- Informal “Seed” Systems and the Management of Gene Flow in Traditional Agroecosystems: The Case of Cassava in Cauca, Colombia. Farmers move cassava around a lot.
- Ecological and socio-cultural factors influencing in situ conservation of crop diversity by traditional Andean households in Peru. Farmers should be supported in moving tubers around more.
- Nutritional and morphological diversity of breadfruit (Artocarpus, Moraceae): Identification of elite cultivars for food security. There’s a lot of it.
- Man the Fat Hunter: The Demise of Homo erectus and the Emergence of a New Hominin Lineage in the Middle Pleistocene (ca. 400 kyr) Levant. Disappearance of elephant led to replacement of Homo erectus. Quite a difference from the more recent hominin-elephant dynamic.
- Fitness consequences of plants growing with siblings: reconciling kin selection, niche partitioning and competitive ability. All agriculture is about reconciling kin selection.
- Cultivation and domestication had multiple origins: arguments against the core area hypothesis for the origins of agriculture in the Near East. Revisionism rules.
- Tracing genetic differentiation of Chinese Mongolian sheep using microsatellites. Five populations clustered by fancy science into, ahem, five populations.
- Road connectivity, population, and crop production in Sub-Saharan Africa. Fancy science reveals better roads would be good for agriculture. Hell, my mother-in-law could have told them that.
- Econutrition: Preventing Malnutrition with Agrodiversity Interventions. Home gardening is the way to go.
- Carotenoid and retinol composition of South Asian foods commonly consumed in the UK. Palak paneer is not just good, it’s good for you.
Nibbles: Law book, Sheep breeding, Pig breeding, Pink mushrooms, Coconut genome, Cassava genome, Apples in the Big Apple, Street food, Irish corner, Peach palm tissue culture, Seed saving, Kenyan farmers, First farmers, Tenure, Peppermint facts, Mountains, Taro network, Shea
- Juliana Santilli guest-blogs on the book Agrobiodiversity and the Law over at Agrobiodiversity Grapevine.
- ICARDA tells communities how to set up a sheep breeding programme.
- While an Indian institute breeds pigs, with Canadian help.
- Another Indian institute does the same for mushrooms, with no help.
- And yet another sequences the coconut genome.
- While BGI sequences a whole bunch of CIAT cassava stuff. Only yesterday they were doing rice. Yeah, but only 50, and you gotta keep those sequencers going, don’t you? Would be nice to know how much the CGIAR is paying BGI annually. Do they get frequent flyer miles? Have they negotiated a corporate rate?
- A Kazakhstan apple tree grows on the East River. A forest, actually. If it had been in England, it might eventually feature here. Ok, ok, our quest for connections is occasionally overdone. Made you look, though.
- Ah, kimchi! Ah, fish empanadas! So much interesting food, only one stomach lining…
- Danny tells us about Ireland’s CWR database. In other news, Ireland has CWR. Oh, and then he goes crazy on the Biodiversity for Nutrition mailing list. Did he get his goat is what I want to know.
- AoB on in vitro peach palms. Why read the paper, when AoB abstracts the abstract?
- Bifurcated Carrots on seed saving in Canada. Video goodness galore.
- And while we’re talking cinema, here’s news of a movie on a year in the life of four Kenyan farmers.
- From Kenyan farmers to First Farmers. The Womb of Nations. I like that. And more. Agricultural hearths. I like that too.
- Four days of discussion about land tenure. May not be enough, actually.
- “…70 per cent of the peppermint sold in the US is descended from a mutant in a neutron-irradiated source.” Good to know.
- I missed International Mountains Day. Again.
- That EU-funded taro mega-project from a PNG perspective.
- What I like about this Worldwatch series on neglected plants is that they’re not factsheets. Yet.
Brainfood: Growth, Grasslands, Seaweed, Apple pedigrees, Marker assisted selection, Ants, Iron biofortification
- Economic growth and biodiversity. “There is no fundamental conflict between economic growth and biodiversity.” Hmmmmn.
- Phytodiversity of temperate permanent grasslands: ecosystem services for agriculture and livestock management for diversity conservation. At heart, a plea for more interdisciplinary research.
- The Interaction between Seaweed Farming as an Alternative Occupation and Fisher Numbers in the Central Philippines. Alternative occupations don’t necessarily reduce over-harvesting.
