- The impact of distance and a shifting temperature gradient on genetic connectivity across a heterogeneous landscape. Climate change bringing formerly genetically isolated populations together, possibly increasing adaptive potential.
- Intra-varietal genetic diversity of the grapevine (Vitis vinifera L.) cultivar ‘Nero d’Avola’ as revealed by microsatellite markers. 15 distinct genetic group among 118 plants from 30 Sicilian vineyards seems quite a lot.
- Emerging cultivation of oregano in Sicily: Sensory evaluation of plants and chemical composition of essential oils. More from Sicily. Wild is best.
- Effect of vineyard-scale climate variability on Pinot noir phenolic composition. Its complicated. But at least Pinot noir is not like Nero d’Avola. Or is it? Oh, crap.
- Landraces in Inland areas of the Basilicata region, Italy: monitoring and perspectives for on farm conservation. “Farmer-maintainers” of landraces tend to be old and isolated. Interesting stratified sampling strategy. Basilicata? They grow horseradish there, don’t they? They do indeed.
- Critical distances: Comparing measures of spatial accessibility in the riverine landscapes of Peruvian Amazonia. GIS-calculated time-based accessibility influences rural livelihoods and land use pressure. And agrobiodiversity? Apply to Basilicata next?
- A morphological assessment system for ‘show quality’ bovine livestock based on image analysis. Image of side of animal fed through neural network almost as good as experts in determining how beautiful the animal is. well there’s a triumph for science.
- Endosymbionts and honey bee colony losses? Something else to add to the list of possible causes of colony collapse disorder.
- Commercial teas highlight plant DNA barcode identification successes and obstacles. About a third of products revealed signatures of stuff that was not listed in the ingredients, but that could be due to a number of reasons.
- What would happen to barley production in Finland if global warming exceeded 4°C? A model-based assessment. Nothing good, surprisingly. Better get some new varieties, I guess.
- Cajanus platycarpus (Benth.) Maesen as the donor of new pigeonpea cytoplasmic male sterile (CMS) system. Gotta love those CWRs.
- Australia’s Stock Route Network: 1. A review of its values and implications for future management. Established for movement of livestock before trucks and trains, but has lots of endangered species and communities. Great value on many fronts, in fact. Needs proper governance though.
- Should forest restoration with natural hybrids be allowed? Yep.
Nibbles: Heat, Watermelons, Rye, Apples, Solanum melongena, Pinus edulis, Food systems, Indian rice, Glycene
- Heat takes growing toll on Kansas farm crops. Heat, not drought. Just sayin’.
- Amateur Hour I: watermelons.
- Amateur Hour II: perennial rye.
- Amateur Hour III: red-fleshed apples.
- Bronjenas. An eggplant by any other name is still an aubergine (Solanum melongena).
- Not your average pinoli.
- We need to fix the food system. But how? Answers on a postcard, please.
- Saving traditional rice landraces in India. Of which there are maybe 3,000 in the NE alone. No mention of genebanks.
- Superstar Swedish soybeans
Brainfood: Chinese landscapes, Agroforestry seed, Italian lentils, Carrot heterosis, Taro in islands, Indian wheat, AnGR ex situ, Woodland shrines, Vitamin A, Caraway, Adansonia, Neotropical blueberries, Yeast genetics, Rotations
- 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.
