Christmas crabs

Article Abstract:

Up to 120 million land-dwelling red crabs, Geocarcoides natalis, migrate annually from the rainforest on Christmas Island in the Indian Ocean to the sea to breed. Biologists from the Australian Nature Conservation Agency are studying the crabs' migration patterns and physiology, as well as the part the crustaceans play in the island's rainforest ecology. A detailed account of the annual migration is provided. Other aspects of red crab behavior and physiology are discussed.

Education on the half shell

Article Abstract:

The elementary and high school students are participating in an oyster gardening program called Schools Restoring Oysters to the Chesapeake (SROC). The students visit their local tributary sites, clean, test water quality, identify sea squirts, tubeworms, gobies and many others and are able to reproduce the oysters, which is further released onto sanctuary reefs.

Crab lovers, celebrate

Article Abstract:

The red crabs are highly valued on Christmas island because their burrowing and leaf-foraging activities maintain the rain forest's rich soils and vegetations, much like earthworms do. The red crab populations in the Australian territory have declined by as much as one-third due to attacking supercolonies of yellow crazy ants.
