Fig. 2
Comparison of absolute VCO2 between replete females that fed on either an uninfected calf or a calf infected with B. bovis. A Control ticks had higher overall VCO2 than infected ticks. B Replete females were measured across 3 days. Control ticks had higher VCO2 on days 2 and 3. Linear mixed-effect model results can be found in Table 2. C There were no significant differences between control (gray open triangles) and infected slopes (black closed circles; ANCOVA; F1,111 = 1.32, P = 0.253). However, infected ticks had a significant positive linear relationship with body mass and VCO2 (linear regression; F1,71 = 22.3, P < 0.0001). Significant differences are denoted by * < 0.05, ** < 0.01, and *** P < 0.001. Extending lines represent the 25th to 75th percentiles of the data. Points beyond are considered outliers
