Impact of fertilization on field vegetation and litter layer in a boreal forest
(Master thesis, 2017)Fertilization of Norwegian boreal forests to increase carbon uptake is suggested as a measure to reduce CO2 emissions. However, studies of the effects of fertilization on field vegetation and litter layer in these forests ... -
Impact of frequent cutting of trees in power-line corridors on biological diversity of beetles (Coleoptera)
(Master thesis, 2012-08-06)Abstract Compared to closed-canopy forest, power-line corridors are more frequently disturbed through regular cutting of all trees. The habitat is thus maintained in an early successional stage, with much sun exposed ... -
Individually characteristic corncrake Crex crex song reveals long-distance movements within the breeding season
(Master thesis, 2011-04-28)Due to modern agricultural practices, the corncrake is a species of global conservation concern. Mowing of meadows may cause corncrakes to make movements within one breeding season, but such movements are in general poorly ... -
Individuell vekstrate og byttefiskkonsum er bestemmende for kvikksølvkonsentrasjon i abbor (perca fluviatilis), gjedde (Esox lucius) og gjørs (Stizostedion lucioperca) i Øyeren.
(Master thesis, 2011-10-14)Kvikksølvkonsentrasjon, diett (byttedyr), individuelle vekstrater og trofisk posisjon (bestemt med stabile isotoper) ble undersøkt hos abbor (Perca fluviatilis), gjedde (Esox lucius) og gjørs (Stizostedion lucioperca) og ... -
