Crayfish Impact Desert River Ecosystem Function and Litter-Dwelling Invertebrate Communities through Association with Novel Detrital Resources

Figure 2

Effect of virile crayfish presence on breakdown rate (k) of four species of leaf litter.

Crayfish significantly increased breakdown rate of saltcedar (Tukey-Kramer post-hoc test, p<0.01), but did not impact breakdown of seepwillow (Tukey-Kramer post-hoc test, p = 0.59), cottonwood (Tukey-Kramer post-hoc test, p = 1.00), or willow (Tukey-Kramer post-hoc test p = 1.00).
