    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; acoustic telemetry; hatchery; life history; migration mortality; regulated rivers; Salmo salar; salmon; smolt; trout; Biology; Biologi;

    Abstract : Atlantic salmon Salmo salar has a complex life cycle, including long migrations and habitat shifts for both juveniles and adults. As such, salmon populations are vulnerable to habitat degradation and fragmentation along their migratory routes. READ MORE

    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Leptin; leptin receptor; Atlantic salmon; Salmo salar; sexual maturation; puberty; energy balance; hepatocytes; sex steriods; Biology with specialization in Comparative Physiology; Biologi med inriktning mot jämförande fysiologi;

    Abstract : Leptin is a peripheral adiposity signal and a key hormone in energy balance regulation in mammals, acting as a link between nutritional status and the endocrine reproductive axis. If this is also the role of leptin in fish is not fully understood. READ MORE

  4. 4. The role of leptin in zebrafish (Danio rerio) : Novel insights into appetite regulation and reproduction

    Author : Emmanouil Tsakoumis; Monika Schmitz; Tatjana Haitina; Åsa Wallén-Mackenzie; Ana Gómez Peris; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; zebrafish; leptin; appetite; GRN; brain; reproduction; oocyte maturation; ovulation; Biology with specialization in Comparative Physiology; Biologi med inriktning mot jämförande fysiologi;

    Abstract : The hormone leptin is a peripheral metabolic signal and an important regulator of energy balance. In mammals, leptin acts on the appetite centers in the hypothalamus, causing anorexigenic functions by inhibiting food intake. It is also considered as a link between the nutritional status and the endocrine reproductive axis. READ MORE
