  1. 6. Remotely monitoring heart-rate and feeding behaviour of fish by using electronic sensor-tags

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Therese Arvén Norling; [2017]
    Nyckelord :bio-logging; remote monitoring; behaviour; electronic sensors; heart rate; acceleration;

    Sammanfattning : Modern electronic sensor tags (BioLoggers) can collect high resolution data on movement and physiology of fish. These tools make it possible to remotely monitor physiological stress responses as well as complex behaviours, such as feeding and hunting, in free swimming wild fish, data that often is difficult to collect by other means.

  5. 9. Is gear-based management of herbivorous fish a viable tool to prevent or reverse phase shifts in coral reefs? : Linking resilience theory to practice

    Master-uppsats, Stockholm Resilience Centre

    Författare :Quentin Dilasser; [2011]
    Nyckelord :Coral reefs; resilience; gear-based management; herbivores; preventers and reversers; phase shifts; fisheries; Zanzibar;

    Sammanfattning : Herbivorous reef fish are a key functional group for the ecological resilience of coral reefs. Asthey feed on algae, a major resource competitor of coral polyps, they can prevent and reversecoral-macroalgal phase shifts. LÄS MER
