Flexible Symbiotic Associations of With Five Typical Coral Species in Tropical and Subtropical Reef Regions of the Northern South China Sea.

The coral symbiont plays important roles in the adaptation of coral to environmental changes. However, coral- symbiotic associations are not well-understood in the South China Sea (SCS) whilst considering environmental factors and host taxa. In this study, next-generation sequencing of the internal transcribed spacer region 2 (ITS2) marker gene was used to explore the symbiotic associations between and five typical coral species across tropical and subtropical reef regions of the SCS.

[Study on meteorological factors-based neural network model of malaria].

Objective: In order to provide reliable data for strategies development on prevention, a meteorological factors-based predicating model for malaria forecast was studied.

Methods: Data on malaria occurrence and climate changes from 1994 to 1999 in counties in Yunnan province was collected and analyzed with software packages of FoxPro 6.0 and Excel 5.
