Removal of Wastewater Nitrogen and Phosphorus by an Oligohaline Marsh
… determine the role of wastewater processing by oligohaline Council Creek marsh (0.16 km2), which receives wastewater from Easton, MD. Tidal flushing, nutrient distributions, plant uptake, and sediment burial were examined as removal mechanisms. This marsh seems to be little affected by, and has …

Responses of a Louisiana oligohaline marsh plant community to nutrient loading and disturbance
Aboveground plant community dynamics in the oligohaline marsh at Big Branch Marsh National Wildlife Refuge, Louisiana, USA, were assessed in response to nutrient loading (3 N x 3 P treatments) and disturbance (both planned lethal disturbance and stochastic tropical storm/hurricane disturbance). …

Oligohaline wetland response and recovery following storm-driven saltwater intrusion in coastal Louisiana
… conditions on the structure and growth of an oligohaline wetland plant community, and on wetland soil biogeochemistry and conditions during and after saltwater intrusion. In the greenhouse, a six-week saltwater intrusion reduced canopy cover and species richness. Once intrusion stress was …

RESPONSE OF A SPARTINA PATENS-DOMINATED OLIGOHALINE MARSH TO NITROGEN ENRICHMENT IN COASTAL NORTH CAROLINA, USA.
… fertilize plots in a Spartina patens-dominated oligohaline marsh with varying concentrations of urea applied throughout one growing season and assess the response in aboveground and belowground plant biomass and decomposition. Aboveground plant clippings and soil cores were collected to assess …

Distribuição dos peixes nos estuários do nordeste brasileiro de acordo com a salinidade da água
… into 5 ichthyofaunistic components: fresh water, oligohaline, marine stenohaline, marine euryhaline and complet euryhaline. The freshwater component, comprises a few salt-tolerant species derived from the rivers and found in salinities below 15° /oo. The oligohaline component, those species with …

Artificial Reef Performance in Lake Pontchartrain, Louisiana
… of artificial reefs were constructed in a large oligohaline estuary, Lake Pontchartrain, Louisiana to improve recreational fisheries. The reefs are the first in Louisiana to be built of reef balls, concrete domes deployed primarily in marine environments. Although they attract fish and …

Biology and Impacts of Leech Infestation in Largemouth Bass (Micropterus Salmoides) in Back Bay, Virginia
<p>Back Bay is an oligohaline coastal bay in Southeast Virginia, USA. The Oregon Inlet along the Outer Banks of North Carolina is the only significant salinity source to the Bay via the Pamlico and Currituck Sounds of North Carolina. Today Back Bay is considered a brackish ecosystem with salinity …

Effect of Fragmentation and Habitat Type on Coastal Nekton in Mississippi
… data for non-harvested marsh nekton collected in oligohaline marshes (salinity 0.5-5ppt) of coastal Mississippi. To assess how nekton assemblages varied by habitat, fragmentation level and position in patch (core vs. edge), four sites along coastal Mississippi were sampled in the summers of 2014 …

Multifunctional experimental assessment in a newly established Mediterranean restored marsh : marsh elevation, carbon accumulation and pollutant concentration reduction
… concentration reduction in Mediterranean oligohaline restored marshes. We conducted a 3-year experimental field study in a newly established restored marsh using two different freshwater input types, riverine irrigation water (IW) and rice field drainage water (DW) and three water levels …

Synoptic scale climatic forcing of multispecies fish recruitment patterns in Chesapeake Bay
… these two species groups utilize freshwater and oligohaline reaches of the Bay and its tributaries as springtime nursery areas, this Chesapeake Bay Anadromous-Shelf Spawner (CBASS) recruitment pattern was compared to spring climatic variability in the Mid Atlantic region. Using principal …

Taxonomia e aspectos biogeográficos da flora planctônica de um sistema costeiro salobro - Lagoa Carapebus, município de Carapebus, RJ
… Jurubatiba werc presented. This is a shallow and oligohaline lagoon with dark and slightly alcaline waters. Taxonomical study was based on 145 samples collected by a plankton net and by passing a ílask along water subsurfce at fur stations in February, March, July and October 1996 (Period I), …

Enhancing Vallisneria americana restoration using knowledge of genotypic and phenotypic diversity
… aquatic plant that once dominated freshwater to oligohaline environments in eastern North America. After dramatic declines it is the target of many restoration initiatives. To increase knowledge of the capacity of remaining populations to either adapt through natural selection or acclimate to …

Modeling the spatial and temporal dynamics of coastal marsh birds
… Study sites were in the fresh and intermediate (oligohaline) marshes of the Chenier Plain coastal region of southwest Louisiana and southeast Texas. I captured king rails for a two year radio telemetry study, and conducted point count surveys of marsh birds from March to mid-June of 2009-2011 …

Spray Aerosols From Saltwater to Freshwater Breaking Waves
… abundance, which exhibited a peak at lower oligohaline conditions (0.5-1 g/kg). However, the aerosolization of microplastics by SSAs was one order of magnitude higher than that by LSAs. Overall, this dissertation work showed that LSA emissions are intrinsically different from SSA emissions, …

Microzooplankton Dynamics in Lower Chesapeake Bay and Its Major Tributaries
… of microzooplankton density and biomass, oligohaline statons (river-estuary transitional sites) generally had the highest microzooplankton density and biomass. Pearson's correlation analysis identified several consistent relationships between microzooplankton density and the environmental …
