Does this avalanche of news articles about frankincense happen every year around Christmas?
Nibbles: Pre-Columbian ecology, Huitlacoche, Nutrition, COP17, Walnuts, Custodians, Price Volatility, Kenyan farmers, Education, Peach pests, Unhappy Talk
- Special Journal issue on Environmental changes and pre-Columbian human influence in the Amazon region.
- Porn on the cob. A smut story with a headline so good, I’m sure to steal it.
- A practical field manual cum guide to Improving nutrition with agricultural biodiversity.
- Ag researchers “speak with a single voice” to “call on climate negotiators to endorse a work programme for agriculture”. We shall see.
- And will it come in time to Save the Walnut?
- New book on “Custodians of Biodiversity“.
- Brussels Briefing on Food Price Volatility. Today! Soon!
- China hears how Kenyan farmers can benefit from traditional vegetables.
- “Are plants like us?” It depends …
- A minor increase in biodiversity protects peaches from nematode pests.
- Climate change in the Pacific: The problem, according to the Aussies. The solution, according to the ADB.
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: Taiwan seedbank, American agroforestry
- Taiwan should establish a national seed bank. It says here. But will it be a genebank?
- Agroforestry in the USA and in the ancient Maya lands.
Nibbles: Heirloom cattle, Saleb, Wheat protein, Dog domestication, Rooibos
- Why Highland Cattle? Because they look so cool, of course.
- It’s sahlib time!
- Australians find the extra gluten protein gene they need in Italian wheat.
- Where the hell was the dog domesticated?
- Rooibos tea is latest climate change victim.
