Habitat Preferences and Food Habits of Striped Skunks in Eastern South Dakota
Habitat preferences of striped skunks (Mephitis mephitis) in Brookings County, South Dakota, were determined rom the relationship of nighttime roadside indices to 25 habitat variables of 277, 1-square mile plots. Winter tracking was also conducted. Skunks were collected on the study area in …

Early hominid habitat preferences in East Africa: Stable isotopic evidence from paleosols
… understand early hominid land-use patterns and habitat preference, the synchronic variation of hominid activity preserved in archaeological sites is examined in a diversity of floral microhabitats across two Early Pleistocene landscapes. In collaboration with landscape archaeology projects at …

Fish ecomorphology: predicting habitat preferences of stream fishes from their body shape
… morphology to predict membership of fishes in habitat guilds, their swimming performance, and habitat preference. Further, it considered methods for choosing a surrogate species to identify habitat of target species. Morphological discriminant functions were developed using morphological traits …

Habitat preferences of the eastern fence lizard, Sceloporus undulatus, in southwestern Virginia
Habitat preference of the eastern fence lizard, Sceloporus undulatus, was investigated in southwestern Virginia. Habitat features were measured at 158 lizard-centered plots and at paired random plots. Landscape-level variables, southerly aspect and mixed forest type, distinguished lizard-centered …

Habitat Preferences and Censusing of Waterfowl Broods On Stock Ponds In South Central South Dakota
… broods and to determine waterfowl brood habitat preferences. Results indicated that 72-8% of the broods present were censused by either technique alone. No differences were indicated between the 2 techniques when analyzed by species. For total brood counts, a significant (P<0.05) …

Generalist predators in reduced-tillage corn: predation on armyworm, habitat preferences, and a method to estimate absolute densities
The potential impact of generalist predators on armyworm mortality was evaluated in the field, through a predator removal study, and in the laboratory, through controlled feeding trials. The most common potential armyworm predators removed from the field included ground beetles (Carabidae), rove …

Determination of Habitat Preferences of Pronghorn (Antilocapra americana) on the Rolling Plains of Texas Using GIS and Remote Sensing
… (Antilocapra americana) in Texas. To investigate habitat utilization on the ranch, pronghorn were fitted with GPS/VHF collars and were released into pastures surrounded by a variety of fences to determine how fence types affected habitat selection. Habitat parameters chosen for analysis were …

Late Quaternary palaeoenvironments and Middle-Late Stone Age habitat preferences in the Nakuru-Naivasha Basin, Kenya: phytolith-based evidence from the site of Prospect Farm
… xeric savanna, mesic savanna, and forest/wooded habitats, as well as how MSA groups responded to various palaeodemographic pressures. Consequently, these competing models propose contrasting changes in hunter-gatherer mobility and contact/isolation between MSA groups in reaction to the same …

The distribution and habitat preferences of wild ungulates and cattle in Lochinvar National Park, Zambia and the use of resources by people living adjacent to the park
(1) The distribution and habitat preferences of wild ungulates and cattle were determined from observations and counts in Lochinvar National Park and the Game Management Area (GMA) on the west em part of the park on the Kafue river floodplain of Zambia over five months. Oribi, zebra and lechwe were …

Bayesian Hierarchical Methods and the Use of Ecological Thresholds and Changepoints for Habitat Selection Models
Modeling the complex relationships between habitat characteristics and a species' habitat preferences pose many difficult problems for ecological researchers. These problems are complicated further when information is collected over a range of time or space. Additionally, the variety of factors …

Incidence, mechanisms, and consequences of adaptive habitat selection by the dickcissel (Spiza americana)
Most animals display preferences when faced with the choice of habitats in which to settle. A key question that arises from these behaviors is whether preferences represent adaptive habitat selection—do animals occupying preferred habitats incur fitness benefits? A prediction based on natural …

The ecology of the mosquito Culex modestus, a potential vector of West Nile virus in the UK
The aim of this study is to establish the habitat preferences of the mosquito Culex modestus in the UK so that its likely distribution can rapidly be determined in areas most vulnerable to West Nile Virus (WNV) becoming established in the UK. Culex modestus was first found in the North Kent marshes …

Fish Community Assembly in the Forest River, North Dakota, and Resolution of Campostoma Species Presence
… The final aspect of my study was to investigate habitat preferences of fishes in the Forest River. I sampled fish by macrohabitat and compared the results to a similar study. In the determination of the Campostoma species present, I investigated the fishes found in the Red River basin to …

The Distribution and Ecology of Two Kinosternid Turtles in Iowa
… shown that little, if any, shift occurs in the habitat preferences or behavior of Illinois mud turtles and stinkpot turtles in Iowa, at the extreme edge of the species' ranges. The mud turtle is restricted in Iowa to ephemeral ponds associated with Sparta sand or Chelsea loamy fine sand. The …

Wild turkey-road interactions on a Virginia national forest
… by woods or fields less than 80 m wide. Seasonal habitat preferences, rather than vehicular road use levels, seemed to dictate turkey use of the area surrounding Forest Service roads. Revegetated Forest Service roads were preferred habitat in the spring and summer. Turkey mortality was not closely …
