- The importance of scattered trees for biodiversity conservation: A global meta‐analysis. It’s pretty high.
- Origin and diversity of an underutilized fruit tree crop, cempedak (Artocarpus integer, Moraceae). The germplasm collections are not too bad, at least for the cultivated form.
- Genetic diversity of Saudi native chicken breeds segregating for naked neck and frizzle genes using microsatellite markers. The 6 breeds are diverse and show no inbreeding. Yet.
- Conservation of breeds and maintenance of biodiversity: justification and methodology for the conservation of Animal Genetic Resources. Ah, so that’s why they did the above.
- What are palm groves of Phoenix? Conservation of Phoenix palm groves in the European Union. Feral can still be useful.
- Date Palm Agrobiodiversity (Phoenix dactylifera L.) in Siwa Oasis, Egypt: Combining Ethnography, Morphometry, and Genetics. Some locally recognized and named types are in fact collections of genetically distinct clones that somehow go together anyway: call them “ethnovarieties” if you wish. But not feral.
- How to meet the 2020 GSPC target 8 in Europe: priority-setting for seed banking of native threatened plants. 62.7% of European threatened species are already in genebanks, but the others won’t collect themselves. No word on what to do about dates.
- Evolutionary history of the chili pepper Capsicum baccatum L. (Solanaceae): domestication in South America and natural diversification in the Seasonally Dry Tropical Forests. Probably originated in Bolivian Amazonia and inter-Andean valleys.
- Social-ecological outcomes of agricultural intensification. Win-wins are like hen’s teeth.
- Plant breeding and diversity: A troubled relationship? There may be another bottleneck coming.
- Rapid loss of seed viability in ex situ conserved wheat and barley at 4°C as compared to −20°C storage. 4°C is not cold enough for long-term conservation.
- Genetic control of seed shattering during African rice domestication. Multiple genes lead to a range of non-shattering phenotypes.
Nibbles: Cordillera rice, Farmer seed, Toddy audio essay, Eat This Newsletter, Coconut conservation, Australian genebank, Sweet potato diversification, Mungbean income, NERICA impact, Bing cherry, TFP, Conservation evidence, NordGen matters
- Conserving heirloom rice in the Philippines.
- A seed production company run by farmers.
- Tapping toddy. With audio goodness.
- Lots of goodness in Jeremy’s latest newsletter.
- Australia gets serious about coconut conservation in the Pacific and beyond.
- Australia’s own genebanks are very serious. Oh yes indeedy.
- Will sweet potatoes get young people into farming in Kenya? If my nephews are anything to go by, the answer, alas, is no.
- Maybe they should try mungbeans.
- Or NERICA.
- The Bing cherry didn’t help Ah Bing much though.
- Whatever the crop, it’s total factor productivity that you have to watch for.
- And then don’t forget to include whatever intervention you come up with in subject-wide evidence synthesis.
- Prize for best title of the week: “Nordic cooperation on genetic resources – what’s the point?” Nice video.
Brainfood: Rationalizing acquisition, Empowering women, Breadfruit domestication, Rice hybrid sterility, Long-distance crop dispersal, Diversification, African leafy greens, GIAH, Silkworm cryo, Bean in situ
- Molecular markers as a tool for germplasm acquisition to enhance the genetic diversity of a Napier grass (Cenchrus purpureus syn. Pennisetum purpureum) collection. Win-win for the ILRI and Embrapa genebanks.
- Women’s empowerment in agriculture and agricultural productivity: Evidence from rural maize farmer households in western Kenya. 1% increase in women’s empowerment led to a 6-16% increase in maize yields, depending on fanciness of math.
- A transcriptome screen for positive selection in domesticated breadfruit and its wild relatives (Artocarpus spp.). Evidence of selection in 1000 genes.
- A selfish genetic element confers non-Mendelian inheritance in rice. Pollen toxin-antidote genetic system controls hybrid sterility in wild-cultivated crosses.
- Between China and South Asia: A Middle Asian corridor of crop dispersal and agricultural innovation in the Bronze Age. It’s not all demic diffusion.
- Determinants of crop diversification in rice-dominated Sri Lankan agricultural systems. Not everyone can diversify.
- Improving food-system efficiency and environmental conservation using agricultural biodiversity in Busia County: a pilot study. Giving farmers nutritional data increased their cultivation of traditional vegetables, and their income.
- The impacts of farmers’ livelihood endowments on their participation in eco-compensation policies: Globally important agricultural heritage systems case studies from China. Giving farmers money increased their income.
- Conservation of wild silkworm genetic resources through cryopreservation: Standardization of sperm processing. It’s best to recover sperm from the bursa copulatrix and spermatheca of the female moth after mating.
- Short-Term Local Adaptation of Historical Common Bean (Phaseolus vulgaris L.) Varieties and Implications for In Situ Management of Bean Diversity. 3 years of multiplication of heritage varieties in contrasting organic farms leads to genetic changes: it takes a network to truly conserve.
Brainfood: Sustainable Brazil, Epigenetic variation, Global conservation, Rice nutrition, Austronesian societies, Saharan domestication, GM wheat, Smallholders, Bos introgression
- Sustainable diet from the urban Brazilian consumer perspective. Healthiness, basically.
- Comparison of the Relative Potential for Epigenetic and Genetic Variation To Contribute to Trait Stability. Genetic >> epigenetic.
- Global mismatch of policy and research on drivers of biodiversity loss. Except for climate change.
- Carbon dioxide (CO2) levels this century will alter the protein, micronutrients, and vitamin content of rice grains with potential health consequences for the poorest rice-dependent countries. And not in a good way. But some variation among varieties = breeding opportunity?
- Coevolution of landesque capital intensive agriculture and sociopolitical hierarchy. Among Austronesian-speaking societies, no evidence that agricultural intensification drives social complexity; if anything, it’s the other way around.
- Plant behaviour from human imprints and the cultivation of wild cereals in Holocene Sahara. Weediness has been good to humans in the past.
- Gene Flow in Genetically Modified Wheat. Would probably only be a problem within fields.
- How much of the world’s food do smallholders produce? FAO: 70%. New paper: 30-34%.
- Pervasive introgression facilitated domestication and adaptation in the Bos species complex. Miscegenation has been rampant.
Nibbles: Konzo double, ANI, ICRISAT genebank, World Potato Congress, Coffee sequence, Food Forever job
- The fascinating story of konzo, nicely told.
- You’ll remember my take on that, of course.
- Speaking of my take, on the release of the Access to Nutrition Index I ask: cui bono genebanks?
- Somebody mention genebanks? Yes, ICRISAT.
- Consider the beauty of the humble potato.
- Nobody ever calls coffee humble.
- Wanna tell the world about any of the above?
