- Genetic structure of the Canarian palm tree (Phoenix canariensis) at the island scale: does the “island within islands” concept apply to species with high colonization abilities? High dispersal ability doesn’t always lead to high connectivity among populations.
- Uncertainties of potentials and recent changes in global yields of major crops resulting from census- and satellite-based yield datasets at multiple resolutions. Average overall annual yield increases of about 1.5% for maize, rice, wheat and soybean for 1981 to 2008 are uncertain and probably not sufficient.
- Indigenous underutilized vegetables for food and nutritional security in an island ecosystem. People in the the Andaman and Nicobar Islands eat a lot of different vegetables. Interestingly, most are perennial and a quarter are wild.
- Knowledge Loss and Change Between 2002 and 2017—a Revisit of Plant Use of the Maasai of Sekenani Valley, Maasai Mara, Kenya. But for how long will the above be true?
- Use of grass seed resources c.31 ka by modern humans at the Haua Fteah cave, northeast Libya. Including wild wheat relative(s).
- Soybean PI 675847 A as a new source of salt tolerance. But it can’t be the only one, surely?
- The carob tree at the crossroad of domestication center and refugia hypotheses. Out of the west, surprisingly.
- Pesticidal Plant Extracts Improve Yield and Reduce Insect Pests on Legume Crops Without Harming Beneficial Arthropods. Worth a try.
- Genome-wide selection footprints and deleterious variations in young Asian allotetraploid rapeseed. Asian rapeseed derived from European, diverged, introgressed, split into 2 groups.
- Essential amino acids: master regulators of nutrition and environmental footprint? If you take essential amino acids into account, livestock production doesn’t seem such a bad idea after all.
- Parallel selection on a dormancy gene during domestication of crops from multiple families. Cloned soybean dormancy gene also showed evidence of selection during domestication in rice and tomato.
- Two Likely Auto-Tetraploidization Events Shaped Kiwifruit Genome and Contributed to Establishment of the Actinidiaceae Family. And you can thank them for the high vitamin C content.
- Hydraulic diversity of forests regulates ecosystem resilience during drought. More diverse forests better at coping with dry spells.

- Lawrence Haddad on how to start transforming the food system.
- Here’s an idea: CIMMYT genebank recognized for restoring agricultural diversity in Guatemala.
- And another. Cash transfers are better than more conventional interventions for malnutrition, but they have to be real money.
- But, of course, they don’t always work. That’s one of many development myths listed in this fun Twitter thread.
- We also need metrics, sure, but the right ones, and we may already have them.
- The first ecologist remembered. That would be Humboldt.
- Terrible visualizations of the changing geography of American agriculture.
- But where are heirloom grown? Rice, say?
- And where are all the pomegranate farmers?
- I’m sure there are plenty of grape maps of France somewhere. But what’s with all these varieties? And are there more than in pomegranate?
- IUCN launches a new Red List website.
- Laos launches a sort of Red List website on traditional foods. Here it is. No word on linkages with Ark of Taste.
- Belgian lambic beer threatened by climate change. Now it’s personal.
- In Italy, the landscape needs people to keep it safe.
- Even olive landscapes, which maybe need to be more promiscuous.
- Early agricultural migrations fuelled by cheese.
- Early eggplant migrations fuelled by elephants.
- Microbes to the rescue.

- How Do Young Adults Engage With Science and Research on Social Media? Some Preliminary Findings and an Agenda for Future Research. Facebook, not Twitter. So I’m doing it all wrong? Any young adults reading this and want to tell me how I’m doing?
- Genetic dissection of grain zinc concentration in spring wheat for mainstreaming biofortification in CIMMYT wheat breeding. Two interesting regions on different chromosomes.
- Harnessing genetic potential of wheat germplasm banks through impact-oriented-prebreeding for future food and nutritional security. Not just Zn.
- Genetic analysis of a major international collection of cultivated apple varieties reveals previously unknown historic heteroploid and inbred relationships. The deep history of the justly famous UK collection.
- Middle-range theories of land system change. Towards a Grand Unified Theory. But do we need one?
- Classifying drivers of global forest loss. Commodities, basically. But what’s the good of that without a theory?
- The environmental costs and benefits of high-yield farming. Theory shtheory: measure externalities.
- Beyond Calories: A Holistic Assessment of the Global Food System. Micronutrients get lost disproportionately badly along the supply chain. How’s that for a theory?
Nibbles: Farm subsidies, Pressing and naming plants, Cowpea primer, California crop maps, Caribbean mangoes, ABS meeting, Banana mapping, Sarada Krishnan, Indian millets, Apple varieties, Early modern bees
- Fun Twitter thread on zombie tropes about farm subsidies in the US. Should have been a blog post, though.
- Kew boffins on how to make an herbarium specimen. More complicated than you might think. And why it’s important. While I’m at it, this is how you use herbarium specimens etc. to name plants.
- IITA genebank manager interviewed about cowpea.
- Everything you ever wanted to know about the history of cartography. Not very relevant here, I know, but a monumental achievement that I wanted to celebrate. And here’s a wonderful example of cutting-edge online cartography that will no doubt feature in a future edition.
- The banana mapping project is progressing nicely.
- Damn, I missed the St Lucia mango festival. Next year?
- Africa discusses ABS.
- Dr Sarada Krishnan of Denver Botanic Garden profiled. She worked on the global coffee conservation strategy. Among many other things.
- Millets to the rescue in Gujarat.
- Red Delicious bumped from top apple spot.
- Amateurs have spread information about beekeeping since 16th century.
R you interested in species distribution models?
If you always wanted to do species distribution modelling, it’s your lucky day. Let Robert Hijmans and Jane Elith take you by the hand.
This document provides an introduction to species distribution modeling with R. Species distribution modeling (SDM) is also known under other names including climate envelope-modeling, habitat modeling, and (environmental or ecological) niche-modeling. The aim of SDM is to estimate the similarity of the conditions at any site to the conditions at the locations of known occurrence (and perhaps of non-occurrence) of a phenomenon. A common application of this method is to predict species ranges with climate data as predictors.
