Antimicrobial peptides in Urticina eques and Echinus esculentus. Isolation, characterisation, and structure-activity relationship studies
(Doctoral thesis; Doktorgradsavhandling, 2016-12-09)
Bacterial resistance to antibiotics has become a serious global problem. Infections that once were easily cured with antibiotics have now become nearly impossible to treat. Thus, there is a desperate need for new antibacterial drugs. Antimicrobial peptides (AMPs) are a diverse group of compounds. Amongst their unique features are their ability to kill bacteria (often both Gram-positive and Gram-negative) ...
Marine food-web structure and community patterns in high-latitude marine ecosystems
(Doctoral thesis; Doktorgradsavhandling, 2016-06-24)
This PhD deals with spatial and temporal community patterns in Barents Sea marine food webs and benthic communities in Svalbard. A main aim of this PhD project has been to study how community and food-web structure changes along environmental and climatic gradients, and to elucidate how species respond to climate warming in the Arctic. We used network analysis to study how the network of who eats ...
