Bird Distribution And Conservation In The Ailao Mountains, Yunnan, China, Zhijun Wang, Chris Carpenter, Stephen S. Young Dec 1999

Bird Distribution And Conservation In The Ailao Mountains, Yunnan, China, Zhijun Wang, Chris Carpenter, Stephen S. Young

Stephen Young

Results from a long-term ecological study carried out by Chinese and American researchers in the Xujiaba Ecological Reserve within the Ailao Shan Nature Reserve show the importance of the Ailao Mountains as a sanctuary for numerous bird species. Natural forest cover is decreasing throughout Southwestern China and adjacent Southeast Asia leading to a diminished habitat for plants and animals throughout the region. Remnant primary and secondary forests in the Ailao Mountains supply habitat for an abundance of bird species and other wildlife, many facing possible extinction. This study analyzes the bird diversity of three different ecosystems: primary broad-leaved evergreen forest …

First-brood mothers were highly responsive until 3 days after their eggs hatched. Second-brood mothers, however, were only responsive until 1–2 days post-hatching. This effect was associated with differences in age and parity, but not experience, because …

Review Essay Of Two Books On The History Of Science, Charles Kay Smith

Charles Kay Smith

Contrary to what I was taught in high school in the mid-1940s, science is no longer defined as an inductive methodology for immaculately conceiving culture-free truth after sifting through a huge data base of objective facts. For without some prior hypothesis to guide her, a scientist would not be able to decide which facts were relevant. Nowadays hypotheses can come from anywhere in the imagination or culture within which the scientist is working. The importance of a scientific hypothesis is that it be framed in such a way that it can be falsified when tested. Science now has a history …
