Article
Bernt-Erik Saether, Auteur ; Vidar Grotan, Auteur ; Steinar Engen, Auteur ; David G. Noble, Auteur ; Robert P. Freckleton, AuteurP> One of the greatest challenges in ecology is to develop tools that can give reliable projections of future population fluctuations as well as to quantity uncertainties. The population prediction interval (PPI), i.e. the stochastic interval th[...]

Jarle Tufto, Auteur ; Russell Lande, Auteur ; Thor-Harald Ringsby, Auteur ; Steinar Engen, Auteur ; Bernt-Erik Saether, Auteur ; Thomas R. Walla, Auteur ; Philip J. DeVries, Auteur1. We develop a Bayesian method for analysing markrecapture data in continuous habitat using a model in which individuals movement paths are Brownian motions, life spans are exponentially distributed and capture events occur at given instants in[...]
Article
Erling Johan Solberg, Auteur ; Henrik Jensen, Auteur ; Thor Harald Ringsby, Auteur ; Bernt-Erik Saether, AuteurGene transfer may occur following hybridization between closely related species if hybrids are viable and able to breed with individuals of one or both of the parental species. House (Passer domesticus) and tree sparrows (P. montanus) occasional[...]

Bernt-Erik Saether, Auteur ; Magnar Lillegard, Auteur ; Vidar Grotan, Auteur ; Mark C. Drever, Auteur ; Steinar Engen, Auteur ; Thomas D. Nudds, Auteur ; Kevin M. Podruzny, Auteur1. Geographic gradients in population dynamics may occur because of spatial variation in resources that affect the deterministic components of the dynamics (i.e. carrying capacity, the specific growth rate at small densities or the strength of d[...]

Bernt-Erik Saether, Auteur ; Vidar Grotan, Auteur ; Steinar Engen, Auteur ; David G. Noble, Auteur ; Robert P. Freckleton, AuteurP>1. Many patterns in macroecology are closely related to the total abundance of a species in a region. Here we show that interspecific differences in the pattern of population fluctuations of British bird species can be predicted from knowledge[...]
Article
Thor H. Ringsby, Auteur ; Torborg Berge, Auteur ; Bernt-Erik Saether, Auteur ; Henrik Jensen, AuteurParental care is assumed to be closely associated with individual differences in reproductive success. We investigated how feeding frequencies varied among parents and how this affected the subsequent reproductive success in insular populations [...]
Article
Vidar Grotan, Auteur ; Russell Lande, Auteur ; Steinar Engen, Auteur ; Bernt-Erik Saether, Auteur ; Phil J. DeVries, Auteur1. Studies of seasonality in ecological diversity rarely extend over more than a few years, and few studies of seasonal diversity have explicitly investigated the influence of environmental factors on seasonal community composition, especially i[...]

Bernt-Erik Saether, Auteur ; Steinar Engen, Auteur ; John Odden, Auteur ; John D. C. Linnell, Auteur ; Vidar Grotan, Auteur ; Henrik Andren, AuteurEurasian lynx in Scandinavia are subject to regular harvest and lethal control to reduce depredation on domestic livestock and semi-domestic reindeer. Here we introduce the use of total reproductive value to model the effects of current harvest [...]
