- Cool infographics on food, trade and, well, a particular sort of trade. And how to make your own.
- Soil would be a cool place to start.
- The bananas of your grandchildren and the carrots of your grandparents. Plus a funny peculiar idea about how to keep seed of such stuff for 50 years.
- Which you don’t need to do anyway because “[r]eplacing traditional seeds with commercial varieties is not an official government policy,” at least in South Africa. Unlike in the EU, I guess. Oooooh, did I just say that? Such a naughty muppet.
- Ok, let me make up for that with some thoughts on breeding for the sorts of places where those traditional seeds might be found, in Africa and in Europe.
- Of course, in such places, you have to know your aphids. Before they go and eat a bacteria and change their DNA. Tricky to breed for resistance to that, I would guess.
- Oh, but here are also the views of someone in Europe who would rather not have anything to do with traditional seeds and their accompanying aphids at all. Why can’t we just get along?
- Why, for example, can we all not get to love mboga za watu wa Pwani. You heard me. And no, residing far from the Swahili Coast is no excuse. Jeremy unavailable for comment.
- He did, however, point out that “[t]he value of male prostitutes exceeds that of farmlands.” Yep, Robigalia time again.
- Meanwhile, not far from the Swahili Coast, some people are thinking that man does not live by mboga alone… No, he must have nyama too.
- And speaking of which: giving sausages a name. On this, I am with Bismarck. No such porky nonsense from the French.
- “Nine thousand years of Mexican agriculture” online. And five hundred on the stove.
- Pollinating date palms just got a whole lot easier. And no, this doesn’t have anything to do with any of the other nibbles, but I thought it was cool.
Brainfood: Lupin restoration, Balkan wheat drought tolerance, Metabarcoding, Wild sheep genetics, Organic vegetables, Diversity protects, Sorghum geneflow, Wild sunflower genetics
- A Molecular and Fitness Evaluation of Commercially Available versus Locally Collected Blue Lupine Lupinus perennis L. Seeds for Use in Ecosystem Restoration Efforts. Commercial seed sources can be dodgy, and that’s a problem.
- Comparison of responses to drought stress of 100 wheat accessions and landraces to identify opportunities for improving wheat drought resistance. 20 Balkan landraces seemed to be more drought tolerant than 80 accessions sourced globally.
- Towards next-generation biodiversity assessment using DNA metabarcoding. You gotta be kidding me, metabarcoding? Will they be applying it to soils? Yep.
- Selection and microevolution of coat pattern are cryptic in a wild population of sheep. You need to look at the genes.
- Will they buy it? The potential for marketing organic vegetables in the food vending sector to strengthen vegetable safety: A choice experiment study in three West African cities. Not enough.
- Plant diversity improves protection against soil-borne pathogens by fostering antagonistic bacterial communities. Chalk another one up to diversity. Did they say soil?
- Local scale patterns of gene flow and genetic diversity in a crop–wild–weedy complex of sorghum (Sorghum bicolor (L.) Moench) under traditional agricultural field conditions in Kenya. Mostly crop-to-wild, which could be a problem if transgenics are ever grown. If.
- Adaptation with gene flow across the landscape in a dune sunflower… is leading to “ecological” speciation.
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.
Brainfood: Bison on the prairie, Tilapia breeding, AM on banana, Phenomics,Yam collection, Nopales, Arable flora
- Can bison play a role in conserving habitat for endangered sandhills species in Canada? Maybe, hence the recommendation to re-introduce them. Incidentally, there are a few crop wild relatives on the list of threatened plants of Canada.
- Genetic improvement of farmed tilapias: Genetic parameters for body weight at harvest in Nile tilapia (Oreochromis niloticus) during five generations of testing in multiple environments. The 10-year “Genetic Improvement of Farmed Tilapias” (GIFT) project was not a complete waste of time. The GIFT population will respond well to selection for increased body mass, and you dont have to do the evaluation in lots of different environments.
- Mycorrhizal colonization of major banana genotypes in six East African environments. Different banana genotypes had different levels of infection, but environment also plays an important role. Important because arbuscular mycorrhizal fungi may increase production.
- On the use of depth camera for 3D phenotyping of entire plants. An example of this.
- Genetic and phenotypic diversity in a germplasm working collection of cultivated tropical yams (Dioscorea spp.). Should be a good starting point for improvement programmes. Kind of like the GIFT population, then, eh? But starting point? Haven’t people been breeding yams for a while?
- Cytogeography of the Humifusa clade of Opuntia s.s. Mill. 1754 (Cactaceae, Opuntioideae, Opuntieae): correlations with pleistocene refugia and morphological traits in a polyploid complex. The southeastern and southwestern U.S. represent glacial refugia for diploid members of the clade, and a whole bunch of polyploids resulted when the taxa spread out again after glacial episodes. How many of these are eaten is what I’d like to know, and whether ploidy affects that. I suppose climate change will lead to further complications?
- The impact of agricultural intensification and land-use change on the European arable flora. Is significant. Not least because some crop wild relatives are involved, although that’s not really discussed here.
Nibbles: Forests and agriculture, Seed collecting, Banana book, Fermentation, Cucumber history, Myrrh, Farm systems, Dog genetics, Chocolate wars
- Seven forest myths exposed. And more on the work debunking one of them. Yeah I know we already Nibbled it, get over it.
- And you know what, here’s another one we already Nibbled, on collecting seeds in Central Asia. But I just read it again in the hardcopy version and it’s really cool and I like seeing people I know in funny shorts. Incidentally, the dead tree version has a link to Vaviblog that is unaccountably missing online.
- Will no one buy me this fabulous banana book? (Not if you keep being rude to your reader. Ed.)
- Second installment of that we-farm-because-we-like-beer thing. I’m not sure about the theory, but I like the way this guy writes. Yes, it’s a little look at me, look at me. But sometimes you need that.
- Tales of the cucumber. Does anyone remember if we blogged about this paper?
- More to myrrh than meets the eye. And more than most folk need to know.
- Oxford boffins say a pox on both your houses: “environmentally friendly” farms better than conventional and organic.
- National Geographic tackles the dog. Amazingly, all the photos are of, ahem, dogs.
- What’s with all this stuff about cacao lately? Has someone sequenced another variety or something?
