  • Fatty acid profiles in the gonads of the sea urchin Strongylocentrotus droebachiensis on natural algal diets 

    Kelly, Jennifer R., Robert E. Scheibling, Sara J. Iverson, and Patrick Gagnon. 2008. "Fatty acid profiles in the gonads of the sea urchin Strongylocentrotus droebachiensis on natural algal diets." Marine Ecology Progress Series 373: 1-9. doi:10.3354/meps07746
    We examined fatty acid (FA) compositions of gonads of the green sea urchin Strongylocentrotus droebachiensis collected from a grazing aggregation (front) at the edge of a kelp bed and from barrens dominated by coralline ...

  • Fatty acids as dietary tracers in benthic food webs 

    Kelly, Jennifer R., and Robert E. Scheibling. 2011. "Fatty acids as dietary tracers in benthic food webs." Marine Ecology Progress Series 446: 1-22. doi:10.3354/meps09559
    Fatty acid (FA) analysis is a well-established tool for studying trophic interactions in marine habitats. However, its application to benthic food webs poses 2 particular challenges. First, unlike pelagic zooplankton, ...

  • Fatty acids tracers for native and invasive macroalgae in an experimental food web 

    Kelly, Jennifer R., Robert E. Scheibling, and Sara J. Iverson. 2009. "Fatty acids tracers for native and invasive macroalgae in an experimental food web." Marine Ecology Progress Series 391: 53-63. doi:10.3354/meps08234
    We assessed the potential of fatty acid (FA) markers for tracing primary production from an invasive green alga (Codium fragile ssp. fragile) and a native kelp (Saccharina longicruris) through 2 trophic levels in an ...

  • Invasion-mediated shifts in the macrobenthic assemblage of a rocky subtidal ecosystem 

    Kelly, Jennifer R., Robert E. Scheibling, and Toby Balch. 2011. "Invasion-mediated shifts in the macrobenthic assemblage of a rocky subtidal ecosystem." Marine Ecology Progress Series 437: 69-78. doi:10.3354/meps09284
    We tracked changes in community composition that occurred with state shifts in the rocky subtidal ecosystem in Nova Scotia, Canada, from 1992 to 2008. At the beginning of our study, a dense aggregation of sea urchins was ...
