Habitat Discontinuities Form Strong Barriers To Gene Flow Among Mangrove Populations, Despite The Capacity For Long Distance Dispersal [Dataset], Rachel M. Binks, Margaret Byrne, Kathryn Mcmahon, Georgina Pitt, Kathy Murray, Richard D. Evans

Mangrove forests are among the world’s most important ecosystems but are declining rapidly worldwide. Effective conservation management requires a better understanding of the patterns and drivers of gene flow across a range of spatial scales.

Despite the capacity for long distance propagule dispersal, field studies suggest that mangrove propagules tend not to disperse far from the release point, which has important implications for the impact of habitat discontinuities on gene flow. We use a comprehensive seascape genomics approach to investigate this concept in the world’s most widely distributed mangrove species, Avicennia marina.
