- Genome-wide comparative diversity uncovers population structure, global distribution, and targets of selection in hexaploid oat. A worldwide survey reveals how oat diversity is structured, spread, and shaped by breeding, helping pinpoint untapped genetic resources for future improvement.
- Genomic diversity and the domestication history of cotton (Gossypium hirsutum). Its genome traces cotton’s journey from its wild origins in Mesoamerica while documenting the genetic narrowing that accompanied domestication.
- Genetic architecture of sugarcane traits in a polyploid genomics framework. New genomic tools finally begin to untangle the diversity of one of agriculture’s most genetically complex crops, exposing the basis of traits breeders have long selected largely in the dark.
- Projected warming will exceed the long-term thermal limits of rice cultivation. Rice has historically thrived within remarkably stable climatic boundaries. Those boundaries are now on course to be crossed across major growing regions, with profound implications for global food security. Diversity to the rescue?
- An inter-specific Amaranthus pangenome captures genetic variation potentially underlying key leafy vegetable traits in this underutilised crop. A rich reservoir of previously hidden diversity emerges from across multiple cultivated amaranths, offering breeders new options for improving a neglected but nutritious vegetable.
- Impact of gardening and nutrition support provided to women in refugee camps in Cox’s Bazar, Bangladesh. Even in one of the world’s most challenging humanitarian settings, greater interspecific crop diversity translated into better diets, improved food security, and enhanced wellbeing.
- Designing perennial crop-based agroforestry systems: specificities, challenges, and opportunities. Diversification does not stop at the field edge: how perennial crops can be combined with trees to deliver productive, resilient, and biodiversity-friendly farming systems.
- Towards Nature Positive supply chains: From biodiversity commitments to organisational action. What would it take to move biodiversity from corporate promises to business practice? Maybe the above examples can help turn aspiration into measurable action.
Brainfood: Indigenous edition
- Rapid adaptive increase of amylase gene copy number in Indigenous Andeans. Indigenous Andean populations evolved exceptionally high copy numbers of the AMY1 salivary amylase gene, likely linked to long-term adaptation to starch-rich diets associated with potato domestication roughly 10,000 years ago.
- Horse genetics, archaeology, and the beginning of riding. Horse domestication was not a sudden genetic event beginning around 2200–2100 BCE, but a long and regionally varied process in which Indigenous Eurasian pastoralists progressively managed, rode, milked and selectively bred multiple horse lineages over many centuries, transforming mobility and social organization well before the rise of the dominant modern domestic horse lineage.
- Bridging biodiversity and food systems: A nationwide synthesis of non-conventional food plants (PANCs) in Brazil. Brazil’s non-conventional food plants (PANCs) and associated Indigenous and traditional knowledge could help build more diverse, climate-resilient and socially inclusive food systems while strengthening biodiversity conservation, rural livelihoods and public food programs.
- Indigenous Wisdom for a Changing World: Bridging Traditional Ecological Knowledge and Biodiversity Conservation. Sacred groves and other community-managed landscapes in central Ethiopia conserve high levels of biodiversity through Indigenous institutions, ritual practices and traditional ecological knowledge, suggesting that effective conservation depends on treating cultural stewardship systems as integral to ecological resilience rather than as secondary to scientific management.
- When Knowledge Isn’t Free: Legal and Ethical Imperatives of Protecting Indigenous Intellectual Property. There’s a persistent mismatch between Western intellectual-property regimes and Indigenous concepts of collective ownership, biocultural heritage and intergenerational custodianship of knowledge, and that’s unfair.
- Crediting and citing Indigenous Knowledges within research. Biodiversity conservation becomes more effective when Indigenous scientists and communities participate as equal partners rather than merely as local stakeholders or informants.
Brainfood: Silk Road, Wheat domestication, Peanut domestication, Olive wild relatives, Pearl millet movement, Maori horticulture, Wild meat, Fermentation
- Domesticated: How Cultivated Species Altered Ancient Silk Road Societies. Different stages of adopting and intensifying the use of domesticates (livestock, horses, and later crops) reshaped economies, mobility, and social organization in north-central Asia, ultimately enabling the emergence of the Silk Road. So domesticated species were as active drivers of Eurasian historical development as of prehistory.
- Ancient grains illuminate the mosaic origin of domesticated wheat. Domesticated wheat arose through repeated hybridizations between distinct wild populations carrying complementary non-shattering spike mutations, followed by ongoing gene flow and regional adaptation, making domestication a prolonged and interconnected process. Long before the result got to the Silk Road.
- A single hybrid origin of cultivated peanut. Domestication of the peanut seems to have been easier than that of wheat.