- Genotyping of pedigreed apple breeding material with a genome-covering set of SSRs: trueness-to-type of cultivars and their parentages. Your papa aint your papa but your papa don’t know.
- The GCP molecular marker toolkit, an instrument for use in breeding food security crops. Marker-assisted selection is not yet used for Musa spp., coconut, lentils, millets, pigeonpea, sweet potato, and yam. For the other 12 crops, 214 molecular markers were found to be effectively used in association with 74 different traits.
- Ant diversity and bio-indicators in land management of lac insect agroecosystem in Southwestern China. When you’re managing for a wild insect, the wild species are secondary.
- Biofortification for combating ‘hidden hunger’ for iron. Swings and roundabouts apply, with a vengeance.
Brainfood: OSP adoption, Milk quality, Passport data quality, Historical collections, Sweet potato domestication, African veggies, Baobab diversity and domestication, Cassava diversity, Strawberry breeding, Barley GWA, Pest symbionts, Maize diversity and climate change
- A large-scale intervention to introduce orange sweet potato in rural Mozambique increases vitamin A intakes among children and women. Just 1 year of training worked just as well as a higher intensity intervention (3 years) in increasing OSP and vitamin A intake by younger children, older children and women, and decreasing prevalence of inadequate vitamin A intakes. OSP represented about half of all sweet potatoes consumed so I guess there was not complete replacement of local varieties.
- Composition of milk from minor dairy animals and buffalo breeds: a biodiversity perspective. There are significant interbreed and inter-species differences. Dromedary milk is closest to cow milk, mare and donkey milk maybe the healthiest, but moose milk is the one I’d like to try.
- Quality indicators for passport data in ex situ genebanks. That would be the genebanks in Eurisco. Verdict: not bad, but could do better. Most variation in quality is among institutes.
- Exploring the population genetics of genebank and historical landrace varieties. Old samples of dead seeds of 4 crops in Swedish museum jars more genetically variable than genebank accessions, but it’s not the genebank’s fault. And at least their seeds are still alive. Also no genetic correspondence between geographically matched museum and genebank samples.
- Combining chloroplast and nuclear microsatellites to investigate origin and dispersal of New World sweet potato landraces. Two areas of domestication, probably from a single wild progenitor species: lowland NW South America and lowland Central America/Caribbean. Genetic differences between these 2 genepools not accompanied by morphological differences, but then again nobody’s looked properly, and the current descriptors are useless anyway.
- The significance of African vegetables in ensuring food security for South Africa’s rural poor. Their huge potential is being thwarted by evil extensionists. Ok, but don’t we need to move beyond that?
- Comparative study on baobab fruit morphological variation between western and south-eastern Africa: opportunities for domestication. Hang on a minute, aren’t there a million factsheets about all this?
- Marriage exchanges, seed exchanges, and the dynamics of manioc diversity. Kinship structures determine cassava diversity patterns in Gabon. Matrilineal societies have more diversity.
- Interspecific hybridization of diploids and octoploids in strawberry. You get pentaploid and tetraploid plants.
- Genome wide association analyses for drought tolerance related traits in barley (Hordeum vulgare L.). Ok, deep breath. Over 200 accessions, both wild and cultivated, from 30 countries, so quite variable, but also structured. There were some QTLs that differed between dry and wet sites, but they didn’t explain much phenotypic variation, and they couldn’t be related to previous work. So GWA not much use, probably because of population structure. But couldn’t that have been predicted? And isn’t it possible to do something about structure in the analysis?
- Population genetics of beneficial heritable symbionts. Of insects, that is. Mostly proteobacteria. So my question is, could somehow attacking the symbionts form the basis of a pest management strategy?
- Projecting the effects of climate change on the distribution of maize races and their wild relatives in Mexico. Many races and wild relatives are predicted to shift in geographic distribution. Unless of course agronomy intervenes. Teocinte taxa should be collected.
Nibbles: Q&A, Zoopharmacognosy, Pigeonpea genome, Turkey, Wheat relatives
- Everyday agriculture mysteries solved.
- Other animals self-medicate too.
- Dueling pigeonpea genome sequencers? Who knew. Well spotted, James.
- I’m thankful for turkeys.
- And for the crop wild relatives in ICARDA’s genebank too.
