- Genetic Diversity of Bangladeshi Jackfruit (Artocarpus heterophyllus) over Time and Across Seedling Sources. Downward trend in time, but no difference between growers and nurseries.
- Plum Cultivars in Sweden: History and Conservation for Future Use. From 70 varieties in nurseries, to 45 in the genebank.
- Integration of expert knowledge in the definition of Swiss pear core collection. Let stakeholders choose a few, it won’t make too much of a difference to the overall diversity, and they’ll be pleased.
- Can agricultural intensification help to conserve biodiversity? A scenario study for the African continent. Land sparing is better for biodiversity and food production.
- Influence of experimental design on decentralized, on-farm evaluation of populations: a simulation study. Replicate populations of interest rather than controls, and environments.
- Botanicals used for cosmetic purposes by Xhosa women in the Eastern Cape, South Africa. 16 plants, 14 families, bark the most common component, skin complexion the most common use.
- Droughts, Biodiversity, and Rural Incomes in the Tropics. More access to natural biodiversity means smaller effect of drought during the growing season on income from crops.
- A global surveillance system for crop diseases. Could be extended to other threats to crop diversity?
- A data-driven approach improves food insecurity crisis prediction. Market data, rainfall, geography and demography predict food insecurity at village level in near real time.
- Rapid detection of stressed agricultural environments in Africa under climatic change 2000–2050 using agricultural resource indices and a hotspot mapping approach. Increasing trouble for Tanzania, Zimbabwe, and to a lesser extent Ethiopia. But will biodiversity, disease monitoring and food insecurity prediction help?
- Kavalactones and Flavokavins Profiles Contribute to Quality Assessment of Kava (Piper methysticum G. Forst.), the Traditional Beverage of the Pacific. High-throughput HPTLC will do the job.
- Transcriptome and organellar sequencing highlights the complex origin and diversification of allotetraploid Brassica napus. 6 genetic groups: Winter rapeseed in Europe and America, Rutabaga, Spring rapeseed, Siberian kale, Winter rapeseed in East Asia, and Winter rapeseed in Europe and South Asia. No evidence of multi-origin.
- Parallels between natural selection in the cold‐adapted crop‐wild relative Tripsacum dactyloides and artificial selection in temperate adapted maize. Artificial selection for temperate adaptation in maize involved the same genes as natural selection for temperate adaptation in Tripsacum.
Nibbles: Language erosion, Cacao genebank, Singapore genebank, Coffee fund, Insect pollination, Sustainable ag
- The link between language and biodiversity loss.
- Cacao genebank does more than conserve cacao diversity.
- Singapore gets into seed-banking. Not cacao, though.
- Sachs proposes big coffee fund to ensure sustainably. No word on genebanks, though.
- If you want to increase the cultivation of an insect-pollinated crop, you should diversify your agriculture.
- Sustainable not necessarily equal to organic.
An indicator for the conservation of socioeconomically and culturally valuable plants
The CIAT/CropTrust proposal for the calculation of “Comprehensiveness of conservation of socioeconomically as well as culturally valuable species” is up on the Biodiversity Indicators Partnership website.
Here’s a recent blog post on the indicator, which is relevant for Aichi Target 13 and SDG 2, Target 2.5.
And here’s the underlying paper which described the method in detail: Comprehensiveness of conservation of useful wild plants: An operational indicator for biodiversity and sustainable development targets.
Finally, here’s the website where you can explore the data.

- Genebank genomics bridges the gap between the conservation of crop diversity and plant breeding. What do we want? An accurate genotype-to-phenotype map for all seeds stored in the genebank. When do we want it? As soon as we have the money to ensure their conservation.
- The origins of cannabis smoking: Chemical residue evidence from the first millennium BCE in the Pamirs. Well, that’s like your opinion, man. Residues in incense burners used for mortuary rituals, if you must know.
- Patagonian berries as native food and medicine. Good, and good for you.
- Revisiting the Origin of the Octoploid Strawberry. Not 4 separate diploid progenitors, as another paper recently found, but rather 2 extant ones, once you re-do the math.
- The Nutritional Contribution of Potato Varietal Diversity in Andean Food Systems: a Case Study. It’s great, but it’s not enough.
- The origins and adaptation of European potatoes reconstructed from historical genomes. Sequencing of old herbarium specimens, including Darwin’s, shows that early introductions to Europe were from the Andes, and later admixed there with Chilean and wild material, forming a sort of secondary centre of diversity.
- Effect of Intensive Agriculture-Nutrition Education and Extension Program Adoption and Diffusion of Biofortified Crops. Breeding is not enough.
- Morphological characterisation and evaluation of cacao (Theobroma cacao L.) in Trinidad to facilitate utilisation of Trinitario cacao globally. Now we know which ones are the best, for different reasons.
- Evolution of US maize (Zea mays L.) root architectural and anatomical phenes over the past 100 years corresponds to increased tolerance of nitrogen stress. There has been unconscious selection for root traits resulting in better N use efficiency. An old paper, resurrected because of the next one.
- Breeding improves wheat productivity under contrasting agrochemical input levels. Breeding wheat in Europe for good performance under high input levels has not markedly affected its performance under more challenging conditions. Diversity has held up too.
- Positive outcomes between crop diversity and agricultural employment worldwide. Irrespective of input levels and economic growth rates.
- National food production stabilized by crop diversity. Crop diversity is not just good for rural employment (see above), but for year-on-year production stability too.
- Climate change and cultural resilience in late pre-Columbian Amazonia. And it was sort of the same in ancient Amazonia.
- Effects of Fairtrade on the livelihoods of poor rural workers. Fairtrade improves wages of workers in cooperatives, but not on small farms.

- Collecting beans in the American SW.
- Chilis too.
- Updated map of Neolithic expansion in Europe.
- The Microbiota Vault is a thing.

- Using Jerry Maguire to explain the Plant Treaty. It is not well done. But one is surprised to see it done at all.
