Table 3: Venous blood analyte values from collected Titmice based on capture location and location relative to Balcones Escarpment.

Mean, standard error, and sample size provided using untransformed values for reference purposes. Probability values from means' significance testing provided with 3 degrees of freedom for capture location and 2 for location relative to Balcones Escarpment. Significant values (α≤0.05) are shown in bold.
