Brown bears have opened the fishing and fattening season at Brooks Falls, Katmai National Park & Reserve, Alaska. It is an all you can eat season depending on fishing skills, the salmon and bear behavior.

As you know there are several cameras, one underwater to view the fish and an occasional paddling bear, a chance to observe catching and eating behavior, talks by biologists at the park (see right of screen) and weather conditions. All of this is in preparation for winter and for us, the now famous Fat Bear Week at season's end. You will note by reading the comments that there are some very dedicated watchers.

 

Otis, Bear 480, is legendary and this would be very early for an appearance. This page tells you about him and has a chart of his first appearances. Otis is old and there is always concern whether he made it through the winter. He has had to adapt to his age, giving up favorite fishing spots to others as well as changing his fishing techniques.

This page about the Brooks Falls Bear Cam is very useful and includes FAQS.

It was terrific to see an article on one of the smaller fishes of Minnesota, the endangered Topeka Shiner, on the front page of the news, poking above the fold in the June 17, 2024 StarTribune. For more about the fish see the Minnesota Department of Natural Resources Rare Species Guide. I draw attention to it at the top because the photograph shows just what a lovely fish it is. 

StarTribune environmental reporter Greg Stanley takes us on a field trip with biologists.

 

The essay is behind a subscription paywall. However, it may be read here. It includes one photograph. Here is a story from the Wildlife Management Institute on a similar project in Iowa.

I was struck by the immediacy of this effort. 

Thanks to Greg Stanley for his reporting of a story important to Minnesota citizens, to the Nature Conservancy for their part in the project, to the citizens of Minnesota for providing legislative support for the Minnesota Outdoor Heritage Fund and to the Star Tribune for publishing it and placing it on page one!

Astronomy Picture of the Day (APOD) has an image of a star which turns out to be a double star, seen only with telescopic aid.  It includes the visible spectrum of both stars which shows how different the two stars are.

The image is lovely and the explanation adds to the pleasure of seeing it as well as in not misunderstanding what you are seeing.

For stargazers, planet watchers, the constellation savvy, the scientific term "asterism" is well known. I'd never heard of it --not included in the explanation which gave me an idea of what a common term it is --  and Wiki explains the term.  The explanation also includes a comment on how astronomers/astrophysicists reason.

Lava Study: Lab and Field

Ed Hessler

This video (11m 45s) from #ScienceInsider is about how scientists study lava. Of course they collect samples but how and where? There is more to the study of volcanology than doing field work. There is the laboratory, too and I very much like how the video bring field and lab work together.

The Syracuse University Lava Project is included and represents the laboratory side of the study-of-lava equation, science practices in action. An interesting aspect of the Lava Project is that it is a result of a collaboration between sculptor Bob Wysocki (SU Department of Art) and geologist Jeff Karson (SU Department of Earth Sciences). The page is well worth taking a look at.

Animals and Earth Quake Predictions

Ed Hessler

The second of two presentations by Sabine Hossenfelder on earthquake prediction, she discusses short-term forecasts, "from months to seconds. In this one she again calls attention to their human toll. "[E]arthquakes are the most fatal natural disasters. In the two decades from 1998 to 2017, they killed more than 700 thousand people." Then she asks,

"So what are seismologists doing to warn people of earthquakes? Can animals sense if an earthquake is coming? And what are earthquake lights? That’s what we will talk about today. ...  Short-term predictions don’t help with infrastructure investments, but they give people time to evacuate."

The non-seismic precursors may attract your attention because those involving animals are commonly reported. First, Hossenfelder includes a discussion of several short-term physical precursors "that are fairly well established though not all are well understood before she turns her attention to animals. 

She ends by talking about the "heavy burden" that comes with predictions, i.e., when they are wrong. She makes a suggestion that seem a worthy and important component of any prediction.

The video can be watched on YouTube but I like being able to read the text along with listening.

CBC's Bob McDonald ties the bow around the 48th season of Quirks & Quarks (June 21, 2024) with what has become an annual favorite: Listener's questions and expert answers. The answers are short, each is accompanied by a photograph, and there is a link to the expert.

I will not include the questions but they are related to the moon's orbit, animal sizes, gray hair, tectonic plates, fear, hydropower, effects of planting wild plants in cities on animal populations, matter, hibernation, and planetary effects on the sun.

