Natural resources knowledge shrinks as economies grow
New research shows that Indonesians can identify 71% of local plants when asked, while the British can name only 24%.

Most people realize that as a society becomes more industrialized, individual knowledge about the natural world diminishes. New research published in ES&T (DOI: 10.1021/es070837v) analyzes interviews done with various age groups living in Indonesia, India, and the U.K. to find out how much ecological knowledge is lost, when it is lost, and how that loss affects society's ability to manage natural resources as industrialization occurs. The findings indicate that future efforts to conserve biodiversity on a global scale are at great risk. ---

Coralline algae will suffer as oceans acidify | Practical Fishkeeping magazine --- Corals are not the only reef organisms to suffer directly from increased ocean acidification, according to a study to be published in the journal Nature Geoscience.  Ilsa Kuffner, Andreas Andersson, Paul Jokiel, Ku'ulei Rodgers and Fred Mackenzie carried out a seven-week experiment examining the effects of increased ocean acidification on crustose coralline algae, a group of calcifying algae that is important in many shallow water habitats, including coral reefs.  The authors constructed six fibreglass mesocosm tanks were supplied with flowing sea water pumped from the edge of a coral reef in Hawaii.
