- The Mystery of Black Rice: Food, Medicinal, and Spiritual Uses of Oryza glaberrima by Maroon Communities in Suriname and French Guiana. There’s a rich oral history of African rice in Maroon communities, but that doesn’t mean either the traditional knowledge or diversity of the crop is safe.
- The Invisible Tropical Tuber Crop: Edible Aroids (Araceae) Sold as “Tajer” in the Netherlands. Another example of traditional knowledge on crops surviving far from their home.
- Rethinking Pliny’s “Sicilian Crocus”: Ecophysiology, Environment, and Classical Texts. There might have been two distinct saffron species in ancient Sicily. Another way of recovering traditional knowledge is by reading ancient texts.
- Trees, terraces and llamas: Resilient watershed management and sustainable agriculture the Inca way. The sedimentary record can be used to recover traditional knowledge too. No word on what ancient text have to say, but I’m sure it’s something.
- Yield, growth, and labor demands of growing maize, beans, and squash in monoculture versus the Three Sisters. Sometimes traditional knowledge can use a helping hand from scientists. And vice versa.
- Interdisciplinary insights into the cultural and chronological context of chili pepper (Capsicum annuum var. annuum L.) domestication in Mexico. About the only thing that’s missing here is traditional knowledge.
- Afro-Indigenous harvests: Cultivating participatory agroecologies in Guerrero, Mexico.
Makes one wish these authors had been involved in the pepper study above. - Tradeoffs between the use of improved varieties and agrobiodiversity conservation in the Sahel. The effect of improved varieties on local landraces (and presumably associated traditional knowledge) is different for pearl millet and groundnut, and for Mali and Niger.
- Illuminating the multidimensional contributions of small-scale fisheries. I’m sure lots of traditional knowledge is involved.
- Satellite imagery reveals widespread coconut plantations on Pacific atolls. They could have just asked the small-scale fisherfolk, but ok.
Brainfood: Diversity patterns double, Diversification drivers, Polish genetic erosion, Tibetan naked barley diversity, Indian sorghum diversity, Do novo domestication, Eggplant tree, Banana diversity, Pearl millet diversity, Pigeon pea genome, Grasspea genome, Jersey bull diversity
- Floristic classifications and bioregionalizations are not predictors of intra-specific evolutionary patterns. You can’t use spatial structures in interspecific diversity to predict spatial structure in instraspecific diversity. Gotta do the hard work, there are no shortcuts.
- Intraspecific trait variability in wild plant populations predicts neither variability nor performance in a common garden. You can’t use intraspecific diversity in wild populations to predict how those populations will do elsewhere. Gotta do the hard work, there are no shortcuts.
- Farming for the future: Understanding factors enabling the adoption of diversified farming systems. Access to extension services, strong social networks, and perceived environmental benefits contribute to the diversification of farming systems, but their effects are context-specific. So yeah, you guessed it, you still gotta do the hard work.
- Changes in Plant Genetic Resources in the Southeast Region of Poland from the 1980s to 2023. I wonder which one(s) of the above has been missing in the Lubelskie Voivodeship.
- Abundant Genetic Diversity Harbored by Traditional Naked Barley Varieties on Tibetan Plateau: Implications in Their Effective Conservation and Utilization. I wonder which one(s) of the above has been most effective in the Tibetan Plateau.
- Genetic diversity in in situ and ex situ collections of sorghum [Sorghum bicolor (L.) Moench] landraces. I wonder which one(s) of the above has been most effective in norther Karnataka.
- Enhancing food security amid climate change through rewilding and de novo domestication. Sounds like hard work. But worth doing.
- Characteristics of the ET, a new species created by interspecific hybridization of two wild eggplants. Sounds like hard work. But worth doing?
- Painting the diversity of a world’s favorite fruit: A next generation catalog of cultivated bananas. Chromosome painting, that is. Definitely worth doing.
- Delineation of selection efficiency and coincidence of multi-trait-based models in a global germplasm collection of pearl millet for a comprehensive assessment of stability and high performing genotypes. Stable AND high-yielding? Sounds like the hard work has been done.
