Functional characterisation of olfactory receptor neurons in cabbage moth, Mamestra brassicae L. (Lepidoptera, Noctuidae). Gas chromatography linked to single cell recordings and mass spectrometry
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:163, Doctoral thesis, 2007)Most of us are well aware of the many odours surrounding us in nature and enjoy the pleasant smell of flowers or culinary herbs. In evolutionary context the sense of smell is considered as the oldest of our senses and is ... -
Demographic variation, distribution and habitat use between wildebeest sub-populations in the Serengeti National Park, Tanzania
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:191, Doctoral thesis, 2007)This thesis investigates the demographic variation, distribution and wildebeest habitat use in the Serengeti National Park (SNP) and its adjacent protected areas in northern Tanzania. Specifically, the study i) examines ... -
Spatial and temporal variation in herbivore resources at northern latitudes
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:144, Doctoral thesis, 2007)Herbivores may affect plants directly through foraging, trampling and fertilization or indirectly through altered competitive relationships between plant species. In addition, herbivores may cause indirect interactions ... -

Vurdering av GellyFeed metoden som hygienisering ved bruk av akvakulturdyr i fôr til akvakulturdyr. Uttalelse fra Faggruppe for fôr til terrestriske og akvatiske dyr i Vitenskapskomiteen for mattrygghet
(VKM Report;, Research report, 2008)Stiftelsen Rubin (senere GellyFeed AS) har siden 1991 jobbet med å utvikle fôr basert på avskjær fra villfisk til bruk i fôr til oppdrettsfisk. På grunn av fare for smitteoverføring, ble det utviklet et eget fôrkonsept ... -
The role of platelet activating factor in activation of growth arrested keratinocytes and re-epithelialisation
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:179, Doctoral thesis, 2008)Skin disorders such as psoriasis and chronic wounds are characterised by chronic inflammation accompanied by hyper-proliferation. Inflammation and proliferation are also phases in normal cutaneous wound healing. Upon ... -

A survey of NRPS genes from Planktothrix in Lake Kolbotnvannet
(Master thesis, 2008)Lake Kolbotnvannet is dominated by the Cyanobacteria Planktothrix. Cyanobacteria produce oligopeptides by nonribosomal peptide synthetases (NRPS), which have unknown biological functions. NRPS genes encoding the NRPS ... -
A mixture model approach to sample size estimation in two- sample comparative microarray experiments
(Journal article; Peer reviewed, 2008)Background: Choosing the appropriate sample size is an important step in the design of a microarray experiment, and recently methods have been proposed that estimate sample sizes for control of the False Discovery Rate ... -
The Svalbard reindeer (Rangifer tarandusplatyrhynchus) and its food base: plant-herbivoreinteractions in a high-arcticecosystem
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:17, Doctoral thesis, 2008)One challenge in ecology is to predict long-term effects of high herbivore densities on the vegetation, and its feedback consequences. I examined plant-herbivore dynamics during a 26-year period following reintroduction ... -
Skrekkblandet fryd:: Elevers fryktreaksjoner i et fagdidaktisk og evolusjonært perspektiv
(Master thesis, 2008)Denne oppgaven ser på 9.klasse elevers fryktreaksjoner i et fagdidaktisk og evolusjonært perspektiv. Fryktreaksjoner har helt siden Erasmus Darwins(1731-1802) tid blitt sett på som en beskyttelses- og overlevelsesstrategi. ... -
Tree thinking cannot taken for granted: challenges for teaching phylogenetics
(Journal article; Peer reviewed, 2008)Tree thinking is an integral part of modern evolutionary biology, and a necessary precondition for phylogenetics and comparative analyses. Tree thinking has during the 20th century largely replaced group thinking, de ... -
