Available in PDF, EPUB and Kindle. Book excerpt: As both individuals and societies, we are making decisions today that will have profound consequences for future generations. From preserving Earth's plants and animals to altering our use of fossil fuels, none of these decisions can be made wisely without a thorough understanding of life's history on our planet through biological evolution. Companion to the best selling title Teaching About Evolution and the Nature of Science, Evolution in Hawaii examines evolution and the nature of science by looking at a specific part of the world. Tracing the evolutionary pathways in Hawaii, we are able to draw powerful conclusions about evolution's occurrence, mechanisms, and courses. This practical book has been specifically designed to give teachers and their students an opportunity to gain a deeper understanding of evolution using exercises with real genetic data to explore and investigate speciation and the probable order in which speciation occurred based on the ages of the Hawaiian Islands. By focusing on one set of islands, this book illuminates the general principles of evolutionary biology and demonstrate how ongoing research will continue to expand our knowledge of the natural world.

Download or read book Encyclopedia of Modern Coral Reefs written by David Hopley and published by Springer Science & Business Media. This book was released on 2010-11-26 with total page 1226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coral reefs are the largest landforms built by plants and animals. Their study therefore incorporates a wide range of disciplines. This encyclopedia approaches coral reefs from an earth science perspective, concentrating especially on modern reefs. Currently coral reefs are under high stress, most prominently from climate change with changes to water temperature, sea level and ocean acidification particularly damaging. Modern reefs have evolved through the massive environmental changes of the Quaternary with long periods of exposure during glacially lowered sea level periods and short periods of interglacial growth. The entries in this encyclopedia condense the large amount of work carried out since Charles Darwin first attempted to understand reef evolution. Leading authorities from many countries have contributed to the entries covering areas of geology, geography and ecology, providing comprehensive access to the most up-to-date research on the structure, form and processes operating on Quaternary coral reefs.

Download or read book Community Structure of Hermatypic Corals at Kure Atoll in the Northwestern Hawaiian Islands written by Jean C. Kenyon and published by . This book was released on 2008 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: The distribution and abundance of scleractinian corals at Kure Atoll in the Northwestern Hawaiian Islands was determined by georeferenced towed-diver surveys that covered close to 27,000 m2 of benthic habitat and site-specific surveys at 21 sites during 2000-2003. Three complementary methods (towed-diver surveys, video transects, and photoquadrats) were used to quantify percent cover of corals by genus or species in the fore-reef, back-reef, and lagoon habitats. Three genera, Porites, Pocillopora, and Montipora, accounted for more than 99% of the coral cover throughout the atoll, although their relative abundances vary considerably according to habitat and geographic sector within habitats. Fore-reef communities are dominated by massive and encrusting Porites and by Pocillopora, while the back reef is dominated by Montipora and the lagoon by Porites compressa. All taxa show habitat-specific differences in colony density and size-class distributions as assessed through colony counts within belt transects at fixed sites. These demographic data provide the most detailed, spatially comprehensive description of coral communities at Kure Atoll produced to date and can serve as a solid baseline for determining the magnitude and direction of future changes. They are discussed within the context of factors known to affect community development on Hawaiian coral reefs including temperature, wave stress, coral bleaching and other diseases, marine debris, and crown-of-thorns seastars.

This book was released on 2006 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This project summarizes the current status of the Hawaiian black coral fishery and compares results with historical measurements. To achieve this, historical methodology where possible was used to make comparisons as similar as possible. The goals and objectives of this project included: 1) measure black coral colonies to determine the current age structure, 2) collect samples to measure genetic relatedness of black corals across the Main Hawaiian Islands to address possible distinct populations, 3) measure the density of black coral colonies in the areas sampled for population structure, 4) determine the growth rate and compare with the historically determined growth rate for the targeted species, and 5) develop a draft management plan based on all available information (new and historical)"--Abstract.

This book was released on 2013 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This capacity assessment is a component of the coral reef management priority setting process facilitated by the National Oceanic and Atmospheric Administration's Coral Reef Conservation Program (NOAA CRCP) and initiated in 2009. The stated purpose of this process was "to develop place-based, local coral reef management priorities" for the seven United States (U.S.)state and territorial coral reef jurisdictions, including Hawaii. In Hawaii, the priorities in the 2010 publication of Hawaiian Archipelago' Coral Reef Management Priorities (henceforth, the "Priority Setting Document," or "PSD") were largely created in support of the ongoing development of the Hawaii Coral Reef Strategy: Priorities for Management in the Main Hawaiian Islands 2010-2020 (henceforth, the "Strategy") and The Papahānaumokuākea Marine National Monument Management Plan. Given that, the Strategy was the main lens for the capacity assessment process. For the purposes of this assessment, our scope included exclusively the Main Hawaiian Islands (also referred to as Hawaii and State of Hawaii as distinctive terms that are more appropriate in a given context). The Strategy includes, in Section 6, a brief summary of governance capacity issues in Hawaii entitled "Capacity Gaps." In this section, the Strategy states that, "The HCRS [the Strategy] cannot be implemented effectively without addressing capacity gaps in coral reef management." In September 2011, NOAA CRCP hired SustainaMetrix to conduct a more detailed assessment across all seven coral jurisdictions including Hawaii, which expands on this initial effort to address capacity gaps in ecosystem governance for coral reef management in Hawaii. This report summarizes the findings of our capacity assessment conducted in Hawaii between September 2012 and April 2013, including a 14-day site visit to Hawaii from November 26 to December 10, 2012, the review of over 140 background documents, over 65 interviews, and ongoing collaboration with the Hawaii Jurisdictional Capacity Assessment Team (J-CAT)"--Page 14 (Introduction).

