Fish Stories

8232The keynotes from climate scientist Ralph Keeling and biologist Stephen Mayfield on the impacts of climate change on the ocean were terrific – but it was Rob Ruiz, the executive chef of The Land and Water Company who really stood out.

He talks here about how he traveled the world to observe local, sustainable sourcing and put what he learned to work in his Carlsbad restaurant. He credits the scientists at Scripps Institution of Oceanography for helping him select sustainable seafood for his menu and is proud to be recognized as a world leader for his commitment to ocean conservation. Clearly, he’s doing more than just talking the talk.

Watch Ruiz and the others as they engage with high school students in Blue Oceans, Sustainable Seafood, Humans and the Sea, the latest installment of STEAM Leadership Series.

Unleash the Dragons! (Seadragons, that is.)

8232It’s not often that a new species is discovered almost 100 years after it was first collected and described. But we’re in a new age of taxonomy powered by new genetic and anatomical imaging tools.

While researching the two known species of seadragons as part of an effort to understand and protect the exotic and delicate fish, scientists at Scripps Institution of Oceanography at UC San Diego made a startling discovery: a third species of seadragon.

Using DNA and anatomical research tools, Scripps graduate student Josefin Stiller and marine biologists Nerida Wilson of the Western Australia Museum (WAM) and Greg Rouse of Scripps Oceanography found evidence for the new species while analyzing tissue samples supplied by WAM. The researchers then requested the full specimen as well as photographs taken just after it was retrieved from the wild in 2007. They were further surprised by the appearance of the newly identified animal. The color was a bright shade of red and vastly different from the orange tint in Leafy Seadragons and the yellow and purple hues of Common Seadragons.

Stiller, Wilson, and Rouse gave their new discovery the scientific name Phyllopteryx dewysea, also referred to as the “Ruby Seadragon.”

Watch Unleash the Dragons! as Stiller shares the secrets of this newly described specie of seadragon and how it was discovered.

In the Spirit of Sally Ride: Margaret Leinen

8232Margaret Leinen, the warm and inspiring director of the Scripps Institution of Oceanography, is the first “star” in The Constellation, a new interview series presented by Sally Ride Science@ UC San Diego featuring women enjoying successful and satisfying lives in science.

Leinen describes how her early interest in rocks led to a career in protecting the seas. Among the highlights – leading the UC delegation to the international climate talks in Paris. She and her colleagues spread the word that climate change is leaving the oceans “hot, sour and breathless.”

Understand Climate Change – and What You Can Do About It

Learn more about climate change with new programs that examine its impact from a variety of perspectives. Discover how humans and climate interact and affect one another, learn what you can do to reduce greenhouse emissions, and get a behind-the-scenes look at the Pope’s call to protect the environment.

8232Climate Change, Consumerism and the Pope with Daniel Kammen and Jennifer Granholm

After being summoned to the Vatican to advise on climate change, Dan Kammen of UC Berkeley shares an insider’s view on what inspired Pope Francis to issue such a passionate plea to protect the earth in Laudato Si, his 2015 encyclical on the environment. As a practicing Catholic, former Michigan Governor Jennifer Granholm praises the Pope for presenting “human ecology” as a moral issue in this lively exchange with Kammen and Henry E. Brady, dean of the Goldman School of Public Policy at UC Berkeley.

8232What Are You Going to Do About It? The Effect of Uncertainty on Climate Change Policy

Taking action to reduce greenhouse gas emissions imposes costs now in order to avoid potentially very large costs from more severe climate change in the future. Steve Polasky, Professor of Ecological/Environmental Economics University of Minnesota, reviews major sources of uncertainty and how that alters the choice of optimal climate change policy. He discusses current debates on how best to frame climate change policy, and whether it should be framed as setting limits on greenhouse gas concentrations to avoid potentially catastrophic damages or as an application of benefit-cost analysis.

8232CARTA: Human-Climate Interactions and Evolution: Past and Future

According to earth scientists, paleontologists, and scholars in other fields, the planet has entered a new geological phase – the Anthropocene, the age of humans. How did this transition of our species from an apelike ancestor in Africa to the current planetary force occur? What are the prospects for the future of world climate, ecosystems, and our species? This symposium presents varied perspectives on these critical questions from earth scientists, ecologists, and paleoanthropologists.

The Amazing Diversity of Fishes!

8232The aquatic world presents the widest diversity of habitats, so it’s no surprise that fishes have come to present the widest diversity of vertebrate species.

From the darkest depths to tropical shores, there are more than 33,000 species of living fishes, accounting for more than half of the extant vertebrate diversity on Earth.

For years, Curator of Scripps Institution of Oceanography’s Marine Vertebrate collection, Phil Hastings, has been immersed in the systematics and phylogeny of fishes, their marine biogeography, and the ecology and behavioral evolution of fishes, and takes you on a tour of what makes this most diverse array of animals.
