Samuel Hylander carries out research in aquatic ecology studying food web transfer of micronutrients as well as adaptations among plankton to climate change and exposure to ultraviolet radiation or anoxic conditions.
Studies are carried out in both freshwater and marine systems in temperate and polar regions. Currently, he is focusing on the transfer of pigments (astaxanthin) and vitamins (B1, also called thiamin) in the Baltic Sea food web. These micronutrients are produced by bacteria and phytoplankton and are transferred via zooplankton to fish and birds. Several top predators are displaying symptoms of vitamin deficiency and low pigment levels, and the aim is to understand the basis of these environmental disturbances.
Other areas of interest include effects of anoxic conditions and a changing climate on the benthic-pelagic coupling and how zooplankton respond to ultraviolet radiation (UVR) by accumulating UVR-protective pigments and sunscreens (mycosporine-like amino acids).
Teaching
Samuel Hylander is program coordinator for the Biology Program at Linnaeus University. He is examiner and teacher in the Master´s program in Aquatic Ecology and also course coordinator and teacher in Freshwater ecology.
Commissions
Samuel Hylander is member of the steering committee (ledningsgrupp) of the Swedish Institute for the Marine Environment (Havsmiljöinstitutet) and is also contributing as member in the UNEP Environmental Effects Assessment Panel. This panel assesses the environmental effects of ozone depletion and its interactions with climate change providing advice to the parties of the Montreal Protocol.
