Octopuses Host a Masterclass on Hiding

by Elizabeth Preston in Inkfish





When you're surrounded by an ocean full of potential predators, the best way to avoid seeing the inside of one's stomach is to make sure none of them see you in the first place. Octopuses and some other cephalopods are experts at camouflage, manipulating the colors and textures of their skin to hide in plain sight. But their strategy, it turns out, has nothing to do with disappearing into the background.

To learn the camouflaging secrets of the masters, researchers led by Noam Josef at Ben-........ Read more »

When introductions go bad

by Sarah Stephen in An ecological oratorio

My first sighting of the red squirrel was in Camperdown Park in Dundee in 2003. I remember that scene vividly. I had since tried desperately to see this elusive animal again but to no avail, save a brief sighting, again in Camperdown Park, in Autumn 2010. This is because although red squirrel, which is native to UK and  is  protected in Europe, is outnumbered by its foreign relative, the grey squirrel that was introduced to the UK from America. G........ Read more »

Snakes Deceive to Get a Little Snuggle

by Miss Behavior in The Scorpion and the Frog

A lone red-sided garter snake. Photo by Tracy Langkilde.The red-sided garter snake is a small snake species with the largest and most northern distribution of all reptiles in North America. These northern ranges can get quite cold for any animal, let alone a reptile. Like most reptiles, they are ectotherms, meaning they regulate their body temperature largely by exchanging heat with their environment. If an animal gets almost all of its body heat from a cold environment, its body is also going t........ Read more »

Rattling Nature’s Chains

by gunnardw in The Beast, the Bard and the Bot

To start with a cliché: in nature, everything is connected. Organisms are eaten by each other, waste material (including dead organisms) is used by others, and the impact of animals, plants and other life forms on the environment alters their … Continue reading →... Read more »

Having a Water Bottle for a Mom Not Ideal

by Elizabeth Preston in Inkfish




In the wild, young rhesus macaques can reasonably expect not to have their mothers replaced by kitchen props. The monkeys depend on their moms to nurse them and tote them through tree branches while they're small, just like other primates. But a laboratory experiment in Maryland took these babies from their mothers and had them raised alone or in groups of their peers. The monkeys' strange infancies had physical and mental effects that lasted into adulthood.

At the National Institute of Chil........ Read more »

Phosphorus, detergent, and Canada's Experimental Lakes

by Patrick in Evidence and Error

“I'm angry at the people who decided that phosphate was growing algae. I'm not sure that I believe that.”  –Sue Wright, Texas

Sue Wright, quoted above, was upset because in 2010, sixteen American states banned the sale of dishwashing detergent containing high levels of phosphorous, an aquatic pollutant that sometimes causes eutrophication (algal blooms). Unfortunately, phosphorous is a rather effective component of detergent, so phosphorous-free dishwashing detergents did not immediate........ Read more »

The Secret to Success Is Giant-Jawed Snake Babies

by Elizabeth Preston in Inkfish




When coming face-to-face with a wriggling, freshly born pile of poisonous snakes, most of us wouldn't linger for a close look. But it was by looking into these living linguini platters that one biologist found a new answer to an old question: Why does island life make animals such freak shows?

Some big-bodied species shrink when they move from the mainland to an island habitat, a phenomenon that's created pygmy sloths, miniature mammoths, and possibly even a dwarf hominid that's now extinct......... Read more »

Decay Fungi: Eaters of Forests, Painters of Wood

by Kimberly Gerson in Endless Forms Most Beautiful

Decay fungi are generally disdained, but wood is held in high regard. The meeting of both can create emotional conflict and challenges the viewer to reevaluate their position on functional wood and natural ornamentation processes. – Dr. Sara C. Robinson Gene handed me a small block of maple, maybe an inch across. “This is spalted [...]... Read more »

■ Urban trees reveal income inequality

by Tim De Chant in Per Square Mile

Wealthy cities seem to have it all. Expansive, well-manicured parks. Fine dining. Renowned orchestras and theaters. More trees. Wait, trees? I’m afraid so. Research published a few years ago shows a tight relationship between per capita income and forest cover. The study’s authors tallied total forest cover for 210 cities over 100,000 people in the [...]... Read more »

Genomics, Open Access, and China

Does Social Status Change Brains?

by Miss Behavior in The Scorpion and the Frog

Photo by The Grappling Source Inc. at Wikimedia CommonsBeing subordinated is stressful. The process of one individual lowering the social rank of another often involves physical aggression, aggressive displays, and exclusion. In addition to the obvious possible costs of being subordinated (like getting beat up), subordinated individuals often undergo physiological changes to their hormonal systems and brains. Sounds pretty scary, doesn’t it? But what if some of those changes are beneficial in ........ Read more »

Plastic Seas

by GunnarDW in The Beast, the Bard and the Bot

There is a lot of plastic in the world’s oceans. This is widely known, even though it’s a fairly recent development, tracing back a few decades. Most of this plastic, however, is quite small and, as such, is known by the name microplastic (diameter below 5 mm).

For a while now, it has been known that this is not a good thing (mild understatement). ... Read more »

In the Spring, Bat Moms Choose Girls

by Elizabeth Preston in Inkfish




Naturally a mother bat is happy to welcome into the world a bouncing baby whatever, as long as it has all its fingers and toe-claws. But she also wants her little one to have every advantage she can give it. So when spring comes early, big brown bats prefer to keep their female embryos. Unwanted males are reabsorbed into their mothers' bodies as if they never existed.

University of Calgary biologist Robert Barclay learned the bats' secret by spying on three colonies living in the charmingly ........ Read more »

■ Farming, circa 2050

by Tim De Chant in Per Square Mile

Farms today look nothing like the farms of 40 years ago. Thanks to market and policy changes along with advances in technology, they’re larger, more mechanized, and more intensive. And while those factors will likely continue to affect farmers, there’s another looming on the horizon—climate change. Agriculture has already seen the effects of a warming [...]... Read more »

Buzz Kill? Bee Populations and Pesticides

by Whitney Campbell in Green Screen

A swarm of studies have recently been released concerning Colony Collapse Disorder (CCD), and considering the serious implications of their findings, it's all of our beeswax. These experiments, including two published in Science1,2 and one forthcoming from the Bulletin of Insectology,3 demonstrate the threat to hive survival stemming from a class of insecticides called neonicotinoids. Individually, I think each study is convincing, but when taken together, the consensus provides overwhelmin........ Read more »
