Do ectomycorrhizal exploration types reflect mycelial foraging strategies?
(Journal article; Peer reviewed, 2022)Ectomycorrhizal exploration types are commonly assumed to denote spatial foraging patterns and resource-related niches of extraradical mycelia. However, empirical evidence of the consistency of foraging strategies within ... -
Documentation of growth and insulin-like growth factor I in Atlantic salmon (Salmo salar) post-smolts reared in large scale semi-closed and open systems
(Master thesis, 2017-06-27)Understanding the variation of growth performance in different large scale production scenarios is of great importance to the aquaculture industry to develop efficient rearing procedures for cultured fish. This study ... -
Does density influence relative growth performance of farm, wild and F1 hybrid Atlantic salmon in semi-natural and hatchery common garden conditions?
(Peer reviewed; Journal article, 2016-07)The conditions encountered by Atlantic salmon, Salmo salar L., in aquaculture are markedly different from the natural environment. Typically, farmed salmon experience much higher densities than wild individuals, and may ... -
Does pollen-assemblage richness reflect floristic richness? A review of recent developments and future challenges
(Peer reviewed; Journal article, 2016-05)Current interest and debate on pollen-assemblage richness as a proxy for past plant richness have prompted us to review recent developments in assessing whether modern pollen-assemblage richness reflects contemporary ... -
Does size matter? A bioeconomic perspective on optimal harvesting when price is size-dependent
(Peer reviewed; Journal article, 2011-09-09)Body size is a key parameter influencing demographic characteristics of fish populations as well as market value of landed catch. Yet in bioeconomic modelling body size is often an overlooked biological and economic ... -
Does snail grazing affect growth of the old forest lichen Lobaria pulmonaria?
(Peer reviewed; Journal article, 2006)Grazing marks from snails are frequently observed in populations of the old forest epiphyte Lobaria pulmonaria. However, grazing marks are more numerous in thalli from deciduous broadleaved forests than in thalli from ... -
Does the thermal component of warm water treatment inflict acute lesions on Atlantic salmon (Salmo salar)?
(Journal article; Peer reviewed, 2021)Warm water treatment, i.e. exposure to sea water at a temperature of 28–34 °C for 20–30 s, has in recent years been widely used for delousing of Atlantic salmon (Salmo salar) and rainbow trout (Oncorhynchus mykiss) in ... -
Does vaterite otolith deformation affect post-release survival and predation susceptibility of hatchery-reared juvenile Atlantic Salmon?
(Journal article; Peer reviewed, 2021)Sagittal otoliths are calcareous structures in the inner ear of fishes involved in hearing and balance. They are usually composed of aragonite; however, aragonite can be replaced by vaterite, a deformity which is more ... -
Domesticated escapees on the run: The second-generation monitoring programme reports the numbers and proportions of farmed Atlantic salmon in >200 Norwegian rivers annually
(Peer reviewed; Journal article, 2019)Norway is the world’s largest producer of farmed Atlantic salmon and is home to ∼400 rivers containing wild salmon populations. Farmed escapees, a reoccurring challenge of all cage-based marine aquaculture, pose a threat ... -
Domestication-induced reduction in eye size revealed in multiple common garden experiments: The case of Atlantic salmon (Salmo salar L.)
(Journal article; Peer reviewed, 2021)Domestication leads to changes in traits that are under directional selection in breeding programmes, though unintentional changes in nonproduction traits can also arise. In offspring of escaping fish and any hybrid progeny, ... -
Dominating sublittoral fish species in a west Norwegian fjord and their trophic links to cod (Gadus morhua L.)
(Peer reviewed; Journal article, 1993)The fish fauna in the sublittoral habitat of Masfjorden, western Norway, has been studied in order to reveal survival and growth prospects of released juvenile cod in a large-scale stock enhancement experiment. Seasonal ... -
Downregulation of N-terminal acetylation triggers ABA-mediated drought responses in Arabidopsis
(Peer reviewed; Journal article, 2015-07-17)N-terminal acetylation (NTA) catalysed by N-terminal acetyltransferases (Nats) is among the most common protein modifications in eukaryotes, but its significance is still enigmatic. Here we characterize the plant NatA ... -
