- Archaeological expansions in tropical South America during the late Holocene: Assessing the role of demic diffusion. Some agricultural diffusion in lowland South America was the movement of ideas rather than people.
- The origins of Amazonian landscapes: Plant cultivation, domestication and the spread of food production in tropical South America. Where did the farming people and/or ideas move from? The sub-Andean montane forest of NW South America and the shrub savannahs and seasonal forests of SW Amazonia.

- Agricultural Food Production Diversity and Dietary Diversity among Female Small Holder Farmers in a Region of the Ecuadorian Andes Experiencing Nutrition Transition. Higher diversity of crops on family farms is only weakly associated with greater dietary diversity and lower household food insecurity among female caretakers. Better than nothing, though, right?
- Productive Capacity of Biodiversity: Crop Diversity and Permanent Grasslands in Northwestern France. Having a bigger percentage of permanent grassland on your French farm, or a greater diversity of crops, can increase cereal and milk yields. No word on diets.
- The influence of landscape composition and configuration on crop yield resilience. No effect on yield per se (see above), but proximity to semi-natural habitat does increase yield stability in UK farms.
- Living off the land: Terrestrial-based diet and dairying in the farming communities of the Neolithic Balkans. Ancient farmers had a varied diet, but possibly not involving consumption of raw milk, at least by adults.
- Food securers or invasive aliens? Trends and consequences of non-native livestock introgression in developing countries. In 40 countries, the proportion of livestock populations belonging to local breeds has been decreasing by about 1% a year for the past 20 years. Hey, but milk yield per cow has been going up, so there’s that.
- Potentials of Cultivated Varieties and Wild Yam Seeds as Efficient Alternative Plant Genetic Resources for Resistant Genotypes against Yam Mosaic Virus (YMV) in Togo. Work with seeds! But were they properly inoculated? Hopefully a virologist will tell us.
- Genome-wide association analysis reveals new insights into the genetic architecture of defensive, agro-morphological and quality-related traits in cassava. Lots of interesting markers for cassava breeders, or at least those working with material from W Africa. Do it for yams next?
- High-resolution satellite imagery applications in crop phenotyping: An overview. Clouds, you say? Not a problem any more. But can it distinguish landraces from modern varieties? What’s needed is a sort of mutant algorithm, I guess.
- Crop type identification and spatial mapping using Sentinel-2 satellite data with focus on field-level information. Still some way from being able to distinguish landraces from modern varieties, I see.
- Global forest restoration and the importance of prioritizing local communities. I’m shocked I tell you, shocked.
- Protection gaps and restoration opportunities for primary forests in Europe. A lot of restoration could usefully be done in currently protected areas, though it would be better if these were expanded. No word on local communities.
- Mapping the forest disturbance regimes of Europe. I guess this means that restoration, when it happens, will be monitored from space.
- Genetic rescue: A critique of the evidence supports maximizing genetic diversity rather than minimizing the introduction of putatively harmful genetic variation. When you do do restoration, don’t worry about genetic pollution, just go for as much diversity as possible. Well, for small relict populations. Of animals.
- Considerations for large-scale implementation of dormant budwood cryopreservation. It’s about the logistics.
- Development of a fast and user-friendly cryopreservation protocol for sweet potato genetic resources. It’s the axillary meristems. Among other things.
- The human–environment nexus and vegetation–rainfall sensitivity in tropical drylands. Dryland grasslands in Africa and Asia less able to respond to water availability overall, more able in Australia and S America, evens stevens in N America. Would be interesting to mash up particularly hard-hit areas with CWR and forage germplasm collecting localities.

- 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.

- 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?

- 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.
