Exploring Changes in Fishery Emissions and Organic Carbon Impacts Associated With a Recovering Stock
(Peer reviewed; Journal article, 2022) -
Exploring Living Nature : Modes of observation in history, teaching and learning
(Doctoral dissertations at University of Agder; no. 449, Doctoral thesis, 2024)The purpose of this study is to phenomenologically explore the practices of observing living nature in history, teaching, and learning, and to discuss potentials and constraints with teaching and learning observational ... -
Extracellular enzyme activity in the coastal upwelling system off Peru: A mesocosm experiment
(Peer reviewed; Journal article, 2023)The Peruvian upwelling system is a highly productive ecosystem with a large oxygen minimum zone (OMZ) close to the surface. In this work, we carried out a mesocosm experiment off Callao, Peru, with the addition of water ... -
The Fate of Phthalates in Surface Waters During Humus Removal by Precipitation
(Journal article; Peer reviewed, 2010)Phthalates are esters of aromatic 1,2 di-carboxylic acids and are widely found in surface waters and their removal is necessary because of their effects on human health. Humic material in water can adsorb phthalates and ... -
Feeding Ecology of Harbour Seals (Phoca vitulina) in Southern Norway
(Master thesis, 2017)In order to understand ecosystem dynamics and functions it is vital to have knowledge about relationships between predator and prey. Harbour seals (Phoca vitulina) are piscivorous marine mammals found at or near the top ... -
Feltstudie av makroalgevegetasjonen på Flekkerøy, Agder
(Master thesis, 2022)Makroalger spiller en sentral rolle i kysthabitater, på grunn av deres funksjon som økosystemingeniører, konkurrenter og primærprodusenter. De danner svært produktive habitater for forskjellige samfunn, og øker den ... -
Fiddler crabs and their above-ground sedimentary structures: a review
(Peer reviewed; Journal article, 2020)Fiddler crabs are abundant, semi-terrestrial crustaceans inhabiting tropical, subtropical and warm temperate coasts worldwide. Some species build above-ground sedimentary structures at or near the opening to their burrows. ... -
Field analysis of industrial development in a peripheral region of Norway
(Peer reviewed; Journal article, 2022)The paper explores how industrial development can occur in a peripheral region through the gradual development of strategic coherence between organisations, materiality, and agency. In a longitudinal case study of how the ... -
Fine-Scale Population Differences in Atlantic Cod Reproductive Success: A Potential Mechanism for Ecological Speciation in a Marine Fish
(Journal article; Peer reviewed, 2018) -
Fine-scale population dynamics in a marine fish species inferred from dynamic state-space models
(Journal article; Peer reviewed, 2017)Identifying the spatial scale of population structuring is critical for the conservation of natural populations and for drawing accurate ecological inferences. However, population studies often use spatially aggregated ... -
First estimates of metabolic rate in Atlantic bluefin tuna larvae
(Journal article; Peer reviewed, 2020) -
First record of the opal chimaera, Chimaera opalescens (Holocephali: Chimaeridae) and revision of the occurrence of the rabbitfish Chimaera monstrosa in the Azores waters
(Peer reviewed; Journal article, 2020)The presence of the opal chimaera, Chimaera opalescens, is reported for the first time in the deep waters of the Azores, with the capture of four specimens by fishermen and the video recording of an additional five ... -
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 ... -
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, ... -
Fishing for more data: Exploratory stock assessment of the data-limited brown crab (Cancer pagurus) stock in Norway
(Master thesis, 2022)Formal stock assessment is a key step in managing fisheries sustainably and preventing overexploitation (Hilborn, 2011). However, the majority of the world’s exploited stocks are considered data-limited and lack formal ... -
Fishing pressure impacts the abundance gradient of European lobsters across the borders of a newly established marine protected area
(Peer reviewed; Journal article, 2019) -
FishSizer: Software solution for efficiently measuring larval fish size
(Peer reviewed; Journal article, 2022)Length and depth of fish larvae are part of the fundamental measurements in many marine ecology studies involving early fish life history. Until now, obtaining these measurements has required intensive manual labor and the ... -
