Voices of GLBT scientists

For a broader perspective on being gay and being a scientist, check out some great pieces on BoingBoing, posted for National Coming Out DaySteve Silberman interviews endocrinologist Neena Schwartz about her decision to come out after a career in the closet; then Maggie Koerth-Baker rounds up personal stories from an array of LGBT scientists, including evolutionary biologist Douglas Futuyma. As Maggie puts it in the introduction to both articles,

Together, we realized that we’d never seen a Coming Out Day feature dedicated to the experiences of lesbians, gay men, bisexuals and transgendered persons in the sciences and engineering. Science journalist powers: Activate! We hope today’s two-part celebration will add to the diversity of stories and help science-minded young queer folks everywhere know that it does, indeed, get better—both through the course of history, and the course of an individual’s life.

Other queer scientists are invited to contribute stories in the comments of Maggie’s piece. (Maggie asked me to help contact people to share their stories, and I put her in touch with Dr. Futuyma; and Steve was kind enough to give me a nod at the end of the cross-post of his interview with Neena Schwartz.)

Why I’m out online

ResearchBlogging.orgExactly a year ago today, I came out of the online closet. Now it’s another National Coming Out Day, and it seems like as good a time as any to think out loud about why I made that decision.

Image borrowed from Wikipedia under fair use rationale.

My reasons aren’t going to surprise anyone who has even a passing familiarity with gay rights history:

  • Familiarity breeds acceptance. This is mainly a political argument. It’s widely accepted (and supported by ongoing public opinion surveying) that people who personally know GLBT folks are overwhelmingly more likely to support treating GLBT people like full citizens. The psychology isn’t hard to understand—it’s easy to hate the nebulous, faceless, unknown Gays; it’s rather harder to hate your son, or your niece, the nice neighbors who let you borrow their lawnmower, or (I hope) the guy who writes that one not-entirely-terrible science blog you check every so often.
  • Gotta give’em hope. And an example. This is more personal. I grew up without knowing any out gay people, which was, to put it mildly, not helpful. I was, to paraphrase the Onion headline, The Only Homosexual in the World; I didn’t have any of the support, or visible examples, that would’ve helped me think critically about my sexual orientation or imagine a future in which I was out, and happy about it. (Which I very much am, these days.) By being open about my orientation, maybe I can help someone else figure out his (or hers) in a way I couldn’t, and even show that, as confusing and frequently miserable as growing up gay is, it gets better.

And if there’s one impression I hope to give a confused, lonely (and presumably nerdy) gay kid reading D&T, it’s that it did get better for this formerly confused, lonely (and unquestionably nerdy) gay kid. And a large part of how it got better, for me, has to do with going into science.

Evolutionary biology has turned out to be a good field for me, in this personal respect. When I started my first genuine biology-related internship, I was surrounded for the first time by people who didn’t talk about gays in the hushed, scandalized tones I’d heard through a lot of my childhood and schooling. Biologists are as human as the next ape descendent, but they’re also a generally open-minded bunch who tend to be more interested in the quality of your work than what you do after you leave the lab. And, for what are probably obvious reasons, evolutionary biology doesn’t attract the sort of people who hold doctrinaire conservative religious positions on any subject.

Evolutionary biology is also a pretty good academic discipline for me because evolutionary biology has something to say about sexual minorities, just as it has something to say about humans in general. Humans are biological beings, and we’re part of an animal kingdom that exhibits a wide array of sexual behaviors, as elaborately documented by the evolutionary biologist Joan Roughgarden in her book Evolution’s Rainbow. Exactly how to explain this diversity, particularly in the case of humans, is still quite controversial [$a]—but it’s a question for which I have some expertise, and one I’d like to weave into the writing I do for D&T in the future.

Time to start thinking about #scio11 already?

Science Online 2011, the conference for online science communication, now has a website, and NESCent, whose blog writing competition helped me attend Science Online 2010, has announced another round. I’m going to sit on my hands and let someone else have a chance for a change, but I’ll bet I can wrangle a grant from U of I’s grad student association to get me to North Carolina next January …

The kids aren’t all right: Brood parasite chicks grow up with species identity issues

ResearchBlogging.orgIf you’re a bird, brood parasitism seems like a cushy reproductive strategy—lay your eggs in someone else’s nest, then sit back and let the inadvertent foster parents raise your kids for you. But what if they don’t raise you kids quite right? Could brood parasite chicks raised by parents of another species grow up a bit … confused? According to a recent study of brood-parasitic ducks, they can indeed [$a].


Redheads (above) sometimes lay eggs in the nests of canvasback ducks (below)—but redhead chicks raised by canvasbacks may not know what species they are. Photos by Nick Chill and meantux.

The new study examines redheads, a species of North American duck which frequently lays its eggs in the nests of other duck species, particularly the canvasback duck, which occupies much of the same range. Redheads are facultative brood parasites—in years when conditions produce lots of resources, female redheads lay eggs in other ducks’ nests as a supplement to their own nests; and in poorer years, they may lay only parasitic eggs [PDF]. Canvasback ducks, on the other hand, will lay eggs in the nests of other canvasbacks (which is not uncommon in birds [$a]), but don’t parasitize other species.

This sets up a nice behavioral experiment. In birds, species recognition may be due to varying degrees of nature and nurture—a male bird may recognize females of his own species by genetically-transmitted instinct, but he may also have to learn socially important songs or other behaviors from his parents and other adults. You might expect that redhead chicks have evolved to recognize their own species regardless of who raised them, while canvasbacks might be confused if they grow up around another species.

So the authors experimentally transferred just-hatched male redhead chicks into canvasback broods, and male canvasback chicks into redhead broods, and compared their social development to male chicks raised by their own species.

When the chicks had grown up, the authors offered the cross-fostered males access to females of both species, and recorded their interactions. It turned out that the brood parasitic rednecks were just as prone to species-confusion as the canvasbacks. Males of both species preferred to associate with females of the species with which they were raised, and directed almost all of their courting effort—displays of neck-arching and special calls—toward the species that fostered them. In fact, many of the cross-fostered males successfully formed mated pairs with females of the other species.

So why hasn’t redhead parasitism of canvasback nests broken down the reproductive isolation between these two species? The authors don’t have a clear answer, but note that the rate of observed hybrid couplings are much lower in natural populations than in their experimental setting. Social learning is a complicated thing, and life in larger, natural populations of the two species might not be well replicated in this study.

The Molecular Ecologist

The journal Molecular Ecology Resources, a methods-focused offshoot of Molecular Ecology, has just launched an official blog, The Molecular Ecologist. One of the contributors is Dilara Ally, who until quite recently was one of my colleagues at the University of Idaho Department of Biological Sciences. From the first few posts, it looks like TEM will be a good resource for working biologists, who are the target audience.
