Master project title:

Effects of terrestrial inputs on community composition of softbottom benthos in Isfjorden, Svalbard.

Master project description:

Benthic community composition is determined by a variety of abiotic factors, which vary on regional and local scales. In Svalbard fjords, benthic communities are subject to a range of environmental conditions, ranging from disturbed inner basins where glacial melt water brings freshwater and heavy loads of sediments, to deep saline waters in the open fjord. Increased terrestrial run-off from a warming Arctic landscape is delivering freshwater and inorganic sediments (and associated nutrients and organic matter) to coastal areas, with implications for local benthic community structure and functioning. This MSc project focuses on benthic community distribution in Isfjord in relation to physical parameters of the water column and sediments. Soft-bottom macrofauna samples will be collected using a Van-Veen grab along inner to outer fjord transects in Billefjord, Tempelfjord and Adventfjord in the Isfjord fjordsystem and community composition will be analyzed in relation to abiotic factors.ThisMSc project is a part of the TerrACE project (NFR project from 2017–2021; PI: Amanda Poste, NIVA).

Research interests:

  • Evolutionary and Seasonal Ecology
  • Main aim: understand why we observe variation in life histories and behavior and how this variation influences interactions, populations and ecosystems.

I work in highly seasonal environments and study the scheduling of annual events and the trade-offs involved. Key traits: reproduction, energy storage, dormancy and migrations. What is the scope of state-dependent responses? What is the role of phenotypic plasticity versus evolution? Most of my work is on the ecology and evolution of birds, fish and zooplankton using mathematical models and statistical analyses of data. An important component of my work is to use the insights we gain to understand and predict how organisms respond to environmental variability and change, with pollution, harvesting and climate change as central stressors.

With my research, I would like to provide new knowledge on how anthropogenic activity in Arctic regions affect the fitness and survival of key species in this pristine marine ecosystem. Hence, my research combines the study of basic ecological traits of marine organisms with the performance of exposure experiments in order to evaluate the threat of contamination for marine organisms in the Arctic. As key species in the Arctic marine ecosystem, polar cod has been the focal species of my research during the last years. In my PhD thesis, I investigated the biological effects of crude oil on essential physiological processes related to the fitness of polar cod. This work was part of the project POLARISATION (Norwegian Research Council # 214184, http://site.uit.no/polarisation/) and supervised by Jasmine Nahrgang.

PhD project title:

Microbial carbon cycling in the seasonal ice zone: linking observations and experiments to dynamic modelling

Project description:

The carbon cycle in the seasonal ice zone is highly dynamic over the year and and in a changing climate. Light limitations in the polar night, ice formation and melt, and nutrient limitations are some of these dynamic factors. Dynamic ecosystem models are still neglecting these dynamics and the physiological mechanisms of algae and bacteria to deal with it. The aim of my PhD is to study Three important processes in the microbial carbon cycle in the seasonal ice zone which are poorly characterized in current ecosystem models; 1) heterotrophic carbon uptake in microalgae as response to light and nutrient limitation, also as potential survial strategy in the polar night; 2) The role of bacteria as competitors or commensalists via nutrient recycling under different light and nutrient conditions; 3) The role of tidewater outlet glaciers on microbial communities and their function in the ecosystem.  I will quantify the role of the Three processes in the carbon cycle and show their importance in dynamic ecosystem models. The results will help to understand the importance of key processs and to improve predictions on the effect of climate change on the  carbon cycle.
