Abstract
To quantify the effect on genetic diversity of restoringtree populations in an area under the influence of an urban heatisland, we evaluated the genetic diversity of 72 Ceiba aesculifoliaindividuals, from a restoration experiment established from 2170to 2260 m a.s.l. Reintroduced individuals were compared with theprovenance from which the seeds were obtained, and two externalprovenances, for a total of 123 individuals. Samples were analyzedwith three AFLP primer combinations. Polymorphisms of 38.4 to62.5% were obtained. Genetic diversity estimated with the Simpsonindex ranged from 0.14 to 0.2. The provenances in the restorationsite had higher diversity than the provenance that originated theseeds. Groups formed with provenances with similar genetic diversity(no statistical differences) also shared similar Bayesian mixtureproportions. Having higher genetic diversity in restored provenancesthan in the provenance that originated the seeds can be favorable asthe conditions in the site change in the future due to the expectedincrease in the urban heat island effect as the nearby city expands.
期刊介绍:
Phyton-International Journal of Experimental Botany is an international journal that publishes on the broadest aspects of plant biology and ecology. The journal welcomes the original and exciting submissions that provide new and fundamental insights into the origins, development, and function of plants from the molecular to the whole organism and its interactions within the biotic and abiotic environment. Phyton-International Journal of Experimental Botany publishes outstanding research in the plant and ecology sciences, especially in the areas of plant physiology and biochemistry, plant metabolism, plant ecology and evolution, as well as those making use of synthetic, modeling, bioinformatics, and -omics tools. Manuscripts submitted to this journal must not be under simultaneous consideration or have been published elsewhere, either in part or in whole.
