Phytoplankton photopigments as indicators of estuarine and coastal eutrophication
(, 2003 Oct)
Human development of coastal watersheds has greatly increased nutrient loading and accelerated estuarine and coastal eutrophication. These waters are also affected by climatic perturbations (e.g., droughts, hurricanes, ...
Phytoplankton community growth-rate response to nutrient pulses in a shallow turbid estuary, Galveston Bay, Texas
(, 2004 Mar)
Phytoplankton growth is a physiological process often limited by temperature, nutrients or light, while biomass accumulation is a function of growth rates, grazing and deposition. Although primary productivity measurements ...
Copepod prey selection in a shallow turbid estuary, Galveston Bay, Texas - Watermelons, oranges, or grapes?

Characterizing man-made and natural modifications of microbial diversity and activity in coastal ecosystems
The impacts of growing coastal pollution and habitat alteration accompanying human encroachment are of great concern at the microbial level, where much of the ocean's primary production and biogeochemical cycling takes ...
Quantification of the relative abundance of the toxic dinoflagellate, Karenia brevis (Dinophyta), using unique photopigments
(, 2003 Apr)
Diagnostic photopigment analysis is a useful tool for determining the presence and relative abundance of algal groups in natural phytoplankton assemblages. This approach is especially useful when a genus has a unique ...
Spatial study of benthic microalgae in an intertidal sandflat at East Beach, Galveston Bay, Texas

Nutrient pulsing as a regulator of phytoplankton abundance and community composition in Galveston Bay, Texas
(, 2002 Sep 1)
Galveston Bay, Texas, is a large shallow estuary with a watershed that includes 60% of the major industrial facilities of Texas. However, the system exhibits low to moderate (2-20 [mu]g l-1) microalgal biomass with sporadic ...
Estuarine phytoplankton group-specific responses to sublethal concentrations of the agricultural herbicide, atrazine
(, 2002 Oct)
Atrazine is a common agricultural herbicide that is readily transported into estuaries through surface water runoff. In this study, we determined the short-term (24-48 h) sublethal effects of atrazine on estuarine phytoplankton ...
Microbial indicators of aquatic ecosystem change: current applications to eutrophication studies
(, 2003 Dec 5)
Human encroachment on aquatic ecosystems is increasing at an unprecedented rate. The impacts of human pollution and habitat alteration are most evident and of greatest concern at the microbial level, where a bulk of ...
