Abstract Salinization has led to the deterioration of the ecological environment, affected the growth of plants, and hindered the development of agriculture and forestry. Arbuscular mycorrhizal (AM) fungi, as important soil microorganisms, play significant physiological and ecological roles in promoting plant nutrient absorption and improving soil structure. Puccinellia tenuiflora (Turcz.) Scribn. et Merr. in Songnen saline-alkaline grassland was selected as the research object to observe AM fungal colonization of the roots and explore the species and diversity of AM fungi in symbiotic association with P. tenuiflora. This study showed that AM fungi colonized in P. tenuiflora roots and formed a typical… More >

Abstract Hevea brasiliensis is one of the important economic trees with a great economic value for natural rubber production. Symbiosis between roots of H. brasiliensis and arbuscular mycorrhizal fungi (AMF) is widely recognized, and can provide a range of benefits for both of them. Hainan Island harbors is one of the largest plantations of H. brasiliensis in China, whereas the information regarding the diversity of AMF in the rhizosphere of H. brasiliensis on this island is scarce. The diversity of AMF species in the rhizosphere of rubber tree plantations in Hainan was investigated in this study. A total of 72 soil… More >

Abstract The objective of this study was to analyze the relationships between total aboveground plant biomass versus altitude, latitude, longitude, mean annual temperature, mean annual precipitation, and species diversity. Simple linear regression analysis was used to study these relationships. Results showed that altitude was significantly, positively (R²= 0.038, P<0.01) related with total plant aboveground biomass. Meanwhile, when longitude (R²= 0.124, P<0.001) and latitude (R²= 0.221, P<0.001) increased, total aboveground biomass decreased. The relationship between biomass and mean annual precipitation was significantly, positively linear (R²= 0.149, P<0.001). Mean annual temperature was significantly, negatively correlated with biomass (R²= 0.145, P<0.001). The relationship between… More >

Abstract Grasslands are one of the most widespread landscapes worldwide, covering approximately one-fifth of the world’s land surface, where grazing is a common practice. How carbon storage responds to grazing in steppes remains poorly understood. We quantified the effects of grazing on community composition and species diversity, and carbon storage in two typical grasslands of northeastern China, one in Horqin and the other one in Hulunbeier. In both grasslands, grazing did not influence plant species diversity. However, it substantially decreased aboveground carbon by 31% and 54% in Horqin and Hulunbeier, respectively. Fenced and grazing treatments showed a similar belowground carbon at… More >
