Home population estimates
Differences between Partners in Flight roadside sample-based population estimates and spatial model “pixel”-based population estimates align with roadside count and habitat representation differences across 81 species in Northern Alberta, Canada. Red dots indicate species that are well-represented along roads; blue dots indicate species that are under-represented along roads. Filled dots indicate statistically significant differences between population estimates, P < 0.05. (Species codes and values for species represented by unfilled dots can be found in the paper.)
