Nothing in Biology Makes Sense: Tropical trees, getting by with a little help from their mutualistic ants

This week at Nothing in Biology Makes Sense! I’m discussing a nifty new study that suggests interacting species can sometimes tolerate stressful environments by helping each other out:

This was the perspective of Peter Kropotkin, a Russian prince and political anarchist who studied the wildlife of Siberia while working as an agent of the Czar’s government. In the harsh conditions of the Siberian winter, Kropotkin reported finding not a bitter struggle over scarce resources, but what he called “Mutual Aid” among species, as well as in the human settlements that managed to eke out a living.

Something like what Kropotkin described is documented in a new paper by Elizabeth Pringle and colleagues. Examining a protection mutualism between ants and the tropical Central American tree Cordia alliodora, Pringle et al. found that drier, more stressful environments supported more investment in the mutualism.

To learn how ants can help a tree deal with drier climates—no, it doesn’t involve little tiny bucket brigades—you’ll have to go read the whole thing.◼

Queer in STEM on Autostraddle

My collaborator on the Queer in STEM project and I are flattered to be the subjects of an entire profile over at Autostraddle, part of the great series on “Queered Science” by Vivian Underhill, who also gave us a nice nod in an article for Bitch Magazine. The Autostraddle article gets into the genesis of the project:

Allison had done some work on queer issues previously, on “discrimination in school settings, transnational queer migration, and identity development.” So Jeremy asked Allison what she thought about the idea of a survey of a nation-wide sample of queer scientists – as a social scientist, did she think results like that would be publishable? “I responded, ‘are you asking me to teach you about doing research with human subjects? Sure!'”

There’s even an artist’s rendering of us hard at work in the field:

  • This week at Nothing in Biology Makes Sense! Lizards that adjust their development for their habitat based on the temperature outside their eggs.
  • You’ll laugh, you’ll cry, you’ll hopefully learn a little about harassment and how to stop it. Hope Jahren sure can write.
  • Color me not surprised, still unhappy to see it. There’s a gender gap in citation counts.
  • Plants versus everyone else. The not-so-hidden chemical warfare agents of the vegetable aisle.
  • “Use the left lane for passing, Mr. Sulu.” What an Alcubierre warp-drive spacecraft would look like on its way past.
  • Hmm. Should peer reviewers review methods even before the experiments are done?
  • Welcome to the hominid family! On that new, impressively complete skull of an early Homo species.
  • Bookmarking for (hopefully not too much) later. How life as a professor isn’t like anything you’ve done before.

Nothing in Biology Makes Sense: Incubation temperature tailors these skinks to their habitat

This week at Nothing in Biology Makes Sense, there’s a post from yours truly about a curious case of developmental flexibility in some Australian lizards. It seems that rainbow skinks (Carlia longipes) develop bigger bodies and longer legs if they’re incubated in cooler nests—and those developmental changes provide an advantage in the rocky habitats where nest temperatures are typically cooler:

Life is risky for a newly hatched lizard. You have to make your way in a habitat you’ve never seen before, full of all sorts of larger animals that think you’d make a decent snack, if maybe not a full meal. Wouldn’t it be nice if you could’ve been preparing for the conditions you’ll meet out there even before you crack through that shell?

Well, for one species of skinks, it looks like this may be exactly what happens. A recent paper in The American Naturalist makes the case that rainbow skinks (Carlia longipes) develop in their eggs to match the habitat conditions around their nest—based on the temperature of the nest.

This is a classic case of phenotypic plasticity, in which development responds to the environment to provide a better fit—but in Carlia longipes, plasticity goes beyond growing longer legs. To find out what’s up with these skinks, go read the whole thing.◼

Science online, what is this I can’t even edition

So this week, these things happened: Biologist and Scientific American blogger Danielle N. Lee called out a deeply disrespectful editor at the website Biology-Online, only to have SciAm take down her post. In response to widespread outrage and agitation, SciAm‘s editor-in-chief relented and more-or-less apologized.

And then Monica Byrne and Hannah Waters came forward to report that Bora Zivkovic—the SciAm blogs editor, co-founder of the ScienceOnline conference, series editor of the Open Lab anthology, and all-around godfather of online science communication—had sexually harassed them. Bora’s confirmed Monica Byrne’s report, apologized, resigned from the board of ScienceOnline, and is apparently taking leave from SciAm.

Not a good week for some leading institutions of science outreach—but also, one hopes, the first steps toward doing better.

Also these things:

Nothing in Biology Makes Sense: Circumcision and microbial ecology

Banana Peel What? Photo by photograφ.

Over at Nothing in Biology Makes Sense!, Sarah Hird describes a new study of what happens to the microbial community of the human penis when you make a … let’s say a certain change to its environment?

They begin by sampling the penile microbiota of 156 uncircumcised men. Approximately half of the men are then circumcised and all subjects are resampled after one year (presumably enough time that behavior is unaffected by the procedure).

Yeah, it’s maybe not surprising that circumcision would change what kinds of bacteria hang out in the region formerly covered by the foreskin. But apparently that change may contribute to the reduced rate of HIV transmission associated with circumcision. To find out how, go read the whole thing.◼

  • This week in shutdown science: The CDC sits out an outbreak of drug-resistant salmonella, experiments on hold, lab mice euthanized and an entire season of Antarctic research cancelled.
  • Not like they have much state funding to lose, these days. Public universities are looking for ways to be less, um, public.
  • Of course, it can be both! Is behavioral genetics “taboo,” or just bad science?
  • From the personal to the general. The New York Times Magazine goes in-depth on underrepresentation of women in science.
  • Because bunnies! The Central Limit Theorem turns out to be adorable.
  • This sounds … familiar. The Great Library of Alexandria wasn’t destroyed by a fire, but by budget cuts.
  • Literally, because he says he can’t. Why Malcolm Gladwell can’t be trusted.
  • About 35 years. A new study estimates how long global warming can continue before average temperatures exceed historical highs.
  • It’s more likely to be MRSA. No, that’s almost certainly not a brown recluse bite.

The Molecular Ecologist: Is Homo sapiens a model organism?

Over at The Molecular Ecologist, guest contributor Jacob Tennessan suggests that for those of us who study the genetics of natural populations, the ultimate “model organism” may be … us.

Thus, the field of human population genetics has always been a step or two ahead of the molecular ecology of wildlife. Common techniques like mitochondrial- or microsatellite-based phylogeography analyses were pioneered with data from humans. Research into human molecular ecology has yielded countless fascinating stories that provide a baseline for what to expect when examining other taxa. Some are well-known textbook examples, like the sickle-cell hemoglobin balanced polymorphism that conveys resistance to malaria, or the human global diaspora reflected in sequence diversity that traces back to “mitochondrial Eve” and “Y-chromosome Adam.”

Does that make Homo sapiens a “model organism” in the same sense as fruitflies and Caenorhabditis elegans, or more of a proving ground for new molecular methods? Go read the whole thing, and tell us what you think in the comments.◼
