my name is Arne Jacobs and I am an evolutionary biologist with interests in rapid evolution, population genetics, adaptation genomics and gene regulatory evolution in natural systems, as well as developmental and morphological evolution, particularly in fishes. I am currently a Postdoc in the lab of Nina O. Therkildsen in the Department of Natural Resources at Cornell University.
My research focuses on integrating eco-morphological, functional genomic and population genomic approaches to understand rapid & parallel phenotypic adaptation. In the Therkildsen Lab, I am working on the genomic mechanisms of local adaptation under gene flow in the Atlantic silverside, a small estuarine fish that is distributed along a steep climatic gradient along the North American Atlantic coast. Previously, I focused on the extraordinary diversifications of salmonid fishes in postglacial lakes. Therein, I focused on studying extensive replicated diversifications in one of the most diverse vertebrate species, Arctic charr (Salvelinus alpinus); examining ecological, phenotypic and genomic patterns and processes of contemporary trophic divergences in European whitefish (Coregonus lavaretus); and genomic patterns of life history evolution in the enigmatic ferox trout, a brown trout (Salmo trutta) ecotype.
I also have a great interest in understanding the genomic architecture underlying complex traits and gene regulatory evolution across different evolutionary scales and under different demographic scenarios.
