Ulrich Sommer (biologist)

from Wikipedia, the free encyclopedia

Ulrich Sommer (born September 1, 1952 in Vienna ) is an Austrian ecologist who is best known for his work in the field of limnology and marine biology .

biography

Ulrich Sommer began his scientific career as a research assistant at the Institute for Plant Physiology at the University of Vienna , where he received his doctorate in 1977 and worked until 1979. From 1979 to 1985 he worked as an assistant professor at the Limnological Institute at the University of Konstanz , where he received his habilitation in 1985 .

In 1985 he moved to the Max Planck Institute for Limnology in Plön , where he worked in the Ecophysiology group with Winfried Lampert until 1991. In 1991, Sommer was appointed to the chair for microbiology of geological processes at the Institute for Chemistry and Biology of the Sea at the University of Oldenburg . called. In 1991 he finally went to the Leibniz Institute for Marine Sciences (today Helmholtz Center for Ocean Research Kiel ), Experimental Ecology I (food webs), at the University of Kiel as Professor of Biological Oceanography .

research

Ulrich Sommer devoted his research to the ecology in plankton and in the soil communities and investigated the interspecific interrelationships of species, especially competition and nutrition, with the influence of species dominance, coexistence and species diversity playing a central role. In the area of mesozooplankton , he analyzes the trophic levels depending on the size and nutrient content of the phytoplankton . He is also the coordinator of the DFG project AQUASHIFT to investigate the effects of climate change on aquatic ecosystems, specifically examining the influence of warmer winters on the spring development of plankton.
