6. 25. Shifts within the carbon cycle in response to the absence of keystone herbivore Ovibos moschatus in a high arctic mire

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Joel White; [2017]
   Keywords : vegetation; carbon; wetland.; methane; Arctic; Physical Geography Ecosystem Science; herbivory; Earth and Environmental Sciences;

   Abstract : Tundra ecosystems are generally recognized as globally important carbon sinks, yet the knowledge on threats to such ecosystems is narrow. Climate change is predicted to reduce the number of muskox (Ovibos moschatus) in the arctic, it is therefore essential to understand the effect herbivores induce on the arctic ecosystem. READ MORE
