Which of the following is a generally accurate statement about the current research regarding forest fragmentation?

#Unit 9. Diversity of Life Forms

Fragmented forests promote biodiversity because they result in the combination of forestedge species and forest-interior species.
In fragmented forests, the number of forested-adapted species tend to decline and the number of edge species tend to increase.
Fragmented forests are the goal of conservation biologists who design wildlife reserves.
The disturbance of timber extraction causes the species diversity to increase because of the new habitats created.
