This book was released on 2015 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leaf litter decomposition is a critical component in nutrient cycling, ecosystem carbon budgets, and soil formation. Liming forest soil combats negative effects of acidic deposition: such as low soil pH, cation depletion, and aluminum mobilization. However, decomposition rates and nutrient dynamics following liming are poorly known. A litter bag study with limed and natural treatments was initiated in November 2012 at four sites within the Nantahala National Forest, NC, to examine the effects of liming on litter decay rates and nutrient dynamics in a northern hardwood forest affected by acid deposition. Litter bags consisted of mixed species leaf litter specific to each site and a single species reference litter collected offsite. Percent mass loss, decay rate, percent lignin and percent cellulose, CO2 efflux, carbon, nitrogen, calcium, magnesium, and aluminum were determined for litter bags collected every three months for one year. Liming had no major impact on decay rates of chestnut oak or mixed litter, although limed litter typically had slower decay rates. Percent lignin and cellulose remaining, two recalcitrant components of leaves, fluctuated over time in limed and natural litter. Liming significantly reduced CO2 efflux from chestnut oak and mixed species litter mostly in the first six months of the study. Liming reduced immobilization of nitrogen in chestnut oak and mixed litter throughout decomposition and significantly decreased the carbon concentration. Calcium and magnesium concentration of limed litter was significantly greater than natural litter, while aluminum concentration was not affected by lime. This study suggests that applying lime to areas affected by acid rain may alter nutrient dynamics by impeding microbial decomposition of litter, but causes insignificant change to mass loss and associated decay rates. Future work should focus on carbon and nitrogen dynamics in limed versus natural leaf litter as well as different application rates of lime for a period that extends beyond one year.

Download or read book Leaf Litter Decomposition in Restored Stream wetland Complexes Compared to Forested Headwater Streams written by Kelly Anne Love and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leaf litter breakdown rates are frequently employed as functional indicators of health in both terrestrial and aquatic ecosystems. I deployed coarse mesh litter bags to measure organic matter processing during summer in three forested stream channels and three stream-wetland complexes constructed as part of a floodplain reconnection restoration project in western Pennsylvania. I predicted that in stream-wetland complexes, leaf litter breakdown would occur at a faster rate based on warmer temperatures, higher nutrient availability, and sunlight from the open canopy. Contrary to our expectations, litter decomposition over 56 days occurred at a slower rate at the stream-wetland complexes compared to the forested stream channels. Water chemistry, temperature, and the composition of macroinvertebrate communities in leaf litter bags differed between forested stream channels and stream-wetland complexes but was not correlated with leaf breakdown rates. I was unable to determine the role of Chl a on leaf litter breakdown in stream- wetland complexes due to the shade station not providing consistent shade. Macroinvertebrate communities differed significant between the forested unrestored sites and the stream-wetland complexes. The water chemistry indicated that the habitat was suitable for macroinvertebrates at all sites and nutrient availability was not significantly different.

Available in PDF, EPUB and Kindle. Book excerpt: The Fernow Watershed Acidification Study is a long-term, paired watershed acidification study. This book describes the responses to chronic N and S amendments by deciduous hardwood forests, one of the few studies to focus on hardwood forest ecosystems. Intensive monitoring of soil solution and stream chemistry, along with measurements of soil chemistry, and vegetation growth and chemistry, provide insights into the acidification process in forested watersheds.
