From: Conservation implications of turtle declines in Australia’s Murray River system
Mean catch-per-unit-effort (CPUE; turtles per trap-hour) of (A) Chelodina expansa increased slightly with increasing distance from the Murray River mouth, regardless of wetland type, but this relationship was not retained in reduced models (Table S1). (B) CPUE of C. longicollis increased with increasing distance to the Murray River, and was higher in ponds than in other types of wetlands. The relationship with distance from the Murray River was not retained in a reduced model, but the difference between ponds and other wetlands was (Table S1). (C) CPUE of Emydura macquarii increased with distance from the Murray River mouth and also significantly higher in backwaters, lagoons, lakes and tributaries (BLLT) than in ponds and streams (PS). Lines on each graph represent best-fit regressions identified in log-linear ANCOVAs (Table 1).
