- Foods and fads: The welfare impacts of rising quinoa prices in Peru. Modest.
- Measuring the Affordability of Nutritious Diets in Africa: Price Indexes for Diet Diversity and the Cost of Nutrient Adequacy. Maybe they could try quinoa.
- Impacts of climate warming on terrestrial ectotherms across latitude. Insects are in trouble in the tropics, but will make up for it at higher latitudes, which will be really bad for crops there, 10-25% more bad.
- Evidence that organic farming promotes pest control. Something for farmers in those higher latitudes to think about.
- The global distribution of Bacillus anthracis and associated anthrax risk to humans, livestock, and wildlife. 63.8 million rural poor livestock keepers are at risk. No word on effect of climate change.
- Do open-pollinated maize varieties perform better than hybrids in agroforestry systems? Maybe in Rwanda, but in Ethiopia not so much.
- More than Yield: Ecosystem Services of Traditional versus Modern Crop Varieties Revisited. Landraces are liked for yield stability in marginal environments, and for cultural reasons.
- Root and shoot traits in parental, early and late generation Green Revolution wheats (Triticum spp.) under glasshouse conditions. Modern wheat have smaller roots.
- Standardized reporting of the costs of management interventions for biodiversity conservation. Behind a paywall, so can’t tell whether includes genebanks. But I bet it doesn’t. Tell me I’m wrong.
- Global assessment of agricultural system redesign for sustainable intensification. Apparently 30% of farms and 10% of agricultural land worldwide, which is both more and less than I would have guessed.
- Genetic homogeneity of North-African goats. The Berber breeds are different, everything else is a big mixed up mess.
- Plant domestication decreases both constitutive and induced chemical defences by direct selection against defensive traits. In cabbage, even the tissues that are not eaten are more edible than in the wild relative.
- Polyploid plants have faster rates of multivariate climatic niche evolution than their diploid relatives. Relevant for domestication?
- An Initiative for the Study and Use of Genetic Diversity of Domesticated Plants and Their Wild Relatives. In Mexico.
- Population structure, relatedness and ploidy levels in an apple gene bank revealed through genotyping-by-sequencing. There’s a lot of inter-relatedness in the Danish collection.
- Biases induced by using geography and environment to guide ex situ conservation. “Although geographic and environmental diversity have proven to be reliable predictors of allele frequency differences and ecotypic differentiation across species ranges, they appear to be poor predictors of allelic diversity per se.” At least for 3 species.
- Examining the spectra of herbarium uses and users. Herbaria mostly used by taxonomists shock.
- Ancient herders enriched and restructured African grasslands. Shit. You heard me.
R you interested in species distribution models?
If you always wanted to do species distribution modelling, it’s your lucky day. Let Robert Hijmans and Jane Elith take you by the hand.
This document provides an introduction to species distribution modeling with R. Species distribution modeling (SDM) is also known under other names including climate envelope-modeling, habitat modeling, and (environmental or ecological) niche-modeling. The aim of SDM is to estimate the similarity of the conditions at any site to the conditions at the locations of known occurrence (and perhaps of non-occurrence) of a phenomenon. A common application of this method is to predict species ranges with climate data as predictors.
Heritage cereals anyone?
In the middle of my recently completed magnum opus on wheat and bread, I got a message from Shelley at Against the Grain Farms in Canada. They’ve been working on restoring old varieties of wheat and barley for the past 31 years and they’re looking to contact farmers and researchers who would like to collaborate in some participatory plant breeding.
Brainfood: Fox domestication, Wheat synthesis, Microscale selection, Sports, Brinjal evolution, Famous faba, Synthetic wheats, Watkins collection, Wheat genetic gains, Chinese cattle
- Red fox genome assembly identifies genomic regions associated with tame and aggressive behaviours. It’s down to synaptic plasticity, among other things.
- Development and identification of new synthetic T. turgidum–T. monococcum amphiploids. Did this never happen in the wild?
- Genomic adaptation to drought in wild barley is driven by edaphic natural selection at the Tabigha Evolution Slope. Big genetic differences in wild populations just meters apart but on different soil types.
- Attention sports fans! The far-reaching contributions of bud sport mutants to horticulture and plant biology. Much more than just Pinot gris.
- Shedding new light on the origin and spread of the brinjal eggplant (Solanum melongena L.) and its wild relatives. Originated in Africa, moved to Asia, where it was domesticated; spread in Africa by elephants.
- ILB 938, a valuable faba bean (Vicia faba L.) accession. Goes well with chianti. Note the DOI.
- Unlocking the novel genetic diversity and population structure of synthetic Hexaploid wheat. More in diversity in synthetics compared to elite bread wheats.
- Genetic Gains for Grain Yield in CIMMYT’s Semi-Arid Wheat Yield Trials Grown in Suboptimal Environments. 1.6% per year (2002-2014), not least because of the above.
- Hidden variation in polyploid wheat drives local adaptation. Could this contribute to continuing the above?
- Genome-wide scanning reveals genetic diversity and signatures of selection in Chinese indigenous cattle breeds. More diversity in the north.
Brainfood: Food as art, Maize seed, Jatropha genome, Wild camelids, Global nutrition, Price shocks, Pearl millet domestication, Yam domestication, NNL, New beer microbe, Dog coat colour, Herbarium biases, Maize N fixation
- Food as a daily art: ideas for its use as a method in development practice. Food can bring traditional and scientific knowledge together in an smorgasbord of ideas.
- Maize seed systems in different agro-ecosystems; what works and what does not work for smallholder farmers. Sure, purchasing hybrids from the formal sector seed system is gaining ground in Malawi, Zambia, and Chiapas, but not for home consumption, and only in high potential areas.
- Genome sequence of Jatropha curcas L., a non‐edible biodiesel plant, provides a resource to improve seed‐related traits. Is Jatropha even still a thing?
- Comparing genetic diversity and demographic history in co-distributed wild South American camelids. Vicuña (alpaca wild relative) display lower genetic diversity within populations than guanaco (llama) but more structure across Peru; strong bottlenecks happened at different times, but in both cases much later than domestication and before Spanish conquest.
- The Global Nutrient Database: availability of macronutrients and micronutrients in 195 countries from 1980 to 2013. Supply of micronutrients has increased during the period globally and across levels of development.
- Effects of Food Prices on Poverty: The Case of Paraguay, a Food Exporter and a Non-Fully Urbanized Country. Food price hikes are, overall, bad for everyone, but least bad for the poorest and richest.
- A western Sahara centre of domestication inferred from pearl millet genomes. Harlan’s non-centre not found. Free-to-read.
- Molecular basis of African yam domestication: analyses of selection point to root development, starch biosynthesis, and photosynthesis related genes. Domestication of wild yams was all about learning to grow in full sunlight, and it involved losing 30% of their diversity. But remember current wild yams are not all that wild.
- No net loss for people and biodiversity. How to ensure that people really are no worse off after an offset intervention.
- Identification of a novel interspecific hybrid yeast from a metagenomic open fermentation sample using Hi-C. Doesn’t work on its own, though.
- Length variations within the Merle retrotransposon of canine PMEL: correlating genotype with phenotype. Mobile DNA gets everywhere.
- Widespread sampling biases in herbaria revealed from large‐scale digitization. Blame mega-collectors.
- Nitrogen fixation in a landrace of maize is supported by a mucilage-associated diazotrophic microbiota. In aerial roots, no less.
