“…No records are available on the pre-or post-impoundment vegetation in this area (Rey et al 1986). Impounding, which involved construction of a dike around a wetland with material excavated from the perimeter to control flooding and water depth, altered the wetland's hydrology and pore water chemistry (Carlson et al 1983;Rey et al 1986Rey et al , 1990Rey et al , 1992. In MI 23, water connection for exchange and circulation with the IRL is through the breach and two 30" diameter culverts (James David, unpublished data).…”

The objectives of this study were to determine effects of nutrient enrichment on plant growth, nutrient dynamics, and photosynthesis in a disturbed mangrove forest in an abandoned mosquito impoundment in Florida. Impounding altered the hydrology and soil chemistry of the site. In 1997, we established a factorial experiment along a tree-height gradient with three zones, i.e., fringe, transition, dwarf, and three fertilizer treatment levels, i.e., nitrogen (N), phosphorus (P), control, in Mosquito Impoundment 23 on the eastern side of Indian River. Transects traversed the forest perpendicular to the shoreline, from a Rhizophora mangle-dominated fringe through an Avicennia germinans stand of intermediate height, and into a scrub or dwarf stand of A. germinans in the hinterland. Growth rates increased significantly in response to N fertilization. Our growth data indicated that this site is N-limited along the tree-height gradient. After 2 years of N addition, dwarf trees resembled vigorously growing saplings. Addition of N also affected internal dynamics of N and P and caused increases in rates of photosynthesis. These findings contrast with results for a R. mangle-dominated forest in Belize where the fringe is N-limited, but the dwarf zone is P-limited and the transition zone is co-limited by N and P. This study demonstrated that patterns of nutrient limitation in mangrove ecosystems are complex, that not all processes respond similarly to the same nutrient, and that similar habitats are not limited by the same nutrient when different mangrove forests are compared.

“…Jennings and Williams (1992) concluded that this species probably originated from Satellite Beach in Brevard County and prefers brackish backwater habitats with a mucky, organic substrate. This habitat type is typical of the perimeter ditch of RIM impoundments (Rey et al 1992). Not surprisingly, blackchin tilapia have recently been collected within several impounded and non-impounded mangrove ecosystems adjacent to the IRL (Faunce 1995, Taylor et al 1998.…”

The spatial and temporal dynamics of the ichthyofauna within a seasonally impounded mangrove ecosystem were studied through biweekly daylight seining, Indices for assemblage structure showed low values in winter months and high values in April and May. The species assemblages differed markedly by site and with season. Abiotic factors had an affect on the ichthyofauna; abundance was inversely related to water level, whcreas species composition was weakly related to salinity. The 41 species collected were common to Florida, USA mangrove communities, with the important exception of blackchin tilapia Tilapia melanotheron. This exotic species was the second most abundant in terms of overall catch, and its presence represents a significant change from previous ichthyofaunal surveys from impounded mangrove/saltmarsh habitats. Blackchin tilapia constituted over 90% of biomass estimates in winter, when the entire iehthyofauna was concentrated in the deeper areas of the system. The impoundment of mangrove ecosystems in Florida has created an abundant network of preferred habitats for blackchin tilapia. The impact of this species on the native fauna is unclear and deserves further study.

“…Such variability has been amply documented for impounded and unimpounded coastal wetlands in Florida (Brockmeyer et al 1997), including some of the same sites used in the study and for some of the same or related variables including pore water chemistry (e.g. Carlson et al 1983, Rey et al 1992, Feller et al 2003; fishes, macroinvertebrates, and plankton (e.g. Gilmore et al 1982, Gilmore 1987, Rey et al 1990c,d, 1991, Vose & Bell 1994, Taylor et al 1998, Feller et al 2003, Stevens et al 2006; soils (e.g.…”

A recent study by Middleton et al. (2008; Mar Ecol Prog Ser 371:117-129) characterizing mangrove swamps impounded for mosquito control in Florida has a number of problems that weaken some of the resulting conclusions. We examine some of these issues, which we divide into (1) errors of fact, (2) methodological problems, (3) unwarranted conclusions. Errors of fact include incorrect historical assertions, incorrect site descriptions, and inaccurate statements on the general effects of impoundments. Methodological problems include inadequate sampling for the stated purpose, in particular using results of one-time sampling of very small marsh areas to characterize entire marshes and groups of marshes; defining inadequate controls; use of heterogeneous experimental treatment groups, including highly atypical and unrepresentative sites within experimental treatments; selective sampling; and others. Unwarranted conclusions include the characterization and comparison of marshes and management strategies based upon unrepresentative sampling, and the attribution of differences in habitat function as a result of management strategy without any experimental evidence to suggest such an effect. We make suggestions for mitigating some of these issues.
