Drought can severely affect carbon dynamics in forest ecosystems through impacts on carbon storage, reduced carbon fixation, abatement of the carbon sink function, and alteration of carbon sink-source relationships. Currently, little is known about the effects of drought on the productivity and spatial patterns of carbon in bamboo forests. The objective of this study was to assess the effect of imposed...
The monitoring of animal populations is necessary to conserve and manage the rare or harvest species and to understand the population change over several years. We used distance sampling methods to estimate seasonal density of blue sheep in a 2,740 km2 area of Helan Mountain region by walking along 32 transect lines from winter 2003 to autumn 2005. In all, 367–780 blue sheep were observed in 91–143...
