Crop wild relatives (CWR) are a rich source of genetic diversity for crop improvement. Combining ecogeographic and phylogenetic techniques can inform both conservation breeding. Geographic occurrence, bioclimatic, biophysical data were used to predict species distributions, range overlap niche occupancy in 36 taxa closely related sunflower (Helianthus annuus L.). Taxa lacking comprehensive ex situ identified. The predicted distributions Helianthus identified substantial overlap, asymmetry...
Of the countries considering national-level policies for incentivizing reductions in forest-based greenhouse gas emissions (REDD+), some 25 are experiencing (or emerging from) armed-conflicts. It has been hypothesized that outcomes of interactions between carbon-storage and peacebuilding efforts could result either improved or worsened forest conservation likewise increased decreased conflict. Hence, this study we explore potential efforts, with Colombia as a case study. Spatial associations...

Effective assessments of the current status biodiversity conservation are needed to support planning, policy and action, from local global levels. Of particular use would be well documented, reproducible methods based on openly accessible data tools. Such should provide an accurate estimate state diversity, identifying gaps in systems, while providing a benchmark against which measure success, including determining when goals have been met. Here we introduce GapAnalysis, open source R...
