BREEDING PRODUCTIVITY, NEST DISTRIBUTION, AND POPULATION ECOLOGY OF WOOD DUCKS IN FLOODPLAIN AND UPLAND FORESTS OF SOUTHERN ILLINOIS
… During 1993-1998, 179 of 244 radiomarked hens remained on the study area as resident hens. One hundred-four nests were located by following radiomarked hens and 66% of nests were found in upland forests. Nests in the floodplain were initiated earlier than nests in the upland. Thirty-six …

Use and Survival of Greater Sage-Grouse in Meadows Managed for Non-Native Ungulate Grazing in Nevada
… a major focus of research. However, low juvenile survival and recruitment has also been implicated as a potential driver in sage-grouse population declines.Nutritional requirements of juvenile sage-grouse combined with the desiccation of key food plants in shrub communities push sage-grouse in the …
