| Impact Description | Potamopyrgus antipodarum limited the growth of Pyrgulopsis robusta and became dominant in many habitats. Interestingly, analysis indicated that both species consumed similar amounts of algal resources, discrediting resource acquisition ability as a mechanism for interspecific competition. The authors suggest that adverse impacts on P. robusta could stem from lower maintenance costs or more efficient resource conversion within P. antipodarum. |
