S. DeStefano, C. J. Brand, D. H. Rusch, Daniel L. Finley, Murray M. Gillespie
1991, Wildlife Society Bulletin (19) 23-32
We monitored lead exposure in Eastern Prairie Population Canada geese during summer-winter, 1986-1987 and 1987-1988 at 5 areas. Blood lead concentrations in geese trapped during summer at Cape Churchill Manitoba were below levels indicative of recent lead exposure (0.18 ppm). Geese exposed to lead (≥0.18 ppm blood lead) increased to...

John C. Behrendt, W.E. LeMasurier, A. K. Cooper, Franz Tessensohn, A. Trehu, D. Damaske
1991, Tectonics (10) 1257-1273
The West Antarctic rift system extends over a 3000 × 750 km, largely ice covered area from the Ross Sea to the base of the Antarctic Peninsula, comparable in area to the Basin and Range and the East African rift system. A spectacular rift shoulder scarp along which peaks reach...
Multifragment alleles in DNA fingerprints of the parrot, Amazona ventralis
M.K. Brock, B.N. White
1991, Journal of Heredity (82) 209-212
Human DNA probes that identify variable numbers of tandem repeat loci are being used to generate DNA fingerprints in many animal and plant species. In most species the majority of the sc rable autoradiographic bands of the DNA fingerprint represent alleles from numerous unlinked loci. This study was initiated to...

Glenn D. DelGiudice, L. David Mech, U.S. Seal
1991, Journal of Wildlife Diseases (27) 630-636
We examined weights and hematologic profiles of gray wolf (Canis lupus) pups and the associated wolf density in the east-central Superior National Forest of northeastern Minnesota (USA) during 1970 to 1988. We collected weight and hematologic data from 117 pups (57 females, 60 males) during 1 September to 22 November...

J. F. Carroll, E. Russek-Cohen, J.D. Nichols, J.E. Hines
1991, Environmental Entomology (20) 922-929
We conducted a mark–recapture study in which drag-collected ticks were removed from some park trails weekly from April to July. Weekly survival rates (probability of surviving and remaining on the trails) were significantly lower on trails used heavily by hikers, horses, and pets than on trails used less frequently. Although...

1991, Conservation Biology (5) 41-51
The small group of wolves on Isle Royale has been studied for over three decades as a model of the relationship between large carnivores and their prey. During the last ten years the population declined from 50 individuals to as few as 12 individuals. The causes of this decline may...
Ecology and behavior of the zenaida dove
J. W. Wiley
1991, Ornitologia Neotropical (2) 49-75
Data are summarized from a 10 year study of the Zenaida Dove (Zenaida aurita) in Puerto Rico and its offshore islands. The dove displays sexual size dimorphism, with males generally larger than females: Most activities (feeding, courtship, fighting) occurred in mornings and afternoons, whereas loafing and maintenance activities were more...

J.D. Nichols
1991, Ibis (133) 89-98
Several long-running and geographically extensive survey programmes provide information used to make annual management decisions for North American waterfowl populations. Data from these programmes can also be viewed as resulting from long-term population studies and have formed the basis for a number of retrospective analyses. Short-term studies have been used...

From 1981-1990, 166 (10.1%) of 1636 Roseate Tern (Sterna dougallii) chicks banded from 1978-1985 at Falkner Island, Connecticut, [USA] and 68 (1.0%) of 6904 chicks banded during the same time period at all other colony sites in Connecticut, New York, and Massachusetts, were recaptured as breeding adults at Falkner Island....
Estimates of movement and site fidelity using mark-resight data of wintering Canada geese
J.B. Hestbeck, J.D. Nichols, R.A. Malecki
1991, Ecology (72) 523-533
Population ecologists have devoted disproportionate attention to the estimation and study of birth and death rates and far less effort to rates of movement. Movement and fidelity to wintering areas have important ecological and evolutionary implications for avian populations. Previous inferences about movement among and fidelity to wintering areas have...

K. E. Kunkel, Richard C. Chapman, L.D. Mech, E.M. Gese
1991, Canadian Journal of Zoology (69) 2466-2469
We tested the reliability and predictive capabilities of the activity meter in the new Wildlink Data Acquisition and Recapture System by comparing activity counts with concurrent observations of captive wolf (Canis lupus) and free-ranging white-tailed deer (Odocoileus virginianus) activity. The Wildlink system stores activity data in a computer within...

Bradley S. Van Gosen, Karen J. Wenrich
1991, Open-File Report 91-594-C
Soil sampling surveys were conducted during 1984-1986 across 50 solution-collapse features exposed on the Coconino Plateau of northern Arizona in order to determine whether soil geochemistry can be used to distinguish mineralized breccia pipes from unmineralized collapse features. The 50 sampled features represent the variety of collapse features that crop...
