- Complementary effects of species and genetic diversity on productivity and stability of sown grasslands. Species diversity good for total production, genetic diversity good for regular production throughout the year, regardless of water. And more, and more.
- Genetic Diversity and Population Structure Patterns in Chinese Cherry (Prunus pseudocerasus Lindl) Landraces. Perhaps 2 domestication sites.
- Inter-individual variation promotes ecological success of populations and species: evidence from experimental and comparative studies. More diverse populations are less vulnerable to environmental changes, more stable in population size, less extinction prone, have better establishment success and larger ranges, especially under stress.
- Ecogeography and utility to plant breeding of the crop wild relatives of sunflower (Helianthus annuus L.). Many close relatives of the crop in extreme environments.
- Domestication of small-seeded lima bean (Phaseolus lunatus L.) landraces in Mesoamerica: evidence from microsatellite markers. Two domestications events. Maybe.
- Trends in genetic diversity for all Kennel Club registered pedigree dog breeds. Popular sires have made for a lot of inbreeding, but this has been getting better of late.
- The N’Dama dilemma: ethnogenetics and small ruminant breed dynamics in the tsetse zone, The Gambia. Saving the name is not enough.
- The Pig and the Chicken in the Middle East: Modeling Human Subsistence Behavior in the Archaeological Record Using Historical and Animal Husbandry Data. Chickens replaced pigs in the first millennium Middle East because they were smaller and more efficient. Oh, and eggs.

- In the Footsteps of Vavilov: Plant Diversity Then and Now. The Pamiri Highlands of Tajikistan, the Ethiopian Highlands, and the Colorado Plateau of Southwestern North America compared at time of Vavilov and now: “Localities that have retained diversity have suffered the least.”
- Vavilovian Centers of Plant Diversity: Implications and Impacts. “His concept of specific centers of origin for crop plants was not an isolated aphorism but has directed breeders, on their study and reflection, to the continued improvement and economic development of plants for humanity.”
- Mitochondrial DNA variation of Nigerian domestic helmeted guinea fowl. Recent domestication, and lots of intermixing mean not much diversity, and what there is doesn’t have structure.
- Genome-wide association and genomic prediction of resistance to maize lethal necrosis disease in tropical maize germplasm. That’s when two viruses attack synergistically. Resistance is from multiple loci with smallish effects, and there are some promising markers.
- Genome-environment associations in sorghum landraces predict adaptive traits. Genotype predicts drought tolerance.
- Facilitation and sustainable agriculture: a mechanistic approach to reconciling crop production and conservation. Understanding facilitative plant–plant interactions (intercropping, varietal mixtures) in crops leads to more sustainable farming practices. Or it could.
- The relative contribution of climate and cultivar renewal to shaping rice yields in China since 1981. Mainly new varieties. Climate change has actually helped, but for how long?
- Biodiversity inhibits parasites: Broad evidence for the dilution effect. Meta-analysis shows biodiversity decreases parasitism and herbivory.
- Using genomic repeats for phylogenomics: a case study in wild tomatoes (Solanum section Lycopersicon: Solanaceae). Data that are usually thrown away turn out to be useful for something after all.
- Genetic structure of the date palm (Phoenix dactylifera) in the Old World reveals a strong differentiation between eastern and western populations. Asian and African genepools, with geneflow E to W.

- Genetic structure and internal gene flow in populations of Schinus molle (Anacardiaceae) in the Brazilian Pampa. Try to keep what forest patches remain. And link them up somehow.
- Genetic Diversity of Buckwheat Cultivars (Fagopyrum tartaricum Gaertn.) Assessed with SSR Markers Developed from Genome Survey Sequences. Two groups, overlapping in Qinghai, China.
- Increases in the longevity of desiccation-phase developing rice seeds: response to high-temperature drying depends on harvest moisture content. Genebanks may have it wrong for seeds of rice (and perhaps other tropical species) harvested while still metabolically active: these you can dry at higher temperatures than is the norm.
- Vitis International Variety Catalogue (VIVC): A cultivar database referenced by genetic profiles and morphology. Now with added microsatellites.
- Options for enhancing efficiency and effectiveness of research capacity for livestock genetics in, and for, sub-Saharan Africa. Embed in wider rural development, collaborate, and share data. Could apply to more than just livestock improvement.
- Mapping and validating predictions of bacterial biodiversity using European and national scale datasets. It’s the pH.
- Agricultural Extension Roles towards Adapting to the Effects of Taro Leaf Blight (Tlb) Disease in Nsukka Agricultural Zone, Enugu State. Basically, extensionists haven’t done a thing.
- Anthropogenic drivers of plant diversity: perspective on land use change in a dynamic cultural landscape. Abandoning farmland is not good for biodiversity.
- Agricultural landscapes and biodiversity conservation: a case study in Sicily (Italy). Ahem. Abandoning farmland is not good for biodiversity.
- Genetic diversity of Faidherbia albida (Del.) A. Chev accessions held at the World Agroforestry Centre. It’s not enough.
