Domesticated species are impacted in unintended ways during domestication and breeding. Changes in the nature and intensity of selection impart genetic drift, reduce diversity, and increase the frequency of deleterious alleles. Such outcomes constrain our ability to expand the cultivation of crops into environments that differ from those under which domestication occurred. We address this need in chickpea, an important pulse legume, by harnessing the diversity of wild crop relatives. We document an extreme domestication-related...

Data from: Maize-nutrient response information applied across Sub-Saharan Africa

The profit potential for a given investment in fertilizer use can be estimated using representative crop nutrient response functions. Where response data is scarce, determination of representative response functions can be strengthened by using results from homologous crop growing conditions. Maize (Zea mays L.) nutrient response functions were selected from the Optimization of Fertilizer Recommendations in Africa (OFRA) database of 5500 georeferenced response functions determined from field research conducted in Sub-Saharan Africa. Three methods for...

Data from: Patterns of domestication in the Ethiopian oil-seed crop Noug (Guizotia abyssinica)

Hannes Dempewolf, Misteru Tesfaye, Abel Teshome, Anne Bjorkman, Rose L. Andrew, Moira Scascitelli, Scott Black, Endashaw Bekele, Johannes M. M. Engels, Quentin C. B. Cronk, Loren H. Rieseberg & Anne D. Bjorkman
Noug (Guizotia abyssinica) is a semi-domesticated oil-seed crop, which is primarily cultivated in Ethiopia. Unlike its closest crop relative, sunflower, noug has small seeds, small flowering heads, many branches, many flowering heads, indeterminate flowering, and it shatters in the field. Here we conducted common garden studies and microsatellite analyses of genetic variation to test whether high levels of crop-wild gene flow and/or unfavorable phenotypic correlations have hindered noug domestication. With the exception of one population,...

Spatial and temporal genetic variation in Ethiopian barley (Hordeum vulgare L.) landraces as revealed by simple sequence repeat (SSR) markers

Allo Aman Dido, B.J.K Singh, Ermias Assefa, M.S.R. Krishna, Dawit Degefu & Kassahun Tesfaye
Ethiopia is a center of diversity for barley (Hordeum vulgare L.) and it is grown across different agro-ecologies of the country. Unraveling population structure and gene flow status on temporal scales assists an evaluation of the consequences of physical, demographic as well as overall environmental changes on the stability and persistence of populations. Here, we examine spatial and temporal genetic variation within and among barley landrace samples collected over a period of four decades (1976-2017),...

Effects of protected areas on welfare of local households: the case of Maasai Mara National Reserve in Kenya

Ayub M.O. Oduor, Dagne Mojo, Chao Fu, Yunli Bai, Huaping Long, Guoqin Wang & Linxiu Zhang
Protected areas are vital for biodiversity conservation although some have been criticized for not providing adequate socio-economic benefits to local people. However, empirical studies on socio-economic impacts of protected areas that control for confounding factors are rare. Here, we assessed the potential impacts of Maasai Mara National Reserve in South-Western Kenya on welfare (indicated by levels of income, consumption, and assets) of, and poverty incidence among 423 randomly selected local households. We used descriptive statistics...
