(Doktoravhandlinger ved NTNU, 1503-8181; 2005:101, Doctoral thesis, 2005)Studies on laboratory animals suggest that developing and newborn mammals are more vulnerable than the adults with respect to the harmful effects of organochlorine (OC) pollutants such polychlorinated biphenyls (PCBs) and ... -
Årsrapport fra NINAs Elgmerkingsprosjekt i grenseområdet Akershus, Hedmark og Østfold i 2004
(NINA rapport;12, Research report, 2005)Prosjektet ser på hvilke faktorer som påvirker bestandssvingningene i norske elgbestander. I denne regionen er prosjektet spesielt fokusert på hvordan en stedlig ulvebestand påvirker re-krutteringen til elgbestanden. Denne ... -
Implications of mate choice for the management of small populations : experimental studies using the guppy (Poecilia reticulata) as a model species
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:164, Doctoral thesis, 2005)This thesis aims to investigate the implication of mate choice for individual fitness in small populations. Specifically I address Allee effects, inbreeding and outbreeding by using the guppy (Poecilia reticulata) as a ... -

Salmonid fishes in a changing climate : the winter challenge
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:199, Doctoral thesis, 2005)In the present thesis, winter mortality was linked to levels of stored energy by a field study from a northern Atlantic salmon population where population frequency distributions for specific somatic energy were compared ... -
Functional characterisation of olfactory receptor neurone types in heliothine moths: Identification of molecular receptive ranges by the use of single cell recordings linked to gas chromatography and mass spectrometry
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:73, Doctoral thesis, 2005)When the study of this thesis was initiated, hardly any work had been carried out on how plant odour information was encoded by the olfactory RNs in heliothine moths. The method of gas chromatography linked to single cell ... -
