Data from: Nonconsumptive predator effects modify crayfish-induced bioturbation as mediated by limb loss: field and mesocosm experiments

1. We addressed the implications of limb loss and regeneration for
multi-species interactions and their impacts on ecosystem engineering in
freshwater stream environments. 2. We included regenerative and
non-regenerative crayfish as well as fish predators in a 2x2 factorial
design to assess the effects on water turbidity of interactions between
crayfish ecosystem engineers differing in regenerative status and their
fish predators. 3. We demonstrated that crayfish limb loss and predation
risks lead to more turbidity in field and mesocosm conditions. Moreover,
ongoing regeneration of crayfish increased turbidity, while fish presence
seemed to hinder crayfish turbidity-inducing behaviors (such as
tail-flipping and burrowing) in the mesocosm experiment. 4. We confirmed
that greater numbers of crayfish produce a greater amount of turbidity
in-situ in streams. 5. Although mechanical burrowing crayfish capacities
may depend on crayfish burrowing classification (primary, secondary, or
tertiary), our work emphasizes the implication for turbidity levels of
crayfish autotomy in freshwater streams.
