title: Incorporating evolutionary and threat processes into crop wild relatives conservation

description: Crop wild relatives (CWR) intra- and interspecific diversity is essential
 for crop breeding and food security. However, intraspecific genetic
 diversity, which is central given the idiosyncratic threats to species in
 landscapes, is usually not considered in planning frameworks. Here, we
 introduce an approach to develop proxies of genetic differentiation to
 identify conservation areas, applying systematic conservation planning
 tools that produce hierarchical prioritizations of the landscape. It
 accounts for: (i) evolutionary processes, including historical and
 environmental drivers of genetic diversity, and (ii) threat processes,
 considering taxa-specific tolerance to human-modified habitats, and their
 extinction risk status. Our results support the development of national
 strategies for the conservation and use of CWR in Mexico and inform public
 policy to mitigate threat processes to CWR. Although we focus on
 Mesoamerican CWR within Mexico, our methodology offers opportunities to
 effectively guide conservation and monitoring strategies to safeguard the
 evolutionary resilience of any taxa, including in regions of complex
 evolutionary histories and mosaic landscapes.
description: We applied a modified version of a planning framework for CWR conservation including CWR checklist, CWR inventory, taxa extinction risk assessment and a systematic conservation planning assessment. The first three steps are thoroughly described in Goettsch et al. (https://doi.org/10.1002/ppp3.10225). Here, we focus on the systematic conservation planning assessment, introducing an approach in order to identify conservation areas for CWR that account for genetic differentiation in a spatially explicit way, through the use of proxies of genetic differentiation. <br><br>The data presented here includes Zonation input and output files, habitat rasters, Table with IUCN category per taxa, metadata, and genetic data used for the conservation planning assessment and figures. The genetic data used to validate our findings belongs to a maize wild relative, the teosinte <em>Zea</em> <em>mays</em> subsp. <em>parviglumis</em>. Raw genetic data was produced by a different study (Ph.D. thesis Rivera-Rodríguez, D. M. Estudio de la Diversidad y Estructura Genómica del Teocintle. Doctoral Thesis, Advisor: Sánchez, J.J., Universidad de Guadalajara, 2018) and it is available elsewhere (Rivera-Rodríguez under review). Here, the admixture and plink files used for the analyses of this paper are provided.<br><br>Code used to process and analyse the data is available at https://github.com/CONABIO/analisisUniCons_proxiGen
description: The data set includes raster files (.tiff), text files (.csv,
 .txt), Admixture output files (.Q) and plink files (.fam, .bed, .bim) that
 are meant to be used with Zonation, R, and GIS software such as ArcMap or
 QGis. <br><br>In this data repository, related files used
 together for analyses are compressed in a .zip or .tar.gz file (for larger
 files that needed more compression).<br><br>Code used to
 process and analyse the data is available at https://github.com/CONABIO/analisisUniCons_proxiGen. Release: Mastretta-Yanes, Alicia, Tobón-Niedfeldt, Wolke, & Cuervo-Robayo, Angela P. (2022).
