Abstract Assessing the response of salt marshes to tidal restoration relies on comparisons ecosystem attributes between restored and reference marshes. Although this approach provides an objective basis for judging project success, inferences can be constrained if high variability natural masks differences in sampled sites. Furthermore, such assessments are usually focused a small number projects local area, limiting ability address questions regarding effectiveness within broad region. We...
SUMMARY. 1. We studied the effects of seasonal flooding on macro‐invertebrate abundance by manipulating water regime and detrital level within three contiguous experimental marshes in Manitoba, Canada, over 2 years. One area was seasonally flooded (standing present through midsummer) with emergent vegetation left undisturbed throughout study, one semipermanently ice‐free season) undisturbed, harvested at end first summer. 2. Abundances frequent macroinvertebrate taxa were compared between...
Abstract We compiled salt marsh monitoring datasets from 36 complete or imminent restoration projects in the Gulf of Maine to assess regional and practices. Data were organized by functional indicators project types (culvert replacement, excavation works, ditch plugging) then pooled generate mean values for before restoration, after at reference sites. Monitoring data checked against standards a voluntary protocol Maine. inventories showed that vegetation salinity most frequently collected...
Over half of the Zostera marina (Eelgrass) cover disappeared from Casco Bay, ME, largely between 2012 and 2013. Eelgrass decline coincided with a population explosion invasive crab Carcinus maenas (European Green Crab). Crabs have been found to damage in Atlantic Canada through foraging activity, but destruction established beds had not documented Maine. My objective was determine whether loss Bay related Crab disturbance. In September 2013, I transplanted shoots inside outside replicate...
Seagrass meadows are ecologically important habitats that declining globally at an accelerating rate due to natural and anthropogenic stressors. Their decline is a serious concern as this habitat provides many ecosystem services. Eelgrass (Zostera marina) the dominant seagrass species in western North Atlantic. It has recently been established invasive tunicate possibly threaten health of eelgrass beds. Colonization leaves by tunicates can inhibit growth may cause shoot mortality. To...
Abstract For most of the scientific disciplines associated with coastal and estuarine research, workforce representation does not match demographics communities we serve, especially for Black, Hispanic or Latino, Indigenous peoples. This essay provides an overview this inequity identifies how a society can catalyze representational, structural, interactional diversity to achieve greater inclusion. Needed changes go beyond representational require intentional commitment build capacity through...
A wetland classification system was designed for Mt. Desert Island, Maine, to help categorize the large number of wetlands (over 1,200 mapped units) as an aid understanding their hydrologic functions. The system, developed by U.S. Geological Survey (USGS), in cooperation with National Park Service, uses a modified hydrogeomorphic (HGM) approach, and assigns categories based on position landscape, soils surficial geologic setting, source water. dichotomous key determine preliminary HGM...

Communities of submerged aquatic vegetation (SAY) are important components many freshwater, brackish, and marine ecosystems. They prevent erosion by baffling the impacts waves, especially from storms. These plant communities remove nutrients other pollutants river runoff inputs to coastal areas, preventing their entry into surrounding waters. provide nursery habitat for fish, shrimp, species, as well forage wintering waterfowl endangered species such sea turtles manatees. Unfortunately, not...
