| description |
Previous work has highlighted the critical role of macroalgal productivity and dynamics in supporting and structuring marine food webs. Spatio-temporal variability in macroalgae can alter coastal ecosystems, a relationship particularly visible along upwelling-influenced coastlines. As a result of its equatorial location and nutrient rich, upwelling-influenced waters, the Galápagos Archipelago in the East Pacific, hosts a productive and biodiverse marine ecosystem. Reports and collections of macroalgae date back to the Beagle voyage, and since then, more than three hundred species have been reported. However, their ecology and functional role in the ecosystem is not well understood. According to various disparate and in part anecdotal sources of information, abundant and diverse communities exist in the Western regions of the archipelago, the North is essentially barren, and in the central/South abundance and distribution is variable and less well defined. Both oceanographic conditions and herbivore influence have been theorized to cause this pattern. Extensive changes in macroalgal productivity and community composition have occurred during strong ENSO events, and subsequent declines in marine iguana (an endemic and iconic grazer) populations have been linked to these changes. Iguanas are only one species of a diverse and abundant group of marine grazers in the system, highlighting the potentially important role of macroalgal productivity in the marine food web. This review represents a first compilation and discussion of the available literature and presents topics for future research. |

La variabilidad espacio temporal de las macroalgas puede alterar ecosistemas costeros, particularmente visibles a lo largo del perfil costero en zonas de proliferación. Como resultado de su ubicación ecuatorial y riqueza en nutrientes, además de eventos de proliferación, el Archipiélago de Galápagos en el Pacífico Oriental acoge un productivo y biodiverso ecosistema marino. Informes y recolección de macroalgas se remontan desde el viaje del Beagle, y desde entonces se han informado más de trescientas especies. No obstante, su función ecológica en el ecosistema no ha sido bien comprendida. Según diversas fuentes de información y en parte anecdóticas, existen abundantes y diversas comunidades de macroalgas en las regiones occidentales del archipiélago, el norte es sustancialmente estéril, y en el centro/sur la abundancia y distribución es variable y menos definida. Tanto las condiciones oceanográficas y la influencia de herbívoros han sido teorizadas para causar este patrón. Grandes cambios en la composición de la productividad y comunidad de macroalgas se han producido durante eventos ENOS fuertes y subsecuentemente han provocado la disminución de poblaciones de iguana marina (herbívoro endémico e icónico) y han sido vinculados a estos cambios. Las iguanas marinas son sólo una de las especies de un grupo diverso y abundante de herbívoros marinos en el sistema, destacando potencialmente el importante rol de la productividad de macroalgas en la cadena alimentaria marina. Esta revisión representa una primera recopilación y análisis de la literatura disponible y presenta temas para futuras investigaciones.Universidad de Costa Rica2017-03-01info:eu-repo/semantics/publishedVersionArticleartículo originalhttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articleapplication/pdftext/htmlhttps://revistas.ucr.ac.cr/index.php/rbt/article/view/1813910.15517/rbt.v65i1.18139Revista de Biología Tropical; Vol. 65 No. 1 (2017): Volume 65 – Regular number 1 – March 2017; 375–392Revista de Biología Tropical; Vol. 65 Núm. 1 (2017): Volumen 65 – Número regular 1 – Marzo 2017; 375–392Revista Biología Tropical; Vol. 65 N.º 1 (2017): Volumen 65 – Número regular 1 – Marzo 2017; 375–3922215-20750034-774410.15517/rbt.v65i1reponame:Portal de Revistas UCRinstname:Universidad de Costa Ricainstacron:UCRenghttps://revistas.ucr.ac.cr/index.php/rbt/article/view/18139/28204https://revistas.ucr.ac.cr/index.php/rbt/article/view/18139/28205Derechos de autor 2017 Revista de Biología Tropicalhttp://creativecommons.org/licenses/by/4.0acceso abiertohttp://purl.org/coar/access_right/c_abf2info:eu-repo/semantics/openAccess2022-06-09T18:02:38Zoai:portal.ucr.ac.cr:article/18139Portal de revistashttps://revistas.ucr.ac.cr/Universidadhttp://www.ucr.ac.crhttps://revistas.ucr.ac.cr/index.php/index/oaijorge.polanco@ucr.ac.crCosta RicaNo aplicaNo aplicaNo aplicaopendoar:2025-08-13T10:17:54.804Portal de Revistas UCR - Universidad de Costa Ricafalse |
