THE SONORAN TOPMINNOW (POECILIOPSIS OCCIDENTALIS) AND THE MOSQUITOFISH (GAMBUSIA AFFINIS): A TEST OF EMIGRATORY BEHAVIOR

Dean, Sheila Ann January 1987 (has links)
In experimental pools open to emigration, mosquitofish (Gambusia affinis) resided at higher densities than topminnow (Poeciliopsis occidentalis). When Gambusia were introduced to Poeciliopsis pools, all topminnow maintained residency. Only 11% of the Gambusia emigrated from the mixed populations before the plant cover was removed; with no cover, 59% left. A significant number of Gambusia in single species pools also responded to a loss of cover by emigrating. Continuing residency of Poeciliopsis after introduction of Gambusia supports findings that displacement by mosquitofish is not an immediate process. Frayed fins on resident topminnow suggest short-term agonistic interactions. Coexistence of an exotic species (Gambusia) and an endangered desert fish (Poeciliopsis) may depend on the complexity, or spatial variation, of the Southwest's few remaining cienegas. The opportunity to disperse from pools in these habitats may be an important factor in Poeciliopsis survival; such emigratory behavior can be tested in open experimental systems.

BEHAVIORAL INTERACTIONS BETWEEN DESERT PUPFISH (CYPRINODON MACULARIUS) AND MOSQUITOFISH (GAMBUSIA AFFINIS) IN SYSTEMS OPEN TO EGRESS.

JENNINGS, MARK RUSSELL. January 1986 (has links)
Varying numbers of adult desert pupfish (Cyprinodon macularius) and mosquitofish (Gambusia affinis) were introduced separately into experimental habitats open to egress to determine resource requirements for each species and the relation between numbers and resources. Laboratory environments in which "voluntary" colonization was achieved, were created for both species. Results indicated that both species have the innate ability to regulate numbers in their respective populations to available resources via emigration. The number of resident fish varied directly with experimental reductions of cover. When adult mosquitofish were introduced into open tanks with established populations of adult desert pupfish in habitats containing constant resources, there was no significant change in population size for either species as compared to single species populations over a 5-day period. Adult desert pupfish and mosquitofish are able to coexist successfully in habitats open to egress for 5 days because they utilize available resources in very different ways and the number of fish that become residents do not go beyond resource limits. These data suggest that replacement of desert pupfish by mosquitofish in the American Southwest is a phenomenon that is the result of more long-term interactions between all life stages of the species and may be more likely to occur in environments of low complexity and closed to egress.
