B. R. Hossack, S. A. Diamond, P.S. Corn
2006, Canadian Journal of Zoology (84) 98-107
A recent increase in ultraviolet B radiation is one hypothesis advanced to explain suspected or documented declines of the boreal toad (Bufo boreas Baird and Girard, 1852) across much of the western USA, where some experiments have shown ambient UV-B can reduce embryo survival. We examined B. boreas occupancy relative...
The effect of multiple stressors on salt marsh end-of-season biomass
J.M. Visser, C.E. Sasser, B.S. Cade
2006, Estuaries and Coasts (29) 331-342
It is becoming more apparent that commonly used statistical methods (e.g. analysis of variance and regression) are not the best methods for estimating limiting relationships or stressor effects. A major challenge of estimating the effects associated with a measured subset of limiting factors is to account for the effects of...

J.T. Rotenberry, K.L. Preston, S. Knick
2006, Ecology (87) 1458-1464
Ecological a??niche modelinga?? using presence-only locality data and large-scale environmental variables provides a powerful tool for identifying and mapping suitable habitat for species over large spatial extents. We describe a niche modeling approach that identifies a minimum (rather than an optimum) set of basic habitat requirements for a species, based...
Risk analysis for biological hazards: What we need to know about invasive species
T.J. Stohlgren, J.L. Schnase
2006, Risk Analysis (26) 163-173
Risk analysis for biological invasions is similar to other types of natural and human hazards. For example, risk analysis for chemical spills requires the evaluation of basic information on where a spill occurs; exposure level and toxicity of the chemical agent; knowledge of the physical processes involved in its rate...

2006, Conference Paper, Recovery of the black-footed ferret: Progress and continuing challenges- Proceedings of the Symposium on the Status of the Black-footed Ferret and Its Habitat, Fort Collins, Colorado, January 28-29, 2004 (Scientific Investigations Report 2005-5293)
We used radio-telemetry data (28,560 positional fixes) collected on 153 black-footed ferrets (Mustela nigripes) to (1) reexamine the assumed obligate relationship of these ferrets to prairie dogs (Cynomys spp.), (2) investigate habitat preferences of ferrets at a small scale (1 year (P = 0.048). Also, preference was stronger for wild-born...
Evaluating habitat for black-footed ferrets: Revision of an existing model
Dean E. Biggins, J. Michael Lockhart, Jerry L. Godbey
2006, Conference Paper, Recovery of the black-footed ferret: Progress and continuing challenges- Proceedings of the Symposium on the Status of the Black-footed Ferret and Its Habitat, Fort Collins, Colorado, January 28-29, 2004 (Scientific Investigations Report 2005-5293)
Black-footed ferrets (Mustela nigripes) are highly dependent on prairie dogs (Cynomys spp.) as prey, and prairie dog colonies are the only known habitats that sustain black-footed ferret populations. An existing model used extensively for evaluating black-footed ferret reintroduction habitat defined complexes by interconnecting colonies with 7-km line segments. Although the...
Monitoring black-footed ferrets during reestablishment of free-ranging populations: Discussion of alternative methods and recommended minimum standards
Dean E. Biggins, Jerry L. Godbey, Marc R. Matchett, Louis R. Hanebury, Travis M. Livieri, Paul E. Marinari
2006, Conference Paper, Recovery of the black-footed ferret: Progress and continuing challenges- Proceedings of the Symposium on the Status of the Black-footed Ferret and Its Habitat, Fort Collins, Colorado, January 28-29, 2004 (Scientific Investigations Report 2005-5293)
Although the monitoring of black-footed ferret (Mustela nigripes) populations following reintroductions has not been haphazard, several ferret recovery groups since 1994 have recommended development of uniform standards prescribing minimum methods, intensities, and frequencies of monitoring that would provide data on population size, mortality rates, and recruitment. Such standards would promote...

2006, Transactions of the American Fisheries Society (135) 129-138
The sablefish Anoplopoma fimbria is a valuable North Pacific Ocean species that, when not targeted in various commercial fisheries, is often a part of discarded bycatch. Predictions of the survival of discarded fish are dependent on understanding how a fish responds to stressful conditions. Our objective was to describe the...
The chlorinated AHR ligand 3,3′,4,4′,5-pentachlorobiphenyl (PCB126) promotes reactive oxygen species (ROS) production during embryonic development in the killifish (Fundulus heteroclitus)
Xabier Arzuaga, Deena Wassenberg, Richard D. Giulio, Adria Elskus
2006, Aquatic Toxicology (76) 13-23
Exposure to dioxin-like chemicals that activate the aryl hydrocarbon receptor (AHR) can result in increased cellular and tissue production of reactive oxygen species (ROS). Little is known of these effects during early fish development. We used the fish model, Fundulus heteroclitus, to determine if the AHR ligand and pro-oxidant 3,3′,4,4′,5-pentachlorobiphenyl (PCB126)...

Relative importance of magnetic moments in UXO clearance applications
V. Sanchez, Y. Li, M. Nabighian, D. Wright
2006, SEG Technical Program Expanded Abstracts (25) 1381-1385
Surface magnetic anomaly observed in UXO clearance is mainly dipolar and, as a result, the dipole is the only moment used regularly in UXO applications. The dipole moment contains intensity of magnetization information but lacks shape information. Unlike dipole, higher-order moments, such as quadrupole and octupole, encode asymmetry properties of...
