- And we’re back: Desertification threatening Mongolia. Will Biden talk about that on his 6-hour visit today? No, I don’t think so either. Fortunately some people are trying to do something.
- Life not great for pastoralists in Kenya either. But some people are looking to camel milk to see them through. Alas, the latest effort to boost food security research in E. Africa doesn’t have much for livestock-keepers.
- Kew tries to reform UK native grassland seed business. Hope they are taking latest figures on species migration speeds into account.

Brainfood: Barley genes, Stability & Diversity, Access & Benefit Sharing,
- Analysis of >1000 single nucleotide polymorphisms in geographically matched samples of landrace and wild barley indicates secondary contact and chromosome-level differences in diversity around domestication genes. They’ve been exchanging genes! Oh, and the site of domestication may be further south.
- Identifying population- and community-level mechanisms of diversity–stability relationships in experimental grasslands. Stability depends on a few dominant species that are out of sync with one another.

Old specimen is new melon crop wild relative
Taxonomy is not the most glamorous of subjects. Taxonomists who venture to suggest that well-loved Latin names might be changed to reflect new knowledge are roundly denounced. Prefer Latin names over “common” names and you are considered a bit of a dork. But taxonomy matters, becuse only if we know we use the same name for the same thing do we know that we are indeed talking about one thing and not two. And that can have important consequences, not least for plant breeding.
A new paper takes a close look at some old herbarium specimens, originally collected in 1856 by Ferdinand von Mueller. 1 Mueller was born in Germany in 1825 and went to Australia in 1845, for his health. There, in addition to being a geographer and physician, he became a prominent botanist. He collected extensively, including a long expedition to northern Australia in 1855-6. There he collected many specimens that turned out to be new to science, including two new melons that he called Cucumis jucundus and C. picrocarpus. The two of them are preserved on this herbarium sheet at Kew.
Fast forward 160 years or so, past a few older taxonomic revisions, and you get to one based on molecular analysis that splits the two previously recognized species of Cucumis in Asia, the Malesian region and Australia into 25 species. By this analysis Australia harbours seven species of Cucumis, five of them new to science. C. picrocarpus is one of the two previously recognized species, and the molecular analysis reveals that it is actually the closest wild relative of the cultivated melon, C. melo.
So what? Quite apart from the necessity to call things by their correct names, cultivated melons are besieged by many economically important pests and diseases. It seems likely that, as so often, resistance will come from a wild relative. Which means it is good to know exactly which plant is the closest wild relative. So what’s the status of C. picrocarpus in the wild? I have no idea, alas. I couldn’t find any entries in GBIF (possibly because they are all subsumed under C. melo) and with Luigi gone temporarily to ground I’m not sure where else to look. It seems a fair bet that it might need protection, although I’d be delighted to be wrong.
