- Ten golden rules for reforestation to optimize carbon sequestration, biodiversity recovery and livelihood benefits. Right seeds, right species, right place, the right way. But save forests first.
- The impact of near-real-time deforestation alerts across the tropics. Getting alerts saves forests, especially in protected areas, but only in Africa.
- Integration of georeferenced and genetic data for the management of biodiversity in sheep genetic resources in Brazil. Travel 300 km for a genetically different sheep. I wonder if it’s the same for trees.
- Worldwide occurrence records suggest a global decline in bee species richness. 25% fewer species in GBIF in past 25 years. Yeah but there may be alternative explanations for that, as a bee taxonomist points out. Non-Twitter link available too.
- Investigating genetic relationship of Brassica juncea with B. nigra via virtual allopolyploidy and hexaploidy strategy. Wild relative could be used to synthesize some really cool mustards.

Brainfood: Livestock edition
- 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.

- Large‐scale genome‐wide association study, using historical data, identifies conserved genetic architecture of cyanogenic glucoside content in cassava (Manihot esculenta Crantz) root. Two loci explain about a third of variation in HCN content.
- Strategic use of Iranian bread wheat landrace accessions for genetic improvement: Core set formulation and validation. Not much structure, but some accessions are good for multiple traits.
- Population studies of the wild tomato species Solanum chilense reveal geographically structured major gene-mediated pathogen resistance. Not all populations of a crop wild relatives will be equally useful in breeding.
- Genetic diversity of Ethiopian sorghum reveals signatures of climatic adaptation. 12 sub-populations, with about 10% of the variation explained by either agroecology or geography.
- Common bean SNP alleles and candidate genes affecting photosynthesis under contrasting water regimes. And all in just 158 Portuguese accessions.
- Genetic Diversity and Population Structure of Algerian Endemic Plant Species Avena macrostachya Bal. ex Cross. et Durieu. Collecting sites need to be visited again. I can vouch that doing so would be very interesting.
- Conservation priorities for African Vigna species: Unveiling Angola’s diversity hotspots. It’s a huge collecting gap.
- Remote sensing enabled essential biodiversity variables for biodiversity assessment and monitoring: technological advancement and potentials. The Remote Sensing enabled Essential Biodiversity Variables are a work in progress. Would like to see it applied to those Vignas.
- Genomic consequences of apple improvement. …are relative genetic uniformity.

- Exotic foods reveal contact between South Asia and the Near East during the second millennium BCE. Bronze Age Levantines ate bananas and soya, according to dental calculus. No word on coffee.
- Archaeological Central American maize genomes suggest ancient gene flow from South America. Pre-domesticated maize was taken to South America, where is was finished off away from introgression from pesky wild relatives, and then taken back home.
- Fruits of the Veld: Ecological and Socioeconomic Patterns of Natural Resource Use across South Africa. South Africans collect and eat a lot of wild fruits, but could plant and eat them more.
- Exploring the Biodiversity of Red Yeasts for In Vitro and In Vivo Phenotypes Relevant to Agri-Food-Related Processes. Which is interesting because they can delay food spoilage and also provide nutritional supplements. Though personally I’d prefer veld fruits.

- Effective population size remains a suitable, pragmatic indicator of genetic diversity for all species, including forest trees. Which is good because you can estimate it fairly easily. Well, kinda. It’s important because it’s one of the Genetic diversity targets and indicators proposed for the CBD post-2020 Global Biodiversity Framework.
