Harvest Efficiency, Forage Trampling, and Litter Decomposition of Mob Grazing
… had on harvest efficiency, forage trampling, and litter decomposition. One experimental site was established in eastern South Dakota. Two separate experiments were conducted. The first experiment examined the effect of stocking density on utilization, harvest efficiency, and forage trampling. The …

The functional role of understorey herbs for litter decomposition in temperate forests
Litter decomposition is a vital process in forest carbon (C) and nutrient cycling, and it is known to be regulated by initial litter quality and climate variables. In forests, components like understorey vegetation are indispensable to ecosystem stability and ecological function. For example, the …

Soil community structure and litter decomposition under irrigated Eucalyptus Globulus in South Western Australia
… data on the composition of the soil and litter fauna and their contribution to litter decomposition under plantation systems (Adolphson, 2000). The Albany Effluent Irrigated Tree Farm provided an opportunity to research plantation (Eucalyptus globulus ) soil flora and fauna communities, …

The Effects of Ecological Restoration on Soil Microbial Enzyme Activities and Leaf Litter Decomposition
… restoration on soil enzyme activities and decomposition. The activities of five enzymes: phosphatase, ?-glucosidase, ?-N-acetylglucosadminidase (NAGase), phenol oxidase, and lignin-peroxidase were measured in both soils and on decomposing Quercus falcata leaf litter in unburned, burned, and …

Tree functional diversity affects litter decomposition and arthropod community composition in a tropical forest
… functional diversity, which in turn can modify decomposition processes and affect ecosystem carbon and nutrient cycling. Despite numerous studies on tropical litter decomposition, the links among plant- and invertebrate diversity and microbial function are far from clear. I investigated the …

Litter Decomposition in Created and Adjacent Forested Wetlands of the Coastal Plain of Virginia
Litter decomposition is a poorly understood function of constructed and natural forested wetlands. This study compared rates of litter mass loss, changes in litter morphology, and associated macroinvertebrate populations in constructed and natural non-tidal wetlands. Two sets of wetlands …

Effects of Western Spruce Budworm Herbivory on Forest Soils and Litter Decomposition in Central Washington
… Cascades and their herbivory could increase the decomposition rate of forest materials by adding essential nutrients and/or by increasing light and rainfall penetration to the forest floor by thinning the forest canopy during outbreaks. Budworm defoliation events are expected to increase in …

Effects of neonicotinoids and fungicides on soil invertebrate communities and litter decomposition within restored prairie
… composition, abundance, species diversity, and litter decomposition across restored prairie plots treated with a neonicotinoid (clothianidin) and a fungicide (Captan). Soil invertebrate communities in plots treated with a combination of neonicotinoids and fungicides were nearly half as dense as …

Evaluation of Mob Grazing and its Impacts on Soil Moisture and Temperature and Litter Decomposition in South Dakota
… has on ecosystem processes, we observed litter decomposition, soil moisture, and soil temperature in mob grazed areas compared to the extremes of the spectrum: Ungrazed and Bare ground plots. This study was conducted at four producer locations in South Dakota, near Quinn, Chamberlain, …

From litter decomposition to soil organic matter formation: using stable isotopes to determine the fate of carbon and nitrogen
Litter decomposition releases the energy and nutrients fixed during photosynthesis into the atmosphere and soil. In the soil, carbon and nitrogen from the litter can be stabilized in soil organic matter pools, which globally represent large pools of both carbon (C) and nitrogen (N). Soil organic …

The influence of current year fire on leaf litter decomposition rates and microbial enzyme activity in forests undergoing ecological restoration
… and has the potential to change rates of decomposition and nutrient cycling through changes in environmental conditions or leaf litter composition. Restoration projects to reduce the effects of mesophication include thinning the canopy to remove mesophytic species and prescribed burn …

Soil Microbial Diversity and Litter Decomposition Increase with Time Since Land Use Disturbance in Tropical Montane Forests of Malaysian Borneo
… and disrupt carbon cycling through shifts in litter decomposition. Direct links between microbial diversity and soil properties such as pH are well established; however, the indirect impacts of logging and forest conversion on microbial diversity and litter decomposition are poorly understood. …

Drivers of leaf litter decomposition along a successional gradient in the upland Andes: linking environment, functional traits, biodiversity, and carbon cycling
Comprender los mecanismos que controlan la descomposición de la hojarasca es clave para explicar la dinámica del carbono en ecosistemas tropicales de montaña. Esta tesis doctoral tuvo como objetivo identificar los principales factores bióticos y abióticos que determinan la descomposición de la …

The Role and Contribution of Saprotrophic Fungi during Standing Litter Decomposition of Two Perennial Grass Species, <i>Schizachyrium scoparium</i> and <i>Schizachyrium tenerum</i>
… enzymatically degrade, and assimilate plant litter carbon and nutrients in amounts sufficient to bring about the decomposition of plant litter. Here, I estimated the biomass and production of fungi and microbial respiration associated with decaying <em>Schizachyrium scoparium</em> and …

Effect of a Water Treatment BMP on Nutrient Spiraling and Leaf Litter Breakdown in an Urban Stream
… of this BMP on nutrient spiraling and leaf litter decomposition in a 2 km stretch of Weracoba Creek. I hypothesized the BMP would (1) reduce leaf mass loss over time and (2) interfere with nutrient concentrations and uptake lengths. I characterized leaf litter decomposition using tulip tree …

Biogeochemical effects of an invasive grass across a land-use gradient: linking alterations of nitrogen cycling to depleted soil carbon pools
… impacts of M. vimineum on soil C and litter decomposition, with more soil C loss and greater litter decomposition at sites with low N availability. However, I found that this effect was contingent on M. vimineum biomass such that the largest reductions of soil C, but smallest effects …

Evaluation of Ecological Function of Urban Riparian and Stream Systems: Guiding Ecological Restoration in Austin, Texas, USA
… function of a group of urban streams, leaf-litter decomposition was used as an integrated metric for assessing anthropogenic impacts. I measured leaf-litter decomposition rate with two species, Texas Red Oak (Quercus texana) and American Sycamore (Platanus occidentalis), as a response …
