Effect of karst rocky desertification on soil fungal communities in Southwest China

P. C. Wang, Mo, B. T., Chen, Y., Zeng, Q. F., Wang, L. B., Wang, P. C., Mo, B. T., Chen, Y., Zeng, Q. F., and Wang, L. B., Effect of karst rocky desertification on soil fungal communities in Southwest China, vol. 15, p. -, 2016.

Karst mountainous ecosystems are associated with karst rocky desertification (KRD), which can greatly impact soil structure and function. Despite the importance of soil microbes as a major factor maintaining ecosystem stability, we know little about the effect on soil fungal communities of KRD in karst regions. We investigated this relationship across a gradient of KRD soils from Guizhou, China by polymerase chain reaction and denaturing gradient gel electrophoresis (PCR-DGGE).

Microbiological quality and bacterial diversity of the tropical oyster Crassostrea rhizophorae in a monitored farming system and from natural stocks

M. T. Silva Neta, Maciel, B. M., Lopes, A. T. S., Marques, E. L. S., Rezende, R. P., and Boehs, G., Microbiological quality and bacterial diversity of the tropical oyster Crassostrea rhizophorae in a monitored farming system and from natural stocks, vol. 14, pp. 15754-15768, 2015.

Microbiological evaluation is one of the most important parameters for analyzing the viability of an oyster farming system, which addresses public health and ecological concerns. Here, the microbiological quality of the oyster Crassostrea rhizophorae cultivated in a monitored environment and from natural beds in Bahia, northeastern Brazil, was determined. Bacterial diversity in oysters was measured by polymerase chain reaction-denaturing gradient gel electrophoresis.
