Abstract
Macrofungi not only play an important role in pollution control and other environmental protection measures, but also an important resource in food and pharmaceutical industries. However, the diversity of the macrofungal community in the core habitat of the giant panda in Bifeng Gorge, China is still inadequate. In the current study, the macrofungal diversity in Bifeng Gorge was investigated using morphologic and molecular biological methods. The results show that 275 species were found which were classified into 122 genera from 52 families. Up to 54.55% of the species were classified into various families, including Russulaceae, Strophariaceae, Agaricacea, Tricholomataceae, Psathyrellaceae, Mycenaceae, Marasmiaceae and Polyporaceae. The microfungi thrive in different areas within the Bifeng Gorge, which could be roughly classified into six ecological communities, namely, evergreen broadleaf forest (I), Cryptomeria fortunei forest (II), Metasequoia glyptostroboides forest (III), bamboo forest (IV), mixed bamboo- broadleaf forest (V) and grassland (VI). Further studies revealed that the order of the richness index (R) was I > II > V > III > IV > VI, evenness index (E) and dominance index (D) were V > III > IV > I > II > VI, and species diversity index (H’) was I > V > III > IV > II > VI. The data suggests that despite the lagged sporophore peak compared with the highest temperature, macrofungal diversity was positively related to the temperature in the area. Key words: Bifeng Gorge, biodiversity, macrofungi, vegetation type.
Highlights
Bifeng Gorge is the core habitat of the giant panda in China, located in the North Yucheng District in Ya’an, Sichuan, China
Macrofungal Resources According to the morphologic characteristics and sequence information, about 275 macrofungal are present in Bifeng Gorge
The temperature from September to November was slightly lower than that in April to June, but the quantity increased. Both vegetative communities and animals influence the macrofungal habitat in the forest ecosystem (Crabtree et al, 2010; Hustad et al, 2011), especially the core giant panda habitat, and in turn, the macrofungi are the essential decomposers that maintained regional ecological balance for plants and animals living
Summary
Bifeng Gorge is the core habitat of the giant panda in China, located in the North Yucheng District in Ya’an, Sichuan, China. The area is a famous AAAA grade scenic tourist destination. It stands in the lower mountain zone of the Southwestern Qionglai Mountains with rolling hills and abundant creeks. Bifeng Gorge lies on the moist subtropical monsoon region in the mid-latitude inland where the main soil composition of the mountainous yellow soils and the formation is sandy clay rock of the Upper Cretaceous Guankou Formation (Tang et al, 2007). The main vegetation type is the partially humid subtropical evergreen broadleaf forest based on the Castanopsis–Schima forest and the Lauraceae forest (Ren and Liu, 2008), and at long intervals, the Cryptomeria fortune forest and bamboo, among others. Numerous macrofungi have very high value in research and development
