THIS ISSUE

摘要

This week's Nature is the third of three special issues (previously 20 November 2008 and 12 February 2009) marking the Darwin bicentenary. The theme is biodiversity and how to preserve it. Though still endangered, the golden lion tamarin is a conservation success story in an area where successes are rare: with re-introductions and efforts to preserve its Brazilian forest habitat, the population of the primate has been stabilized [News Feature p. 266].
