Research has developed from zooplankton population dynamics, development of estimation techniques, and marine ecosystem modeling to a current interest in developing analytical as well as simulation models in biological oceanography. Examples are models of microbial nutrient uptake, euphotic zone properties, habitat properties of plankton and fish, and the competitive relationship between visual and tactile predators. In recent years this interest has led to a number of theoretical and field studies exploring hypotheses on how changes in optical properties affect marine ecosystems.

I am working on physical processes in fjords and the carrying capacity of the ecosystem especially in terms of aquaculture. Important for this is the variability of currents for dispersion of pathogenes, pollution and water quality properties, and the variability of temperature for determination of biological growth. It is necessary to understand the variability of today’s climate in order to evaluate the influence of a future climate change. I use both coupled physical-biological numerical models and collect field data in my work.

My research incorporates bio-socio-economic data to study the feedback between fishing strategies, economic and socia returns and the target fish stocks. At the same time, I am very interested in the political aspects of fishing, including how marine governance and spatial planning are advised and formulated in national and international agreements as harvest control rules or holistic ecosystem management plans. I use a systems-oriented viewpoint to examine different harvest strategies, and social network analyses to understand how knowledge is formed and used in science/advice systems that manage human activity in our ocean.

My PhD project focuses on larval cod in environmental gradients: how do recruitment success relate to oceanographic conditions? The aim is to develop theoretical models of larval cod growth and survival in scenarios of future oceanographic conditions. The key research question is how recruitment success of larval cod will depend upon changes in environmental and ecological gradients such as ocean temperature, alkalinity, primary production, optics and prey availability. Particular attention will be given to changes in vertical environmental gradients and behavioural strategies as well as horizontal patterns and drift.

My research is focused on understanding behavioral decisions, and to model populations with behavior. Behavior is almost always influenced by many factors simultaneously, mathematical modeling may therefore be a necessary tool to understand the events and the processes. Evolution has formed the sensory system so that the organism may respond adaptively to stimuli, and formed the emotion systems to be the major instruments in animals for evaluation of the sensory information, and choice of adequate behavior. The behavioral architecture of the emotion system may again have consequences for genetic diversity, and hence on population evolvability.

My main research interest is to understand what causes recruitment variability, particularly in pelagic fish such as herring in the Norwegian Sea, but I have also been working with sardinella in northwest Africa (Canary current) and sardine/anchovy in southeast Africa (Benguela current). I am mainly a field biologist but enjoy working together with scientists with other background such as modelers and physical oceanographers. I am also involved in stock assessment and advisory work on pelagic fish.

My PhD (physical oceanography) work focused on effects of turbulence on the ecosystem and mixing processes in fjords and coastal waters, with special emphasis on turbulence measurements and analysis. In the last decade the field of interest has expanded to involve ecosystem functioning and interactions in the Nordic and Barents Seas, with special focus on couplings between climate and fish, and effects of climate change on the ecosystem.

My main field of research is modeling of spatial distribution, population dynamics and behavior of plankton species. I also take a special interest in understanding how these species are linked to organisms at other trophic levels to better understand how energy moves through food webs. I work mainly with individual-based models coupled to physical ocean circulation models, but I also spend time analyzing field data to enable a sound scientific ground truthing of my models.

I am a PhD-student in the RETROSPECT project with focus on biophysical modelling in Lofoten and Vesterålen. My research interests lies both in oceanography and meteorology, and I focus therefore on subjects related to physical processes in the boundary layer between the ocean and atmosphere. I will contribute to the cross-disciplinary effort in coupling ocean reanalysis, in-situ field data and biophysical models for planktonic drift.

I have focused my research on physical-biological interactions in marine ecosystems, particularly on processes linked to zoo- and ichthyoplankton dynamics. This work has further lead my research to fish recruitment studies and effects of climate variability and climate change on marine ecosystems. I have been working in ecosystems from high-latitude to low-latitude and eastern boundary upwelling ecosystems.

My main research interest is recruitment mechanisms and stock dynamics of Norwegian spring spawning herring. Historical data indicates that variation in recruitment is one of the main driving forces for the dynamics of this potentially large herring stock. It has had great variations in abundance throughout the (more than) 100 years the dynamics of this stock have been known. These questions have been central questions for researchers for decades and Hjort himself pointed at variations in recruitment to be central for variations in abundance of cod and herring.

My research interests focus on understanding changes in plankton community structure in response to environmental drivers. I am specifically interested in the mechanisms plankton employs to survive and proliferate, as well as incorporating these mechanisms into marine system simulations. In the future, I would like to work on connecting the interactions I have been studying to ecosystem health and resilience, and to explore links and feedbacks with higher trophic levels.

Main interest is within behavioural ecology of fish, with emphasis on fishes many trade-offs between foraging (growth) and predator evasion, and on how feeding behaviour and habitat choice is related to biological – (predation risk, food availability, life stage and sex) and physical variables (light, turbidity and oxygen) in their environment. Specialty: Field - and lab experimental studies of fish behaviour.

I work on coupling numerical models of the ocean and early stages of fish with the aim of understanding causes of recruitment variability. Also, I am involved in several projects studying the impact of human activities on key fish species, in particular petroleum activities in the Lofoten area. Previously I have been Research Group leader at the Bjerknes Centre for Climate Research, where I focused on regional downscaling of global climate models and the utilization in coupled physical –biological models.

My current research focus is on the impact of salmon farming on wild fish. My background is from behavioral ecology and recruitment biology of fishes where I have studied how behavior can affect functional relationships between the environment and survival of fish. My current research project revolves around studying how salmon lice from fish farms affect the marine survival of wild Atlantic salmon.

I am interested in structure- and diversity-generating mechanisms in the microbial part of the pelagic food web. Using idealized models with incorporated trade-offs between different life strategies, I study how control mechanisms may act similarly at different trophic levels, potentially giving the basis for a fractal-like organization of the pelagic food web.

As PhD-student I am part of the theoretical ecology group at the University of Bergen. My main focus is modelling the behavior of mesopelagic fish. In my work I want to address problems like changes in decision-making processes due to ageing and sexual selection as a decision-making process. Animal personalities will be focused on in both parts of the project.

My research interest is the interplay between evolutionary ecology and fishing as well as the consequences for fisheries management and resource economics. I use modelling and data analysis to study the role of density dependence, ecological and evolutionary effects of size-selective fishing, the economic value of biological attributes like fish size, and how they influence optimal management strategies.
