ELC for CWR Diversity assessment and gap analysis Mauricio Parra Quijano Ecogeographic land characterization for CWR diversity and gap analysis Training workshop 26–27 February 2014, Room UG08, Learning Centre, University of Birmingham
ELC overview It is a made-to-measure map according to researcher needs to discriminate adaptive scenarios within a work frame ≠ Abiotic adaptation ≠ Adaptive genetic diversity
ELC overview How to delineate different adaptive scenarios in a work frame?
ELC overview How in the past most of these type of maps were delineated? DMEER - EEA, 2003
ELC overview But what about abiotic masked conditions related to plant physiology-adaptation?
ELC overview Right now we have enough tools to achieve our own plant abioticadaptive maps thanks to Geographic Information Systems and…

If you know … the resulting abiotic adaptive scenarios … Your data Species data 3 0 1 1 3 8 1 2 0 1 0 1 1 5 0 1 and you also know the total possible scenarios for the target species (from known populations)
In situ gap analysis … from an ecogeographical point of view, are you including key populations in your protected areas? Species data Pops in situ conservation 1 0 8 2 2 2 1 0 1 0 5 1 1 0
In situ gap analysis … are you including key adaptive scenarios in your protected areas? in situ conservation X X
Why this approach works better for CWR? … it’s about time Human influence (domestication) Specific environmental adaptation
Ecogeographic Land Characterization Maps For ex situ conservation can be used as a base of: Massive/fast ecogeographic germplasm characterization Representativeness assessment in germplasm collections Core collections And complement of other interesting methods such as: Optimized germplasm collection FIGS
Ecogeographic Land Characterization Maps For in situ conservation this methodology has been used only as a criterion in studies to: Identify populations with high priority to be conserved Identify protected areas which contain target environments / are covering priority populations Determine optimal places for genetic reserves Establish CWR national strategies Prioritize sites to focus on on-farm conservation efforts
