G. Chander, B. Markham
2003, IEEE Transactions on Geoscience and Remote Sensing (41) 2674-2677
Effective May 5, 2003, Landsat-5 (L5) Thematic Mapper (TM) data processed and distributed by the U.S. Geological Survey (USGS) Earth Resources Observation System (EROS) Data Center (EDC) will be radiometrically calibrated using a new procedure and revised calibration parameters. This change will improve absolute calibration accuracy, consistency over time, and...
Influence of elk grazing on soil properties in Rocky Mountain National Park
Dan Binkley, F. Singer, M. Kaye, R. Rochelle
2003, Forest Ecology and Management (185) 239-247
We used three 35-year exclosures to examine the effects of high elk populations on a variety of soil properties in three vegetation types: upland sagebrush, aspen, and meadow. Grazing and hoof action by elk significantly increased bulk density (from 0.87 kg/l ungrazed to 0.94 kg/l grazed), with greater effects on...
Genetic variation over space and time: Analyses of extinct and remnant lake trout populations in the Upper Great Lakes
B. Guinand, K.T. Scribner, K.S. Page, M. K. Burnham-Curtis
2003, Proceedings of the Royal Society B: Biological Sciences (270) 425-433
Lake trout (Salvelinus namaycush) in the upper Laurentian Great Lakes of North America experienced striking reductions in abundance and distribution during the mid–twentieth century. Complete collapse of populations was documented for Lake Michigan, and a few remnant populations remained only in lakes Huron and Superior. Using DNA obtained from historical...
Evaluation of oral and subcutaneous delivery of an experimental canarypox recombinant canine distemper vaccine in the Siberian polecate (Mustela eversmanni)
Jeffrey Wimsatt, Dean E. Biggins, Kim Innes, Bobbi Taylor, Della Garell
2003, Journal of Zoo and Wildlife Medicine (34) 25-35
We assessed the safety and efficacy of an experimental canarypox-vectored recombinant canine distemper virus (CDV) subunit vaccine in the Siberian polecat (Mustela eversmanni), a close relative of the black-footed ferret, (M. nigripes), an endangered species that is highly susceptible to the virus. Siberian polecats were randomized into six treatment groups....

2003, Conference Paper, Groundwater Quality Modeling and Management Under Uncertinity
Groundwater modeling is a useful tool for evaluating whether an acquifer system is capable of supporting groundwater withdrawals over long periods of time and what effect, if any, such activity will have on the regional flow dynamics as well as on specific public water, agricultural and industrial supplies. An overview...

Historic range of variability in landscape structure in subalpine forests of the Greater Yellowstone Area, USA
D.B. Tinker, W.H. Romme, Don G. Despain
2003, Landscape Ecology (18) 427-439
A measure of the historic range of variability (HRV) in landscape structure is essential for evaluating current landscape patterns of Rocky Mountain coniferous forests that have been subjected to intensive timber harvest. We used a geographic information system (GIS) and FRAGSTATS to calculate key landscape metrics on two ???130,000-ha landscapes...

Moraria hudsoni n. sp. is described from Trails End Bay in Lake Michigan and Prentiss Bay in Lake Huron, Michigan, USA. The new species differs from its congeners in chaetotaxy, body ornamentation, and other characters. We review published records of members of Moraria from North and Central America;...

Unlocking the secrets of Lake Clark sockeye salmon
Carol Ann Woody
2003, Alaska Park Science (2) 33-37
Sockeye salmon are a cornerstone species in many Alaska watersheds. Each summer, adults lay eggs in rocky nests called “redds,” and they die soon after. In spring, their fry emerge from gravels and then rear in a nearby freshwater lake for one year or more before migrating as smolt to...

2003, Arctic Research of the United States (16) 68-73
Dall’s sheep in northwestern Alaska declined in the early 1990s following the severe 1989-90 and 1990-91 winters. In the Baird Mountains of Noatak National Preserve, estimates of adult sheep declined by 50% from 800 in 1989 to under 400 in 1991. Population counts remained low throughout 1991 to 1996, reaching...

2003, Report
In 1995, the Chief Joseph Kokanee Enhancement Project was established to mitigate the loss of anadromous fish due to the construction of Chief Joseph and Grand Coulee dams. The objectives of the Chief Joseph Enhancement Project are to determine the status of resident kokanee (Oncorhynchus nerka) populations above Chief Joseph...

Among the 45 species of bats that occur in the United States (U.S.), 34 species regularly occur in western regions of the country. Many of these “western” species choose roost sites in crevices or cavities. Herein we provide an introduction to the biology of bats that roost in cavities and...
Future coral reef habitat marginality: Temporal and spatial effects of climate change in the Pacific basin
J.M. Guinotte, R. W. Buddemeier, J.A. Kleypas
2003, Conference Paper, Coral Reefs
Marginal reef habitats are regarded as regions where coral reefs and coral communities reflect the effects of steady-state or long-term average environmental limitations. We used classifications based on this concept with predicted time-variant conditions of future climate to develop a scenario for the evolution of future marginality. Model results based...
