Macroalgal blooms in coastal lagoons of the Gulf of California eco-region: a summary of current knowledge

The role of submerged macrophytes and macroalgae in nutrient cycling: A budget approach

“…Under the closed mouth state the nutrients in river water passing the head of the estuary at the weir will not reach the lower end of the system and it is therefore expected that the lower reaches become benthic driven with respect to nutrient input. Pinon-Gimate et al (2012) noted that 'new' nutrients arriving from external inputs were not the only sources that controlled macroalgal growth and that recycling from the benthos also played a major role. Research on the growth of Ulva spp.…”

The takeover of Thalassia testudinum by Anadyomene sp. at Biscayne Bay, USA, cannot be simply explained by competition for nitrogen and phosphorous

“…The input of high loads of nutrients into coastal waters is mainly a consequence of anthropogenic activities such as fertilization, wastewater discharges and fossil fuel combustion, and constitutes a global threat to marine life (Vitousek 1997, McGlathery 2001, Kemp et al 2005, Howarth 2008). The high nutrient levels may stimulate the development of opportunistic fast-growing macroalgae species (Valiela et al 1997, Bricker et al 2003, Lapointe et al 2005, Piñón-Gimate et al 2012, Ye et al 2011, which may outcompete seagrasses and cause a shift from clear-water, oligotrophic seagrass-dominated systems to turbid, eutrophic seaweed-dominated systems (Burkholder et al 2007). The most common mechanism for seagrass decline under nutrient enrichment is light reduction.…”

Evaluation of the Quality of Coastal Ecosystems in the Spermonde Archipelago Using Macroalgae as Indicators

“…Besides, this station also receives a supply of nutrients through the household liquid waste stream. Anthropogenic activity on land increases the supply of nutrients for coastal eutrophication that can be achieved in Coastal eutrophication [33,34].…”
