Different characteristics of the estuarine environments (i.e. geo-morphological, hydrographical, climatic or chemical ones) strongly condition the biodiversity development within those systems (Harrison 2004). So, the range of values of the different involved parameters (temperature, salinity, pH, dissolved oxygen, inorganic nutrients, organic matter, etc) as well as their corresponding seasonality or unexpected variations would directly determine the scenario where the whole biological processes will occur also including populations movement along different spatial gradients due to physiological problems (Laprise and Dodson 1994). In addition the distribution and availability of non-conservative constituents such as oxygen, nutrients or organic carbon fully condition the productivity ability of the system, and consequently its potential transference of energy to higher trophic levels (Cantoni et al. 2003, Rydberg et al. 2006).
