- Increases in crop pests caused by Wasmannia auropunctata in Solomon Islands subsistence gardens. Law of Unintended Consequences takes its toll. Or does it? Discussion at Pestnet suggests the Little Fire Ant may not have been introduced as a biological control agent as suggested by the paper.
- A Social-Ecological Analysis of Diversified Farming Systems: Benefits, Costs, Obstacles, and Enabling Policy Frameworks. Special issue of Ecology and Society on DFS. That would be Diversified Farming Systems. Bottom line is that you need to understand both their ecology and their politics to make sense of them, and make them work for you.
- Morphological diversity in breadfruit (Artocarpus, Moraceae): insights into domestication, conservation, and cultivar identification. 221 accessions provide exactly those insights.
- The original features of rice (Oryza sativa L.) genetic diversity and the importance of within-variety diversity in the highlands of Madagascar build a strong case for in situ conservation. Farms are more diverse than villages, which are more diverse than regions, so it may not take that much to conserve a lot of diversity in situ.
- More rapid and severe disease outbreaks for aquaculture at the tropics: implications for food security. Driven by environmental factors, and will get worse with climate change. Strangely, breeding for resistance, and genetic diversity in general, not mentioned.
- Cultivation of Domesticated Rice Alters Arthropod Biodiversity and Community Composition. Wild rice fields have different, less diverse arthropod communities.
- Quantifying habitat-specific contributions to insect diversity in agricultural mosaic landscapes. Some of the different bits of diverse landscapes in Switzerland have unique insects, which is apparently not the case in other places.
- Synergistic effects of non-Apis bees and honey bees for pollination services. And you do need lots of different insects, at least for pollination.
- Earth observation: overlooked potential to support species reintroduction programmes. Translocation and introductions are fraught, but if you still want to do them…
- An improved model to predict the effects of changing biodiversity levels on ecosystem function. Basically, the contribution of species 1 with relative abundance A and species 2 with relative abundance B to ecosystem function is AxB to the power of θ. Can it be extended to ecosystem services, I wonder?
- Pinot blanc and Pinot gris arose as independent somatic mutations of Pinot noir. So that’s where they came from. Insights into “[o]enological aptitude”.
- Divergent pattern of nuclear genetic diversity across the range of the Afromontane Prunus africana mirrors variable climate of African highlands. Sheds light on the history of Afromontane regions.
Brainfood: Core collections, Romanian pigs, Commons, Valuation, Biofortification, Yam characterization, Pompeii diet, Rice grain genetics
- Maximizing genetic differentiation in core collections by PCA-based clustering of molecular marker data. It works. In simulations, to be fair.
- Study of rare traditional pork breeds concerning the aspect of biodiversity conservation. Mangalitsa is what you want, apparently.
- Open Variety Rights: Rethinking the Commodification of Plants. A “protected commons”? Sounds a bit like the ITPGRFA to me.
- Natural and cultural heritage in mountain landscapes: towards an integrated valuation. Yeah, but does your cultural heritage include things like agricultural biodiversity?
- Fortifying plants with the essential amino acids lysine and methionine to improve nutritional quality. Conventional breeding hasn’t worked. But has it been for want of trying? Just askin’.
- Genetic and phenotypic diversity in a germplasm working collection of cultivated tropical yams (Dioscorea spp.). Relationships among species, synonyms, duplicates, yada yada.
- Roman food refuse: urban archaeobotany in Pompeii, Regio VI, Insula 1. Romans ate a Mediterranean diet. Still no cure for cancer.
- Genetic bases of rice grain shape: so many genes, so little known. Why bother? Just askin’.
Brainfood: Bumper bonanza, Old peas, Irrigated meadows, Cereal mashes, Medicinal plants, Diversity and production, Millet gaps, Seed ageing, Flax core
- First off — a pretty big deal. Taylor & Francis have made a bunch of papers related to sustainable agriculture freely available, but only until the end of December. Happy whatever holiday won’t offend you.
- Twentieth-century changes in the genetic composition of Swedish field pea metapopulations. Metapopulations have become isolated populations. In genebanks.
- Effects of different irrigation systems on the biodiversity of species-rich hay meadows. Change from the traditional irrigation system has affected biodiversity levels, but not a huge amount.
