Coastal food web structure, carbon storage, and nitrogen retention regulated by consumer pressure and nutrient loading
Worm, Boris; Lotze, Heike K.; Sommer, U. (2000-03)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.; Worm, Boris (2002-11)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; Lotze, Heike K. (2006-01)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. ... -
How Many Species Are There on Earth and in the Ocean?
Mora, Camilo; Tittensor, Derek P.; Adl, Sina; Simpson, Alastair G. B.; Worm, Boris (2011-08)The diversity of life is one of the most striking aspects of our planet; hence knowing how many species inhabit Earth is among the most fundamental questions in science. Yet the answer to this question remains enigmatic, ... -
Strong bottom-up and top-down control of early life stages of macroalgae
Lotze, Heike K.; Worm, Boris; Sommer, Ulrich (2001-06)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 ...
