The objective of this study was to determine the species composition, home range, and sex ratio of selected small mammals inhabiting three habitat types: upland aspen (Populus spp.) forest, adjacent wet meadow, and the ecotonal area between them. This research was carried out at Itasca State Park, Minnesota from June through August of 1992. Longworth live traps and pitfalls were used in tandem in a 10 x 10 grid with 10 meter spacing. Home range was estimated using the computer program "Home Range."Population densities were calculated using the Schnabel index. Eleven species of small mammals representing 6 families, and 2 orders were captured during 2,384 trap nights. Home range estimates were lower than that reported in the literature. Possible explanations are discussed. Density estimates were similar to that reported in the literature. Distribution of small mammals was affected by many factors including, food, cover, moisture, vegetation, and predators. Clethrionomys gapperi was the most abundant species in the aspen forest. Microtus pennsylvanicus were most common in the wet meadow. Peromyscus maniculatus were captured most often in the aspen forest. Insectivores were well represented with 3 different species. Sorex cinereus were more abundant in the aspen forest, but trap mortality prevented any recaptures. Three Sorex arcticus were captured, in the aspen and wet meadow. Blarina brevicauda was most common in the aspen forest.Item Determination of groundwater recharge and residence time in the Itasca moraine area, north-central Minnesota : a hydrogeochemical approach(1996) Kanuit, Shari AnnThe Itasca moraine, because of its size and relief, is suspected to influence the groundwater flow regime of north-central Minnesota by serving as a major recharge area driving regional flow. This study uses hydrogeochemistry to determine the spatial distribution of recharge and discharge areas in the context of previously-defined glacial landform assemblages. The chemical evolution of groundwater along a flowpath results in a difference in the chemistry of juvenile and evolved waters. The effects of topography on flow systems become apparent in the spatial analysis of juvenile and evolved chemistries. Topography influences the development of oxidizing zones and local flow systems which, in turn, affect the groundwater chemistry. The broad, flat outwash plain south of the moraine is found to be an area of high recharge, the hummocky stagnation complex an area of moderate recharge, and the low-lying, undulating till plain north of the moraine an area of discharge.Item Distribution of fish and temerature perference of yellow perch in the thermal plume of a power plant as determined by radio telemetry(1978) Ross, Marvin J.The movement patterns of four fish species, yellow perch (Perea flavescens), northern pike (Esox lucius), largemouth bass (Micropterus salmoides) and walleye (Stizostedion vitreum) were monitored with radio telemetry methods near the thermal discharge of a power plant, (6 T 15°c nominal). A minature temperature sensing transmitter and an automatic recording system were developed for use with yellow perch. Fish movements relative to depth, temperature, center of the home range, discharge point, and release location are examined. Near thermally altered areas northern pike exhibited the greatest amount of movement followed by yellow perch, walleye and largemouth bass. Except for largemouth bass, thermal experience was found to be transitory. An overa11 winter temperature preference of 5.4°c was determined for yellow perch. I concluded that temperature, when in concert with numerous other environmental variables, did not alter the distribution of yellow perch to that predicted on the basis of laboratory temperature preference studies.
