Article
Full-text available
Nutrient enrichment is a major driver of environmental change in mangrove ecosystems. Yet, nutrient enrichment impacts on physiological processes that regulate CO2 and water fluxes between mangrove vegetation and the atmosphere remain unclear. We measured peak growing season photosynthesis (A) and respiration (R) in black mangrove (Avicennia germin...
Conference Paper
Full-text available
A one-day workshop was held in an effort to bring together local and statewide stakeholders to highlight priorities for clam restoration to move forward in the Indian River Lagoon, Florida. Breakout sessions emphasized research, management, and outreach priorities surrounding clam restoration in the Indian River Lagoon. The key findings are highlig...
Article
Full-text available
Coastal eutrophication is an issue of serious global concern and although nutrient subsidies can enhance primary productivity of coastal wetlands, they can be detrimental to their long-term maintenance. By supplying nutrients to coastal ecosystems at levels comparable to intensive agriculture practices, roosting colonial waterbirds provide a natura...
Article
Full-text available
Global climate change is driving the expansion of mangroves into saltmarsh habitat, which may alter the rate and magnitude of organic matter decomposition and nutrient cycling due to differences in the structural complexity, litter quality, and other ecophysiological traits of foundation species. This work quantified and compared aboveground litter...
Article
Human activities have led to 1–2% of coastal wetlands lost per year globally, with subsequent losses in ecosystem services such as nutrient filtering and carbon sequestration. Wetland construction is used to mitigate losses of marsh cover and services resulting from human impacts in coastal areas. Though marsh structure can recover relatively quick...
Article
Full-text available
In this paper, we present the highest-resolution-available (10 m) national map of the mangrove ecosystems of Belize. These important ecosystems are increasingly threatened by human activities and climate change, support both marine and terrestrial biodiversity, and provide critical ecosystem services to coastal communities in Belize and throughout...
Article
Full-text available
Mangrove ecosystems are important for carbon storage due to their high productivity and low decomposition rates. Waterways have experienced increased nutrient loads as a result of anthropogenic activities and it is unclear how this may affect carbon and nutrient cycles in downstream mangroves that receive these nutrient-rich waters. Using a laborat...
Article
Full-text available
Human activities have decreased global salt marsh surface area with a subsequent loss in the ecosystem functions they provide. The creation of marshes in terrestrial systems has been used to mitigate this loss in marsh cover. Although these constructed marshes may rapidly recover ecosystem structure, biogeochemical processes may be slow to recover....
Article
Full-text available
Climate change and nutrient enrichment are two phenomena impacting coastal ecosystems. In coastal wetlands, mangroves in temperate–tropical ecotones are encroaching on adjacent saltmarshes, a pattern that is primarily attributed to warmer winter temperatures. Climate change is also expected to increase the vulnerability of coastal wetlands to eutro...
Article
Full-text available
Mangroves sequester large quantities of carbon (C) that become significant sources of greenhouse gases when disturbed through land- use change. Thus, they are of great value to incorporate into climate change adaptation and mitigation strategies. In response, a global network of mangrove plots was established to provide policy-relevant ecological d...
Article
Full-text available
In North America, the dynamic ecotonal boundary between mangrove and salt marsh is currently fluctuating in response to freeze-free winters, which can cause rapid alterations in a number of wetland processes and attributes. Permanent plots were established in pure salt marsh habitat along the Atlantic coast of Florida in 2015, and by 2018, mangrove...
Article
Full-text available
Foundation plant species play an important functional role in modifying microenvironment through vegetation structure and by influencing soil properties. Mangroves and salt marsh differ in vegetation structure, yet offer similar ecosystem services. This work aimed to understand how different vegetation classes and abiotic factors along a latitudina...
Article
Full-text available
Across the globe, coastal wetland vegetation distributions are changing in response to climate change. In the southeastern United States, increased winter temperatures have resulted in poleward range expansion of mangroves into pure salt marsh habitat. Climate change-induced expansion of mangroves into salt marsh will significantly alter carbon (C)...

Simpson, L.T.; Osborne, T.Z., and Feller, I.C., 0000. Establishment and biomass allocation of black and red mangroves: Response to propagule flotation duration and seedling light availability. Global climate change is driving the expansion of mangroves into salt-marsh habitats around the world, and the ability of mangroves to displace salt marsh is...
Article
Full-text available
There are few detailed carbon (C) budgets of mangrove forests, yet these are important for understanding C sequestration in mangrove forests, how they support the productivity of the coast and their vulnerability to environmental change. Here, we develop C budgets for mangroves on the islands of Twin Cays, Belize. We consider seaward fringing fores...
Article
Full-text available
A field experiment in Florida's salt marsh-mangrove ecotone was conducted to determine the impact of nitrogen (N) addition and aboveground competition on mangrove seedling growth and biomass partitioning. At this ecotone, Avicennia germ mans (black mangrove) seedlings grow in competition with salt marsh species and provide a natural experiment. The...
