Reserva Natural del Corredor Ecológico del Noreste Ley Núm. 126 de 25 de junio de 2012 Para establecer la "Ley de la Gran Reserva Natural del Corredor Ecológico del Noreste", a los fines de declarar y designar como reserva natural todo terreno público y patrimonial perteneciente a cualquier agencia, corporación pública o instrumentalidad del Gobierno de Puerto Rico en el área denominada como "Corredor Ecológico del Noreste", el cual ubica en la costa de los municipios de Luquillo y Fajardo; para establecer como política pública la preservación, restauración y conservación de dicha área; y para otros fines relacionados. EXPOSICION DE MOTIVOS Puerto Rico cuenta solamente con un 8% de su territorio terrestre dedicado a la preservación y conservación. Esta área incluye propiedades públicas y privadas clasificadas como bosques estatales, bosques federales nacionales, refugios de vida silvestre, reservas naturales, áreas naturales protegidas, servidumbres de conservación, y terrenos adquiridos o manejados por el Gobierno Estatal, Federal y organizaciones conservacionistas no gubernamentales. Este porcentaje es significativamente inferior a otras jurisdicciones vecinas, tales como la República Dominicana (42%), Cuba (32%), las Islas Vírgenes Americanas (54%), el Caribe (28.2%), los Estados Unidos (25%), así como el promedio de 15% estimado para países desarrollados. La falta de protección de una extensión mayor de terrenos pone en precario los servicios ecológicos asociados a la provisión y calidad de agua potable, la calidad del aire, poblaciones de flora y fauna silvestre y hábitats saludables, seguridad ciudadana, suelos productivos, reservas genéticas, oportunidades recreacionales y turísticas, y refugio espiritual, todos indispensables para garantizar el desarrollo sostenible de Puerto Rico. El Departamento de Recursos Naturales y Ambientales (DRNA), la Administración Nacional Oceánica y Atmosférica (“NOAA”, por sus siglas en inglés), el Servicio de Pesca y Vida Silvestre de los Estados Unidos (“USFWS”, por sus siglas en inglés), y el Servicio Forestal Federal (“USFS”, por sus siglas en inglés), han realizado numerosos esfuerzos para identificar aquellos terrenos en Puerto Rico, cuya preservación y conservación debe ser prioritaria debido a su extraordinario valor natural. Por más de Pág. 5 tres décadas, el Corredor Ecológico del Noreste (CEN) ha sido reconocido por éstas y otras agencias, así como por organizaciones conservacionistas locales e internacionales, como una de las áreas de mayor valor natural en Puerto Rico. El CEN consiste de aproximadamente 3,057 cuerdas (1,202 ha) ubicadas en la costa de los municipios de Luquillo y Fajardo. Cerca de 2,931 cuerdas (1,152 ha) son terrenos firmes y anegados, y 126 cuerdas (50 ha) corresponden a cuerpos de agua superficiales. El CEN está integrado principalmente por las fincas San Miguel I y II, Las Paulinas, El Convento Norte y Sur, y Seven Seas. Un 65.9% del área del Corredor corresponde a terrenos públicos y patrimoniales pertenecientes a diversas dependencias gubernamentales. La Compañía de Fomento Industrial administra aproximadamente 1,276.73 cuerdas como parte de las fincas Las Paulinas y El Convento Norte. La Compañía de Parques Nacionales es dueña de 110 cuerdas designadas

Santa Marta. Colombia. * [email protected] Recibido: 28-02-2011; Aceptado: 11-05-2011 Abstract Recruitment, defined and measured as the incorporation of new individuals (i.e. coral juveniles) into a population, is a fundamental process for ecologists, evolutionists and conservationists due to its direct effect on population structure and function. Because most coral populations are self-feeding, a breakdown in recruitment would lead to local extinction. Recruitment indirectly affects both renewal and maintenance of existing and future coral communities, coral reef biodiversity (bottom-up effect) and therefore coral reef resilience. This process has been used as an indirect measure of individual reproductive success (fitness) and is the final stage of larval dispersal leading to population connectivity. As a result, recruitment has been proposed as an indicator of coral-reef health in marine protected areas, as well as a central aspect of the decision-making process concerning management and conservation.

