- Diversity and heritability of the maize rhizosphere microbiome under field conditions. There’s a lot of it, but only measured in inbreds so far. One wonders about landraces.
- The Vulnerability of Biodiversity to Rapid Climate Change. We should focus on increasing the adaptive capacity of species and ecosystems, but predictions are difficult, especially about the future.
- The Capsella rubella genome and the genomic consequences of rapid mating system evolution. Sex is better with two.
- Progress Toward Understanding Heterosis in Crop Plants & Genomic and epigenetic insights into the molecular bases of heterosis. It’s the allelic interactions, stupid. Now to make use of this.
- Deforestation in an African biodiversity hotspot: Extent, variation and the effectiveness of protected areas. Protected areas have worked for the evergreen forest, but don’t forget the miombo! Would be intersting to know what this all means for crop wild relatives.
- Comprehensive genotyping of the USA national maize inbred seed bank. Ladies and gentlemen, I have seen the future of genebanks.
The state of chickens
Luigi pointed me to a nice graphic poster of the officially approved bird for all 50 of the United States. Among them, I noticed two chickens, for Delaware and Rhode Island. Rhode Island might seem obvious enough, the Rhode Island Red being almost the canonical farmyard bird.
But Delaware, not so much.
In fact Delaware was one of the biggest poultry and egg producing states in the Union. Sussex County DE, where the modern broiler industry began, still holds the record for egg and poultry sales, “with $707 million, or 1.9 percent of the total U.S. value” in 2007. That’s almost 2% of the value from 0.024% of the land. But Delaware’s state bird – the Blue Hen Chicken – is not one of the squillions (many of them carrying Rhode Island Red genes, I’ll warrant) that contribute to Sussex County’s top cock status. It isn’t even a real breed. 1
Nope; apparently Delaware’s blue hen chicken is a reminder of the Revolutionary War. Exactly how remains uncertain. Cock-fighting was common there at the time, and the Delaware Regiment may or may not have carried feisty blue gamecocks into battle, may or may not have been as feisty as a blue gamecock, and may or may not have looked like a flock of feisty blue gamecocks in their natty uniforms. There is a flock of blue hen chickens at the University of Delaware, whose mascot is the blue hen chicken, but it was created in the 1960s by H.S. Hallock du Pont, and has not been recognized as a proper breed, perhaps because it does not, in fact, breed true. Yet.
Atlas of Living Australia in the spotlight, again
Commenting on a comment on my slightly disappointed take on a couple of new spatial datasets yesterday, our regular reader Glenn Hyman, another CGIAR CGI uber-geek, muses thus:
If I was a young GIS geek, I think I would concentrate on how to create online applications for the non-expert.
Do you mean, Glenn, the kind of “online application for the non-expert” which the Atlas of Living Australia aspires, with considerable success, to be? Which coincidentally is being so actively discussed on Twitter just now. 2 And which I need to road test again very soon, as there have been significant changes since the last time I took it around the block.

Eucarpia fishing in Malmo
The meeting of Eucarpia’s Genetic Resources Section is taking place in Malmo, Sweden this week, under the catchy title of “Pre-breeding — fishing in the gene pool.” Lots of old friends there. Maybe someone will tweet: there is a hashtag, but not much action yet.
LATER: No tweets yet, but here’s one presentation at least.
Playing around with new spatial datasets
Kai Sonder, CGIAR GIS geek extraordinaire, alerts us to the release of a couple of cool new global geospatial datasets, on roads and urban expansion. You need GIS software to get the full benefit of these, but at least for the city one some of the data 3 are available in KML format. This is what you get when you map in Google Earth Yerevan’s present extent together with the location of wheat germplasm accessions from Genesys.
Clearly some of those samples must have been collected a while back, when the city was perhaps smaller. And this is what you get when you map Armenia’s roads, again with wheat, but this time in DIVA-GIS.
A nice enough illustration of a bias towards collecting germplasm near roads that has been looked at in quite a lot of detail in another part of the world. But I just can’t help thinking these resources should be easier to play around with. Especially together.
LATER: Spurred on by Cedric and Jeremy, let me spell it out in more detail. What I would have liked is for both datasets to be available in their entirety in a format allowing easy upload to Google Earth. You will tell me that if you’re really, seriously interested in analyzing these datasets, together with others (like that Armenian wheat stuff from Genesys, say), you can do it by downloading the shapefiles, which is the standard format for such things, and opening them in any decent GIS software. And you’d be right. But isn’t there another kind of user? The one who wants to just, well, play around. Maybe even as a preliminary to more serious analysis, but initially just play around. That user is not well served by these resources. I know because I am that user, and I don’t feel well served.
