Exposure to contaminants, such as Persistent Organic Pollutants (POPs), is currently considered a serious anthropogenic threat to marine predators and their food webs. Exposure to contaminants by marine wildlife is mainly ...
Dimethylsulfide (DMS) and its algal metabolite precursor, dimethylsulfoproprionate (DMSP), are major players in the oceanic and atmospheric sulfur cycle. DMS is the most abundant volatile organic sulfur compound in the ...
In this thesis we studied how the changes in the climate determine the distribution, diversity and conservation of a very representative group of the Arctic avifauna, the shorebirds. In the first chapter we explored the ...
During brain development, UNC5 receptors play a key role in controlling axonal extension through their sensing of the guidance molecule Netrin-1. The correct positioning of receptors into specific cholesterol-enriched ...
Urinary tract infection (UTIs) is an extremely common disease. Proteus mirabilis is a common cause of UTI in individuals with functional or structural abnormalities or with long-term catheterization, it forms bladder and ...
