@CrawliesWithCri @eatguineapigs Recent work from NPS on invasive signal crayfish and the native Mazama newt in Crater Lake here (https://t.co/K5QVuuttxv); John Umek recently worked on invasive signals in Crater & Lake Tahoe (https://t.co/JsW19JHd4a).

@drkiki And signal crayfish are invasive in Europe, Japan, and in California, where they were stocked places like Lake Tahoe in the late 1800s. They were even introduced to Crater Lake (formerly crayfish-less), where they threaten an endemic newt species:

Here is a case study of an introduced crayfish apparently driving a native amphibian toward local extinction through a combination of antagonistic effects including competition and predation. https://t.co/nTn21Sgm1D https://t.co/UCu5zZVmZ3 https://t.co/Fdc
