The desert pupfish
is a small (<75 mm total length), short-lived (2-year life span) species with broad tolerance to extreme environmental conditions (water temperatures approaching 45[degrees]C, dissolved oxygen concentrations as low as 0.
Such ecological partitioning could have resulted in part from the general preference of most species of pupfish
for quieter waters, which might have been reinforced by competition and predation by these cyprinids.
Examples of partnership agreements and programs that have precluded the need to list under the Endangered Species Act include the Pecos pupfish
(Cyprinodon pecosensis) in New Mexico and Texas, the Umpqua mariposa lily (Calochortus umpquaensis) in Oregon, and a California plant, the Cuyamaca Lake dowingia (Dowiningia concolor var.
Although these species were originally established at the zoo as refugia or research populations, the pupfish
and topminnow also provide the unexpected benefit of natural mosquito control for the zoo.
It is believed that this mining activity contributed to the endangered status of the spring-loving century plant (Centauriam namophilum), Ash Meadows gumplant (Grindelia fraxino-pratensis), Ash Meadows pupfish
(Cyprinodon nevadensis mionectes), and Ash Meadows speckled dace (Rhinichthys osculus nevadensis), and to the extinction of the Ash Meadows vole (Microtus montanus nevadensis; Soltz and Naiman, 1978; T.

historically occurred in the Pecos River system from the vicinity of Roswell in Chaves County, New Mexico, downstream to the Sheffield area in Pecos County, Texas.
(Cyprinodon macularius) In January 1997, personnel from the FWS Parker, Arizona, Fishery Resource Office, Arizona State University and the Upper Gulf of California and Colorado River Delta Biosphere, collected for desert pupfish
at sites in northern Sonora and Baja del Norte, Mexico.
Researchers discovered damage to some of the pupfish
similar to the effects of chronic alcoholism.
Status of the endangered Pecos gambusia (Gambusia nobilis) and Comanche Springs pupfish
(Cyprinodon elegans) in Phantom Lake Spring, Texas.
For example, western mosquitofish had a significant negative effect on the abundance and biomass of the threatened White Sands pupfish
(Cyprinodon lukirosa: Rogowski and Stockwell 2006).
The silver-coloured fish, Aphanius Dispar - also affectionately known as the Arabian pupfish
- feed on mosquito larvae, wiping them out before they can fly off in search of human prey.
The species of the pupfish
genus Aphanius Nardo, 1827 (Cyprinodontiformes) are widely distributed along the late period Tethys Sea coastlines (Smith et al.
