Figure 5: Linear model of the relationship between the percent change in
occupancy of shorebird species from 1994-97 to 2019 and their Species
Temperature Index. Intercept = -95.49, Slope = 55.72, p = 0.01, Adjusted
R² = 0.51. The Species Temperature Index is the mean June Temperature
from 1970 to 2000 across the species range. See Table 2 for a legend of
4-letter bird species codes

Table 1: Generalized linear model results for change in occupancy,
richness and density of breeding shorebirds (all species) from 1994-97
to 2019 in Foxe the Rasmussen Lowlands and Foxe Basin (n = 64). The
models included time period as the main predictor of interest, region to
control for any regional effects, and habitat to control for any habitat
effects (of upland and lowland habitat). The occupancy model used a
binomial distribution, and the species richness and density models used
negative binomial distributions. The intercept represents the parameter
estimate for reference categories (1994-97, Foxe Basin, lowland). The
estimate for the parameters in brackets (2019, Rasmussen, upland)
represent the difference for that category and the reference level.
