Nesting and Brood-Rearing Habitat Selection of Greater Sage-Grouse and Associated Survival of Hens and Broods at the Edge of Their Historic Distribution
… declined over the last 60 years due to extensive habitat alteration and loss. Concerns for the management and conservation of greater sage-grouse and their habitats have resulted in petitions to list them under the Endangered Species Act. In North Dakota, sage-grouse are confined to approximately …

Use of Satellite Imagery and GIS to Model Brood-Rearing Habitat for Rio Grande Wild Turkey Populations Occurring in the Western Cross Timbers Region of Texas
… for evaluating spatial components of wildlife habitats. These techniques were implemented to evaluate Rio Grande wild turkey (Meleagris gallopavo) poult-rearing habitat in the Western Cross Timbers region of Texas. Texas Parks and Wildlife (TPWD) random roving turkey counts for 1987-1989 and …

Use and Survival of Greater Sage-Grouse in Meadows Managed for Non-Native Ungulate Grazing in Nevada
… been attributed to extensive loss of sagebrush habitat. Consequently, investigating how disturbance to seasonal sagebrush habitat, such as winter and nesting habitat, affects population dynamics of sage-grouse has been a major focus of research. However, low juvenile survival and recruitment has …

Nesting and Brood Rearing Ecology of the Vancouver Canada Goose on Admiralty Island Southeast of Alaska
<p>Nesting and brood rearing biology of Vancouver Canada geese (Branta canadensis fulva) was studied in 1978 (preliminary) and from April-August 1979 in Seymour Canal, Admiralty Island, Alaska. Geese used trees for perching during the incubation period (24 April-7 June) and use was significant (P < …

Greater Sage-grouse habitat and demographic response to grazing by non-native ungulates
… often focus on the negative impacts to habitat, and speculate how the sage-grouse populations will respond in turn. While the linkage between sage-grouse demographics and habitat is well documented, quantifying the direct impacts of non-native grazing on sage-grouse has been fraught with …

Piping plover breeding biology, foraging ecology and behavior on Assateague Island National Seashore, Maryland
… was higher in bay beach and island interior brood-rearing habitats than on the ocean beach. Our evidence supports the hypothesis that the availability of adequate food is driving the differences in survival observed among brood-rearing habitats. Chicks raised on the bay beach or island …

Wood Duck Brood Movements, Habitat Use, and Survival Rates on Two Prairie Rivers in South Dakota
… their breeding range throughout South Dakota. Brood ecology may differ from traditional breeding areas, and between areas within South Dakota, due to difference in landscape. Wood duck brood movements, habitat use, and survival were studied by radio-marking hens nesting in boxes on the Big …

Waterfowl Pair and Brood Use of Dug brood Complexes in East-Central South Dakota
… employed management technique to enhance habitat for waterfowl and other wetland wildlife. One type of excavation in wetland basins is the dug brood complex; an interconnected system of pond units, channels, and islands, primarily created to provide waterfowl brood rearing habitat during …

Impact of Large Herbivore Use in Meadows on Lentic Function, Wetland Extent and Vegetation Hydric Status
… likely to be high quality sage-grouse late-brood rearing habitat in each of nine allotments. Data collected using a modified draft lentic assessment, inventory, and monitoring protocol informed the interpretation of riparian proper functioning condition (PFC) assessments about management for …

Piping plover habitat suitability on central Long Island, New York barrier islands
… that ephemeral pools were of greater quality for brood-rearing than other ocean beach habitats (intertidal zone, intertidal zone wrack, berm, berm wrack, and open vegetation). Broods with access to ephemeral pools spent more time in them, and when in them had greater foraging rates and were …

Waterfowl Production in the James River Valley of South Dakota
… (acuta). Seventy-two percent of the wetland habitat on the study areas consisted of temporary (Type l and Type 3) water areas. Only 3.9 percent of the wetlands represented semi-permanent (Type 4) and permanent (Type 5) ponds. In 1971, on the Twin lakes Area, only four wetlands held water of …

Availabilty of Potential Invertebrate Foods for Anatini Ducklings Above and Below the Water Surface of Eastern South Dakota Wetlands
… or low-use by dabbler (Anatini) duckling broods according to brood observations. Aquatic and aerial invertebrates were collected from these wetlands using funnel traps and sticky traps, respectively. Aquatic and aerial invertebrates were sorted and identified to family. Total and taxa …
