- Genetic diversity and relationships among Italian and foreign almond germplasm as revealed by microsatellite markers. I hate it when abstracts of paywalled papers don’t really tell you anything of any use.

Need to focus conservation on Dawro, Sheka, Gamgofa and Keffa and across altitudes. I can’t believe we didn’t already know that but, unlike with the Italian almonds, at least this bit of potentially useful information is in the abstract. And the paper is free.

- Consumers as Conservers—Could Consumers’ Interest in a Specialty Product Help to Preserve Endangered Finncattle? Yes, if the consumers are green male carnivores. But then I could probably have told you that.
- What Influences Farmers’ Choice of Indigenous Adaptation Strategies for Agrobiodiversity Loss in Northern Ghana? Well, if I read this right, it is whether they have a radio, off-farm income and access to extension. But the math is complicated.
- Does agricultural crop diversity enhance soil microbial biomass and organic matter dynamics? A meta-analysis. They mean rotations, and the answer is yes.
- Evaluation of selected sweetpotato (Ipomoea batatas) accessions for drought tolerance. Gotta love it when a genebank gets some use and a student gets a degree.

Stop vitamin A supplements
The editorial by Thorne-Lyman and Fawzi in 2011, (1) referring to the meta-analysis of the impact of vitamin A supplements by Mayo-Wilson, Imdad and others, (2,3) has now become more important than ever. The DEVTA results, only informally available in 2011, have now been published, (4) with extensive implications; indeed, as the editorial (1) says: ‘… the null findings have left lingering questions. Is vitamin A supplementation effective?’. These results have been the subject of conflicting comments recently in the Lancet, e.g. (5,6). But a number of inferences that should be drawn from the compilation and analysis of the evidence from trials prior to DEVTA (2,3) help answer this lingering question, and have not received adequate attention. There are three key related points, which now point to the need to seriously consider concrete steps to move beyond 6-monthly vitamin A supplementation at unphysiological levels.
OK, there’s a lot in that introduction to a recent paper in the British Medical Journal to digest, but it is worth it. I know I bang on about the colossal boondoggle that is high-dose vitamin A supplementation, but there’s a reason. It seems to be a complete waste of money based on a very limited reading of the evidence. In 2011 the BMJ published an editorial on Improving child survival through vitamin A supplementation (which is behind a paywall) that referenced a meta-analysis of supplementation. The new paper — Is vitamin A supplementation effective? — brings things up to date with a more detailed analysis of some of the research only hinted at in the original articles. Bottom line: there is no evidence for large-scale effectiveness of vitamin A supplements on child mortality.
As the authors of the rebuttal ask, why are resources still going into supplementation campaigns of the old sort? And they conclude:
Improved diets, fortified foods, and multiple micronutrient provision would surely bring broader improvements in nutrition to more people, including reproductive aged women who are now largely excluded.

- Evaluation of Genetic Diversity of Sichuan Common Wheat Landraces in China by SSR Markers. “Our results suggested that Sichuan common wheat landraces is a useful genetic resource for genetic research and wheat improvement.” When is anything not?
- Identification and evaluation of sorghum (Sorghum bicolor (l.) moench) germplasm from Eastern Kenya. “These untapped resources could be useful in crop improvement programmes and in food security.” See what I mean?
- Genetic assessment of maize landraces from former Yugoslavia. No, wait, don’t tell me… “The results revealed a significant genetic heterogeneity indicating that the analyzed landraces could be valuable sources of genetic variability.” There you go.
- The Role of Home Gardens in Household Food Security in Eastern Cape: A Case Study of Three Villages in Nkonkobe Municipality. People who keep home gardens eat and sell the stuff they grow in their home gardens. And yet they need to be empowered. Oh, and naturally “[f]indings of this study will be useful to governmental and non-governmental bodies involved in promoting food security in the rural households.”
- A modelling study of the role of marine protected areas in metapopulation genetic connectivity in Delaware Bay oysters. Gotta site your seed populations for restoration with care.
- Conservation Genetic Resources for Effective Species Survival (ConGRESS): Bridging the divide between conservation research and practice. An online tool for making decisions about conservation, including based on genetic data, such as the kind above. May even be applicable to agricultural biodiversity.
- A prioritized crop wild relative inventory to help underpin global food security. Well here’s one decision making tool that certainly is applicable to agrobiodiversity.
- The impact of agricultural practices on soil biota: A regional study. It’s not good.
- Sustainable agriculture: possible trajectories from mutualistic symbiosis and plant neodomestication. Gotta make use of those arbuscular mycorrhiza. Wonder if these guys have read the paper above though.
- Rethinking Land Grab Ontology. “Responsible investments in land acquisition” or “responsibly destroying the world’s peasantry”? Not sure why nobody looks at the agricultural biodiversity implications of all this.
- Extension of energy crops on surplus agricultural lands: A potentially viable option in developing countries while fossil fuel reserves are diminishing. Something to do on all that surplus land being sold off?

A very special day
Today is Ada Lovelace Day, an annual celebration of women in science, technology, engineering and maths. It is also, I am reliably informed, Cake Decorating Day. No room, then, for sentimentality, but I must note that today is also the 7th anniversary of this website.
As we reported in 2006, Typhoon Xangsane had damaged the National Plant Genetic Resources Laboratory in the Philippines, but left IRRI’s genebank unscathed.
Seven years on, genebanks are still at risk, although there are also safety duplicates in the frozen wastes. And we’re still trying to keep up with agricultural biodiversity in all its many manifestations.
A few things have changed, too. Behind the scenes, we’ve had our ups and downs with our web host, who unilaterally terminated what we thought was a lifetime contract. And, as you might expect, we’ve both moved on in one sense or another from where we were back in 2006.
Let me, though, ask one favour of you, dear reader: is there anything you either like or dislike, that you would like to see more or less of? Leave a comment. We can’t promise, but we can try.
And thanks for reading.
