Four interesting new papers – Parks & Poverty, Pleistocene extinctions, Evosystem services, and making better assessments

1) Parks can help local people.  Protected areas reduced poverty in surrounding areas in Costa Rica and Thailand by K.S. Andam and other in PNAS (doi:/10.1073/pnas.0914177107)

2) Evidence for a long Anthropocene.   Pleistocene extinctions of mega-herbivores may have lead to global cooling due to reduction on methane.  Methane emissions from extinct megafauna by Felisa A. Smith and others in Nature Geoscience(doi:/10.1038/ngeo877)

3) Evosystem services, the services of evolution.  By Daniel Faith and others.  Evosystem services: an evolutionary perspective on the links between biodiversity and human well-being (doi:10.1016/j.cosust.2010.04.002).  Evosystem services seem fall into the category of regulating and supporting services to me.  However, an interesting idea.  It would be nice to see it further developed.

4)  A bit older, Reflections on how to make global scientific assessments better. From new journal Current Opinion in Environmental Sustainability How to make global assessments more effective: lessons from the assessment community by Dale Rothman and others. (doi:10.1016/j.cosust.2009.09.002)
