- Conservation prioritization can resolve the flagship species conundrum. Focusing on 500-odd charismatic mammals, birds and reptiles can account for 80-90% of the species that can be covered in an optimization not constrained by such flagships. But how many CWR? Or, looking at it from the other side, what if CWR were the flagships? Yeah, right, right?
- Spatiotemporal trends in adequacy of dietary nutrient production and food sources. Global production can provide everyone with all nutrients except vitamin A, but 120 countries are not self-sufficient. Another way we’re all interdependent. But at least we have trade. Right?
- First adaptation of quinoa in the Bhutanese mountain agriculture systems. Someone mention interdependence?
- Phenotypic Variation in Leaf Morphology of the USDA, ARS Sweetpotato (Ipomoea batatas) Germplasm Collection. Everything is Normal.
- Characterization of Globally Important Agricultural Heritage Systems (GIAHS) in Europe. They’re ok but there could be more.

- Assessment of Genetic Diversity of the “Acquaviva Red Onion” (Allium cepa L.) Apulian Landrace. It’s a well-defined variety that is noticeably sweeter than others.

- Acquisition and regeneration of Spinacia turkestanica Iljin and S. tetrandra Steven ex M. Bieb. to improve a spinach gene bank collection. CGN plugs some gaps.
- Recent responses to climate change reveal the drivers of species extinction and survival. Niche shifts more important than dispersal in avoiding extinction.
- Climate change responses benefit from a global food system approach. Well I never.

- The environmental impacts of palm oil and its alternatives. Not as bad as you may think.
- Macroalgal germplasm banking for conservation, food security, and industry. Liquid cultures in dormancy is the way to do it, apparently.
- Simple Sequence Repeat-Based Genetic Diversity and Analysis of Molecular Variance among on-Farm Native Potato Landraces from the Influence Zone of Camisea Gas Project, Northern Ayacucho, Peru. So what will be done about it?
- Livelihood, Food and Nutrition Security in Southern Africa: What Role Do Indigenous Cattle Genetic Resources Play? A big role which in in danger and could in fact be bigger.
- 5,200-year-old cereal grains from the eastern Altai Mountains redate the trans-Eurasian crop exchange. Wheat and barley in the Altai one thousand years before we thought.
- Complex responses of global insect pests to climate warming. 41% of 31 globally important phytophagous insect pests will increase in severity, jury out on what will happen with the others.

- Economic benefits from plant species diversity in intensively managed grasslands. More species means more milk, more money and less risk.
- Community structure of soil fungi in a novel perennial crop monoculture, annual agriculture, and native prairie reconstruction. Perennial monoculture not unlike native prairie.
- Origins and insights into the historic Judean date palm based on genetic analysis of germinated ancient seeds and morphometric studies. Ancient Judean dates may have come from further east.
- Genetic diversity and traditional uses of aboriginal grape (Vitis vinifera L.) varieties from the main viticultural regions of Armenia. 71 genotypes, no less.

- Genomics of sorghum local adaptation to a parasitic plant. Why we need on-farm conservation.
- Mapping patterns of abiotic and biotic stress resilience uncovers conservation gaps and breeding potential of Vigna wild relatives. Sources of resistance to biotic stresses are more common than to abiotic stresses, in terms of the number of species that have them.
- Archaeobotanical evidence of food plants in Northern Italy during the Roman period. Nice take-homes from Dr Lisa Lodwick on Twitter.
- The environmental consequences of climate-driven agricultural frontiers. Areas newly suitable for one or more crops store a lot of C, cover a lot of important watersheds and are home to a lot of biodiversity.
