Salt Marsh Ecology in an Era of Sea Level Rise

Under the right circumstances, salt marshes have the ability to increase their elevation, and therefore may be able to “keep up” with sea level rise. We are working to understand ...

Erratum to: Synthesis in estuarine and coastal ecological research

A caveat in the concluding section of our paper states that it would be impossible to provide a comprehensive sample of synthesis case studies that reflects all the major research areas in estuarine and coastal science. In retrospect, however, we ...

Estimates of the Direct Effect of Seawater pH on the Survival Rate of Species Groups in the California Current Ecosystem

Ocean acidification (OA) has the potential to restructure ecosystems due to variation in species sensitivity to the projected changes in ocean carbon chemistry. Ecological models can be forced with scenarios of OA to help scientists, managers, and other stakeholders understand ...

Evaluating confidence in the impact of regulatory nutrient reduction on Chesapeake Bay water quality

Excess nutrients derived from anthropogenic activity have resulted in the degradation of coastal water quality and an increase in low-oxygen and hypoxic events worldwide. In an effort to curb these impacts and restore water quality in the Chesapeake Bay, a ...

Evaluating estuarine habitats using secondary production as a proxy for food web support

The management, restoration, and conservation of estuarine habitats would benefit from knowledge of habitat-specific functions that reflect important ecosystem services. Secondary production may provide a comprehensive metric of food web support because it synthesizes ­contributions of local primary production, food ...

Evaluation of Lower Green Bay benthic fauna with emphasis on re-ecesis of Hexagenia mayfly nymphs

The last historic Hexagenia specimen in lower Green Bay was officially recorded in 1955. Field surveys and Hexagenia viability studies were completed to determine if lower Green Bay could support Hexagenia re-ecesis and where in the bay egg stocking could ...

Evidence of climate-driven ecosystem reorganization in the Gulf of Mexico

The Gulf of Mexico is one of the most ecologically and economically valuable marine ecosystems in the world and is affected by a variety of natural and anthropogenic phenomena including climate, hurricanes, coastal development, agricultural runoff, oil spills, and fishing ...

Evidence of persistent, recurring summertime hypoxia in Green Bay

Six years (2009–2015) of temperature and dissolved oxygen profile data show hypoxic conditions are common in the bottom waters of southern Green Bay, Lake Michigan during the summer. Depleted oxygen concentrations (<5 mg L−1) affect nearly 70% of the 38 ...

Exceptionally high organic nitrogen concentrations in a semi-arid South Texas estuary susceptible to brown tide blooms

Studies of estuarine eutrophication have tended to focus on systems with continually flowing rivers, while little is known about estuaries from semi-arid/arid regions. Here we report results from an assessment of water quality conditions in Baffin Bay, Texas, a shallow ...

Extending Vulnerability Assessment to Include Life Stages Considerations

Species are experiencing a suite of novel stressors from anthropogenic activities that have impacts at multiple scales. Vulnerability assessment is one tool to evaluate the likely impacts that these stressors pose to species so that high-vulnerability cases can be identified ...
