“Extreme remedies are very appropriate for extreme diseases”*…

The Toad Mountain harlequin frog is endangered and at risk from the Bd fungus

 

A century ago, a strain of pandemic flu killed up to 100 million people—5 percent of the world’s population. In 2013, a new mystery illness swept the western coast of North America, causing starfish to disintegrate. In 2015, a big-nosed Asian antelope known as the saiga lost two-thirds of its population—some 200,000 individuals—to what now looks to be a bacterial infection. But none of these devastating infections comes close to the destructive power of Bd—a singularly apocalyptic fungus that’s unrivaled in its ability not only to kill animals, but to delete entire species from existence.

Bd—Batrachochytrium dendrobatidis in full—kills frogs and other amphibians by eating away at their skin and triggering fatal heart attacks. It’s often said that the fungus has caused the decline or extinction of 200 amphibian species, but that figure is almost two decades out-of-date. New figures, compiled by a team led by Ben Scheele from the Australian National University, are much worse.

Scheele’s team estimates that the fungus has caused the decline of 501 amphibian species—about 6.5 percent of the known total. Of these, 90 have been wiped out entirely. Another 124 have fallen by more than 90 percent, and their odds of recovery are slim. Never in recorded history has a single disease burned down so much of the tree of life. “It rewrote our understanding of what disease could do to wildlife,” Scheele says…

The story of an unprecedented pathogen: “The Worst Disease Ever Recorded.” (Lest one rest too easily because this threat seems to target not humans but animals at some distance on the tree of life, see here.)

As we do our best to stave off extinctions, we might recall that on this date in 1981, Nature set the world’s record for “Longest Scientific Name” when it published the systematic name for the deoxyribonucleic acid (DNA) of the human mitochondria; it contains 16,569 nucleotide residues and is thus about 207,000 letters long.

The Treeographer [is] a collection of the true histories of significant or symbolic trees from around the world. The stories cover a wide variety of topics, including culture, history, science, religion, and more… All of the stories to date are organized geographically in the Archive. If you aren’t sure where to start, try Ogawa’s Sacred Cedar – A 780 Million Yen Rescue Mission

As we take the shade, we might spare a thought for Gerald “Gerry” Malcolm Durrell; he died on this date in 1995.  A British naturalist, zookeeper, conservationist, author, and television presenter, most of his work was rooted in his life as an animal collector and enthusiast… though he is probably most widely known for his autobiographical book My Family and Other Animals and its successors, Birds, Beasts, and Relatives and The Garden of the Gods... which have been made into television and radio mini-series many times, most recently as ITV’s/PBS’s The Durrells.

“A fox knows many things, but a hedgehog one important thing”*…

 

Hedgehogs rolling on the ground to collect grapes for their young, as illustrated in the Rochester Bestiary (England, c. 1230): London, British Library, Royal MS 12 F XIII, f. 45r. Hedgehogs were said to creep into vineyards when the grapes were ripe, to climb the vines and shake the fruit down to the ground. Then, rather than eating this bounty on the spot, they would turn onto their backs and roll around, impaling the grapes with their sharp quills. They could then trundle off back to their burrows, carrying the grapes on their spines, as a meal for their young. The bestiary writers allegorized this as a warning of the clever stratagems of the devil in stealing man’s spiritual fruits.

Longstanding readers of our Medieval Manuscripts Blog may know that we have a penchant for hedgehogs. In 2012, we published a post entitled The Distinguished Pedigree of Mrs Tiggy-Winkle,based on the accounts of their behaviour in medieval bestiaries. In 2014, we brought you a hedgehog beauty contest, no less, featuring images of five of our favourites. And most recently we focused on the heraldic hedgehog in the 13th-century Dering Roll.

We’ve now discovered this fantastic animation, based on the drawings of hedgehogs in one of the British Library’s medieval bestiaries (Royal MS 12 F XIII, f. 45r). De Herinacio: On the Hedgehog was made by the amazing Obrazki nunu and Discarding Images. We hope that you love it as much as we do! Maybe it will inspire more people to explore and reinvent our wonderful collections…

As we roll in it, we might recall that it was on this date in 1869 that the first issue of the journal Nature was published.  Taking it’s title from a line of Wordsworth’s (“To the solid ground of nature trusts the Mind that builds for aye”), its aim was to “provide cultivated readers with an accessible forum for reading about advances in scientific knowledge.”  It remains a weekly, international, interdisciplinary journal of science, one of the few remaining tat publish across a wide array of fields.  It is consistently ranked the world’s most cited scientific journal and is ascribed an impact factor of approximately 38.1, making it one of the world’s top academic journals.

“All photographs are memento mori”*…

As we check those photos in our wallets, we might spare a thought for Eliot Porter; he died on this date in 1990.  An American photographer, he is best known for his color photographs of nature. With encouragement from Alfred Stieglitz and Ansel Adams, Porter turned an adolescent hobby into his profession.

Porter was the first established artist-photographer to commit to exploring the beauty and diversity of the natural world in color photographs.  Over much of his career, black-and-white photography set the artistic standard, and he had to fight his colleagues’ prejudices against the medium. But in 1962 the Sierra Club published “In Wildness Is the Preservation of the World.”  That immensely popular book, combining his evocative color photographs of New England woods with excerpts from the writings of Henry David Thoreau, revolutionized photographic book publishing, and legitimized color.  Its success set Porter on a lifelong path of creating similar photographic portraits of a wide variety of ecologically significant locations the world over.

“Teaching is not a lost art, but the regard for it is a lost tradition”*…

 

 

school

One quibbles with Jacques Barzun, the author of this post’s title quote, at one’s peril.  Still, as Lapham’s Quarterly points out, disrespect, even disdain for formal education has a long history.  In this season of school’s end, LQ reaches back to the 17th Century for an example: an excerpt from Nicholas Breton’s The Court and Country, in which the then-popular author argues that on-the-job training, in the fields where husbands know their wives and farmers know their cattle, is all the learning anyone needs:

Now for learning, what your neede is thereof I know not, but with us, this is all we goe to schoole for: to read common Prayers at Church and set downe common prices at Markets; write a Letter and make a Bond; set downe the day of our Births, our Marriage Day, and make our Wills when we are sicke for the disposing of our goods when we are dead. These are the chiefe matters that wemeddle with, and we find enough to trouble our heads withal. For if the fathers knowe their owne children, wives their owne husbands from other men, maydens keep their by-your-leaves from subtle batchelors, Farmers know their cattle by the heads, and Sheepheards know their sheepe by the brand, what more learning have we need of but that experience will teach us without booke? We can learne to plough and harrow, sow and reape, plant and prune, thrash and fanne, winnow and grinde, brue and bake, and all without booke; and these are our chiefe businesses in the Country, except we be Jury men to hang a theefe, or speake truth in a man’s right, which conscience & experience will teach us with a little learning. Then what should we study for, except it were to talke with the man in the Moone about the course of the Starres?

* Jacques Barzun

As we celebrate the onset of summer, we might send back-to-nature birthday greetings to Ralph Waldo Emerson; he was born on this date in 1803.  The essayist (“Nature,” “Self-Reliance,” et al.), lecturer, and poet who led the Transcendentalist movement of the mid-19th century, he was one of the linchpins of the American romantic movement, and friend and mentor to Henry David Thoreau.