- Chromosome-scale reference genome of an ancient landrace: unveiling the genetic basis of seed weight in the food legume crop pigeonpea (Cajanus cajan). Now for the hard work…
- A chromosome-scale reference genome of grasspea (Lathyrus sativus). Now for the even harder work…
- Assessment of genetic diversity, inbreeding, and collection completeness of Jersey bulls in the US National Animal Germplasm Program. I suspect it will be hard work, but don’t forget the low merit bulls. And that probably goes for plants too.

Brainfood: Cattle domestication double, Sheep domestication, Lomas in Peru, Sweet potato in Aotearoa, Bananas in SE Asia, African wild eggplants, Brassicaceae conservation review, Vanilla in Madagascar
- Global dispersal and adaptive evolution of domestic cattle: a genomic perspective. The scope of adaptation is pretty amazing, and has been aided by introgression from wild relatives.
- The genomic natural history of the aurochs. Which is just as well because the initial diversity of the domesticate was probably rather limited, at least in Europe.
- The Population History of Domestic Sheep Revealed by Paleogenomes. Early domesticated sheep genomes were pretty dynamic too, sometimes in parallel with shepherds and sometimes not.
- Late pre-Hispanic fog oasis settlements and long-term human occupation on the Peruvian central coast from satellite imagery. No cattle or sheep in pre-Hispanic lomas, but plenty of camelids and crops.
- American sweet potato and Asia-Pacific crop experimentation during early colonisation of temperate-climate Aotearoa/New Zealand. One of those crops was in Aotearoa by the 14th century, which is amazing.
- Musa species in mainland Southeast Asia: From wild to domesticate. Even the very wild species are affected by human use.
- Landscape genomics reveals genetic signals of environmental adaptation of African wild eggplants. Environment is not the main driver of selection, but still pretty important and thus useful in breeding. Kinda like cattle?
- Current status of global conservation and characterisation of wild and cultivated Brassicaceae genetic resources. Gotta conserve those wild relatives probably though, if they are to be used.
- Genome-wide assessment of genetic variation and population structure in cultivated vanilla from Madagascar. The results of a breeding programme 80 years ago involving wild relatives can be seen in the current structure of diversity.
Brainfood: Food systems, Micronutrients, Animal-source foods, Dietary diversity, Opportunity crops, Traditional landscapes, Gastronomic landscapes, Opportunity crops, Biofortification, Fermentation
- Global and local perspectives on food security and food systems. Six experts have their say on how to transform food systems, and dietary diversity seems to be a common (though not a universal) theme. Let’s dig a little deeper into that.
- Global estimation of dietary micronutrient inadequacies: a modelling analysis. A lot of people could probably do with eating more fruits and vegetables, for example.
- Plant-based diets–impacts of consumption of little or no animal-source foods on human health. Some people could probably do with eating more animal-source foods, though. Well, that’s diversity too.
- The association between crop diversity and children’s dietary diversity: multi-scalar and cross-national comparisons. In some places, growing more diverse crops is associated with eating more diverse diets; in other places, not so much. Damn you, nuance!
- Revive and Thrive: Forgotten Crops for Resilient Food Systems. Fortunately, there are more advantages to growing more diverse crops than its possible positive effect on diet diversity…
- Why traditional rural landscapes are still important to our future. …yes indeed there are, especially if they are grown in diverse landscapes.
- Nurturing gastronomic landscapes for biosphere stewardship. The hallowed craft of cooking can help realize those advantages.
- NUS so fast: the social and ecological implications of a rapidly developing indigenous food economy in the Cape Town area. However, growing more diverse crops can have downsides, celebrity chefs etc. notwithstanding.
- Assessing realized genetic gains in biofortified cassava breeding for over a decade: Enhanced nutritional value and agronomic performance. Breeding crops for higher nutritional value comes at a yield price. Which presumably, in some places, for some people, may be worth paying, give all the uncertainties above?
- The future is fermented: Microbial biodiversity of fermented foods is a critical resource for food innovation and human health. Or, we could all ferment more. And maybe get drunk.
