Two Belize populations offer opportunity in a desert of genetic diversity.
Efforts to protect Manatees in Florida have not worked, possibly because the sea cows could be hard of hearing, a researcher says. The Sunshine State has created manatee safety zones and slow wake waterways designed to protect them, but the sea mammals repeatedly get in the paths of boats and are slashed by propellers. Florida Atlantic University researcher Edmund Gerstein has measured the hearing abilities of manatees for 17 years, trying to understand why manatees get in the way of boats,...

The West Indian Manatee, Trichechus manatus, is the largest surviving member of the aquatic mammal order Sirenia. It is found along the coastal waters of the West Indies, generally in shallow areas. However, it is known to withstand large changes in water salinity, and so have also been found in shallow rivers and estuaries. These animals are limited to the tropics and subtropics due to an extremely low metabolic rate and lack of thick insulating body fat. Although in the summer they can be...
