Bridging the ensemble Kalman filter and particle filters: the adaptive Gaussian mixture filter
Stordal, Andreas Størksen; Karlsen, Hans A.; Nævdal, Geir; Skaug, Hans J.; Vallès, Brice (Peer reviewed; Journal article, 2010)The nonlinear filtering problem occurs in many scientific areas. Sequential Monte Carlo solutions with the correct asymptotic behavior such as particle filters exist, but they are computationally too expensive when working ... -
A comparison of Monte Carlo sampling methods for metabolic network models
Fallahi, Shirin; Skaug, Hans J.; Alendal, Guttorm (Journal article; Peer reviewed, 2020)Reaction rates (fluxes) in a metabolic network can be analyzed using constraint-based modeling which imposes a steady state assumption on the system. In a deterministic formulation of the problem the steady state assumption ... -
Determining individual variation in growth and its implication for life-history and population processes using the Empirical Bayes method
Vincenzi, Simone; Mangel, Marc; Crivelli, Alain J.; Munch, Stephan; Skaug, Hans J. (Peer reviewed; Journal article, 2014-09-11)The differences in demographic and life-history processes between organisms living in the same population have important consequences for ecological and evolutionary dynamics. Modern statistical and computational methods ... -
Drivers of the summer-distribution of Northeast Atlantic mackerel (Scomber scombrus) in the Nordic Seas from 2011 to 2017; a Bayesian hierarchical modelling approach
Nikolioudakis, Nikolaos; Skaug, Hans J.; Olafsdottir, Anna H.; Jansen, Teunis; Jacobsen, Jan Arge; Enberg, Katja (Peer reviewed; Journal article, 2019-03)Identifying factors that are statistically correlated with the geographical distribution dynamics of a species can facilitate our understanding of causal physiological and ecological relationships. Northeast Atlantic (NEA) ... -
Experimental design for parameter estimation in steady-state linear models of metabolic networks
Frøysa, Håvard G; Skaug, Hans J.; Alendal, Guttorm (Journal article; Peer reviewed, 2020-01)Metabolic networks are typically large, containing many metabolites and reactions. Dynamical models that aim to simulate such networks will consist of a large number of ordinary differential equations, with many kinetic ... -
Genotyping errors in a calibrated DNA register: implications for identification of individuals
Haaland, Øystein; Glover, Kevin; Seliussen, Bjørghild Breistein; Skaug, Hans J. (Peer reviewed; Journal article, 2011-04-20)Background: The use of DNA methods for the identification and management of natural resources is gaining importance. In the future, it is likely that DNA registers will play an increasing role in this development. ... -
Good ethics or political and cultural censoring in science?
Torrissen, Ole; Glover, Kevin; Haug, tore; Misund, Ole Arve; Skaug, Hans J.; Kaiser, Matthias (Peer reviewed; Journal article, 2012)Peer-reviewed journals are the cornerstones to communicating scientific results. They play a crucial role in quality assurance through the review process, but they also create opportunities for discussions in the scientific ... -
Hybrids between common and Antarctic minke whales are fertile and can back-cross
Glover, Kevin; Kanda, Naohisa; Haug, Tore; Pastene, Luis A.; Øien, Nils Inge; Seliussen, Bjørghild Breistein; Sørvik, Anne Grete Eide; Skaug, Hans J. (Peer reviewed; Journal article, 2013-04-15)Background: Minke whales are separated into two genetically distinct species: the Antarctic minke whale found in the southern hemisphere, and the common minke whale which is cosmopolitan. The common minke whale is further ... -
Investigating population genetic structure in a highly mobile marine organism: The minke whale Balaenoptera acutorostrata acutorostrata in the North East Atlantic
Sanchez, Maria Quintela; Skaug, Hans J.; Øien, Nils Inge; Haug, Tore; Seliussen, Bjørghild Breistein; Solvang, Hiroko Kato; Pampoulie, Christophe; Kanda, Naohisa; Pastene, Luis A.; Glover, Kevin (Peer reviewed; Journal article, 2014-09-30)Inferring the number of genetically distinct populations and their levels of connectivity is of key importance for the sustainable management and conservation of wildlife. This represents an extra challenge in the marine ... -
Validation of close‐kin mark–recapture (CKMR) methods for estimating population abundance
Ruzzante, Daniel E.; McCracken, Gregory R; Førland, Brage; MacMillan, John; Notte, Daniela; Buhariwalla, Colin; Mills Flemming, Joanna; Skaug, Hans J. (Peer reviewed; Journal article, 2019)1. Knowing how many individuals there are in a population is a fundamental problem in the management and conservation of freshwater and marine fish. We compare abundance estimates (census size, Nc) in seven brook trout ... -
Whole genome resequencing reveals diagnostic markers for investigating global migration and hybridization between minke whale species
Malde, Ketil; Seliussen, Bjørghild Breistein; Sanchez, Maria Quintela; Dahle, Geir; Besnier, Francois; Skaug, Hans J.; Øien, Nils Inge; Solvang, Hiroko Kato; Haug, Tore; Skern-Mauritzen, Rasmus; Kanda, Naohisa; Pastene, Luis A.; Jonassen, Inge; Glover, Kevin (Peer reviewed; Journal article, 2017-01-13)Background: In the marine environment, where there are few absolute physical barriers, contemporary contact between previously isolated species can occur across great distances, and in some cases, may be inter-oceanic. An ...
