Abstract:
... Removal and distance modeling are two common methods to adjust counts for imperfect detection in point-count surveys. Several recent articles have formulated models to combine them into a distance-removal framework. We observe that these models fall into two groups building from different assumptions about the joint distribution of observed distances and first times to detection. One approach assu ...

Abstract:
... The state of Alaska is experiencing increased coastal erosion due to climatic changes that threaten shoreline, infrastructure, and Alaska Native ways of life. While several Alaska Native villages have been impacted by severe erosion, additional communities face burgeoning erosion concerns. St. Paul, a remote island located in the Bering Sea, Alaska, and home to ~450 Unangan, or Aleut, residents, i ...

In this study we used higher spatial and spectral resolution AVIRIS-NG hyperspectral ...