Download or read book Radiocarbon Based Ages and Growth Rates written by and published by . This book was released on 2006 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: The radial growth rates and ages of three different groups of Hawaiian deep-sea 'corals' were determined using radiocarbon measurements. Specimens of Corallium secundum, Gerardia sp., and Leiopathes glaberrima, were collected from 450 ± 40 m at the Makapuu deep-sea coral bed using a submersible (PISCES V). Specimens of Antipathes dichotoma were collected at 50 m off Lahaina, Maui. The primary source of carbon to the calcitic C. secundum skeleton is in situ dissolved inorganic carbon (DIC). Using bomb 14C time markers we calculate radial growth rates of H"170 [mu]m y−1 and ages of 68-75 years on specimens as tall as 28 cm of C. secundum. Gerardia sp., A. dichotoma, and L. glaberrima have proteinaceous skeletons and labile particulate organic carbon (POC) is their primary source of architectural carbon. Using 14C we calculate a radial growth rate of 15 [mu]m y−1 and an age of 807 ± 30 years for a live collected Gerardia sp., showing that these organisms are extremely long lived. Inner and outer 14C measurements on four sub-fossil Gerardia spp. samples produce similar growth rate estimates (range 14-45 [mu]m y−1) and ages (range 450-2742 years) as observed for the live collected sample. Similarly, with a growth rate of

Download or read book Biogeochemistry and Physiology of Bleached and Recovering Hawaiian and Caribbean Corals written by Stephen J. Levas and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Coral reefs are declining globally due to a combination of direct and indirect human impacts. Much of this decline can be attributed to prolonged exposure to elevated sea surface temperatures which induces coral bleaching - a process whereby corals lose their endosymbionts and/or their endosymbiotic pigments resulting in corals that appear pale or white. Corals have extremely different responses to bleaching events: some corals bleach and die, others bleach and recover, and some do not visibly bleach at all. In the absence of abundant photosynthetically fixed C, corals may rely on one or more of the following strategies to sustain themselves and promote recovery: (1) catabolize stored energy reserves, including lipids, carbohydrates, and/or proteins, (2) reduce respiration rates, (3) decrease skeletal growth, (4) increase heterotrophy or (5) shuffle or change their endosymbiont type(s). Although mounding species of coral have been shown to survive bleaching events in greater abundance than branching species, the underlying mechanism(s) for mounding coral resilience is unknown. Furthermore, controlled bleaching and recovery experiments coupled with detailed carbon budgets that incorporate autotrophy and multiple heterotrophic sources (i.e. zooplankton and dissolved organic carbon) do not exist for Caribbean corals. Therefore, two controlled tank experiments, one in Hawaii and the other in Puerto Morelos, Mexico were conducted to understand the bleaching and recovery responses in the Hawaiian coral Porites lobata and the three Caribbean corals Montastraea faveolata, Porites astreoides, and Porites divaricata. Four major findings were observed: 1) Bleaching resilience in the mounding coral P. lobata is due to it harboring a thermally tolerant endosymbiont type combined with an ability to actively metabolize zooplankton acquired C and utilize DOC as a significant fixed C source, 2) Bleached P. astreoides were capable of meeting greater than 100% of metabolic demand by increasing feeding rates, 3) All Caribbean corals took up dissolved organic carbon as a source of fixed carbon when bleached, 4) M. faveolata and P. astreoides are more resilient to single bleaching than P. divaricata. This study represents the first comprehensive assessment of the underlying traits that confer bleaching resilience in a mounding Hawaiian coral. Furthermore, these studies represent a comprehensive physiological and biogeochemical analysis of bleached and recovering Caribbean corals and the first to detail their carbon budgets. The ability for bleached corals to maintain high photosynthetic capacity coupled with the ability to utilize exogenous C sources appears to be an underlying theme in resilience to bleaching. Based on these findings, species such as P. lobata, M. faveolata, and to a lesser extent P. astreoides are more likely to survive a single bleaching event than the branching P. divaricata or the previously studied branching coral P. compressa.
