Spatial patterns of phylogenetic and species diversity of fennoscandian vascular plants in protected areas
(Peer reviewed; Journal article, 2023)Protected areas are one of the main strategic means for conserving biodiversity. Yet, the design of protected areas usually neglects phylogenetic diversity, an important diversity measure. In this paper we assess the ... -
Evidence of hybridization between genetically distinct Baltic cod stocks during peak population abundance(s)
(Peer reviewed; Journal article, 2023)Range expansions can lead to increased contact of divergent populations, thus increasing the potential of hybridization events. Whether viable hybrids are produced will most likely depend on the level of genomic divergence ... -
Fish community dynamics in a coastal no-take marine protected area compared to a harvested area before and after protection from fishing
(Peer reviewed; Journal article, 2023)An ecosystem's ability to maintain key functions during environmental change is largely determined by its biodiversity. We compared fish species composition, richness, diversity, catch per unit effort (CPUE), and fish size ... -
Movement diversity and partial sympatry of coastal and Northeast Arctic cod ecotypes at high latitudes
(Peer reviewed; Journal article, 2023)Movement diversity within species represent an important but often neglected, component of biodiversity that affects ecological and genetic interactions, as well as the productivity of exploited systems. By combining ... -
Linking extreme seasonality and gene expression in Arctic marine protists
(Peer reviewed; Journal article, 2023)At high latitudes, strong seasonal differences in light availability affect marine organisms and regulate the timing of ecosystem processes. Marine protists are key players in Arctic aquatic ecosystems, yet little is known ... -

The acoustic repertoire of Atlantic cod (Gadus morhua) and the effect of feeding on broadband clicks and their sound characteristics
(Master thesis, 2023)Populations of Atlantic cod (Gadus morhua) along the Skagerrak coast remain below viable levels today despite various implemented management strategies aimed at their recovery. Augmented management approaches are needed ... -
How genomics can help biodiversity conservation
(Peer reviewed; Journal article, 2023)The availability of public genomic resources can greatly assist biodiversity assessment, conservation, and restoration efforts by providing evidence for scientifically informed management decisions. Here we survey the main ... -
Three decades of change in the Skagerrak coastal ecosystem, shaped by eutrophication and coastal darkening
(Peer reviewed; Journal article, 2023)Global coastal ecosystems are under accelerating pressure from human activities and climate change. In this study we explore a long-term time series (mostly 1990–2016) from major Norwegian rivers, together with coastal ... -
Combining modeling with novel field observations yields new insights into wintertime food limitation of larval fish
(Peer reviewed; Journal article, 2023)Recruitment success of marine fishes is generally considered to be highly dependent on larval growth and survival. In temperate ecosystems, fish larvae are sensitive to food limitation during the low productivity seasons, ... -
Marine primary producers in a darker future: a meta-analysis of light effects on pelagic and benthic autotrophs
(Peer reviewed; Journal article, 2023)The availability of underwater light, as primary energy source for all aquatic photoautotrophs, is (and will further be) altered by changing precipitation, water turbidity, mixing depth, and terrestrial input of chromophoric ... -
Haulout patterns of harbour seal (Phoca vitulina) colonies in the Norwegian Skagerrak, as monitored through time-lapse camera surveys
(Master thesis, 2023)Harbour seals (Phoca vitulina) are a part of the Norwegian coastal ecosystem and are distributed along the coastline, amongst the humans inhabiting and/or visiting these areas. We need to gain a better understanding of how ... -
A Global Perspective on Microplastic Concentrations and Characteristics in Sediment and Biota in Marine Coastal Areas
(Master thesis, 2023)Microplastic (MP, < 5 mm) has become an omnipresent environmental pollutant due to inappropriate management since the invention of plastic during the 1800s. MPs are now detected in all environmental matrices, with marine ... -
Gytetid hos laks (Salmo salar). - Skjer det en endring som følge av klimaendringer?
(Master thesis, 2023)Gytetid hos Atlanterhavslaks i norske vassdrag ble i 1988 studert av Tor G. Heggberget. Han fant at tiden laksen gyter på varierer fra midten av oktober til midten av januar, og at laksen gyter på gjennomsnittstemperaturer ... -
Fishing for Answers: A Historical Analysis of 150 Years of Fisheries landings in Skagerrak
(Master thesis, 2023)Norge blir ofte betraktet som et ledende eksempel på bærekraftig fiskeriforvaltning. Allikevel tilsier historien at det ikke alltid har vært slik, men skiftende referanserammer etter flere tiår med utvikling i fiskerinæringen, ... -
Designing a species-specific method, based on analysis of eDNA, for detection of lesser weever fish, and testing it at chosen locations along the coastline of Agder, Southern Norway
(Master thesis, 2023)Temperature is largely influencing species dispersion, and when the temperature conditions within an area are changing, species populations often respond by moving to other, more suitable areas. Such behavior has often ... -
Analyzing the reliability of citizen science information using Pacific oysters as a model system
(Master thesis, 2023)Det biologiske mangfolds krisen har ført til at mange arter har blitt utryddet de siste 20 årene; En av årsakene til dette er økende nærvær av fremmede arter. Mange av disse artene er uidentifiserte, noe som gjør det ... -
Behavioral reactions to H2S in farmed Salmon
(Master thesis, 2023)I resirkulerende akvakulturanlegg kan dannelse av hydrogensulfid (H2S) føre til akutt massedød av laks. Det er begrenset med kunnskap om hvordan fisk reagerer på H2S ved lave konsentrasjoner. Automatisk tolking av adferd ... -
