Integrating omics to characterize eco‐physiological adaptations: How moose diet and metabolism differ across biogeographic zones
1. With accelerated land conversion and global heating at northern latitudes, it becomes crucial to understand, how life histories of animals in extreme environments adapt to these changes. Animals may either adapt by adjusting foraging behavior or through physiological responses, including adjustin...
