- 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.
Nibbles: All singing and dancing, FAO meets Big Data, Clone this, Patent nonsense, Frozen fish
- Fisherfolk of the Amazon landed on film. But do they sing about it? (And it’s not just an Amazon thing, this dancing and singing about agrobiodiversity. Not by any means.) And should they be doing more slashing-and-burning?
- FAO to put all its data in one basket. But including AnGR? WIEWS? One asks more in hope than expectation.
- One of the many challenges of vegetatively propagated crops (like potatoes): rapid multiplication. (Well, they could always do an SNP-based tetraploid map of the damn things, couldn’t they.) No such problems with seeds, of course.
- There’s been a rapid increase in the patenting of adaptation-related traits, and the private sector in industrialized countries is mainly responsible. Well there’s a surprise. But was that discussed at the CCAFS meeting on breeding objectives for Africa? And it’s just as well to remember that it’s not just breeding that’s needed. Oh, but by the way, you better grab those adaptations while you can…
- Regional SE Asian fish genebank proposed. That I’d love to see. Maybe they could share germplasm with, I dunno, Chicago? And not just.
Multidisciplinary taro book on the way
The National Museum of Ethnology in Osaka has just announced the publication of what promises to be a fascinating book on taro:
M. Spriggs, D. Addison and P. J. Matthews (eds) (2012) Irrigated Taro (Colocasia esculenta) in the Indo-Pacific: Biological, Social and Historical Perspectives (Senri Ethnological Studies 78). Osaka: National Museum of Ethnology. 363 pp., with index.
According to one of the authors, “[t]his map from the preface shows main geographical coverage (areas 1 – 10) of the volume (there is also some extension to China and mainland SE Asia).”
All the chapters will soon be available on the Museum’s website, so keep a lookout.
Nibbles: Anna Laurent, Sequencing, Gossypium, Capsicum, Native Americans, Journal, Genebank, Hairy fruit, JIC, Tasty tulips
- Design guru talks botany. Latest plant getting the treatment is the Hawaiian Cotton Tree. Which, despite its name, really is a (remote) cotton wild relative.
- What has Next Generation Sequencing ever done for me? And what you should know about how it works.
- And here’s an example of it at work: different cultivated cotton species have behaved differently, genetically speaking.
- That used ancient DNA, this one didn’t, but I guess a future one on chiles might. LATER: Ooops, just realized this is old. So what was it doing in my RSS feed?
- Speaking of chiles, here’s a couple of more things on Native American agriculture.
- Free access to the first issue of volume 20 of Journal for Nature Conservation for the next 12 months.
- Rebuilding the genebank in Ivory Coast.
- Discovering the wonders of the coconut. Their headline, not mine.
- The latest news from the John Innes Centre’s genebank.
- Fancy a tulip? To eat, that is.
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.
