  • Mummichog Fundulus heteroclitus responses to long-term, whole-ecosystem nutrient enrichment 

    Lockfield, Konner C.; Fleeger, John W.; Deegan, Linda A. (2013-05)
    The effects of eutrophication on coastal plants and sessile animals are becoming well known, but responses of mobile species are less well studied. Here, we link variation in abundance, biomass, body size, growth rate, and ...
  • The response of nematodes to deep-sea CO2 sequestration : a quantile regression approach 

    Fleeger, John W.; Johnson, David S.; Carman, K. R.; Weisenhorn, P. B.; Gabriele, A.; Thistle, D.; Barry, James P. (2010-01)
    One proposed approach to ameliorate the effects of global warming is sequestration of the greenhouse gas CO2 in the deep sea. To evaluate the environmental impact of this approach, we exposed the sediment-dwelling fauna ...
  • Response of the benthic food web to short- and long-term nutrient 1 enrichment in saltmarsh mudflats 

    Pascal, Pierre-Yves; Fleeger, John W.; Boschker, Henricus T. S.; Mitwally, Hanan M.; Johnson, David S. (2013-01)
    We examined the responses of biota at or near the base of the benthic food web to nutrient enrichment in salt marsh mudflats in Plum Island estuary (Massachusetts, USA). To simulate eutrophication, nitrate and phosphate ...
  • Susceptibility of salt marshes to nutrient enrichment and predator removal 

    Deegan, Linda A.; Bowen, Jennifer L.; Drake, Deanne C.; Fleeger, John W.; Friedrichs, Carl T.; Galvan, Kari A.; Hobbie, John E.; Hopkinson, Charles S.; Johnson, J. Michael; Johnson, David S.; LeMay, Lynsey E.; Miller, Erin; Peterson, Bruce J.; Picard, Christian; Sheldon, Sallie; Sutherland, Michael; Vallino, Joseph J.; Warren, R. Scott (2006-03-15)
    The sustainability of coastal ecosystems in the face of widespread environmental change is an issue of pressing concern throughout the world (Emeis et al. 2001). Coastal ecosystems form a dynamic interface between terrestrial ...
  • Top-down and bottom-up control of infauna varies across the saltmarsh landscape 

    Fleeger, John W.; Johnson, David S.; Galvan, Kari A.; Deegan, Linda A. (2007-12)
    Responses of infaunal saltmarsh benthic invertebrates to whole-ecosystem fertilization and predator removal were quantified in Plum Island Estuary, Massachusetts, USA. Throughout a growing season, we enriched an experimental ...
