We linked to one of Richard Prum’s books more than four years ago, then he was mentioned in a couple posts, each with small quotes based on his expertise. Here he is in conversation with someone who clearly appreciates his work and who knows how to ask good questions:
Richard Prum really cares about birds. Growing up in rural Vermont, he didn’t know anyone else interested in birding his own age. The experience taught him to rely on his own sense of curiosity and importance when deciding what questions and interests are worth studying. As a result, he has pursued many different paths of research in avian biology — such as behavioral evolution, where feathers come from, sexual selection and mate choice — many of which have led to deep implications in the field. In 2017, Tyler agreed with several prominent outlets that Prum’s book The Evolution of Beauty was one of the best books of the year, writing that it “offers an excellent and clearly written treatment of the particulars of avian evolution, signaling theory, and aesthetics, bringing together some disparate areas very effectively.” Continue reading

Protecting species from extinction has been a running theme in our pages over the years. Underlying these many stories was an assumption, at least on our part, that defining boundaries between species is settled science. We will no longer take that for granted:
Thanks to Robert Moor for these reviews:
Two new books, Edith Widder’s “Below the Edge of Darkness” and Helen Scales’s “The Brilliant Abyss,” explore the darkest reaches and all that glows there.
In the deep sea, it is always night and it is always snowing. A shower of so-called marine snow — made up of pale flecks of dead flesh, plants, sand, soot, dust and excreta — sifts down from the world above. When it strikes the seafloor, or when it is disturbed, it will sometimes light up, a phenomenon known, wonderfully, as “snow shine.” Vampire squids, umbrella-shaped beings with skin the color of persimmons, float around collecting this luminous substance into tiny snowballs, which they calmly eat. They are not alone in this habit. Most deep-sea creatures eat snow, or they eat the snow eaters.
Until fairly recently, it was widely believed that the deep seas were mostly devoid of life. For centuries, fishermen hauled in deep-sea trawling nets filled with slime, not knowing that these were carcasses. Some animals, adapted to the pressure of the deep, are so delicate that in lighter waters a mere wave of your hand could reduce them to shreds. The myth of the dead deep sea, known as the Abyssus Theory, was disproved by a series of dredging and trawling expeditions in the 19th century, including a German scientific expedition in 1898 that pulled up the first known vampire squid. But the misconception nevertheless lingered. In 1977, a geologist piloting a submersible near the mouth of a hydrothermal vent, and finding it swarming with creatures, asked the research crew up above, “Isn’t the deep ocean supposed to be like a desert?” Continue reading

Nothing like bioluminescence to take your mind off of other things for a while. Thanks to Yale e360 for this:
In an interview with Yale Environment 360, marine biologist Edith Widder talks about her pioneering research into the world of bioluminescent organisms in the deep oceans and warns of the dangers, from trawling to oil drilling, that imperil this hidden realm.
Atolla vanhoeffeni, a bioluminescent deep-sea jellyfish. EDITH WIDDER
Until recently, the depths of the world’s oceans remained almost entirely unexplored. But advances in submersible technology are increasingly giving scientists a window into this little-known universe. One of the leaders in this exploration is marine biologist Edith Widder, who has extensively studied bioluminescent, or light-producing, organisms that use this trait to communicate, defend themselves, and hunt in darkness. Among other things, Widder has worked with engineers to develop highly sensitive deep-sea light meters and special cameras, like the remotely operated Eye-in-the-Sea, which allow for real-time monitoring of the seafloor.

The author has been featured in these pages multiple times over the years. The publisher makes it easy to find an option that suits your shopping preferences (our preference is obvious). Her new book has received plenty of praise, according to an email she sent us:

We were aware that birds will build nests out of just about anything they can find, and sometimes in the strangest places. But how they get the material is less familiar, and in the article below is a video of a bird plucking fur from a fox, about as fun to watch as anything we have seen recently, so click through to the full story:
It’s simple: Mammals have hair or fur. Birds want it.
As anyone who has ever tried to eat french fries on a beach will attest, stealing is not an uncommon behavior among birds. In fact, many birds are quite skilled at bold and brazen theft. Continue reading
I missed this book when it was first published, but thankfully its author was invited onto a podcast I listen to regularly.
On the author’s own website she links an independent bookseller of her choice as the favored place to buy the book. Bravo.
Klein’s introduction to the conversation:
I’ve spent the past few months on an octopus kick. In that, I don’t seem to be alone. Octopuses (it’s incorrect to say “octopi,” to my despair) are having a moment: There are award-winning books, documentaries and even science fiction about them. I suspect it’s the same hunger that leaves many of us yearning to know aliens: How do radically different minds work? Continue reading

Arctic bumblebees came to our attention nearly five years ago, and this story below reminds us that while climate change is not a zero sum game–it is more like a game of perpetual loss, which is more like what we have witnessed with bees in general–there are some winning adaptations in some locations:
Michelle Nijhuis is one of several science writers who have made our pages better in the 10 years since we started this platform. This essay is in good company:
As climate change intensifies and human activity impacts every corner of the planet, repairing our world increasingly means realizing that our fate is intertwined with that of other animal and plant species — not separate from theirs — and that we must think and act accordingly. Continue reading
Common black ant (Lasius niger) workers and three queens.
Any given day in Costa Rica the number of insects one is likely to encounter is too great to count. Ants are not automatically loved, but they are respected. Brooke Jarvis, whose writing we saw primarily in the New Yorker previously, has spectacular photography to accompany her text in this New York Times article in the Science section:
Even in the densest human habitations, there are orders of magnitude more ants than there are of us, doing the hard work of making our crumbs disappear.
It is telling, the entomologist Eleanor Spicer Rice writes in her introduction to a new book of ant photography by Eduard Florin Niga, that humans looking downward on each other from great heights like to describe the miniaturized people we see below us as looking “like ants.” By this we mean faceless, tiny, swarming: an indecipherable mass stripped of individuality or interest.

