The U.S. Fish and Wildlife Service (USFWS 2001) estimates a Florida population of around 3,276 animals based on a Florida-wide count during January 5-6, 2001. A subpopulation of approximately 400 animals is associated with the springs north of Tampa Bay. Many animals succumb annually to collisions with boats and from the effects of a suite of neurotoxins (brevetoxins) produced by the red-tide dinoflagellate Karenia brevis. The Florida manatee is Federally classified as an 'endangered' species, but on April 9, 2007 the U.S. Fish and Wildlife Service recommended 17 that the designation be reduced from endangered to 'threatened'. Manatees are poor thermal regulators. Animals exhibit a high degree of thermal conductance (poor insulation) with relatively low metabolic rates (Rouhani et al. 2006) and are generally vulnerable to exposure to temperatures below 20 o C, although some 17 http://www.fws.gov/southeast/news/2007/r07-057.html ____________________________________________________________________________________________ Proposed Minimum Flows and Levels for Weeki Wachee River Page 82 of 164 Biological Characteristics
