Controlling Eutrophication along the Freshwater-Marine Continuum: Dual Nutrient (N and P) Reductions are Essential

Hans W. Paerl, Auteur

Dans Estuaries and Coasts (32(4) JUL 2009)

Expanding human activities along the freshwater to marine continuum of coastal watersheds increasingly impact nutrient inputs, nutrient limitation of primary production, and efforts to reduce nutrient over-enrichment and eutrophication. Historic[...]

Hydrologic Variability and Its Control of Phytoplankton Community Structure and Function in Two Shallow, Coastal, Lagoonal Ecosystems: The Neuse and New River Estuaries, North Carolina, USA

Hans W. Paerl, Auteur ; Nathan S. Hall, Auteur ; Benjamin L. Peierls, Auteur ; Karen L. Rossignol, Auteur ; Alan R. Joyner, Auteur

Dans Estuaries and Coasts (37(1) JAN 2014)

Hydrologic conditions, especially changes in freshwater input, play an important, and at times dominant, role in determining the structure and function of phytoplankton communities and resultant water quality of estuaries. This is particularly t[...]

Non-monotonic Responses of Phytoplankton Biomass Accumulation to Hydrologic Variability: A Comparison of Two Coastal Plain North Carolina Estuaries

Benjamin L. Peierls, Auteur ; Nathan S. Hall, Auteur ; Hans W. Paerl, Auteur

Dans Estuaries and Coasts (35(6) NOV 2012)

Freshwater inputs often play a more direct role in estuarine phytoplankton biomass (chlorophyll a) accumulation than nitrogen (N) inputs, since discharge simultaneously controls both phytoplankton residence time and N loading. Understanding this[...]

Phytoplankton Community Indicators of Short- and Long-term Ecological Change in the Anthropogenically and Climatically Impacted Neuse River Estuary, North Carolina, USA

Hans W. Paerl, Auteur ; Karen L. Rossignol, Auteur ; S. Nathan Hall, Auteur ; Benjamin L. Peierls, Auteur ; Michael S. Wetz, Auteur

Dans Estuaries and Coasts (33(2) MAR 2010)

Estuarine and coastal systems represent a challenge when it comes to determining the causes of ecological change because human and natural perturbations often interact. Phytoplankton biomass (chlorophyll a) and group-specific photopigment indica[...]

Transparent Exopolymer Particles (TEP) in a River-Dominated Estuary: Spatial-Temporal Distributions and an Assessment of Controls upon TEP Formation

Michael S. Wetz, Auteur ; Meredith C. Robbins, Auteur ; Hans W. Paerl, Auteur

Dans Estuaries and Coasts (32(3) MAY 2009)

Transparent exopolymer particle (TEP) distributions were examined in North Carolina's Neuse River Estuary (NRE) over a 1-year period, and experiments were conducted to examine controls upon TEP formation. TEP-carbon averaged 16% of the total org[...]
