Sediment microalgae play an important role in nutrient cycling and are important primary producers in the food web in Pacific Northwest estuaries. This study examines the effects of nitrogen addition to benthic microalgae in tidal wetlands of Yaquina Bay estuary on the Oregon coast, USA. Liquid nitrogen fertilizers (0, 0.2, 0.5, and 1.0 gN/m2/wk during the first year of the study, and increased to 0, 15.6, 62.5, and 156 gN/m2/wk during the second year of the study) were applied weekly to four…

Response of Primary Producer Communities to Short-Term Nutrient Additions in a Pacific Northwest Estuarine Tidal Wetland
While the detrimental effects of excess nutrients have been documented for tidal wetlands in many locations, the response of the primary producer community to nutrients in Pacific Northwest wetlands
Tidal Channel Diatom Assemblages Reflect within Wetland Environmental Conditions and Land Use at Multiple Scales
We characterized regional patterns of the tidal channel benthic diatom community and examined the relative importance of local wetland and surrounding landscape level factors measured at multiple
Nitrogen cycle in the hyporheic zone of natural wetlands
Nitrogen (N) is one of the most important components and ecological factors for natural wetland ecosystems. It is mainly derived from runoff input, atmospheric deposition, and biological N fixation.
Assessing the efficiency of low-cost cleaning methods for diatoms from intertidal sediment samples.
H2O2 and HNO3 showed better results for diatom species richness and diversity, followed by NaClO, which was more robust since it obtained good results regardless of temperature and pre-treatments and should be preferred.


Effects of Nutrient Enrichment on Microalgal Community Composition in a Coastal Shallow-water Sediment System: An Experimental Study
The effect of increased concentrations of inorganic nitrogen and phosphorus on microalgal community composition and the question has been raised whether an increasing eutrophication in the marine environment, implying changed ratios of nutrient supply, is currently changing the basis for the pelagic food web.
Distribution of Diatoms and Development of Diatom-Based Models for Inferring Salinity and Nutrient Concentrations in Florida Bay and Adjacent Coastal Wetlands of South Florida (USA)
The composition and distribution of diatom algae inhabiting estuaries and coasts of the subtropical Americas are poorly documented, especially relative to the central role diatoms play in coastal
Algal responses to experimental nutrient addition in the littoral community of a subtropical lake
The hypothesis that phytoplankton become dominant at high nutrient loading rates was not supported, but there were dramatic changes in community structure and function in response to nutrient additions.
Nutrient Fluxes in the Microalgal-dominated Intertidal Regions of the Lower Yaquina Estuary, Oregon (USA)
The effects of benthic microalgae on sediment nutrient fluxes were investigated at three sites across the intertidal zone of lower Yaquina Bay. Study sites were selected where microalage were present
Distribution of estuarine benthic diatom species along salinity and nutrient gradients
Though there were no significant patterns in microalgal biomass in relation to nutrient enrichment, there were significant differences in the population densities of different epipelic species along a multivariate nutrient gradient.
Upward cascading effects of nutrients: shifts in a benthic microalgal community and a negative herbivore response
This study demonstrated strongly negative upward cascading effects of nutrient enrichment through the food chain, closely linked to sediment type and microalgal community composition.
Salicornia virginica in a southern California salt marsh: Seasonal patterns and a nutrient-enrichment experiment
Data suggest that increases in nutrients (especially N, but also P) can lead to large changes in S. virginica characteristics even in estuaries with high sediment nutrient levels.
Algal mat productivity: Comparisons in a salt marsh
This paper documents the role of salt marsh algal mats in the productivity of a southern California tidal wetland. The productivity of the mats, which are composed of filamentous bluegreen and green
Biodiversity-ecosystem function relationship in microphytobenthic diatoms of the Westerschelde estuary
The results indicate that biomass appears to be inversely related to the diversity of the biofilms, and relationships between diversity and Pn appeared to be site specific, with either a significant positive or a unimodal relationship between both parameters.
Effects of nutrients and water levels on emergent macrophyte biomass in a prairie marsh
Nitrogen and phosphorus fertilizers were added over two growing seasons to marshes dominated by whitetop grass or cattail in a prairie lacustrine marsh to assess nutrient limitation and the interaction of nutrient limitation with water depth.
