Study Site: Boreal Canada
Purpose: Wetlands and predation in boreal ecosystems play essential roles throughout the breeding season for bird assemblages. We found a positive association of beaver activity and a negative influence of American red squirrels (Tamiasciurus hudsonicus) on bird assemblages. We used a multispecies hierarchical model to investigate whether bird communities differ between two major wetland habitats in boreal Canada: beaver ponds and peatland ponds. In addition to including variables such as forest cover and latitude, we adopted a structural equation model approach to estimate the occupancy of American red squirrels and its potential influence on bird communities.
Abstract: Using automated recording stations deployed at 50 ponds, we detected 96 bird species in 2018 and 2019.
The description of each column header for each spreadsheet is provided in an associated ReadMe file. The steps to follow for each analysis are provided in Supplementary material the R code files. The final dataset included detection/non-detection data for 96 species from 50 ponds from May to August 2018 and 2019 ("Bird_multisp_v2.Rdata"). This dataset is shared in one file in the form of a 3-dimensional array table, which contained rows for pond units (n=100), columns for visits (n=8), and rectangular matrices for species (n=96). Please contact the author for any additional inquiries of how data was collected and analyze.
