Genetic diversity of the black mangrove ( Avicennia germinans L.) in Colombia
This study analyzed the genetic diversity and patterns of genetic structure in Colombian populations of Avicennia germinans L. using microsatellite loci. A lower genetic diversity was found on both the Caribbean (Ho = 0.439) and the Pacific coasts (Ho = 0.277) than reported for the same species in o...

| description | This study analyzed the genetic diversity and patterns of genetic structure in Colombian populations of
Avicennia germinans L. using microsatellite loci. A lower genetic diversity was found on both the Caribbean (Ho
=
0.439) and the Pacific coasts (Ho
=
0.277) than reported for the same species in other locations of Central American Pacific, suggesting the deterioration of genetic diversity. All the populations showed high inbreeding coefficients (0.131–0.462) indicating heterozygotes deficience. The genetic structure between the Colombian coasts separated by Central American Isthmus was high (
F
RT
=
0.39) and the analyses of the genetic patterns of
A. germinans revealed a clear differentiation of populations and no-recent gene flow evidence between coasts. Genetic structure was found within each coast (
F
ST
=
0.10 for the Caribbean coast and
F
ST
=
0.22 for the Pacific coast). The genetic patterns along the two coasts appear to reflect a forcing by local geomorphology and marine currents. Both coasts constitute a different Evolutionary Significant Unit, so we suggest for future transplantations plans that propagules or saplings of the populations of the Caribbean coast should not be mixed with those of the Pacific Colombian coast. Besides, we suggest that reforestation efforts should carefully distinguish propagules sources within each coast. |
