Eutrophication-Driven Deoxygenation in the Coastal Ocean
Eutrophication-Driven Deoxygenation Coastal Ocean
2015/7/17
Human activities, especially increased nutrient loads that set in motion a cascading chain of events related to eutrophication, accelerate development of hypoxia (lower oxygen concentration) in many a...
Effects of land use, urbanization, and climate variability on coastal eutrophication in the Baltic Sea
land use urbanization climate variability coastal eutrophication in the Baltic Sea
2014/4/17
Sedimentary records of organic matter inputs (stable nitrogen isotopes [d15N], nitrogen [N], and carbon [C] content), phytoplankton abundance (pigments, stable carbon isotopes [d13C]), and community c...
Investigating the use of macrophyte stable C and N isotopic ratios as indicators of wetland eutrophication: Patterns in the P-affected Everglades
macrophyte stable C N isotopic ratios wetland eutrophication Patterns in the P-affected Everglades
2014/5/5
We investigated the use of stable C and N isotopic ratios as indicators of shifts in nutrient limitation of aquatic macrophytes in native Typha (Typha domingensis Pers.) and Cladium (Cladium jamaicens...
Long-term trends in eutrophication and nutrients in the coastal zone
eutrophication nutrients coastal zone
2014/4/30
We used high-resolution paleoecological records of environmental change to study the rate and magnitude of
eutrophication over the last century in two contrasting coastal ecosystems. A multiproxy app...
Microbial production, utilization, and enzymatic degradation of organic matter in the upper trophogenic layer in the pelagial zone of lakes along a eutrophication gradient
Microbial production utilization enzymatic degradation
2014/4/30
The major aim of this study was to evaluate the relationships between the rates of microbial activities (phytoplankton primary production, bacterial secondary production, bacterial utilization of orga...
Periphyton responses to eutrophication in the Florida Everglades: Cross-system patterns of structural and compositional change
Periphyton Florida Everglades Cross-system patterns
2014/4/30
We examined periphyton along transects in five Everglades marshes and related compositional and functional
aspects to phosphorus (P) gradients caused by enriched inflows. Results were com...
Many natural streams are net heterotrophic, so I propose that trophic state be divided into autotrophic and
heterotrophic state. This division allows consideration of the influence of external ...
Sediment geochemical records of eutrophication in the mesohaline Chesapeake Bay
Sediment geochemical records eutrophication mesohaline Chesapeake Bay
2014/5/27
An organic geochemical analysis of sediments in three cores from the mesohaline Chesapeake Bay was carried out to reconstruct the progression of eutrophication and anoxia/hypoxia over the past five ce...
