Mushrooms can be found in forests worldwide and have long been exploited as resources in developed economies because of their important agro-industrial, medicinal and commercial uses. For less developed countries, such as those within the Greater Mekong Subregion, wild harvesting and mushroom cultivation provides a much-needed alternative source of income(More)
Climate change affects various facets of life but there is little data on its effects on wild mushroom fruiting. Yunnan Province in China is a rich source of wild mushrooms and has experienced a temperature rise over recent decades. This has resulted in warmer temperatures but the impacts of these changes on mushroom production lack documentation. We(More)
Two new truffles species, Tuber alboumbilicum and Tuber pseudobrumale are described based on collections from Southwest China. T. alboumbilicum is characterized by its white umbilicate ascomata. T. pseudobrumale is similar to T. pseudoexcavatum, but differs in spinulose ascospores. Molecular analysis also supported T. alboumbilicum and T. pseudobrumale as(More)
During a north–south latitudinal survey of aquatic fungi on submerged wood and herbaceous material in streams in the Asian region, we collected several hyphomycetous taxa. This paper is part of a series where we provide illustrated accounts of these taxa and place them in a natural classification in the fungi. DNA sequence based phylogenies in recent(More)
" We estimate the straw-fired power generation costs in Jiangsu Province, China. " The causes for the deficit of straw-fired power generation plants are identified. " Poor management is the primary factor for explaining the deficit of the plants. a b s t r a c t As one of the most developed provinces in China, Jiangsu Province has been actively developing(More)
This paper proposes a centralized data envelopment analysis (DEA) model for industrial optimization based on several different production technologies among several regions. We developed this model based on improved Kuosmanen environmental DEA technology, which avoids positive shadow price on undesirable outputs. We also designed a dual model for our(More)
The decision on the location of a straw-based power generation plant has a great influence on the plant's operation and performance. This study explores traditional theories for site selection. Using integer programming, the study optimizes the economic and carbon emission outcomes of straw-based power generation as two objectives, with the supply and(More)
This paper proposes a real options model for evaluating the biomass power generation investment in China. The uncertainties in the market price of electricity, CO 2 price and straw price are considered. Meanwhile the dynamic relationship between installed capacity and fuel cost, as well as the long-term reduction of subsidy are described. Two scenarios,(More)
