RAJA AMPAT MARINE PARK, INDONESIA: The Heart of the Coral Triangle — Conservation Atlas 12/26/18, 10:08 AM DECEMBER 12, 2018 RAJA AMPAT MARINE PARK, INDONESIA: The Heart of the Coral Triangle Text: Andreea Lotak; Photographs: Justin & Andreea Lotak • 10 min read The stunning beauty of the Fam Islands as seen from above, Raja Ampat There aren’t many places left on Earth with ecosystems as healthy as those in the Raja Ampat Marine Park. There are over 1,700 species of fish here — with a few dozens of them found nowhere else — swimming among what represents 76% of the world’s coral diversity. The park’s crystal waters protect an area stretching across 35,000 sq km (13,500 sq mi), where large gatherings of manta rays, sharks, whales, mollusks, fish and other aquatic organisms are attracted by the rich nutrients brought by strong oceanic currents. Among all this natural beauty there are roughly 50,000 residents living in villages, settlements and the small town of Waisai, surrounded by limestone cliffs shooting from the turquoise waters and by dense forests where the loud birdsong creates a perfect musical background for a tropical paradise. https://www.conservationatlas.org/blog/raja-ampat-marine-park-indonesia-the-heart-of-the-coral-triangle2018 Page 1 of 15 RAJA AMPAT MARINE PARK, INDONESIA: The Heart of the Coral Triangle — Conservation Atlas 12/26/18, 10:08 AM The Coral Triangle is located at the confluence of the Western Pacific and Indian Oceans, spread across the waters and coastlines of six countries: Indonesia, the Philippines, Papua New Guinea, Malaysia, Solomon Islands and Timor Leste. -

Reference Transcriptome for the High- Antarctic Cryopelagic Notothenioid Fish Pagothenia Borchgrevinki Kevin T Bilyk1,2* and C-H Christina Cheng1
Bilyk and Cheng BMC Genomics 2013, 14:634 http://www.biomedcentral.com/1471-2164/14/634 RESEARCH ARTICLE Open Access Model of gene expression in extreme cold - reference transcriptome for the high- Antarctic cryopelagic notothenioid fish Pagothenia borchgrevinki Kevin T Bilyk1,2* and C-H Christina Cheng1 Abstract Background: Among the cold-adapted Antarctic notothenioid fishes, the high-latitude bald notothen Pagothenia borchgrevinki is particularly notable as the sole cryopelagic species, exploiting the coldest and iciest waters of the Southern Ocean. Because P. borchgrevinki is a frequent model for investigating notothenioid cold-adaptation and specialization, it is imperative that “omic” tools be developed for this species. In the absence of a sequenced genome, a well annotated reference transcriptome of the bald notothen will serve as a model of gene expression in the coldest and harshest of all polar marine environments, useful for future comparative studies of cold adaptation and thermal responses in polar teleosts and ectotherms. Results: We sequenced and annotated a reference transcriptome for P. borchgrevinki, with added attention to capturing the transcriptional responses to acute and chronic heat exposures. We sequenced by Roche 454 a normalized cDNA library constructed from pooled mRNA encompassing multiple tissues taken from environmental, warm acclimating, and acute heat stressed specimens. The resulting reads were assembled into 42,620 contigs, 17,951 of which could be annotated. We utilized this annotated portion of the reference transcriptome to map short Illumina reads sequenced from the gill and liver of environmental specimens, and also compared the gene expression profiles of these two tissue transcriptomes with those from the temperate model fish Danio rerio. -
Induction of Heat Shock Proteins in Cold- Adapted and Cold
