| description |
The main environmental variables determining the community structure and the functioning of Mediterranean shallow lentic ecosystems are described. These ecosystems are characterized by the unpredictability of their water inputs and the high variability in their water level and physical and chemical composition. Variations in flooding, salinity, and water turnover are determinant in species composition and nutrient dynamics. Taxon-based and size-based approaches to the study of the community structure of aquatic organisms that colonise these ecosystems are also compared. The conventional taxonomic approach, based on the determination of species composition, has been used for the identification of patterns in species richness, distribution and temporal dynamics, and for ecological requirements of species and their potential use as ecological indicators. This taxonbased approach has been compared with a size-based approach, where individuals are classified by their size. Size-based approach gives complementary information about community structure and dynamics, especially when communities are dominated by a single species. The use of size diversity combined with species diversity is suggested for a more complete understanding of community structuring in this type of ecosystem. Detailed examples of two Mediterranean shallow lentic ecosystems, the salt marshes of the Empordà wetlands and the Espolla temporary karstic pond, which differ in hydrology and water origin, are used to discuss the suitability of these different approaches. |

Se describen aquí las principales variables ambientales que determinan la estructura de la comunidad y el funcionamiento de estos ecosistemas. Variaciones en la inundación, la salinidad y la tasa de renovación del agua son determinantes en la composición de especies y en la dinámica de nutrientes. Se comparan también aproximaciones al estudio de la comunidad basadas en la composición taxonómica con las basadas en la distribución de tamaños. La aproximación taxonómica convencional, basada en la determinación de la composición de especies, es adecuada para la identificación de patrones en la distribución y en la dinámica temporal de la especies, así como para el análisis de los requerimientos ambientales de las diferentes especies y su uso potencial como indicadores ecológicos. Esta aproximación taxonómica se ha comparado con otra aproximación basada en el tamaño corporal, donde los individuos se clasifican por su tamaño. La aproximación basada en el tamaño proporciona información complementaria de la estructura y dinámica de las comunidades, especialmente cuando en estas comunidades hay una especie dominante. Se sugiere el uso combinado de una diversidad de tamaños y una diversidad de especies para una comprensión más completa de la estructuración de las comunidades en este tipo de ecosistemas. Para discutir si estas diferentes aproximaciones son o no adecuadas, se presentan datos de dos ecosistemas mediterráneos leníticos y someros: las marismas de Aiguamolls de l'Empordà y la laguna de Espolla, una surgencia cárstica de inundación temporal. 22006-01-0120062006-01-01Articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfhttps://ddd.uab.cat/record/27918reponame:Dipòsit Digital de Documents de la UABinstname:Universitat Autònoma de BarcelonaInglésengopen accesshttp://purl.org/coar/access_right/c_abf2Aquest material està protegit per drets d'autor i/o drets afins.
