Non‐native fishes are often blamed for exerting adverse ecological impacts on native fishes,
but the evidence is circumstantial and the true impacts remain largely unknown. This …

Abstract The Iberian Peninsula contains a highly endemic freshwater ichthyofauna that is
being homogenized and threatened by an increasing number of non-native fishes. Here, in …

This review summarizes the mechanism of Cl− active secretion and its regulation in
estuarine teleost fish. Small estuarine fish such as the killifish, Fundulus heteroclitus, forage …

Killifish are ecologically important components of salt marsh ecosystems, but no studies
have determined the importance of locally produced versus allochthonous food sources on …

We review the general theory regarding habitat selection in fishes and integrate this theory
with recent data to evaluate habitat selection by marsh fishes. Models of habitat selection in …

We studied the ichthyofauna of the Castro Marim salt marsh based on monthly sampling
surveys at five sites between September 2000 and August 2001. Sampling took place at …

Biological invasions are a major threat to global freshwater biodiversity. Competition is a
frequent negative interaction between non‐native and native species, and this process is …

Metabolic depression is relatively uncommon among the fishes with the greatest number of
species exhibiting dormancy as embryos. Dormancy in fish embryos is largely associated …

Embryos of the marine killifish Fundulus heteroclitus are adapted to survive aerially.
However, it is unknown if they are able to control development under dehydration …

The Guadalquivir River Basin is one of the largest in the Iberian Peninsula and has a
remarkable freshwater biodiversity. Although many studies on hydrological regimes or water …
