Inputs of terrestrial high molecular weight

A taxonomic study of blue-green algae based on morphological, physiological and molecular characterization in Yazd province terrestrial ecosystems (Iran)

Based on the limited resources available to algal flora in Yazd province in the center of Iran, cultivation, purification and identification of soil algae from seven sites was performed in summer 2013. The soil samples were processed for analysis of Cd, Pb contents. The present paper attempts to analyze survey of soil blue-green algal identification in different types of stations, using morphol...

Solubility Prediction of High Molecular Weight n-Paraffins in Supercritical Carbon Dioxide

Solubility of high molecular weight n-paraffins in supercritical carbon dioxide has been a matter of interest to many researchers. However, not sufficient solubility experimental data are available although the methods by which the experimental data are obtained have many varieties. Utilizing cubic equations of state is an effective method for solubility prediction of n-paraffins in supercr...

The importance of terrestrial organic carbon inputs on Kara Sea shelves as revealed by n - alkanes , OC and d 13 C values

Organic carbon (OC) and n-alkanes were investigated in the suspended matter (SM) and sur®cial sediments of the Arctic Ob and Yenisei Rivers and the adjacent Kara Sea. Organic nitrogen and dC values were determined as additional parameters in the sediments. OC and n-alkane concentrations were highly variable in space. This variability was interpreted as the result of a complex sedimentation patt...

Mass Flux Calculations Show Strong Allochthonous Support of Freshwater Zooplankton Production Is Unlikely

Many studies have concluded terrestrial carbon inputs contribute 20-70% of the carbon supporting zooplankton and fish production in lakes. Conversely, it is also known that terrestrial carbon inputs are of very low nutritional quality and phytoplankton are strongly preferentially utilized by zooplankton. Because of its low quality, substantial terrestrial support of zooplankton production in la...