Intellectually, though, we can recognize that each scurrying dot is in fact a unique person with a complicated and interconnected life, even if distance appears to wipe away all that diversity and complexity. Continue reading

Our attention to eels is only occasional, but the mysteries keep coming. The article contains an amazing video of this pack-hunting phenomenon. Thanks to Annie Roth for this:
The behavior, used by wolves and orcas to run down fast prey, is rarely seen in fish.
In August 2012, Douglas Bastos, then a graduate student at Brazil’s Instituto Nacional de Pesquisas da Amazônia, was exploring a remote waterway in the Amazon rainforest when he came across a small lake teeming with electric eels. Continue reading
If you can suspend judgement for a moment the awe is overwhelming:
Odin, in Norse mythology, is an extremely powerful god who’s also a trickster. He has only one eye, having sacrificed the other for wisdom. Among his many talents, he can wake the dead, calm storms, cure the sick, and blind his enemies. Not infrequently, he transforms himself into an animal; as a snake, he acquires the gift of poetry, which he transfers to people, inadvertently.
The Odin, in Oakland, California, is a company that sells genetic-engineering kits. The company’s founder, Josiah Zayner, sports a side-swept undercut, multiple piercings, and a tattoo that urges: “Create Something Beautiful.” He holds a Ph.D. in biophysics and is a well-known provocateur.

Cara Giaimo, as ever providing surprising explanations of natural phenomena, has this biology lesson for a holiday tradition:
Today’s post is a finding from the natural world that intersects with the premise of a favored book for kids:
Before metamorphosis, monarch butterflies will aggressively head butt each other for access to their favorite food.
In the 1969 children’s book “The Very Hungry Caterpillar,” the tiny protagonist spends a week snarfing his way through a smorgasbord of fruits, meats, sugary desserts and, finally, a nourishing leaf. This family-friendly tale was missing one crucial and far less G-rated plot element: the pure, unadulterated rage of an insect unfed. Continue reading
The Science section of the Guardian’s website has an article profiling an author and his new book (click above to find the book on the author’s website) that relate to a topic we care about as much as any we post about on this platform.

When Amie and Milo and I moved to Kerala, India in 2010 it was ostensibly for the sake of our client. But it was also for Milo. He was 16 years-old with a strong interest in mycology, and was motivated to translate his knowledge into practice. Within the first year he set up a small farming operation for culinary mushrooms.

He was adept at explaining the importance of complex networks like those in the image to the left, and made me a believer: the future is fungal, for culinary, medicinal, and bio-remediation purposes. When restoration of this coffee farm started, I built a berm with logs at the core, expecting a mycelium network to develop, creating a healthy border for the shade trees planted.
These days Milo has his own forest tract to continue these pursuits and I keep a lookout for related stories of interest. Merlin Sheldrake has my full attention today:
The study of fungi has long been overshadowed by more glamorous scientific quests. But biologist Merlin Sheldrake is on a mission to change that

As a boy, Merlin Sheldrake really loved the autumn. In the garden of his parents’ house – he grew up a few moments from Hampstead Heath, which is where he and I are walking right now, on an overcast summer morning – the leaves would fall from a big chestnut tree, forming gentle drifts into which he liked nothing more than to hurl himself. Wriggling around until he was fully submerged, Sheldrake would lie there, quite content, “buried in the rustle, lost in curious smells”. As he writes in his wondrous new book, Entangled Life, these autumnal piles were both places to hide and worlds to explore. Continue reading
Bees, in all their surprising ways, are important to humanity, so we share science about them. Our thanks to one of science writing’s most deft explainers, James Gorman, for one more insight. If only for the video, showing the precision of the bee’s ability to drink nectar, this article is worth a look:
Once again, insects prove to be more complicated than scientists thought they were.
For a century, scientists have known how honeybees drink nectar. They lap it up.
They don’t lap like cats or dogs, videos of whose mesmerizing drinking habits have been one of the great rewards of high speed video. But they do dip their hairy tongues rapidly in and out of syrupy nectar to draw it up into their mouth. For the last century or so, scientists have been convinced that this is the only way they drink nectar. Continue reading

This book (click the image to the left to go to the publisher) has become an unexpected bestseller. The other times we have posted on the topic of eels, a couple of them were artistic in nature and the other were scientific in nature. I would not have predicted that a whole book on the topic was something I would want to read, let alone that a very sizable audience would develop. I would expect that if there were to be more than four posts mentioning eels in the nine years we have been posting, we might have covered the topic of aquatic agriculture. But, no.
When I listened to a conversation (click the image to the right to go to the podcast) with the author of The Book of Eels it reminded me that I had already read a review of the book by Brooke Jarvis a few months earlier. And that we should post more on eels The illustration adorning the review was fun. The opening paragraphs were compelling:
The mysterious creature has attracted avid detectives since ancient times. Illustration by Jason Holley
In the spring of 1876, a young man of nineteen arrived in the seaside city of Trieste and set about a curious task. Every morning, as the fishermen brought in their catch, he went to meet them at the port, where he bought eels by the dozens and then the hundreds. He carried them home, to a dissection table in a corner of his room, and—from eight until noon, when he broke for lunch, and then again from one until six, when he quit for the day and went to ogle the women of Trieste on the street—he diligently slashed away, in search of gonads.
