Abstract

ABSTRACT Five populations of the invasive species Limnoperna fortunei were studied using polymorphic molecular (nine allozyme loci) and morphological (11 traits) markers in order to understand the patterns of genetic and morphological variability, structure and dispersion dynamics of this species in South America. High levels of genetic variability were found in South American invasive populations, and significant deviations from the Hardy-Weinberg proportions clearly indicated that the invasion process is still under way, probably by means other than natural migration.

南美入侵Limnoperna fortunei (Dunker, 1857)种群的高水平遗传和形态变异

摘要利用多态分子（9个等位酶基因座）和形态（11个性状）标记对入侵物种火绒花的5个种群进行了研究，以了解该物种在南美洲的遗传和形态变异模式、结构和扩散动态。在南美洲入侵种群中发现了高度的遗传变异性，与Hardy-Weinberg比例的显著偏差清楚地表明，入侵过程仍在进行中，可能是通过自然迁徙以外的方式。
