  • Why Gap Analysis?
    • CG collections suffer from both over- and under- collecting
    • Duplications increase costs
    • But also significant gaps in the collections
  • Why Gap Analysis?
    • Tool to assess crop genetic and geographical diversity.
    • Allows detecting non-fulfilled species collections as well as defining which species should be collected and where these collections should be focused.
    • Assesses the current extent at which the ex situ conservation system is correctly holding the genetic diversity of a particular genepool.
  • The Gap Analysis pathway Taxonomy review Data gathering Georeferentiaton Environmental data gathering Gap Analysis process Final recommendations
  • The Gap Analysis process
    • Proxy for:
    • Range of traits
    • Proxy for:
    • Diversity
    • Possibly biotic traits
    • Proxy for:
    • Abiotic traits
    • Identifying gaps
    Geographic dimension Environmental dimension Taxonomic dimension
  • Taxa priorization High Priority Taxa Medium Priority Taxa Low Priority Taxa No conservation required
  • The Rugosi and Acutifolii case
    • Section Acutifolii
      • P. acutifolius
      • P. acutifolius var. acutifolius
      • P. acutifolius var. latifolius
      • P. acutifolius var. tenuifolius
      • P. parvifolius
    • Section Rugosi
      • P. angustissimus
      • P. filiformis

  • Prioritization results
  • High Priority Taxa (HPT)
    • Where to find the most?
  • High Priority Taxa (HPT)
    • HPT for Rugosi and Acutifolii
    P. carteri Section: Rugosi P. acutifolius var. latifolius Section: Acutifolii
    • HPT and Protected Areas
  • High Priority Taxa (HPT)
    • HPT and Protected Areas
  • Are there analyses for other crops?
    • 13 crop genepools analyzed, 7 analyses in the pipeline
    • Recommendations on which taxa are priority to conserve
    • Maps indicating what and where to collect
    • Results publicly available at:
  • Taxon-level and genepool level priorities
  • Methodology and code Methodology Code
  • Priorities list per genepool
  • Georeferenced datasets
  • Gap Analysis
