More about the project
These substances are produced by bacteria and phytoplankton and are transferred by zooplankton to fish and birds. The overall aim of this project is to understand the factors regulating the transfer between trophic levels and to explore possible links between these processes and deficiency syndromes in top predators.
We perform both field samplings and experimental studies. Pigments and vitamins are quantified with high-precision liquid chromatography (HPLC).
This project covers both field investigations of spatial variations in pigments and vitamins, as well as laboratory experiments addressing mechanistic connections and interactions. I will:
- Incorporate the production and transfer of pigments and vitamins into nutritional food web ecology.
- Understand the underlying trade-offs and factors involved in regulating transfer of pigments and vitamins from phytoplankton via zooplankton to fish.
- Prime zooplankton for the production of nutritious aquaculture fish.
Predict changes in nutrition in the aquatic food web due to environmental threats such climate change.
- This is an overlooked research area and apart from interesting evolutionary questions
- I will be able to understand which factors that affect the transfer of important biomolecules and hence the underlying mechanisms creating deficiency syndromes in top predators.
The project is part of the research in the research group Zooplankton Ecology and in Linnaeus University Centre for Ecology and Evolution in Microbial model Systems (EEMiS).
