- Species vulnerability to climate change: impacts on spatial conservation priorities and species representation. Yes, you can focus on sensitive species, but it comes at the cost of representativeness.
- Estimating management costs of protected areas: A novel approach from the Eastern Arc Mountains, Tanzania. Those are $ costs per pixel on the map, which I’ve never seen before. Don’t think they took into account the effects of climate change, though. Maybe they should get in touch with the Aussies above?
- The use of mycorrhizal inoculation in the domestication of Ziziphus mauritiana and Tamarindus indica in Mali (West Africa). It would help.
- A new integrative indicator to assess crop genetic diversity. Includes varietal richness, spatial evenness, between-variety genetic diversity, and within-variety genetic diversity. Not much left, really. Anyway, remember this from last week? Anyone out there going to put 2 and 2 together?
- Assessing Nutritional Diversity of Cropping Systems in African Villages. A new tool! Different from the integrative indicator above! Anyone going to put 4 and 2 together?
- Agriculture-Nutrition Pathways Recognising the Obstacles. “The pathways between agriculture and nutrition seem to be laden with impediments, particularly in the form of intricate household preferences.” Those pesky preferences.
- The chestnut blight fungus world tour: successive introduction events from diverse origins in an invasive plant fungal pathogen. Asia to N. America to Europe, but more than once. All very complicated. The surprising thing is that low diversity and low admixture have nevertheless still resulted in success in disparate places. What fiendish molecular or biochemical mechanism is behind this? Only more research will show, natch.
- Translocation of wild populations: conservation implications for the genetic diversity of the black-lipped pearl oyster Pinctada margaritifera. Introducing some wild individuals near farms leads to more diverse farmed populations, right? Nope. The farmed populations are way diverse already and if anything the diversity is moving the other way.
- Maize x Teosinte Hybrid Cobs Do Not Prevent Crop Gene Introgression. That’s because the hybrid cobs break apart much more easily than maize.
- Detecting population structure and recent demographic history in endangered livestock breeds: the case of the Italian autochthonous donkeys. Microsatellites confirm existence of 8 breeds of Italian donkey, though there is also significant substructuring within each by farm. This apparently calls for a “synergic management strategy at the farm level,” which basically means using the breed as the unit of conservation but being careful about inbreeding.
- Evolutionary tools for phytosanitary risk analysis: phylogenetic signal as a predictor of host range of plant pests and pathogens. Work out host susceptibility by looking at existing pest preferences and phylogenetic distance from the stuff the pest is known to like.

- Impact of landscape alteration and invasions on pollinators: a meta-analysis. Habitat alteration and invasions equally bad on visitation rates, invasive animals more bad than invasive plants, and disturbance of the matrix more than fragment size. But there are some differences among vegetation types.
- The determinants of leaf turgor loss point and prediction of drought tolerance of species and biomes: a global meta-analysis. Osmotic potential at full turgor could be used to predict drought tolerance across species. Cut a long story short, that simplifies down to salty cell sap, give or take. Good for choosing crop wild relatives to use in breeding for drought tolerance?
- Market-based instruments for biodiversity and ecosystem services: A lexicon. If you want to tell your tradable permits from your reverse auctions. And really, who doesn’t?
- Phenotypic and molecular dissection of ICRISAT mini core collection of peanut (Arachis hypogaea L.) for high oleic acid. Much diversity in oleic acid (O) to low linoleic acid (L) ratio found. Breeders alerted.
- Phenotypic diversity and evolution of farmer varieties of bread wheat on organic farms in Europe. There wasn’t much of it, over 3 years.
- A Comparison of Dung Beetle (Coleoptera: Scarabaeidae) Attraction to Native and Exotic Mammal Dung. They really know their shit.
- Small-scale farming in semi-arid areas: Livelihood dynamics between 1997 and 2010 in Laikipia, Kenya. Life continues to be a bitch, there’s no other way to say it. But when will the people who measure livelihoods measure the diversity of people’s assets as well as their size?
