Maximizing the detection probabilities of dusky grouse for population monitoring

Wildlife Biology, EarlyView.
Despite its status as a game species in the western USA, rigorous monitoring of dusky grouse Dendragapus obscurus populations is limited. Obtaining an adequate number of observations for effective population monitoring of dusky grouse is challenging due to difficult‐to‐reach montane habitats, cryptic behaviors, and limited personnel, time, and funds at

Planar laser-induced incandescence for the study of soot production in a multi-sector RQL Jet A combustor

Applications in Energy and Combustion Science
Understanding the production of non-volatile particulate matter (nvPM), which is composed primarily of soot, is critical not only for reducing emissions but also for improving engine performance.

Dusky grouse seasonal resource selection in the Great Basin isolated mountain ranges of Nevada, USA

Wildlife Biology, EarlyView.
Dusky grouse Dendragapus obscurus are a montane forest grouse species with a paucity of information regarding their temporal and spatial resource use during critical times of high mortality and reproductive output. This lack of vital data may leave dusky grouse at risk of sub‐optimal management in many areas of their distribution, especially in the ...

Optical diagnostics of fuel induced soot formation: color ratio pyrometry of in-cylinder soot in a DISI engine

Automotive and Engine Technology
The rapid diversification of gasoline-derived fuels demands a deep understanding of in-cylinder soot formation mechanisms, especially under the transient and low-temperature conditions characteristic of cold-start operation.

Aerothermal modeling program, phase 1 [PDF]

Aerothermal submodels used in analytical combustor models are analyzed. The models described include turbulence and scalar transport, gaseous full combustion, spray evaporation/combustion, soot formation and oxidation, and radiation.

Development of optimized methods for unbiased dusky grouse population monitoring using real and simulated data

Wildlife Biology, EarlyView.
Rigorous state‐wide monitoring programs are lacking for dusky grouse Dendragapus obscurus, a North American species of forest grouse with relatively low detectability that is found in coniferous and mountainous areas in the western United States and Canada.

Assessment of soot formation and thermal radiation in syngas flame using oxygen-enhanced combustion under lean mixing conditions and acetylene doping

International Journal of Thermofluids
Combustion is a predominant global energy source, yet it contributes substantially to environmental degradation through greenhouse gas emissions and particulate matter, including soot.

Abundance and occupancy trends of sooty grouse in western Oregon: determining best modeling practices by comparing observed and simulated data

Wildlife Biology, EarlyView.
Sooty grouse Dendragapus fuliginosus are large game birds that occupy montane forests in the Pacific Northwest, USA. These forests have been altered by human activities, which have been shown to have both positive and negative impacts on local populations.