- A synthetic eco-evolutionary proposal for the conservation of wild relatives of the olive tree. If we ever have to re-domesticate the olive, we should make sure these 53 wild populations are conserved.
- Westward expansion of pearl millet agriculture into the Lac de Guiers basin, Senegal, by c. AD 200. I wonder what the Sahelian equivalent of the Silk Road was.
- Horticultural intensification and plant-based diets of 18th century CE Waikato Māori in Aotearoa New Zealand. At least some Maori ate predominantly sweet potato and taro during the Traditional Period. Which of course were brought to Aotearoa via the ara moana, which, stretching a point, is the South Pacific equivalent of the Silk Road.
- Increase in wild animal consumption across Central Africa. Yeah, but who needs domesticated species anyway.
- Fermentation as food pedagogy: insights into how teaching fermentation facilitates engagement with the food system. Are fermentation microbes domesticated?
Brainfood: Animal diversity edition
- Livestock grazing boosts plant diversity in the Greater Serengeti–Mara Ecosystem. Livestock can be good for biodiversity conservation. But can its diversity be conserved too? Let’s see.
- Conservation and Management of Animal Genetic Resources in the Context of African Livestock Production Systems: The Case for In Situ and Ex Situ Conservation. “The multi-stakeholder breeders-researchers-decision-makers approach remains the most robust solution for sound management and preservation of biological units.” What, no farmers and local communities? No, that’s unfair: community-based conservation is discussed. But it doesn’t feel as central to the whole thing as it should be, somehow.
- Genetic Diversity, Adaptation, Wild Introgression, and Coat Color Mutation of Golden Yak. After all, local communities have maintained the golden yak reasonably well.
- Caprine dairy exploitation on the Iranian Plateau from the seventh millennium BC. Not to mention goats in Iran, and for thousands of years…
- Old goats: 3,000 years of genetic connectivity of the domestic goat in Ireland. …and in Ireland, though for not quite as long, admittedly.
- Dogs were widely distributed across western Eurasia during the Palaeolithic. And local communities have been managing dog populations since way before farming even.
- The dispersal of domestic cats from North Africa to Europe around 2000 years ago. Also, local communities managed early cats separately in the Levant and Egypt. Much later than dogs, but that’s cats for you.
- A microbiome catalog of Chinese traditional artisanal cheeses provides insights into functional and microbial diversity. And don’t forget to conserve the associated microbiome too. I wonder what golden yak cheese is like.

- The genomic footprints of wild Saccharum species trace domestication, diversification, and modern breeding of sugarcane. The genome of modern sugarcane is a mosaic of wild introgressions, including one from an unknown source.
- Evolutionary histories of functional mutations during the domestication and spread of japonica rice in Asia. Selection by biotic stresses acted differently on standing variation in rice across geographic regions. Colour me surprised.
- Ancient DNA from lentils (Lens culinaris) illuminates human-plant-culture interactions in the Canary Islands. Local lentils trace back a thousand years in the Canaries.
- An olive parentage atlas: founder cultivars, regional diversification, and implications for breeding programs. Modern cultivars derive from a surprisingly small set of founding genotypes…
- Intraspecific variation and phenotypic plasticity of olive varieties in response to contrasting environmental conditions. …but cultivated olives maintain high within-species variation and plasticity, enabling adaptation across Mediterranean environments.
- Deciphering the Origins of Commercial Sweetpotato Genotypes Using International Genebank Data. One Brazilian sweetpotato traced back to a CIP accession with a different name, but others did not match anything in the genebank.
- Exploring genetic diversity and selective signatures, a journey through Colombian cassava’s landscape. Colombia’s farmers and environments have shaped its cassava diversity. No word on whether any of it traces back to the CIAT genebank.
- Novel germplasm of tepary and other Phaseolus bean wild relatives from dry areas of southwestern USA. The available genepool for bean breeding gets a welcome boost.
- Insight into root system architecture of buckwheat through genome-wide association mapping-first study. Want drought-resilient, high-yielding buckwheat varieties? Here are the genes — and genotypes — to play with. So the available genepool doesn’t need a boost?
- Non-destructive prediction of nitrogen, iron and zinc content in diverse common bean seeds from a genebank using near-infrared spectroscopy. High-throughput, non-destructive phenotyping methods capture nutritional trait variation across a bean core collection. Wild teparies unavailable for comment.
- Germplasm exploration and digital phenotyping reveal indigenous diversity and farmer preferences in pigeon pea (Cajanus cajan (L.) Millsp.) for climate-smart breeding. Not all phenotyping can be high-throughput, but that doesn’t mean it’s not useful, at least in pigeon peas.
- Agricultural landscape genomics to increase crop resilience. Could have been applied to all of the above, I guess.
