Crabs in a Cove (image) Princeton University Share Print E-Mail Caption Research conducted through Princeton University found that erratic rainfall -- which could become more irregular as a result of climate change -- could be detrimental to animals that migrate with the dry-wet seasonal cycle. The researchers studied the annual mating migration of the land-dwelling Christmas Island red crab in order to help scientists understand the consequences of climate change for the millions of migratory animals in Earth's tropical zones.
