Abstract:
... The integument of marine mammals provides an ideal substrate for colonization by photosynthetic epizoans. A review of the literature and new data from the harbor seal (Phoca vitulina richardsi) revealed at least eight genera of photosynthetic cyanobacteria and algae colonizing the pelage of six species of pinnipeds. The relationship may be considered a facultative association, beneficial to the ph ...

In 2010–2012 intensive fish surveys were performed in the Voordelta area and in 2009–2015 Cormorant pellets were sampled in the breeding colony of Breede Water, Voorne, four times per year between March and September. In total 48 fish species we ...

Abstract:
... Climate warming and associated physical and biological changes will likely force widespread species redistribution, particularly in polar environments. However, tracking such distributional shifts is difficult. The dietary habits of apex predators, like polar bears (Ursus maritimus), may provide early signals of distributional change in prey populations. We used harvest-based sampling to investiga ...

In Germany, BATV was found in mosquitoes and in one captive harbor seal, and antibodies were recently detected in various ruminant species. We have, therefore, conducted a follow-up study in ruminants from Saxony-Anhalt, the most ...
