[PCA] Article: Evolution of plant materials for ecological restoration

[Lindsey Riibe]

A new article on the consequences of intentional and/or inadvertent
evolutionary modification of restoration materials with respect to
population viability and ecosystem function.

*Evolution of plant materials for ecological restoration: insights from the
applied and basic literature  *(*Espeland, et al.*)

Erin K. Espeland (USDA‐ARS Pest Management Research Unit), et al.  review
studies from the evolutionary and agricultural literature "to illustrate
how changes in the amount and type of genetic variation in ex situ
repositories (source collections and production farms) could affect plant
performance in restoration."

The paper offers six practices to decreases the potential for unintentional
evolution and maladaptation which the authors refer to as * “evolutionarily
enlightened management”* - 1. multiple collections through time, 2.
multiple collections through space, 3. large effective population size, 4.
provenance tracking, 5. promoting gene flow, and 6. reducing selection.
