- 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.

- 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.

Brainfood: Chinese fermented fish, Yeast diversity, Wild papayas, Milpa nutrition, Rare wild sunflower, Albanian pomegranate, Wheat mixtures, Climate change yield decline
- Chemical and microbial properties of Chinese traditional low-salt fermented whole fish product Suan yu. “The values of Enterobacteria and Pseudomonads were under the detection limits in six different brands” is about the best that can be said for it.
- Tapping into yeast diversity. Some new, diverse wild lineages in China may tell us important things about yeast ecology, evolution and domestication.
- Genome size variation among sex types in dioecious and trioecious Caricaceae species. Lots of retrotransposons, and sex chromosomes in some species.
- The Archaic Diet in Mesoamerica: Incentive for Milpa Development and Species Domestication. The diet preceded the crops.
- Genetic diversity and population structure in the rare Algodones sunflower (Helianthus niveus ssp. tephrodes). Low diversity overall, but some populations quite distinct. Which tells you about how to conserve it.
- Albania, the domestication country for pomegranate (Punica granatum L.). Well, maybe.
- Mixtures of genetically modified wheat lines outperform monocultures. Two transgenes are better than one.
- Climate change impacts on crop productivity in Africa and South Asia. -8% overall. The surprise? Sorghum declines more than maize in Africa, less in S Asia.
Brainfood: Pedodiversity, Rice and CC, Bean domestication, Cassava mealybug, Grape relationships, Habitat conservation, Extinction and CC, Local provenance, Speciation, Breeding for climate change, Melon diversity, Eucalypt mating, Diverse croppping systems
- Archive and refugia of soil organisms: applying a pedodiversity framework for the conservation of biological and non-biological heritages. They want to set up a network of soil reserves. To conserve the likes of dung beetles, among other things (see last week’s Brainfood). Someone will no doubt mash this up with nature reserves and other protected areas in due course.
- Climate warming over the past three decades has shortened rice growth duration in China and cultivar shifts have further accelerated the process for late rice. One degree increase in temperature translates to about a 4 day shortening of growth period. But the problem would not be so bad if short-duration cultivars were not being increasingly used. No, I don’t fully get it either, but it seems interesting.
- Multiple origins of the determinate growth habit in domesticated common bean (Phaseolus vulgaris). The gene in question, part of the domestication syndrome, has been messed about in a variety of distinct and independent ways.
- The Cassava Mealybug (Phenacoccus manihoti) in Asia: First Records, Potential Distribution, and an Identification Key. Bad news for “the southern end of Karnataka in India, the eastern end of the Ninh Thuan province in Vietnam, and in most of West Timor in Indonesia.” No resistance. Yet.
- Genetic relationship between Chinese wild Vitis species and American and European Cultivars based on ISSR markers. It is limited. That goes for the wilds too.
- Synergies and trade-offs between ecosystem service supply, biodiversity, and habitat conservation status in Europe. What’s good for the environment is good for the environment. Or if you prefer the non-smartass version, get it from the horse’s mouth…
- Development of best practices for ex situ conservation of radish germplasm in the context of the crop genebank knowledge base. See the results for yourself.
- How does climate change cause extinction? Not so much because of intolerance to high temperatures as due to disruption of relationships with other species, as it turns out. But it’s a small sample.
- Testing the “Local Provenance” Paradigm: A Common Garden Experiment in Cumberland Plain Woodland, Sydney, Australia. No difference between locally sourced and more “exotic” provenances. Bang goes that paradigm.
- Mapping the genomic architecture of ecological speciation in the wild: does linkage disequilibrium hold the key? Clever shortcut allows identification of key genes separating phenotypically distinct but admixing species. I think. It’s complicated.
- Breeding Strategies for Adaptation of Pearl Millet and Sorghum to Climate Variability and Change in West Africa. Anything that keeps diversity in the system, basically.
- Estimation of phenotypic divergence in a collection of Cucumis melo, including shelf-life of fruit. Old-fashioned morphological characterization of small Indian collection confirms distinction between botanical varieties. Not many people hurt.
- Pollen diversity matters: revealing the neglected effect of pollen diversity on fitness in fragmented landscapes. Fragmentation means lower pollen diversity in Eucalyptus sp., means lower progeny fitness, and not just because of inbreeding.
- Increasing Cropping System Diversity Balances Productivity, Profitability and Environmental Health. So let me get this straight. You mean to tell me that a little bit of industrial agriculture (synthetic inputs) can combine with a little bit of ecoagriculture (cropping diversity) to give you something that’s kinda better than both?
Brainfood: Biodiversity surveys, Potato innovation, Wild sorghum, Bumblebee decline, Naked barley, Primate deterrents, Pastoralism, Mapping, Japanese forests, Aquaculture, Birds, Lentil mixtures, Eucalypt plantations, Seed adoption, Altai nomadism, Dung beetle diversity
- Systematic, large-scale national biodiversity surveys: NeoMaps as a model for tropical regions. The Neotropical Biodiversity Mapping Initiative (NeoMaps) provides good estimates of species richness, composition and relative abundance, in about 1 month of fieldwork per major taxonomic group and about US$ 1–8 per sq km. Now to do something similar for crop diversity.
- Insights into potato innovation systems in Bolivia, Ethiopia, Peru and Uganda. Rapid appraisal of potato innovation system by CIP et al. reveals differences among countries, but significant role of CIP across countries. Roles of farmer organizations and input supply companies limited everywhere.

- Role of eucalypt and other planted forests in biodiversity conservation and the provision of biodiversity-related ecosystem services. They can provide an opportunity for forest restoration, but it will take some rethinking. The mother-in-law will be pleased.
- Influence of Sources of Seed on Varietal Adoption Behavior of Wheat Farmers in Indo-Gangetic Plains of India. You need to get the message out if you want your improved varieties adopted. Can’t imagine you’d need a multinomial logit model to figure that out.
- Pastoral nomadism in the forest-steppe of the Mongolian Altai under a changing economy and a warming climate. As transport costs go up, and goat numbers increase because of cash from cashmere, mobility decreases and overgrazing results. A traditional way of life becoming unsustainable before your eyes.
- Species-rich dung beetle communities buffer ecosystem services in perturbed agro-ecosystems. Functional redundancy is not redundant after all.