ABSTRACT - In the Werlberg Member (Rupelian pro parte) of the Paisslberg Formation (Eastern Alps), an assemblage of colonial corals of eleven species pertaining to eleven genera and eleven families was identified:Stylocoenia carryensis, Acropora lavandulina, ?Colpophyllia sp., Dendrogyra intermedia, Caulastraea pseudoflabellum, Hydnophyllia costata, Pindosmilia cf. brunni, Actinacis rollei, Pavona profunda, Agathiphyllia gregaria, and Faksephyllia faxoensis. This is the first Oligocene coral assemblage reported from the Paisslberg Formation (Werlberg Member) of the Eastern Alps, consisting exclusively of colonial forms. The assemblage represents the northernmost fauna of reefal corals reported to date for Rupelian time. The Werlberg Member accumulated during marine transgression onto a truncated succession of older carbonate rocks. The corals grew as isolated colonies and in carpets in a protected shoreface setting punctuated by high-energy events. Coral growth forms comprise massive to sublamellar forms, and branched (dendroid, ramose) forms.

  • The Earliest Diverging Extant Scleractinian Corals Recovered by Mitochondrial Genomes Isabela G
    www.nature.com/scientificreports OPEN The earliest diverging extant scleractinian corals recovered by mitochondrial genomes Isabela G. L. Seiblitz1,2*, Kátia C. C. Capel2, Jarosław Stolarski3, Zheng Bin Randolph Quek4, Danwei Huang4,5 & Marcelo V. Kitahara1,2 Evolutionary reconstructions of scleractinian corals have a discrepant proportion of zooxanthellate reef-building species in relation to their azooxanthellate deep-sea counterparts. In particular, the earliest diverging “Basal” lineage remains poorly studied compared to “Robust” and “Complex” corals. The lack of data from corals other than reef-building species impairs a broader understanding of scleractinian evolution. Here, based on complete mitogenomes, the early onset of azooxanthellate corals is explored focusing on one of the most morphologically distinct families, Micrabaciidae. Sequenced on both Illumina and Sanger platforms, mitogenomes of four micrabaciids range from 19,048 to 19,542 bp and have gene content and order similar to the majority of scleractinians. Phylogenies containing all mitochondrial genes confrm the monophyly of Micrabaciidae as a sister group to the rest of Scleractinia. This topology not only corroborates the hypothesis of a solitary and azooxanthellate ancestor for the order, but also agrees with the unique skeletal microstructure previously found in the family. Moreover, the early-diverging position of micrabaciids followed by gardineriids reinforces the previously observed macromorphological similarities between micrabaciids and Corallimorpharia as

FOOD HABITS OF NORTHERN BAHAMIAN ROCK IGUANAS (CYCLURA CYCHLURA) IN THE EXUMA ISLANDS, WITH A DIETARY REVIEW OF ROCK IGUANAS (GENUS CYCLURA) KIRSTEN N. HINES 3109 Grand Ave #619, Coconut Grove, Florida 33133, USA e-mail: [email protected] Abstract.—This study examined the natural diet of Northern Bahamian Rock Iguanas (Cyclura cychlura) in the Exuma Islands. The diet of Cyclura cychlura in the Exumas, based on fecal samples (scat), encompassed 74 food items, mainly plants but also animal matter, algae, soil, and rocks. This diet can be characterized overall as diverse. However, within this otherwise broad diet, only nine plant species occurred in more than 5% of the samples, indicating that the iguanas concentrate feeding on a relatively narrow core diet. These nine core foods were widely represented in the samples across years, seasons, and islands. A greater variety of plants were consumed in the dry season than in the wet season. There were significant differences in parts of plants eaten in dry season versus wet season for six of the nine core plants. Animal matter occurred in nearly 7% of samples. Supported by observations of active hunting, this result suggests that consumption of animal matter may be more important than previously appreciated. A synthesis of published information on food habits suggests that these results apply generally to all extant Cyclura species, although differing in composition of core and overall diets. Key Words.—Bahamas; Caribbean; carnivory; diet; herbivory; predation; West Indian Rock Iguanas INTRODUCTION versus food eaten in unaffected areas on the same island, finding differences in both diet and behavior (Hines Northern Bahamian Rock Iguanas (Cyclura cychlura) 2011).
