    Our Story The Florida Keys Scenic Highway (FKSH) corridor runs from Mile Marker 110, north of the spectacular Jewfish Creek Bridge, to Mile Marker 0 in Old Town Key West. The scenic highway corridor also extends five miles on each side of the highway. So, the FKSH truly encompasses all of the Florida Keys, its natural wonders, and its communities. Through efforts beginning in 1996 with numerous public meetings and workshops to create the Corridor Management Plan, the FDOT designated the FKSH a Florida Scenic Highway in 2001. In 2007, the Florida Keys Mission Statement Scenic Corridor Alliance (FKSCA) was To enhance the scenic image, preserve our established as the corridor management entity heritage and diversity, and promote the natural responsible for implementing the goals and beauty of the Florida Keys Scenic Corridor. objectives concerning the FKSH. The FKSCA completed its Corridor Management Plan Five- Year Update in fall of 2008 and applied for designation in the National Scenic Byways Program. The FKSCA proved our highway corridor meets the designation criteria of being considered a “destination unto itself” and “providing an exceptional travel experience.” Our scenic and recreational intrinsic qualities “are those which best represent the nation, are nationally recognized, and contain one-of-a- kind features that do not exist elsewhere.” The Florida Keys Scenic Highway is a natural fit. In October 2009, the Federal Highway Administration designated the Florida Keys Scenic Highway as an All-American Road – Florida Keys Scenic Corridor Alliance the highest status in the National Scenic P.O.

  • And Individual-Level Reproductive Parameters of the Blue-Legged Hermit Crab Clibanarius Tricolor
    Small-scale spatial variation in population- and individual-level reproductive parameters of the blue-legged hermit crab Clibanarius tricolor J. Antonio Baeza1,2,3 and Donald C. Behringer4,5 1 Department of Biological Sciences, Clemson University, Clemson, SC, United States 2 Smithsonian Marine Station at Fort Pierce, Fort Pierce, FL, United States 3 Departamento de Biologia Marina, Universidad Catolica del Norte, Coquimbo, IV Region, Chile 4 School of Forest Resources and Conservation, University of Florida, Gainesville, FL, United States 5 Emerging Pathogens Institute, University of Florida, Gainesville, FL, United States ABSTRACT Management of the few regulated ornamental fisheries relies on inadequate information about the life history of the target species. Herein, we investigated the reproductive biology of the most heavily traded marine invertebrate in the western Atlantic; the blue-legged hermit crab Clibanarius tricolor. We report on density, individual-level, and population-level reproductive parameters in 14 populations spanning the Florida Keys. In C. tricolor, abundance, population-level, and individual-level reproductive parameters exhibited substantial small-scale spatial variation in the Florida Keys. For instance, the proportion of brooding females varied between 10–94% across localities. In females, average (±SD) fecundity varied between 184 (±54) and 614 (±301) embryos crab-1 across populations. Fecundity usually increases with female body size in hermit crabs. However, we found no effect of female body size on fecundity in three of the populations. Altogether, our observations suggest that C. tricolor may fit a source- sink metapopulation dynamic in the Florida Keys with low reproductive intensity and absence of a parental body size—fecundity relationship resulting in net reproductive Submitted 25 October 2016 loses at some localities.
