- The Value of Biodiversity as an Insurance Device. So apparently the “Epstein-Zin-Weil specification of the utility function allows us to disentangle the effects of risk aversion and aversion to fluctuations.” Good to know.
- The Invasive Legacy of Forage Grass Introductions into Florida. Sometimes biodiversity is bad for you, Epstein-Zin-Weil specification or not.
- Cultigen Chenopods in the Americas: A Hemispherical Perspective. Why did the North American one not do a quinoa?
- The potential of landscape genomics approach in the characterization of adaptive genetic diversity in indigenous goat genetic resources: A South African perspective. “[N]on-descript indigenous veld goats” no longer.
- Collection and characterization of grapevine genetic resources (Vitis vinifera) in the Holy Land, towards the renewal of ancient winemaking practices. Some of the local varieties could make a decent tipple.
- Genetic studies regarding the control of seed pigmentation of an ancient European pointed maize (Zea mays L.) rich in phlobaphenes: the “Nero Spinoso” from the Camonica valley. But do we really want to promote a landrace as a functional food?
- Genetic diversity patterns in ex situ collections of Oryza officinalis Wall. ex G. Watt revealed by morphological and microsatellite markers. Malesia separates out from SE Asia, and similarities between PNG and Philippines points to long-distance dispersal by birds. Or germplasm collectors.
- Perceptual selection and the unconscious selection of ‘volunteer’ seedlings in clonally propagated crops: an example with African cassava (Manihot esculenta Crantz) using ethnobotany and population genetics. Occasional seedlings are allowed to survive not so much because they look different, but because they look similar, to existing landraces, even though they may be genetically distinct.
- Evolutionary “Bet-Hedgers” under Cultivation: Investigating the Domestication of Erect Knotweed (Polygonum erectum L.) using Growth Experiments. Experimental domestication pretty quickly gets rid of that peskily bet-hedging germination heteromorphism.
- Are We Getting Better at Using Wild Potato Species in Light of New Tools? Not until we move on from conserving populations and start documenting individual plants in depth.
- Crucible of Crop Diversity: Forging Partnership with Farmer Breeders and Innovators for Higher Climate Resilience. Experience of the Honey Bee Network in bringing together farmers and researchers.

- Harnessing diversity from ecosystems to crops to genes. “…currently, approximately 75% of the genetic diversity of crops may have been lost.” I do like that “may.”
- Multivariate analysis of morphological diversity among closely related Daucus species and subspecies in Tunisia. The revenge of morphology: D. sahariensis, plus 4 subspecies of D. carota.

- Alexis Soyer was apparently the first celebrity chef.
- EMBRAPA gets to grips with crop wild relatives, with a little help from their friends.
- Did they serve brigaidero, though?
- Take part in a crowd-sourced experiment on plant adaptation.
- And then go and find out how the experts do it.
- Will fonio‘s day ever come?
- Celebrating the milpa.
- Gotta eat your broccoli fresh for the full nutrient monty.
- Putting (yet another) value on biodiversity. This one by adding or subtracting a species to a grassland plot and seeing what happens to C sequestration.
- What price soybeans?
Brainfood: Banana identification, Donkey domestication, Mouse domestication, African cattle, Pig domestication, Biofuels, Biofortification, Genomics for breeding, Species movement, Crop diversity double, N fixation, Ag commercialization models, Wild beans, Brassica domestication, Teaching biodiversity
- Molecular and cytological characterization of the global Musa germplasm collection provides insights into the treasure of banana diversity. 16% of 1500 accessions need taxonomic verification. Could have been much worse.
- Why the Donkey Did Not Go South: Disease as a Constraint on the Spread of Equus asinus into Southern Africa. Gap in distribution between Kenya and southern Africa until colonial times probably down to trypanosomiasis.
- Origins of house mice in ecological niches created by settled hunter-gatherers in the Levant 15,000 y ago. Hunter gatherers inadvertently domesticated the mouse.
- The genome landscape of indigenous African cattle. Now we know where the genes for heat tolerance and tick resistance can be found, and it’s where you’d think.
- Insights into early pig domestication provided by ancient DNA analysis. In northern Europe, around 4000 BC, people started crossing pigs from the south with local wild boars. What were they thinking?
- Recent grassland losses are concentrated around U.S. ethanol refineries. The revenge of geography.
- Provitamin A biofortification of crop plants: a gold rush with many miners. “One crucial aspect that needs further experimentation is whether β-carotene-fortified crops can improve vitamin A status in the main targets of the biofortification efforts, that is, malnourished adults and children.” Just going to leave that out there.
- Genomic innovation for crop improvement. Longer reads needed. Is there no satisfying these gene-jockeys?
- Biodiversity redistribution under climate change: Impacts on ecosystems and human well-being. Species movements affect ecosystem functioning and service provision: “The indirect effects of climate change on food webs are also expected to compound the direct effects on crops.”
- Feeding the Household, Growing the Business, or Just Showing Off? Farmers’ Motivations for Crop Diversity Choices in Papua New Guinea. Some people grow lots of crops because it’s cool. But why wasn’t this done at the intraspecific level?
- To Specialize or Diversify: Agricultural Diversity and Poverty Dynamics in Ethiopia. Forget coolness, crop diversity makes you less poor.
- Biogeography of nodulated legumes and their nitrogen-fixing symbionts. Australia is weird.
- Plantations, outgrowers and commercial farming in Africa: agricultural commercialisation and implications for agrarian change. They all have their place.
- Genomic history of the origin and domestication of common bean unveils its closest sister species. Wild populations from northern Peru and Ecuador are not derived from wild Phaseolus vulgaris which migrated there from Mesoamerica but are actually a different species which predates the evolution of wild common bean.
- Genomic inferences of domestication events are corroborated by written records in Brassica rapa. Five genetic groups, with rapini at the base.