- Research regarding the use of wheat biodiversity for obtaining some cereal-based fermented mashes. Let’s go straight to what we need to know here: the best mash come from spelt wheat. Oh, to be the one doing the organoleptic characterization.
- Cultivation and high capitalization of medicinal and aromatic plants in the Romanian-Bulgarian cross-border region. If you’re really interested, there’s a database that brings it all together.
- Crop biodiversity, productivity and production risk: Panel data micro-evidence from Ethiopia. More crops = more production. But the devil is in the details, I suspect.
- Identification of gaps in pearl millet germplasm from East and Southern Africa conserved at the ICRISAT genebank. We used to do this sort of thing by hand in my day.
- At3g08030 transcript: a molecular marker of seed ageing. This mRNA could predict germination performance of a dry seed lot across species. Good for genebanks?
- Assembling a core collection from the flax world collection maintained by Plant Gene Resources of Canada. You don’t hear much about core collections these days, why is that?
Nibbles: Old rice, New quinoa, Fishy stuff, Cropland landscapes, Forest landscapes, Old seed, Superdomestication, Intensification
- Youth compiles list of rare and extinct rice varieties of Assam. Maybe he should look at weedy rice too?
- Meanwhile, American farmers are learning to grow quinoa, probably including some rare varieties.
- The smelliest fish in the world. No traceability needed for that one, I guess.
- Cropland getting mapped. Presumably including the Globally Important Agricultural Heritage Systems (GIAHS). Help needed by both, by the way.
- Follow the forest discussions at COP18. High on the agenda: what is a landscape? It’s what you study when you’re being holistic, no? Anyway, there’s got to be a connection to the previous links.
- Boffins find a genetic marker for old seed. Will need to Brainfood this one.
- Pat Heslop-Harrison breaks down superdomestication for you.
- SRI gets a scaling up. What could possibly go wrong?
Brainfood: Sierra Leone rice, Bean breeding, Cacao geographic diversity, Red fleshed apples, Species richness & productivity, African maize diversity, Human expansion, Barley gaps, Wild coffee and CC, Acacia and CC, Genetic erosion
- Analysis of genetic diversity in farmers’ rice varieties in Sierra Leone using morphological and AFLP markers. Still a lot of diversity in traditional rice after the war, both among and within landraces, mostly among, organized regionally, and recognized by local names.
- Simultaneous selection for resistance to five bacterial, fungal, and viral diseases in three Andean × Middle American inter-gene pool common bean populations. Thanks goodness for multiple independent domestication events. And genebanks.
- Present Spatial Diversity Patterns of Theobroma cacao L. in the Neotropics Reflect Genetic Differentiation in Pleistocene Refugia Followed by Human-Influenced Dispersal. So need to collect in areas at the margins or just outside the refugia if you want high diversity. But of course that may already be ex situ. But wait, didn’t you just do the analysis based on the provenance of ex situ holdings?
- An ancient duplication of apple MYB transcription factors is responsible for novel red fruit-flesh phenotypes. The whole genome got duplicated during evolution of the apple and the red flesh phenotype is controlled by loci in both copies, but in different ways.
- What is the form of the productivity–animal-species-richness relationship? A critical review and meta-analysis. Positive.
- Spatial Structure and Climatic Adaptation in African Maize Revealed by Surveying SNP Diversity in Relation to Global Breeding and Landrace Panels. Distinct Sahelian, Western and Eastern clusters. Some SNPs associated with high temperatures.
- MtDNA analysis of global populations support that major population expansions began before Neolithic Time. Humans needed good weather to thrive, not agriculture.
- Genetic gap analysis of wild Hordeum taxa. Argentina?
- The Impact of Climate Change on Indigenous Arabica Coffee (Coffea arabica): Predicting Future Trends and Identifying Priorities. Generally very bad to disastrous, but some “core localities” will be ok, and therefore could be used for in situ conservation. Interestingly, genebank accession locality data not used.
- The genus Acacia (Fabaceae) in East Africa: distribution, diversity and the protected area network. No such luck for Acacia, I’m afraid.
- Monocropping Cultures into Ruin: The Loss of Food Varieties and Cultural Diversity. Are you sure you want to know what a sociologist and a political scientist have to say on the matter?
