Jesper Bruun Mosbacher

Jesper Mosbacher has researched one of only few large herbivores in the arctic ecosystem, the muskox. The arctic ecosystems are changing rapidly with climate change. Given the central role of herbivores in ecosystem dynamics, understanding how muskoxen impact their environment as well as how they themselves are affected by the environment is crucial for our understanding of ecosystem-level responses to climate change. However, detailed knowledge on the impacts and population demographics of muskoxen are limited due to the remoteness and inaccessibility of this species in much of the Arctic. During his dissertation, Jesper Mosbacher used multiple different approaches, combining these various approaches, ranging from GPS collaring to novel and innovative chemical analyses of hair samples to examine the role of muskoxen in the arctic ecosystem, and how population demographics are impacted by their ambient environment.  

The new research findings has significantly contributed to the overall knowledge and understanding of muskoxen as a dominant key species in the Arctic, and is crucial for our understanding of the on-going and future environmental changes that will surface as the Arctic continues to warm.

The PhD degree was completed at the Department of Bioscience in Roskilde, Science and Technology, Aarhus University.
