Herbivore effects increase with latitude across the extent of a foundational seagrass
Climate change is altering the functioning of foundational ecosystems. While the direct effects of warming are expected to influence individual species, the indirect effects of warming on species interactions ...

Seagrass Abundance Predicts Surficial Soil Organic Carbon Stocks Across the Range of Thalassia testudinum in the Western North Atlantic
The organic carbon (Corg) stored in seagrass meadows is globally significant and could be relevant in strategies to mitigate increasing CO2 concentration in the atmosphere. Most of that stored Corg is in the soil...

Status and Trajectories of Soft-Bottom Benthic Communities of the South Florida Seascape Revealed by 25 Years of Seagrass and Water Quality Monitoring
Although seagrass ecosystems are valued for the services they provide, anthropogenic impacts have led to global declines in seagrass area. South Florida harbors one of the most extensive and iconic seagrass la...

Decomposition Rates of Surficial and Buried Organic Matter and the Lability of Soil Carbon Stocks Across a Large Tropical Seagrass Landscape
The paradigm for understanding the accumulation of organic carbon in vegetated coastal “blue carbon” habitats holds that burial of organic carbon (Corg) slows decomposition and leads to stability of carbon stocks...

Open AccessSusan Lynn Williams: the Life of an Exceptional Scholar, Leader, and Friend (1951–2018)
Susan Lynn Williams (1951–2018) was an exceptional marine ecologist whose research focused broadly on the ecology of benthic nearshore environments dominated by seagrasses, seaweeds, and coral reefs. She took ...

Assessment of Hurricane Irma Impacts on South Florida Seagrass Communities Using Long-Term Monitoring Programs
Hurricanes are some of the largest environmental drivers of change in coastal systems. We investigated the impacts of Hurricane Irma on benthic macrophyte communities in Florida Bay (FB) and the Florida Keys N...

Article
Open AccessThe future of Blue Carbon science
The term Blue Carbon (BC) was first coined a decade ago to describe the disproportionately large contribution of coastal vegetated ecosystems to global carbon sequestration. The role of BC in climate change mi...

Decadal Monitoring in Bermuda Shows a Widespread Loss of Seagrasses Attributable to Overgrazing by the Green Sea Turtle Chelonia mydas
The condition of seagrass habitat and the marine environment on the Bermuda Platform, a mid-oceanic shallow water habitat in the northwest Atlantic, has been monitored since 2006. The overall oceanic climate o...

Article
Historical seagrass abundance of Florida Bay, USA, based on a foraminiferal proxy
A foraminiferal proxy for seagrass abundance was developed, tested and used to construct a record of seagrass variability for Florida Bay, USA, since its initial flooding ~ 3800 cal years BP. Of 76 species rec...

Does Nutrient Availability Regulate Seagrass Response to Elevated CO2?
Future increases in oceanic carbon dioxide concentrations (CO2(aq)) may provide a benefit to submerged plants by alleviating photosynthetic carbon limitation. However, other environmental factors (for example, nu...

Article
Ontogenetic diet shifts of green sea turtles (Chelonia mydas) in a mid-ocean developmental habitat
Green sea turtles (Chelonia mydas) arrive on the geographically isolated Bermuda platform as small juveniles and remain until they are approaching sexual maturity, at which point individuals depart for distant fe...

Chapter
The Role of Consumers in Structuring Seagrass Communities: Direct and Indirect Mechanisms
were traditionally assumed to be structured by competition as well as by “bottom up forces” such as resource availability and disturbance. However, a wealth of new evidence demonstrates that exertion of “...

Article
Fertilization Changes Seagrass Community Structure but not Blue Carbon Storage: Results from a 30-Year Field Experiment
Seagrass ecosystems are attracting attention as potentially important tools for carbon (C) sequestration, comparable to those terrestrial and aquatic ecosystems already incorporated into climate change mitigat...

Article
Predators help protect carbon stocks in blue carbon ecosystems
This Perspective considers the influence of marine predators on carbon cycling in salt marshes, seagrass meadows, and mangroves, and the potential role that these carbon-rich vegetated coastal ecosystems could...

Article
Effects of in situ CO2 enrichment on the structural and chemical characteristics of the seagrass Thalassia testudinum
Seagrasses commonly display carbon-limited photosynthetic rates. Thus, increases in atmospheric pCO2, and consequentially oceanic CO2(aq) concentrations, may prove beneficial. While addressed in mesocosms, these ...

Chapter
Introduction to Bermuda: Geology, Oceanography and Climate
The Bermuda islands and shallow platform lie on the top of an extinct Meso-Cenozoic volcano. The islands and the Bermuda Platform were created by reef building corals, vermetid snails and calcareous algae that...

Article
Stoichiometry, growth, and fecundity responses to nutrient enrichment by invertebrate grazers in sub-tropical turtle grass (Thalassia testudinum) meadows
Although the effectiveness of herbivores in mitigating the effects of nutrient enrichment is well documented, few studies have examined the effects of nutrient enrichment on components of consumer fitness. Enc...

Seagrass ecosystems as a globally significant carbon stock
The protection of organic carbon stored in forests is considered as an important method for mitigating climate change. Like terrestrial ecosystems, coastal ecosystems store large amounts of carbon, and there a...
