  2. 2. Resource use and consumption of three-spined sticklebacks (Gasterosteus aculeatus) under different environmental conditions during winter.

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : David Bystedt; [2013]
    Keywords : fish; consumption; light condition; winter; climate change;

    Abstract : In temperate climate with pronounced seasonality, ice and snow cover reduces light conditions during winter which in turn reduce search efficiency for visual feeding consumers like fish. Furthermore, a suggested major effect of future climate change is an increased input of allochtonous DOC to aquatic systems which causes an increased brownification and hence reduced overall light conditions.

    Keywords : PPAR; Atlantic salmon; fatty acid; PCR; ; qPCR; ; RT-PCR;

    Abstract : Peroxisome Proliferator-activated Receptors (PPARs) are ligand-inducible transcription factors, that can be activated by both dietary fatty acids and their metabolic derivates in the body, as by eicosanoids, hypolipidemic agents or antidiabetic drugs. To date three PPAR isotypes have been identified in mammals, birds, and amphibians, termed PPARα, PPARγ, and PPARβ/δ. READ MORE

    Abstract : Supplementary feeding is a widespread practice in Sweden. In most cases, this is done in order to increase ungulate densities for hunting purposes. Forest regimes can also provide a high amount of natural food which influences densities. But high densities are not unproblematic and can cause several problems, e. READ MORE
