“…We were unable to assess the relationship between plasticity of life history patterns and the area of the river basin and estuary, continental platform width or river discharge. These factors are among the main factors influencing the structure of estuarine fish assemblages (Nicolas et al 2010) and flounder juvenile recruitment (Martinho et al 2009). The inter-annual variability of river discharge may be an indirect driver of flounder life history plasticity, probably due to its control in setting estuarine productivity (Whitfield 1994, Loneragan & Bunn 1999 and in influencing the rate of direct and indirect recruitment of fishes in estuaries (Chícharo et al 2001).…”

European flounder Platichthys flesus life history patterns were investigated in 3 basins along a latitudinal gradient (Minho, N Portugal; Gironde, SW France; Seine, N France). We used coupled Sr:Ca and Ba:Ca otolith signatures and microstructure to retrospectively determine habitats occupied by flounder during their life, including early larval ontogeny. Flounder exhibited high life history plasticity among and even within basins, apparent by the diversity of habitats used during larval ontogeny and throughout their lives, and by the age at which flounder migrated to freshwater. Egg signatures probably had a strong maternal influence, and our interpretation suggests that flounder spawned and/or hatched predominantly in brackish waters in the Minho, while in the Gironde and Seine, flounder spawned and/or hatched either in coastal, brackish or freshwater environments. The freshwater egg signature was most frequent in the Seine. These interpretations contradict the current general assumption that flounder spawn exclusively in coastal waters. During pre-metamorphosis and metamorphosis, flounder were predominantly in brackish waters in the Minho, while in the Gironde and Seine, they were mainly in coastal and freshwater environments, respectively. The diversity of flounder life histories (LH) (i.e. sequence of habitat residence: freshwater, brackish or coastal) after metamorphosis was similar between the Minho (LH = 13), Gironde (LH = 13) and Seine (LH = 14) basins. The age at which flounder migrated to freshwater also varied among sites, at an earlier age in the Minho and Gironde (< 0.5 yr old) than in the Seine, where flounder migrating from the coast into freshwater reached maximum frequencies at age 1.3 yr old. Thus, catadromy in European flounder may be facultative, and the factors influencing flounder high LH plasticity deserve thorough research.

“…This temporal variability could be attributed to geographical differences in the environmental factors (water temperature, hydrodinamics, etc.) that regulate fish reproduction and inward migration periods of larvae and juvenile individuals (Martinho et al 2009). …”

The fish community that inhabits shallow littoral areas of the Mar Menor coastal lagoon was studied seasonally. Three different habitat types were compared: deep sandy habitats, vegetated habitats and shallow muddy habitats. The results indicated that the dominant fish families in the lagoon were Mugilidae, Gobiidae, Sparidae and Atherinidae. In general, vegetated habitats and shallow muddy habitats showed higher fish abundance, biomass and fish diversity than deep sandy habitats. Moreover, fish community structure differed significantly among habitats. Vegetated habitats and shallow muddy habitats seems to play an important nursery role, mainly for marine migrant species of the Mugilidae and Sparidae families, and constituted essential habitats for species of conservationist interest such Aphanius iberus and Syngnathus abaster. Deep sandy habitats were dominated by the resident goby Pomatoschistus marmoratus. These habitat-related differences are probably related to variations in structural complexity.

“…Costa et al, 2007;Gillson et al, 2009;Martinho et al, 2009), with consequent repercussion on the production levels , as observed by the increased production of Pomatoschistus microps in the years with higher precipitation levels. In general, higher river flow is responsible for an increased transport of organic matter towards estuaries, inducing an increase in primary and secondary production that provides higher food availability for fishes (Costa et al, 2007;Baptista et al, 2010;Dolbeth et al, 2010).…”

“…These impacts can be induced by the alterations in local climate patterns such as temperature, freshwater flow, wind, tidal circulation and currents (e.g. Henderson and Seaby, 2005;Martinho et al, 2009), or by changes in large-scale factors such as North Atlantic Oscillation (NAO) and sea surface temperature (SST) (Attrill and Power, 2002;Vinagre et al, 2009). In addition, local stochastic events such as weather extremes (e.g.…”

“…Estuarine fish populations are highly dynamic and characterized by changing levels of recruitment and migration (Costa et al, 2002), being highly affected by hydrological parameters and climate (Costa et al, 2007;Martinho et al, 2009). In particular, fish dynamics, growth and production of estuarine ecosystems seem to be strongly affected by altered hydrology patterns, which can be regulated by floods and drought events (Whitfield, 2005;Dolbeth et al, 2008aDolbeth et al, , 2010Baptista et al, 2010).…”

a b s t r a c tLarge-scale and local climate patterns are known to influence several aspects of the life cycle of marine fish. In this paper, we used a 9-year database (2003e2011) to analyse the populations of two estuarine resident fishes, Pomatoschistus microps and Pomatoschistus minutus, in order to determine their relationships with varying environmental stressors operating over local and large scales. This study was performed in the Mondego estuary, Portugal. Firstly, the variations in abundance, growth, population structure and secondary production were evaluated. These species appeared in high densities in the beginning of the study period, with subsequent occasional high annual density peaks, while their secondary production was lower in dry years. The relationships between yearly fish abundance and the environmental variables were evaluated separately for both species using Spearman correlation analysis, considering the yearly abundance peaks for the whole population, juveniles and adults. Among the local climate patterns, precipitation, river runoff, salinity and temperature were used in the analyses, and North Atlantic Oscillation (NAO) index and sea surface temperature (SST) were tested as large-scale factors. For P. microps, precipitation and NAO were the significant factors explaining abundance of the whole population, the adults and the juveniles as well. Regarding P. minutus, for the whole population, juveniles and adults river runoff was the significant predictor. The results for both species suggest a differential influence of climate patterns on the various life cycle stages, confirming also the importance of estuarine resident fishes as indicators of changes in local and large-scale climate patterns, related to global climate change.
