Cnidariology with Shayle Matsuda Ologies Podcast July 25, 2019
Cnidariology with Shayle Matsuda Ologies Podcast July 25, 2019 Oh heeey, it’s your karate teacher, who smells like your college sweetheart, and so you’re weird around them, Alie Ward, back with another episode of Ologies. This episode was recorded in beautiful Hawaii – ever heard of it? – a few weeks ago. You’re about to just get an earful of coral. But, before I recorded it, honestly, I knew neither jack nor shit about coral. Now, all I want to do is stare at videos of coral. Honestly, I used to just consider them to be the really plucky, kind of quirky settings of a snorkeling jaunt. Kind of like a splashy backdrop at a community theater play. Like, “Oh that’s nice, but what’s happening in front of them? What kind of fish do we have?” Au contraire! After this episode you’ll be like, “Move out of the way, fish! I’m staring at a polyp.” And yeah, it’s totally fine if you don’t know what a polyp is, we will get to that. But first, thank you to all the folks that support the show at Patreon.com/Ologies for as little as a dollar a month; you can submit questions. Also, thanks to everyone who buys and wears shirts, and hats, and such, from OlogiesMerch.com. We have some new denim Dad hats, if you need a new lid that says, “I like weird facts, good intentions, and bad puns.” It doesn’t literally say that. I’m just saying, people will go, “Oh, that’s what you’re into.” Although that’s not a bad idea for a hat. -

Leong Climate Change Testimony
WRITTEN TESTIMONY OF JO-ANN C. LEONG, Ph.D. HAWAII INSTITUTE OF MARINE BIOLOGY SSCHOOL OF OCEAN & EARTH SCIENCE & TECHNOLOGY UNIVERSITY OF HAWAII AT MANOA HEARING ON CLIMATE CHANGE IMPACTS AND RESPONSES IN ISLAND COMMUNITIES BEFORE THE COMMITTEE ON COMMERCE, SCIENCE AND TRANSPORTATION UNITED STATES SENATE March 19, 2008 Introduction Good morning Senator Inouye and members of the Committee. Thank you for the opportunity to speak before you on the impacts of climate change on Hawai‘i’s myriad ocean species at the level of coral reef resilience and resistance to invasive species. My name is Jo- Ann Leong and I serve as Director of the Hawai‘i Institute of Marine Biology. I represent a group of scientists whose major research effort includes the study of coral reef ecosystems and the biological connectivity between the islands and atolls of the Hawaiian Archipelago. We have a memorandum of agreement with the NOAA Pacific Regional Sanctuary office to provide research for the new Papahanaumokuakea Marine National Monument. Current models for sea surface temperature (SST) and seawater CO2 saturation in the coming decades suggest that the Hawaiian Archipelago will experience rises in sea levels, increased episodes of coral bleaching, and decreased aragonite saturation in its ocean waters (Guinotte, Buddemeier, Kleypas 2003; IPCC, 2007 working group I report; E. Shea, Preparing for a Changing Climate, 2001). Higher sea surface temperatures produced severe bleaching events in the main Hawaiian Islands in 1996 and in the Northwestern Hawaiian Islands (NWHI) in 2002 and 2004. Climate experts are virtually certain that more episodes of coral bleaching are in store for Hawai‘i. -
A Study Guide by Dave Crewe
CAN WE SAVE THE REEF? http://www.metromagazine.com.au http://theeducationshop.com.au A STUDY GUIDE BY © ATOM 2018. ISBN: 978-1-76061-146-0 DAVE CREWE Can We Save the Reef? is the epic story of Australian and international scientists who are racing to understand our greatest natural wonder, and employing bold new science in an attempt to save it. Professor Emma Johnston is a passionate diver, leading marine biologist and board member of the Great Barrier Reef Marine Park Authority. It’s part of her mission as a scientist, and an Australian, to protect our Reef. Both hard-hitting and hopeful, Professor Johnston shows us how no two reefs are the same and how other reef systems, like those in Hawaii, are proving to be valuable testing grounds for what can be done at home to help our Reef survive. Working with Australian scientist Dr Madeleine van Oppen, Dr Ruth Gates in Hawaii is identifying INTRODUCTION and testing coral species with the greatest resilience – part of their joint work to breed Can We Save the Reef? is an Australian coral under warmer, more acidic, future-ocean documentary written and directed by Adam conditions.

