Kew and IUCN made a splash today with the Sampled Red List Index for Plants. A representative sample of 7,000 species of plants was selected from the comprehensive IUCN Red List Index for detailed monitoring. 1 You can contribute to the Sampled Red List in a wiki-like environment, and follow its progress on the inevitable blog. An interactive map allows some basic exploration of the data. The headline number is that 25% of plant species are threatened. There are various crop wild relatives among the 7,000 species, 2 so it might be possible to calculate some statistics for that particular category, to complement other efforts.

The geography of black rice
Sometimes it pays to spend some time in Genebank Database Hell, if you can fight through the pain.
You may remember a piece recently about the antioxidant properties of black rice. But where does black rice come from? Well, hanging around with the Genesys and GRIN-Global crowd in the past couple of days has allowed me to come up with this map in answer to that deceptively simple question.
In yellow are all the rice accessions from Asia which have coordinates, as recorded in the IRRI database, EURISCO and GRIN. In red are the black rice accessions.
You’d have thought such a map would be pretty easy to make. But you’d be wrong. I had to get an Excel spreadsheet from IRRI with the characterization data, 3 and mash it up with the passport data in Genesys for the same accessions, and then export two separate kmz files and fiddle around in Google Earth. 4 Well, they don’t call it Genebank Database Hell for nothing. But it is getting better, slowly but surely.
Pavlovsk interpretation depends on the kindness of strangers
Can you help provide a precis of this broadcast, “Results of evaluation conducted by the expert commission regarding the state of lands belonging to the Pavlovsk Experiment Station.”
And thanks to commenter Mike H for the link to the VIR site.
Scientist of bees gets genius grant
Latest MacArthur Fellows include: 5
Marla Spivak … an entomologist who is developing practical applications to protect honey bee populations from decimation by disease while making fundamental contributions to our understanding of bee biology.
A pedant speaks: Let’s hope she can also tackle some of the diseases that do more than decimate.
