Linking Carbon Dynamics in Stream Ecosystems to Dissolved Organic Matter Quality
… form of CO2 from groundwater, streams receive organic matter from aquatic and terrestrial origins which is partly mineralized to inorganic nutrients and CO2. Future predictions suggest enhanced input of terrestrial organic matter into streams. As such, surrounding land use may highly influence …

Plant species effects on soil organic matter turnover and nutrient release in forests and grasslands
… of species on soil C and N dynamics; changes in organic matter quality and changes in soil aggregation. For several forest ecosystems, litter lignin:N ratio correlated negatively (non-linear) with net N mineralization, but the relationship did not apply to grass species. Climatic factors …

Ecological assessments of Pseudomonas communities in pastoral soils: implications for disease suppression and sustainable production in agricultural grasslands
… ecosystem services such as ensuring water quality and soil carbon storage. An increasing proportion of grasslands are being used to support grazing livestock, with agricultural grasslands covering over 25% of the Earth’s ice-free land surface. Despite the increasing economic value of …

Integrated approach to solving reservoir problems and evaluations using Sequence Stratigraphy, Geological Structures and Diagenesis in Orange Basin, South Africa"
… integrated approach to evaluate reservoir rock quality and source rock potential is becoming increasingly important in petroleum geology. This approach was employed to unravel the reason for variable reservoir quality of sandstones and evaluation of source rock potential of shale intervals of …

Effect of heavy metals on salt march biota
… of total hydrolysable amino acids (THAA) in the organic material analyzed after the third growing season as measure for organic matter quality and thus metabolic processes were similar in cores of all treatments and thus indicated no significant biotic environmental differences that might have …

Palynology, palynofacies and hydrocarbon potential of the Cretaceous rocks of northern Egypt
… represented by deposition of<br/>a few organic-rich marine shale intercalations that are interpreted as shallow<br/>marginal marine in origin. These environmental fluctuations are related to global<br/>sea level fluctuations and global tectonic processes, such as the breakup …

Import and decomposition of dissolved organic carbon in pre-dams of drinking water reservoirs
Dissolved organic carbon (DOC) depicts a key component in the aquatic carbon cycle as well as for drinking water production from surface waters. DOC concentrations increased in water bodies of the northern hemisphere in the last decades, posing ecological consequences and water quality problems. …
