Subduction cycles under western North America during the Mesozoic and Cenozoic eras
Peter L. Ward
David M. Miller, Cathy Busby, editor(s)
1995, Book chapter, Jurassic magmatism and tectonics of the North American cordillera
An extensive review of geologic and tectonic features of western North America suggests that the interaction of oceanic plates with the continent follows a broad cyclical pattern. In a typical cycle, periods of rapid subduction (7–15 cm/yr), andesitic volcanism, and trench-normal contraction are followed by a shift to trench-normal extension,...

1995, Book chapter, Our living resources: A report to the nation on the distribution, abundance, and health of U.S. plants, animals, and ecosystems
The North American group of shorebirds includes 48 kinds of sandpipers, plovers, and their allies, many of which live for most of the year in coastal marine habitats; other live principally in nonmarine habitats including grasslands, freshwater wetlands, and even second-growth woodlands. Most North American shorebirds are highly migratory, while...

1995, Book chapter, Our living resources: A report to the nation on the distribution, abundance, and health of U.S. plants, animals, and ecosystems
Large changes have occurred in the geographic wintering distribution and subspecies composition of the Atlantic Flyway population of Canada geese (Branta canadensis) over the last 40 years. The Atlantic Flyway can be thought of as being partitioned into four regions: South, Chesapeake, mid-Atlantic, and New England. Wintering numbers have declined...

1995, Book chapter, Our living resources: A report to the nation on the distribution, abundance, and health of U.S. plants, animals, and ecosystems
Increased predation and habitat degradation and destruction coupled with drought, especially on breeding grounds, have caused the declines of some duck populations. More than 30 species of fucks breed in North America, in areas as diverse as the Arctic tundra and the subtropics of Florida and Mexico. For many of...
Seabirds in Alaska

1995, Book chapter, Our living resources: A report to the nation on the distribution, abundance, and health of U.S. plants, animals, and ecosystems
About 100 million seabirds reside in marine waters of Alaska during some part of the year. Perhaps half this population is composed of 50 species of nonbreeding residents, visitors, and breeding species that use marine habitats only seasonally (Gould et al. 1982). Another 30 species include 40-60 million individuals that...

Arctic nesting geese: Alaskan populations

1995, Book chapter, Our living resources: A report to the nation on the distribution, abundance, and health of U.S. plants, animals, and ecosystems
North American populations of most goose species have remained stable or have increased in recent decades (USFWS and Canadian Wildlife Service 1986). Some populations, however, have declined or historically have had small numbers of individuals, and thus are of special concern. Individual populations of geese should be maintained to ensure...
A ten-year history of the demography and productivity of an Arctic wolf pack
L.D. Mech
1995, Arctic (48) 329-332
A pack of two to eight adult wolves (Canis lupus arctos) and their pups was observed during ten summers (1986-95) on Ellesmere Island, Northwest Territories, Canada. The author habituated the wolf pack to his presence in the first summer and reinforced the habituation each summer thereafter. The first alpha female...
Demography of birds in a neotropical forest: Effects of allometry, taxonomy, and ecology
J. D. Brawn, James R. Karr, James D. Nichols
1995, Ecology (76) 41-51
Comparative demographic studies of terrestrial vertebrates have included few samples of species from tropical forests. We analyzed 9 yr of mark—recapture data and estimated demographic parameters for 25 species of birds inhabiting lowland forests in central Panama. These species were all songbirds (Order Passeriformes) ranging in mass from 7 to...
Canada geese in North America

Canada geese (Branta canadensis) are probably more abundant now than at any time in history. They rank first among wildlife watchers and second among harvests of waterfowl species in North America. Canada geese are also the most widely distributed and phenotypically (visible characteristics of the birds) variable species of bird...
Biology and status of the shortnose cisco Coregonus reighardi Koelz in the Laurentian Great Lakes
Shane A. Webb, Thomas N. Todd
1995, Book chapter, Archiv fur Hydrobiologie; Biology and Management of Coregonid Fishes -- 1993
The shortnose cisco, Coregonus reighardi, a member of the endemic species assemblage of Coregoninae in the Laurentian Great Lakes, was commercially important until overfishing and competition pressures from induced planktivores extirpated the species in Lakes Michigan and Ontario. Spawning shortnose ciscoes have been collected from Lake Huron and Georgian Bay...
Geology, hydrology, and mechanics of a slow-moving, clay-rich landslide, Honolulu, Hawaii
Rex L. Baum, Mark E. Reid
William C. Haneberg, Scott A. Anderson, editor(s)
1995, Book chapter, Clay and shale slope instability
The Alani-Paty landslide has damaged streets, utilities, and homes built on a debris apron in Honolulu, Oahu, Hawaii. Failure of weathered, crudely stratified, highly plastic, debris-apron deposits has created several similar landslides in southeastern Oahu. The Alani-Paty landslide affects about 60 residential lots. It is about 300 m long, 160...
Planning long-term vegetation studies at landscape scales
Thomas J. Stohlgren
1995, Book chapter, Ecological Time Series
Long-term ecological research is receiving more attention now than ever before. Two recent books, Long-term Studies in Ecology: Approaches and Alternatives, edited by Gene Likens (1989), and Long-term Ecological Research: An International Perspective, edited by Paul Risser (1991), prompt the question, “Why are these books so thin?” Except for data...
Chronology and dynamics of a large silicic magmatic system: Central Taupo Volcanic Zone, New Zealand
B. F. Houghton, C. J. N. Wilson, M.O. McWilliams, Marvin A. Lanphere, S.D. Weaver, R. M. Briggs, M. S. Pringle
1995, Geology (23) 13-16
The central Taupo Volcanic Zone in New Zealand is a region of intense Quaternary silicic volcanism accompanying rapid extension of continental crust. At least 34 caldera-forming ignimbrite eruptions have produced a complex sequence of relatively short-lived, nested, and/or overlapping volcanic centers over 1.6 m.y. Silicic volcanism at Taupo is similar...

As part of continuing research aimed at the detection of subsurface tunnels and voids, the U.S. Bureau of Mines recently completed a cooperative study with the U.S. Geological Survey at a surface gold mine in the Black Hills mining district of South Dakota. The occurrence of older, poorly mapped mine workings in...

1995, Book chapter, Our living resources: A report to the nation on the distribution, abundance, and health of U.S. plants, animals, and ecosystems
Populations of many North American land-birds, including forest-inhabiting species that winter in the Neotropics, seem to be declining (Robbins et al. 1989; Terborgh 1989). These declines have been identified through broad-scale, long-term survey programs that identify changes in abundance pf species, but provide little information about causes of changes in...
Trichomoniasis as a factor in mourning dove population decline in Fillmore, Utah
William D. Ostrand, John A. Bissonette, M. R. Conover
1995, Journal of Wildlife Diseases (31) 87-89
We examined whether trichomoniasis had been a factor in a dramatic mourning dove (Zenaida macroura) population decline in Fillmore, Utah (USA). We reasoned that if we could not find a high proportion of doves showing clinical signs of disease then the population was not being affected. Prevalences of Trichomonas...
