AbstractThe newly discovered endemic maple Acer yangbiense of China has only five individuals left in the wild, and thus has been classified as a plant species with extremely small populations (PSESP). PSESP species call for emergency protection procedures, such as ex-situ conservation and reintroduction. Our objectives were to examine the genetic diversity of A. yangbiense and to evaluate former conservation strategies from a genetic point of view. Our results suggested that A. yangbiense was not genetically depauperate, but its genetic loss at a species level was obvious. A parentage analysis indicated a high selfingrate in A. yangbiense and suggested the existence of a previously unknown wild individual. Former conservation strategies did not include all genetic variations of the wild population, and gene diversity of the ex-situ conserved seedlings is lower than that of the wild population. From our findings, we make suggestions to guide the subsequent protection of this species. (C) 2015 Elsevier Ltd. All rights reserved.
