Fast Detection of Nutrient Limitation in Macroalgae and Seagrass with Nutrient-Induced Fluorescence
BACKGROUND Rapid determination of which nutrients limit the primary production of macroalgae and seagrasses is vital for understanding the impacts of eutrophication on marine and freshwater ecosystems. However, current methods to assess nutrient limitation are often cumbersome and time consuming. For phytoplankton, a rapid method has been described based on short-term changes in chlorophyll flu...
متن کاملExperimental Nutrient Enrichment Causes Complex Changes in Seagrass, Microalgae, and Macroalgae Community Structure in Florida Bay
We examined the spatial extent of nitrogen (N) and phosphorus (P) limitation of each of the major benthic primary producer groups in Florida Bay (seagrass, epiphytes, macroalgae, and benthic microalgae) and characterized the shifts in primary producer community composition following nutrient enrichment. We established 24 permanent 0.25m2 study plots at each of six sites across Florida Bay and a...
متن کاملExploring the spatio-temporal variation of seagrass ecosystems in southern Tampa bay
This paper presents the status and outcomes of our efforts in using developed coastal geospatial information technology for studying on seagrass degradation in Tampa Bay, FL, in the last period of our NSF-funded Digital Government project. The research results of the project in the first three years are summarized. In the fourth year, the project is focused on seagrass degradation monitoring an...
متن کاملMarine fisheries declines viewed upside down: human impacts on consumer-driven nutrient recycling.
We quantified how two human impacts (overfishing and habitat fragmentation) in nearshore marine ecosystems may affect ecosystem function by altering the role of fish as nutrient vectors. We empirically quantified size-specific excretion rates of one of the most abundant fishes (gray snapper, Lutjanus griseus) in The Bahamas and combined these with surveys of fish abundance to estimate populatio...
متن کاملMacro and micro nutrients of tropical seagrasses, Halophila ovalis, H. spinulosa and Halodule uninervis in Johore, Malaysia
The present study determined and compared contents of macro- (Nitrogen-N, Phosphorus-P, Potassium-K, Calcium-Ca, Magnesium-Mg) and micro- (Zinc-Zn, Iron-Fe, Manganese-Mn, Cupper-Cu) nutrients in four seagrass species big-leaved (BL) Halophila ovalis (R. Br.) Hook. f., small-leaved (SL) H. ovalis (R. Br.) Ascherson, H. spinulosa (R. Br.) Aschers. in Neumayer and Halodule uninervis (Forssk.) Asch...
