Queen conch (Lobatus gigas) habitat suitability maps

Despite modest baseline habitat suitability indices across the greater Caribbean, habitat suitability is expected to experience only small changes in either direction (less than 20%) across the region under a near-term atmospheric carbon scenario. Changes are expected to become more pronounced as atmospheric carbon concentrations increases, with habitat suitability declining along the Caribbean cost of Central America, around the Florida Keys, and across the Bahamian Bank. Queen conch habitat suitability is also expected to decline across the Pedro Bank of Jamaica but increase in areas around the bank, which may be associated with a shift of the resource into deeper demersal habitats that may make harvest more challenging. Species-specific projected total habitat suitability index (HSI) and HSI's change or 'anomaly' under different carbon dioxide emission levels, including (A) total HSI for the 1970 to 2000 period; and changes in HSI under scenarios of (B) ~400 ppm and (C) ~565 ppm atmospheric carbon dioxide concentration in the high resolution Earth system model (GFDL CM2.6).
