Comparing production and life-history traits of a key amphipod species within and between estuaries under different levels of anthropogenic pressure.

Popis výsledku v původním jazyce

Inter-population variability may arise as a response to adverse natural and anthropogenic stressors. The dynamics of a key amphipod species (Echinogammarus marinus) was followed during approximate to 1-year at its southerly range (NW Portugal), in three estuaries with different levels of anthropogenic pressure (High Ave estuary., Moderate Mondego estuary., Low Minho estuary). We hypothesised that E. marinus populations would present lower production and fitness, and higher intersexuality incidence with increasing anthropogenic pressure. According to a GAM model explaining approximate to 70% of the observed variability, E. marinus biomass depends on temperature, organic matter, Fucus area and time of the year. Significant differences were found between the gammarid biomass in Minho and Mondego estuaries and within sites from the same estuary. As expected, Ave estuary exhibited the lowest average annual production, abundance and fecundity rates. However, the highest average production was found in Mondego and not in Minho estuary, although the turnover ratio (P/B) of both estuaries was very similar.
