G. Bernardi et al., ORIGIN OF A SPANISH POPULATION OF FUNDULUS-HETEROCLITUS INFERRED BY CYTOCHROME-B SEQUENCE-ANALYSIS, Journal of Fish Biology, 47(4), 1995, pp. 737-740
Fundulus heteroclitus in the estuary of the Guadalquivir River in sout
hern Spain competes with a native killifish, Aphanius iberus. Cytochro
me b sequence analysis shows that the Spanish individuals are derived
from the northern of two possible American populations of F. heterocli
tus. (C) 1995 The Fisheries Society of the British Isles.
