This design enabled them to control for several factors. The total area of the patch plus the corridor, or the patch plus the wings was the same. The total amount of edge (perimeter of each patch) was similar between the two treatments. Both patch types were the same distance from the central patch. Below are 4 examples of ways Damschen and her colleagues could have designed their experiment. Identify what is wrong with each design.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
