Overview

Ulf Karsten is affiliated with the University of Rostock in Germany. Their research primarily focuses on environmental sciences, earth and planetary sciences, and agricultural and biological sciences. Within these broad fields, they have contributed extensively to subfields including ecology, evolution, behavior and systematics, oceanography, ecology, environmental chemistry, as well as renewable energy, sustainability, and the environment.

The main topics of Karsten's work revolve around biocrusts and microbial ecology, marine and coastal plant biology, aquatic ecosystems and phytoplankton dynamics, lichen and fungal ecology, marine and coastal ecosystems, microbial community ecology and physiology, and algal biology with an emphasis on biofuel production.

Frequent coauthors in their collaborations include Karin Glaser, Tatiana Mikhailyuk, Angelika Graiff, Inka Bartsch, and Ekaterina Pushkareva.

Karsten has published numerous papers, with some recent notable examples being:

  • Biodiversity of Algae and Cyanobacteria in Biological Soil Crusts Collected Along a Climatic Gradient in Chile Using an Integrative Approach (2020, Microorganisms)
  • Impacts of combined temperature and salinity stress on the endemic Arctic brown seaweed Laminaria solidungula J. Agardh (2020, Polar Biology)
  • Five decades of terrestrial and freshwater research at Ny-Ålesund, Svalbard (2022, Polar Research)
  • Klebsormidin A and B, Two New UV-Sunscreen Compounds in Green Microalgal Interfilum and Klebsormidium Species (Streptophyta) From Terrestrial Habitats (2020, Frontiers in Microbiology)
  • Summer Heatwave Impacts on the European Kelp Saccharina latissima Across Its Latitudinal Distribution Gradient (2021, Frontiers in Marine Science)
