Abstract:
... Existing methods of restoring vegetation to abandoned coalmine wasteland are inapplicable to the harsh Qinghai-Tibet Plateau because it faces several unique challenges, including a perennially low temperature, strong winds and solar radiation, the presence of permafrost, and the lack of suitable topsoil, all of which are absent from low-altitude regions. It remains unknown which restoration measur ...

Abstract:
... The Agglomeration Bonus has been shown to be a potentially successful policy to reunite fragmented habitat and increase conservation enrollment in laboratory testbed experiments. Yet, one key criticism has been that land prices have been assumed exogenous and fixed in these experiments. In the field, voluntary conservation enrollment by landowners will likely affect the value of the surrounding la ...
Nipponia nippon; birds; case studies; genomics; museums; research projects
Abstract:
... In the bird collection of the Natural History Museum at Tring (NHMUK), and no doubt in many analogous collections elsewhere, older specimens are increasingly likely to have become divorced from some, or even all, of the data that once accompanied them. As the utility of such specimens for research depends in large part on their accompanying data, it is important, though time-consuming, to try to r ...
