- Agricultural Food Production Diversity and Dietary Diversity among Female Small Holder Farmers in a Region of the Ecuadorian Andes Experiencing Nutrition Transition. Higher diversity of crops on family farms is only weakly associated with greater dietary diversity and lower household food insecurity among female caretakers. Better than nothing, though, right?
- Productive Capacity of Biodiversity: Crop Diversity and Permanent Grasslands in Northwestern France. Having a bigger percentage of permanent grassland on your French farm, or a greater diversity of crops, can increase cereal and milk yields. No word on diets.
- The influence of landscape composition and configuration on crop yield resilience. No effect on yield per se (see above), but proximity to semi-natural habitat does increase yield stability in UK farms.
- Living off the land: Terrestrial-based diet and dairying in the farming communities of the Neolithic Balkans. Ancient farmers had a varied diet, but possibly not involving consumption of raw milk, at least by adults.
- Food securers or invasive aliens? Trends and consequences of non-native livestock introgression in developing countries. In 40 countries, the proportion of livestock populations belonging to local breeds has been decreasing by about 1% a year for the past 20 years. Hey, but milk yield per cow has been going up, so there’s that.
- Potentials of Cultivated Varieties and Wild Yam Seeds as Efficient Alternative Plant Genetic Resources for Resistant Genotypes against Yam Mosaic Virus (YMV) in Togo. Work with seeds! But were they properly inoculated? Hopefully a virologist will tell us.
- Genome-wide association analysis reveals new insights into the genetic architecture of defensive, agro-morphological and quality-related traits in cassava. Lots of interesting markers for cassava breeders, or at least those working with material from W Africa. Do it for yams next?
- High-resolution satellite imagery applications in crop phenotyping: An overview. Clouds, you say? Not a problem any more. But can it distinguish landraces from modern varieties? What’s needed is a sort of mutant algorithm, I guess.
- Crop type identification and spatial mapping using Sentinel-2 satellite data with focus on field-level information. Still some way from being able to distinguish landraces from modern varieties, I see.
- Global forest restoration and the importance of prioritizing local communities. I’m shocked I tell you, shocked.
- Protection gaps and restoration opportunities for primary forests in Europe. A lot of restoration could usefully be done in currently protected areas, though it would be better if these were expanded. No word on local communities.
- Mapping the forest disturbance regimes of Europe. I guess this means that restoration, when it happens, will be monitored from space.
- Genetic rescue: A critique of the evidence supports maximizing genetic diversity rather than minimizing the introduction of putatively harmful genetic variation. When you do do restoration, don’t worry about genetic pollution, just go for as much diversity as possible. Well, for small relict populations. Of animals.
- Considerations for large-scale implementation of dormant budwood cryopreservation. It’s about the logistics.
- Development of a fast and user-friendly cryopreservation protocol for sweet potato genetic resources. It’s the axillary meristems. Among other things.
- The human–environment nexus and vegetation–rainfall sensitivity in tropical drylands. Dryland grasslands in Africa and Asia less able to respond to water availability overall, more able in Australia and S America, evens stevens in N America. Would be interesting to mash up particularly hard-hit areas with CWR and forage germplasm collecting localities.
- Botanic garden solutions to the plant extinction crisis. Expertise, tools, facilities, and networks are there. You know what’s missing, right?
Brainfood: Bending the curve edition
- Bending the curve of terrestrial biodiversity needs an integrated strategy. Meaning: (i) sustainable agricultural intensification, (ii) trade, (iii) less food waste, (iv) more plant-based human diets, and (v) more and better protected areas.
- The carbon opportunity cost of animal-sourced food production on land. See (iv) above.
- Just ten percent of the global terrestrial protected area network is structurally connected via intact land. See (v) above.
- Cropland expansion in the United States produces marginal yields at high costs to wildlife. See (i) above.
- A cultivated planet in 2010 – Part 1: The global synergy cropland map. Gotta know where the cropland is before you can do (i) above.
- Advances in plant phenomics: From data and algorithms to biological insights. Fancy maths can really help with (i) above.
- Retrospective Quantitative Genetic Analysis and Genomic Prediction of Global Wheat Yields. Different fancy maths shows that CIMMYT’s Obregon wheat testing site can really help with (i) above.
- Diversity analysis of 80,000 wheat accessions reveals consequences and opportunities of selection footprints. Here’s some stuff that wheat breeders can use to develop new materials to test at Obregon using phenomics, genomics and fancy maths.
- First report on cryopreservation of mature shoot tips of two avocado (Persea americana Mill.) rootstocks. This should help with (iv) above. Eventually, work with me here.
- Bread and porridge at Early Neolithic Göbekli Tepe: A new method to recognize products of cereal processing using quantitative functional analyses on grinding stones. Ahem. Well… No, sorry, I got nothing.
Nibbles: Rematriation, Tanzanian bananas, Persea cryo, Urbanization
- Seeds going home, thanks to the Indigenous Seed Keepers Network and others.
- Matooke gets its first hybrids.
- Avocado gets its first solid cryo protocol.
- The agricultural challenges and opportunities of African urbanization. No word on the fact that more and more ag will be urban ag. Or on what it will all mean for crop diversity.
Welcome to the world, Kurt
What can you do about inbreeding in a small population of a species that nearly went extinct? Well, if the species is Przewalski’s horse, one thing you can do is inject some new diversity into the genepool by cloning a genetically very distinct stallion whose cells you happened to put in liquid nitrogen forty years ago. The whole amazing story is on the website of the Revive & Restore project.
This is huge. The first cloning for conservation.
It's a male Przewalski's horse ("shuh-VAL-ski") from 40 years ago, now revived to help enrich the genomes of the whole wild population.

The new foal’s name is Kurt. Why?
Kurt is named in honor of Dr. Kurt Benirshke, a geneticist at the San Diego Zoo who in 1975 had a prescient idea. Dr. Benirshke began what is now the Frozen Zoo, collecting and cryopreserving the cell lines of endangered species and safely storing away genetic diversity before it was lost. At the time the collection was a bet on cloning and reproductive technologies that did not yet exist. Nearly fifty years later, with the partnership of San Diego Zoo Global Frozen Zoo, Revive & Restore, and ViaGen Pets and Equine, Dr. Benirschke’s plans are quite literally coming to life.

Nibbles: Horse cloning, Fish genes, Breeding manuals, Capsicum podcast
- Boffins clone Przewalski’s horse.
- Boffins start fish genebank. Cloning next?
- Boffins deconstruct the breeders’ equation. Apply to fish next?
- Boffin (and Jeremy) discusses how the chilli pepper got to China. Goes well with fish. The pepper, not the podcast.
