Effects of extreme climate events on the macrobenthic communities’ structure and functioning of a temperate estuary

Patterns in estuarine macrofauna body size distributions: The role of habitat and disturbance impact

“…Nevertheless, evenness was higher in the mudflat and sandflat areas (Fig. 4B), mainly due to the dominance of Hydrobia ulvae in the Z. noltii beds (as detailed by Grilo et al, 2011). For all areas, there was a clear decline in the number of species during the pre-mitigation period.…”

“…Changes have been observed in the quality and quantity of primary and secondary production, with huge increases in macroalgal productivity, concomitant with decreases in seagrasses (Cardoso et al, 2010) and general impoverishment of the biotic communities Grilo et al, 2011;Leitao et al, 2007). A restoration and management programme was implemented in 1998 to control and reverse eutrophication and its main effects, which included experimental mitigation measures, such as hydrological management to increase circulation and diversion of nutrient-rich freshwater inflow to the estuary.…”

Efecto del tamaño de malla en los valores de densidad y biomasa de la comunidad bentónica estuarina del Estero de Punta Banda, Baja California

“…Dolbeth et al (2007) y Grilo et al (2011) han reportado disminuciones en las densidades de comunidades bentónicas debido a dichos factores ambientales, los cuales afecta en mayor medida a los organismos macrofaunales (Schwinghamer 1983), razón por la cual es posible atribuir a estos eventos físicos la disminución de organismos en el área evaluada (Fig. 2).…”

The use of an Estuarine System (Mondego estuary, Portugal) as Didactic Tool to incorporate Education for Sustainable Development into School Curricula

“…Those actions improved the hydrodynamic conditions in the South arm and diverted the nutrient loading. In addition to the anthropogenic pressures, the estuary has also been affected by the occurrence of natural extreme climatic events in the last years (Marques et al, 2007b;Martinho et al, 2007;Cardoso et al, 2008;Grilo et al, 2010;Dolbeth et al, 2011). As result there were recorded changes in the species distribution, dynamics, and changes in its structure and composition (Marques et al, 2007b;Baptista et al, 2010;Grilo et al, 2011;Nyitrai et al, 2012).…”
