DEMISE OF AN INTRODUCED POPULATION OF THE SAILFIN MOLLY, POECILIA LATIPINNA, IN THE UPPER GUADALUPE RIVER OF CENTRAL TEXAS

摘要

Populations of the sailfin molly, Poecilia latipinna, are native to Mexico and the Rio Grande valley and coastal Texas. Other Texas populations are considered to be the result of introductions beyond the natural range for this species (Brown 1953; Hubbs et. al. 1991).
