- Rules for tree planting.
- Where those trees will have to come from: thousands of seed banks.
- Not if the tree is breadfruit, but that’s ok, there’s other ways to conserve the stuff.
- The impact of a single seed bank on rice improvement measured.
- The impact of Irish seed banks recognized.
- No need for genebanks to save heirloom wheats in Jordan.
- Lost opportunity to mention peanut genebanks, but that’s ok there’s other ways to conserve the stuff.
Nibbles: Old olive, Silphion, Heirloom watermelon, Calabrian chili, ICARDA genebank, Jamaica genebank, Tamil community seedbank, Forestry seeds
- Really old olive tree in the gardens of the mosque-cathedral of Cordoba is a lost variety.
- Long extinct medicinal spice plant not extinct after all?
- The next nearly extinct heirloom on our list is a watermelon from Virginia. Who knows, it may originally have been grown in Cordoba or Cyrenaica…
- And moving in the opposite direction, a really hot Calabrian chili pepper beats the heat.
- The ICARDA genebank is trying to find stuff that will beat the heat too.
- Jamaica is looking to beat the heat by establishing some new genebanks.
- Tamil Nadu going the community seedbank route, and why not? Jamaica please take note.
- An alliance of forestry outfits is pushing for a global seedbank infrastructure to support woodland restoration. Nothing if not ambitious. And much needed.
Nibbles: Food security, CWR, Rice, Food crisis, Yams, Peanuts, Tuscan wine, SADC seeds, Lonely trees
- Handy primer on the effects of climate change and biodiversity on food security, courtesy of the House of Lords.
- Crop wild relatives could help with all three.
- Trouble brewing for rice. House of Lords nodding wisely.
- The trouble that brewed for wheat wasn’t quite as advertised. Spoiler alert: the price spike had to do with China buying up all it could. So is rice next then?
- No trouble brewing for yams now that they’re getting sequenced.
- Nor for peanuts in the Gambia, for different reasons.
- Sounds like everything is hunky dory for the Tuscan grape too.
- Good to see SADC is on the job.
- It may be too late for some trees though.
Brainfood: Species mixtures double, Crop diversification, Local adaptation, Speed of adaptation, Essential Biodiversity Variables, Effective population size, Monitoring diversity
- Drought-exposure history increases complementarity between plant species in response to a subsequent drought. Repeated stress makes plant species get along better, sustaining diversity. If only it worked so well with people…
- A quantitative synthesis of soil microbial effects on plant species coexistence. Meta-analysis shows soil microbes work against plant species getting along better.
- Does crop diversification lead to climate-related resilience? Improving the theory through insights on practice. Crops getting along well together is pretty well linked to better livelihoods, but less strongly to increased resilience.
- Local Adaptation: Causal Agents of Selection and Adaptive Trait Divergence. You need to do reciprocal transplant experiments really well to find out where plants are best adapted and why. Probably means taking microbes into account.
- Genetic variance in fitness indicates rapid contemporary adaptive evolution in wild animals. Natural selection can be quicker than climate change. I hope they did the reciprocal transplant experiments really well.
- Global genetic diversity status and trends: towards a suite of Essential Biodiversity Variables (EBVs) for genetic composition. Genetic diversity, Genetic differentiation, Inbreeding, and Effective Population Size (Ne). Who needs reciprocal transplant experiments?
- On the feasibility of estimating contemporary effective population size (Ne) for genetic conservation and monitoring of forest trees. Ouch.
- Selecting species and populations for monitoring of genetic diversity. All of them, right?
Brainfood: Sweet potato in Polynesia, Land use in Jamaica, Himalayan Neolithic, Early modern Spanish ag, E Asian Neolithic double
- Sweet Potato on Rapa Nui: Insights from a Monographic Study of the Genus Ipomoea. Seeds could just maybe have got there by floating, but more likely sweet potato was introduced to Easter Island by people from other parts of Polynesia, perhaps not by the first arrivals though.
- The legacy of 1300 years of land use in Jamaica. European colonization led to deforestation. And no doubt the spread of sweet potato, but that’s another story. The constant is cassava.
- Prehistoric agricultural decision making in the western Himalayas: ecological and social variables. Large, socially diverse prehistoric sites had more diverse agriculture. At these high altitude anyway. The constant is barley.
- Early Austronesians Cultivated Rice and Millet Together: Tracing Taiwan’s First Neolithic Crops. That would be japonica rice and foxtail millet, which were brought to Taiwan from the SE coast of China.
- Millet, Rice, and Isolation: Origins and Persistence of the World’s Most Enduring Mega-State. Meanwhile, back in China, the adoption of agriculture drives state formation.
- A 16th-century biodiversity and crop inventory. 60 crop and livestock species, which doesn’t sound like enough. Alas, no sweet potato or rice, but some Setaria millet.
