This is because within the few species that have been thoroughly studied (e.g., Poecilia reticulata, Gambusia affinis, Brachyrhaphis rhabdophora), the species and populations evolved the same traits independently and as a response to the same environmental factors such as predation, stream velocity, or population density (Reznick and Endler, 1982; Johnson and Belk, 2001; Reznick et al., 2002; ZUniga-Vega et al., 2007).

Romero (1984, 1985) studied a small population of Astyanax mexicanus and Brachyraphis rhabdophora (Regan) that used both epigean and subterranean habitats over the course of the day.
Some species, such as Olomina Brachyrhaphis rhabdophora and the Bishop Olomina Brachyrhaphis episcopi, occur along an elevational and ecological gradient from lowland coastal streams to mountain headwaters, and therefore have populations that occur in vastly different environments (Johnson and Belk, 2001; Jennions and Kelly, 2002; Jennions and Telford, 2002).
rhabdophora in northern Costa Rica differ in terms of predation pressure, with low-elevation populations occurring with numerous piscivorous predators and highelevation populations devoid of piscivorous predators, typically due to the presence of barrier waterfalls that occur between high- and low-elevation populations (Jennions and Telford, 2002; Johnson and Belk, 2001).
