The complete mitochondrial genome of (Forel 1901) (Hymenoptera: Formicidae) and its phylogenetic relationship.

(Forel 1901) is an important arboreal ant species commonly found on (Carr.) in Lishui, Zhejiang, China. This study analyzed the mitochondrial genome sequence of and discussed its phylogenetic relationship in Hymenoptera.

[Effect of adding different amounts of wheat straw and phosphorus on soil microorganism community].

A pot experiment was conducted to study the effects of adding different amounts of wheat straw (0 g x kg(-1), N0; 2.08 g x kg(-1), N1) and phosphorus (0 mg x kg(-1), P0; 100 mg x kg(-1), P1; 200 mg x kg(-1), P2; 400 mg x kg(-1), P3) on microorganism community in a soil of low-phosphorus. Adding straw and phosphorus had significant effects on the soil microbial total biomass (MTB), bacterial biomass (MB), fungal biomass (FB), and fungi to bacteria ratio (F/B), which all decreased in order of N1P1>N1P0>N1P2>N1P3>N0P1>N0P2>N0P3.

[Diversity of soil fauna in corn fields in Huang-Huai-Hai Plain of China under effects of conservation tillage].

An investigation was made on the abundance and diversity of soil fauna in the corn fields under conventional and conservation tillage in Huang-Huai-Hai Plain of China. The abundance and diversity of soil fauna were higher at corn maturing (September) than at its jointing stage (July), and higher at jointing stage under conservation tillage than under conventional tillage. Soil fauna mainly distributed in surface soil layer (0-10 cm), but still had a larger number in 10-20 cm layer under conservation tillage.
