  3. 22. Women in the Seascape : Gender, Livelihoods and Management of Coastal and Marine Resources in Zanzibar, East Africa

    Författare :Sara Fröcklin; Maricela de la Torre-Castro; Lars Lindström; Nils Kautsky; Meryl J. Williams; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gender; fisheries; invertebrate harvesting; seaweed farming; coastal and marine management; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : All over the world, coastal populations depend on, and influence, the environment in pursue of their livelihoods. Managing the environment, while meeting the growing demand for marine resources, is a challenge. It further requires knowledge about all actors. LÄS MER

  4. 23. Effects of contrasting types of marine protected areas on seagrass- and coral communities : are community-based reserves an important complement to government-managed protected areas?

    Författare :Angelica Chirico; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : Coastal ecosystems, including seagrass beds and coral reefs, are among the most ecological and economical important ecosystems on Earth. At the same time as these ecosystems support livelihoods of coastal communities they are being highly degraded worldwide. LÄS MER

  5. 24. Processing of berries – Effects on functionality, stability and bioactivity of anthocyanins

    Författare :Gabriel Barbosa; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; berries; powder; hot air and microwave drying; osmotic dehydration; press cake; edible coating; anthocyanins; gastrointestinal in vitro digestion; polyphenols; pulsed electric field; oxidative stress; yeast;

    Sammanfattning : Berries are rich natural sources of anthocyanins, water-soluble pigments in plants that have been linked to beneficial effects against chronic diseases, such as cardiovascular diseases, type 2 diabetes and neurodegenerative diseases. However, anthocyanins as well as other polyphenolic compounds are often sensitive to degradation during processing, storage and digestion. LÄS MER

  7. 25. Behaviour and life-history responses to chick provisioning under risk of nest predation

    Författare :Sönke Eggers; David Winkler; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Chick provisioning; clutch size; delayed dispersal; nest concealment; nest predation; parental care; population decline; Perisoreus infaustus; Siberian jay; Biologi; Biology; Biologi; populationsbiologi; Population Biology;

    Sammanfattning : This thesis examines risk management in breeding Siberian jays (Perisoreus infaustus), which is indigenous to the northern taiga. Parent behaviour and the nest are cryptic. A new nest is built each year. It is placed on spruce or pine branches close to the trunk and well insulated with lichens, feathers and reindeer hair. LÄS MER
