Biological Dynamics of Forest Fragments Project
The Biological Dynamics of Forest Fragments Project, originally called the Minimum Critical Size of Ecosystems Project is a large-scale ecological experiment looking at the effects of habitat fragmentation on tropical rainforest; it is one of the most expensive biology experiments ever run. The experiment, which was established in 1979 is located near Manaus, in the Brazilian Amazon. The project is jointly managed by the Smithsonian Institution and INPA, the Brazilian Institute for Research in the Amazon.The project was initiated in 1979 by Thomas Lovejoy to investigate the SLOSS debate. Initially named the Minimum Critical Size of Ecosystems Project, the project created forest fragments of sizes 1 hectare (2 acres), 10 hectares (25 acres), and 100 hectares (247 acres). Data were collected prior to the creation of the fragments and studies of the effects of fragmentation now exceed 25 years.As of October 2010 562 publications and 143 graduate dissertations and theses had emerged from the project.
