Lovejoy discovered that when these forests became small patches, they lost their biodiversity, trees started to die, and birds left. The smallest groves were all edge, biologically speaking.
Purpose of the Experiment
Lovejoy's experiment tested the effect of the cutting off of natural areas into small parcels, a process that has taken place throughout most of the world.
Natural Biological Islands
As one would expect, many tropical islands are also naturally cut off from the outside world, while some of these are less diverse than the continents, other islands such as the Galapagos and Madagascar contain species found nowhere else.

- Central Park
