- Relating dietary diversity and food variety scores to vegetable production and socio-economic status of women in rural Tanzania. Dietary diversity was all too often alarmingly low, and when it was it was associated with seasonal fluctuations in the production and collecting of vegetables. But a more varied diet need not necessarily be healthier, so more procedural sophistication will be necessary in follow-up studies.
- A risk-minimizing argument for traditional crop varietal diversity use to reduce pest and disease damage in agricultural ecosystems of Uganda. For Musa and beans, more varietal diversity meant less damage and less variation in damage.
- Exploring farmers’ local knowledge and perceptions of soil fertility and management in the Ashanti Region of Ghana. Soils which farmers described as being more fertile were, ahem, more fertile.
- Population genetics of beneficial heritable symbionts. Of insects, that is. Important because they can confer protection from natural enemies, among other things. They behave a bit, but not entirely, like beneficial nuclear mutations.
- Widespread fitness alignment in the legume–rhizobium symbiosis. There are no cheaters.
- Genetic polymorphism in Lactuca aculeata populations and occurrence of natural putative hybrids between L. aculeata and L. serriola. Not much diversity in Israel, surprisingly. But isozymes?
- Meta-Analysis of Susceptibility of Woody Plants to Loss of Genetic Diversity through Habitat Fragmentation. The standard story — that trees suffer less genetic erosion because they are long-lived — is apparently wrong, even for wind pollinated trees.
- Large-scale cereal processing before domestication during the tenth millennium cal BC in northern Syria. “This was a community dedicated to the systematic production of food from wild cereals.”
- Nazareno Strampelli, the ‘Prophet’ of the green revolution. Before Norman, there was Nazareno.
- The memory remains: application of historical DNA for scaling biodiversity loss. Historical collections of salmon scales reveal many connections between modern evolutionary significant units (ESUs) in the Columbia River and old ones; but also, intriguingly, some differences.
Brainfood: Cattle, Coffee pest management
- Modern Taurine Cattle descended from small number of Near-Eastern founders. Only 80 founding females, so it was difficult.
- Implementing an Integrated Pest Management Program for Coffee Berry Borer in a Specialty Coffee Plantation in Colombia. It wasn’t easy, and it took time, but it worked; less pesticides, more predators, higher quality beans.
Brainfood: Beans, Potatoes, Lettuce, Agave, Gaming, Mangroves, Ancient millets, Ancient missions
- Mesoamerican origin of the common bean (Phaseolus vulgaris L.) is revealed by sequence data. Revealed is kinda strong isn’t it? This from a bean expert of my acquaintance: “Yes, we knew that, as it seems to be the case of all species of the Phaseoli section. They could have done a bit better in including the 2 populations of Cordoba mountain, in order to see whether these belong to the first migration to the Andes, or the second one. Wild vulgaris from western Panama, or Venezuela, could have helped in this regard too. We have shown years ago that the complex genetic structure in Mexico and in Colombia is the result of these floristic migrations combined with gene flow events because beans cross among themselves.”
- The Enigma of Solanum maglia in the Origin of the Chilean Cultivated Potato, Solanum tuberosum Chilotanum Group. These are long-day adapted and therefore crucial to the history of the potato in Europe. But the various sorts of evidence looked at to investigate their relationship to the rare Chilean wild relative S. maglia just do not agree. Bummer.
- Wild and weedy Lactuca species, their distribution, ecogeography and ecobiology in USA and Canada. So Iowa is a wild lettuce hotspot. If you’re interested in the germplasm, it’ll be in the genebank of Palacký University in the Czech Republic.
- Sustainability of the traditional management of Agave genetic resources in the elaboration of mezcal and tequila spirits in western Mexico. Tequila industrial agriculture should learn from the traditional kind.
- Fate of the World: computer gaming for conservation. Worth a try. No, really.
- The Economic Value of Mangroves: A Meta-Analysis. You might think there would be a value in the abstract; you would be wrong.
- Early millet use in northern China. That would be Setaria italica and Panicum miliaceum, and new evidence from ancient starch grain on pottery and grinding stones found in archaeological sites has pushed back their cultivation in N China by 1000 and 2000 years respectively, to about 9500-7500 BC. The Archaeobotanist has more, as ever.
- Digitization and online availability of original collecting mission data to improve data quality and enhance the conservation and use of plant genetic resources. They’re there (and here; what’s up with that?) to consult and make use of if you want.
And don’t forget, you can join our group on Mendeley, subscribe to the feed, and have all this filtered goodness delivered to the RSS reader of your choice.
Brainfood: Water, Policy, Geneflow
- The water footprint of humanity. Someday you’ll need this. Maybe not today. Maybe not tomorrow, but soon and for the rest of your life.
- Evolution in biodiversity policy – current gaps and future needs. EU policies are all but useless; but you knew that.
- Genomic regions in crop–wild hybrids of lettuce are affected differently in different environments: implications for crop breeding. To prevent the spread of GMO genes to wild relatives, it matters where you make the insertion.
Brainfood: Bison on the prairie, Tilapia breeding, AM on banana, Phenomics,Yam collection, Nopales, Arable flora
- Can bison play a role in conserving habitat for endangered sandhills species in Canada? Maybe, hence the recommendation to re-introduce them. Incidentally, there are a few crop wild relatives on the list of threatened plants of Canada.
- Genetic improvement of farmed tilapias: Genetic parameters for body weight at harvest in Nile tilapia (Oreochromis niloticus) during five generations of testing in multiple environments. The 10-year “Genetic Improvement of Farmed Tilapias” (GIFT) project was not a complete waste of time. The GIFT population will respond well to selection for increased body mass, and you dont have to do the evaluation in lots of different environments.
- Mycorrhizal colonization of major banana genotypes in six East African environments. Different banana genotypes had different levels of infection, but environment also plays an important role. Important because arbuscular mycorrhizal fungi may increase production.
- On the use of depth camera for 3D phenotyping of entire plants. An example of this.
- Genetic and phenotypic diversity in a germplasm working collection of cultivated tropical yams (Dioscorea spp.). Should be a good starting point for improvement programmes. Kind of like the GIFT population, then, eh? But starting point? Haven’t people been breeding yams for a while?
- Cytogeography of the Humifusa clade of Opuntia s.s. Mill. 1754 (Cactaceae, Opuntioideae, Opuntieae): correlations with pleistocene refugia and morphological traits in a polyploid complex. The southeastern and southwestern U.S. represent glacial refugia for diploid members of the clade, and a whole bunch of polyploids resulted when the taxa spread out again after glacial episodes. How many of these are eaten is what I’d like to know, and whether ploidy affects that. I suppose climate change will lead to further complications?
- The impact of agricultural intensification and land-use change on the European arable flora. Is significant. Not least because some crop wild relatives are involved, although that’s not really discussed here.
