- ‘White gold’ guano fertilizer drove agricultural intensification in the Atacama Desert from ad 1000. And maize was at the heart of it.
- What’s new during the first millennium BCE in Greece? Archaeobotanical results from Olynthos and Sikyon. Not maize, alas, but what you’d expect, plus pine and sesame.
- Local adaptation contributes to gene expression divergence in maize. Stress-response genes are the ones which have been selected. No word on whether any of them were important in the Atacama.
- Genotyping tools and resources to assess peanut germplasm: smut-resistant landraces as a case study. Ok, so it sounds like the resistant line that was previously used is virtually identical to an accession in the USDA collection.
- Do We Need to Identify Adaptive Genetic Variation When Prioritizing Populations for Conservation? No, but we’ll need it to prioritize use, surely?
- Incorporating Realistic Trait Physiology into Crop Growth Models to Support Genetic Improvement. We’ll need better growth models too.
- Wild to domesticates: genomes of edible diploid bananas hold traces of several undefined genepools. 3 of them, in fact, in both SE Asia and New Guinea.
- Evolution of the bread wheat D-subgenome and enriching it with diversity from Aegilops tauschii. Three lineages were involved in the hybridizations that led to bread wheat. Coincidence?
- De novo genome assembly of two tomato ancestors, Solanum pimpinellifolium and Solanum lycopersicum var. cerasiforme, by long-read sequencing. Thousands of genes not found in the cultivated crop, apparently.
- Genomic mechanisms of climate adaptation in polyploid bioenergy switchgrass. Introgression from the northern genepool (one of three) was really important in adaptation after the glaciers retreated. Gene duplication also involved in adaptation.
- Economic Studies Reinforce Efforts to Safeguard Specialty Crops in the United States. Where “safeguard” means “provide clean planting material.”
- Comparative analysis of genetic diversity of rice (Oryza sativa L.) varieties cultivated in different periods in China. Diversity went up, then down, between the 1980s and the 2010s.
- Wheat Varietal Diversification Increases Ethiopian Smallholders’ Food Security: Evidence from a Participatory Development Initiative. Why the diversity in breeding programmes is important, and how farmer participation can help maintain it.
- The tricot citizen science approach applied to on-farm variety evaluation: methodological progress and perspectives. How to do the above.
- Biodiversity and conservation of Phoenix canariensis: a review. A wild relative in trouble, and what to do about it.
- Tropical and Mediterranean biodiversity is disproportionately sensitive to land-use and climate change. As can be seen from the above.

- No buzz for bees: Media coverage of pollinator decline. Nobody cares. Unless it’s linked to climate change.
- Climate impacts associated with reduced diet diversity in children across nineteen countries. Something else that’s linked to climate change and too few care about.
- People are essential to linking biodiversity data. Seriously, get an ORCID ID.
- Why European biodiversity reporting is not reliable. It’s the free indicator choice in CBD reporting is what it is. Also, not enough attention to genetic diversity. Now, where have I heard that before?
- Reversing extinction trends: new uses of (old) herbarium specimens to accelerate conservation action on threatened species. Not just useful in generating new knowledge (including on genetic diversity), can also be used as seed sources and in public awareness.
- Ex Ante Assessment of Returns on Research Investments to Address the Impact of Fusarium Wilt Tropical Race 4 on Global Banana Production. Conventional breeding for resistance could lift almost a million people out of poverty. That would be quite the indicator.
- Genomic resources in plant breeding for sustainable agriculture. Would help with the above.
- Can Niche Markets for Local Cacao Varieties Benefit Smallholders in Peru and Mexico? Maybe. Read it, it’s not that long.
- Quantifying and addressing the prevalence and bias of study designs in the environmental and social sciences. Everyone should use randomised designs and controlled observational designs with pre-intervention sampling. No, you did not just waste your time reading the above.
- Crop wild relatives of the United States require urgent conservation action. 60% of 600 native taxa need urgent help.
- Limits and constraints to crop domestication. Most of the world’s 2000 crops are not fully domesticated, for reasons such as trait architecture, lack of diversity in domestication traits, accumulation of genetic load and gene flow from the above. But something can be done about it.
