Issue Date: | 2004 | Publisher: | 0018-8158 | Journal: | Hydrobiologia | Abstract: | We sampled 36 coastal rocky reefs throughout the overall Canarian Archipelago and consider (1) the daily macroalgal consumption of the long-spined sea urchin Diadema antillarum and (2) the daily net production of macroalgae along temperate rocky-substrates, to provide evidence that Diadema antillarum plays an important role in the structure of the shallow benthic environment of the eastern Atlantic. D. antillarum was found to be the main key-herbivore species, as it controls by its own the algal assemblages, with negligible contribution of other grazing species. | URI: | http://hdl.handle.net/10553/49626 | ISSN: | 0018-8158 | DOI: | 10.1023/B:HYDR.0000026599.57603.bf | Source: | Hydrobiologia [ISSN 0018-8158], v. 519, p. 211-214 |
