Conservationists have been sounding the alarm over invasive species for years, warning of the damage they can cause to habitats and native animals. But in Florida, an invasive snail might be helping an endangered bird species come back from the brink, researchers say.
The population of North American snail kites — birds that use curved beaks and long claws to dine on small apple snails in the Florida Everglades — had been dwindling for years, from 3,500 in 2000 to just 700 in 2007. Things began to look particularly bleak in 2004, when a portion of the Everglades was invaded by a species of larger snail that the birds had historically struggled to eat. Ornithologists assumed the shift would hasten the snail kite’s decline. Continue reading
Thanks to the Trilobites feature on the New York Times website for this story of collaborative friendliness between species:
Chances are that’s a shy elk looking back at a bold magpie, in the photograph above.
They get along, so to speak, because the elk needs grooming and the magpie is looking for dinner. But they may have never entered into this partnership if it weren’t for their particular personalities, suggests a study published Wednesday in Biology Letters.
Let’s start with the elk. In Canada’s western province of Alberta, they’ve been acting strange. Some have quit migrating, opting to hang around towns with humans who protect them from predators like wolves. Others still migrate. Continue reading
Apart from Romantic poets and their wannabes, who would wish for elegance at the expense of longevity? Thanks to M. R. O’Connor for this inelegantly titled post:
Greenland sharks are among nature’s least elegant inventions. Lumpish, with stunted pectoral fins that they use for ponderously slow swimming in cold and dark Arctic waters, they have blunt snouts and gaping mouths that give them an unfortunate, dull-witted appearance. Continue reading
Yesterday’s topic touched on a taboo of sorts, but in the interest of furthering our understanding of one of the most remarkable organisms on the planet; today, likewise, thanks to Steph Yin for her note on creatures sometimes considered creepy but whose environmental services are remarkably valuable:
I was raised by grandparents who spoke only Mandarin, so I did not speak English until I went to preschool in Philadelphia. There, guided by English-speaking teachers and surrounded by toddlers babbling in loose English, I adopted the new language quickly.
Young bats may not be so different. Continue reading
Supposedly solitary pumas actually hang out with their fellow big cats quite often, frequently coming together and hissing and snarling before settling down to share a delicious elk carcass.
That’s the startling discovery made by scientists who recently tracked 13 pumas — also called mountain lions or cougars — and set up cameras at kill sites. They recorded dozens of peaceful social interactions between these elusive felines. Continue reading
Thanks to Joanna Klein and the Science section of the New York Times:
A genetic analysis showed that a stick insect found on another island was the same species as one that had been wiped out by rats on Australia’s Lord Howe Island.
The tree lobster, one of the rarest insects on Earth, has lived a rather twisted life story.
Scientifically known as Dryococelus australis, this six-inch-long stick bug with a lobster-esque exoskeleton once occupied Lord Howe Island in the Tasman Sea, between Australia and New Zealand. Continue reading
It has been quite some time since we linked out to an Ed Yong story, and title notwithstanding this is as good as they come:
The ethereal allure of a cave full of glowworms masks a sinister purpose and a weird origin story.
At first, they look like stars. I see them as I gaze upward at the ceiling of a flooded, pitch-black cave—hundreds of blue pinpricks. As my eyes habituate to the darkness, more and more of them resolve, and I see that they are brighter and more densely packed than any starry field. And unlike the night sky, these lights don’t appear as a flat canvas, but as a textured one. Some are clearly closer to us than others and they move relative to each other, so the whole tableau seems to undulate gently as our boat sails beneath it. These lights are not astrological, but entomological. They are produced by insects called glowworms. Continue reading
There’s no age limit to the human fascination with dinosaurs, so it’s good news for science that interest translates to collaborative efforts when public funding for exploration and documentation run low.
Raptor Cam? Sounds enticing!
Millions of years ago, on a mud flat somewhere in Cretaceous Utah, a group of Utahraptors made a grave mistake: They tried to hunt near quicksand. The pack’s poor fortune has given modern paleontologists an opportunity to decode the giant raptor — its appearance, growth and behavior — but only if they can raise the money.
