Some Bosmina and Daphnia species have the ability to develop extreme morphological antipredator defences, such as long antennules, high carapaces and helmets. The relative sizes of these plastic traits may differ substantially ...

The Baltic Sea has been severely affected by pollution and resource overexploitation during the last centuries. The grey seal (Halichoerus grypus) is a good example of how a species can be affected by such changes. In the ...

According to the United Nations, plastic pollution in the natural environment has been identified as one of the biggest environmental challenges of this century and has become a cause for an emerging international concern. ...

Many toxic xenobiotics entering into the aquatic environment exert their effects through redox cycling. Oxidative stress, incorporating both antioxidant defences as well as oxidative damage, is a common effect in organisms ...

It is likely that fish in their natural environment are exposed to mixtures of several pharmaceuticals as well as other pollutants. This may result in adverse effects which are augmented due to the chemical interactions. ...

ABSTRACT Growth of marine organisms, fouling, on man-made constructions submerged in the water is regarded as a major problem. For vessels, fouling increases drag and thereby fuel consumption, wherefore antifouling ...

Physiologically controlled photocytes, capable of producing bioluminescence, are a common feature in the ocean among animals ranging from cnidarians to fish. The aim of this thesis was to study and compare the nature of ...
