Freshwater ecosystems that support juvenile salmonids can be degraded by human pressures such as forestry. Forestry activities can alter water temperatures and the delivery and storage of water, nutrients, wood, and sediment in streams, resulting in changes to the habitat, growth, and survival of juvenile salmon. Previous research on forestry impacts on habitat has focused on small, intensively monitored coastal systems. Here we examined forestry impacts, watershed characteristics, physical habitat, and stream temperature for 28...

This dataset contains the rates of change in juvenile migration timing of 66 Pacific salmon populations ranging from Oregon to Alaska, the rates of change in timing of the initiation of spring phytoplankton bloom in nearby coastal regions, and covariates. Species represented in this dataset include coho salmon (Oncorhynchus kisutch), sockeye salmon (O. nerka), Chinook salmon (O. tshawytscha), pink salmon (O. gorbuscha), chum salmon (O. keta), and steelhead trout (O. mykiss). Rates of change in...

Data were collected to test the theory that marine-derived nutrients can affect insular species richness, population density, and community composition of terrestrial breeding birds. This dataset contains spreadsheets of (1) avian point count surveys, (2) vegetation surveys, (3) cleaned data used in Obrist et al. (2020), and (4) a sub-folder of data used in a community-level analysis by Obrist et al. (2022). This sub-folder contains data required to run a Hierarchical Modelling of Species Communities...

Bumble bees are important pollinators in temperate forested regions where fire is a driving force for habitat change, and thus understanding how these insects respond to fire is critical. Previous work has shown bees are often positively affected by the post-fire environment, with burned sites supporting greater bee abundance and diversity, and increased floral resources. The extent to which fire impacts variation in bumble bee site occupancy is not well understood, especially in higher latitude...

This dataset contains daily counts of juvenile chum salmon (Oncorhynchus keta) from the Skagit River, WA between 1990–2019. The analyzed dataset contains 30 years and 4,636 monitoring days in which 2,358,284 migrating chum salmon were counted. This dataset is the companion dataset for phenomix R package.
