Turtle relative abundance vs. detectability and road predictors.

Model summaries of the relationship between turtle relative abundance (log[Turtle Detections +1]) and (a) Detectability score and Site Type (Road vs. No Road), (b) Detectability score and Road Density (m/km2), and (c) Detectability score and total traffic volume (Total AADT). Turtle Detections included all turtle sightings and captures that were affected by detectability. The Detectability score was created as the product of pond perimeter and pond visibility (average visible depth). Both road density and total AADT were measured within 300 m of the pond.
