Is the bioproduction number a good index of the trophic state in Mediterranean wetlands?

Abstract: Key-words: sediment, trophic state, wetlands, bioproduction numberEutrophication is one of the major problems affecting water quality of inland waters. Therefore trophic state evaluation is essential for the conservation, the management and the application of possible future restoration measures. The main aim of this work was to assess the effect of different land uses in the drainage basins of the Mediterranean wetlands on the bioproduction number (BPN), an indicator of the wetland trophic state. For this, we… Show more

“…The main advantage of using BPN is that, while the application of indices based on water column parameters (see for example [84,85]) requires repeated seasonal monitoring to obtain the annual mean values, the reproducibility of the BPN method has shown constant BPN values every time, and thus only one sampling representing the spatial heterogeneity of the surface sediment is required [83]. However, some limitations have also been detected when using BPN in Mediterranean wetlands characterized by low sedimentary organic matter content [86]. Secondly, the lake sediment affects the chemical composition of the overlying water column, as it is a dynamic and active compartment where a great diversity of reactions and transformations lead to nutrients mobilization or retention.…”

“…La biomasa del fitoplancton en los mallines, evaluada a partir de la concentración de la clorofila a (chl-a), mostró en la mayoría de los casos valores menores a de 6 µg.L -1 (n=23), pero con un máximo de 32,5 µg. (Gilbert et al 2015).…”

“…En la mayoría de los mallines estudiados, el estado trófico estimado por el TSI PT es mucho más alto que el calculado a partir de TSI Cl , en coincidencia a lo documentado en otros estudios (Elmaci et al 2009, Jarosiewicz et al 2011, Vidović et al 2015. Esto ocurre porque la concentración de clorofila a es notablemente más baja a la esperada de acuerdo a la concentración de fósforo total (Gilbert et al 2015). Una de las probables causas de este fenómeno es que el nitrógeno puede actuar como nutriente limitante del fitoplancton y el fósforo encontrarse en exceso, de acuerdo a la relación N:P (Reddy y De Laune 2008, Sánchez-Carrillo et al 2010; otra causa importante es debida de la presencia de las macrófitas (Gilbert et al 2015).…”
