Genetic population structure of the monogenean parasite Gyrodactylus thymalli and its host European grayling (Thymallus thymallus) in a large Norwegian lake
(Peer reviewed; Journal article, 2020-10-15)Understanding how populations are structured in space and time is a central question in evolutionary biology. Parasites and their hosts are assumed to evolve together, however, detailed understanding of mechanisms leading ... -
Genetic Structure of the Norwegian Parastagonospora nodorum Population
(Peer reviewed; Journal article, 2020-06-16)The necrotrophic fungal pathogen Parastagonospora nodorum causes Septoria nodorum blotch (SNB), which is one of the dominating leaf blotch diseases of wheat in Norway. A total of 165 P. nodorum isolates were collected from ... -
Genetic studies of fall armyworm indicate a new introduction into Africa and identify limits to its migratory behavior
(Peer reviewed; Journal article, 2022-02-04)The fall armyworm, Spodoptera frugiperda (J.E. Smith) is native to the Americas and a major pest of corn and several other crops of economic importance. The species has characteristics that make it of particular concern ... -
Genetic substructure and admixture as important factors in linkage disequilibrium-based estimation of effective number of breeders in recovering wildlife populations
(Journal article; Peer reviewed, 2017)The number of effective breeders (Nb) and effective population size (Ne) are population parameters reflective of evolutionary potential, susceptibility to stochasticity, and viability. We have estimated these parameters ... -
Genetic yield gains of winter wheat in Germany over more than 100 years (1895-2007) under contrasting fertilizer applications
(Journal article; Peer reviewed, 2018-09-27)For highly productive regions such as Germany, the increase of wheat grain yields observed throughout the 20th century is largely attributed to the progress in crop breeding and agronomic management. However, several studies ... -
Genetics and welfare in organic poultry production: A discussion on the suitability of available breeds and hybrids
(Bioforsk rapport;9(10) 2014, Research report, 2014-01-31)Organic production of eggs, broilers and turkey is regulated by international and national regulations and differs from conventional production. Breeds and hybrids selected for conventional production are also used in ... -
Genetisk variasjon i ask
(NIBIO POP;3(5) 2017, Others, 2017-02)De norske askeskogene er en nordlig utløper av større askeskoger i Europa som spredte seg nordover etter siste istid. Vi har undersøkt genetisk variasjon i ask (Fraxinus excelsior) og funnet at asken i Norge fulgte en ... -
