Leaf litter decomposition and microarthropod abundance along an altitudinal gradient
Mass loss rates of three types of leaf litter were measured along an altitudinal gradient at the Coweeta Hydrologic Laboratory, Macon County, North Carolina. Litterbags containing air dried litter from Quercus prinus L., Liriodendron tulipifera L., and Rhododendron maximum L. were placed in five plots along the gradient and sampled monthly. Microarthropods were extracted and sorted, and litter ...
متن کاملThe interaction of plant genotype and herbivory decelerate leaf litter decomposition and alter nutrient dynamics
We examined how plant genetic variation and a common herbivore (the leaf-galling aphid, Pemphigus betae ) influenced leaf litter quality, decomposition, and nutrient dynamics in a dominant riparian tree (Populus spp.). Based on both observational studies and a herbivore exclusion experiment using trees of known genotype, we found four major patterns: 1) the quality of galled vs non-galled or ga...
متن کاملNo evidence for leaf-trait dissimilarity effects on litter decomposition, fungal decomposers, and nutrient dynamics.
Biodiversity and ecosystem-functioning theory suggest that litter mixtures composed of dissimilar leaf species can enhance decomposition due to species trait complementarity. Here we created a continuous gradient of litter chemistry trait variability within species mixtures to assess effects of litter dissimilarity on three related processes in a natural stream: litter decomposition, fungal bio...
متن کاملNutrient removal efficiency by floating macrophytes; Lemna minor and Azolla pinnata in a constructed wetland
The use of constructed wetlands for purifying pre-treated wastewater is a cost effective technology that has been found to be more appropriate for many developing countries. The technology is also environmentally friendly with the wetlands being habitats for many water birds and other aquatic organisms. This study assessed nutrient removal efficiency of two floating macrophytes (Lemna minor...
متن کاملHuman Influence Past and Present – Relationship of Nutrient and Hydrologic Conditions to Urban Wetland Macrophyte Distribution
Urban wetlands can provide valuable ecological services through filtration and moderation of non-point source pollutants. They provide habitat for wildlife, green space, and recreational opportunities for nearby human populations. We investigated an isolated section of an urban wetland in the Cleveland metropolitan area to determine the overall quality of the vegetation and to evaluate the site...
