- Identification and diversity of Y‐chromosome haplotypes in Qinghai yak populations. 2 paternal lineages but weak genetic structure among the 9 populations and 3 breeds.
- Development and characterization of Triticum turgidum–Aegilops umbellulata amphidiploids. A bridge to bread wheat.
- Variation in total root length and root diameter of wild and cultivated lentil grown under drought and re-watered conditions. Some wild species have longer total root length under drought stress than crops. No word on whether bridges needed.
- The Peril of Gene-Targeted Conservation. Only warranted when said targeted genes are important for viability and have large phenotypic effects. Suspect crop breeders (see above) may beg to differ.
- Conservation of biodiversity in the genomics era. Need to target the whole genome, I guess.
- “What Matters Is Species Richness” — High School Students’ Understanding of the Components of Biodiversity. Must try harder.
- What Conservation Does. The right things, more or less, and not at all badly, so stop complaining.
- Absence of evidence for the conservation outcomes of systematic conservation planning around the globe: a systematic map. It’s not evidence of absence of conservation outcomes, but still. Maybe should get together with the above?
- East African diploid and triploid bananas: a genetic complex transported from South-East Asia. All introduced by Austronesian people, probably via Madagascar, but no longer to be found in Asia (much).
- Molecular and Cytogenetic Study of East African Highland Banana. Focuses on one of the 4 groups discussed in the above (Mutika). All derived from maybe a single hybrid clone.
- Sources of resistance to Xanthomonas campestris pv. musacearum, the causal agent of banana Xanthomonas wilt. Why bother with the above, you ask?
- Genetic diversity of day-neutral converted landrace Gossypium hirsutum L. accessions. Eastern and western hemisphere groups, with US varieties closer to the eastern.
- Crop Domestication Alters Floral Reward Chemistry With Potential Consequences for Pollinator Health. In highbush blueberry, domestication has decreased the chemical diversity of nectar and pollen, possibly increasing infection by bee gut pathogens.
- Ancient DNA analysis of Scandinavian medieval drinking horns and the horn of the last aurochs bull. Aurochs interbred with domestic cattle way back. In other news, you can extract aurochs DNA from medieval Scandinavian drinking horns.
- The USDA cucumber (Cucumis sativus L.) collection: genetic diversity, population structure, genome-wide association studies, and core collection development. Three groups, more or less: India, E. Asia, and everything else. A third of 1200 accessions recovers 96% of variation.
- Rapid improvement of domestication traits in an orphan crop by genome editing. Tomato orthologues in groundcherry mutated for more fruits and better plant architecture.
- Domestication of wild tomato is accelerated by genome editing. Or you can do it with the actual tomato genes. As suggested a couple of years ago.

- Systematic review of the effects of agricultural interventions on food security in northern Ghana. The effects are minimal in the few cases where they have been measured.
- Food and nutrient gaps in rural Northern Ghana: Does production of smallholder farming households support adoption of food-based dietary guidelines? No, especially for vegetables, so another example of the above. Also, diversity of household production positively correlated with food and nutrient coverage but neither with children’s dietary diversity and nutrient adequacy.
- Farm-Level Agricultural Biodiversity in the Peruvian Andes Is Associated with Greater Odds of Women Achieving a Minimally Diverse and Micronutrient Adequate Diet. Associated.
- Natural Variation in Wild Gossypium Species as a Tool to Broaden the Genetic Base of Cultivated Cotton. Cotton needs an infusion of diversity.
- Wild Soybeans: An Opportunistic Resource for Soybean Improvement. As above, but time is running out because the wild relatives are often weedy.
- Evolutionary trends and phylogenetic association of key morphological traits in the Italian rice varietal landscape. Again, likely shrinking, but for different reasons.
- Genetic characterization of the apple germplasm collection in Central Italy: the value of local varieties. 25 duplicates among 175 accessions from 10 collections. How many are still in orchards?
- Value of the Dutch Holstein Friesian germplasm collection to increase genetic variability and improve genetic merit. More useful to increase genetic diversity than value.

- The quinoa boom in Peru: Will land competition threaten sustainability in one of the cradles of agriculture? Looks like it.
- Recovery of a common bean landrace (Phaseolus vulgaris L.) for commercial purposes. Spain’s “Caparrona de Monzón”, to be precise. Interesting, but surely a challenge to scale up. No fear of a Caparrona Boom, I suspect.
- The Nutritional Content of Common Bean (Phaseolus vulgaris L.) Landraces in Comparison to Modern Varieties. Some are better. No word on whether the above approach will be tried on these beans in Turkey.
- Fruits of the Brazilian Atlantic Forest: allying biodiversity conservation and food security. Plinia edulis looks like it might be worth a try, Campomanesia hirsuta maybe not so much.
- Restoring to the future: Environmental, cultural, and management trade‐offs in historical versus hybrid restoration of a highly modified ecosystem. Hybrid (native + exotic plants) is better than nothing.
- Pest suppression in cultivar mixtures is influenced by neighbor‐specific plant‐plant communication. Volatiles from one barley genotype can lead to aphid suppression on neighbours of a different genotype.
