The 2010 Biodiversity Indicators Partnership has relaunched its website. Not earthshattering news, I agree, but a good opportunity to remind ourselves that, perhaps surprisingly, the list of indicators includes one on ex situ crop collections and another on genetic diversity of terrestrial domestic animals. There’s also an indicator tracking the contribution of biodiversity to nutrition, and another looking at the area of sustainably managed agricultural ecosystems. All in all, not bad for agrobiodiversity. Must have taken a lot of lobbying, though.
Using photos to share knowledge about agrobiodiversity
ResourceShelf reported on a Library of Congress blog post on the photographs in the US Farm Security Administration and Office of War Information collection, the most popular among which are now available in a Flickr group under the heading FSA/OWI Favorites. That led me to some wonderful colour photos from the 30s and 40s from the same source. One of them particularly caught my eye. Not because it’s particularly well framed or for its dramatic subject matter. It’s just a pretty standard shot of some harvested oats fields in southeastern Georgia taken in May 1939. But someone — a Mr Raymond Crippen, actually, who sounds as if he has first-hand experience of wartime Georgian oat fields — has taken the trouble to annotate different parts of the image:
The most common grains in shocks were wheat, oats, barley. Farmers hated working with the barley. The “beards” stuck to sweaty arms, found their way down shirts – and they caused great itching.
This strikes me as a great way of documenting and sharing indigenous knowledge of agricultural practices and biodiversity. Has it ever been tried in a more formal way?
Coffee wild relative voted among top 10 new species
Here’s a cool idea. Apparently the International Institute for Species Exploration at Arizona State University and an international committee of taxonomists get together regularly and pick the top 10 new species described in the previous year. They’ve just announced the 2008 picks, and they include a crop wild relative. It’s Coffea charrieriana, a caffeine-free coffee from Cameroon. It was named after “Professor A. Charrier, who managed coffee breeding research and collecting missions at IRD during the last 30 years of the 20th century.” And with whom I had the privilege to work some years back in the early days of the African Coffee Research Network. Congratulations to all concerned.
Sardonic grin greets paper on sardonic grin
Damn you, agrobiodiversity. Every day something new. For example, did you know that a plant is behind the phrase “sardonic grin”? Well, apparently, the roots of the word “sardonic” go back to Homer, who adapted the ancient word for the Sardinians “because of the belief that the Punic people who settled Sardinia gave condemned men a potion that made them smile before dying”? That’s from an ANSA press release which goes on to describe some recent research which purports to nail down the active ingredient of the potion.
It turns out to be polyacetylenes from Oenanthe fistulosa, an umbel. They “cause facial muscles to contract and produce a grimace or rictus.” This species is not cultivated, I don’t think, but a congeneric is: O. javanica is used as a vegetable in parts of Asia. So O. fistulosa is a crop wild relative, sort of. Anyway, the ANSA release doesn’t give details of the paper, but I believe it might be a February article in Journal of Natural Products by a group of Italian and Polish researchers.
One of the authors, Mauro Ballero from the botany department of the Universita di Cagliari, which is in Sardinia, had this to say about the significance of the research, no doubt with a sardonic grin on his face:
The good news is that the molecule in this plant may be retooled by pharmaceutical companies to have the opposite effect.
Down with the invader!
Happy International Day for Biological Diversity! This year’s theme: invasives.
Invasive alien species exacerbate poverty and threaten development through their impact on agriculture, forestry, fisheries and natural systems, which are an important basis of peoples’ livelihoods in developing countries. This damage is aggravated by climate change, pollution, habitat loss and human-induced disturbance.
Next year we’ll do something special on this day, we promise…
