 Heavy Metals Contaminants In The Eggs And Temperatures Of Nesting Beaches Of Sea Turtles In Kaimana, West Papua, Indonesia | 1600217206 Author(s): RICARDO F. TAPILATU, HENGKI WONA, RIMA HS. SIBURIAN, and SEFRIANTO T. SALEDA Tags: Description: Biodiversitas 21: 4582-4590. Etna Bay and Venu Island in Kaimana, West Papua, Indonesia are two of many areas that sea turtles use during the nesting season. Here, we report data on heavy metals contaminants from a sample of eggs of green (Chelonia mydas) and hawksbill (Eretmochelys imbricata) turtles collected from a subset of two nests during the 2016 nesting season at Venu Island, Kaimana, West Papua, Indonesia. Three heavy metals contaminants (i.e. mercury, cadmium, arsenic) found in eggs exceeded the established safety limits for human consumption. 0.9 MiB | 41 |
 Recognizing Peripheral Ecosystems In Marine Protected Areas: A Case Study Of Golden Jellyfish Lakes in Raja Ampat, Indonesia | 1600215832 Author(s): Diede L. Maas, Agustin Capriati, Awaludinnoer Ahmad, Mark V. Erdmann, Machiel Lamers, Christiaan A. de Leeuw, Luca Prins, Purwanto, Amanda P. Putri, Ricardo F. Tapilatu, Leontine E. Becking Tags: Description: Peripheral marine ecosystems can harbor endemic diversity and attract tourism attention, yet are generally not included in conservation management plans due to their remoteness or inland positioning. A case study in Raja Ampat of seven landlocked marine lakes containing golden jellyfish (Mastigias spp.) was conducted to address the lack of fundamental insights into evolutionary, ecological and social contexts of these ecosystems. An interdisciplinary approach was taken towards identifying the jellyfish lakes as distinct management units in order to incorporate them into existing Marine Protected Areas. Mastigias papua populations showed strong genetic (ϕST: 0.30–0.86) and morphological (F = 28.62, p-value = 0.001) structure among lakes, with putative new subspecies. Risks arising from rapid increase in tourism to Raja Ampat (30-fold since 2007) warrant restrictions on jellyfish lake use. Recommendations are provided for adaptive management and science-based conservation policies for jellyfish lakes across Indonesia. 1.0 MiB | 26 |
 Recognizing peripheral ecosystems in marine protected areas: A case study T of golden jellyfish lakes in Raja Ampat, Indonesia | 1596666229 Author(s): Diede L. Maas, Agustin Capriati, Awaludinnoer Ahmad, Mark V. Erdmann, Machiel Lamers, Christiaan A. de Leeuw, Luca Prins, Purwanto, Amanda P. Putria, Ricardo F. Tapilatu, Leontine E. Beckinga Tags: Description: Peripheral marine ecosystems - such as marine lakes, anchialine caves, and cenotes - attract significant attention from tourism due to their relatively pristine environments and propensity to harbor endemic diversity. Tourism interest can have socio-economic benefits for local communities, can lead to an awareness towards management of the ecosystem and prevent de- structive exploitation. However, if tourism is not managed effectively, recreational use of peripheral marine ecosystems may have devastating effects, particu- larly in combination with other stressors such as climate change. Prime examples of peripheral ecosystems that are tourism magnets are “jellyfish lakes”, landlocked marine lakes containing dense populations of golden jellyfish, Mastigias spp. 1.7 MiB | 40 |
 Movement patterns of whale sharks in Cenderawasih Bay, Indonesia, revealed through long-term satellite tagging | 1596666053 Author(s): Megan M. Meyers, Malcolm P. Francis, Mark Erdmann, Rochelle Constantine and Abraham Sianipar Tags: Description: The world’s largest fish, the whale shark, Rhincodon typus, is a highly mobile species that occurs in tropical and warm temperate seas worldwide (Rowat and Brooks 2012). Whale sharks, Rhincodon typus, are found circumglobally in tropical and warm temperate seas, exhibiting a range of residency and movement patterns. To determine spatio-temporal habitat use by juvenile male whale sharks in Cenderawasih Bay, Indonesia, we collected data from June 2015 to November 2016 using 16 fin-mounted satellite tags that provided exceptionally long track durations. 1.2 MiB | 90 |

