Genetic and morphological variation of East Florida black mangrove (Avicennia germinans).

Mangroves are intertidal foundation species that influence both ecosystem function and associated community structure. Mangrove encroachment into temperate salt marsh has been documented worldwide, including along the East coast of Florida. Black mangrove (Avicennia germinans) currently occupy the northernmost range edge of all Florida mangrove species and are projected to experience further range expansion in the future. We present preliminary findings of our assessment of both genetic and morphological variation among ten A. germinans populations that encompass this species’ East Florida range, using a combination of microsatellite molecular markers and functional leaf traits. The results of this study provide baseline information on East Florida A. germinans population structure and contribute to our understanding of the potential impacts a shift from salt marsh to mangrove dominance may have on Florida coastal ecosystems.
