Soil microbial biomass and enzyme activities have an important influence on nutrient cycling. The temporal variation in soil microbial biomass C, N, and enzyme activities during the growing season were determined under three different alpine grasslands in Northern Tibet. The results showed that soil microbial biomass C, and N contents and enzyme activities of the alpine meadow (AM) and the alpi...
GUO HC, WANG WB, LUO XH & WU XP. 2015. Characteristics of rhizosphere and bulk soil microbial communities in rubber plantations in Hainan Island, China. Phospholipid fatty acid analysis was used to investigate spatial variations in microbial communities of rhizosphere and bulk soil in rubber plantations in Hainan Island. Rhizosphere and bulk soil were collected from immature and mature rubber t...
Soil CO2 flux was measured across 947 plots at 7 experimental grassland sites at the Cedar Creek Natural History Area in order to determine the relationships between soil CO2 flux and environmental factors, living plant biomass, and soil C and N. Soil CO2 flux increased as the day progressed, and was positively related to aboveground biomass, belowground biomass, and soil % C. However, most of ...
Despite the complexity of natural systems, heterogeneity caused by the fragmentation of habitats has seldom been considered when investigating ecosystem processes. Empirical approaches that have included the influence of heterogeneity tend to be biased towards terrestrial habitats; yet marine systems offer opportunities by virtue of their relative ease of manipulation, rapid response times and ...
Natural disturbances along with human interference make the tropical estuaries amongst the most disturbed areas globally. In spite of this, information on the seasonal variability of macrofauna from tropical estuaries is few. Temporal variability of macrofaunal community from Mormugao Bay, Zuari estuary, on the west coast of India was examined from 2003 to 2004 at seven stations. Environmental ...
Title of Document: NAKED GOBIES (GOBIOSOMA BOSC) AS INDICATORS OF OYSTER REEF RESTORATION SUCCESS Terra M Lederhouse, M.S., 2009 Directed By: Dr. Kennedy T. Paynter, Director, Marine and Estuarine Environmental Sciences Naked gobies (Gobiosoma bosc) are the most abundant resident fish on oyster reefs in the Chesapeake Bay and serve as a critical trophic link between the benthic and pelagic comm...
Soil microbial biomass is a key determinant of carbon dynamics in the soil. Several studies have shown that soil microbial biomass significantly increases with plant species diversity, but it remains unclear whether plant species diversity can also stabilize soil microbial biomass in a changing environment. This question is particularly relevant as many global environmental change (GEC) factors...

Forest management, including selection of appropriate tree species to mitigate climate change and sustain biodiversity, requires a better understanding factors that affect the composition soil fauna communities. These communities are an integral part ecosystem play essential role in forest functioning related carbon nitrogen cycling. Here, by performing field study across six common gardens Den...
