In each column, means values (mean ± SD, n = 18) with different letters have a statistically significant difference (P ≤ 0.05), while means having the same letter in the same column are not significantly different (P ≥ 0.05). The capital letters indicate the significance between seasons, and small letters indicate significance between sites
