Factors Influencing Predation on Ruffed Grouse in the Appalachians
Predation accounts for the majority of ruffed grouse mortality beyond the brooding period throughout grouse range. Most studies of ruffed grouse ecology have taken place in the central portion of the species range including the Great Lakes states and southern Canada where aspen (Populus …

Regional variation in the nutritional ecology of ruffed grouse
Three experiments with captive ruffed grouse (Bonasa umbellus) demonstrated that dietary metabolizable energy (ME) can be predicted from neutral detergent solubles, total phenols, and percent acorns of grouse diets. The weight of the fat attached to the gizzard was highly correlated with percent …

Ruffed grouse nutrition and foraging in the southern Appalachians
Feeding trials.showed that ruffed grouse (Bonasa umbellus) performed well on diets containing 20% Christmas hollyfem (Polystichum acrostichoides) or mountain laurel (Kalmia latifolia), but diets containing 40% of these forages resulted in lower protein and energy intake and the Christmas hollyfem …

Selection of landscapes by male ruffed grouse during peak abundance.
Most research on ruffed grouse (Bonasa umbellus) habitat selection has focused either on habitat structure within their activity centers or characteristics of forest stands containing activity centers. I studied the relationship between landscape configuration and density of male grouse during the …

Factors influencing ruffed grouse productivity and chick survival in West Virginia
… chick mortality, and factors influencing ruffed grouse (Bonasa umbellus) chick survival in West Virginia during 1998--1999. The proportion of hens that attempted to nest, hen success, average clutch size, and hatch dates were similar between age classes, between sites, and between years. …

Ruffed grouse (Bonasa umbellus) habitat ecology in the central and southern Appalachians
Ruffed grouse populations are low in Appalachian forests, possibly because low habitat quality negatively affects survival, condition, and reproduction. Through the Appalachian Cooperative Grouse Research Project (ACGRP) researchers tracked >1500 radioed grouse at 10 study sites (1996__2002). To …

Population ecology of and the effects of hunting on ruffed grouse (Bonasa umbellus) in the southern and central Appalachians
I investigated ruffed grouse (Bonasa umbellus) population ecology in the southern and central Appalachians as part of the Appalachian Cooperative Grouse Research Project (ACGRP). Several hypotheses have been offered to explain the low abundance of ruffed grouse in the region including inadequate …

Ruffed grouse natality, chick survival, and brood micro-habitat selection in the southern Appalachians
… study conducted by the Appalachian Cooperative Grouse Research Project (ACGRP). Nesting rate, pooled over all regions, was 83.6% in 1997 and 79.7% in 1998. In the 2-year period, the Alleghany Plateau reported the highest nesting rate (97.6%) while the Ohio River Valley reported the lowest rate …

Multiscale Resource Selection of Ruffed Grouse in the Black Hills National Forest of South Dakota and Wyoming
Ruffed grouse (Bonasa umbellus) are popular upland game birds as well as the management indicator species (MIS) for aspen (Populus tremuloides) in the Black Hills National Forest (BHNF). Due to this status the U.S. Forest Service and the South Dakota Department of Game Fish and Parks had interest …

Relationship of Ruffed Grouse Home Range Size and Movement to Landscape Characteristics in Southwestern Virginia
… the effects of landscape characteristics on ruffed grouse (Bonasa umbellus) home range size and movement, and examined grouse selection for specific landscape characteristics and cover types. Grouse home ranges and movement patterns derived from telemetry data gathered from fall 1996 through …

The wired wilderness : electronic surveillance and environmental values in wildlife biology
… situated relationships with game animals such as ruffed grouse, which they hoped would bolster their authority vis-a-vis recreational hunters. I then show how the technique was contested by environmentalists when biologists applied it to iconic "wilderness wildlife" such as grizzly bears in …
