IMG_4379My name is Arne Jacobs and I am an evolutionary biologist with interests in rapid evolution, adaptation genomics and gene regulatory evolution in natural systems, 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 phenotypic, functional genomic and population genomic approaches to  better understand the proximate and ultimate mechanisms underlying rapid adaptation and phenotypic evolution. I have great interest in understanding the developmental and molecular mechanisms underlying adaptive phenotypic changes. I think that integrating diverse approaches will allow one to gain a more complete understanding of how the fascinating biodiversity surrounding us has evolved. Ultimately, this knowledge will be key to preserving and protecting this diversity.

I study a wide range of species, ranging from local adaptation to steep thermal clines in Atlantic silversides, to adaptation to urban environments in great tits, the population and functional genomics of rapid and parallel evolution in salmonids, and most recently the genomic and functional mechanisms underlying the repeated loss of parasitism in lamprey.
