Twenty-seven Colletotrichum isolates associated with asymptomatic tissues of bamboo (Bambusoideae, Gramineae) were isolated from Anhui, Beijing, and Guangxi in China. Based on multilocus (internal transcribed spacer [ITS], glyceraldehyde-3-phosphate dehydrogenase [GAPDH], chitin synthase [CHS], actin [ACT], beta-tubulin [TUB2]) phylogenetic analyses and morphological characteristics, three species were distinguished, including two novel species, C. bambusicola and C. guangxiense, and one known species, C. metake, which is a first report for China. These species have hitherto only been discovered on Bambusoideae, indicating that they probably have host preference. [ABSTRACT FROM AUTHOR]

Under the dual pressures of the socio-economic development and the increase in population density, the ecological environmental quality issues in Anhui Province have become increasingly prominent, which seriously handicap the sustainable development of regional economy, and it is more important to evaluate ecological environmental quality. By using the data of ecological environment, society, economy and population in Anhui Province, this paper measures ecological footprint, ecological environmental carrying capacity and ecological deficit and surplus in Anhui Province based on ecological footprint. The results show that ecological environmental quality in Anhui Province is not in the best state of the coordinated development, and the relationship between the supply and the demand of per ecological footprint almost is not in balance.
