   Sammanfattning : Shortage of food is an alarming problem today, with up to 821 million people that are undernourished world-wide. At the same time, enough edible foodstuff to feed 1.9 billion people are wasted or lost in the food supply chain that for aesthetic reasons, handling and transportation inadequacies in the food supply chain and lack of market.

3. 2. Complexity and Change in a Simple Food Web : Studies in the Baltic Sea (FAO Area 27.IIId)

   Författare :Henrik Österblom; Sture Hansson; Robert W Furness; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Avian cholera; Bottom-up; Bycatch; Clupea harengus; Ecosystem; Food web; Gadus morhua; Halichoerus grypus; Regime shift; Sprattus sprattus; Top-down; Trophic cascade; Uria aalge; Marine ecology; Marin ekologi;

   Sammanfattning : An influence at one trophic level can result in dynamic impacts also on other components of a food web. These dynamics are known as trophic cascades, and can be both top-down and bottom-up. After a near-collapse of the Baltic cod Gadus morhua stock in the 1980s, its main prey sprat Sprattus sprattus increased dramatically. LÄS MER

7. 5. Leptin endocrinology and energy homeostasis in salmonids

   Författare :Marcus Johansson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Leptin; Leptin binding-protein; Energy homeostasis; Oncorhynchus mykiss; Salvelinus alpinus; Adiposity; Food intake; Fasting; Refeeding; Catabolism; Anorexia;

   Sammanfattning : In salmonids, the physiological role of leptin is not completely elucidated. Nonetheless, the anorexigenic effect of leptin indicates a role in their energy homeostasis. This thesis focuses on advancing the understanding of the involvement of the leptin system in the regulation of energy homeo-stasis and food intake in teleost fish. LÄS MER
