Nesting ecology and behavior of Broad-winged Hawks in moist karst forests of Puerto Rico
D.W. Hengstenberg, F. J. Vilella
2005, Journal of Raptor Research (39) 404-416
The Puerto Rican Broad-winged Hawk (Buteo platypterus brunnescens) is an endemic and endangered subspecies inhabiting upland montane forests of Puerto Rico. The reproductive ecology, behavior, and nesting habitat of the Broad-winged Hawk were studied in Ri??o Abajo Forest, Puerto Rico, from 2001-02. We observed 158 courtship displays by Broad-winged Hawks....
Material contrast does not predict earthquake rupture propagation direction
R.A. Harris, S.M. Day
2005, Geophysical Research Letters (32) 1-4
Earthquakes often occur on faults that juxtapose different rocks. The result is rupture behavior that differs from that of an earthquake occurring on a fault in a homogeneous material. Previous 2D numerical simulations have studied simple cases of earthquake rupture propagation where there is a material contrast across a fault...
Resource inventory of marine and estuarine fishes of the West Coast and Alaska: A checklist of North Pacific and Arctic Ocean species from Baja California to the Alaska - Yukon border
Milton S. Love, Catherine W. Mecklenburg, T. Anthony Mecklenburg, Lyman K. Thorsteinson
2005, Report
This is a comprehensive inventory of the fish species recorded in marine and estuarine waters between the Alaska–Yukon Territory border in the Beaufort Sea and Cabo San Lucas at the southern end of Baja California and out about 300 miles from shore. Our westernmost range includes the eastern Bering Sea...
Seabird, fish, marine mammal, and oceanography coordinated investigations (SMMOCI) in Sitka Sound, Alaska, July 2000
John F. Piatt, Donald E. Dragoo
2005, U.S. Fish and Wildlife Service Report AMNWR 04/01
Surveys for seabirds and marine mammals were conducted in and near Sitka Sound, Alaska (Fig. 1) from the M/V Tiĝlax̂ during 12-16 July 2000 (Table 1, Fig. 1). The objective was to characterize the marine environment in the vicinity of St. Lazaria Island, one of ten seabird colonies monitored annually...
Survey of wildlife rehabilitators on infection control and personal protective behaviors
Emi Saito, Allison R. Shreve
2005, Wildlife Rehabilitation Bulletin (23) 42-46
Wildlife veterinarians and rehabilitators treat a number of wildlife species that can carry infectious and zoonotic diseases. These can rapidly spread within a facility and to the caregivers when adequate measures are not taken. Financial constraints and reduced access to laboratories often limit identification of disease etiology of many cases...
Status of amphibians on the Continental Divide:Surveys on a transect from Montana to Colorado, USA
P.S. Corn, B. R. Hossack, E. Muths, D.A. Patla, C.R. Peterson, Alisa L. Gallant
2005, Alytes (22) 85-94
The Rocky Mountain Region of the United States Geological Survey's Amphibian Research and Monitoring Initiative is conducting monitoring of the status of amphibians on a transect that extends along the Continental Divide from Canada to Colorado and comprises four National Parks. Monitoring uses visual encounter surveys to determine site occupancy,...
Effects of conifers and elk browsing on quaking aspen forests in the central Rocky Mountains, USA
Margot W. Kaye, Dan Binkley, Thomas J. Stohlgren
2005, Ecological Applications (15) 1284-1295
Elk browsing and conifer species mixing with aspen (Populus tremuloides Michx.) present current challenges to aspen forest management in the western United States. We evaluated the effects of conifers and elk browsing on quaking aspen stands in and near Rocky Mountain National Park using tree rings to reconstruct patterns...
Variation in torpor patterns of free-ranging black-tailed and Utah prairie dogs across gradients of elevation
E.M. Lehmer, E. Biggins
2005, Journal of Mammalogy (86) 15-21
We compared over-winter body temperature (Tb) patterns for more than 6 months in adult (> 1 year) black-tailed (Cynomys ludovicianus) and Utah (C. parvidens) prairie dogs from colonies located along gradients of elevation in northern Colorado and southern Utah. In general, black-tailed prairie dogs entered torpor facultatively during winter, whereas...
Lichens of the U.S. National Parks
J. P. Bennett, C. M. Wetmore
2005, Bryologist (108) 544-553
Over 26,100 records of lichens present in 144 U.S. national park units were assembled from various sources into a database and analyzed. Within these 144 park units 2,435 species and 375 genera are reported, representing 63% and 74% of the North American flora, respectively. The park units are located in...
Rural land-use trends in the conterminous United States, 1950-2000
Daniel G. Brown, Kenneth M. Johnson, Thomas R. Loveland, David M. Theobald
2005, Ecological Applications (15) 1851-1863
In order to understand the magnitude, direction, and geographic distribution of land-use changes, we evaluated land-use trends in U.S. counties during the latter half of the 20th century. Our paper synthesizes the dominant spatial and temporal trends in population, agriculture, and urbanized land uses, using a variety of data sources...
Soil biota can change after exotic plant invasion: Does this affect ecosystem processes?
Jayne Belnap, Susan L. Phillips, S. K. Sherrod, A. Moldenke
2005, Ecology (86) 3007-3017
Invasion of the exotic annual grass Bromus tectorum into stands of the native perennial grass Hilaria jamesii significantly reduced the abundance of soil biota, especially microarthropods and nematodes. Effects of invasion on active and total bacterial and fungal biomass were variable, although populations generally increased after 50+ years of invasion....
