Differential Effects Of Canopy Trimming And Litter Deposition On Litterfall And Nutrient Dynamics In A Wet Subtropical Forest, Steven J. Hall, Whendee L. Silver, Grizelle González
Differential Effects Of Canopy Trimming And Litter Deposition On Litterfall And Nutrient Dynamics In A Wet Subtropical Forest, Steven J. Hall, Whendee L. Silver, Grizelle González
Steven J. Hall
Humid tropical forests have the highest rates of litterfall production globally, which fuels rapid nutrient recycling and high net ecosystem production. Severe storm events significantly alter patterns in litterfall mass and nutrient dynamics through a combination of canopy disturbance and litter deposition. In this study, we used a large-scale long-term manipulation experiment to explore the separate and combined effects of canopy trimming and litter deposition on litterfall rates and litter nutrient concentrations and content. The deposition of fine litter associated with the treatments was equivalent to more than two times the annual fine litterfall mass and nutrient content in control …

Tree Biomass And Carbon Storage In An Old Growth Forest In Southeastern Ohio, Adam Levesque, Christina Gall, Doug Fox, Karen Washburne, Sam Scherneck, Mark A. Gathany
The Research and Scholarship Symposium (2013-2019)
Recently there has been increased interest in determining the baseline levels of carbon storage in different ecosystems, because of greater concern over the issue of global climate change and increased atmospheric CO2 concentrations. With a better understanding of carbon sequestration in various ecosystems, we can use land in a more environment-conscious way, and negative human impacts on the earth can be decreased. Forest ecosystems are especially important, because they have an immense capacity to store carbon as compared to other ecosystems. The majority of carbon sequestered in forest ecosystems is contained in tree biomass, but there is also carbon contained …
Impacts Of Climate Change On Soil Microorganisms In Northern Hardwood Forests, Carley Jane Kratz
Impacts Of Climate Change On Soil Microorganisms In Northern Hardwood Forests, Carley Jane Kratz
Dissertations, Master's Theses and Master's Reports - Open
As global climate continues to change, it becomes more important to understand possible feedbacks from soils to the climate system. This dissertation focuses on soil microbial community responses to climate change factors in northern hardwood forests. Two soil warming experiments at Harvard Forest in Massachusetts, and a climate change manipulation experiment with both elevated temperature and increased moisture inputs in Michigan were sampled. The hyphal in-growth bag method was to understand how soil fungal biomass and respiration respond to climate change factors. Our results from phospholipid fatty acid (PLFA) analyses suggest that the hyphal in-growth bag method allows relatively pure …
