The release of organic matter (OM) by scleractinian corals represents a key physiological process that importantly contributes to coral reef ecosystem functioning, and is affected by inorganic nutrient availability. Although OM fluxes have been studied for several dominant reef taxa, no information is available for soft corals, one of the major benthic groups in tropical reef environments. Thus...

this study was conducted to determine the nutritive value of fresh and ensiled whole and partly stoned olive cake (oc) with or without molasses i.e., 0 and 50 gkg-1 on fresh basis. dry matter (dm), organic matter (om), crude protein (cp), neutral detergent fiber (ndf), acid detergent fiber (adf), lignin (sa), ether extract (ee), water soluble carbohydrates (wsc), and total phenols (tph) of all ...

Molar organic carbon to total nitrogen to organic phosphorus (OC:TN:OP) ratios are used in tandem with carbon isotopic values to constrain sources of organic matter (OM) to marine sediments in a tropical coastal embayment. Analysis of end-members specific to the study site indicates that the bulk OM pool cannot be modeled as a simple mixture of two end-members (terrestrial vs. marine OM), but r...

The elemental, molecular (lipid) and isotopic ( ) composition of organic matter in samples from the eutrophic lake, Rostherne Mere, U.K. were examined at high resolution in a single sediment core from a deep part of the lake. The distributions of lipids indicate an important contribution of allochthonous organic matter to the Rostherne sediments. However, increases in concentrations of unsatura...

Sewage and sludge samples were collected from rural areas of Vellore district. The metals like Cu, Zn, Cd, Pb, Fe, Ca and Mg were determined by Inductively coupled plasma atomic emission spectrophotometry (ICP-AES). For this determination HCl - HNO3 and 4N HNO3 extracts were used. The total organic carbon (TOC), chemical oxygen demand (COD) and organic matter (OM) have also been determined to e...

When building soil organic matter (SOM) contents in agricultural production systems, stabilization of both pre-existing as well as added C is important. A laboratory mineralization experiment was conducted over 374 days to evaluate the effect of pre-existing SOM on soil C mineralization after addition of organic matter (OM) using sugar cane. The SOM gradient used here stretched from 21 to 106 g...

We present elemental, lipid biomarker and, in the supplement, compound-specific isotope (δC, δH) data for soils and leaf litter collected in the catchment of Lake Ohrid (Albania, Macedonia), as well as macrophytes, particulate organic matter and sediments from the lake itself. Lake Ohrid provides an outstanding archive of continental environmental change of at least 1.2 million years and the pu...

Background Microorganisms govern important ecosystems processes, in particular the degradation of organic matter (OM). However, microorganisms are rarely considered in efforts to monitor ecosystem health and functioning. Evidence suggests that environmental perturbations can adversely affect microbial communities and their ability to use available substrates. However, whether impacted microbial...
