- The Pear in History, Literature, Popular Culture, and Art. An oldie, but worth reading just for the analogy between the pear connoisseur and the opera aficionado.
- Effects of market integration on agricultural biodiversity in a tropical frontier. Darien, Panama. Roads are bad for crop diversity, of the interspecific kind at least.
- Conservation genetics and the persistence and translocation of small populations: bighorn sheep populations as examples. Bigger is definitely better.
- Niche breadth predicts geographical range size: a general ecological pattern. Specialist species tend to have small range sizes, making them doubly vulnerable. Trebly so if they have small populations too, I guess (see above).
- Sustainability and innovation in staple crop production in the US Midwest. …depends on on-farm diversity, and here’s three things you can do to promote it, because it ain’t getting any better: collect statistics, redirect subsidies, and think beyond peak yield. Ah but wait, you may have to change the IP system. As you were.
- Yield Trends Are Insufficient to Double Global Crop Production by 2050. For rice, wheat, maize and soybean, current rates of yield increase, if they continue, which I suppose is a big if, what with climate change and all, would mean about 50% production increases by 2050, rather than the supposedly needed 100%.
- Genome-Wide Genetic Diversity and Differentially Selected Regions among Suffolk, Rambouillet, Columbia, Polypay, and Targhee Sheep. Suffolk is different from the others, which we already knew were related. Ah, but now we know where exactly in the genome the differences are.
Nibbles: Indigenous conservation, Rice and conservation, Amazon medicines, Organic products, Sustainable oysters, Cherfas at Seed Savers, Calestous Juma, Cassava website, Israeli agritech, Fragaria breeding, Catacol whitebeam, Weather sensors, FAO Commission & Conference, Amartya Sen
- A toolkit to help indigenous communities do conservation. Should they need one.
- On the other hand… Half of Japan’s endangered species hotspots are found in satoyama, which are under pressure. Compare and contrast with rice farming in Thailand.
- Learn all about some medicinal plants of the Amazon, minus their scientific names. Not including runa tea. Lots of other opportunities out there, though.
- Maybe even including oysters.
- Jeremy no doubt to feast on the mollusc after spilling the beans on the EU seed regulations at the Seed Savers jamboree.
- Wonder what Calestous Juma thinks of those regulations.
- But I bet he (and his father, who introduced the crop to his region of Kenya) would like this cassava website to rule them all.
- The Volcani Institute‘s gifts to the world…
- …probably include new strawberries, but not this one.
- Scientists straining, failing to find plant to meaningfully compare to the giant panda.
- Bioversity does up its iButtons.
- And gets a namecheck in a paean to the FAO Commission on GRFA on its 30th birthday. All this FAO stuff is because its Conference is on this week. I don’t suppose any of it will be more important than Amartya Sen’s speech.
Brainfood: Maize domestication, Restoration success, Rare species, Pollinator loss, Diversity and productivity, Cacao/coffee & ecosystem services, Brazilian coffee, GM cotton benefits
- Genetics and Consequences of Crop Domestication. The domestication bottleneck has consequences.
- Evaluating Ecological Restoration Success: A Review of the Literature. There’s more of it going on. Evaluation, that is. Which is good. But still mainly from the USA and Australia, and not enough of the socioeconomic kind.
- Rare Species Support Vulnerable Functions in High-Diversity Ecosystems. Ecosystems are distinctive because of their rare species.
- Environmental factors driving the effectiveness of European agri-environmental measures in mitigating pollinator loss — a meta-analysis. We know how to lessen, but not how to mitigate, loss of pollinators.
- Experimental evidence that evolutionarily diverse assemblages result in higher productivity. And the more distantly related the species, the higher the productivity gain.
- A global meta-analysis of the biodiversity and ecosystem service benefits of coffee and cacao agroforestry. Agroforests better than plantations, but forests best of all.
- Coefficient of Parentage in Coffea arabica L. Cultivars Grown in Brazil. Be afraid.
- Genetically Modified Crops and Food Security. Turns out GM cotton has increased the income and thus improved the diets of adopting Indian farmers. Well, maybe.
Brainfood: Grass evolution, Great Lakes fisheries, African cassava, Sustainable UK farms, USA biodiversity loss, PVS, Agriculture to the rescue
- Evidence for recent evolution of cold tolerance in grasses suggests current distribution is not limited by (low) temperature. Geography a better predictor of cold tolerance than phylogeny.
- May we eat biodiversity? How to solve the impasse of conservation and exploitation of biodiversity and fishery resources. We may, if we all agree.
- Genetic diversity of cassava (Manihot esculenta Crantz) landraces and cultivars from southern, eastern and central Africa. There isn’t any.
- Evidence of sustainable intensification among British farms. Amazingly, there is some, and aiming to increase profitability can get you there.
- Key areas for conserving United States’ biodiversity likely threatened by future land use change. To the tune of 5-8% area loss, and not counting climate change. Would be interesting to know what that will do to crop wild relatives.
- Dilemma in participatory selection of varieties. If it’s a one-time deal, as it often is, it ain’t gonna work.
- Green Revolution research saved an estimated 18 to 27 million hectares from being brought into agricultural production. And saved 2 million ha of forest. But less than Borlaug thought. More on “Agricultural innovation to save the environment” from PNAS.
Getting past that 75%
China has lost 90% of the wheat varieties it had 60 years ago. The US has lost over 90% of the fruit tree and vegetable varieties it had at the start of the 20th century. Mexico has lost 80% of its corn varieties, India 90% of its rice varieties. In Spain, the number of melon varieties has gone down from nearly 400 in the early 1970s to a dozen.
What, not 75%? Anyway, too bad there are no references, but the Indian figure may come from the sources we discussed a while back. And of course “lost” is too dramatic. Some varieties may no longer be grown by farmers, but could still be in genebanks. But it is good to see a trope that’s well past its sell-by date being avoided for once.
