“…These patterns suggest a midsalinity source of NN to the water column, and much of this pattern was driven by data from the three mangrove sites. This is consistent with mangrove flux data that showed uptake of NH and release of NN, particularly during the higher salin-ϩ 4 ity dry season (Davis et al 2001a,b) when we hypothesize relatively long water residence times in this area (Fig. 8B).…”

“…Tidal advection from the Gulf of Mexico is quickly attenuated by the western mud banks, reducing astronomical tides at TS/ Ph-10. Wind forcing dominates tidal fluctuations at TS/Ph-9 and at our oligohaline estuarine ecotone sites (TS/Ph-6, -7, and -8; Davis et al 2004). Although precipitation is the largest source of freshwater to Florida Bay (Nuttle et al 2000), freshwater inputs from Taylor Slough and the C-111 basin/ENP panhandle do affect salinity in the eastern bay (Boyer and Jones 1999;Nuttle et al 2000).…”

“…Our TN data show an opposite pattern, though, with lower [TN] at the freshwater SRS sites when the S-12C gates are open and water is actively flowing down-slough. There is considerable evidence that freshwater Everglades wetlands are sources of dissolved organic N (DON; Davis et al 2003;Lu et al 2003;Parker 2000). This internal N source appears to be associated with slower processes that are most evident during the dry season, when the S-12 structures are closed and water residence times are longer.…”

We present 8 yr of long-term water quality, climatological, and water management data for 17 locations in Everglades National Park, Florida. Total phosphorus (P) concentration data from freshwater sites (typically Ͻ0.25 mol L Ϫ1 , or 8 g L Ϫ1 ) indicate the oligotrophic, P-limited nature of this large freshwater-estuarine landscape. Total P concentrations at estuarine sites near the Gulf of Mexico (average ഠ0.5 mol L Ϫ1 ) demonstrate the marine source for this limiting nutrient. This ''upside down'' phenomenon, with the limiting nutrient supplied by the ocean and not the land, is a defining characteristic of the Everglade landscape. We present a conceptual model of how the seasonality of precipitation and the management of canal water inputs control the marine P supply, and we hypothesize that seasonal variability in water residence time controls water quality through internal biogeochemical processing. Low freshwater inflows during the dry season increase estuarine residence times, enabling local processes to control nutrient availability and water quality. El Niño-Southern Oscillation (ENSO) events tend to mute the seasonality of rainfall without altering total annual precipitation inputs. The Niño3 ENSO index (which indicates an ENSO event when positive and a La Niña event when negative) was positively correlated with both annual rainfall and the ratio of dry season to wet season precipitation. This ENSO-driven disruption in seasonal rainfall patterns affected salinity patterns and tended to reduce marine inputs of P to Everglades estuaries. ENSO events also decreased dry season residence times, reducing the importance of estuarine nutrient processing. The combination of variable water management activities and interannual differences in precipitation patterns has a strong influence on nutrient and salinity patterns in Everglades estuaries.Nutrient enrichment and cultural eutrophication affect virtually all aquatic systems to some degree (Carpenter et al.

“…These and other studies have documented the impacts of such storms on subsequent structure and function of mangrove forests, including defoliation and losses of branches or entire trees (Davis 1995;Baldwin et al 2001;Davis et al 2004;Profitt et al 2006;Ward et al 2006;Smith et al 2009;Whelan et al 2009;Castaneda-Moya et al 2010;Harris et al 2010). Recovery of mangroves after hurricane disturbance is a function of a complex interaction of factors, including seedling recruitment and survival, resprouting capability, and colonization by herbaceous vegetation (Baldwin et al 2001).…”

“…Typha domingensis tolera un nivel mayor de salinidad (Glenn et al, 1995), más que otras especies de humedales herbáceos emergentes. También se debe tener en cuen-ta al banco de semillas del suelo y el banco de rizomas y estolones que favorece la regeneración de algunas especies sobre otras cuando la vegetación existente es removida (Ló-pez Rosas et al 2006;Osland, 2009) o por algún disturbio natural (Davis et al, 2004). La capacidad de crecimiento vegetativo de muchas de estas especies es un factor que probablemente favorece su dominancia.…”

Los humedales tienen gran importancia por los recursos que se obtienen de ellos (pesca, madera, miel, cacería, plantas medicinales, entre otros) y los servicios ambientales que proporcionan, ya que son la base de las actividades pesqueras, ayudan en el control de inundaciones, en la fi ltración y limpieza del agua y en la protección de las zonas costeras, en el aporte de nutrientes a los cuerpos de agua, proporcionan refugio a los juveniles de especies acuáticas entre los más importantes (Costanza et al., 1998;Semlitsch y Bodie, 1998 Resumen: Se describe la composición fl orística, diversidad y ecología de humedales herbáceos de la planicie costera de Veracruz, entre Tecolutla y la cuenca baja del río Papaloapan, teniendo éstos últimos mayor diversidad, principalmente laguna Conejo. Once localidades fueron muestreadas, encontrándose 95 especies (41 familias y 74 géneros). La clasifi cación jerárquica Beta Flexible conformó nueve grupos; para cada uno se grafi có el régimen de inundación anual. La ordenación por componentes principales explicó el 47.81% de la variación mostrando un gradiente de riqueza de especies de los sitios de la zona norte y centro hacia los del Papaloapan, así como un gradiente de suelos Gleysol e Histosol (predominando histosoles en el Papaloapan). Existe gran variabilidad en la composición fl orística y dominancia de los humedales herbáceos emergentes y se considera que forman un complejo de riqueza de especies y combinaciones de monocotiledóneas y dicotiledóneas por lo que se sugiere usar el término popal-tular para denominarlos. Palabras clave: Cyperus giganteus, diversidad, hidroperíodo, Sagittaria lancifolia, popal Abstract: This work describes the fl oristic composition, ecology and diversity of marshes along the central coastal plain of Veracruz, from Tecolutla to the lowlands of the Papaloapan River, where more diverse sites were found (highest value in Conejo Lagoon). Eleven localities were sampled and 95 species were recorded (41 families and 74 genus). The classifi cation (hierarchic Beta Flexible) grouped species in nine types and annual hydroperiods were represented graphically for each type. PCA explained 47.81% of the variation and samples showed a gradient in species richness from northern and central sites towards the Papaloapan as well as a soil gradient from Gleysols to Histosols (predominating in Papaloapan). The great variability in species composition and dominance suggests that they form a landscape complex with different combinations of monocotyledons and dicotyledons which should be named popal-tular.
