- 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.

- The pros and cons of heritage varieties, according to an American farmer.
- Did the ancient Romans have heritage apples?

- Old shipwrecked rye seeds may end up in whiskey. Best place for them.
- Old Serbian grapevine herbarium samples should stay right where they are.
- Old horses most certainly did not stay where they were. But where was that exactly?
- Not sure where old bottled fruit from Washington’s estate will end up. The DNA lab maybe, like those Serbian grapevines?
- There’s going to be a Worldwide Day of Botanical Art on May 18, 2025. Rejoice.
- Decolonizing food insecurity in West Africa.
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: Beverage edition
- Crop-to-wild gene flow in wild coffee species: the case of Coffea canephora in the Democratic Republic of the Congo. DNA bits diagnostic of domesticated coffee are finding their way into wild rainforest populations, but not all that much.
- The genome and population genomics of allopolyploid Coffea arabica reveal the diversification history of modern coffee cultivars. Diversity was already pretty low in pre-domestication wild arabica, and continued going downhill after that. Time to re-synthesize the crop, I say.
- Beyond the Orthodoxy: An Overview of the Potential of ‘Other’ Coffee Species for Crop Use and their Associated Challenges. All well and good, but don’t forget there’s more to coffee than just arabica and robusta.
- Advancing Coffee Genetic Resource Conservation and Exchange: Global Perspectives and Strategies from the ICC 2024 Satellite Workshop. Time to properly secure all coffee diversity in genebanks, and that includes sorting out ABS.
- Expanding the cacao group: three new species of Theobroma sect. Herrania (Malvaceae: Byttnerioideae) from the Western Amazon Basin. Plenty of “other” cacao species too, and more coming.
- Seed morphometrics unravels the evolutionary history of grapevine in France. There was wild-domesticate geneflow in early grapevines in France as well as in robusta coffee in the DRC, and you don’t need to trace bits of DNA to prove it.
- Characterization and analysis of a Commiphora species germinated from an ancient seed suggests a possible connection to a species mentioned in the Bible. Thousand-year-old seed is a distinct and possibly long-lost species of myrrh. Which ok is not a beverage but still vaguely liquid, at least initially.
- Sesame, an Underutilized Oil Seed Crop: Breeding Achievements and Future Challenges. Ok, since we’re doing liquid-producing crops, let’s include this review of sesame improvement. Lots of wild species to use. No word on wild-domesticate geneflow though.
Brainfood: Pacific plant use, Rapa Nui crops, E African crops, Cotton domestication, Fertile Crescent Neolithic, Dutch Neolithic, S Italy crops, Rice domestication, Maize domestication
- Human dispersal and plant processing in the Pacific 55 000–50 000 years ago. There was more to the peopling of the Pacific than seafaring.
- Identification of breadfruit (Artocarpus altilis) and South American crops introduced during early settlement of Rapa Nui (Easter Island), as revealed through starch analysis. Though seafaring took these people all the way to South America, it sees.
- Early agriculture and crop transitions at Kakapel Rockshelter in the Lake Victoria region of eastern Africa. A bit like Rapa Nui, Lake Victoria got crops from both west and east over time.
- Cotton and post-Neolithic investment agriculture in tropical Asia and Africa, with two routes to West Africa. Funny they didn’t find cotton at the Lake Victoria site.
- Drawing diffusion patterns of Neolithic agriculture in Anatolia. Itinerant expert harvesters spread agriculture into Anatolia. Maybe around Africa too, who knows.
- Early animal management in northern Europe: multi-proxy evidence from Swifterbant, the Netherlands. Early farmers in northern Europe managed separate herds of cattle in different ways alongside crops. What, itinerant expert livestock herders too?
- Introduction, spread and selective breeding of crops: new archaeobotanical data from southern Italy in the early Middle Ages. Sicily is a bit like Rapa Nui and Lake Victoria.
- Rice’s trajectory from wild to domesticated in East Asia. Rice domestication pushed back to about the same time as the Fertile Crescent. No word on the role of expert harvesters.
- Archaeological findings show the extent of primitive characteristics of maize in South America. Maize arrived in lowland South America in a pre-domesticated state, and stayed like that for a long time. That’s a long way for expert harvesters to go.
