Industry:Biology

Industry:Biology
The unique properties in an ecotone (plant variety, animal density, biological diversity), the zone where two communities meet.
Industry:Biology
Volcanically raised islands that arc near subduction zones where one continental plate rides over another. See Plate Tectonics.
