The cockpit is an environment in which many important tasks simultaneously
compete for pilot attention. Cockpit Task Management (CTM) is the process by
which pilots selectively attend to flight tasks in such a way as to safely and
effectively complete a flight. CTM has been categorized as a mental function...
Quantification and comparison of morphological changes over the last ~300 y in Oregon salt marshes provide valuable insights into the tectonic, hydroclimatic, and anthropogenic processes shaping this important intertidal zone. Understanding of the rates and drivers of salt marsh change contextualizes intertidal habitats within the sediment routing system (i.e., source...
Funk’s (1991) cockpit task management (CTM) theory is structurally consistent with cognitive multitasking models: it addresses managing multiple and concurrent tasks in three stages: situation awareness, response selection, and response execution. Based on CTM theory, Colvin, Funk and Braune (2005) hypothesized that the following six factors may affect task prioritization:...
Understanding the effects of habitat disturbance on a species' habitat selection patterns, and demographic rates, is essential to projecting the trajectories of populations affected by disturbance, as well as for determining the appropriate conservation actions needed to maintain those populations. Greater sage-grouse (Centrocercus urophasianus) is a species of conservation concern...
The stability of 1 3-bis(2-chloroethyl)-1-nitrosourea
(NSC 409962)(BCNU) was investigated in several buffered
aqueous media, in mixed solvent and in nonaqueous solvent
systems, and in the presence of several electrolytes and
nonelectrolytes. The degradation rate constant of BCNU in
these systems was calculated from the parameters of the
linear regression of...
The greater sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) is a ground nesting gallinaceous bird that requires large contiguous patches of sagebrush. Sage-grouse populations have declined, especially in the Great Basin where changes in wildfire regimes and the invasion of annual grasses have contributed to habitat loss and fragmentation. During the last...
Human activities have altered Earth’s ecosystems. Most biomes have experienced a 20-50% conversion to human use. Loss of habitat has obvious effects on the persistence of species. Fragmentation, however, may also negatively affect biodiversity for those species that exhibit behavioral responses to changes in habitat configuration. Such behavioral changes include...
The western United States has experienced large-scale degradation due to land use and land cover changes, invasion of annual grasses, and expansion of woody plants into grass and shrublands and the resultant altered fire regimes. These landscape-scale changes have coincided with declining mule deer (Odocoileus hemionus) populations, making habitat loss...
Thermochemical water splitting cycles have been conceptualized and researched for over half a century, yet to this day none are commercially viable. The heavily studied Sulfur-Iodine cycle has been stalled in the early development stage due to a difficult HI-H₂O separation step and material compatibility issues. In an effort to...
Energy development is expanding rapidly across the western US. Negative effects have been documented for some wildlife, but consequences of development are unclear for other taxa, including raptors. We had the opportunity to examine effects of oil and natural gas development on two raptor species of conservation concern, ferruginous hawks...
