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.
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: UK horticulture funding, AVRDC, Biofortification, SRI debate, Stressed bees, Nutrient decline, Beneficial viruses, DNA for dummies, Chaffey, Cow genebank, Organic network
- For UK horticulturalists in need of cash. Wonder if that includes the rosemary collection.
- I’m pretty sure it doesn’t include AVRDC.
- Who would no doubt agree with Mark Lynas that “No-one disputes that a balanced and nutritionally-adequate diet is the best long-term solution to vitamin A deficiency and malnutrition in general.” And be as puzzled as the rest of us for the relative lack of funding for research on such a diet.
- A discussion of why mainstream agricultural science hasn’t got the message across about SRI, courtesy of Facebook. Yeah well, the whole concept of basing interventions on, you know, evidence, is not exactly mainstream. Just ask the balanced and nutritionally-adequate diet guys.
- Bees are stressed out, the poor things.
- Creative Commons graphs on changes in vegetable nutrient content.
- Not all plant viruses are bad.
- Pat Heslop-Harrison talks DNA, with his usual extraordinary fluency, from 11 mins in.
- Plant Cuttings! Everything from the botany of food to transcription factors for C4 photosynthesis.
- Cow genebank proposed.
- IFOAM gets a TIPI. Vandana Shiva no doubt ecstatic.

- Vinecology: pairing wine with nature. You can have wine, and drink it too.
- The role of wild vegetable species in household food security in maize based subsistence cropping systems. Is very significant, in South Africa.
- Does land abandonment decrease species richness and abundance of plants and animals in Mediterranean pastures, arable lands and permanent croplands? Well, we wont know until these guys do their review, as described here. What a weird paper.
- Development of a core collection of Triticum and Aegilops species for improvement of wheat for activity against chronic diseases. Used GRIN to select material from areas varying in cancer prevalence.
- Patterns of Genetic Variation across Altitude in Three Plant Species of Semi-Dry Grasslands. Populations on the edge altitudinally are not on the edge genetically.
- Is community persistence related to diversity? A test with prairie species in a long-term experiment. Yes. If by persistence you mean that the community resists invasion better after you stop weeding it.
- Agricultural intensification in Brazil and its effects on land use patterns: An analysis of the 1975-2006 period. Intensification leads to decreased expansion only where land is scarce, i.e. NOT at the frontier.
- Long-term Changes in Fruit Phenology in a West African Lowland Tropical Rain Forest are Not Explained by Rainfall. I don’t get it. Maybe someone can explain it to me.
- Differences in gene expression within a striking phenotypic mosaic Eucalyptus tree that varies in susceptibility to herbivory. One tree, 2 chemotypes, many genes differentially expressed, 10 SNPs that could affect secondary metabolism.
