Multiple Captures Of Peromyscus Le Uco Pus: Social Behavior In A Small Rodent, James M. Novak Jan 1983

Multiple Captures Of Peromyscus Le Uco Pus: Social Behavior In A Small Rodent, James M. Novak

Faculty Research & Creative Activity

The capture of more than one individual in a live trap can often provide information on the social behavior of small mammals, but the conclusions drawn from these data will depend on the type of live trap used. Davis (1955) and Getz (1972) used multiple capture traps and analyzed their data with respect to attraction and repulsion of individuals both within and between different age and sex classes. Petersen (1975), Feldhamer (1977), Blaustein and Rothstein (1978), Jenkins and Llewellyn (1981) and Spencer et al. (1982) gained information on the formation of associations during foraging and dispersal from multip~ captures made …


Isolation And Identification Of Obligately Anaerobic Bacteria From Bovine Lung Abscesses, Steven Daniel Jan 1980

Isolation And Identification Of Obligately Anaerobic Bacteria From Bovine Lung Abscesses, Steven Daniel

Faculty Research & Creative Activity

For many years, the role of anaerobic bacteria in human diseasewas considered important only in such clostridial diseases as gas gangrene,botulism and tetanus. In the last 10 years, however, the developmentof new methods to isolate and identify anaerobic bacteria has establishedthe pathogenic role of non-sporeforming anaerobic bacteria in awide variety of clinical infections in humans. Bacteroides fragilis isnow known to account for approximately one-fourth of all anaerobicbacteria isolated from human clinical specimens.

Distribution And Relative Abundance Of Small Mammals In The Illini Forest Plantation, Urbana, Illinois, James M. Novak Jan 1978

Distribution And Relative Abundance Of Small Mammals In The Illini Forest Plantation, Urbana, Illinois, James M. Novak

Faculty Research & Creative Activity

The abundance and distribution of small mammals were analyzed for correlation with the vegetational characteris· tics of their habitat. Positive correlations were found for the number of mammals trapped per area trapped versus the total ground cover (r= .67, P< .05) and for the number of mammal species versus total ground cover (r= .73, P<.05). The habitat preferences of the three species trapped (short-tailed shrews B/,arina brevicauda. white-footed mice Peromyscus leucopuus, and meadow voles Microtus pennsylvanicus) showed a distinct distributional pattern for the species in relation to their habitats. The management of forest-tree plantations to achieve high densities during the seedling stage and the use of silvicultural practices that promote high shrub densities are suggested as inexpensive and natural control measures for injurious microtine rodents. Seedlings must be permitted to reach a sufficient height to remove the risk of the shrubs overtopping them.
