摘要: Abstract Rare plant reintroductions are designed to increase the number of individuals in wild, but can also improve genetic diversity populations, reducing both short-term and long-term extinction risks. We used microsatellites developed for genus Pseudophoenix H. Wendl. ex Sarg. determine how reintroduced plants endangered sargentii planted Florida Keys early 1990s contributes population structure species. sampled 108 representing wild populations from situ collection at Fairchild Tropical Botanic Garden. The stand on Elliott Key Long displayed evidence drift, inbreeding, decreased gene flow. In contrast, low inbreeding higher heterozygosity. All deviated significantly Hardy-Weinberg equilibrium. p...
