Question

n the studies by Haddad and colleagues at the Savannah River Ecological Laboratory, habitat corridors increased the movements of pollinators and enhanced fruit production. What was the control used in these experiments? Select one: a. GIS to monitor the movements of the pollinators b. An electric fence that stopped the movement of pollinators c. Pesticides that prevented pollinators from entering certain corridors d. Winged patches with extensions that resembled corridors but did not lead anywhere e. No control was used; this was a natural experiment.

Answer 1

The habitat fragmentation resulted in the decline of pollinator population around the world.So habitat corridors are the solution for the movement of organisms between the isolated habitats.Especially the pollinator population is found to be increased by adding the habitat corridors.This can be achieved by using GIS mapping tool.This tool enables the entry of data showing the number of pollinators and other flowering plants data.This helps to maintain a pollinator friendly habitat corridor by providing continuing source of food,nesting sites and water and it can enhance the pollinator movement and increased fruit production.So the control used in the experiment must be a. GIS to monitor the movements of the pollinators.
