Complete chloroplast genome of , an endemic fern in China.

is the only aquatic pteridophyte in China with high research value of phylogeny. It is in endangered status. A conservation strategy is therefore imperative for this endangered pteridophyte.

[Characteristics of soil microbial biomass carbon and nitrogen and its seasonal dynamics in four mid-subtropical forests].

Taking evergreen broad-leaved forest in mid-subtropical areas, and its converted Phoebe bournei, Phyllostachys heterocycla and Cunninghamia lanceolata plantations as research objects, microbial biomass carbon (MBC) and nitrogen (MBN) in the surface (0-10 cm) and deep soil layer (40-60 cm) were measured by chloroform fumigation and extraction method, with their seasonal dynamics and the relationships with soil physicochemical properties in four types of forests being investigated. The results showed that the MBC and MBN in the surface soil was the highest in the evergreen broad-leaved forest, followed by P. bournei, P.
