2011, Ecological Applications (21) 2530-2547
The ability to predict amphibian breeding across landscapes is important for informing land management decisions and helping biologists better understand and remediate factors contributing to declines in amphibian populations. We built geospatial models of likely breeding habitats for each of four amphibian species that breed in Yellowstone National Park (YNP)....
Quantifying the influence of sea ice on ocean microseism using observations from the Bering Sea, Alaska
Victor C. Tsai, Daniel E. McNamara
2011, Geophysical Research Letters (38)
Microseism is potentially affected by all processes that alter ocean wave heights. Because strong sea ice prevents large ocean waves from forming, sea ice can therefore significantly affect microseism amplitudes. Here we show that this link between sea ice and microseism is not only a robust one but can be...
Estimating riparian understory vegetation cover with beta regression and copula models
Bianca Eskelson, Lisa Madsen, Joan C. Hagar, Hailemariam Temesgen
2011, Forest Science (57) 212-221
Understory vegetation communities are critical components of forest ecosystems. As a result, the importance of modeling understory vegetation characteristics in forested landscapes has become more apparent. Abundance measures such as shrub cover are bounded between 0 and 1, exhibit heteroscedastic error variance, and are often subject to spatial dependence. These...
