Estuarine meiofauna communities have been only recently considered to be good indicators of ecological quality, exhibiting several advantages over macrofauna, such as their small size, high abundance, rapid generation times and absence of a planktonic phase. In estuaries we must account not only for a great natural variability along the estuarine gradient (e.g. sediment type and dynamics, oxygen availability, t...

Do nematode and macrofauna assemblages provide similar ecological assessment information? To answer this question, in the summer of 2006, subtidal soft-bottom assemblages were sampled and environmental parameters were measured at seven stations covering the entire salinity gradient of the Mondego estuary. Principal components analysis (PCA) was performed on the environmental parameters, thus establishing differ...
Estuarine meiofauna communities have been only recently considered to be good indicators of ecological quality status, in contrast with macrofauna which is widely used in the assessment and monitoring of aquatic systems. Meiofauna features, such as their small size, high abundance, rapid generation times and absence of a planktonic phase, make these assemblages potential target indicators. In estuaries, we must...
With the implementation of the European Water Framework Directive there is the need to develop assessment tools based on biological data, which are adequate for all European aquatic systems. Macrofauna communities have traditionally been used to assess and evaluate ecological integrity. However, meiofauna communities can also suitably reflect the ecological conditions present in a particular system. Free-livin...
To improve nematode’s knowledge in the Mondego estuary (Portugal), the temporal and spatial variations of subtidal free-living marine nematodes communities (density, diversity and trophic structure) along the entire estuarine gradient (freshwater to euhaline areas) were seasonally studied (2006 to 2009). Since 1980, the hydromorphological, physicochemical and ecological responses of the system to both natural a...