Brainfood: Soil biodiversity maps, VIR wheat, Rice worlds, African maize, Cold rice, Saharan history, Oil palm & CC, GM Cavendish
- Assessing soil biodiversity potentials in Europe. The hotspots are the pastures and grasslands of Ireland, Slovenia and Sweden.
- Into the vault of the Vavilov wheats: old diversity for new alleles. VIR has diversity that’s not in CIMMYT and Australian cultivars. No word on where ICARDA fits in.
- Disembedding grain: Golden Rice, the Green Revolution, and heirloom seeds in the Philippines. There are parallel and competing rice worlds, which differ in how they valorize the local. Or, it could be argued, though not by the authors, demonize the “other.”
- Microsatellite DNA marker for molecular characterization of African maize (Zea mays L.) landraces. The Somali material is weird.
- Genetic architecture of cold tolerance in rice (Oryza sativa) determined through high resolution genome-wide analysis. 42 QTLs. Is that a lot? It seems like a lot.
- Humans as Agents in the Termination of the African Humid Period. Damn livestock. Back to hunting and gathering.
- Future climate effects on suitability for growth of oil palms in Malaysia and Indonesia. Well that’s ironic.
- Golden bananas in the field: elevated fruit pro-vitamin A from the expression of a single banana transgene. Gene from Fe’i biofortifies Cavendish. Now to do something about taste, texture, general suckiness etc etc.
Brainfood: Hot pepper double, Tibetan chickens, Watermelon diversity, Sunflower accessions, CWR meh, E Africa early ag, Pristine myth, African deforestation
- Screening old peppers (Capsicum spp.) for disease resistance and pungency-related traits. Resistance does not correlate with geography within an Andean collection.
- Bioactive Compound Variability in a Brazilian Capsicum Pepper Collection. No accession is high in everything.
- Genetic evidence from mitochondrial DNA corroborates the origin of Tibetan chickens. That is, the surrounding regions.
- Morphological and genetic diversity analysis of Citrullus landraces from India and their genetic inter relationship with continental watermelons. Modern cultivars are homogeneous.
- Molecular diversity of sunflower populations maintained as genetic resources is affected by multiplication processes and breeding for major traits. Multiplication slightly reduces within-accession diversity. Well, in France anyway.
- Past and Future Use of Wild Relatives in Crop Breeding. Yada yada.
- Subsistence mosaics, forager-farmer interactions, and the transition to food production in eastern Africa. The transition to agriculture in E Africa was more than just the Bantu expansion.
- Persistent effects of pre-Columbian plant domestication on Amazonian forest composition. Domesticated species are more common around archaeological sites. Sounds like agriculture is not much more than the Arawakan and Tupí expansions.
- Human population growth offsets climate-driven increase in woody vegetation in sub-Saharan Africa. In some places climate change has positive effects, but these are swamped where there is high population growth.
