Fig. 2. River sections showing movement patterns (black lines) for each of the seven individuals of Diplomystes camposensis studied. a) RT 13, b) RT 14, c) RT 52, d) RT 61, e) RT 62, f) RT 63, g) RT 67. Note that scales are different in each case. Please refer to Fig. 1 for reference to the location of these areas within the main study area (San Pedro River).

Fig. 1 in Movement patterns and home range in Diplomystes camposensis (Siluriformes: Diplomystidae), an endemic and threatened species from Chile

Fig. 1. Study area showing the main course of the San Pedro River, which has its origin in the Riñihue Lake outlet. The confluence with the Quinchilca River is located 40 kilometres downstream, forming the Calle-Calle River. Zoomed area represents kernel home range for individual RT 13. Areas in dark grey, light grey, and white correspond to estimation using 95%, 70% and 50% density, respectively.

Fig. 4 in Movement patterns and home range in Diplomystes camposensis (Siluriformes: Diplomystidae), an endemic and threatened species from Chile

Fig. 4. Relationship between body mass (g) and Kernel home range (m2). Black circles, gray squares, and white pentagons correspond to Kernel estimation with 95%, 75%, and 50% density, respectively.

Fig. 3 in Movement patterns and home range in Diplomystes camposensis (Siluriformes: Diplomystidae), an endemic and threatened species from Chile

Fig. 3. Three measures of movement of Diplomystes camposensis. The x-axis shows six individuals and the combined data during day (D) and night time (N). The y-axis shows values of a) distance from E0 (m); b) Cumulative directional movement (m), and c) Average movement (m), differentiating between displacements upstream (positive) or downstream (negative) in direction. Black squares show mean value and whiskers show standard error. Individual R 52 not included here due to the lack of night measurements.
