Abstract:
The introduced mosquitofish (Gambusia affinis holbrooki) is a pest species in Australia and has been implicated in the decline of populations of native fishes and anurans. However, few quantitative data exist regarding interactions between Gambusia and native aquatic fauna. We used replicated laboratory experiments to investigate predation by G. a. holbrooki on eggs, hatchlings and tadpoles of native (Limnodynastes ornatus) and non-native (Bufo marinus) anurans. Our aims were to determine (1) whether the susceptibility of anurans to predation by G. a. holbrooki changes during larval developmen

Abstract:
The closely related eastern mosquitofish (Gambusia holbrooki) and western mosquitofish (Gambusia affinis) have been introduced into many countries and collectively represent the most widely distributed freshwater fish in the world. We investigated genetic patterns associated with the spread of G. holbrooki in its introduced range in south-eastern Australia, by sampling 60 G. holbrooki populations (n = 1771) from major regions where G. holbrooki was initially introduced into Australia, and characterising the genetic diversity and population structure of G. holbrooki, using five polymorphic nucl

Abstract:
Mosquitoes ( Culex pipiens L., 1758) are important vectors for diseases of both wildlife and humans. Understanding how natural factors influence mosquito abundance may provide insights into the ecology of various diseases, as well as solutions to controlling disease vectors. One of the natural factors regulating mosquito distributions and population sizes is predation. A poorly understood source of natural mosquito predation is amphibians. We determined the mosquito consumption capability of two amphibians, adult Red-spotted Newts ( Notophthalmus viridescens viridescens (Rafinesque, 1820)) and

Clearing and staining of Gambusia holbrooki facilitated identification of juvenile fishes among the gut contents, and a feeding trial with captive Gambusia allowed assessment of gut transit time and degradation of melanotaeniid larvae.

These techniques, extending to 12 h the post-feeding interval in which fishes may be found and differentiated among Gambusia gut contents, were tested on 631 wild-caught Gambusia collected in eastern Australia; an ingested native fish could be identified in the gut of 18 Gambusia, and a c

Around 83 percent of the world's population live in light-polluted areas, of which 40 percent live in places that are continuously lit by “ALAN (Artificial Light at Night)”. The light pollution caused by “ALAN” is growing day by day.  Thus, the risk of environmental damage is growing in aquatic areas by increasing the “ALAN”. In this way, this research investigates the artificial light at night’s a “ALAN” effect on Gambusia Holbrooke “mosquitofish” in Iran. To obtain the ALAN data, we relied on the information from the

The Gambusia genus gathers about 45 species of small fishes colonizing freshwater. Since the earliest 20th century, it gained great interest in counteracting infections transmitted by mosquito flies.

Previous studies revealed their efficacy in eradicating many infectious diseases including malaria, but their biology and interest in oasian and semi-arid ecosystems are scarcely studied.

Native fish are threatened globally by invasive species, and management actions largely focus on detecting and eradicating invaders before they become established. However, once established, invaders might also be controlled by taking advantage of adaptations of threatened species to local conditions. This strategy was explored in dwarf galaxias (Galaxiella pusilla) a freshwater-dependent species of national conservation significance in Australia, threatened by invasive eastern gambusia (Gambusia holbrooki).

The impact of the presence of the introduced poeciliid Gambusia holbrooki on the Australian pseudomugilid Pseudomugil signifer was examined in open-air tank experiments. G. holbrooki profoundly affected the breeding of P. signifer. In the presence of G. holbrooki, P. signifer did not gain weight or grow in total length, ovarian weight and fecundity were greatly reduced, and the ovaries were morphologically undeveloped. No eggs of P. signifer were observed in tanks that also housed G. holbrooki. The results indicate that, at least in a captive situation, the presence of the exotic species had a

Mosquitofish (Gambusia holbrooki) are native to the southeastern United States but invasive elsewhere, and are dominant predators in many ecosystems that they inhabit. Information on dispersal behavior will help better understand and predict mosquitofish metapopulation dynamics and invasions. I experimentally tested dispersal behavior of individual mosquitofish under a range of laboratory conditions relevant to field situations. Preliminary experiments showed that gender, lighting conditions, hunger and acclimation time did not significantly affect net dispersal rate. Power analysis based on t

It has long been recognized that the ability to make numerical judgments predates the evolution of human language. In the last few decades, a large body of evidence has accumulated on numerical competence in mammal and birds, but little is known about the numerical abilities in lower vertebrates. The present research investigated numerical competence in fish, using both spontaneous choice test and training procedure. Results of free-choice test show that female mosquitofish seem to use two distinct systems for quantity discrimination; at the same time this study provides persuasive evidence

The eastern mosquitofish (Gambusia holbrooki) is one of the most widely distributed and invasive inland fish.

This thesis examines how temperature affects the competitive ability and life history traits of mosquitofish. We sampled mosquitofish along latitudinal gradients and along rivers and we found that mosquitofish in more favorable environments (i.e. low latitudes and downstream river reaches) had a higher reproductive effort and lower body
