PhD project title:

Spatial and temporal shifts in Arctic fjord biodiversity caused by climate changes.

PhD project description:

Climate change in Arctic coastal systems leads to declining sea ice and sea-terminating glaciers, and these changes are expected to modify biodiversity and ecosystem functioning in the littoral fjord areas. In addition, influx of Atlantic water and invasive species, which may compete with and displace Arctic species, may change community composition and spatial distribution. As part of the EU project FACE-IT, my PhD aims to study these changes in the cryosphere of littoral Arctic fjord areas and link them to the spatial distribution of biodiversity and abundance, with a focus on littoral fish. In this project we use sustainable, non-invasive monitoring tools and cutting-edge technology, by the use of an Unmanned Surface Vehicle (USV) with an autonomous echosounder system, oceanographic sensors and underwater camera systems. This study contributes to a better understanding of the links between marine biodiversity, land influx and changes in the cryosphere, addressing the ongoing climate change mechanisms in the High Arctic land to sea interactions.

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.

PhD project title:

Benthic Metazoan Meiofauna of the Barents Sea – Ecology, Systematics and Evolution.

PhD project description:

Benthic meiofauna are a diverse guild of tiny animals which inhabit the sediments of the Earth’s ocean floors. Many meiofaunal groups have evolved remarkable adaptations to cope with life between the grains, such as elaborate adhesive gland systems or the ability to thrive in low-oxygen environments. Typically, the animals range between 30-500 μm in length, and many taxa are elongated and blind. Meiofauna are a scientifically neglected group, and taxonomic discoveries on the phylum level have happened several times within recent memory; for instance, Loricifera was described from shelly gravels of the North Sea in 1983, and Micrognathozoa from Greenlandic sediments in 1996. In few places are meiofaunal communities more poorly understood than in the freezing waters of the Arctic Ocean, where they now face a mounting threat from climate change and atlantification. Improving the knowledge status of the diversity, systematics, ecology, and evolutionary adaptations of Arctic meiofauna is therefore an urgent matter, which my project aims to address.

PhD project title:

Evolution of Surface Ocean hydrography in the Nordic Seas during warmer-than-present time periods: proxy development and applications.

PhD project description:

In my project, I aim to develop methods for reconstructing surface ocean conditions and ocean-cryosphere interactions during past warmer-than-present periods in the Arctic. To do so, I am culturing the polar, planktic foraminifera (single-celled protist) Neogloboquadrina pachyderma under independently variable conditions and investigating the relationships between ocean conditions (salinity, temperature, pH, etc.) and the chemical composition of the foraminifera shells. I will then apply these methods (and others) to sedimentary records from the Arctic Ocean and Nordic Seas to reconstruct past conditions of these regions. A secondary objective is to observe the foraminifera in the laboratory, including their tolerance and response to changing water conditions such as increased temperature and lower pH, which has implications for the ongoing climate change. If successful, will the new methods provide a powerful toolbox for reconstructing surface ocean hydrography and circulation at high latitudes.
