Vegetation survey of southwest Florida for use in assessment of the Picayune Strand Restoration Project effects This release consists of vegetation data collected across an environmental gradient at Ten Thousand Islands National Wildlife Refuge (TTI NWR) near Naples, Florida, USA. The refuge is within the impact area of the Picayune Strand Restoration Project (PSRP), a large-scale hydrologic restoration project in southwest Florida that was authorized by the U.S. Congress in 2007. Vegetation transects were located in the following wetland types on the refuge: brackish marsh, salt marsh, and transition marsh. Data from vegetation transects established in nearby areas outside of the PSRP impact area, in Fakahatchee Strand Preserve State Park (FSPSP) and Big Cypress National Preserve (BICY), are also included. The study spanned... Categories: Data; Tags: Big Cypress National Preserve, Botany, Brackish Marsh, Copeland, Ecology, All tags...

These species shifts have been attributed primarily to rising sea levels and warming winter temperatures, but the role of elevated atmospheric carbon dioxide (CO2) and water availability may become more prominent drivers of species interactions under future climate conditions. In this greenhouse study we examined the effects of CO2 concentration (ambient, elevated) and water regime (drought, saturated, flooded) on early growth of the mangrove species Avicennia germinans and Spartina alterniflora, a herbaceous grass.

USA, biota, Fewer tags Soil surface elevation dynamics in a mangrove-to-marsh ecotone characterized by vegetation shifts This release consists of soil surface elevation, also called vertical land motion of the wetland (VLMw), and vertical accretion data collected over time across an environmental gradient at Ten Thousand Islands National Wildlife Refuge near Naples, Florida, USA. VLMw was measured using rod surface elevation tables, while accretion was measured using feldspar marker horizons (i.e., RSET-MH technique). Stations were located in the following wetland types: brackish marsh, salt marsh, transition marsh, and mangrove forest. Vegetation cover in the vicinity of the RSET-MH stations was described. The study spanned six years, from 2011 to 2017. Categories: Data; Tags: Botany, Ecology, Estuarine ecosystems, Naples, Florida, Ten Thousand Islands National Wildlife Refuge, All tags...

Vegetation cover was estimated in permanent plots, and soil cores were collected for determination of bulk density, organic matter content and texture. VLMw was measured using rod surface elevation tables, while accretion was measured using feldspar marker horizons (i.e., RSET-MH technique).

Understanding the ecological influence of macroclimatic drivers is important because it provides a foundation for anticipating the effects of climate change. Tidal saline wetlands include mangrove forests, salt marshes, and salt flats, which occupy similar geomorphic settings but different climatic regimes. However, most global- or regional-scale analyses have treated these wetlands as independent systems. Here we used climate and literature-derived ecological data from all three systems, collected across targeted regional-scale macroclimatic gradients, to test hypotheses...
