BETA DIVERSITY PATTERNS AND DRIVERS ACROSS CONTRASTING COASTAL PLAIN WETLANDSCAPES
Geographically isolated wetlands (GIWs) are wetlands surrounded by uplands that lack persistent surface water inlets or outlets. Despite their infrequent surface water exchanges, GIWs exhibit various modes and frequencies of surface and subsurface flows over space and time. Differences in GIW connectivity and inundation patterns within wetlandscapes (i.e., wetland-rich landscapes) provide insight on the diversity of supported wetland functions. The provision of habitat for wetland flora and fauna is one such function, with wetlandscapes providing increased habitat heterogeneity and beta diversity (i.e., taxonomic dissimilarity) when their GIWs differ in hydrologic and geographic properties. To better understand differences in wetlandscape beta diversity, we selected 16 GIWs from across three Florida Coastal Plain wetlandscapes, surveyed vegetation and fishes twice annually between summer 2018 and spring 2020, and measured beta diversity for each taxonomic group. We also recorded wetland stage and collected biogeochemical measurements to assess the physical and chemical hydrologic influences on taxonomic dissimilarity using constrained ordination. Our results suggest informative differences in beta diversity patterns and drivers across taxonomic groups and wetlandscapes that shed light on dominant metacommunity processes and have implications for the conservation of GIW biota.