6000 Years of Forest Landscapes and Sounds, United Kingdom Interactive

Environmental & Science Education, STEM, Biodiversity, Nature, Wildlife, Climate Change, Global Change

Ed Hessler

The story of the world's woodlands is one of overwhelming decline, " writes Sophie Yeo for Inkcap Journal in the introduction to Six Thousand Years of Forests, an amazing visual and aural interactive featuring the declines in United Kingdom (UK).

Yen's short introduction concludes with this observation. "The primeval forests have given way to an intensively farmed and settled landscape. Today, just 13% of the UK is covered by woodland, of which only 2.5% is more than 400 years old. If this was ever a woodland nation, it is not anymore."

By scrolling you can "see how land use has changed across the last eight millennia." "Anthromes" short for  Anthropogenic Biomes, or Human Biomes, are the globally significant ecological patterns created by sustained interactions between humans and human patterns created by sustained interactions between humans and ecosystems, iincluding urban, village, cropland, rangeland and seminatural anthromes." (see here).

Viewers comments include words and phrases such as "Fabulous,:"a creative re-telling," and"Amazing." Oh yes, these and more accolades. One comment critical of the work must have run, not walked through the forest depictions," with Yeo responding "the second paragraph makes that very point, with a link to the very study that you have included in your comment." 

The Inkcap Journal is longform journalism about nature and conservation in Britain. Members can receive a free weekly digest every Friday on nature news in Britain. Yeah, I know that all this information about the journal is in the masthead of today's feature but if, like me, you wanted to start hiking, it is easily missed.  I lumbered right by it the first time.

Comments on Anthony Fauci's "On Call"

Environmental & Science Education, STEM, Health, Medicine, Science & Society

Ed Hessler

In his forty year career as an infectious disease specialist, Dr.Anthony Fauci advised seven presidents on infectious diseases.  

 

In a forthcoming memoir, On Call: A Doctor’s Journey in Public Service, STAT's General Assignment Reporter, Jason Mast notes that "he strove to speak with complete candor and stay out of politics, while remaining strategic in pushing for policies he considered vital to public health."

Mast discusses his top takeaways from his reading of the 455 page book. They are:

-- Of course, he would do things differently on Covid-19 if given another shot.

-- The U.S. response to the pandemic succeeded on science, and failed on public health.

-- Local health officials tried to warn Fauci, who tried to warn the White House, that contact tracing was failing.

-- Fauci grew increasingly concerned about the politicization of science during the 2015-2016 Zika outbreak.

-- But Covid was unlike anything else.

-- An HIV vaccine may be far, far off, if it’s possible at all.

-- He advocated for efforts on TB, HIV, and malaria that didn’t see the light of day.

-- Fauci turned down an offer, in 1989, to become NIH chief.

-- He tried to squeeze greater and greater funding for HIV out of administrations with a deft hand.

Mast's essay, "Inside Anthony Fauci’s ‘On Call’: 9 health and science takeaways from the memoir of America’s most famous doctor", may be read here.

And here for your information is the Amazon entry. The book was released on June 18. It should quickly accumulate reader reviews.

I've seen two interviews with Dr. Fauci about the book. This one by CNN's Dr. Sanjay Gupta really stood out. It is 11m 28s long. Be patient, it begins with some introductory comments.

Viking Age Hunters and Blue Whales

Environmental & Science Education, Science & Society, Wildlife, Nature, Society, Culture, Nature of Science, History of Science

Ed Hessler

This is based on an essay in Hakai: Coastal Science and Societies in which writer Andrew Chapman discusses "new research (that) suggests that medieval Icelanders were scavenging and likely even hunting blue whales before industrial whaling technology."

Chapman begins by relating the story of a 17th century Icelandic fisherman who thrust his spear into a blue whale. The spear "would have been marked with the (fisherman's) emblem  and if all went well (the whale would have been mortally wounded and) "would wash  up dead on a nearby shore" where he would collect his bounty.

The whale didn't but ended up on the shores of Greenland some 1700 km (~1056 miles) to the west on a Greenland beach where it was eaten by a party, "staving off starvation." They found the marked spear tip but knew that the whale could not be delivered to the Icelandic fisherman.

