Climate-driven Global Redistribution of an Ocean Giant Predicts Increased Threat from Shipping 1733174219
Author(s): Womersley, F.C., Sousa, L.L., Humphries, N.E. et al.
Tags: whale sharks, Climate Change Oceanography, Climate Change Impacts, Conservation Biology
Description: Climate change is shifting animal distributions. However, the extent to which future global habitats of threatened marine megafauna will overlap existing human threats remains unresolved. Here we use global climate models and habitat suitability estimated from long-term satellite-tracking data of the world’s largest fish, the whale shark, to show that redistributions of present-day habitats are projected to increase the species’ co-occurrence with global shipping

Islands of Sea: The evolution, ecology and conservation of marine lake invertebrates 1632165844
Author(s): Diede Louise Maas
Tags: marine lakes
Description: A major question of ecologists and evolutionary biologists is how biodiversity arises and how
it is maintained. Biodiversity is multifaceted, and genetic diversity within populations is one
of its components besides species and ecosystem diversity (Vellend and Geber, 2005).
Thesis on evolution, ecology, and conservation of marine lake invertebrates.
Studies of microevolution focus on intra-specific variation within populations which
eventually might lead to the macroevolutionary process of speciation (Hendry et al., 2009).
Genetic diversity within populations is usually measured via allele frequencies, or the
number of times a variant of a gene occurs in a population. Allele frequencies can change
due to mutation, selection, gene flow (migration between populations) and genetic drift
(stochastic loss or gain of alleles). The fields of population genetics and genomics aim to
improve our understanding of population differentiation (Charlesworth, 2010; Luikart et al.,
2018), by questioning how spatial and environmental factors influence microevolutionary
processes. Microevolutionary studies in marine systems are lagging behind terrestrial
counterparts for several reasons (Selkoe et al., 2008, 2016), first and foremost being the
difficulty to access many marine areas. Furthermore, there is a long-standing assumption
that marine populations show low rates of genetic differentiation due to the lack of clear
physical barriers, assumed high dispersal potential, and associated large effective
population sizes (Palumbi, 1994; Ward, 1994; Bowen et al., 2013). While this assumption
has both been confirmed and rejected for different organisms (Bierne et al., 2016), in any
case the open nature of the marine realm makes defining marine populations a priori
challenging. Still, recent studies are showing more population structure in marine
ecosystems and at finer spatial scales (1-100kms) than expected by predicted larval
dispersal distances (Hauser and Carvalho, 2008; Marshall et al., 2010; Van Wyngaarden et
al., 2016; Bernatchez et al., 2018). Further elucidating marine population genetic patterns
on small scales and shedding light on what drives marine population connectivity and
adaptation is particularly pressing in a changing world. This thesis aims to disentangle
relative importance of neutral (geographic and dispersal barriers) and selective (local
adaptation) processes on marine population genomic variation using the unique opportunity
presented by marine lakes which offer replicated, independent natural laboratories of
evolution and ecology.

Fifteen Years Of Lessons From The Seascape Approach: A Framework For Improving Ocean Management At Scale 1623274618
Author(s): Shannon E. Murphy, Ginny Farmer, Laure Katz, Mark V. Erdmann and more
Tags:
Description: Seascapes are large, multiple-use marine areas, defined scientifically and strategically, in which government authorities, private organizations, and other stakeholders cooperate to conserve the diversity and abundance of marine life and promote human well-being. This approach has been applied by global nonprofit partnerships in five seascapes across eight countries and has drawn on the practical experience of more than 250 partners over 15 years. These experiences have helped define the Seascape approach, consisting of nine essential elements, for achieving effective ocean governance and management from local to regional levels. Lessons learned relate to using integrated planning frameworks, community-led and locally owned initiatives, and a network of partners and a “backbone” organization for effective Seascape planning and design; promoting diversification in funding sources, private sector engagement, and the transition of nonprofit roles to ensure durability of a Seascape; and ensuring Seascape outcomes are measured through robust monitoring and evaluation frameworks and communicated effectively. Seascapes are unique in their ability to create a pathway toward sustainable development. To ensure support and amplification of the approach, they must align with diversified funding opportunities and global priorities outlined in international United Nations conventions focused on sustainable development and ocean health.

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.

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.

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.

Excerpt On Sea Surface Temperature Monitoring From Final BHS EBM II Report 1394662301
Author(s): Mark Erdmann; Gandi Purba
Tags: climate change, MPA, BHS, sea surface temperature, 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.

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.
