Spatial Distribution of Soil Organic Carbon and Total Nitrogen in a Ramsar Wetland, Dafeng Milu National Nature Reserve

The invasion and expansion of Spartina alterniflora in coastal salt marsh wetlands have greatly affected the material cycle of the ecosystem. A total of 372 topsoil samples were collected from 124 sites representing two land-cover types by implementing an unprecedented high sampling density study in the Dafeng Milu National Nature Reserve. Classical statistics and geostatistics were used to quantify soil organic carbon (SOC) and total nitrogen (TN) spatial distribution. Redundancy analysis (RDA) was used to detect correlations between environmental factors, SOC, and TN. The results showed that SOC and TN have moderate variability. The spatial distributions of SOC and TN were similar, and the highest values were observed in the southwest of the study area. In different land cover types, the SOC and TN in the vegetation coverage areas with Spartina alterniflora as the dominant species were significantly higher than those in bare land. RDA showed that TN and aboveground biomass significantly affected the spatial distribution of SOC, while SOC and AGB dominated the spatial distribution of TN.

Scaphisomatini (Coleoptera: Staphylinidae: Scaphidiinae) from two biosphere reserves in eastern China, with descriptions of two new species

Members of the scaphidiine tribe Scaphisomatini collected recently in Tianmushan Biosphere Reserve (Zhejiang) and Wuyishan National Nature Reserve (part of Wuyishan Biosphere Reserve, Fujian), China, are studied. Two species, Scaphisoma krali Löbl, sp. nov. and Scaphisoma sekerkai Löbl, sp. nov., are described from Wuyishan. Baeocera franzi (Löbl, 1973) and Scaphisoma mutator Löbl, 2000 are recorded for the first time from Zhejiang province, and Scaphisoma binhanum (Pic, 1922) and Scaphoxium intermedium Löbl, 1984 are recorded for the first time from Fujian province.

Découverte de Mimumesa wuestneii (Faester, 1951) dans la réserve naturelle nationale du Lac de Grand-Lieu (France, Loire-Atlantique), un site riche en Psenidae (Hymenoptera : Psenidae)

Discovery of Mimumesa wuestneii (Faester, 1951) in the national nature reserve of Lac de Grand-Lieu (Loire-Atlantique, France), a site rich in Psenidae (Hymenoptera: Psenidae). - Mimumesa wuestneii (Faester, 1951), a rare species associated with reed beds, is recorded in France for the first time, in a site which has also been found to be rich in Psenidae (Hymenoptera).

New species of Crossodonthina from Mangshan National Nature Reserve (Nanling National Forest Park), China (Collembola: Neanuridae)

Two new species of the genus Crossodonthina (Collembola: Neanuridae: Neanurinae: Lobellini) are recorded from Mangshan National Nature Reserve, Chenzhou City, Hunan Province and Ruyuan Yao Autonomous County, Guangdong Province, Central-South China. Crossodonthina clavata sp. nov. is characterized by 3+3 uncolored eyes on head; labral chaetotaxy as 0/2, 2; cephalic chaeta O present; cephalic tubercles Dl, L and So fused each other; mandible with 4 basal teeth and five fringed rami; maxilla with two lamellae and each lamella with two apical teeth. Crossodonthina acuminata sp. nov. can be recognized by 3 black eyes per side on head; mandible with 3 basal teeth and 8 rami; all cephalic tubercles independent, chaeta O on tubercle Fr present; cephalic tubercle Di, De on posterior area of head with 2 chaetae each, intermediate between cross and non-cross type chaetotaxy; tubercle De of Th. I with 3(2) chaetae; furcular remnant without chaeta. It is the first record of Neanuridae species from Mangshan National Nature Reserve.

Lespedeza danxiaensis (Fabaceae), a new species from Guangdong, China, based on molecular and morphological data

Lespedeza danxiaensis (Fabaceae), a new species from Danxiashan National Nature Reserve in Guangdong Province, is described and illustrated. The new species is morphologically similar to Lespedeza pilosa, but it can be easily distinguished by its thin leathery leaflets and long peduncles. Phylogenetic analysis based on ITS confirmed that the new species belongs to Lespedeza subg. Macrolespedeza. The new species is the first known species of Lespedeza endemic to Danxia landform and is currently only known from Mount Danxia, Guangdong.
