Working With Land Managers To Identify And Manage Potential Stopover Locations For Whooping Cranes, Chester A. Mcconnell
Working With Land Managers To Identify And Manage Potential Stopover Locations For Whooping Cranes, Chester A. Mcconnell
Proceedings of the North American Crane Workshop
Whooping cranes (Grus americana) of the Aransas-Wood Buffalo Population migrate 4,000 km twice each year between their nesting grounds in northern Canada and their wintering grounds on the Texas Gulf Coast. During migration, whooping cranes must land at suitable ponds or wetlands to feed or rest. The Whooping Crane Recovery Plan calls for the protection and management of whooping crane stopover locations within the migration corridor. While major stopover areas have been protected, many other smaller sites remain to be identified. Moreover, the Recovery Plan offers no specific entity to protect and manage the latter. To address these …

Conclusions
It is our contention that Thomas Say, Titian Peale, Edwin James, and their colleagues of the Stephen Long Expedition of 1819–1820 were heavily engaged in scientific research, which took the form of the first biodiversity inventory undertaken in the United States. This accomplishment has been overlooked both by biologists and historians, but it should rank among the most significant accomplishments of the expedition. The results of this inventory continue to inform us today about environmental, faunal, and floral changes along the Missouri River in an area that is known to be an ecotone between the deciduous forests of the …

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
As concern about declining pollinator populations mounts, it is important to understand the range of insect taxa that provide pollination services. We use pollen transport information acquired over three years in two habitats at Badlands National Park, South Dakota, USA, to compare probabilities of pollen transport among insect taxa and between sexes of bees. Sampling was conducted on 1-ha plots, eight in sparse vegetation (May–October samples; N = 74 surveys) and 12 in wheatgrass prairie vegetation (June–July samples; N = 87 surveys). Insects contacting reproductive parts of flowers were netted, placed individually into tubes charged with ethyl acetate, then transferred …