 Patterns of species richness and the center of diversity in modern Indo- Pacific larger foraminifera | 1566602303 Author(s): Meena Förderer, Dennis Rödder & Martin R. Langer Tags: Description: Symbiont-bearing Larger Benthic Foraminifera (LBF) are ubiquitous components of shallow tropical and subtropical environments and contribute substantially to carbonaceous reef and shelf sediments. Climate change is dramatically affecting carbonate producing organisms and threatens the diversity and structural integrity of coral reef ecosystems. Recent invertebrate and vertebrate surveys have identified the Coral Triangle as the planet’s richest center of marine life delineating the region as a top priority for conservation. We compiled and analyzed.... 1.9 MiB | 138 |
 Status of sea turtle populations and its conservation at Bird’s Head Seascape, Western Papua, Indonesia | 1499803740 Author(s): Ricardo Tapilatu, Hengki Wona, Petrus Batubara Tags: Description: Bird’s Head Seascape region in the northwest of Papua contains the world’s highest marine biodiversity. The area is a unique site which contains a full range of marine and coastal habitats that are important for the breeding, foraging and migration of several species of sea turtles. This survey aimed to characterize critical habitats that are in use by sea turtles across Yapen, Wondama, Manokwari and Kaimana at Bird’s Head Seascape and to assess existing and potential threats to both habitats and population. 0.4 MiB | 840 |
 Penentuan Daerah Konservasi Laut Berdasarkan Informasi Suhu Permukaan Laut | 1394662607 Author(s): Gandi Purba Tags: kawasan konservasi, Teluk Cendrawasih, suhu permukaan laut Description: Terumbu karang adalah salah satu ekosistem penting di wilayah pesisir. Ancaman kepunahan skala besar yang disebabkan oleh pemanasan suhu global menambah kecemasan setelah kerusakan yang dilakukan manusia. Suhu sebagai syarat hidup utama karang, kenaikannya akan menyebabkan pemutihan yang pada akhirnya akan mati karena ketidakmampuan karang untuk beradaptasi. Menurut laporan NOAA Coral Reef Watch (CRW), khusus di Perairan Papua bagian utara, di tahun 1998 yang merupakan tahun terkuat fenomena ELNINO, kenaikan suhu di sekitar Kepala Burung mencapai 20C dan Teluk Cendrawasih 10C (http://coralreefwatch.noaa.gov/satellite). Apabila peningkatan 1°C saja bertahan selama 10 minggu atau lebih, maka pemutihan pasti terjadi. 0.2 MiB | 701 |
 Excerpt On Sea Surface Temperature Monitoring From Final BHS EBM II Report | 1394662301 Author(s): Mark Erdmann; Gandi Purba Tags: MPA, BHS, sea surface temperature, climate change, monitoring, coral bleaching Description: Sea Surface Temperature (SST) is one of the primary oceanographic factors controlling the development and growth of coral reefs. Significant variances in SST (such as those predicted as a consequence of global climate change) are known to cause significant stress, coral bleaching, and even mass mortality in reef corals....By continuing this SST monitoring, we can measure long-term trends in the SST pattern as well as the impact of El Niño and La Niña events, which have been associated with mass coral bleaching, on SST in the BHS. In addition, we plan to transfer the dataset and monitoring program to the State University of Papua in Manokwari (UNIPA) as a capacity-building initiative. 89 KiB | 755 |
 Ketahanan Karang Menghadapi Kenaikan Suhu Permukaan Laut Guna Penentuan Kawasan Konservasi Laut Di Teluk Cendrawasih | 1393962472 Author(s): Gandi Purba; Roni Bawole; MV Erdmann; Chris Rotinsulu; Erdi Lazuardi; Thomas Pattiasina Tags: kawasan konservasi, Teluk Cendrawasih, suhu permukaan laut, ketahanan karang Description: Berbagai upaya pengelolaan terumbu karang yang telah dilakukan oleh beberapa lembaga internasional maupun nasional. Bahkan pada skala lokal (pemerintah daerah) telah menetapkan Kawasan Konservasi Laut (KKL) untuk menjamin pemanfaatan yang lestari terhadap sumberdaya karang. Namun demikian upaya tersebut belum memberikan hasil maksimal karena penetapan lokasi KKL masih dilakukan secara konvensional berdasarkan kriteria ekologis (karang yang sehat), sosek, kelembagaan dan peraturan perundangan yang berlaku, serta aspek budaya masyarakat. Pendekatan-pendekatan ini tidak selamanya berhasil dalam jangka panjang karena lokasi-lokasi KKL pada beberapa tempat karangnya secara alamiah telah mengalami kerusakan, misalnya Kepulauan Padaido, Raja Ampat, Takabonerate, dan lain-lain. Para pencetus KKL saat itu belum menganggap efek Pemanasan Global sebagai gejala universal yang harus dicermati dan faktor yang dapat menghancurkan karang pada lokasi-lokasi KKL. Pengaruh Pemanasan Global ini telah mendorong kenaikan Suhu Permukaan Laut (SPL) yang pada tahap berikut bersifat mematikan karang akibat terganggunya simbiosis mutualisme karang – zooxanthellae. 0.1 MiB | 2095 |