Enter “The Utahraptor Project,” started on GoFundMe last year with a $100,000 goal. It offers backers access to a field worker’s blog, a live “Raptor Cam” and digital models of the find put together through the process of photogrammetry. While it is far from reaching its goal, the team is optimistic.
“Once we get this up and running, with all the cameras and gizmos to record the action on a micro and macro level,” said Scott Madsen, a fossil preparator, “I think we can give the public a good show for their money. Continue reading
Crist’s post about this fascinating National Geographic article last week touched on its excellent graphics but barely began to scratch the surface of the amazing technology that would certainly have left the readers of the early issues of the magazine speechless.
In addition to the world-class photography, the interactive 3-D graphic of the frieze above uses SketchFab technology to allow viewers to not only zoom in and out, but to turn the object around in all directions, as if handling it in person. Do take the time to play with it! Continue reading
We have mentioned Meg more than once since we met her a few years ago, because our interests are aligned. Thanks to this public radio station for reminding me that Meg is due for a visit to Belize (I say wishfully) for a 20-years later discovery trip, and we will be happy to see her at Chan Chich Lodge when the time comes:
For over 30 years, Dr. Meg Lowman –Canopy Meg, has designed hot-air balloons and walkways for treetop exploration to solve mysteries in the world’s forests, especially insect pests and ecosystem health. Meg is affectionately called the mother Continue reading
Discoveries in the lands once populated by the Maya continue apace. As Chan Chich Lodge completes three decades of archeological exploration, the wonders of three millennia are uncovered. The stories that capture my interest the most, related to the Maya, are about the man-nature relationship.
Erik Vance published this story last year, and when I read it then I remember thinking that it was the best article I had ever read in National Geographic. Partly, the graphics are better, if that is possible, than the typically excellent quality the magazine is known for. Also, the topic is more topical for me now. Chan Chich Lodge is situated exactly where the o in Holmul is on the map to the left. The lodge’s Maya foundations are situated at the periphery of where the snake kings once ruled.
And we now have an ethnobotanical initiative linking Maya foodways to our surrounding nature conservation. That initiative is linked to the lodge’s food program, with some high expectations related to our abundant forests. But mainly, with regard to this article, the writing illuminating the topic is excellent:
…Two warring city-states were locked in perennial conflict, grappling for supremacy. For a brief period one of those city-states prevailed and became the closest thing to an empire in Maya history. It was ruled by the Snake kings of the Kaanul dynasty, which until just a few decades ago no one even knew existed. Thanks to sites around this city-state, including Holmul, archaeologists are now piecing together the story of the Snake kings…
I am sure I remember seeing these in my childhood collection of books with pictures of prehistoric creatures. Like many boys, the saber-tooth tiger was a favorite, which may explain my preoccupation with the big cats at Chan Chich Lodge. When you favor cats, you get to know their diet, so creatures like these in the image above were also among those I was fascinated by, which would explain why the tapir I have seen in the forests surrounding Chan Chich are among my lifetime favorite wild animal sightings. Thanks to Steph Yin for this story:
It looked like many different animals and, at the same time, like no other animal at all.
From afar, you might think it was a large, humpless camel. Tall, stout legs ending in rhino feet carried a body weight potentially equal to that of a small car. Its neck stretched like a giraffe’s before giving way to a face resembling a saiga antelope’s. From this face extended a fleshy protuberance, similar to a mini elephant trunk or a tapir’s proboscis.

Todd Rundgren, a musical talent better known to an earlier generation, had an oddball hit song about banging on drums. It came to mind immediately when reading this oddball story about cockatoos. If you do not already know the song, you might want to find it to accompany your reading of this story:
Palm cockatoos from northern Australia modify sticks and pods and use them to drum regular rhythms, according to new research published in Science Advances on Wednesday. In most cases, males drop beats in the presence of females, suggesting they perform the skill to show off to mates. The birds even have their own signature cadences, not unlike human musicians.

