Prioritizing Crop Wild Relatives Collecting

  1. 1. Identifying conservation priorities for crop wild relatives Nora P. Castañeda-Álvarez, Colin K. Khoury, Harold A. Achicanoy, Vivian Bernau, Hannes Dempewolf, Ruth J.

  4. 4. CWR in genebanks: How much is enough?
  5. 5. How much is enough? Our process Density of seed collections Areas where gaps exist in ex situ collections for multiple taxa Density of records Ramírez-Villegas, J., Khoury, C., Jarvis, A., Debouck, D.G., Guarino, L., 2010. A gap analysis methodology for collecting crop genepools: A case study with Phaseolus beans. PLoS ONE 5, e13497.
  6. 6. Determine gaps in collections Model distributions Gather taxonomic data Gather occurrence data Make collecting recommendations Georeferencing Taxonomic Geographic Ecological How much is enough? Our process
  7. 7. Our process Definition of crops and crop wild relative taxa to analyze: • 81 crop genepools globally important for food security. • 1079 crop wild relative taxa (GP1 and GP2 + less closely related taxa with proven and potential uses in breeding) Vincent, H. et al. Biological conservation. 167, 265-275 (2013)
  8. 8. Our process Gathering and curating occurrence data from 420 data sources • Data quality check
  9. 9. Our process Modelling the distribution of CWR • MaxEnt: modelling algorithm • 19 climatic variables • 5 x 5km resolution • Native range of each taxa Measuring 3 gap analysis metrics • Sampling Representativeness Score • Geographic Representativeness Score • Ecological Representativeness Score Identifying collecting and conservation priorities Picture credit: https://scienceasaverb.wordpress.com/2010/10/29/introduction-to-ecological- niche-modeling-environmental-niche-modeling-species-distribution-modeling-part-two-what-is- niche-modeling/
