“…Conversely, periods of high rainfall, watershed discharge and nutrient inputs from the watershed can be associated with lower peak phytoplankton biomass levels due to short water residence times. Similar relationships have been observed in two other ecosystems in Florida, the Guana, Tolomato, Matanzas estuary 41,74,75 and Lake George 17,76 . In both ecosystems the strong hurricane seasons of 2004 and 2005 yielded www.nature.com/scientificreports www.nature.com/scientificreports/ reduced peaks in phytoplankton biomass due to reduced water residence times, despite elevated concentrations of nutrients.…”

future increases in the intensity of hurricanes and el niño periods predicted by climate change models have focused attention on their role in stimulating harmful algal blooms (HABs). A series of hurricanes that recently impacted florida (USA) provided a unique opportunity to explore the relationships between hurricanes, el niño and HABs in two florida estuaries subject to repeated intense ecosystem disruptive HABs, the indian River Lagoon and the St. Lucie estuary. the roles that hurricanes and el niño play in contributing to HAB events are examined in the context of key structural and functional features of each estuary and their watersheds, including morphology, water residence time and hydrology, such as the influence of Lake Okeechobee discharges into the St. Lucie Estuary. The most direct impact was the increase in rainfall associated with hurricanes and el niño, resulting in enhanced nutrient loads which drive HABs in the indian River Lagoon and Lake okeechobee. Major HABs in Lake okeechobee also present an indirect threat of freshwater HAB blooms in the St. Lucie estuary via mandated discharges from the lake into the estuary during high rainfall periods. conversely, during the absence of HABs in Lake okeechobee, short water residence times produced by discharges into the St. Lucie estuary can result in lower bloom intensities.

“…Some of these divergent trends were associated with El Niño and La Niña periods, such as the major El Niño of 1997, and the extended La with storm events, such as the late summer storm of 1999 and the severe hurricane seasons of 2004 and 2005, which directly impacted the east coast of Florida (Steward et al 2006;Dix et al 2008). There were regional differences in the response of salinity to changes in rainfall.…”

This paper describes the results of 10 years of water quality monitoring in the Indian River Lagoon Florida, with special emphasis on the relationships between trends in climatic conditions and the distribution, composition, and abundance of the phytoplankton community. The Indian River Lagoon, which spans 220 km of Florida's east coast, is a region of particular concern because of the rapid rate of human development throughout the region and the hydrologically restricted character of the lagoon, which heightens the potential for algal bloom. Water sampling was carried out on a monthly to twice-monthly basis at six sites located in the northern and central lagoon. The 10-year study included both extended periods of below and above average rainfall. A number of ecologically distinct regions exist within the lagoon, which differ considerably in water exchange properties and watershed inputs. The northern lagoon is characterized by longer water residence times, lower phosphorus concentrations, higher nitrogen concentrations, and more stable salinity conditions than the central lagoon. Mean phytoplankton biovolumes were substantially higher at the sites in the northern lagoon than at the sites in the central lagoon, and algal blooms were more common and intense in the former region. Inter-annual patterns of phytoplankton biovolume were also different in the northern and central lagoon. In the northern lagoon, phytoplankton biovolumes were lowest during the drought period, from the autumn of 1998 to the spring of 2001. By contrast, algal bloom events in the central lagoon were not only less frequent but were not tied to periods of high rainfall. The most widespread and common bloom formers were the potentially toxic dinoflagellate Pyrodinium bahamense var. bahamense and two centric diatoms, Dactyliosolen fragilissimus and Cerataulina pelagica. Many of the biovolume peaks observed over the study period were attributable to these three species. The results of time series modeling of phytoplankton dynamics further highlighted the disparities between the two regions of the lagoon in terms of the suite of parameters that best predict the observed trends in the biomass of phytoplankton. Overall, the outcome of this initial modeling effort in the Indian River Lagoon suggests that time series approaches can help define the factors that influence phytoplankton dynamics.

“…In the year following these storms, several studies examined the damage to Florida's coastal ecosystems (e.g., Lapointe et al 2006, Paperno et al 2006, Ridler et al 2006, Sallenger et al 2006, Steward et al 2006, Tomasko et al 2006, Wang and Horwitz 2007, Dix et al 2008, Carlson et al 2010). These studies found spatial variation in the amount of physical damage sustained by coastal environments and the resident flora and fauna (Greening et al 2006).…”

Nutrient enrichment intensifies hurricane impact in scrub mangrove ecosystems in the Indian River Lagoon, Florida, USA

Abstract. Mangroves are an ecological assemblage of trees and shrubs adapted to grow in intertidal environments along tropical, subtropical, and warm temperate coasts. Despite repeated demonstrations of their ecologic and economic value, multiple stressors including nutrient over-enrichment threaten these and other coastal wetlands globally. These ecosystems will be further stressed if tropical storm intensity and frequency increase in response to global climate changes. These stressors will likely interact, but the outcome of that interaction is uncertain. Here, we examined potential interaction between nutrient over-enrichment and the September 2004 hurricanes. Hurricanes Frances and Jeanne made landfall along Florida's Indian River Lagoon and caused extensive damage to a long-term fertilization experiment in a mangrove forest, which previously revealed that productivity was nitrogen (N) limited across the forest and, in particular, that N enrichment dramatically increased growth rates and aboveground biomass of stunted Avicennia germinans trees in the interior scrub zone. During the hurricanes, these trees experienced significant defoliation with three to four times greater reduction in leaf area index (LAI) than control trees. Over the long term, the þN scrub trees took four years to recover compared to two years for controls. In the adjacent fringe and transition zones, LAI was reduced by .70%, but with no differences based on zone or fertilization treatment. Despite continued delayed mortality for at least five years after the storms, LAI in the fringe and transition returned to pre-hurricane conditions in two years. Thus, nutrient over-enrichment of the coastal zone will increase the productivity of scrub mangroves, which dominate much of the mangrove landscape in Florida and the Caribbean; however, that benefit is offset by a decrease in their resistance and resilience to hurricane damage that has the potential to destabilize the system.
