Long-term investigation of the ‘soft flesh’ condition in Northeast Atlantic mackerel induced by the myxosporean parasite Kudoa thyrsites (Cnidaria, Myxozoa): Temporal trends and new molecular epidemiological observations
(Journal article; Peer reviewed, 2022)Northeast Atlantic (NEA) mackerel (Scomber scombrus, Scombridae) represents an economically important target for the Norwegian pelagic fishing industry. Despite the commercial significance of NEA mackerel, little is known ... -
Long-term monitoring of a brown trout (Salmo trutta) population reveals kin-associated migration patterns and contributions by resident trout to the anadromous run
(Journal article; Peer reviewed, 2021)Background: In species showing partial migration, as is the case for many salmonid fishes, it is important to assess how anthropogenic pressure experienced by migrating individuals affects the total population. We focused ... -
Long-term Observations Reveal Environmental Conditions and Food Supply Mechanisms at an Arctic Deep-Sea Sponge Ground
(Journal article; Peer reviewed, 2021)Deep-sea sponge grounds are hotspots of benthic biomass and diversity. To date, very limited data exist on the range of environmental conditions in areas containing deep-sea sponge grounds and which factors are driving ... -
Long-term responses of benthic invertebrates to rotenone treatment
(Journal article; Peer reviewed, 2021)Biological invasions are regarded as one of the largest threats to native biodiversity. The eradication of alien invasive fish or parasites by culling of hosts is a controversial conservation strategy, particularly when ... -
Long-term trajectories of non-native vegetation on islands globally
(Journal article; Peer reviewed, 2023)Human-mediated changes in island vegetation are, among others, largely caused by the introduction and establishment of non-native species. However, data on past changes in non-native plant species abundance that predate ... -
Long-term trends in diatom diversity and palaeoproductivity: A 16 000-year multidecadal record from Lake Baikal, southern Siberia
(Journal article; Peer reviewed, 2022)Biological diversity is inextricably linked to community stability and ecosystem functioning, but our understanding of these relationships in freshwater ecosystems is largely based on short-term observational, experimental, ... -
Long-term welfare effects of repeated warm water treatments on Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2022)Warm water treatment has in recent years become widely used for ridding salmonids of sea lice in aquaculture although the consequences of the treatment for fish welfare are not adequately investigated. The objective of ... -
Longevity and growth of Acacia tortilis; insights from 14C content and anatomy of wood
(Peer reviewed; Journal article, 2007-06-15)Background: Acacia tortilis is a keystone species across arid ecosystems in Africa and the Middle East. Yet, its life-history, longevity and growth are poorly known, and consequently ongoing changes in tree populations ... -
Looking forward through the past: identification of 50 priority research questions in palaeoecology
(Peer reviewed; Journal article, 2014) -
Losing the ‘arms race’: multiresistant salmon lice are dispersed throughout the North Atlantic Ocean
(Journal article; Peer reviewed, 2021)Nothing lasts forever, including the effect of chemicals aimed to control pests in food production. As old pesticides have been compromised by emerging resistance, new ones have been introduced and turned the odds back in ... -
Loss of stomach, loss of appetite? Sequencing of the ballan wrasse (Labrus bergylta) genome and intestinal transcriptomic profiling illuminate the evolution of loss of stomach function in fish
(Peer reviewed; Journal article, 2018-03-06)Background: The ballan wrasse (Labrus bergylta) belongs to a large teleost family containing more than 600 species showing several unique evolutionary traits such as lack of stomach and hermaphroditism. Agastric fish are ... -
Lost in Translation? Multiple Discursive Strategies and the Interpretation of Sustainability in the Norwegian Salmon Farming Industry
(Journal article; Peer reviewed, 2020-04-04)The term ‘sustainability’ is vague and open to interpretation. In this paper we analyze how firms use the term in an effort to make the concept their own, and how it becomes a premise for further decisions, by applying a ... -
Lukket merdsystem - AquaDomen: Effekt på smittedynamikk
(Master thesis, 2012-06-04)Oppdrettsnæringen har blitt kritisert for å ha en negativ innvirkning på omliggende miljø, der smitteoverføring av ulike agens til ville laksepopulasjoner er et stort problem. Det er også reist bekymring ved den genetiske ... -
Lumpfish Cyclopterus lumpus reproduction: Pituitary gene expression, physiological and morphological changes accompanying gonadal maturation
(Journal article; Peer reviewed, 2022)Lumpfish is the most important cleanerfish species in Atlantic salmon farming. Detailed information on the gonadal maturation process is a prerequisite for year-round production of juvenile lumpfish. In the present study ... -
Macro and Microstructural Characteristics of North Atlantic Deep-Sea Sponges as Bioinspired Models for Tissue Engineering Scaffolding
(Journal article; Peer reviewed, 2021)Sponges occur ubiquitously in the marine realm and in some deep-sea areas they dominate the benthic communities forming complex biogenic habitats – sponge grounds, aggregations, gardens and reefs. However, deep-sea sponges ... -
Macroecological context predicts species' responses to climate warming
(Journal article; Peer reviewed, 2021)Context-dependencies in species' responses to the same climate change frustrate attempts to generalize and make predictions based on experimental and observational approaches in biodiversity science. Here, we propose ... -
Macromolecular sheets direct the morphology and orientation of plate-like biogenic guanine crystals
(Journal article; Peer reviewed, 2023)Animals precisely control the morphology and assembly of guanine crystals to produce diverse optical phenomena in coloration and vision. However, little is known about how organisms regulate crystallization to produce ... -
Macrozooplankton as feed source for farmed fish - growth, product quality and safety
(Doctoral thesis, 2006-12-14) -
Making predictions in a changing world: The benefits of individual-based ecology
(Peer reviewed; Journal article, 2015-12-17)Ecologists urgently need a better ability to predict how environmental change affects biodiversity. We examine individual-based ecology (IBE), a research paradigm that promises better a predictive ability by using ... -
Making the best of lousy circumstances: The impact of salmon louse Lepeophtheirus salmonis on depth preference of sea trout Salmo trutta
(Journal article; Peer reviewed, 2020)ABSTRACT: Sea trout are known for seeking out sources of freshwater to rid themselves of salmon lice. However, the effect of natural haloclines in fjords on parasite dynamics is not well understood. We tagged 48 naturally ...
