- Livestock grazing boosts plant diversity in the Greater Serengeti–Mara Ecosystem. Livestock can be good for biodiversity conservation. But can its diversity be conserved too? Let’s see.
- Conservation and Management of Animal Genetic Resources in the Context of African Livestock Production Systems: The Case for In Situ and Ex Situ Conservation. “The multi-stakeholder breeders-researchers-decision-makers approach remains the most robust solution for sound management and preservation of biological units.” What, no farmers and local communities? No, that’s unfair: community-based conservation is discussed. But it doesn’t feel as central to the whole thing as it should be, somehow.
- Genetic Diversity, Adaptation, Wild Introgression, and Coat Color Mutation of Golden Yak. After all, local communities have maintained the golden yak reasonably well.
- Caprine dairy exploitation on the Iranian Plateau from the seventh millennium BC. Not to mention goats in Iran, and for thousands of years…
- Old goats: 3,000 years of genetic connectivity of the domestic goat in Ireland. …and in Ireland, though for not quite as long, admittedly.
- Dogs were widely distributed across western Eurasia during the Palaeolithic. And local communities have been managing dog populations since way before farming even.
- The dispersal of domestic cats from North Africa to Europe around 2000 years ago. Also, local communities managed early cats separately in the Levant and Egypt. Much later than dogs, but that’s cats for you.
- A microbiome catalog of Chinese traditional artisanal cheeses provides insights into functional and microbial diversity. And don’t forget to conserve the associated microbiome too. I wonder what golden yak cheese is like.
Brainfood: History edition
- Phylogenetics and evolution of Digitaria grasses, including cereal crops fonio, raishan and Polish millet. The history of wild Digitaria goes back 2–6 million years.
- Biogeography of Crop Progenitors and Wild Plant Resources in the Terminal Pleistocene and Early Holocene of West Asia, 14.7–8.3 ka. This is what the distribution of crop wild relatives looked like in West Asia 10 thousand years ago or thereabouts. No Digitaria, but plenty of other stuff.
- Ancient use and long-distance transport of the Four Corners Potato (Solanum jamesii) across the Colorado Plateau: Implications for early stages of domestication. At roughly the same time, a couple continents and an ocean over, a local potato species was being processed outside its rage. Was it cultivated? Do the math.
- State formation across cultures and the role of grain, intensive agriculture, taxation and writing. And a few thousand years later, there were domesticated grains, states, and taxes. In that order. Do the math.
- The Archaeology of Olive Oil Production in Roman and Pre-Roman Italy. Pretty sure the Romans had a state and taxes. They also had domesticated olives.
- Wines of Fire and Earth: Exploring the Volcanic Terroirs of the Canary Islands – a Case Study. No Romans on the Canaries, but plenty of vines.
- Black Death Land Abandonment Drove European Diversity Losses. The Romans and their successors, with their cereals, olives and grapes, were surprisingly good for landscape floristic diversity. The Black Death, not so much.
- The decades-old fantasy of enhancing pigeonpea productivity. Well that’s a bit of a letdown after a 6 million year journey.
- Past, present and future of local crop evolution. That’s because we needed Indigenous people and local communities to show us the way.
Nibbles: Agricultural expansion maps, Brassica diversity, Not against the grain, South African seedbanks, Safer peanuts, Diné seedbank
- Agriculture is bad for natural ecosystems. But great for maps, you have to admit.
- Greens are good for you. And this is a great roundup of the latest scholarship on brassica evolution, domestication and diversity. You’ll find most of the paper quoted in past Brainfoods.
- Grains are great. Especially with greens.
- Thank goodness for household seed banking. Especially in conjunction with the formal kind.
- All so we can breed a better peanut. And cut down more natural ecosystem?
- No, there’s community genebanks for that too…
Brainfood: Diversity of Sugarcane, Rice, Lentils, Olives, Sweetpotato, Cassava, Beans, Buckwheat, Pigeon pea, Landscapes
- The genomic footprints of wild Saccharum species trace domestication, diversification, and modern breeding of sugarcane. The genome of modern sugarcane is a mosaic of wild introgressions, including one from an unknown source.
- Evolutionary histories of functional mutations during the domestication and spread of japonica rice in Asia. Selection by biotic stresses acted differently on standing variation in rice across geographic regions. Colour me surprised.
- Ancient DNA from lentils (Lens culinaris) illuminates human-plant-culture interactions in the Canary Islands. Local lentils trace back a thousand years in the Canaries.
- An olive parentage atlas: founder cultivars, regional diversification, and implications for breeding programs. Modern cultivars derive from a surprisingly small set of founding genotypes…
- Intraspecific variation and phenotypic plasticity of olive varieties in response to contrasting environmental conditions. …but cultivated olives maintain high within-species variation and plasticity, enabling adaptation across Mediterranean environments.
- Deciphering the Origins of Commercial Sweetpotato Genotypes Using International Genebank Data. One Brazilian sweetpotato traced back to a CIP accession with a different name, but others did not match anything in the genebank.
- Exploring genetic diversity and selective signatures, a journey through Colombian cassava’s landscape. Colombia’s farmers and environments have shaped its cassava diversity. No word on whether any of it traces back to the CIAT genebank.
- Novel germplasm of tepary and other Phaseolus bean wild relatives from dry areas of southwestern USA. The available genepool for bean breeding gets a welcome boost.
- Insight into root system architecture of buckwheat through genome-wide association mapping-first study. Want drought-resilient, high-yielding buckwheat varieties? Here are the genes — and genotypes — to play with. So the available genepool doesn’t need a boost?
- Non-destructive prediction of nitrogen, iron and zinc content in diverse common bean seeds from a genebank using near-infrared spectroscopy. High-throughput, non-destructive phenotyping methods capture nutritional trait variation across a bean core collection. Wild teparies unavailable for comment.
- Germplasm exploration and digital phenotyping reveal indigenous diversity and farmer preferences in pigeon pea (Cajanus cajan (L.) Millsp.) for climate-smart breeding. Not all phenotyping can be high-throughput, but that doesn’t mean it’s not useful, at least in pigeon peas.
- Agricultural landscape genomics to increase crop resilience. Could have been applied to all of the above, I guess.
Nibbles: Ancient Mexican seedbank, Indian millets, Foraged foods, Soybean breeding, Apple breeding, Albanian heirlooms, Bangladesh fish genebank
- People in the Nejapan Sierra Sur in Oaxaca, Mexico had a seed bank 400-700 years ago so they could re-create their complex cuisine after disruptions.
- How MSSRF revived millets in Odisha, India. You think a seed bank was involved?
- Meanwhile, in Meghalaya (also India), foraged foods are helping to diversify state-provided school lunches and address chronic malnutrition. Talk about complex cuisine. Are all these species in a seed bank somewhere, though? Do they need to be?
- How the National Soybean Germplasm Collection at the Agricultural Research Service lab in Urbana, Illinois helped save soybeans in Iowa.
- University breeding programmes are keeping the apple afloat in the USA. That and genebanks.
- Farmers and agrotourism are bringing back some cool flavors in Albania. Well, that and the Albanian Gene Bank.
- Fish need genebanks too, and Bangladesh is on it. Did ancient Bangladeshis have them, I wonder?
