Salt marsh resilience compromised by crabs along tidal creek edges
coastal marshes ecosystem crab
2021/8/10
Coastal marshes are vulnerable to erosion caused by rising seas, pounding waves, and tidal flows. In California's Elkhorn Slough, these vulnerabilities are made worse by superabundant crabs found at t...
On the Movement of Beluga Whales in Cook Inlet,Alaska:Simulations of Tidal and Environmental Impacts Using a Hydrodynamic Inundation Model
Beluga Whales Cook Inlet Alaska Tidal and Environmental Hydrodynamic Inundation Model
2015/7/22
The population of beluga whales in Cook Inlet, Alaska, is in decline, and since 2000 these whales have been under consideration for designation as "endangered" under the Endangered Species Act (and we...
Movement Patterns and Catch-and-Release Impacts of Striped Bass in a Tidal Coastal Embayment in Massachusetts
accelerometers catch-and-release stress
2014/11/5
An investigation into the spatial ecology and effects of catch-and-release angling on the physiology and behavior of striped bass was conducted. Fine-scale behavior was assessed by tagging fish with a...

Pore-water exchange driven by tidal pumping causes alkalinity export in two intertidal inlets
intertidal inlets idal pumping
2014/10/16
Carbon (C) and alkalinity export from two adjacent intertidal inlets with different terrestrial inputs was
investigated. One inlet receives a small creek from an agriculturally dominated catchment, l...
Effects of turbulence-mediated larval behavior on larval supply and settlement in tidal currents
turbulence-mediated larval larval supply settlement in tidal currents
2014/4/22
Intertidal gastropod larvae retract their vela and sink in strong turbulence, and this behavior potentially increases settlement in turbulent coastal habitats. We incorporated turbulence-induced sinki...
Secondary production of a dominant oligochaete (Monopylephorus rubroniveus) in the tidal creeks of South Carolina and its relation to ecosystem characteristics
Secondary production a dominant oligochaete tidal creeks of South Carolina relation ecosystem characteristics
2014/5/9
Measurements of the annual production of the oligochaete Monopylephorus rubroniveus, microphytobenthos, pore-water ammonia, sediment composition, and water quality were made from January through Decem...
Biomarker and carbon isotopic constraints on bacterial and algal community structure and functioning in a turbid, tidal estuary
Biomarker carbon isotopic constraints bacterial and algal community structure functioning tidal estuary
2014/5/8
We studied planktonic community structure and isotopic composition using compound-specific 13C analysis of phospholipid-derived fatty acids (PLFA) along the Scheldt estuary during a spring bloom. A co...
Tidal dynamics of dissolved and particulate matter and bacteria in a tidal flat ecosystem in spring and fall
Tidal dynamics of dissolved particulate matter bacteria in a tidal flat ecosystem spring and fall
2014/5/19
Tidal flat ecosystems are highly dynamic environments with tremendous short-term and long-term changes in physical, chemical, and biological properties. We measured salinity, temperature, oxygen, dry ...
Benthic metabolism and sulfur cycling along an inundation gradient in a tidal Spartina anglica salt marsh
Benthic metabolism sulfur cycling inundation gradient tidal Spartina anglica saltmarsh
2014/5/22
Central aspects of carbon and sulfur biogeochemistry were studied along a transect extending from an unvegetated mudflat into a Spartina anglica salt marsh. Conditions along the transect differed with...
Annual primary production: Patterns and mechanisms of change in a nutrient-rich tidal ecosystem
Annual primary production Patterns and mechanisms of change nutrient-rich tidal ecosystem
2014/5/27
Although nutrient supply often underlies long-term changes in aquatic primary production, other regulatory processes can be important. The Sacramento-San Joaquin River Delta, a complex of tidal waterw...
Sequential resuspension of protists by accelerating tidal flow: Implications for community structure in the benthic boundary layer
Sequential resuspension protists accelerating tidal flow community structure benthic boundary layer
2014/5/27
We measured resuspension thresholds of protists and bacteria at a subtidal coastal site with in situ flumes and by sampling the benthic boundary layer during tidal accelerations. Heterotrophic nanofla...
Nutritional quality of food resources for zooplankton (Daphnia) in a tidal freshwater system (Sacramento–San Joaquin River Delta)
Nutritional quality food resources zooplankton a tidal freshwater system
2014/5/26
We examined the relative nutritional values of natural phytoplankton and particulate detritus for zooplankton growth in a detritus-rich environment. Seston was collected seasonally from four different...
