Total short chain fatty acid concentrations in each gut region of four minnow species
| Gut region | C. anomalum | C. oligolepis | C. pauciradii | N. micropogon |
|---|---|---|---|---|
| Proximal | 3.65 ± 0.84 | 6.15 ± 0.75 | 4.55 ± 0.76 | 6.83 ± 0.89 |
| Mid | 4.48 ± 0.51 | 9.39 ± 1.56 | 4.93 ± 1.44 | – |
| Distal | 4.83 ± 0.77 | 7.00 ± 0.82 | 3.91 ± 0.62 | 7.59 ± 1.72 |
| F2,17 = 0.71 | F2,29 = 2.31 | F2,20 = 0.26 | t = 0.39 | |
| P = 0.51 | P = 0.12 | P = 0.77 | P = 0.71 |
Values are mM l−1 intestinal fluid, are presented as mean ± SEM. Comparisons of SCFA concentrations among gut regions for the Campostoma species were made with ANOVA, with differences considered significant at P = 0.05. SCFA concentrations in the PI and DI of N. micropogon were compared with t-test. Sample sizes: C. anomalum (6), C. oligolepis (10), C. pauciradii (7), and N. micropogon (5)
