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...

BIOLOGICAL CLASSIFICATION,
Located between Wellfleet and Turo, Massachusetts, the 1100-acre Herring River watershed has historically provided many ecological and social benefits, including forest and wetland habitat for native fish, birds, and mammals and recreational and educational opportunities for residents and visitors. Construction of a dike and ditches beginning in the early 1900s constricted tidal exchange into the river basin, resulting in ecological degradation of the estuary, loss of valued salt marsh and extensive conversion to upland habitat vegetation. Tidal restrictions limit passage of fish species that spend their time in both fresh and salt water into the Herring River, have resulted in dangerous bacterial levels posing...
