Does choice of estimators influence conclusions from true metabolizable energy feeding trials?
M. H. Sherfy, R. L. Kirkpatrick, K. E. Webb Jr.
2005, Journal of Ornithology (146) 383-389
True metabolizable energy (TME) is a measure of avian dietary quality that accounts for metabolic fecal and endogenous urinary energy losses (EL) of non-dietary origin. The TME is calculated using a bird fed the test diet and an estimate of EL derived from another bird (Paired Bird Correction), the same...
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...
Parasitism, productivity, and population growth: response of Least Bell's Vireos (Vireo bellii pusillus) and Southwestern Willow Flycatchers (Empidonax traillii extimus) to cowbird (Molothrus spp.) control
Barbara E. Kus, Mary J. Whitfield
2005, Ornithological Monographs (57) 16-27
Cowbird (Molothrus spp.) control is a major focus of recovery-oriented management of two endangered riparian bird species,the Least Bell's Vireo (Vireo bellii pusillus) and Southwestern Willow Flycatcher (Empidonax traillii extimus). During the past 20 years, annual trapping of cowbirds at Least Bell's Vireo and Southwestern Willow Flycatcher breeding sites has...

2005, Ecological Applications (15) 2109-2125
Over 75 species of alien plants were recorded during the first five years after fire in southern California shrublands, most of which were European annuals. Both cover and richness of aliens varied between years and plant association. Alien cover was lowest in the first postfire year in all plant associations...
Magma generation at a large, hyperactive silicic volcano (Taupo, New Zealand) revealed by U-Th and U-Pb systematics in zircons
B. L. A. Charlier, C. J. N. Wilson, J. B. Lowenstern, S. Blake, P.W. van Calsteren, J.P. Davidson
2005, Journal of Petrology (46) 3-32
Young (<∼65 ka) explosive silicic volcanism at Taupo volcano, New Zealand, has involved the development and evacuation of several crustal magmatic systems. Up to and including the 26·5 ka 530 km3 Oruanui eruption, magmatic systems were contemporaneous but geographically separated. Subsequently they have been separated in time and have vented from geographically overlapping areas....

Toxic Alexandrium blooms in the western Gulf of Maine: The plume advection hypothesis revisited
D.M. Anderson, B.A. Keafer, W.R. Geyer, R. P. Signell, T.C. Loder
2005, Limnology and Oceanography (50) 328-345
The plume advection hypothesis links blooms of the toxic dinoflagellate Alexandrium fundyense in the western Gulf of Maine (GOM) to a buoyant plume derived from river outflows. This hypothesis was examined with cruise and moored-instrument observations in 1993 when levels of paralytic shellfish poisoning (PSP) toxins were high, and in...

Once abundant and widely distributed, the Bahama parrot (Amazona leucocephala bahamensis) currently inhabits only the Great Abaco and Great lnagua Islands of the Bahamas. In January 2003 and May 2002-2004, we conducted point-transect surveys (a type of distance sampling) to estimate density and population size and make recommendations for monitoring...
Reconstructing a 180 yr record of natural and anthropogenic induced low-oxygen conditions from Louisiana continental shelf sediments
L.E. Osterman, R.Z. Poore, P.W. Swarzenski, R.E. Turner
2005, Geology (33) 329-332
Hypoxia on the Louisiana continental shelf is tied to nutrient Loading and freshwater stratification from the Mississippi River. Variations in the relative abundance of low-oxygen-tolerant benthic foraminifers in four sediment cores from the Louisiana shelf provide a proxy record of low-oxygen events. Core chronologies are obtained using 210Pb dating techniques....
