- Cambridge University summarizes the 10,000-year journey “from foraging to farming”.
- A journey that’s still taking place at the Kuk Early Agricultural World Heritage Site in Papua New Guinea.
- Where researchers are working with farmers to see which vegetables grow best where.
- Tonka beans (Dipteryx odorata) are the foundation of a conservation programme in Venezuela.

Brainfood: Dietary diversity, Diversity and diseases, Soil IK, Insect symbionts, Rhizobia, Wild lettuce, Tree genetic erosion, Pre-domestication barley, Strampelli
- Relating dietary diversity and food variety scores to vegetable production and socio-economic status of women in rural Tanzania. Dietary diversity was all too often alarmingly low, and when it was it was associated with seasonal fluctuations in the production and collecting of vegetables. But a more varied diet need not necessarily be healthier, so more procedural sophistication will be necessary in follow-up studies.
- A risk-minimizing argument for traditional crop varietal diversity use to reduce pest and disease damage in agricultural ecosystems of Uganda. For Musa and beans, more varietal diversity meant less damage and less variation in damage.
- Exploring farmers’ local knowledge and perceptions of soil fertility and management in the Ashanti Region of Ghana. Soils which farmers described as being more fertile were, ahem, more fertile.
- Population genetics of beneficial heritable symbionts. Of insects, that is. Important because they can confer protection from natural enemies, among other things. They behave a bit, but not entirely, like beneficial nuclear mutations.
- Widespread fitness alignment in the legume–rhizobium symbiosis. There are no cheaters.
- Genetic polymorphism in Lactuca aculeata populations and occurrence of natural putative hybrids between L. aculeata and L. serriola. Not much diversity in Israel, surprisingly. But isozymes?
- Meta-Analysis of Susceptibility of Woody Plants to Loss of Genetic Diversity through Habitat Fragmentation. The standard story — that trees suffer less genetic erosion because they are long-lived — is apparently wrong, even for wind pollinated trees.
- Large-scale cereal processing before domestication during the tenth millennium cal BC in northern Syria. “This was a community dedicated to the systematic production of food from wild cereals.”
- Nazareno Strampelli, the ‘Prophet’ of the green revolution. Before Norman, there was Nazareno.
- The memory remains: application of historical DNA for scaling biodiversity loss. Historical collections of salmon scales reveal many connections between modern evolutionary significant units (ESUs) in the Columbia River and old ones; but also, intriguingly, some differences.
Nibbles: Ancient sauce, Easter eggs, REDD and biodiversity
- Ancient fish sauce recreated.
- Easter egg symbolism deconstructed.
- Monitoring biodiversity in REDD projects. Including CWR?
Nibbles: Treaty in Malaysia, Vavilov in Sardinia, Vegetative crops, Aquaculture, Indian AnGR, Seed Savers, Ancient Egypt and thereabouts, Quinoa in Chile
- Michael Halewood in Genebank Policy Hell.
- Vavilov in Genebank Database Hell.
- A guide through Clonal Crops Conservation Hell.
- Pakistan contemplates genebank for carp “pure line and improved stairs for SAARC countries.” Bicycles next, I suppose. But will Ghana follow suit?
- Meanwhile across the border, India is putting resources into livestock conservation at both national and state level.
- Italian broccoli variety moves to Florida and makes the big time.
- And ancient Egyptian gardens make the big time in Amsterdam. Too bad it wont be possible to exchange seeds.
- I bet those ancient Egyptians had taro. They certainly had wheat and barley.
- But not quinoa, alas, despite what Thor Heyerdahl might have thought.
Brainfood: Beans, Potatoes, Lettuce, Agave, Gaming, Mangroves, Ancient millets, Ancient missions
- Mesoamerican origin of the common bean (Phaseolus vulgaris L.) is revealed by sequence data. Revealed is kinda strong isn’t it? This from a bean expert of my acquaintance: “Yes, we knew that, as it seems to be the case of all species of the Phaseoli section. They could have done a bit better in including the 2 populations of Cordoba mountain, in order to see whether these belong to the first migration to the Andes, or the second one. Wild vulgaris from western Panama, or Venezuela, could have helped in this regard too. We have shown years ago that the complex genetic structure in Mexico and in Colombia is the result of these floristic migrations combined with gene flow events because beans cross among themselves.”
- The Enigma of Solanum maglia in the Origin of the Chilean Cultivated Potato, Solanum tuberosum Chilotanum Group. These are long-day adapted and therefore crucial to the history of the potato in Europe. But the various sorts of evidence looked at to investigate their relationship to the rare Chilean wild relative S. maglia just do not agree. Bummer.
- Wild and weedy Lactuca species, their distribution, ecogeography and ecobiology in USA and Canada. So Iowa is a wild lettuce hotspot. If you’re interested in the germplasm, it’ll be in the genebank of Palacký University in the Czech Republic.
- Sustainability of the traditional management of Agave genetic resources in the elaboration of mezcal and tequila spirits in western Mexico. Tequila industrial agriculture should learn from the traditional kind.
- Fate of the World: computer gaming for conservation. Worth a try. No, really.
- The Economic Value of Mangroves: A Meta-Analysis. You might think there would be a value in the abstract; you would be wrong.
- Early millet use in northern China. That would be Setaria italica and Panicum miliaceum, and new evidence from ancient starch grain on pottery and grinding stones found in archaeological sites has pushed back their cultivation in N China by 1000 and 2000 years respectively, to about 9500-7500 BC. The Archaeobotanist has more, as ever.
- Digitization and online availability of original collecting mission data to improve data quality and enhance the conservation and use of plant genetic resources. They’re there (and here; what’s up with that?) to consult and make use of if you want.
