This project aims to estimate spatial and temporal trends of waterfowl and waterbirds on the Arctic Coastal Plain (ACP) of Alaska from 2007 to present. The main approach is motivated by Amundson et al. (2019) using space-time generalized additive models (GAMs, Wood, 2017) but with some improvements to handle observer effects and to associate sampling effort to specific spatial locations along a sampled transect similar to Miller et al. (2013). As part of this effort, a major data quality control process was begun in March 2022 that led to the correction of many data errors and re-formatting of the raw 2007 to 2023 data (available at here) to make it more accessible and usable to outside partners. Because of the...

Forests play a role in air quality by supplying the atmosphere with volatile organic compounds (VOCs), precursors to ozone and aerosols. Different tree types emit different VOCs, each with different capacity to form ozone and aerosols. Therefore, shifts in forest composition may impact ozone and aerosol yields. Climate change is one of the expected drivers of forest change. In particular, the current range boundaries of a variety of species are expected to shift northward. The impacts of these climate-induced shifts in forest composition on air quality, particularly VOC emissions and subsequent ozone and aerosol formation, is little understood. This project aimed to explore the relative contribution of shifts in...