- Climate-associated phenological advances in bee pollinators and bee-pollinated plants. About 10 days over the past 130 years, most of the change since 1970, and bee plants keeping pace with bees.
A diversity of nibbles
Got held up with sickness and overwork, so rather than nibbling, which takes work, ((There are many sources – Pascal, Johnson – for the canonical “Sorry to write such a long letter; I didn’t have time to do a short one.”)) how about a kinda narrative thang?
Starting off with a piece from Agriculture for Impact asking does planting trees compete with planting food?. “It depends,” natch. Richer farmers tend to do well in the particular scheme, which was based on payments for carbon sequestration. The one comment on the post – Planting trees is more profitable than planting food crops – puts in a nutshell the difficulties of improving local food security. Can you buy as much nutrition as you could grow on the same land? Is sequestering carbon considered in the USDA’s new Economic Research Report Rural Wealth Creation: Concepts, Strategies, and Measures? I’ve no idea. Also, on prices and wealth, Marcelino Fuentes calls the do-gooders for their volte-face on high food prices. Surely they’re good for poor farmers? Not any more. and how I remember the squirming when this very topic came up at the FAO in 2008.
In the wake of The Economist’s encomium to Svalbard, the Western Farm Press links that fine safety backup seed bank to the Pavlovsk Experiment Station, calling it “the oldest global seed bank”. Pavlovsk is still under threat, which Svalbard presumably is not, so point taken. But c’mon, people, it is not a seed bank.
And speaking of seeds, Garden Organic in the UK has a new guide to exotica, serving the needs of communities new to the English Midlands who want to grow the stuff they’ve always eaten. I’d have thought they already knew how, but maybe the real point is to harvest that knowledge.
All those communities moving around the place have been known to muddy the linguistic waters around the things they eat; your rocket is my arugula, and neither of us knows what rughetta might be. There’s long been an on-again off-again project at Melbourne University, to compile a multilingual, multi script plant name database, which is useful if you have specific questions. Now comes something that might be altogether more provocative of interesting work: on open data standard for food. I’m not geeky enough to know exactly how it will be useful – for example in citizen science, or global surveys – but I am geeky enough to believe that it will indeed be useful.
Nibbles: Gene, Database, Climate Change, Nutrition, Archaeology, Website, Prices, Svalbard
- Today’s maybe we’ll get some coverage if we link it to hunger and famine press release. Petunia gene.
- Today’s there’s a database for that announcement. FAO’s Horticulture Cultivars Performance Database.
- Today’s impact of climate change on X report. Forest resources in the Caribbean.
- Today’s debunking a crappy piece of nutrition research killjoys. Experts respond to nutrition claims.
- The Archaeobotanist has been going great guns; new book on domestication and millet domestication. We’ll pass on the museum post till we can firm it up.
- IFPRI says let two flowers bloom. Here’s the super-groovy new policy kid on the block for non-policy wonks.
- I’ll see your evil speculators and raise you a rising secular trend in food prices. (See what I did there?)
- With a heavy clunk, The Economist gave Svalbard’s Doomsday Seed Vault a fine 4th birthday present.
Nibbles: Women, Diplomats, Murderers, Speculators, Brainiacs, Participators, Cartographers, Foodographers, Native American agrobiodiversity
- Mo’ women power, mo’ better food security. ILRI leads the pack of CGIAR centres, but there’s loads of stuff elsewhere.
- British diplomat ponders the value of biodiversity.
- Less than a human life, at least in some parts of Brazil.
- Speaking (cynically) of values and prices, informed speculation on speculators is at hand.
- Berries make you brainy; so I guess that reporter hasn’t eaten any lately.
- You too can determine future-oriented research pathways for food security in East Africa, and no need to pig out on berries.
- A kinda sorta interactive map of European agricultural biodiversity. Is it sustainable?
- That map may need a special section for Florence, if one person’s photographic Florentine feast is anything to go by.
- If there were a similar map for the US, it would probably include this kind of thing from the Cherokee.
