- Agricultural landscapes and biodiversity in China. Traditional farming practices good for biodiversity, modern bad. Therefore need intensification, to take pressure off natural habitats. But no, wait, that usually means monocultures and chemicals, which are bad. Oh crap. No mention of genebanks.
- Innovation in input supply systems in smallholder agroforestry: seed sources, supply chains and support systems. Decentralized commercial system probably best for getting quality agroforestry seed to smallholders. Unfortunately, nobody listening.
- Characterization of Italian lentil (Lens culinaris Medik.) germplasm by agronomic traits, biochemical and molecular markers. I object in principle to any paper that says a particular landrace is “the best.”
- The relationship between heterosis and genetic distances based on RAPD and AFLP markers in carrot. It is positive. Was this really not known before in carrots? What am I missing?
- Genetic diversity of taro (Colocasia esculenta (L.) Schott) in Vanuatu (Oceania): an appraisal of the distribution of allelic diversity (DAD) with SSR markers. 10 villages, 344 landraces, 324 distinct multilocus genotypes, genetic pattern reflects social networks. Situation in Andaman Islands not quite so interesting.
- A study of genetic diversity among Indian bread wheat (Triticum aestivum L.) cultivars released during last 100 years. More diversity after Green Revolution than before, but steadily decreasing.
- Ex situ conservation genetics: a review of molecular studies on the genetic consequences of captive breeding programmes for endangered animal species. Restricted access, and you know what? I couldn’t care less.
- Consequences of wooded shrine rituals on vegetation conservation in West Africa: a case study from the Bwaba cultural area (West Burkina Faso). I expect there are some, but with restricted access, what’s the point of even linking?
- Evaluating sweet potato as an intervention food to prevent Vitamin A deficiency. To have an effect, you’d have to replace all the other types with orange-fleshed ones. Well, almost. Wonder whether it will be presented at the “International Scientific Symposium on Food & Nutrition Security Information: From valid measurement to effective decision-making” early next year.
- Evaluation of variability of morphological traits of selected caraway (Carum carvi L.) genotypes. They’re actually breeding this stuff in Poland. But they had to get their germplasm from botanical gardens around Europe.
- Variation in baobab seedling morphology and its implications for selecting superior planting material. There is some.
- Edible Neotropical blueberries: antioxidant and compositional fingerprint analysis. The 5 species involved have different ones.
- Population genomics and speciation in yeasts. There’s a question as to whether yeast species in fact exist in any meaningful sense.
- Cereal–forage rotations effect on biochemical characteristics of topsoil and productivity of the crops in Mediterranean environment. Continuous cereal stressed the soil.
Europe calls for indicators shock
Regarding in situ and on-farm conservation, the EU requested the identification of indicators of diversity to establish and monitor changes in diversity at a national, regional and global level.
That’s from IISD’s report on day 2 of CGRFA 13. ((Do pay attention: that’s the FAO Commission on Genetic Resources for Food and Agriculture.)) I like to think it’s because they read our post.
Genetic erosion gets worse
We get hours of amusement from poking holes in the many ways in which statements about the loss of 75% of agricultural biodiversity are likely to be less than accurate any way you slice them. But here’s an entirely new wrinkle. A friend recently wrote asking for some moral support for a grant proposal, which included a forceful justificatory phrase to the effect that 75% of agricultural diversity has been lost since 1990. ((My emphasis, as the posh editors say.))
I twitted him gently about this, something snitty to the effect of “interesting statistic, have you got a source for that?” And blow me down if he didn’t. Not just any old source either. A communication from the [European] Commission to the European Parliament, the Council, the Economic and Social Committee and the Committee of the Regions, no less, entitled Our life insurance, our natural capital: an EU biodiversity strategy to 2020, aka COM(2011) 244 final.
And there it is, on page 1 of the Introduction.
[A]ccording to the FAO … 75% of the genetic diversity of agricultural crops has been lost worldwide since 1990.
I wonder where they got that figure? Not from FAO. The same year is present in at least one other language, so if it is a typo it entered the proceedings early. But honestly, did nobody find it just the least little bit odd? Then again, my friend didn’t either. I suppose we’re the odd ones.
Brainfood: Tomato erosion, Cassava starch, Landscape diversity, American chestnut, Niche models, Dormancy genes, Herbarium collections, Indian livestock breeding, Banana breeding, Pollinators, Shattering gene, Participatory research
- The risks of success in quality vegetable markets: Possible genetic erosion in Marmande tomatoes (Solanum lycopersicum L.) and consumer dissatisfaction. Market takes the fun out of landraces.
- Genetic variability of root peel thickness and its influence in extractable starch from cassava (Manihot esculenta Crantz) roots. Starch content depends on dry matter content and peel thickness. About 1500 accessions from CIAT evaluated for the latter, so lots to play around with.
- A meta-analysis of crop pest and natural enemy response to landscape complexity. More landscape complexity means more natural enemies. Still no cure for cancer.
- American Chestnut past and future: Implications of restoration for resource pulses and consumer populations of eastern U.S. forests. Reintroduction of blight-resistant chestnut may have some weird effects on other species.
- Keep collecting: accurate species distribution modelling requires more collections than previously thought. Oh damn.
- Variation in seed dormancy quantitative trait loci in Arabidopsis thaliana originating from one site. Is due to two QTLs. Also flowering time. But no, I don’t understand that “In contrast…” at the end of the abstract either.
- Tracking origins of invasive herbivores through herbaria and archival DNA: the case of the horse-chestnut leaf miner. Another use for old herbarium specimens: finding evidence of pests.
- Animal breeding in India – a time for reflection, and action. The reflection is that genetic improvement has stagnated, so the action needed includes better phenotypic record keeping, more attention to local diversity and community-breeding programmes.
- Performance of micropropagation-induced off-type of East African highland banana (Musa AAA – East Africa). A promising avenue for improvement, the off-types yield more better bananas, a month later.
- Pollination services in the UK: How important are honeybees? Not as important as you might think!
- The same regulatory point mutation changed seed-dispersal structures in evolution and domestication. Cabbage-family fruit development and rice shattering share the same single point mutation.
- Participatory research and on-farm management of agricultural biodiversity in Europe. By Michel “Pimpert”. That should be Pimbert. Old news, but worth mentioning.
A call for information on threatened Italian vineyards
I suppose there’s some poetic meaning to the coincidence that it is while I’m travelling in the oldest wine-producing region of the world that I notice on Facebook a call from Slow Food Italia for information on vineyards threatened with destruction. Be that as it may, it will be interesting to see what response Slow Food get, and what use they make of it. We have blogged here on various occasions about the desirability of an early warning system for genetic erosion, and how one might go about setting one up. This might have the makings of one, at least for grapevine in Italy.
