Efficacy of eastern encephalitis immunization in whooping cranes

Glenn H. Olsen, M.J. Turell, B.B. Pagac

1997, Journal of Wildlife Diseases (33) 312-315

An epizootic of eastern equine encephalitis (EEE) at the Patuxent Wildlife Research Center (PWRC), Laurel, Maryland (USA), in 1989 provided an opportunity to determine if EEE immunization protected whooping cranes (Grus americana). Based on seroconversion of 31% of sympatric hatch-year sandhill cranes, Grus canadensis,...

L.D. Mech, H.J. Kurtz, S. Goyal

1997, Journal of Wildlife Diseases (33) 321-322

Spatial distribution of larval Ixodes scapularis (Acari:Ixodidae) on Peromyscus leucopus and Microtus pennsylvanicus at two island sites

D. Markowski, K.E. Hyland, H. S. Ginsberg, Renjie Hu

1997, Journal of Parasitology (83) 207-211

Larval blacklegged ticks, Ixodes scapularis, were collected from white-footed mice, Peromyscus leucopus, on Prudence Island (where Microtus pennsylavanicus were not captured) and from meadow voles, M. pennsylvanicus, on Patience Island (where P. leucopus was absent) in Narragansett Bay, Rhode Island from June to October 1992. Ixodes scapularis larvae were also...

Watershield use by ring-necked ducks

J.A. Olsen, Matthew C. Perry

1997, Northeastern Naturalist (4) 197-204

During 1993-94 and 1994-95, the amount of watershield (Brasenia schreberi) in selected Maryland wetlands was determined to see if a relationship existed between the amount of watershield on a wetland and the number of ring-necked ducks (Aythya collaris) observed on that wetland. Data were collected for two years from...

Reproductive biology of the green turtle (Chelonia mydas) at Tern Island, French Frigate Shoals, Hawai`i

K. R. Niethammer, G.H. Balazs, Jeff S. Hatfield, G.L. Nakai, J.L. Megyesi

1997, Pacific Science (51) 36-47

We monitored nesting of the green turtle (Chelonia mydas Linnaeus) on Tern Island, French Frigate Shoals, in the Northwestern Hawaiian Islands from 1986 through 1991. Egg oviposition occurred between 26 April and 20 October. Nesting peaked between mid-June and early August. Hatchlings emerged between mid-August and early...

An adaptive management approach to controlling suburban deer

C.K. Nielson, W.F. Porter, H.B. Underwood

1997, Wildlife Society Bulletin (25) 470-477

Distance sight-resight sampling has particular relevance to aerial surveys, in which height above ground and aircraft speed make the critical assumption of certain detection on the track-line unrealistic. Recent developments in distance sight-resight theory have left practical issues related to data collection as the major impediment to widespread use of...

An example of endurance in an old wolf, Canis lupus

L.D. Mech

1997, Canadian Field-Naturalist (111) 654-655

An 11 to 13-year-old Arctic Wolf (Canis lupus arctos) was observed chasing a young Arctic Hare (Lepus arcticus) for 6 to 7 minutes and catching it. This provides an example of the degree of endurance of which an old wolf is capable....

Migration chronology and distribution of redheads on the lower Laguna Madre, Texas

Christine M. Custer, T. W. Custer, P.J. Zwank

1997, Southwestern Naturalist (42) 40-51

An estimated 80% of redheads (Aythya americana) winter on the Laguna Madre of southern Texas and Mexico. Because there have been profound changes in the Laguna Madre over the past three decades and the area is facing increasing industrial and recreational development, we studied the winter distribution and habitat requirements...

Capture-recapture analysis of a wintering black-capped chickadee population in Connecticut, 1958-1993

G. Loery, James D. Nichols, James E. Hines

1997, The Auk (114) 431-442

We investigated the dynamics of a wintering population of Black-capped Chickadees (Parus atricapillus) using data from a long-term capture-recapture study. Goodness-of-fit and likelihood-ratio tests indicated that the standard Jolly-Seber model was inadequate for the data, so we explored different parameterizations of a model in which survival probability for new captures...

Numerical modeling of late Glacial Laurentide advance of ice across Hudson Strait: Insights into terrestrial and marine geology, mass balance, and calving flux

W.T. Pfeffer, M. Dyurgerov, M. Kaplan, J. Dwyer, C. Sassolas, A. Jennings, B. Raup, W. Manley

1997, Paleoceanography and Paleoclimatology (12) 97-110

A time-dependent finite element model was used to reconstruct the advance of ice from a late Glacial dome on northern Quebec/Labrador across Hudson Strait to Meta Incognita Peninsula (Baffin Island) and subsequently to the 9.9–9.6 ka 14C Gold Cove position on Hall Peninsula. Terrestrial geological and geophysical information from Quebec and...

Biogenic sedimentation beneath the California Current system for the past 30 kyr and its paleoceanographic significance

J.V. Gardner, W.E. Dean, P. Dartnell

1997, Paleoceanography and Paleoclimatology (12) 207-225

A north-south transect of 17 cores was constructed along the eastern boundary of the California Current system from 33° to 42°N to investigate the changes in biogenic sedimentation over the past 30 kyr. Percentages and mass accumulation rates of CaCO3, Corg, and biogenic opal were assembled at 500 to 1000...

Fragmentation and hydration of tektites and microtektites

B.P. Glass, D.W. Muenow, B.F. Bohor, G.P. Meeker

1997, Meteoritics and Planetary Science (32) 333-341

An examination of data collected over the last 30 years indicates that the percent of glass fragments vs. whole splash forms in the Cenozoic microtektite strewn fields increases towards the source crater (or source region). We propose that this is due to thermal stress produced when tektites and larger microtektites fall into...

Spectral characteristics of iron-bearing phyllosilicates: Comparison to Orgueil (CI1), Murchison and Murray (CM2)

W. M. Calvin, T. V. V. King

1997, Meteoritics and Planetary Science (32) 693-701

Phyllosilicate alteration minerals are commonly found in low petrologic types of carbonaceous chondrites. Previous spectral studies have examined Mg-bearing phyllosilicates with limited success in matching the spectral properties of CM and CI chondrites. Transmission electron microscope and other analytical techniques suggest that Fe-bearing clays are more abundant in CI and...

U.S. Geological Survey National Mapping Division

1997, Report

The National Mapping Division (NMD) has developed this comprehensive strategic plan to chart its course over the next decade. To meet the challenge of the future, the NMD is changing its program emphasis, methods of responding to customer need and business practices. The NMD Strategic Plan identifies the new direction...
