Wildlife corridors also aid seed dispersal

Category : science

"Landscape Corridors Provide Pathway For Seed Dispersal; Birds Help Habitats Maintain Diversity." Source: National Science Foundation, via Science Daily, 07 Jul 2005.

"Wildlife corridors--clear tracts of land intended to help maintain biodiversity by allowing animals to move between otherwise isolated natural areas--may also aid stationary plants in the same way. A study at an outdoor experimental landscape in S.C., has found that berry eating bluebirds transfer more of the plants' seeds between habitats connected by corridors than between those that are unconnected.

Biologists placed wax myrtle branches with ripe berries in central clearings, marking the berries with a harmless florescent dye so that they could track the berries' whereabouts. Using the florescent markers, they were able to identify seeds that came from plants in the central patches. Seeds were more likely to be found in the central clearings of connected patches than in the central clearings of isolated patches.

The study, which appears this week in the journal Science, is important because it suggests that greenways in urban and suburban communities help plants as well as animals.

"The work illustrates how basic research, in this case studying bird behavior, can provide important information needed in land management decisions," said Alan Tessier, program director in NSF's division of environmental biology, which funded the research."
