  • Coastal food web structure, carbon storage, and nitrogen retention regulated by consumer pressure and nutrient loading 

    Worm, B., HK Lotze, and U. Sommer. 2000. "Coastal food web structure, carbon storage, and nitrogen retention regulated by consumer pressure and nutrient loading." Limnology and Oceanography 45(2): 339-349.
    By factorial field experiments we analyzed the relative effects of increased nutrient (N+P) loading and natural grazing pressure on species composition, carbon storage, and nitrogen retention in the Baltic Sea littoral ...

  • Complex interactions of climatic and ecological controls on macroalgal recruitment. 

    Lotze, Heike K., and Boris Worm. 2002. "Complex interactions of climatic and ecological controls on macroalgal recruitment.." Limnology and Oceanography 47(6): 1734-1741.
    Little is known about the cumulative effects of multiple (>2) environmental controls on species performance and interactions in aquatic ecosystems. We asked how changes in climatic (temperature, ultraviolet radiation) and ...

  • Effects of eutrophication, grazing, and algal blooms on rocky shores 

    Worm, Boris, and Heike K. Lotze. 2006. "Effects of eutrophication, grazing, and algal blooms on rocky shores." Limnology and Oceanography 51(1): 569-579.
    Eutrophication can profoundly change rocky shore communities. These changes often cause the replacement of perennial, canopy-forming algae such as Fucus spp. with annual, bloom-forming algae such as Enteromorpha spp. ...

  • Strong bottom-up and top-down control of early life stages of macroalgae 

    Lotze, Heike K., Boris Worm, and Ulrich Sommer. 2001. "Strong bottom-up and top-down control of early life stages of macroalgae." Limnology and Oceanography 46(4): 749-757.
    In contrast to most pelagic primary producers, benthic macrophytes pass through morphologically distinct life stages, which can be subject to different ecological controls. Using factorial field experiments, we investigated ...
