  • isolation and characterization of 14 polymorphic microsatellite loci in the leatherback turtle dermochelys coriacea and cross species amplification
    Conservation Genetics Resources, 2011
    Co-Authors: Suzanne E Roden, Peter H. Dutton
    Abstract:

    Fourteen microsatellites were isolated and characterized from a small-insert genomic DNA library from the leatherback turtle Dermochelys coriacea enriched for dinucleotide microsatellite motifs. We tested primers on 207 leatherbacks sampled from St. Croix, US Virgin Islands. Primer pairs yielded an average of 5.7 alleles per locus, an average observed heterozygosity of 0.47, and average polymorphic information content of 0.43. Cross species amplification of these markers was performed on the six other extant species of marine turtles: olive ridley (Lepidochelys olivacea), Kemp’s ridley (Lepidochelys kempii), hawksbill (Eretmochelys imbricata), loggerhead (Caretta caretta), green (Chelonia mydas), and flatback (Natator depressus) turtles. Eleven of the markers worked in at least one of the species, and seven of these were polymorphic. These leatherback-specific microsatellite markers will facilitate population genetic and ecological studies to aid in the conservation of this divergent species of marine turtle, and provide additional markers for the other species of cheloniids.

  • Forage and migration habitat of loggerhead (Caretta caretta) and olive ridley (Lepidochelys olivacea) sea turtles in the central North Pacific Ocean
    Fisheries Oceanography, 2004
    Co-Authors: Jeffrey J. Polovina, George H. Balazs, Evan A. Howell, Denise M. Parker, Michael P. Seki, Peter H. Dutton
    Abstract:

    Satellite telemetry from 26 loggerhead (Caretta caretta) and 10 olive ridley (Lepidochelys olivacea) sea turtles captured and released from pelagic longline fishing gear provided information on the turtles’ position and movement in the central North Pacific. These data together with environmental data from satellite remote sensing are used to describe the oceanic habitat used by these turtles. The results indicate that loggerheads travel westward, move seasonally north and south primarily through the region 28–40°N, and occupy sea surface temperatures (SST) of 15–25°C. Their dive depth distribution indicated that they spend 40% of their time at the surface and 90% of their time at depths

  • Disseminated Mycotic Infection Caused by Colletotrichum acutatum in a Kemp's Ridley Sea Turtle (Lepidochelys kempi)
    Journal of clinical microbiology, 2002
    Co-Authors: Charles A. Manire, Howard L. Rhinehart, Deanna A. Sutton, Elizabeth H. Thompson, Michael G. Rinaldi, John D. Buck, Elliott R Jacobson
    Abstract:

    Colletotrichum acutatum is a cosmopolitan plant pathogen with a wide host range. While the organism's phytopathogenic potential has been well documented, it has never been reported as an etiologic agent of disease in either animals or humans. In this case, a juvenile Kemp's ridley sea turtle, Lepidochelys kempi, probably with immune compromise following cold stunning (extended hypothermia), developed a disseminated mycotic infection in the lungs and kidneys. Prophylactic treatment with oral itraconazole did not prevent or cure the infection. This report of a Colletotrichum acutatum infection in an animal extends the range of disease caused by this organism beyond that of a phytopathogen.

  • Immunological competence in the green turtle and itsrelationship to the development of fibropapilloma disease
    1997
    Co-Authors: Elliott R Jacobson, Ellis C. Greiner
    Abstract:

    Fibropapillomatosis (FP) remains a growing threat to the survival of sea turtles in Florida and other locations worldwide. FP has seriously affected green turtle, Chelonia mydas, populations in Florida and Hawaii and is now emerging as a significant threat to the loggerhead, Caretta caretta, in Florida. In addition the disease has been reported in olive ridley, Lepidochelys olivacea, populations as well. Data from several field studies suggests that high FP prevalence is associated with marine ecosystems impacted by human activities, including agricultural, industrial, and urban development although the exact role of environmental co-factors is unclear.

  • pengamatan kesesuaian lahan peneluran penyu lekang Lepidochelys olivacea eschscholtz 1829 reptilia cheloniidae di pantai mapak indah nusa tenggara barat
    Journal of Marine Research, 2020
    Co-Authors: Mochamad Rizaldi Akbar, Oktiyas Muzaky Luthfi, M Barmawi
    Abstract:

    ABS TRAK : Pantai Mapak Indah merupakan pantai yang sering menjadi pantai pendaratan biota Penyu, umumnya penyu yang mendarat berjenis penyu Lekang (Lepidochelys olivaceae), pantai yang juga di gunakan untuk aktifitas nelayan dan pariwisata diduga akan mengganggu habitat penyu yang cenderung merusak atau merubahnya. Tujuan dari penelitian ini adalah untuk mengetahui habitat yang sesuai untuk kebutuhan peneluran penyu Lekang (Lepidochelys olivaceae). Metode yang di pakai menggunakan data Primer (Suhu, Kelembaban, Kemiringan, dan Vegetasi) dan skunder berasal dari catatan kelompok pelestari penyu dan instansi terkait. Penelitian ini di laksanakan pada tanggal 24 Juni – 05 Agustus 2019. Hasil dari penelitan ini adalah rentang kemiringan pantai mencapai 10.5%-26% dengan rata-rata 16.3% masih dalam kategori Agak Curam, untuk perbandingan komposisi pasir di sarang Alami dan Semi-Alami 92,94% & 96,34%, vegetasi yang di temukan di sekitar pantai adalah cemara Udang ( Casuarina Equisetifolia ) dan Pandan Laut ( Pandanus sp.), kelapa ( Cocos Nucifera ) dan Katang-katang ( Ipomoea pes-caprae ). Suhu saat di lakukan pengamatan selama seminggu memiliki rentang 25°-28° hal ini dapat mempengaruhi jenis kelamin Tukik yang akan menetas serta lama inkubasinya di dalam sarang Semi-Alami ABS TRACT: Mapak Indah Beach is a beach that is often used as a landing site for sea turtles, generally turtles that land on the type of Lekang turtle (Lepidochelys olivaceae), a beach that is also used for fishing and tourism activities is thought to disturb turtle habitats that tend to damage or change it. The purpose of this study was to determine the suitable habitat for the needs of Lekang turtle nesting (Lepidochelys olivaceae). The method used uses Primary data (Temperature, Humidity, Slope, and Vegetation) and secondary data derived from the records of turtle conservation groups and related agencies. This research was carried out on 24 June - 05 August 2019. The results of this research are the range of beach slopes reaching 10.5% -26% with an average of 16.3% still in the category of somewhat steep, for comparison of sand composition in natural and semi-natural nests 92.94% & 96.34%, vegetation found around the coast is pine shrimp (Casuarina Equisetifolia) and Pandan Laut (Pandanus sp.), Coconuts (Cocos Nucifera) and Katang-Katang (Ipomoea pes-caprae). Temperature when observed for a week has a range of 25 ° -28 ° this can affect the sex of the hatchlings that will hatch and the length of incubation in the Semi-Natural nest
