Seagrass restoration has often not been successful due to poor site planning, physical disturbance, transplant timing incompatibility, and physical and biological disturbances. As such, these factors are important for successfully restoring seagrasses, and global success has greatly increased. We conducted restorations in the mid-Atlantic region of...
Article
Full-text available
Cyanobacterial harmful algal blooms (CHAB), caused by eutrophication, are known to threaten both wildlife and human health. Due to urbanization and land use changes, an increase of CHAB’s at a more frequent rate within Barnegat Bay has been observed. In order to detect possible CHAB causing cyanobacteria, water samples were collected from 12 differ...
Article
Full-text available
Colonization of eelgrass (Zostera marina L.) by tunicates can lead to reduced plant growth and survival. Several of the tunicate species that are found on eelgrass in the northwest Atlantic are highly aggressive colonizers, and range expansions are predicted in association with climate-change induced increases in seawater temperature. In 2017, we s...

Taxonomic shifts can alter predator feeding preference and modify ecosystem dynamics through top-down control. In Barnegat Bay-Little Egg Harbor Estuary (New Jersey, USA), sea nettle Chrysaora quinquecirrha abundances have increased in the northern portions of the estuary. We evaluated the geographical variation in top-down influence of C. quinquec...
Conference Paper
Full-text available
Urbanization of estuaries has dramatically altered shorelines through habitat removal and destruction, as well as construction of permanent structures like docks, bulkheads, and piers. Concomitantly, water quality degradation has occurred from various pollutants and excess nutrients derived from anthropogenic sources. Excessive nutrients result in...
Article
Hurricanes severely damaged a mangrove forest in a UNESCO biosphere reserve in the U.S. Virgin Islands. The system has yet to recover and when alternative habitats have been destroyed, it is shown that juvenile fishes will hyperutilize seagrass beds at densities significantly greater than in areas that maintain functioning mangroves. Despite over a...
Technical Report
Full-text available
During the 2012 field season, we collected samples from 16 sites in Barnegat Bay to assess the distribution of gelatinous zooplankton, with emphasis on all life history stages of sea nettles (Chrysaora quinquecirrha) and potential impacts on the pelagic zooplankton communities. During the research, 384 plankton tow samples were collected, 1152 filt...
