LSD = least significant difference statistic (Conover 1999, p. 371), N = no shell, S =shell, s.d. = standard deviation. The differences in the mean ranks must exceed the LSD value to be considered statistically significant at the 0.05 level. For example, Panzee took 9N significantly earlier in the recovery sequence than 3N, 1N, and all five S bags.
