Transgressive overyielding of soil microbial biomass in a grassland plant diversity gradient. Dead link. More microbial biomass in mixtures of plants than in each of the monocultures. Which I guess is a good thing?- Ecosystem function enhanced by combining four functional types of plant species in intensively managed grassland mixtures: a 3-year continental-scale field experiment. That transgression goes for the yield of the plants too. The mixtures were also more resistant to weed invasion.
- Latitudinal gradients as natural laboratories to infer species’ responses to temperature. Meta-analysis shows that many life history traits vary with latitude, but not necessarily with temperature.
- DNA barcoding for conservation, seed banking and ecological restoration of Acacia in the Midwest of Western Australia. Not quite there yet, is it?
- Preservation of Recalcitrant Seeds. We have the technology. Recalcitrance is not an excuse. And may not be as common as advertised anyway.
- Genetic diversity and relationships in accessions from different cultivar groups and origins in the tree tomato (Solanum betaceum Cav.). It is variable. It originated in Ecuador. Even the press release struggles to say much more than that. They should have asked the mother-in-law.
- Metabolic approaches to understanding climate change impacts on seasonal host-macroparasite dynamics. Fortunately, and yet suspiciously, it is easy to estimate the model parameters even when you don’t have much data.
- Flow and stability of natural pest control services depend on complexity and crop rotation at the landscape scale. You need complexity in both space and time to get the most out of your landscapes.
- Improving fruit and wine: what does genomics have to offer? A lot. But you have to be ready for it.
Heirlooms oversimplified?
Heirloom seeds are usually open-pollinated, meaning that wind or insects fertilize the seed. They’ll breed true to their parent plants, so if you harvest the seeds and replant them you will get the same variety.
Is it just me, or does this strike you as a huge over-simplification — not to say error? And there’s more — lots more — where that came from.
Nibbles: Cornish pasties, Rice and fish, Wheat breeding, Diatribe, Hops, Bean-To-Bar, Geographic indications
- Yes, because the world desperately needs a map of “handheld, filled snacks from around the world.”
- Paddies and aquaculture go well together. But didn’t we know that already? And wait, synergise is a verb?
- Article with interesting-sounding title about the use of IT to monitor wheat diseases has nothing to do with using IT to monitor wheat diseases.
- Oh that’s enough for today, I’m just not in the mood. As you might have noticed.
- No, wait, I feel better now. Ah, the restorative power of beer and genebanks.
- And of chocolate.
- Which does not feature among the first three African PGIs.
Nibbles: Fruit hunters, Organic interview, Hunger review, Jamaican seeds, Project evaluation, Horse domestication, Maize then and now, Impact studies, Seed kits, Amazon ranching, Habitat restoration, Native potato manual, SRI
- CBC documentary on collectors of fruit diversity. Anyone seen it?
- Matthew Dillon of Seed Matters on organic seeds.
- IFAD bigwig deconstructs Conway’s One Billion Hungry. Great summary of 400+ pages. Diversified farming systems are in there, kinda sorta.
- Jamaican bill calls on someone or other to “maximize internal intra and inter-species variation to boost benefits.” They need to fix the title too. It has something to do with the ITPGRFA.
- How to evaluate fisheries and aquaculture projects. Nothing in there about the importance of genetic diversity in these systems, or indeed their possible effects on the biodiversity around them.
- Sculptures of horses with tack from middle of Saudi Arabian desert may push date of domestication way back.
- Maize a staple, not a ceremonial condiment, in early Peruvian coastal civilizations. And also in Timor Leste for that matter. One does worry about those local landraces, though.
- Latest examples of impact of investments in agricultural R&D from EIARD. Includes African indigenous veggies!
- AVRDC sends vegetable seed kits to Mali. Including indigenous species, but apparently only improved varieties.
- Anthropologist goes to Amazon, learns not to look down his nose at ranchers.
- Millennium Seed Bank helping to restore Falkland habitats. That sort of thing can be a business, you know?
- Manual for the conservation and improvement of Chiloe’s native potatoes. Should have something similar for maize in Timor, eh? And African indigenous veggies too?
- You remember yesterday’s Nibble about SRI? Here’s more oil on the fire.
Nibbles: Organic tomato goodness, Golden Rice timeline, Beet nutrient changes, Finger millet intensification, Apple pix, Sourdough fungi, Rotational goodness, Bioversity DG, World Food Prize
- Another view of that organic tomatoes, stress and nutrients study that was all over the place yesterday.
- IRRI provides a reality check on Golden Rice. Maybe they should just have stressed it.
- Speaking of which, have we already linked to this piece on how beet has got poorer in nutrients?
- Thinking of setting up a map portal? Say about the geographic distribution of nutritional problems? Read this first.
- From SRI to SFMI. Yeah, but what is happening to nutrient levels?
- Did we also link to these pretty photos of apples before? Well, I don’t care, it’s worth seeing them again. And just imagine how much the different varieties differ in nutrients.
- How nutritious is sourdough anyway? Anyone?
- Yeah, yeah, but is rotation good for nutrient content?
- Which will all be very interesting to the new Bioversity DG, no doubt.
- Not to mention to some of the potential candidates for the World Food Prize.
