ELC for CWR

Mauricio Parra QuijanoEcogeographic land characterization for CWR diversity and gap analysis Training workshop 26–27 February 2014, Room UG08, Learning Centre, University of Birmingham

Diversity assessment and gap analysis

ELC overview

It is a made-to-measure map according to researcher needs to discriminate adaptive scenarios within a work frame

≠ Abiotic adaptation

≠ Adaptive geneticdiversity

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?

Right now we have enough tools to achieve our own plant abiotic-adaptive maps thanks to

If you know

… the resulting abiotic adaptive scenarios …

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?

Why this approach works better for CWR?

Human influence (domestication)

Specific environmental adaptation

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
