| Summary: | Arctic and alpine tundra ecosystems are experiencing accelerated warming compared to the global average, causing significant changes in plant productivity and the timing of life histories of tundra species, with cascading effects on trophic interactions and carbon cycling. However, the sparsity of long-term and spatially-varied observations hinders our understanding of how these dynamics may continue to change in a warming tundra biome. Specific knowledge gaps, often borne from limitations on year-round travel to tundra sites, hamper our ability to accurately predict the long-term trajectory of tundra phenology change, both above-ground and below-ground. In this PhD thesis, I use above- and below-ground ecological observations across spatial and temporal scales to resolve key questions about how heterogeneous tundra landscapes may respond to future warming and ecosystem change. My findings have implications for biome-scale carbon cycling and wildlife habitats. In Chapter 2, I used a geographically varied ... |
