“…These methods are used to reduce dense stands of vegetation to create hemi-marsh conditions, to promote plant species that provide seeds eaten by waterfowl, and to remobilize nutrients held in dead standing vegetation (Ward 1968, Hackney and de la Cruz 1981, Diiro 1982, Herndon et al 1991, Laubhan 1995. Burning can destroy dormant mosquito eggs in dry wetland sediments (Wallace et al 1990, Whittle et al 1993, and mosquito densities in wetlands are lower in areas where emergent plants were burned or mowed than in unmanipulated areas Resh 1992a, de Szalay et al 1995).…”

We examined the responses of invertebrates and plants important in waterfowl diets to two management methods (prescribed burning and mowing) commonly used in seasonal wetlands. Experimental plots were constructed in summer 1992 in stands of saltgrass (Distichlis spicata); 50% of the vegetation was removed in treatment areas (10 m x 10 m) by either burning or mowing. After the plots were flooded, we sampled aquatic invertebrates monthly from we sampled plants that grew in areas that had been burned or mowed. Burning and mowing treatments had very different results. Many numerically dominant macroinvertebrates and microinvertebrates had higher densities in burned treatment areas than in unmanipulated control areas, but densities of most taxa were not different in mowed treatment areas and control areas. Copepod densities were lower in burned treatment areas and oligochaete densities were lower in mowed treatment areas than in control areas. Midge (Diptera: Chironornidae) biomass was higher in burned and mowed treatment areas than in control areas. Plant species richness and percent cover of some plant taxa were higher in burned areas than in control areas. Many of the invertebrates and plants we sampled are important in waterfowl diets, and our results indicate that these methods can enhance waterfowl food resources.

“…Pokorný et al (2010) also reported that short-term disturbances such as burning had a weak effect on Cladium mariscus populations in the Czech Republic. Studies from the southeastern USA, where Cladium jamaicense occurs, confirm that fire can reduce the stand density greatly or kill large stands of Cladium jamaicense, but it does not destroy Cladium populations (Herndon et al 1991). Experiments conducted by Ponzio et al (2004) also proved that the Cladium jamaicense population in Florida can survive fires.…”

We present the paleoecological development of a rich fen located in the dune area on the SE Baltic coast, during the last 7500 years. The Apšuciems Mire hosts rare and endangered plant communities in Europe, such as Schoenus ferrugineus and Cladium mariscus. Analysis at highresolution of plant macroremains in two peat cores was carried out to reconstruct local vegetation succession and fluctuations in moisture availability on the peatland, while a pollen record was developed to reconstruct plant succession, moisture variability and human activity at the regional scale. Based on the presence or the absence of macroremains of plants that occur in wet habitat e.g. Cladium mariscus, Schoenoplectus tabernaemontani, Alisma plantago-aquatica and Botrycoccocus we distinguished four wet periods ca. 6000, 2000, 1750-1550, 1200-150 cal yr. BP and four dry periods (ca. 7000, 4600-4200, 1800-1750, 1550-1200 cal yr. BP) in the peatland's development. A water level increase at 1200 cal yr. BP triggered the development of plant communities containing Chara sp., Schoenoplectus tabernaemontani, then Cladium mariscus. Our study shows a link between climate change at the regional scale and vegetation development in Apšuciems Mire. We showed that changes in vegetation structure during last 150 years was caused by drainage and human activity.

“…A rise in hurricane intensity, more frequent heat waves, salt-water intrusion and sea-level rise are all projected for the Everglades region (Stanton and Ackerman 2007). Disturbance and altered hydrologic regimes promote the displacement of native vegetation by introduced or formerly restricted species (Groves andBurdon 1986, Mooney andDrake 1986), and have already led to changes in vegetation community composition in the Everglades (Toth 1987, 1988, Herndon et al 1991, Urban et al 1993. Sawgrass communities in the northern Everglades have already been replaced by dense stands of cattail (Typha domingensis Pers.…”

Abstract. Shaped by the hydrology of the Kissimmee-Okeechobee-Everglades watershed, the Florida Everglades is composed of a conglomerate of wetland ecosystems that have varying capacities to sequester and store carbon. Hydrology, which is a product of the region's precipitation and temperature patterns combined with water management policy, drives community composition and productivity. As shifts in both precipitation and air temperature are expected over the next 100 years as a consequence of climate change, CO 2 dynamics in the greater Everglades are expected to change. To reduce uncertainties associated with climate change and to explore how projected changes in atmospheric CO 2 concentration and climate can alter current CO 2 exchange rates in Everglades freshwater marsh ecosystems, we simulated fluxes of carbon among the atmosphere, vegetation, and soil using the DAYCENT model. We explored the effects of low, moderate, and high scenarios for atmospheric CO 2 (550, 850, and 950 ppm), mean annual air temperature (þ1, þ2.5, and þ4.28C) and precipitation (À2, þ7, and þ14%), as predicted by the IPCC for the year 2100 for the region, on CO 2 exchange rates in short-and long-hydroperiod wetland ecosystems. Under 100 years of current climate and atmospheric CO 2 concentration, Everglades freshwater marsh ecosystems were estimated to be CO 2 -neutral. As atmospheric CO 2 concentration increased and under climate change projections, there were slight shifts in the start and length of the wet season (À1 to þ7 days) and a small enhancement in the sink capacity (by À169 to À573 g C m À2 century À1 ) occurred at both short-and longhydroperiod ecosystems compared to CO 2 dynamics under the current climate regime. Over 100 years, rising temperatures increased net CO 2 exchange rates (þ1 to 13 g C m À2 century À1) and shifts in precipitation patterns altered cumulative net carbon uptake by þ13 to À46 g C m À2 century À1. While changes in ecosystem structure, species composition, and disturbance regimes were beyond the scope of this research, results do indicate that climate change will produce small changes in CO 2 dynamics in Everglades freshwater marsh ecosystems and suggest that the hydrologic regime and oligotrophic conditions of Everglades freshwater marshes lowers the ecosystem sensitivity to climate change.
