不同栖息地类型对东北大兴安岭红花尔基地区鸟类群落结构与组成的影响

open access: yes野生动物学报, 2010
2001~2002年和2004~2005年分别于5~6月,在内蒙古红花尔基地区,应用样方调查法研究了环境因子与鸟类群落结构的关系,结果表明:(1)在草地生境中,鸟类多样性与草的高度和盖度相关性显著,鸟的密度与草的高度和盖度相关性不显著。(2)在樟子松森林生境中,叶层高度多样性指数(FHD)与鸟类多样性指数(BSD)呈正相关(r=0.814 ...

Functional homogenization of terrestrial mammals outside protected areas in the Hengduan Mountains, China

open access: yesConservation Biology, EarlyView.
Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...
