Table 1 Model coefficients for physical factors influencing the selectivity of debris ingestion by sea turtles

From: Mistaken identity? Visual similarities of marine debris to natural prey items of sea turtles

  1. Note that the selectivity ratio indicates the relative strength of the turtles’ selectivity based on each factor. *indicate p values that are significant at the 0.05 level.
  2. aCalculated as the absolute value of the ratio of the size of the turtle effect to the size of the intercept.
