Check out how the U.S. National Herbarium is digitizing its specimens. Wild.
Brainfood: Rice domestication, Roman wine, Dog domestication, Earth ovens, Forest orchards, Saffron origins
- The Fits and Starts of Indian Rice Domestication: How the Movement of Rice Across Northwest India Impacted Domestication Pathways and Agricultural Stories. While cultivation of (indica) rice in South Asia began in the Ganges around 6500 BC, its domestication really speeded up 3000 years later in the Indus.
- Archaeobotanical and chemical investigations on wine amphorae from San Felice Circeo (Italy) shed light on grape beverages at the Roman time. In the second century BC the ancient Romans may have traded a medicinal wine made from wild or semi-domesticated grapevines. I wonder how it would have gone with a nice risotto.
- Grey wolf genomic history reveals a dual ancestry of dogs. Either dogs were domesticated independently in E and W Eurasia and then the two lineages merged, or they were domesticated in the E and then there was geneflow from wild dogs. Sounds a bit like rice actually. ((No, really, check it out. Japonica gets domesticated in one place, then taken to another place where it gets into geneflow with indica, which is being domesticated elsewhere. Only difference is that 2 different wild species are involved, rather than just a single wild wolf species. Also maybe echoes of what happened in tomato too?))
- Bulbs and Biographies, Pine Nuts and Palimpsests: Exploring Plant Diversity and Earth Oven Reuse at a Late Period Plateau Site. For 2000 years Native Americans returned to specific food processing sites dug into the soil to cook up a storm. No word on the use of wild grapevines.
- Coupled archaeological and ecological analyses reveal ancient cultivation and land use in Nuchatlaht (Nuu-chah-nulth) territories, Pacific Northwest. Native Americans nurtured forest gardens to enrich them with edible species. Including wild apples though again not wild grapevines apparently.
- Ancient Artworks and Crocus Genetics Both Support Saffron’s Origin in Early Greece. Ok now everything is in place for a nice risotto alla Milanese with a Falanghina at the House of the Tragic Poet.
Returning to recollecting
We’ve referred to Project Baseline here a couple of times, but always somewhat desultorily. But I think that needs to end now that the project hit the big time with a shoutout in Gizmodo.
Based at the University of Minnesota Duluth, Project Baseline re-collects seeds multiple times from the same sites to see how populations change genetically and phenotypically.
In the Resurrection Approach, dormant ancestors are reared in a common garden with contemporary descendants. The Project Baseline collections are designed to maintain the genetic structure of populations to facilitate researchers utilizing the resurrection approach. Seeds are collected and stored separately by maternal plant from up to 200 individuals per population. After collection, seeds were cleaned and [conserved] at the NLGRP.
That phrase “reared in a common garden” is doing a lot of work, as the flowchart in a 2017 paper describing the Resurrection Approach shows.
Turns out we blogged about this too, almost 15 years ago, though there didn’t seem to be a Project Baseline yet at the time. I was maybe a bit hard on that press release, but more because of the misconceptions about genebanks that it revealed rather than the concept of re-collecting from the same site or population to monitor genetic change. That of course is extremely valuable, as our recent review of genetic erosion showed.

- Long-term evidence for ecological intensification as a pathway to sustainable agriculture. Meta-analysis of 30 long-term experiments from Europe and Africa comprising 25,565 data points shows that increasing crop diversity and adding fertility crops and organic matter are as good for the yield of staple crops as N fertilization, but don’t add much if you already have the latter, and vice versa.
- Revisiting the adequacy of the economic policy narrative underpinning the Green Revolution. If only the Green Revolutionaries had know the above, eh? Anyway, remember institutions, people.
- Agroecological practices increase farmers’ well-being in an agricultural growth corridor in Tanzania. Higher awareness of the benefits of nature plus more engagement with extension services mean more adoption of agroecological practices means farmers are better off. Green Revolutionaries unavailable for comment. Institutions rejoice.
- Intangible links between household livelihoods and food security in Solomon Islands: implications for rural development. Diversifying livelihoods isn’t always associated with better food security.
- Access to and Utilization of Wild Species for Food and Nutrition Security in Teso and Acholi Sub-regions of Uganda. Wait, does the above mean that decreasing access to wild foods may not necessarily matter? Why does this stuff have to be so hard?
- Climate Change and Seed System Interventions Impact on Food Security and Incomes in East Africa. More crop diversity on farms “helps farmers cope with climate change and increases productivity, food availability, incomes and food security.” Not so hard after all.
- Welfare impacts of improved groundnut varieties adoption and food security implications in the semi-arid areas of West Africa. Adopting new peanut varieties is good for farmers. Wait, so the opposite of more crop diversity? Why does this stuff have to be so hard?
- Situating Plant Genetic Resource in the K-12 Curriculum: A Critical Review. Maybe we should all go back to school.
