- The expansion of agriculture has shaped the recent evolutionary history of a specialized squash pollinator. The genetic diversity of an insect crop pollinator has been affected by the fact that it pollinates a crop.
- Native pollinators improve the quality and market value of common bean. The diversity of native insect crop pollinators affects the value of the crop they pollinate.
- A global approach for natural history museum collections. Basically amounts to “ask curators what they have.” Including presumably specimens of insect pollinators. We’ve been doing this for PGRFA for quite a while now, one way or another. Back to mainly plants next week, hopefully, but let’s keep going with animals for now, and let’s see what more we can learn.
- A 12% switch from monogastric to ruminant livestock production can reduce emissions and boost crop production for 525 million people. Ruminants are not all bad after all.
- Permafrost preservation reveals proteomic evidence for yak milk consumption in the 13th century. The Mongols thought this particular ruminant was just great.
- The self-management organization as a way for the in situ conservation of native poultry genetic resources. In response to the promotion of exotic commercial poultry breeds, women’s groups in Mexico have got together and developed rules to protect native hens. Please let not these be among the 12% of monogastrics that get replaced by yaks.
- Increasing the number of stressors reduces soil ecosystem services worldwide. It’s the number of different stressors, more than their aggregate strength, that most affects how badly soils are stressed. Goes for me too, to be honest.
- Elephants as an animal model for self-domestication. I’ll believe it when elephants domesticate yaks.

- Why can’t we predict traits from the environment? Because plants are not collections of independent, isolated traits. All the more reason to study, understand and protect wild plants of economic importance, as the following papers show.
- Differential climatic conditions drive growth of Acacia tortilis tree in its range edges in Africa and Asia. Case in point of the above. Makes germplasm evaluation really hard.
- Understanding local plant extinctions before it is too late: bridging evolutionary genomics with global ecology. Modelling based on the genomic offset (GO) method and the mutations–area relationship (MAR) can help better predict the risk of extinction of different populations.
- Crop wild relatives in Lebanon: mapping the distribution of Poaceae and Fabaceae priority taxa for conservation planning. Bekaa and Baalbak have the highest diversity and the SW the most gaps.
- Community-Level Incentive Mechanisms for the Conservation of Crop Wild Relatives: A Malawi Case Study. Paying communities to conserve crop wild relatives could work and be relatively cheap. Waiting to see this being applied in the Bekaa.
- Population genomics unravels the Holocene history of bread wheat and its relatives. Yeah but crop wild relatives really held back bread wheat domestication. So maybe the Bekaa owes everyone else.
- New insights gained from collections of wild Lactuca relatives in the gene bank of the Institute of Evolution, University of Haifa. Maybe they can gain an insight into how to make lettuce taste of something. And I wonder what environmental variable that will be associated with.
- Climate change and land-use change impacts on future availability of forage grass species for Ethiopian dairy systems. Two forages will do better under climate change, one worse. Assuming a lot of stuff.
- Application of CRISPR/Cas9 technology in forages. But plants are not collections of independent, isolated traits, right?
Nibbles: Food tree, Wild chocolate, Cacao, Cassava in Africa, Indigenous ABS, Abbasid food, Valuing trees
- Gastropod episode on The Fruit that Could Save the World. Any guesses what that might be?
- Atlas Obscura podcast on an apparently now famous wild-harvested chocolate from Bolivia. But how wild is it really?
- BBC podcast on cacao for balance.
- Forbes touts an African cassava revolution. What, no podcast?
- Very interesting piece from the ever reliable Modern Farmer on how a small seed company called Fedco Seeds designated a bunch of maize landraces as “indigenously stewarded,” and are paying 10% of what they make from the sale of their seeds to a pooled Indigenous fund which goes to support a local, multi-tribal project called Nibezun. A sort of mini-MLS? Definitely worth a podcast. Any takers?
- A long but rewarding article in New Lines Magazine describes medieval cookbooks from the Abbasid caliphate. The recipes make up for the somewhat stilted podcast.
- BGCI publication on how the Morton Arboretum works out whether it should be growing a particular population or species of tree. The trick is to quantify 5 types of “value”: environmental, evolutionary, genetic diversity, horticultural, conservation. Though one could also consider hostorical/cultural, educational and economic value as well. I suspect in the end it comes down to whether it looks nice in an available gap. If I were to do a podcast on this, I’d test it out with the tree in the first of these Nibbles.

- Palaeogenomics of Upper Palaeolithic to Neolithic European hunter-gatherers. Farmers may have pushed hunter-gatherers to the northern edge of Europe while also in mixing with them.
- Identification and exploitation of wild rye (Secale spp.) during the early Neolithic in the Middle Euphrates valley. Those Europeans on the move — both farmers and hunter-gatherers — would have been familiar with wild rye, but that’s pretty much gone from the Fertile Crescent now.
- Caribbean Deep-Time Culinary Worlds Revealed by Ancient Food Starches: Beyond the Dominant Narratives. But enough about Europe. It wasn’t always all about cassava in the pre-colonial, and indeed colonial, Caribbean…
- Reuniting the Three Sisters: collaborative science with Native growers to improve soil and community health. …as there was also the maize/beans/squash system in that part of the world, and may well be again.
- Understanding Early Modern Beer: An Interdisciplinary Case-Study. Something else that could come back is early modern Irish beer, and I’d be there for that.
- Forgotten forest relics: Apple trees (Malus spp.) in eastern U.S. forests. Old abandoned orchards, and escapes therefrom, could have lots of interesting apple diversity. Early modern American cider, anyone?
- Building a feral future: Open questions in crop ferality. And it’s not just apples. It’s a whole movement in fact.
- Resynthesized Rapeseed (Brassica napus): Breeding and Genomics. Sure, we can rebuild it, we have the technology. But will it go feral on us again?
Brainfood: Genomics for conservation and use edition
- How genomics can help biodiversity conservation. Let’s find out, but let’s broaden it to use as well, shall we? On the assumption that what’s good for conservation is good for use, and vice versa.

- Honey bee populations of the USA display restrictions in their mtDNA haplotype diversity. Yeah, you guessed it, pollinators too.
- Mezcal worm in a bottle: DNA evidence suggests a single moth species. I rest my case.
