Carbon Dioxide Emissions From Deadwood In Forests Of The Northeastern United States, Zoe Read
Carbon Dioxide Emissions From Deadwood In Forests Of The Northeastern United States, Zoe Read
Electronic Theses and Dissertations
As the climate changes, understanding the sources and sinks of greenhouse gases such as carbon dioxide (CO2) is increasingly important. However, several components of the carbon cycle within forests remain poorly understood. For example, knowledge gaps exist in our understanding of CO2 emissions from coarse woody material (CWM; logs and stumps), including how emissions change over time, how they are influenced by environmental variables, and how they compare to soil and ecosystem-level CO2 emissions.
To fill these knowledge gaps, we examined CO2 emissions from CWM at three sites. We sampled 18 red spruce (Picea …
A Sky Island Perspective: New England Alpine Plant Distributions Across The Region, Andrea Tirrell
A Sky Island Perspective: New England Alpine Plant Distributions Across The Region, Andrea Tirrell
Electronic Theses and Dissertations
Alpine ecosystems around the globe are at risk due to climate change, human disturbance, and habitat loss. New England alpine zones are small and fragmented, which could make them vulnerable to global change. However, the persistence of tundra relics throughout the Holocene suggests the persistence of these communities in microclimate refugia. Assessing the near-term vulnerability of alpine plant communities is challenged by a lack of standardized, repeat surveys and long-term monitoring data, which presents a challenge for the many agencies monitoring New England’s alpine zones. Island biogeography theory predicts that alpine species richness is a function of area, but this …
Assessing The Long-Term Effects Of Natural Disturbance-Based Silvicultural On The Avian Assemblage At The Acadian Forest Ecosystem Research Program, Carl Pohlman
Electronic Theses and Dissertations
Active forest management alters the resources available to forest-obligate species. Large-scale intensive management practices where timber production is the primary objective can lead to notable ecological changes in forest ecosystems. A key concept of ecological forestry is to design forest management activities to emulate natural disturbance regimes as a way to maintain the ecological integrity of forests. The Acadian Forest Ecosystem Research Program (AFERP) was undertaken as an experimental demonstration of management reflective of the region’s disturbance regime, which typically produces small canopy gaps. AFERP includes nine research areas assigned to three silvicultural treatments: unharvested control, small gap (expanding-group selection …
