SynopsisPotential coexistence of the native Yaqui topminnow, Poeciliopsis occidentalis sonoriensis, with introduced mosquitofish, Gambusia affinis, was examined in spring pools and streams in San Bernardino National Wildlife Refuge, southeastern Arizona. Poeciliopsis never exceeded 12% of total poeciliid numbers in a spring pool where Gambusia was present. Body size, fecundity and reproductive effort of Poeciliopsis were significantly higher in this pool than in similar spring pools where… 
Captive Breeding of Endangered Yaqui Topminnow and Yaqui Chub for Recovery Purposes
TLDR
Yaqui topminnow Poeciliopsis occidentalis sonoriensis and Yaqui chub Gila purpurea, two federally endangered fishes from the Rio Yaquo basin, were propagated by various methods and success was only achieved after the water was chilled to 17°C for 30 d and adjusted to 21°C over 14 d.
A newly identified population of Gambusia affinis (Baird and Girard, 1853), a non-native invasive species, in Lake Kenyir, Malaysia: implications for management
TLDR
This species was recently identified in Lake Kenyir, one of the largest impoundments in South East Asia, using DNA barcoding and found to cluster with G. affinis but not with monophyletic clades of either G. holbrooki or P. reticulata thus confirming species identity.
Growth, Body Condition, Reproduction and Survival of Stocked Barrens Topminnows, Fundulus julisia (Fundulidae)
TLDR
The hypothesis that mosquitofish predation on larval Barrens topminnows was the primary mechanism in failed reintroductions and is the greatest threat to wild and reintroduced populations of this imperiled species is supported.
Eastern mosquitofish resists invasion by nonindigenous poeciliids through agonistic behaviors
TLDR
The results suggest that eastern mosquitofish may limit invasion success in Florida and actively drove swordtails from cover, which could expose non-native fish to other predators under field conditions.
Interaction between the introduced eastern mosquitofish and two autochthonous Spanish toothcarps
TLDR
In aquaria, adults and young-of-the-year (YOY) of both Spanish toothcarp Aphanius iberus and Valencia hispanica received more aggression in the presence of eastern mosquitofish Gambusia holbrooki, and aggression almost disappeared at low water temperatures.
Interaction between the introduced eastern mosquitofish and two autochthonous Spanish toothcarps
TLDR
In aquaria, adults and young-of-the-year (YOY) of both Spanish toothcarp Aphanius iberus and Valencia Toothcarp Valencia hispanica received more aggression in the presence of eastern mosquitofish Gambusia holbrooki, and aggression almost disappeared at low water temperatures.
Habitat and life history differences between two species of Gambusia
TLDR
There was no difference between species in reproductive effort per brood, but they differed in investment strategy, which reflects a tradeoff between individual productivity and differential mortality rates in different environments.
The role of gape-limitation in intraguild predation between endangered Mohave tui chub and non-native western mosquitofish
TLDR
Intraguild predation in this study system is size-structured based on gape-size limitation and may have some conservation implications for the recovery of endangered Mohave tui chub.
An invasive fish species within its native range: community effects and population dynamics of Gambusia affinis in the central United States
TLDR
Overall, within its native range, Gambusia affinis does not appear to impact negatively on the assemblages in which it occurs, possibly due to fluctuations in its density, and population information from long-term studies can help to form the basis of prudent, cost-effective management strategies for invasive organisms.
Plague Minnow or Mosquito Fish? A Review of the Biology and Impacts of Introduced Gambusia Species
Gambusia affinis and G. holbrooki, introduced worldwide from eastern North America, are collectively the most abundant, widespread freshwater fish in the world, which is not surprising because they

Attempted Chemical Renovation of an Arizona Springbrook for Management of the Endangered Sonoran Topminnow
TLDR
The Gila topminnow (Poeciliopsis occidentalis), an endangered poeciliid, rapidly declined in two Arizona springbrooks after colonization by non-native mosquitofish, leading to local extinction of the native fish.
Life History Patterns of Gambusia marshi (Poeciliidae) from Cuatro Ciénegas, Mexico@@@Life History Patterns of Gambusia marshi (Poeciliidae) from Cuatro Cienegas, Mexico
TLDR
Environmental and genetic contributions to morphological evolution in ciscoes (Coregoninae) of the Great Lakes and the genetic structure of populations is studied.
PREDATION AND SPECIES REPLACEMENT IN AMERICAN SOUTHWESTERN FISHES: A CASE STUDY
TLDR
An experimental analysis of mechanisms involved in replacement of a native Sonoran Desert fish by a non-native species is reported, and losses of other southwestern fishes via exotics are discussed.
Conservation Genetics of Endangered Fish Populations in Arizona
TLDR
Genetic diversity in remnant populations of the Sonoran topminnow Poeciliopsis occidentalis from Arizona is compared with that in populations from Sonora, Mexico, where the fish is widespread and abundant.
DIEL FEEDING CHRONOLOGIES IN TWO SONORAN DESERT STREAM FISHES, AGOSIA CHRYSOGASTER (CYPRINIDAE) AND PANTOSTEUS CLARKI (CATOSTOMIDAE)
Diel feeding chronologies in two desert fishes, Agosia chrysogaster (longfin dace) and Pantosteus clarki (Gila mountain sucker), were determined by examining the foregut contents of fishes taken from
Feeding interrelations of native fishes in a Sonoran Desert stream
TLDR
Abundance of invertebrates in Aravaipa Creek, coupled with marked spatial partitioning of habitat by fishes present, seemingly precluded severe interspecific interactions for food.
Effects of Abiotic Disturbance on Coexistence of Predator-Prey Fish Species
TLDR
It is predicted that introduced G. affinis populations would incur greater losses during Southwestern floods than would native P. occidentalis populations, and this hypothesis is consistent with data from a variety of other Arizona aquatic systems containing communities of native prey and introduced predatory fishes.

TLDR
Populations of this abundant and successful cyprinid in Sonoran Desert streams may play an important role in ecosystem nitrogen dynamics and rapid recycling of usable nitrogen to primary producers is significant in this nitrogen limited stream ecosystem.
Fitness differences among remnant populations of the endangered sonoran topminnow.
TLDR
Four correlates of fitness were measured in three stocks of the endangered Sonoran topminnow, Poeciliopsis occidentalis, from Arizona to emphasize the need for genetic as well as demographic information for the development of comprehensive species recovery programs.
