Does natural acidity mediate interactions between introduced brown trout, native fish, crayfish and other invertebrates in West Coast New Zealand streams?
2006, Biological ConservationCitation Excerpt :Some crayfish species potentially have negative effects on the distribution of small benthic fishes through predation, competition for food and shelter (Guan and Wiles, 1997; Dorn and Mittelbach, 1999), but in the West Coast streams P. planifrons appeared to have few if any negative effects on the abundance of galaxiids. Tolerance to low pH varies a great deal among crayfish species within the Cambaridae (France, 1993; Seiler and Turner, 2004), whereas species of Astacidae are usually considered to be intolerant of acid water with pH < 5.5 (Nyström, 2002) and low calcium concentrations <2.0 mg/l (Naura and Robinson, 1998). However, in Tasmania Parastacoides tasmanicus and other species of Parastacidae live in highly acidic water (Williams, 1974; Newcombe, 1975).
