Abstract

Juglans pyriformis Liebm. (Juglandaceae) is a threatened and endemic tree that grows in the cloud forest of Mexico. Natural populations of this species have been reduced due to, among others, changes in land use, overexploitation, and logging, with probable effects on its genetic diversity and structure. To determine the levels of variation and genetic structure of two populations with different silvicultural regimes, six inter-simple sequence repeat (ISSR) primers were used to amplify DNA from 35 individuals from a high-logging population and 32 from a low-logging population. The results show a higher polymorphism in the low-logging population (81.5%) compared to the high-logging population (77.4%). The genetic differentiation coefficient (PhiPT) values (0.109), genetic distance (0.134) and STRUCTURE analysis (Fst = 0.2271, P = 0.04) show significant genetic differentiation between populations. Rare, private, and monomorphic bands were detected in both populations. These results confirm the trend of reduced genetic variation due to logging.

选择性采伐对梨形核桃遗传分化的影响。人口

梨状核。(Juglandaceae)是一种生长在墨西哥云雾林中的濒危特有树种。由于土地利用的变化、过度开发和伐木等原因，该物种的自然种群数量减少，可能对其遗传多样性和结构产生影响。利用6条ISSR (intersimple sequence repeat，简单序列重复)引物对35个高采伐种群个体和32个低采伐种群个体的DNA进行了扩增，以确定不同造林制度下两个种群的变异水平和遗传结构。结果表明，低采伐种群的多态性(81.5%)高于高采伐种群(77.4%)。遗传分化系数(PhiPT)值(0.109)、遗传距离(0.134)和结构分析(Fst = 0.2271, P = 0.04)表明群体间存在显著的遗传分化。在两个种群中均检测到罕见的、私有的、单态的条带。这些结果证实了由于采伐而减少遗传变异的趋势。
