Nutrient Enrichment Increases Blue Carbon Potential of Subtropical Seagrass Beds. [PDF]

Glob Chang Biol
Seagrass beds have tremendous potential to mitigate climate change because their high rates of primary production bury large amounts of carbon. They are also globally threatened by nutrient pollution, and thus, realizing this potential requires understanding how this stressor affects carbon burial.

Seasonal behavior of Thalassia testudinum (Hydrocharitaceae) metabolites

Revista de Biología Tropical, 2016
The marine angiosperm Thalassia testudinum, commonly known as turtle grass, is a dominant seagrass that grows in the Caribbean Sea shelf associated to Syringodium filiforme. The hydroalcoholic extract of T. testudinum is rich in polyphenols; the most abundant metabolite in this extract is thalassiolin B, a glycosilated flavonoid with skin damage ...

Temperature Drives Seagrass Recovery Across the Western North Atlantic. [PDF]

Glob Chang Biol
In this study, we used field experiments across 23° of latitude (from Bermuda to Panama) to investigate how important climate change drivers impact the recovery rates of turtlegrass, a widespread marine plant. We found that both global (temperature) and local (grazing and nutrients) drivers affect seagrass recovery rates and thus resilience.

Nitrogen Fixation in Subtropical Seagrass Sediments: Seasonal Patterns in Activity in Santa Rosa Sound, Florida, USA

Journal of Marine Science and Engineering, 2021
Seagrass beds are important coastal habitats that are diminishing globally. Nitrogen, a key nutrient, often limits seagrass growth. Nitrogen fixation provides new, bioavailable nitrogen to the plants.

Experimental evidence of pollination in marine flowers by invertebrate fauna

Nature Communications, 2016
Marine plants reproduce by hydrophilly, that is, the movement of pollen by water. Here, the authors show that invertebrates can also carry pollen from male to female Thalassia testudinum plants.

Sea grasses, a new unreported habitat for the heterobranch mollusk Umbraculum umbraculum in the Caribbean region

Marine and Fishery Sciences, 2020
Herein, a new habitat for the heterobranch mollusk Umbraculum is described. One specimen was found on a Thalassia testudinum bed at Taganga Bay at 3 m depth, a buffer area of the Tayrona National Park, Colombian Caribbean.

Stress‐Resistant Symbiodiniaceae and Diverse Bacterial Communities Promote Coral Persistence in Variable, Multi‐Stressor Environments

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Corals living in multi‐stressor bays in Curaçao maintain stress‐tolerant symbiotic algae and specialized bacterial communities in comparison to those in nearby reefs. These findings provide insight into how Caribbean coral holobionts persist in extreme and marginal conditions and may respond under future environmental conditions.

Soil Carbon Stocks in Fijian Seagrass: Environmental Drivers, National Inventories, and Implications for Blue Carbon Accounting in Small Island Settings

Global Biogeochemical Cycles, Volume 40, Issue 5, May 2026.
Abstract Pacific island seagrass systems remain critically underrepresented in global blue carbon assessments despite their potential significance for climate mitigation. We present the first national‐scale assessment of seagrass soil carbon stocks for a Pacific island nation based on 135 sediment cores from 47 sites across Fiji.
