Habitat Use of Urban Bats in Springfield, Missouri
… II bat detector system was placed in a mosaic of habitats within Springfield, Missouri and surrounding rural areas in southern Missouri to compare the activity indices of nine bat species between urban and rural environments. A total of 1,876 echolocation call sequences was recorded, identified to …

Habitat Use by Beaver Along the Big Sioux River
Habitat utilization and lodge site selection by beaver (Castor canadensis) were investigated during 1985 and 1986 along the Big Sioux River in eastern South Dakota. Because livestock grazing has affected the number and size of trees available for beaver use, the study area was portioned into …

HABITAT USE BY SPRUCE GROUSE IN A FRAGMENTED SYSTEM
<p>The spruce grouse is a boreal obligate species that has been protected in Michigan since 1915 (Ammann 1963). Despite protection, the status of spruce grouse is uncertain in Michigan and other parts of the Midwest, and there have been few attempts at large-scale surveys or monitoring (Williamson …

Habitat use by nongame birds in central Appalachian riparian forests
I sampled bird densities and habitat characteristics along a gradient from a second-order stream to 454 m upland at 16 locations. Total bird density, species richness, and densities of 28 bird species were tested to determine whether riparian habitats influenced bird communities. Total bird density …

Movements and Habitat Use By Hen Pheasants During Brood Rearing
Land-use patterns characteristic of prime pheasant range in the Great Plains and prairie region have 50-75 percent of the land under cultivation according to Kimball et. al. (1956). Farmland is pheasant habitat, and the production of pheasants is therefore greatly influenced by farming practices. …

Factors Influencing Habitat Use By Breeding Waterfowl in South Dakota
… second in June, each year during 1973 and 1974. Habitat variables of each wetland and of each quarter section, respectively, were analyzed for each species of waterfowl through multiple regression analysis. Multiple regression equations had highest coefficients of determination for mallards (Anas …

Winter habitat use by mule deer in Idaho and Montana
… on an energy conservation strategy where they use habitats at lower elevations and on south facing slopes with adequate thermal or canopy cover. However, not all mule deer habitats are equivalent in components or weather conditions, which contribute to differences in habitat use patterns and …

Habitat use by fishes of the New River, West Virginia
… of the species and life stages in different habitat types were made from electrofishing collections and underwater fish counts. During midday, fish densities in edge pool and riffle habitats were comparable, but densities in edge pool habitat were significantly higher than densities in middle …

Using Motion-Triggered Cameras to Estimate Habitat Use by Collared Peccaries
Motion-triggered cameras (MTC) are used in a variety of wildlife research applications; however, few studies outline how to use MTC to collect reliable data on habitat use. Herein I outline how to use MTC for collecting reliable data on habitat use of collared peccaries (Pecari tajacu). Using MTC …

Post-fire vegetation and bird habitat use in piñon-juniper woodlands
Global climate change has caused fire activity and behavior to shift from historical norms due to hotter and drier conditions. Although the ecological effects of changing fire regimes have been explored in many systems, the resilience of some forest types, such as piñon-juniper, are often …

Mammalian habitat use along a residential development gradient in northern Colorado
… the impact of exurban development on mammalian habitat use, wildlife cameras were placed along a unique development gradient designed to capture landscape permeability in a rapidly growing rural region of Colorado. Multiple-season species occupancy and relative activity (frequency of detections) …

Habitat use and responses to odours by rodents in New Zealand
… combination of laboratory and field studies was used to examine the interactions between rodents, especially the role that odours play in regulating interspecific interactions. Knowledge of rodent ecology and interactions is required to manage populations of these pests effectively. Snap trapping …

Rainbow Trout (Oncorhynchus mykiss) Summer Habitat Use in Lake Spokane, Washington
… due to climate change, reducing thermal habitat for cold-water fish species. Rainbow Trout are sensitive to changes in their habitat and prefer water temperatures < 20 °C and DO levels ≥ 5.0 mg/L. The overarching goal of this study is to document Rainbow Trout movements in an environment …

White-tailed deer hunting and habitat use in Robert Allerton Park
… objectives were to investigate changes in deer habitat use and spatial clustering following 10 years of deer removal in RAP. I evaluated changes in annual deer counts within RAP’s three main habitat types, dry mesic upland forest, wet mesic floodplain forest and developed land using a …

Home range, habitat use, behavior, and morphology of the Gettysburg vultures
… cropland and urban areas. Nesting vultures only used caves within forested diabase rock formations. While feeding, birds preferred pasture and cropland and avoided forest and urban areas. Farm carrion was an important food resource for both species. Black vultures fed more on carrion greater than …

Densities, habitat-use, and mesopredator release of the ocelot in Belize
… I conducted remote camera surveys and sampled habitat within four protected areas: three broadleaf sites and one pine forest site. I measured ocelot activity and habitat-use with respect to the activity of jaguars and pumas at one broadleaf site and one pine forest site; additionally, I …

Habitat Use And Seasonal Activity Of Selected Snakes On John F. Kenned
… sampling of snake communities inhabiting four habitat types was conducted at John F. Kennedy Space Center, Brevard County, Florida from November 2002 through October 2003. Thirteen species (580 individuals plus 74 recaptures) plus one hybrid were captured. The three most commonly captured …