CORE Metadata, citation and similar papers at core.ac.uk Provided by ScholarWorks@UA INDUCTION OF HEAT SHOCK PROTEINS IN COLD- ADAPTED AND COLD- ACCLIMATED FISHES By Laura Elizabeth Teigen Dr. Kristin O'Brien Advisory Committee Chair Dr. Diane Wagner Chair, Department of Biology and Wildlife APPROVED: ;t.-/ INDUCTION OF HEAT SHOCK PROTEINS IN COLD- ADAPTED AND COLD- ACCLIMATED FISHES A THESIS Presented to the Faculty of the University of Alaska Fairbanks in Partial Fulfillment of the Requirements for the Degree of MASTER OF SCIENCE By Laura Elizabeth Teigen, B.A. Fairbanks, Alaska May 2014 v Abstract I examined the effects of oxidative stress and changes in temperature on heat shock protein (Hsp) levels in cold-adapted and cold-acclimated fishes. Adaptation of Antarctic notothenioids to cold temperature is correlated with high levels of Hsps, thought to minimize cold-induced protein denaturation. Hsp70 levels were measured in red- and white-blooded Antarctic notothenioid fishes exposed to their critical thermal maximum (CTMax), 4C warm acclimated, and notothenioids from different latitudes. I determined the effect of cold acclimation on Hsp levels and the role of sirtuins in regulating Hsp expression and changes in metabolism in threespine stickleback, Gasterosteus aculeatus, cold-acclimated to 8C. Levels of Hsps do not increase in Antarctic notothenioids exposed to their CTMax, and warm acclimation reduced levels of Hsp70. Hsp70 levels were higher in Antarctic notothenioids compared to a temperate notothenioid and higher in white-blooded notothenioids compared to red-blooded notothenioids, despite higher oxidative stress levels in red-blooded fish, suggesting Hsp70 does not mitigate oxidative stress. -

Moran, Dean College of Fisheries and Ocean Sciences Michael Castellini, Dean of the Graduate School Abstract The role of dietary protein in pinniped (seal and sea lion) nutrition is poorly understood. Although these marine mammals derive the majority of their daily energetic needs from lipid, lipids cannot supply essential amino acids which have to come from protein fractions of the diet. Protein regulation is vital for cellular maintenance, molt, fasting metabolism, exercise and development. Proteins are composed of linked amino acids (AA), and net protein turnover is the balance between protein synthesis from component AA, and degradation back to AA. Protein regulation is influenced by dietary intake and quality, as well as physiological and metabolic requirements. In this work, pinniped diet quality was assessed through comparisons of amino acid profiles between maternal milk, blood serum, and seasonal prey of wild juvenile Steller sea lions (Eumetopias jubatus) in Southcentral Alaska. -
The Importance of Antarctic Toothfish As Prey of Weddell Seals in the Ross
Antarctic Science 21(4), 317–327 (2009) & Antarctic Science Ltd 2009 doi:10.1017/S0954102009001953 Review The importance of Antarctic toothfish as prey of Weddell seals in the Ross Sea DAVID G. AINLEY1* and DONALD B. SINIFF2 1HT Harvey & Associates, Los Gatos, CA 95032, USA 2Department of Ecology, Evolution and Behavioral Biology, University of Minnesota, St Paul, MN 55108, USA *[email protected] Abstract: Uncertainty exists over the importance of Antarctic toothfish (Dissostichus mawsoni) as prey of top predators in the Ross Sea. In this paper we assess relative weight given to direct, observational evidence of prey taken, as opposed to indirect evidence from scat and biochemical analysis, and conclude that toothfish are important to Weddell seals (Leptonychotes weddellii). The seals eat only the flesh of large toothfish and therefore they are not detected in scat or stomach samples; biochemical samples have been taken from seal sub-populations where toothfish seldom occur. Using direct observations of non-breeding seals away from breeding haulouts in McMurdo Sound, 0.8–1.3 toothfish were taken per day. Based on these and other data, the non-breeding portion of the McMurdo Sound seal population, during spring and summer, consume about 52 tonnes of toothfish. Too many unknowns exist to estimate the non-trivial amount consumed by breeders. We discuss why reduced toothfish availability to Weddell seals, for energetic reasons, cannot be compensated by a switch to silverfish (Pleuragramma antarcticum) or squid. The Ross Sea toothfish fishery should be reduced including greater spatial management, with monitoring of Weddell seal populations by CCAMLR. Otherwise, probable cascades will lead to dramatic changes in the populations of charismatic megafauna. -
