FIGURE 4. 40 in New leontiniid Notoungulata (Mammalia) from Chile and Argentina: comparative anatomy, character analysis, and phylogenetic hypotheses
FIGURE 4. 40Ar/39Ar age spectra and inverse isochron plots for samples CH-31 (above) and CH-32 (opposite page). Age spectra illustrate apparent age versus cumulative fraction of 39Ar released. Shaded boxes indicate steps used to calculate weighted mean plateau ages. Plotting these steps suggests that most of them fall on simple isochrons with a 40Ar/36Ar ratio of the trapped component somewhat higher than atmospheric gas, giving a more reliable estimate of the ages at ~19.5 Ma, or ~19.8 Ma when corrected for a revised age of the Fish Canyon Tuff standard.

Fig. 5 in Comparative movement analysis for a sympatric dhole and golden jackal in a human-dominated landscape
Fig. 5. Dhole (column A) and jackal (column B) step length and turning angle distributions of encamped (black) and exploratory (grey) behavioral states. Turning angles (in degrees) for both the encamped and exploratory states are plotted on the same polar plot for each species.
Fig. 4 in Comparative movement analysis for a sympatric dhole and golden jackal in a human-dominated landscape
Fig. 4. Comparison of both species' daily activity patterns. Smoothing was achieved by averaging over 4 hour time intervals. The 95% confidence intervals were estimated from the standard error of the mean step length.

Fig. 6. A in Comparative movement analysis for a sympatric dhole and golden jackal in a human-dominated landscape
Fig. 6. A, Semi-variance comparison of dhole and jackal positions. Since the dhole was monitored for a shorter time than the jackal (due to collar malfunctions), we present comparative data for this shorter time period. B, The complete jackal semi-variogram. Both semi-variograms are limited in scope to the first two thirds of the data, since estimates in the last third of the semi-variogram has very large confidence intervals. Semi-variance and 95% confidence intervals (CI) estimated from the standard error of the mean semivariance, were smoothed using a moving average over 20 lags.