Immerse Learning Activity 051420
The Hydrous Presents: IMMERSE PLUS A Learning Activity to experience, explore and engage the Ocean Immerse is a 9 minute virtual dive on the coral reefs of Palau with marine biologist Dr. Erika Woolsey as your guide. Swim with manta rays, sea turtles, and sharks while you explore beautiful and threatened coral ecosystems. Narrated by marine scientists and young ocean advocates, this experience seeks to inspire ocean connection and understanding. This Immerse Learning Activity is designed to supplement the Immerse 360/VR experience.. We created it for educators, parents, and friends to share the ocean with others and think deeply about marine environments. These materials are adapted from Coral Reefs: A Hydrous Learning Expedition, an educational prototype created in 2019 with funding from the National Geographic Society (award CP-132E-17). The Hydrous is currently developing a curriculum product building on these materials.

Reasons to Sequence the Genome of the Dinoflagellate Symbiodinium Thomas G
Symbiodinum_WPl+Appendix_v2.doc 1 Reasons to sequence the genome of the dinoflagellate Symbiodinium Thomas G. Doak, Princeton, USA. <[email protected]> Robert B. Moore, University of Sydney, AU. <[email protected]> Charles Delwiche University of Maryland at College Park, USA <[email protected]> Ove Hoegh-Guldberg, University of Queensland, AU. <[email protected]> Mary Alice Coffroth, State University of New York at Buffalo, USA. <[email protected]> Abstract Dinoflagellates are ubiquitous marine and freshwater protists. As free-living photosynthetic plankton, they account for much of the primary productivity of oceans and lakes. As photosynthetic symbionts, they provide essential nutrients to all reef-building corals and numerous other marine invertebrates, supporting coral reefs, the most diverse marine ecosystem, a rich food source, and a potential source of future pharmaceuticals. When the dinoflagellate symbionts are expelled from their coral hosts during mass coral bleaching events, coral reefs and the surrounding ecosystems rapidly decline and die. Population explosions of dinoflagellates are the cause of red tides, extensive fish kills, and paralytic shellfish poisoning. As parasites and predators, they threaten numerous fisheries, but are also an important check on the very dinoflagellates that cause red tides. As bioluminescent organisms, they are a spectacular feature of nighttime oceans and a model for the study of luminescence chemistry. Dinoflagellates are alveolates and a sister group to the apicomplexans–important human and animal pathogens. The apicomplexans are obligate intracellular parasites, e.g. Plasmodium spp. the agents of malaria. Describing the genome of a dinoflagellate that is an intracellular symbiont will aid us in understanding the capacities, weaknesses and evolution of the apicomplexans, and will inform the apicomplexan genomes in a way directly relevant to the development of antimalarial and anti- apicomplexan drugs. -
A Role for Assisted Evolution in Designing Native Plant Materials for Domesticated Landscapes TA Jones* and TA Monaco
CONCEPTS AND QUESTIONS A role for assisted evolution in designing native plant materials for domesticated landscapes TA Jones* and TA Monaco Developers of native plant propagation materials for wildland restoration may emphasize naturally occur- ring genetic patterns or, in contrast, the material’s empirical performance in comparative field trials. We contend that both approaches have value and need not be mutually exclusive. Anthropogenic influences have pushed many ecosystems across ecological thresholds, to less desirable states, so that actively manag- ing for “domesticated nature” – nature as modified, either intentionally or inadvertently, by humans – is more realistic and more likely to succeed than recreating the original ecosystem. Furthermore, when domes- ticated nature is the most reasonable objective, empirical performance, together with geographical origin, are plausible criteria for choosing restoration plant material. For altered ecosystems, we suggest that evolu- tion should be assisted by the inclusion of plants that (1) reflect general historical evolutionary patterns, (2) are particularly suited to the modified environment, (3) are able to adapt to contemporary selection pres- sures, and (4) contribute to the restoration of ecosystem structure and function.
