- Recent land use and management changes decouple the adaptation of livestock diversity to the environment. The diversity of traditional livestock breeds used to be closely related to climate in Spain, but this is breaking down.
- Rationalizing ex situ collection of reproductive materials for endangered livestock breed conservation. Also in Spain, so I hope these guys are talking to the above.
- Applying the zoo model to conservation of threatened exceptional plant species. Not to mention livestock in Spain? Basically talking about a pedigree-based approach.
- Selection and drift reduce genetic variation for milk yield in Manech Tête Rousse dairy sheep. A bit like this (see above)?
- Influence of land tenure interventions on human well-being and environmental outcomes. Fairly good evidence from meta-review that formal titling has good social and environmental outcomes. But what did it do for traditional breeds, right?
- Lipid residues in pottery from the Indus Civilisation in northwest India. Not as much dairy as thought, and mainly non-ruminant fats. Definitely traditional breeds though.
- Ancient proteins provide evidence of dairy consumption in eastern Africa. Starting when lactase persistence was still rare or absent.
- Genome-scale sequencing and analysis of human, wolf and bison DNA from 25,000 year-old sediment. Sediment? Yep, sediment.
- Effect of dry heat on seed germination of Desmodium and Stylosanthes species. Could be used rather than mechanical scarification, thus saving time and effort. Livestock gotta eat.

Tweeting beans
Twitter is often a hellsite, but every once in a while, it really comes through. Case in point is this cool summary of a recent paper on the genetics and physiology of seed dormancy in common beans posted by one of the authors, Dr David Lowry.

Now, I know some of you are not going to want to click on the above, so here it is in ThreadReader. And if you just want the bottom line…
What have genebanks done for us lately?
Quick alert for a couple of special issues of journals dealing with crop diversity issues:
- Food Security: genebank impacts. More info on the Genebanks Platform website.
- Crop Science: pre-breeding using crop wild relatives. Blog post from the Crop Trust website.
There should be more blog posts coming out soon on a number of these papers, and you can keep track on the Crop Trust Twitter feed.
