Spatiotemporal dynamics of grassland aboveground biomass in northern China and the alpine region: Impacts of climate change and human activities
<p>We employed CASA model to estimate grassland Net Primary Productivity and aboveground biomass A(AGB) from meteorological and GIMMS Normalized Difference Vegetation Index (NDVI) remote sensing data in northern China. We analyzed the dynamics of grassland AGB and impacts climate change and human activites.</p>
Restoration of vegetation and soil in the Horqin Sandy Land, Northern China
<p>These data aimed to clarify the response of vegetation and soil properties to different restoration measures and dune topography, and to quantify dynamics over time. Vegetation and soil characteristics were evaluated at different topographic positions on dunes in the Horqin Sandy Land, with 5-, 25- and 35-year monitoring periods for grazing exclusion and tree planting, and 5- and 25-year monitoring periods for shrub planting.</p>

Population differentiation and intraspecific genetic admixture in two Eucryptorrhynchus weevils (Coleoptera: Curculionidae) across northern China
<p><span>Inreasing damage of pests in agriculture and forestry can arise both as a consequence of changes in local species and through the introduction of alien species. In this study, we used population genetics approaches to examine population processes of two pests of the tree-of-heaven trunk weevil (TTW), <em>Eucryptorrhynchus brandti</em> (Harold) and the tree-of-heaven root weevil (TRW), <em>E. scrobiculatus</em> (Motschulsky) on the tree-of-heaven across their native range of China. We analyzed the population genetics of the two weevils based on ten highly polymorphic microsatellite markers. Population genetic diversity analysis showed strong population differentiation among populations of each species, with FST ranges from 0.0197 to 0.6650 and from -0.0724 to 0.6845, respectively. Populations from the same geographical areas can be divided into different genetic clusters, and the same genetic cluster contained populations from different geographical populations, pointing to dispersal of the weevils possibly being human-mediated. Redundancy analysis showed that the independent effects of environment and geography could account for 93.94% and 29.70% of the explained genetic variance in TTW, and 41.90% and 55.73% of the explained genetic variance in TRW, respectively, indicating possible impacts of local climates on population genetic differentiation. Our study helps to uncover population genetic processes of these local pest species with relevance to control methods.</span></p>

Hemiboea shimentaiensis (Gesneriaceae), a new species from northern Guangdong, China
<p><em>Hemiboea shimentaiensis</em> (Gesneriaceae), a new species from northern Guangdong, China, is described and illustrated. It is most similar to <em>H. gamosepala</em>, <em>H. rubribracteata </em>and <em>H. malipoensis</em> in the nearly white corolla, which appears in a few species of <em>Hemiboea</em>, and nearly glabrous inner base of the corolla tube. It can be easily distinguished from the latter three species by the stoloniferous habit, distinct silvery veins, glabrous corolla except for a ring of hairs inside, anther coherent along ventral face when young, but cohering apically at maturity, three separate staminodes with lateral ones resembling deformed anthers, and with few sterile pollen grains inside, to antheroids at the tips of the staminodes. The life cycle and fluctuations in the population are unknown and need further study, the conservation status of <em>H. shimentaiensis</em> was not assessed.</p>
