An estuarine benthic index of biotic integrity (B-IBI) for Chesapeake Bay
A multimetric benthic index of biotic integrity (B-IBI) was developed using data from five Chesapeake Bay sampling programs conducted between 1972 and 1991. Attributes of the index were selected byExpand
Consequences of Climate Change on the Ecogeomorphology of Coastal Wetlands
Climate impacts on coastal and estuarine systems take many forms and are dependent on the local conditions, including those set by humans. We use a biocomplexity framework to provide a perspective ofExpand
Assessing estuarine benthic quality conditions in Chesapeake Bay: A comparison of three indices
Abstract Legislation in US and Europe has been adopted to determine the ecological integrity of estuarine and coastal waters, including, as one of the most relevant elements, the benthicExpand
Sea-bed Mixing and Particle Residence Times in Biologically and Physically Dominated Estuarine Systems: a Comparison of Lower Chesapeake Bay and the York River Subestuary
Biologically dominated lower Chesapeake Bay and the physically dominated York River subestuary are contrasted in terms of the dynamics of sediment mixing, strata formation and sea-bed particleExpand
Spatial and temporal variation in cohesive sediment erodibility in the York River estuary, eastern USA: A biologically influenced equilibrium modified by seasonal deposition
Abstract Sediment erodibility was measured at three sites in the York River, a sub-estuary of the Chesapeake Bay, monthly to bimonthly from April 2006 through October 2007. Erodibility at the threeExpand
Hypoxia-induced structural changes in the diet of bottom-feeding fish and Crustacea
Interactive effects of three alternating normoxia-hypoxia cycles on benthic prey exploitation by mobile fish (spot, Leiostomus xanthurus; and hogchoker, Trinectes maculatus) and a burrowingExpand
Effects of periodic hypoxia on mortality, feeding and predation in an estuarine epifaunal community.
The York River Estuary, a tributary of the Chesapeake Bay, USA, experiences periodic low oxygen stress (hypoxia), yet epifaunal species form dense communities there. We studied hypoxia tolerance ofExpand
Biological mediation of bottom boundary layer processes and sediment suspension in the lower Chesapeake Bay
Abstract In relatively low-energy estuarine environments where bottom skin friction shear stresses do not appreciably exceed the critical shear stress required for sediment transport, benthic biologyExpand
The concept of a equilibrium surface applied to particle sources and contaminant distributions in estuarine sediments
Studies have shown that many chemically-reactive contaminants become associated with fine particles in coastal waters and that the rate, patterns, and extent of contaminant accumulation withinExpand
Continuous monitoring of dissolved oxygen in an estuary experiencing periodic hypoxia and the effect of hypoxia on macrobenthos and fish
ABSTRACT Hypoxic bottom water (defined as * ) is now a common occurrence in many estuarine and coastal systems. If prolonged and widespread, hypoxia could present a serious threat to the ecologicalExpand
