Spatial variation in senescence rates in a bird metapopulation
Holand, Håkon; Kvalnes, Thomas; Gamelon, Marlène; Tufto, Jarle; Jensen, Henrik; Pärn, Henrik; Ringsby, Thor Harald; Sæther, Bernt-Erik (Journal article, 2016)Investigating factors which affect the decline in survival with age, i.e. actuarial senescence, is important in order to understand how demographic rates vary in wild populations. Although the evidence for the occurrence ... -
Spatiotemporal variation in laying date and its impact on reproductive success in house sparrows (Passer domesticus)
Johansen, Sonja Kristina Norum (Master thesis, 2018)Timing of breeding is an important determinant of reproductive success for animals living in seasonal environments. Understanding the factors affecting reproductive processes are necessary to predict how populations may ... -
Statistical methods for estimating fluctuating selection
Cao, Yihan (Doctoral theses at NTNU;2020:99, Doctoral thesis, 2020) -
Stochastic Volatility Models
Torkildsen, Thomas (Master thesis, 2023)I denne avhandlingen ble effektiviteten av Stokastiske Volatilitetsmodeller, med ARMA(p, q) log-volatilitet, undersøkt i forhold til GARCH(p, q) i å forutsi volatiliteten til finansielle tidsserier. Videre var målet å ... -
Temporal and spatial variation in prevalence of the parasite Syngamus trachea in a metapopulation of House Sparrows (Passer domesticus)
Holand, Håkon; Jensen, Henrik; Tufto, Jarle; Sæther, Bernt-Erik; Ringsby, Thor Harald (Journal article, 2013)When investigating parasite–host dynamics in wild populations, a fundamental parameter to investigate is prevalence. This quantifies the percentage of individuals infected in the population. Investigating how prevalence ... -
Ungulate population monitoring in an open tundra landscape:distance sampling versus total counts
Le Moullec, Mathilde; Pedersen, Åshild Ønvik; Yoccoz, Nigel Gilles; Aanes, Ronny; Tufto, Jarle; Hansen, Brage Bremset (Journal article; Peer reviewed, 2017)Researchers and wildlife managers strive for low bias and high precision (i.e. high accuracy) when estimating animal population sizes. Distance sampling is currently one of the most widely used monitoring methods. However, ... -
Varying disease-mediated selection at different life-history stages of Atlantic salmon in fresh water
de Eyto, E; McGinnity, P; Huisman, Jisca; Coughlan, J; Consuegra, S; Farrell, K; O´Toole, C; Tufto, Jarle; Megens, HJ; Jordan, W; Cross, T.; Stet, Rene J.M. (Journal article; Peer reviewed, 2011)Laboratory studies on associations between disease resistance and susceptibility and major histocompatibility (MH) genes in Atlantic salmon Salmo salar have shown the importance of immunogenetics in understanding the ...
