The finding appears today on the Web site of the American Chemical Society’s...Species unique to tidal marshes face threats
Tidal marshes cover only about 45,000 square kilometers worldwide--about the area of Denmark. In comparison with other habitats, tidal marshes support few nonaquatic vertebrate species, but their unique characteristics have led to the evolution of species and subspecies that are endemic (found nowhere else). These endemic species and subspecies, which seem to be largely restricted to North Americ...TIDAL WAVE Sp Handheld Capnograph/Pulse Oximeter
