- A research vision for food systems in the 2020s: Defying the status quo. Research is necessary but not sufficient.
- Dismantling a dogma: the inflated significance of neutral genetic diversity in conservation genetics. Not all genetic diversity is created equal.
- A re‐evaluation of the domestication bottleneck from archaeogenomic evidence. Not so much a single bottleneck “event” on domestication, as serial bottlenecks post-domestication. Another dogma dismantled?
- Morphological and genetic diversity of Slovene lettuce landrace ‘Ljubljanska ledenka’ (Lactuca sativa L.). Not all iceberg is created equal.
- Genetic Status of the Swedish Central collection of heirloom apple cultivars. Neutral diversity is not completely useless, though?
- Understanding genetic variability in the mungbean (Vigna radiata L.) genepool. It may not be neutral variation, but it’s not associated with geography. If you see what I mean.
- A Land Evaluation Framework for Agricultural Diversification. Soil and climate data –> fancy maths –> pretty good prediction of where you find a crop.
- A unifying concept of animal breeding programs. You can describe any breeding programme by using graph theory. But would it help?
- Molecular and isotopic evidence for milk, meat, and plants in prehistoric eastern African herder food systems. Chemical and isotope analysis of lipids on ceramic shards shows early herding societies had a pretty diverse diet.
- Pre-Clovis occupation of the Americas identified by human fecal biomarkers in coprolites from Paisley Caves, Oregon. Lipids again, this time at the other end of the process, and of the world.
- Identification of novel seed longevity genes related to oxidative stress and seed coat by genome‐wide association studies and reverse genetics. Seeds need to take their antioxidants.
- Evaluation of genetic integrity of pearl millet seeds during aging by genomic-SSR markers. Loss of viability leads to loss of diversity.
- Geographical distribution of quinoa crop wild relatives in the Peruvian Andes: a participatory mapping initiative. Cultivated land is as important as more “natural” ecosystems for quinoa wild relatives.
- Global wind patterns and the vulnerability of wind-dispersed species to climate change. In the tropics, and in the lee of mountains, wind-dispersed species will find it more difficult to reach places with suitable future climates.
A maze of maps
I’ve said it before, and I’ll say it again. Maps are great. Online maps are super. But you can have too much of a good thing. Like, do we really need to have all these things spread out all over the internet?
- WRI’s Resource Watch, “a dynamic platform that leverages technology, data, and human networks to bring unprecedented transparency about the planet right now.”
- FAO’s Hand-in-Hand Geospatial Platform, “an evidence-based, country-led and country-owned initiative of the Food and Agriculture Organization of the United Nations (FAO) to accelerate agricultural transformation and sustainable rural development to eradicate poverty (SDG1) and end hunger and all forms of malnutrition (SDG2).”
- Nature Map Explorer, curated by UNEP-WCMC, which “provides a set of integrated global maps on biodiversity and ecosystems services based on the best available scientific data.”
- The Global Habitat Type Map, based on International Union for Conservation of Nature (IUCN) habitat classification scheme.
That’s just the ones that have flitted across my screen in the past few months. I’ve lost track, for example, of where CGIAR is on all this spatial data stuff. Working together is hard, I know, and exacts a cost. But would it kill them?
Meta-Brainfood for the weekend
Time to clean up a few things, I think. For a while now, I’ve been hoarding links to edited volumes. My idea was to do a special dedicated Brainfood on each one, but I now fear that just ain’t gonna happen. Too much other stuff on. So here they are. Maybe one of you will help me out? You know what to do. A pithy one or two sentences summarizing each paper, based on the abstract only if you’re into the whole brevity thing. Interested? Let me know in the comments below, and we’ll set something up. Our first guest-curated Brainfood…
Here they are:
- Do you remember the 2017 book Against The Grain: A Deep History of the Earliest States by James C. Scott? I think we may have blogged about it. Anyway, it suggested that it was grain (as opposed to tuber) cultivation that led to the development of hierarchical states. Grain is visible and portable, and so easy to tax, you see. There are interviews with the author galore if you like podcasts. Ok, well, the Cambridge Archaeological Journal had a whole Review Symposium deconstructing that particular revisionist narrative.
- In 2018, something called the 1st International Conference on Genetic Resources and Biotechnology was held in Bogor, Indonesia. A bit of a misnomer, it was really mainly about “[i]nformation system and exchanges of genetic resources for effective crop improvement.” These are the proceedings, and all of the dozens of papers are open access. Maybe someone out there could do their Top 10.
- This one is not as relevant as the others, but it’s interesting nonetheless: Remote Sensing of Plant Biodiversity. Surely some of the 20 contributions have something to say about agricultural biodiversity? Who’s willing to have a look?
- Then there’s the Special Issue of Application in Plant Sciences on Machine Learning in Plant Biology: Advances Using Herbarium Specimen Images. Yummy. Automated identification of CWR specimens, anyone?
- And finally, just out, a Topical Collection in Agriculture and Human Values on Agriculture, Food & Covid-19. Come on, who can resist a hot-take (well, a Rapid Response Opinion) entitled Maybe there is an alternative after all?
Looking forward to hearing from you.
And don’t worry, there’ll be a normal Brainfood on Monday as usual.
Switched on switchgrass
Do you live in Kentucky, Tennessee, Alabama, Mississippi, eastern Indiana, western Ohio, eastern Iowa, western North Dakota, eastern Montana, northern Wisconsin, northern Michigan, or the southern Appalachian mountains? Basically the gappy areas below.
Ok, now, do you have any switchgrass (Panicum virgatum) around where you are? Might look something like this.

If so, Dr David Lowry at Michigan State University would like to hear from you.
NOTE: In the interest of full disclosure, I had to change the photo because I uploaded the wrong species having dowloaded a number of different ones from Wikipedia. Thanks to Dave Wood for pointing that out. I originally did it in a hurry and wasn’t paying close enough attention. Sorry.
Aiming for Ames
There’s an important job opening at USDA running the Plant Introduction Station at Ames, Iowa. That’s something like 50,000 accessions to be responsible for. You can also explore the holdings of USA020, as it’s known in the trade, in Genesys. Maize is the big one, but there’s so much more there. A dream job for someone who wants to really do something to protect and use crop diversity.
