For the four linear statistical models of litter loss including the estimated dose rates of organisms types (adj R 2 = 0.33–0.40, F(36, 7) = 4.5–6.0, p<0.002), non-significant terms included moist (t = 1.2–1.3, p>0.21) for all models while size particle fraction > 2mm (log 10 -transformed) was non-significant (t = -1.6, p>0.11) for the two default organism models, nearly significant for the small tube-shape (t = -2.0, p<0.052) and significant for the box shape (t = -2.2, p<0.04).
