The Paleoproterozoic crust in the north-central U.S. represents intact juvenile terranes accreted to the rifted Archean Superior craton. A new tectonic province map, based on the interpretation of a new aeromagnetic compilation, published geologic maps, and recent geochronologic data, shows progressive accretion of juvenile arc terranes from ca. 1900-1600 Ma....

Growth and sustainability of black bears at White River National Wildlife Refuge, Arkansas
Joseph D. Clark, R. Eastridge
2006, Journal of Wildlife Management (70) 1094-1101
The black bear (Ursus americanus) population at White River National Wildlife Refuge is isolated and genetically distinct, but hunting occurs adjacent to refuge boundaries and females with cubs are removed annually for a reintroduction project. We trapped and radiotracked bears to determine level of exploitation and compare methods for estimating...

C.J. Conway, K.L. Pardieck
2006, Northwest Science (80) 292-297
Anecdotal evidence suggests that burrowing owls have declined in Washington. The Washington Department of Fish and Wildlife is currently conducting a status review for burrowing owls which will help determine whether they should be listed as threatened or endangered in the state. To provide insights into the current...
An efficient method of capturing Painted Buntings and other small granivorous passerines
P.W. Sykes Jr.
2006, North American Bird Bander (31) 110-115
To study survival in the eastern breeding population of the Painted Bunting (Passerina ciris), I developed a technique to capture a large sample of buntings for color marking with leg-bands. This involved the use of bird feeders and an array of three short mist nets located at 40 sites...
The distribution and conservation status of the Gull-billed Tern (Gelochelidon nilotica) in North America
K.C. Molina, R.M. Erwin
2006, Waterbirds (29) 271-295
The Gull-billed Tern (Gelochelidon nilotica) has until recently received little conservation and management attention within North America despite a relatively low overall population size and significant declines in parts of the breeding range. This lack of attention may stem in part from the wide distribution of the species, encompassing...

E. Randolph McFarland, T. Scott Bruce
2006, Professional Paper 1731
A refined descriptive hydrogeologic framework of the Coastal Plain of eastern Virginia provides a new perspective on the regional ground-water system by incorporating recent understanding gained by discovery of the Chesapeake Bay impact crater and determination of other geological relations. The seaward-thickening wedge of extensive, eastward-dipping strata of largely unconsolidated...
