Research Progress and Conservation Status of the Rare and En-dangered Abies yuanbaoshanensis
摘要
Abstract
Abies yuanbaoshanensis is a critically endangered(CR)relict species of the Pinaceae family endemic to China.There are 802 existing wild adult individuals,and the population presents a declining structure dom-inated by old trees.This article systematically reviews the research progress and current protection status of A.yuanbaoshanensis in recent years.In terms of biological and reproductive characteristics,this tree species exhibits typical coniferous tree morphology,requires humid and cold habitats,and has extremely weak repro-ductive capacity with a long fruiting cycle accompanied by mast seeding.Ecologically,the population shows a declining age structure(dominated by old trees and scarce in juveniles).Its spatial distribution is transitio-ning from clumped to uniform.The community is primarily coniferous-broadleaved mixed forest,and seedling regeneration is better in forest gaps than under closed canopy.Genetically,the population possesses low ge-netic diversity and a high inbreeding rate,with a single chloroplast haplotype,leading to limited adaptive po-tential.In terms of endangered mechanisms,its endangerment results from the synergistic effects of internal and external factors.External factors include climate warming,habitat fragmentation and human disturbance,while internal factors involve inherent regeneration barriers and low genetic diversity.At present,the conser-vation of A.yuanbaoshanensis mainly relies on in situ conservation and artificial propagation.Nevertheless,multiple challenges remain,including insufficient systematic research,prominent bottlenecks in propagation techniques,and a lack of interdisciplinary collaboration.In the future,studies on genomics,reproductive phys-iology and community dynamics need to be integrated,and habitat restoration together with genetic resource management should be carried out to enhance the population's recovery potential.关键词
