Many amphibians use multiple habitats across seasons. Information on seasonal habitat use, movement between seasonal habitat types, and habitats that may be particularly valuable is important to conservation and management. We used radio-telemetry to study late-season movement and habitat use by Oregon Spotted Frog (Rana pretiosa) at nine sites from...
Efficient delineation of nested depression hierarchy in digital elevation models for hydrological analysis using level-set method
Qiusheng Wu, Charles R. Lane, Lei Wang, Melanie K. Vanderhoof, Jay R. Christensen, Hongxing Liu
2018, Journal of the American Water Resources Association (55) 354-368
In terrain analysis and hydrological modeling, surface depressions (or sinks) in a digital elevation model (DEM) are commonly treated as artifacts and thus filled and removed to create a depressionless DEM. Various algorithms have been developed to identify and fill depressions in DEMs during the past decades. However, few studies...
A spatially discrete, integral projection model and its application to invasive carp
Richard A. Erickson, Eric E. Eager, Patrick Kocovsky, David C. Glover, Jahn L. Kallis, K. R. Long
2018, Ecological Modelling (387) 163-171
Natural resource managers and ecologists often desire an understanding of spatial dynamics such as migration, dispersion, and meta-population dynamics. Network-node models can capture these salient features. Additionally, the state-variable used with many species may be appropriately modeled as a continuous variable (e.g., length) and management activities sometimes can only target individuals of...
Spatial distribution of halogen oxides in the plume of Mount Pagan volcano, Mariana Islands
Christoph Kern, John J. Lyons
2018, Geophysical Research Letters (45) 9588-9596
Halogens are emitted from volcanoes primarily as hydrogen halides (HCl, HF, HBr, and HI). Upon mixing with the atmosphere, chlorine and bromine species are partially converted to the halogen oxides OClO and BrO. Here we report on the spatial distribution of BrO and OClO in the gas plume emitted from...
