1. 11. Macroalgal community dynamics on coral reefs : Implications for management

   Författare :Erik Mörk; Nils Kautsky; Magnus Nyström; Tim R. McClanahan; Stein Fredriksen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Macroalgae; Coral Reefs; Herbivory; Nutrients; Ecosystem change; Fish; Sea Urchins; East Africa; marin ekotoxikologi; Marine Ecotoxicology;

   Sammanfattning : Although rather inconspicuous on healthy coral reefs, macroalgae form the basis of coral food webs. Today, macroalgae are generally increasing and many reefs undergo transitions from coral to macroalgal dominance resulting from e.g. enhanced nutrient loading or increased fishing. LÄS MER

3. 12. Upholding the coral loop : Resilience, alternative stable states and feedbacks in coral reefs

   Författare :Albert Norström; Magnus Nyström; Nancy Knowlton; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; resilience; alternative stable states; regimes; feedbacks; recruitment; coral reefs; marine ecosystem management; regime shifts; phase shifts; Marine ecology; Marin ekologi; naturresurshushållning; Natural Resources Management;

   Sammanfattning : Coral reefs are suffering unprecedented declines in coral cover and species diversity. These changes are often associated with  substantial shifts in community structure to new dominant organisms. Ultimately, these “phase shifts” can be persistent and very difficult to return from.

4. 13. Effects of exercise in different phases after stroke

   Författare :Klas Sandberg; Paul Enthoven; Magnus Wijkman; Fredrik Nyström; Anna Danielsson; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Background: Stroke is a complex disease that can vary in severity. After a stroke, patients often have long-term disabilities that require major rehabilitation efforts. Evaluation of treatment and methods are important for development of effective rehabilitation after stroke. LÄS MER

5. 14. Influence of fruit, meal distribution and dental health on cardio-metabolic risk

   Författare :Edvin Ström; Fredrik H Nyström; Magnus Wijkman; Anders Gustafsson; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Background   Fruit is often recommended as a snack between meals and a main component of the cardioprotective Mediterranean diet. The sugar content might be of concern since it theoretically could lead to hepatic fat accumulation and affect dental status negatively. LÄS MER

7. 15. Fish for Food and Ecosystem Function : Fisheries, Trade and Key Ecosystem Processes in Coral Reefs

   Författare :Matilda Thyresson; Magnus Nyström; Edward H. Allison; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fish; food; key ecosystem processes; functional groups; coral reefs; trade; gear; small-scale fisheries; social-ecological systems; Zanzibar; Tanzania; Western Indian Ocean; naturresurshushållning; Natural Resources Management;

   Sammanfattning : Fish is a key source of food and income to millions of people living along tropical coastlines. They also play essential roles underpinning key ecosystem processes in coral reefs. For example, herbivorous fish keep algae in check that otherwise may outcompete corals, reducing the reef’s social-ecological values. LÄS MER
