- Genome-wide molecular diversity analyses identify wild Cicer as reservoirs of variations for chickpea improvement. Wild relatives of chickpea harbour a wealth of genetic variation that has yet to be exploited by breeders. But it’s mainly within species.
- Genetic and Morphological Diversity in Spontaneous Populations of Brassica rapa: How Do Feral Populations Differ From Wild Ones? When a crop escapes cultivation, does it become wild again? Apparently not. Pity.
- Genetic structure of traditional cacao reveals four new genetic lineages in indigenous Amazonian sites in Peru. Genetic analysis of traditional cacao maintained by Indigenous communities in the Peruvian Amazon uncovers four previously undescribed genetic lineages.
- Contrasting germplasm composition and propagation practices in the two major cacao-growing areas in Panama. Two of Panama’s principal cacao-growing regions have developed markedly different genetic profiles, reflecting both the varieties farmers cultivate and how they propagate them. I think they have been previously described though.
- Ecological multifunctionality of watersheds increases with tree species richness. Watersheds planted with a greater diversity of tree species perform better across multiple ecological functions simultaneously, including nutrient cycling, soil protection and water regulation.
- Nutrition sensitive poverty and its correlates in Papua New Guinea: incorporating healthy diet targets into poverty measurement. Conventional poverty measures ask whether people can afford basic necessities. Why not ask a more demanding question: can they afford a healthy diet? Hopefully meaning a diverse one.
Brainfood: Easter Island coffee, Sword bean, Sweetpotato names, Colombian potatoes, Nut grass, Market access, Pollinators, Seed microorganisms
- An insular in situ Coffea arabica resource from Rapa Nui (Easter Island): SSR uniformity and biochemical evaluation of material consistent with the Typica lineage. Coffee growing on remote Rapa Nui appears to represent a remarkably uniform population closely related to the historic Typica lineage. Not diverse doesn’t necessarily mean not interesting.
- Farmer knowledge, management practices, and seed morphological diversity of sword bean (Canavalia gladiata) in Côte d’Ivoire. Growers recognize, manage and maintain morphological variation in sword bean, a legume that could be more utilized.
- Consistency of farmer-named sweet potato cultivars and their physicochemical and color differentiation within a production region. While local naming systems are generally meaningful, they don’t always map perfectly onto measurable physicochemical and colour traits.
- Harnessing the Genetic Diversity of the Colombian Central Collection of Potatoes to Dissect Pigmentation Genomics in Andigenum Landraces. Colombia’s collection helps explain colourful potatoes.
- Novel food ingredients from Cyperus rotundus: an ancient famine food and the world’s most pernicious weed comes back to the table. One of the world’s most notorious weeds may also be an overlooked food crop, and a potential source of novel food ingredients. An opportunity weed?
- Market remoteness and the production–diet association in smallholder food systems: Evidence from rural Nepal. Growing a diverse range of crops does not always translate into a more diverse diet. In Nepal, the relationship depends strongly on market access, highlighting the importance of infrastructure alongside agricultural diversification. Ok, forget the nut grass then, at least far from markets.
- Pollinators support the nutrition and income of vulnerable communities. Pollinator diversity makes important contributions to both dietary quality and household incomes among vulnerable communities.
- Seed ageing increases the influence of native microorganisms on germination. As seeds deteriorate, their naturally associated microorganisms play an increasingly important role in determining whether they successfully germinate. Of course microorganism diversity had to get a look-in too.
Brainfood: Unusual data edition
- The Broad Spectrum Species: Plant Use and Processing as Deep Time Adaptations. Hundreds of plant species, many now forgotten, show up in archaeological assemblages stretching back tens of thousands of years. Exploiting an astonishing diversity of plants was a fundamental human adaptation long before agriculture. And the data was kinda always there.
- Evaluating cultivars for pollinator gardens. Some ornamental cultivars attract more pollinators than the wild plants they were bred from. The relationship between genetic modification through breeding and ecological function is not always straightforward. And I now want to see the descriptor “pollinator attractiveness” in evaluation datasets.
- Chemotypic Diversity and Integrated Metabolic Profiling of Myrtle (Myrtus communis L.) from Mediterranean Turkey. Dozens of different chemical compounds vary dramatically among individual myrtle plants that look much the same to the naked eye.
- Essential oil composition and ethnobotanical survey of male and female Juniperus seravschanica Kom. (Cupressaceae) in Iran. Traditional knowledge and chemical profiling show that juniper male shoots, female shoots and cones each produce distinct blends of essential oils, exposing a surprising layer of sex-linked diversity within a single species.
- Earth Metabolome and Digital Botanical Gardens Initiatives: Chemodiversity Knowledge for Biodiversity Conservation. Millions of plant-produced molecules remain undocumented, forming an invisible dimension of biodiversity. We need global digital infrastructures to catalogue this vast reservoir of chemodiversity before it disappears. Of course we do.
- Herbaria Provide a Valuable Resource for Obtaining Informative mRNA. Decades-old herbarium specimens still contain usable messenger RNA, opening the door to studying historical patterns of gene expression from preserved plant collections.
- The Politics of Open Infrastructures: Power, Governance, and Justice in Digital Knowledge Practices. Data infrastructures may be open, but control over them often is not. And that probably goes even more for the unusual sorts of data represented by the above papers than for the crop diversity data we normally deal with here.
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?
