An approach to genetic resources conservation of peripheral isolated plant populations: the case of an island narrow endemic species

摘要: This study reinforces the argument that forest genetic resources for peripheral isolated plant populations (PIPP) need to come under rationalistic assessment, developing and proposing conservation strategies of resources. Cedrus brevifolia is a narrow endemic island tree occurring in sole population. Using biparentally paternally inherited microsatellites, contribution variation patterns within sites (subpopulations) plantations this species were assessed. The C. population recorded uneven partition diversity at site local scales; mirroring demography evolutionary factors occurred long-term intra-species level. Results from imply screening rejection unsuitable seedlings before plantation establishment did not influence divergence planted trees general pool natural Based on these outcomes, numerous measures are proposed, towards maintaining species’ These ensure dynamic processes stands. Thus, argues PIPP which high non-uniform distribution viability (complex patterns), several small units seem be most units. In such case, micro-reserves (GMR) can enacted, where on-the-point situ activities adopted, while GMR could used ex purposes. conclusion, maintenance should regarded as one main prerequisites sustainable management survival species.
