Nibbles: Introgression in sorghum, British cheese, Cassava development, Fishing

  • “Farmers have quite accurate perceptions about the genetic nature of their sorghum plants, accurately distinguishing not only domesticated landraces from the others, but also among three classes of introgressed individuals, and classing all four along a continuum that corresponds well to genetic patterns. Their practices are fairly effective in limiting gene flow”
  • Cheese map of Britain. Had no idea there was a National Cheese. I always liked Wensleydale.
  • “I harvested part of the cassava and transported it to the nearest processing centre, where it was peeled, washed, pressed, dried and milled into cassava flour. They charged me Tsh600 per kilogramme (about half a dollar) and the market price was Tsh380 a kilo.”
  • The giant Ponzi Scheme that is modern fishing.

Andy Jarvis in the limelight

Our friend, colleague and occasional contributor Andy Jarvis received GIBF‘s Ebbe Nielsen Prize for innovative bioinformatics research last night in Copenhagen. Andy has been doing his trademark work on the spatial analysis of crop wild relative distributions ((The maps below are an example. They show the modeled distribution of species richness in the genus Phaseolus now, and then in 2050.)) at CIAT, just outside Cali in Colombia, jointly with Bioversity International. He used the occasion to highlight the contribution made to this effort by his numerous Colombian colleagues. Congratulations to all of them.

Mapping free fruit

Free-fruit enthusiasts have put together a Google Maps application to help them forage. Only has a few sites around Britain and Germany at the moment, but I bet it will grow.

Would it be so difficult to have something similar to report threats of genetic erosion, for example? I know Jacob thinks that would be useless, as a threat is only really a threat if it is likely to have an effect on overall genetic diversity, not just on what is available locally. But I’m not so sure. And it would be fun to do.