Chapman tells us about the work of environmental historian Dr. Vicki Szabo, Western Carolina University who has been studying Norse texts for some three decades. Since 2015 she has been leading a multidisciplinary team of archaeologists, historians, folklorists, and geneticists to try to answer...whether medieval Icelanders (were) really hunting blue whales centuries before the invention of exploding harpoons and faster steam-powered ships? If so, how were they doing it, and how often?" Grant information, an abstract and publications produced as a result of the research is linked in Chapman's essay (multidisciplinary team).

This research is another dramatic example of the use of DNA analytic technologies. Oh the changes they have wrought in leading researchers to new knowledge, understanding and corroborating evidence for hypotheses, one way or the other. DNA it was found that over half of 124 whale bones analyzed were those of blue whales. Chapman notes that the results "staggered" Szabo.

The story becomes even more exciting with Szabo learning about a new site which is a whalebone paradise. Weather conditions at the site are miserable (powerful winds and rains) but each year the ocean is removing more and more whale bones to the deep. And the end of her her grant is projected to be mid-November, 2024.

Chapman includes many details of the use of whales for food by these Icelanders, the shift to modern whale hunting techniques, meat storage techniques, societal changes including complicated laws, and the variety of uses of whale bones.

Chapman ends with a story of the Icelandic fisherman who speared the whale at the beginning. He had a later experience that led him to quit spearing which is deeply moving. 

This is a wonderful story, beautifully illustrated with images of old texts, maps, and drawings as well as photographs.

Caltech celebrates the life of discovery led by Ed Stone, the David Morrisroe Professor of Physics and Project Scientist for Voyager missions.

 

This Caltech Press release includes a video (4m 25s) shot in 2017 in which Dr. Stone describes his career at Caltech and JPL, and the moment Voyager discovered active volcanoes on Jupiter's moon, Io.

You see scientists at work as they attempt to understand hot spots found on Io. It is a great story about a career in science and how scientists work interpreting data to find convincing evidence. Professsor Stone came to Caltech with a research agenda and it is fascinating to hear him weigh the invitation to join the NASA effort so early in his career.

PFAS. "per- and polyfluoroalkyl chemicals...are long-lasting-compounds that ...have been linked to cancer, liver damage, thyroid disease, and other ailments." Now that is a worrisome list and the issue is they show up in nearly everywhere, e.g., soil, ground water, drinking water sources, even rainfall." In other words, you can't hide from them. "By some estimates, this toxic family of chemical can be found in the blood of nearly every person on the planet.

Their uses include firefighting foams, waterproof clothes and nonstick cookware.

They are commonly called "forever chemicals," with reason.

CBS Sunday Morning correspondent Lee Cowan provides a tour of how they became so ubiquitous, "and talks with families, farmers, and health advocates fighting for clean, save water."

The video is 11m 21s long.

"Robbery" In Nature

Ed Hessler

I refer you to another post in WEIT's  Readers' Wildlife Photos. It is about "nectar robbers" and is by Athayde Tonhasca Junior. I'm always tempted to call him a photojournalist because of the approach he takes to his frequent posts. I don't want you to miss it. It is an informed and lavishly illustrated story whose purpose is to expand your understanding the natural world.

This entry is the second that begins with observations made by Christian Konrad Spengel. The first one I posted is titled "Deceptive Flowers."

Ahayde Tonhasca Junior closes with an observation  made by Sprengel who "labelled nectar robbing an 'outrage against a flower' and Darwin considered it 'a felony', but there's more to it than meets the eye." 

This is a perfect introduction to what his post is about. There is much more than meets the eye.

h/t WEIT (Emeritus Professor Jerry A. Coyne) and Thayde Tonasca Junior. Thanks once again.

A Remembrance: Astronaut William Anders Photographer of Earthrise

Ed Hessler

An iconic image that gave a boost to the nascent environmental movement is the center of this NASA Remembers biography (3m 28s) of the late William Anders, the astronaut who took it. 

What an image, what a career and what a life-changing event for Anders (see Earthrise, Wiki).

The mission "round the moon and back" was the last of the Apollo missions, number 8, crewed by William Anders, Frank Borman, and James Lovell. The facts about this mission may be found in this NASA summary.
