A new subgenus and two new species of the troglobitic genus Dongodytes Deuve from Guangxi, China (Coleoptera, Carabidae), 2011, Mingyi Tian

In the present paper, a new subgenus and two new species of the cave-dwelling genus Dongodytes Deuve, 1993 are described and illustrated:Dongodytes (Dongodytodes) deharvengi, subgen. and sp. nov. andDongodytes baxian, sp. nov. from Du’an Xian, North Guangxi, China.

Hydroecogeochemical effects of an epikarst ecosystem: case study of the Nongla Landiantang Spring catchment, 2012, Shen L. , Deng X. , Jiang Z. , Li T.

A typical small-scale epikarst ecosystemusually consists of an epikarst zone, soil and vegetation. In this study, to determine the hydro-eco-geochemical effects of an epikarst ecosystem in subtropical humid area, the samples of vegetation, soil, soil microbes, rainfall, throughfall, stem flow, soil water and epikarst springs of Nongla Village, Mashan County, Guangxi in China were collected and analyzed. The research results have shown in the epikarst ecosystem, the conductivity, temporary hardness and total carbon increased continuously in hydro-ecochemical cycle; the vegetation–soil system conducted the transformation and transference of carbon in hydro-ecochemical cycle; the vegetation layer was the major source for organic carbon, while the soil layer was of the important chemical field for the conversion of organic/inorganic carbon and HCO3 –, which would affect the epikarst dynamical system; for most ions, the vegetation layer and shallow soil layer presented more leaching effect than absorption, in contrast, the deep soil layer behaved oppositely. The vegetation layer and shallow soil layer leached ions, and deep soil layer absorbed them. With the plant community presenting in a positive succession, the epikarst ecosystem trended to be stabilized gradually, which made the hydro-eco-geochemical effects to be adjusted and controlled more effectively

INVESTIGATIONS OF LARGE SCALE SINKHOLE COLLAPSES, LAIBIN, GUANGXI, CHINA, 2013, Gao Yongli, Luo Weiquan, Jiang Xiaozhen, Lei Mingtang, Dai Jianling

A series of sinkholes collapsed at Jili village and Shanbei village, Laibin Guangxi, China in June 2010. A large underground stream exists in the north-south transect of the study area and passes the collapse site. Preliminary investigations revealed that extremely heavy rainfall between May 31 and June 1 2010 may have triggered this collapse event. The precipitation, as high as 469.8 mm within one day, was a record high in the study area. A long period of drought in 2009 followed by extremely heavy rainfall along with cave roof collapse may have caused the collapse event on June 3 2010. The “water hammer” effect and collapse-triggered earthquakes caused severe ground failure and fractures in residential houses and Jili Dam. Several collapse events were caused by extreme weather conditions in Guangxi over the past few years. Further studies of the relationship between extreme weather events and sinkhole collapses will help minimize the damage or impact to human infrastructure by avoiding areas susceptible to collapse or by designing infrastructure to better withstand subsidence

Occurrence of troglobitic clivinines in China (Insect: Coleoptera: Carabidae), 2013, Tian, M.

A new genus, Guiodytes gen. nov., and two new species, G. cavicola sp. nov. and G. bedosae sp. nov., of the ground beetle tribe Clivinini (Coleoptera: Carabidae) are described from two caves of Guangxi, southern China. Guiodytes gen. nov. is characterized. It is the first genus of troglobitic clivinines discovered in Asia, and its relationships with other clivinines remain unclear.
