Nibbles: Insurance edition
- Biodiversity is insurance, says insurance company.
- Especially biodiversity of fruits and vegetables.
- Research by CGIAR into how best to use that insurance generates a 10:1 return on investment. Kind of. Covers breeding et al., but not genebanks. Sigh.
- Professor Claire Kremen is awarded the Volvo Environment Prize 2020 for research on how to protect that insurance while feeding the world.
- People have been fiddling with that insurance for longer than we thought, archeologists say.

- Large-scale genome-wide association study reveals that drought-induced lodging in grain sorghum is associated with plant height and traits linked to carbon remobilisation. To reduce lodging, better to select for stay-green (delayed leaf senescence) than for short stature and lodging resistance per se. Here’s a Twitter thread by one of the authors summarizing the findings.
- Green revolution ‘stumbles’ in a dry environment: Dwarf wheat with Rht genes fails to produce higher grain yield than taller plants under drought. At least it doesn’t lodge, though, right?
- A Core Subset of the ex situ Collection of S. demissum at the US Potato Genebank. From 149 to 38, keeping 96% of all marker diversity.
- Migration through a major Andean ecogeographic disruption as a driver of genotypic and phenotypic diversity in a wild tomato species. I guess if you were going to make a core collection for this you could do worse than sample ecogeographically diverse and isolated spots. Tricky to conserve in situ though.
- DNA barcoding of Oryza: conventional, specific, and super barcodes. 6 hypervariable regions in the chloroplast genome can serve as rice-specific DNA barcodes. Assuming you agree on species concepts in the first place.
- A “Global Safety Net” to reverse biodiversity loss and stabilize Earth’s climate. The 50% of the Earth to save to save the Earth.
- Three Key considerations for biodiversity conservation in multilateral agreements. Plan, model, assign responsibility.
- Mashes to Mashes, Crust to Crust. Presenting a novel microstructural marker for malting in the archaeological record. Aleurone cell breakdown in archaeobotanical remains is a robust indicator of beer-making. I bet they find it everywhere now.
- The agroecology of an early state: new results from Hattusha. Huge underground grain silos, with each container holding grain from multiple sites, which could be evidence of tax-paying. But no word on beer.
- Informal Seed Traders: The Backbone of Seed Business and African Smallholder Seed Supply. Lots of room for engagement, and considerable upside. If I were to pick out just one high-potential intervention, it would be providing training in seed testing.
- Restoring cultivated agrobiodiversity: The political ecology of knowledge networks between local peasant seed groups in France. I’m sure they’re testing their seeds.
- A Protective Role for Accumulated Dry Matter Reserves in Seeds During Desiccation: Implications for Conservation. Cells must have >35% dry matter to be able to withstand desiccation.
- Multiple lines of evidence for the origin of domesticated chili pepper, Capsicum annuum, in Mexico. It looks like we — inexplicably — missed this the first time around. Chilli, maize and beans originated in different parts of Mexico.
- Ecological intensification and diversification approaches to maintain biodiversity, ecosystem services and food production in a changing world. Though you can change one thing at a time, it’s better to redesign the whole system. But is the better the enemy of the good?
- Refining the genetic structure and relationships of European cattle breeds through meta-analysis of worldwide genomic SNP data, focusing on Italian cattle. 2 groups among Italian breeds: North-Central breeds linked to Alpine and Iberian breeds, and Podolian-Sicilian breeds with links to the Balkans.
- The Archaeology of Pig Domestication in Eurasia. Independent domestication in northern Mesopotamia by 7500 BC (extensive management) and China by 6000 BC (maybe intensive); failed to take off in Japan, for interesting reasons.
- Vegetative States: Potatoes, Affordances, and Survival Ecologies. The potato has both helped to underpin and resist state coercion. The Hittites would have worked something out, though, I feel.
- Holocene coastal evolution preceded the expansion of paddy field rice farming. Rice only moved south from the lower Yangtze 2-3000 years ago, once costal land opened up. No word on affordances.

- Projected temperature increases may require shifts in the growing season of cool-season crops and the growing locations of warm-season crops. In California’s Mediterranean climate, cool season crops will have to shift in time, and warm-season crops in place.
- A “Mega Population” of the Wild Potato Species Solanum fendleri. Large population, safe, accessible and very diverse. Who needs genebanks, right?
- Survival of Solanum jamesii Tubers at Freezing Temperatures. Very unusual trait in both the crop and the wild relatives, apparently.
- Diversity and uses of enset [Ensete ventricosum (Welw.) Cheesman] varieties in Angacha district, Southern Ethiopia: call for taxonomic identifications and conservation. 55 varieties in 75 homegardens, 88 in the field genebank, many in only one or the other.
- Impact of Climate Change on the Diversity and Distribution of Enset (Ensete ventricosum (Welw) Cheesman) in Ethiopia: A Review. Some are moving, some are dying. I guess we really need in vitro and cryo after all.
- Filling the gaps in gene banks: Collecting, characterizing and phenotyping wild banana relatives of Papua New Guinea. Much diversity of banana ancestor still not in genebanks, but people are on the job.
- Modeling the Impact of Crop Diseases on Global Food Security. Genetic diversity is not enough.
- What natural variation can teach us about resistance durability. That genetic diversity is not enough, apparently.
- Wheat blast: a new threat to food security. We have the genes to fight it, but they won’t be enough.
- Limited haplotype diversity underlies polygenic trait architecture across 70 years of wheat breeding. I hope at least those genes can be found in this MAGIC population based on European bread wheat varieties from the past few decades.
- Potential Short-Term Memory Induction as a Promising Method for Increasing Drought Tolerance in Sweetpotato Crop Wild Relatives [Ipomoea series Batatas (Choisy) D. F. Austin]. Wild sweet potatoes have the genes to remember drought stress, and hence cope with it better. Will they be enough though?
- Ecological pest control fortifies agricultural growth in Asia–Pacific economies. Biological control has been worth USD 15-20 billion a year for non-rice crops over the past 100 years across 23 countries. But how much is the interaction with genetic diversity worth?
- Evaluation of the contribution of teosinte to the improvement of agronomic, grain quality and yield traits in maize (Zea mays). Wild relative not just a source of stress resistance, could be useful for yield potential too.
- “It may also have prevented churchgoers from falling asleep”: southernwood, Artemisia abrotanum L. (fam. Asteraceae), in the church bouquet, and its contemporary presence as a heritage plant in Sweden. The fragrance lingers.
- Multiple cropping systems of the world and the potential for increasing cropping intensity. Multiple cropping on 12% of total agricultural area, which could increase, but probably not as much as was thought.
- Impact and returns on investment of mungbean research and development in Myanmar. Four varieties coming out of international research created economic gains of USD 1.4 billion from 1980-2016. That’s a ROI of about 90, but it took 20 years to kick in.
- Are Traditional Food Crops Really ‘Future Smart Foods?’ A Sustainability Perspective. Well, they could be, but maybe we don’t have 20 years.
- New Guinea highland wild dogs are the original New Guinea singing dogs. …which are therefore not extinct in the wild as used to be thought. Or so the DNA says.
- WEGE: A new metric for ranking locations for biodiversity conservation. That’s “Weighted Endemism including Global Endangerment,” and it hasn’t been tried on plants. Yet.
- Toward Unifying Global Hotspots of Wild and Domesticated Biodiversity. They overlap a lot but not completely. Expect WEGE to be applied at some stage.
