐Caspian Dikerogammarus species (D. bispinosus, D. haemobaphes, and D. villosus) show niche differentiation along the current velocity gradient. In the present study, we experimentally measured their maximal swimming speeds to test whether they coincide with their tolerances for currents.
