“…Thus, many of them have been abandoned or their use has changed with deleterious effects on biodiversity (Ortega et al, 2004;López et al, 2010) and, in particular, on the conservation of Mediterranean cyprinodontids. Due to species conservation concerns, several studies have recently increased our knowledge of the biological characteristics of the Iberian toothcarp, including feeding ecology (Alcaraz & García-Berthou, 2007), ecophysiology (Oliva-Paterna et al, 2007;García-Alonso et al, 2009), interactions with exotic species (Rincón et al, 2002;Caiola & De Sostoa, 2005) and ecological interactions (Casas et al, 2011;Compte et al, 2012). There are, however, few studies analysing the habitat preferences of Iberian toothcarp at the meso-, or microhabitat scale and no studies have been done in artificial systems such as salt exploitation wetlands.…”
