How do papershells compete with these burrowing crayfish in Indiana ponds?
I have not watched for the actual mechanism(s). My guess is that once the Papershell gets its population up with age-2, age-1 and YOY; then they dominate the other Digger and other two species by being more adapted to competitive aquatic setting and having greater size against the YOY Diggers that come in every spring. I am used to finding diggers doing best in ponds that are ephemeral like used by mole salamanders and Spring Peepers. They do not have to compete with other crayfishes there.
