This paper deals with four genera and eight species of the subfamily Dataminae Rehn & Rehn, 1939 from China. One new genus and four new species, Hainanphasma cristata Ho gen. nov. spec. nov., H. diaoluoshanensis Ho spec. nov., Pylaemenespui Ho spec. nov. and Pylaemenes shirakii Ho & Brock spec. nov., are described and illustrated. A new combination is proposed: Planispectrum hainanensis (Chen &...

Vegetation patchiness is common in degraded grasslands. enhances the spatial variability of grassland soil organic carbon and total nitrogen. Stripped vegetation patches have a great impact on ecosystem (C) nitrogen (N) storage. Using field surveys, we examined effects storage four typical alpine grass species (viz: Leymus secalinus, Koeleria pers, Stipa aliena, Leontopodium nanum ). The result...

Topography is an important factor in determining vegetation patterns in grasslands. We collected frequency of occurrence data from transects on dune tops, south-facing slopes, north-facing slopes, and interdunal valleys in the eastern Sandhills of Nebraska to determine the effect of topographical position on plant species composition. We used canonical discriminant analysis to separate the four...
