Comparison of bird species richness and individual abundance among different forest edges
次生林不同类型森林边缘的鸟类物种丰富度及个体多度比较

Edges may affect the organisms by causing changes in the biotic and abiotic conditions from some distance into the forest,such as increased amounts of sunlight,high wind speeds,and larger fluctuations in temperature and humidity.Avian species may respond to one or combination of these changes in the landscape as a result of different biological mechanisms.Also,edge effects may affect distribution and behavior of some bird species.Early studies in avian ecology have reported that there were differences of sp...
