Effects of Misgurnus anguillicaudatus and Cipangopaludina cathayensis on Pollutant Removal and Microbial Community in Constructed Wetlands
Aquatic animals play an important role in the energy flow and matter cycling in the wetland ecosystem. However, little is known about their effects on pollutant removal performance and microbial community in constructed wetlands. This work presents an initial attempt to investigate the effects of Misgurnus anguillicaudatus (loach) and Cipangopaludina cathayensis (snail) on nutrient removal perf...
متن کاملHow body size mediates the role of animals in nutrient cycling in aquatic ecosystems
Introduction Aquatic ecosystems have been fertile ground for understanding the extent to which animals can alter nutrient cycling. Although animals have been included in ecosystem models for years (for example, Teal, 1962), it is only more recently that investigators have looked at animals, either as individuals, single species, or assemblages, as agents regulating nutrient cycling (Kitchell et...
متن کاملEcological Perspectives on Microbes Involved in N-Cycling
Nitrogen (N) cycles have been directly linked to the functional stability of ecosystems because N is an essential element for life. Furthermore, the supply of N to organisms regulates primary productivity in many natural ecosystems. Microbial communities have been shown to significantly contribute to N cycles because many N-cycling processes are microbially mediated. Only particular groups of m...
متن کاملMechanisms of plant species impacts on ecosystem nitrogen cycling
J. M. H. Knops,* K. L. Bradley and D. A. Wedin School of Biological Sciences, School of Natural Resource Sciences, University of Nebraska, 348 Manter Hall, Lincoln, NE 68588, USA. *Correspondence: E-mail: [email protected] Abstract Plant species are hypothesized to impact ecosystem nitrogen cycling in two distinctly different ways. First, differences in nitrogen use efficiency can lead to positiv...
متن کاملMetagenomic reconstruction of nitrogen cycling pathways in a CO2-enriched grassland ecosystem
The nitrogen (N) cycle is a collection of important biogeochemical pathways mediated by microbial communities and is an important constraint in response to elevated CO2 in many terrestrial ecosystems. Previous studies attempting to relate soil N cycling to microbial genetic data mainly focused on a few gene families by PCR, protein assays and functional gene arrays, leaving the taxonomic and fu...
