Portal back in time contains agrobiodiversity

Sure, the story of the sinkhole with 12,000 years’ worth of clues about the life of some of America’s first residents is fascinating. But what we all want to know is what kind of gourd is it, exactly?

All you can eat

Is there any ethnic food concoction that says (agro)biodiversity quite like smÃ¶rgÃ¥sbord?

LATER: With vodka, of course.

Rainbow breeds

All of these variants in color should be noted and celebrated, but should also be guarded by the breeders to be certain that all of them can be available to future breeders. Past breeders bequeathed this wealth of variation and adaptation to the present generation â€“ and it is important that each generation guard the resource and present it to the next generation as a useful and viable genetic resource.

Virtual visit to VIR

Click on the picture for some impressions from my recent visit to the N.I. Vavilov Institute Research Institute for Plant Industry in St Petersburg, Russia on the occasion of a SEEDNet meeting. A veritable monument to agrobiodiversity. And don’t forget Nikolai Ivanovich has a voice.

A neck bred for biting

Quick, what do you think of when I say “Transylvania”? Right. And where do vampires generally bite? Right again: on the neck. So, what are we to make of a breed of chicken called the Transylvanian Naked Neck? That is was bred to be bitten?

I think not. Naturally I was more than piqued when I saw Transylvanian Naked Neck in the subject line of a mailing list Luigi hangs out on. Ugly buggers, we both agreed, but one fancier swears that “over a dozen hens have chosen Turkey-Neck ¹ as their heart-throb. We think this is because he’s gentle with girlfriends and very stern with younger, oversexed roosters.” The condition is apparently the result of a single gene that “affects the arrangement of feather-growing tracts over the chicken’s body”. Indeed, it reduces the density of feathers all over the chicken, “but this is not evident until the bird is handled”. The lack of insulation means that naked neck breeds should be given extra protection against low temperatures, but that “does not detract from the utility of the bird”.

As for the original discussion, it ended with reference to a paper Prospects for conserving traditional poultry breeds of the Carpathian Basin in which the Transylvanian Naked Neck is just one of the breeds considered. There’s a bunch of stuff in there about why the breeds are valuable and how they’re being conserved, and lots of pictures. But not an answer to the fundamental question: What (if any) evolutionary value does a naked neck give its holder? Probably none. And if they suffer more in cold weather it could even be harmful, but at least some people, and not just photophobic immortals, find them attractive. Which is a good enough reason to conserve them. Luigi reckons they probably taste good too.
