Book Description
Fossil data from multiple locations indicates that Atlantic elkhorn coral, Acropora palmata, formed shallow reefs throughout the Caribbean Sea since the Pleistocene. Beginning in the 1980s A. palmata has declined to a small fraction of its formerly vast extent throughout the region. In 2006, elkhorn coral was the first coral, along with its sister species, staghorn coral (Acropora cervicornis), to be included on the U.S. Endangered Species List. We used size-based matrix modeling to parameterize annual A. palmata population dynamics in Florida, over the course of one severe hurricane year (2005) and six calm years (2004, and 2006-2010), incorporating environmental stochasticity as inter-annual variability. We predicted that benthic cover would remain at current levels (4%) for the foreseeable future (until 2030) and beyond (until 2100), suggesting a lack of resilience following the 2005 hurricanes. Standard metrics for the quantification of number and size of individuals are essential to endangered species management. These usually straightforward tasks can be challenging for clonal, colonial organisms. Acropora palmata presents a particular challenge due to its plastic morphology and frequent fission. We quantified three-dimensional colony surface area (CSA), the most ecologically relevant measure of size, for 14 prototypically arborescent A. palmata colonies using three-dimensional digital imaging software. To relate CSA to simple field metrics, we compared log-likelihood values and determined that planar projection was the best predictor. The, tight, linear relationship between planar projection and CSA enables ecological rates, such as reef accretion and gamete production, to be calculated from field data. Finally, we expanded the matrix population model to compare population dynamics in several locations across the Caribbean. The general trend for Acropora palmata is further reductions in population size by 2030. The most striking difference we quantified was between Jamaica, where population size is projected to increase, and all other locations, where population size is projected to remain stable or decline. Density of a key herbivore, the sea urchin Diadema antillarum, was an order of magnitude greater in Jamaica than in any other location. These increases are occurring 30 years after a devastating die-off suggesting that herbivory by urchins may facilitate A. palmata recovery.

Book Description
"The overall goal of the Endangered Species Act (ESA) is to provide a means by which endangered and threatened species and the ecosystems upon which they depend may be conserved. To help achieve this goal, the ESA requires the preparation of a recovery plan for each listed species unless such a plan will not promote its conservation. Recovery plans guide the implementation of actions required to recover listed species to the point at which they are self-sustainable in the wild and can be safely removed from the list of endangered and threatened species. Recovery plans are advisory documents only, and their recommendations are not obligatory. However, failure to implement recovery actions may result in the indefinite listing of the species or its extinction. This recovery plan covers both elkhorn (Acropora palmata) and staghorn (A. Cervicornis) corals, which the National Marine Fisheries Service (NMFS) listed as threatened under the ESA in May 2006"--Background.

Book Description
The Law Library presents the complete text of the Endangered and Threatened Species - Final Listing Determinations for Elkhorn Coral and Staghorn Coral (US National Oceanic and Atmospheric Administration Regulation) (NOAA) (2018 Edition). Updated as of May 29, 2018 We, the National Marine Fisheries Service (NMFS), are publishing this final rule to implement our determination to list elkhorn (Acropora palmata) and staghorn (A. cervicornis) corals as threatened species under the Endangered Species Act (ESA) of 1973, as amended. We have reviewed the status of the species and efforts being made to protect the species, and we have made our determinations based on the best scientific and commercial data available. We also solicit information that may be relevant to our analysis of protective regulations and to the designation of critical habitat for these two species. This ebook contains: - The complete text of the Endangered and Threatened Species - Final Listing Determinations for Elkhorn Coral and Staghorn Coral (US National Oceanic and Atmospheric Administration Regulation) (NOAA) (2018 Edition) - A dynamic table of content linking to each section - A table of contents in introduction presenting a general overview of the structure
