Phytoplankton biomarkers were analyzed using suspended particles collected from the northern South China Sea (SCS) during the summer cruise of 2008, with the goal of understanding the algal community structure and biomass distribution pattern in the summer season. The results indicated that the distribution of algal biomarkers in surface water of SCS was impacted and constrained by the local hydrological...
Nowadays, even though countries take measures to control the population, it is reported that the total number of global population has reached 7billion. In 21st century, the human society is still faced with the problems about the unprecedented consumption of material wealth and the unprecedented increase in population [1]. So the researchers should study the dynamic changes of resources and population...
Phospholipid fatty acid (PLFA) can be used as biological marker of microbial biomass and community structure. In this study PLFA analysis was used on soil microbial diversity with pyrene added. The results showed that in the short term, low concentrations of pyrene had no significant effect on Bac-PLFA and Fun-PLFA, while high concentration pyrene showed inhibition effect. It also revealed that every...
Pot experiments were conducted to study the effects of 8 fertilizers (NH4Cl, NH4NO3, Ca(NO3)2, CO(NH2)2, Ca(H2PO4)2, KH2PO4, K2SO4 and KCl) on Ni uptake and distribution by rice. The results indicated that nitrogen and potassium fertilizers had little effect on the biomass and yield of rice, while the phosphate fertilizers significantly increased the biomass and yield of rice. The total amounts of...
