Life‐history patterns of the mosquito‐fish, Gambusia affinis, in the estuary of the Guadalquivir river of south‐west Spain
SUMMARY. 1. The age, growth and reproduction of the small, introduced fish Gambusia affinis (Baird & Girard, 1853) were studied in the estuary of the Guadalquivir river. 2. The life-span wasExpand

Morphometric study of the Iberian Aphanius (Actinopterygii, Cyprinodontiformes), with description of a new species
Morphometric variation in Aphanius iberus was analysed to demostrate the remarkable genetic divergence between Mediterranean and Atlantic population of Iberia. Four discrete morphotypes in males andExpand
