“…catifornicus caused mortality of M. mu.Hutus nestlings (Blaustein 1980). Briese and Smith (1973) suggested that competition for burrow sites was the most important factor when introduction of Pe. potionotus caused the extinction of an established M. muscutus population.…”

This paper tests the hypothesis that Pseudomys novaehollandiae shows competitive superiority over Mus musculus. Experimental removals of P. novaehollandiae on four 1 ha treatment plots and additions on a further four 1 ha plots show significatii effects of interspecific competition when compared to two I ha unmanipulated control plots. Significant effects of P. novaehollandiae populations on ihe abundance ofM. musculus populations were observed for number of captures/day, abundance/ trapping session and for the recruitment of new individuals over the post-removal period, thus allowing rejection ofthe null hypothesis in each case. There was an apparent ceiling on ihe total rodent abundance which is indicative of a resource limitation. The resource in short supply appears to be space, but it is not clear if ihe competition is for food or shelter resources contained within such space or for the space per se, but the latter seems less likely.The confirmation of this interspecific competition supports the inferences drawn from a considerable amount of indirect evidence, largely descriptive, obtained from previous studies in the Myall Lakes National Park. This study also shows that competition is one of the mechanisms controlling the replacement of species in the succession following disturbance and lends support to the habitat accommodation model proposed for such succession. These points support previous statements on the importance of interspecific competition as a determinant of the structure of these small-mammal communities.

“…This difference provides further evidence for the intraspecific competition and the associated establishment of a male dominance hierarchy associated with centralized-grid populations. Delong (1967), Newsome (1969a), and Briese and Smith (1973) found that the availability of homesites is important in the control of house-mouse densities. While the availability of food may not have been a limiting factor for centralized-grid individuals during the early months of this study (June through September), the availability of homesites did appear to play an important role in social organization, i.e., 50% of the centralized-grid females and 60% of the decentralized-grid females were captured at food depots 1 mo following introduction.…”

Eight 0.1—ha small—mammal enclosures were stocked with house mice (Mus musculus) on 6 June 1975. Mice were allowed to populate all grids until late December 1975. Four of the grids contained a centralized food (corn) depot while the other 4 contained equally spaced decentralized depots. Peak densities were reached in all populations by 1 November 1975. Populations in centralized grids reached a mean peak density of °20 animals per grid while the mean peak density in the decentralized grid populations was °30 animals per grid. Decreases in the following population parameters were found in both grid types with increased population densities: reproduction, juvenile mortality, population growth rates, and average cohort weights at first month of trapping. The ♂ ♂ and ♂ ♂ in decentralized grids exhibited greater survivorship than did ♂ ♂ and ♀ ♀ in centralized grids, respectively. Corn consumption was greatest in all grids after mid—October. Animals in the decentralized grids utilized a greater percent of corn to fulfill their energetic requirements than did animals in the centralized grids throughout the study. In the decentralized grids ♂ ♂ and ♀ ♀ were found to have similar assimilation efficiencies no matter where they were trapped in the grids. However, animals from peripheral areas in centralized grids exhibited significantly lower assimilation efficiencies than did animals from food—depot locations. Uneven partitioning of food resources, compounded by high population density, has a greater depression effect on population growth and structure than does high density alone.

“…Exotic rodent species may compete with certain native species (Briese and Smith, 1973;Caldwell and Gentry, 1965;King, 1957;Thornton, 1971;Woods, 1989), and extinctions in oryzomine genera (taxa presently or formerly included in the genus Oryzomys-Honacki et aI" 1982) Megalomys, Nesoryzomys, and Oryzomys have been attributed, all or in part, to the introduction of R. raltus to the Antilles and Galapagos islands (Jackson, 1985;Thornton, 1971;Woods, 1989). No studies have documented the process, however.…”

The silver rice rat (Oryzomys argentatus), a rare endemic rodent, and the black rat (Rattus rattus), an exotic species, have coexisted for <500 years in the Florida Keys. Determination of fine8 scale movements and behavior, by use of neck-attached fluorescent dust dispensers, revealed the degree of overlap in use of space, and some food resources, in free-ranging animals. Food selection tests were conducted in the laboratory. Significant differences in vegetation association, behavior, arboreality, and diet were found. From estimates of spatial niche overlap based on four indices I suggested the differences were biologically insignificant; the average value of four estimators on the habitat-choice resource axis was 89%, higher than reported for 47 of 48 pair-wise comparisons of native rodent species. I suggest that silver rice rat populations may be jeopardized by the presence of black rats whose invasion was reported to have caused oryzomine extinctions in the Galapagos and Antilles islands.
