- Enhancing the functioning of farm animal gene banks in Europe: results of the IMAGE project. Lots going on, but avian species in particular need more work.
- Conservation and Utilization of Livestock Genetic Diversity in the United States of America through Gene Banking. Over 1,000,000 samples from over 55,000 animals, representing 165 livestock and poultry breeds, collected over 60 years, more than 50% of rare breeds.
- Cryoconservation of Animal Genetic Resources in Europe and Two African Countries: A Gap Analysis. Out of the 2949 breeds registered in DAD-IS, 16% have material in genebanks, but only 4% have enough to allow breed reconstitution.
- Unlocking the origins and biology of domestic animals using ancient DNA and paleogenomics. How we got to the above.

- Wild potato Genetic Reserves in Protected Areas: prospection notes from Los Cardones National Park, Salta, Argentina. Nice combination of in situ and ex situ.
- Agricultural intensification was associated with crop diversification in India (1947-2014). But only at country level, and not by much. At district level, crop diversity went down in rice/wheat areas and up in the south and west as oilseeds and vegetables replaced millet and sorghum. Doesn’t strike me as positive overall, diversity-wise.
- From population to production: 50 years of scientific literature on how to feed the world. Time for a bit of holism.

- Enset‐based agricultural systems in Ethiopia: A systematic review of production trends, agronomy, processing and the wider food security applications of a neglected banana relative. Better data needed, for a start.
- Worldwide Genetic Resources of Duckweed: Stock Collections. 36 species, no less. Need more?
- Realizing hybrids between the cultivated peanut (Arachis hypogaea L.) and its distantly related wild species using in situ embryo rescue technique. You need to apply growth substances to the pollinated flowers.
- The remarkable morphological diversity of leaf shape in sweet potato (Ipomoea batatas): the influence of genetics, environment, and G×E. Genetics controls shape, environment size.
- Adaptation and development pathways for different types of farmers. Watch your context, and don’t forget governance.
- Golden Rice and technology adoption theory: A study of seed choice dynamics among rice growers in the Philippines. They forgot context. And governance. But let the author spell it out in a tweet thread.
Soil biodiversity assessments around the world
Alberto Orgiazzi, who a few months ago summarized global soil biodiversity mapping in a tweet, has done it again:

Time to join efforts indeed.
Nibbles: Cheese history, RethinkX, Cosmopolitan Chicken, Natural capital accounting, Supply chains, Healthy policies, NordGen
- Fruit flies facilitated the birth of the hybrid yeast that made cheese possible. Thanks, fruitfly!
- Ah, but an upgrade is coming: precision fermentation.
- How business can track its effects on biodiversity. Should it want to.
- How to make it easier, more profitable and more sustainable to bring healthy foods to market. Someone mash it up with the above?
- How to design policies for countries seeking to provide healthy diets. Someone mash it up with the above?
- 40 years of NordGen. Happy birthday! Then someone mash it up with the above…
- Celebrating poultry diversity through art. No need for mashing, just celebrate the weirdness.
Brainfood: Accessibility data smorgasbord, Microclimate megadataset, Breeding strategies, Aeroponic cassava, Jatropha conservation, Wheat diversity, Botanic gardens, Polyploid duo, Rhizosphere symbiosis, Selfing niches, Pepper priorities, Eggplant core, Ipomoea evolution, Kenyan supermarkets
- A suite of global accessibility indicators. How long it takes to get from anywhere in the world to settlements of different size. Or took, in 2015.
- A method for computing hourly, historical, terrain‐corrected microclimate anywhere on Earth. Why you might want to move in the first place.
- Genetic strategies for improving crop yields. “Valuable genetic diversity for increasing crop resilience resides in cultivated landraces, heirloom varieties and the wild relatives of crops.”
- A low-cost aeroponic phenotyping system for storage root development: unravelling the below-ground secrets of cassava (Manihot esculenta). But sometimes you have to work hard to get at it: case in point.
- High SNP diversity in the non-toxic indigenous Jatropha curcas germplasm widens the potential of this upcoming major biofuel crop species. And here’s another.
- Genome-wide variation patterns between landraces and cultivars uncover divergent selection during modern wheat breeding. In China and Pakistan anyway.
- Plant populations of three threatened species experience rapid evolution under ex situ cultivation. So don’t cultivate, store seeds instead. Or as well.
- Genes derived from ancient polyploidy have higher genetic diversity and are associated with domestication in Brassica rapa. Polyploidy pre-adapts plants for domestication.
- Genome duplication effects on functional traits and fitness are genetic context and species dependent: studies of synthetic polyploid Fragaria. Case in point.
- A mutualistic interaction between Streptomyces bacteria, strawberry plants and pollinating bees. The rhizosphere protects.
- Do selfing species have greater niche breadth? Support from ecological niche modeling. Yes indeed.
- Modelled distributions and conservation status of the wild relatives of chile peppers (Capsicum L.). 50% are high priority for conservation. No word on their mating systems.
- Construction of a core collection of eggplant (Solanum melongena L.) based on genome-wide SNP and SSR genotypes. From 893 to 100, in 4 geographical clusters.
- A taxonomic monograph of Ipomoea integrated across phylogenetic scales. A whole bunch of new species, and evidence that some 60 species independently developed storage roots before humans were even around. Yes, even sweetpotato.
- Supermarket food purchases and child nutrition in Kenya. Not a bad thing.
Brainfood: Cassava diversity, Landrace diversity double, Soybean oil quality, Cucurbit domestication, Carrot colours, Pharaonic emmer, Teosinte RILs, Chinese pigs, Brazilian apples, Teosinte diversity, Forests & diets, Forest productivity, Agricultural productivity
- A global overview of cassava genetic diversity. The African germplasm is different from the Latin American, but not by that much.
- Genetic variability in landraces populations and the risk to lose genetic variation. The example of landrace ‘Kyperounda’ and its implications for ex situ conservation. Better genetically to conserve landraces as sub-lines. But financially?
- Impact of merging commercial breeding lines on the genetic diversity of Landrace pigs. Above goes for pigs too.
- Selection and Molecular Characterization of Soybeans with High Oleic Acid from Plant Germplasm of Genebank. 3 accessions have interesting variants in the relevant gene.
- Origin and domestication of Cucurbitaceae crops: insights from phylogenies, genomics and archaeology. Lots of different paths to domestication, but all involve loss of flesh bitterness, one way or another.
- Changing Carrot Color: Insertions in DcMYB7 Alter the Regulation of Anthocyanin Biosynthesis and Modification. How the carrot lost its purple.
- A 3,000-year-old Egyptian emmer wheat genome reveals dispersal and domestication history. Most closely resembles modern material from Turkey, Oman and India.
- TeoNAM: A Nested Association Mapping Population for Domestication and Agronomic Trait Analysis in Maize. With added teosinte goodness.
- Adaptive phenotypic divergence in an annual grass differs across biotic contexts. The rhizosphere affects adaptation of teosinte along an altitudinal gradient. We’ll need a Nested Association Mapping Population for that too now, no doubt.
- Population genetics assessment model reveals priority protection of genetic resources in native pig breeds in China. Most breeds have low diversity; Tibetan pigs are an exception.
- A brief history of the forty-five years of the E’AppleBP apple breeding program in Brazil. 27 new varieties seems like pretty good going.
- Testing the Various Pathways Linking Forest Cover to Dietary Diversity in Tropical Landscapes. Sometimes there’s a direct pathway (e.g., consumption of forest food), sometimes an income pathway (income from forest products used to purchase food from markets), and sometimes an agroecological pathway (forests and trees sustaining farm production). And sometimes there isn’t.
- Evolutionary diversity is associated with wood productivity in Amazonian forests. “…greater phylogenetic diversity translates into higher levels of ecosystem function.” No word on its effect on diets.
- Anatomy and resilience of the global production ecosystem. Plenty of words on its effect on diets.
