Unified Interior Regions

This aerial view shows how Faka Union Canal (visible as a straight channel of water) connects the coastal environment, where manatees feed, to freshwater inlets. The Ten Thousand Islands region in the foreground supports sea grass beds where manatees feed. During cold winter months, manatees can swim up Faka Union Canal to a series of residential canals, where the unique

Daylight and fluorescent images of a Montastrea cavernosa coral colony growing on the seawall at Ft. Jefferson, Dry Tortugas National Park. The brownish color of the coral in daylight is largely attributable to chlorophyll contained within the symbiotic algae harbored by the coral. The fluorescent image was taken at night using blue LED lights to stimulate

Daylight and fluorescent images of two coral colonies, Diploria clivosa (left) and Orbicella faveolata (right) growing on the seawall at Ft. Jefferson, Dry Tortugas National Park. The two colonies are separated by an area of dead coral that has been colonized by algae. In the fluorescent image, red corresponds to chlorophyll and green to GFP. Note that

Daylight and fluorescen images of a Orbicella faveolata coral colony in Dry Tortugas National Park. In this colony, the GFP fluorescence is so intense that it overwhelms the weaker red fluorescence of chlorophyll.
