Smalltooth sawfish (Pristis pectinata) density model fits. Partial effects plots of relative spline fits for the species abundance model (generalized additive model, GAM) predictor terms for smalltooth sawfish, including water temperature (°C), dissolved oxygen (mg/L), salinity, mangrove density (expressed as sum of nearest neighbor scores), year, distance from river mouth (km), if sampling location was in a grid containing exclusively developed shorelines (0: No, 1: Yes). Solid blue lines denote spline fit; dashed blue lines denote 95% confidence bands. Red lines denote reference levels (0).