When Crist wrote about the Chan Chich Archaeological Project in April it was in anticipation of the group’s arrival. Now that we’re several weeks in I’ve had the opportunity to assist them first hand, in part as a “guinea pig” for guest involvement as citizen science participants. Fellow contributor Phil Karp (a veteran of many citizen science programs) was enthusiastically up for the experience as well.
The team of archaeologists and field school students, led by Texas Tech University associate professor Dr. Brett Houk, is studying the ancient Maya at Chan Chich and surrounding sites. Several weeks into their dig they’ve made significant progress, and they gamely accepted the challenge of taking novices into their ranks.
We began at the beginning, well known to be the very best place to start, with a new “lot” located next to a well-established excavated area. Continue reading
Thanks to National Public Radio (USA) and Kat Lonsdorf for a brief look into the deep work of Tim O’Hara:
Far below the surface of the ocean, off the coast of eastern Australia is an area simply known as “the abyss.” The largest and deepest habitat on the planet, the abyssal zone stretches well beyond Australia’s waters and spans half the world’s oceans — but it remains largely unexplored. Continue reading
In our book, lost and found is normally half glass full (versus half empty) new that we enjoy sharing, and this one counts as more than half full due to the intrigue of the history and the odd charisma of the creature:
On June 27, 1824, a trading vessel en route from Mauritius to England was caught in a powerful gale. For ten days, winds pounded the King George IV until it could no longer hold together. In three perilous traverses, a small rescue boat shuttled those aboard to a beach near the Cape of Good Hope. “Neither myself nor the passengers have saved a single article,” the captain later wrote. “Probably they may cast up in time.” Amid the lost cargo—mostly sugar, cotton, and cloves—were three cases of scientific specimens. Continue reading
Lewis Lapham has shown up in our pages here exactly once in the past. Mainly because, in the six years we have been posting on this platform, his own publication was not as accessible as others we have been linking to. Surely there was a purpose to the walls constructed around it, but we are happy that, for whatever reason, they have come down. Just the illustration above and the quotations below should make you want to read more:
Evolution has arranged that we take pleasure in understanding—those who understand are more likely to survive.
I’m sorry I know so little; I’m sorry we all know so little. But that’s kind of the fun, isn’t it?
We sample the opening two paragraphs after the jump below, and recommend savoring his writing, but we also have been on the podcast bandwagon since we started on this platform. If you have already been enjoying Lewis Lapham’s publication, and wishing it were available in an audible format, today is your lucky day (click the soundcloud banner here to listen).

Thanks to Brandon Keim and Anthropocene for this summary of some recent science exploring the reactions of flora to sound in their search for water:
There’s a transformation underway in how people think about plants: not just as inanimate biological objects, but as capable of perceptions and actions that resemble the intelligent behaviors of animals. Continue reading
While I personally don’t focus on organized religion, I can’t deny the power of sacred music to uplift my spirit. This story of inspired Renaissance composition and modern-day curiosity resonates with historical sleuthing and musical puzzle solving.
Click on the Sound Cloud musical links, close your eyes and breathe deep.
Eight years ago, leafing through a bibliography of 16th-century music prints (like you do), my eye was caught by the title of a motet: “Salve sponsa Dei.” “Bride of Christ,” I thought. “Must be for nuns!”
It was one of 23 anonymous motets published together in 1543, so I did what any self-respecting nunologist would do, and ordered a reproduction of the book. As I put the motets into a usable edition for modern singers, I found they were unlike any other 16th-century music I’d ever seen. They were dense, intense and sometimes startlingly dissonant.
The music – for five equal voices (of unspecified sex) – is astonishingly beautiful and yet strange, radical even. These works had lain unsung and unloved for almost four centuries, mostly because they were anonymous. These days, anonymity suggests that whoever created the book, music, painting or whatever was not important enough, or the product is not good enough, for anyone to care who made it. But in the 16th century, anonymity was also an important way for members of the nobility to disguise their participation in commercial ventures that were considered beneath them (which is why Gesualdo, a prince, published his madrigals anonymously).
But Virginia Woolf was right when she said: “Anonymous was a woman.” Continue reading
