The Effects of 40% Throughfall Reduction on Soil Respiration in a Longleaf Pine Plantation

Blackstock, Jake (2018-08-24)

Longleaf pine (Pinus palustris) forests can serve as disturbance-resistant, long-term carbon sinks, but net ecosystem productivity of longleaf pine forests has been shown to be sensitive to drought. Soil respiration (Rs) ...

The Effects of Fertilization and Four Years of Throughfall Reduction on Leaf Physiology of Loblolly Pine (Pinus taeda L.)

Pell, Charles (2015-12-10)

Loblolly pine (Pinus taeda L.) is the most widely planted pine species in the southeastern United States. Increased frequency of drought associated with projected climate change may negatively impact loblolly pine productivity. ...

Fertilization Effects on Water Use of 8-year-old Loblolly Pine (Pinus taeda L.) Vary with Throughfall Treatment

Bartkowiak, Stanley, IV (2015-01-07)

Loblolly pine (Pinus taeda L.) plantations in the southern U.S. generate more timber than any other country in the world and therefore reductions in net primary productivity associated with climate variability may have ...

Global fire activities and their impacts on the terrestrial carbon budget in context of multiple environmental changes

Yang, Jia (2015-07-28)

As one major disturbance in the earth system, fires modified vegetation structure and functioning, atmospheric composition, and climate conditions at both regional and global scales. Under the impacts of substantial changes ...

Impacts of Drought and 40% Throughfall Reduction on Water Relations of a Longleaf Pine Stand

Ramirez, Michael (2018-11-05)

Projections of increased frequency and severity of climatic- induced drought have raised concerns about the health, productivity and composition of forests in the southeastern United States. Longleaf pine (Pinus palustris ...

Relationships between forest structure and soil CO2 efflux in 50-year-old longleaf pine

Whitaker, William Bennett (2009-12-17)

Global climate change and the accumulation of the greenhouse gas, carbon dioxide (CO2), in the atmosphere, may be mitigated by the proper management of soils and forests through carbon (C) sequestration. Longleaf pine ...

Riparian Woody Plant Diversity, Composition, and Structure across an Urban-Rural Land Use Gradient in the Piedmont of Georgia, US

Burton, Michele (2006-12-15)

Riparian forests are increasingly threatened by urban expansion and land use change worldwide. Understanding the impacts of urbanization on riparian forests is critical because riparian areas provide a variety of important ...

Temporal and spatial variation in longleaf pine soil respiration and its heterotrophic and autotrophic components

ArchMiller, Althea (2015-05-07)

Soil respiration (Rs) is the sum efflux of CO2 from soil derived from the metabolic activity of autotrophs and heterotrophs in the litter layer, root-affected soil (rhizosphere), and bulk soil. Soil respiration exhibits ...

Turkey Oak (Quercus laevis W.) Seedlings Experience Primarily Competitive Pressures, not Facilitation, from the Overstory in a Longleaf Pine (Pinus palustris M.) Ecosystem

Reynolds, Sean (2020-07-09)

At a site dominated by longleaf pine (Pinus palustris Mill.) in southwestern Georgia, silvicultural plans designed to encourage ecosystem-level tolerance to climate changes - namely increased water stress - are under ...
