Nearshore wave-induced cyclical flexing of sea cliffs
P.N. Adams, C. D. Storlazzi, R. Scott Anderson
2005, Journal of Geophysical Research F: Earth Surface (110)
[1] Evolution of a tectonically active coast is driven by geomorphically destructive energy supplied by ocean waves. Wave energy is episodic and concentrated; sea cliffs are battered by the geomorphic wrecking ball every 4-25 s. We measure the response of sea cliffs to wave assault by sensing the ground motion...

Integrated fire science in the Rocky Mountains
Natasha B. Kotliar
2005, Fact Sheet 2005-3032
Fire is an important ecological process that has helped shape western landscapes. Wildfire suppression and other management practices may have altered historic fire regimes in ecosystems adapted to frequent, low-severity fires. Compounding this problem is the encroachment of homes into fire-prone areas. Fire affects a number of abiotic and biotic components...

S.K. Majumdar, J.E. Huffman, F.J. Brenner, A.I. Panah, editor(s)
2005, Book chapter, Wildlife diseases: Landscape epidemiology, spatial distribution and utilization of remote sensing technology
Few diseases are reported in salamanders. Two notable exceptions are infections by Ranavirus and Ichthyophonus. Except for mortality events associated with ranaviruses in tiger salamanders (Ambystoma tigrinum) and spotted salamanders (A. maculatum), dieoffs of salamanders are rarely detected or reported. Diseases presented in this chapter are those encountered in free-living...

Population genetics of Gunnison sage-grouse: Implications for management
S.J. Oyler-McCance, J. St. John, S.E. Taylor, A.D. Apa, T.W. Quinn
2005, Journal of Wildlife Management (69) 630-637
The newly described Gunnison sage-grouse (Centrocercus minimus) is a species of concern for management because of marked declines in distribution and abundance due to the loss and fragmentation of sagebrush habitat. This has caused remaining populations to be unusually small and isolated. We utilized mitochondrial DNA sequence data and data...
An evaluation of weather and disease as causes of decline in two populations of boreal toads
Rick D. Scherer, Erin L. Muths, Barry R. Noon, Paul Stephen Corn
2005, Ecological Applications (15) 2150-2160
Two populations of boreal toads (Bufo boreas) experienced drastic declines in abundance in the late 1990s. Evidence supported the hypothesis of disease (the chytrid fungus, Batrachochytrium dendrobatidis) as the cause of these declines, but other hypotheses had not been evaluated. We used an 11-year capture–recapture data set to...
Effectiveness of methyl bromide as a cargo fumigant for brown treesnakes
P.J. Savarie, W.S. Wood, G.H. Rodda, R. L. Bruggers, R.M. Engeman
2005, International Biodeterioration and Biodegradation (56) 40-44
The effectiveness of methyl bromide as a fumigant for brown treesnake (Boiga irregularis) management was evaluated on Guam. Eighteen snakes in secured cloth bags were randomly positioned in a 47.7-m3 tarpaulin-covered cargo container for each fumigation treatment. Methyl bromide treatments tested were: 24 g m−3 and and 12 g m−3, both for 2-h and...
A multilocus population genetic survey of greater sage-grouse across their range
Sara J. Oyler-McCance, S.E. Taylor, T.W. Quinn
2005, Molecular Ecology (14) 1293-1310
The distribution and abundance of the greater sage-grouse (Centrocercus urophasianus) have declined dramatically, and as a result the species has become the focus of conservation efforts. We conducted a range-wide genetic survey of the species which included 46 populations and over 1000 individuals using both mitochondrial...

Gulf of Mexico Integrated Science - Tampa Bay Study: Examining the Impact of Urbanization on Seafloor Habitats
Kimberly Yates
2005, Open-File Report 2005-1017
Seafloor habitats, such as seagrass beds, provide essential habitat for fish and marine mammals. For many years, the study of seagrass vitality has been a priority for scientists and resource managers working in Tampa Bay. Seafloor habitats are extremely sensitive to changes in water quality. Like a canary in a...
Tree species and size structure of old-growth Douglas-fir forests in central western Oregon, USA
Nathan Poage, J. C. Tappeiner II
2005, Forest Ecology and Management (204) 329-343
We characterized the structure of 91 old-growth forests dominated by Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), using inventory data from recent (1985–1991) old-growth timber sales in western Oregon. The data were complete counts (i.e., censuses) of all live trees >20 cm diameter at breast height (dbh, measured at 1.4 m above the ground) over...

Parental nest defense on videotape: More reality than "myth"
Pamela J. Pietz, Diane A. Granfors
2005, The Auk (122) 701-705
Predation is recognized as the primary source of nest mortality in most passerine species (e.g. Ricklefs 1969, Martin 1992a); thus, it is no surprise that parental nest defense has received considerable scientific attention (see below). By nest defense, we refer to any parental behavior that decreases the probability that a...
