Resumen
(ES)La región mediterránea incluye humedales diversos y con elevado valor ecológico. Están
caracterizados por fluctuaciones intra-interanuales en sus condiciones ambientales que provoca
cambios en las características limnológicas y, por ende, cambios en las comunidades zooplanctónicas.
En este contexto, planteamos como hipótesis: la comunidad zooplanctónica puede ser utilizada como
un elemento bioindicador para la determinación de futuro cambio global. Se seleccionaron siete
humedales mediterráneos temporales situados en el sureste de Península Ibérica. Se utilizaron dos
enfoques: correlaciones de Spearman y un análisis canónico de correspondencia (CCA), a partir de una
reducción simplista en las precipitaciones (75, 50 y 25%) tomando como referencia los datos del
período 2009-2010. Los resultados muestran que la clorofila, cobertura por macrófitos, área del
humedal, profundidad, materia orgánica y concentración de nitrógeno total, fueron las variables con
mayor influencia. Finalmente, se destaca el uso del zooplancton como un bioindicador ante futuros
escenario de cambio global.
(EN)The Mediterranean region includes a variety of wetlands with high ecological value. They are characterized by intra-interannual fluctuations in their environmental conditions that cause changes in the limnological characteristics and, therefore, changes in the zooplankton communities. In this context, we hypothesize: the zooplankton community can be used as a bioindicator element for the determination of future global change. Seven temporary Mediterranean wetlands located in the southeast of the Iberian Peninsula were selected. Two approaches were used: Spearman correlations and a canonical correspondence analysis (CCA), based on a simplistic reduction in rainfall (75, 50 and 25%) taking as reference the data from the 2009-2010 period. The results show that chlorophyll, macrophyte coverage, wetland area, depth, organic matter and total nitrogen concentration were the variables with the greatest influence. Finally, the use of zooplankton as a bioindicator in future scenarios of global change is highlighted.
