- Made in Brazil? Brazil Nut, yes. The genus Manihot, not so much.
- The role of botanic gardens as resource and introduction centres in the face of global change. They have one. But they need to be more like genebanks.
- Global growth and stability of agricultural yield decrease with pollinator dependence. Analysis of time-series FAO production data shows that more pollinator-dependent crops have lower yield growth and lower yield stability. So both should benefit from more active management of wild pollinators and their habitats. Results can be extended to other ecosystem services but that was a bridge too far for this reader.
- Draft Policy Framework for Investment in Agriculture. “The purpose of this document is … to initiate discussion.” Off you go.
- Deterrent and insecticidal properties of bean seed (Phaseolus vulgaris L.) whole meal or protein extract incorporated into the diet of Callosobruchus maculatus (F.) (Coleoptera: Bruchidae). To protect chickpeas from bruchid beetles, add bean proteins.
- Community genetics: at the crossroads of ecology and evolutionary genetics, a special issue of the Philosophical Transactions of the Royal Society B, which includes …
- … Insect-resistant biotech crops and their impacts on beneficial arthropods. The abstract gives nothing away: “The findings … are discussed.”
- High connectivity among argali sheep from Afghanistan and adjacent countries means you need international collaboration for conservation. Good luck with that.
- Better phenomics and genomics means you can do really cool Genetic analysis of abiotic stress tolerance in crops, and their wild relatives of course. But we knew that.
- Five ways of Improving assessment and modelling of climate change impacts on global terrestrial biodiversity: more data, process-based modelling, better understanding of role of community interactions and of the effect of genetic variation, and better functional groupings of species for improved simulations of vegetation distribution.
Brainfood: Chia, Lentils, Bambara groundnut, Cacao, Amaranths, Rwanda, Cherimoya, Conservation, Drought, Plasticity, Phenology
- Extending the range of an ancient crop, Salvia hispanica L.—a new ω3 source. So we can grow it in the US, natch.
- Characterization of the lentil landrace Santo Stefano di Sessanio from Abruzzo, Italy. In the market, some are not what they claim to be; I’m shocked.
- Genetic diversity in Bambara groundnut (Vigna subterranea (L.) Verdc.) as revealed by phenotypic descriptors and DArT marker analysis. They’re pretty diverse, especially in Cameroon/Nigeria, which may be where they were domesticated.
- Genetic diversity and spatial structure in a new distinct Theobroma cacao L. population in Bolivia. They’re different from other cacao populations, and probably indigenous to Bolivia.
- Systematics and taxonomic delimitation of vegetable, grain and weed amaranths: a morphological and biochemical approach. Relationships? It’s complex.
- First and second millennium a.d. agriculture in Rwanda: archaeobotanical finds and radiocarbon dates from seven sites. Earliest pearl millet (Pennisetum glaucum), finger millet (Eleusine coracana) and sorghum (Sorghum bicolor) in the region, but do they really mean AD?
- The use of consecutive micrografting improves micropropagation of cherimoya (Annona cherimola Mill.) cultivars. It does, what more can I tell you?
- Social and ecological synergy: Local rulemaking, forest livelihoods, and biodiversity conservation. Big meta-analysis reveals complexity and the importance of participation by “local forest users.”
And here are a trio of rhyming couplets, if you see what I mean:
- The relative importance of drought and other water-related constraints for major food crops in South Asian farming systems. Drought and water constraints are widespread in South Asia. Though they contribute no more than 20-30% of current yield gaps, investment in genetic solutions needs to continue. Alas, there are significant Challenges in breeding for yield increase for drought. Nothing that can’t be overcome, though.
- Rethinking species’ ability to cope with rapid climate change. It’s the plasticity, stupid.
- Meta-analyses suggest strong selection on flowering phenology both in plants in general and in chickpea in particular.
Brainfood: Striga, Rice, Fish, Biofortification, Ecosystem functioning, Intercrops
OK, so we’re trying an experiment, siphoning off Nibbles about research, often in peer-reviewed journals, into their own hi-falutin’ cookie jar. We’ll probably publish once a week. And being here doesn’t mean we won’t revisit them later.
- Genetic diversity of a parasitic weed, Striga hermonthica, on sorghum and pearl millet in Mali. The parasite is diverse, but no differences in parasitized fields.
- Genetic differentiation among Sri Lankan traditional rice (Oryza sativa) varieties and wild rice species by AFLP markers. Four major clusters agree with morphology.
- Genetic variation in farmed populations of the gilthead sea bream Sparus aurata in Greece using microsatellite DNA markers. Farmed are less diverse and less heterozygous.
- Restoration of hay meadows on ex-arable land: commercial seed mixtures vs. spontaneous succession. No difference in long-term diversity, but there are other considerations.
- Bio-available zinc in rice seeds is increased by activation tagging of nicotianamine synthase. It works.
- Soil fauna alter the effects of litter composition on nitrogen cycling in a mineral soil. It’s complex; larger fauna affect N dynamics.
- Dry matter yield, nitrogen content, and competition in pea–cereal intercropping systems. Intercrops are more productive and deliver higher forage quality.
So what do you reckon? Is this worthwhile?
