| Impact Description | A colonization experiment in Yellowstone National Park found a negative relationship between the abundance of New Zealand mudsnail (Potamopyrgus antipodarum) colonizers and native macroinvertebrate colonizers on stone tiles placed in several rivers, suggesting that P. antipodarum may interfere with the colonization activity of native species. However, across sites, significant negative correlations between the densities of P. antipodarum and native macroinvertebrate densities, and overall impacts in this area remain largely unknown. |
