I'm currently doing my master thesis in Ecology and now writing my result section. I'm a non-native English writer and I would like to ask for some help structuring my sentences and how to become a better writer. The sample I provide is of my results. I would like to improve the 'flow' of my writing, now I feel I'm just writing one and one sentence independently of the latter, giving a terrible 'flow'. Here I'm describing the results from a boxplot:
In the treatments with reference water (pH 7.0) and acidic Al-poor media (pH 5.8) A. aquaticus showed a median normoxic O2-consumption of 0.023 and 0.028, the IQR was 0.029 and 0.045 µgO2/mg DW-1 ·h-1, respectively. Whereas for the acidic Al-rich media (pH 5.8) the median normoxic O2-consumption was lower at 0.006 and the IQR was 0.003 µgO2/mg DW-1 ·h-1 (Figure X4). The median critical O2 concentration ([O2]crit (mg O2/L-1) for A. aquaticus was 1.56 and 1.35, with an IQR of 0.50 and 0.52 [O2]crit (mg O2/L-1), when exposed to reference water (pH 7.0) and acidic Al-poor media (pH 5.8), respectively. For animals exposed to the treatment acidic Al-rich media (pH 5.8) the median critical O2 concentration was 0.90 and the IQR 0.54 [O2]crit (mg O2/L-1).
Another sample of my writing:
Water pH was very stable in the mortality and respirometry experiments, with only minor fluctuations (Table X3). For the mortality experiment the reference water varied by ±0.11SD from its mean pH 7.03. While variations for the acidic Al-poor and acidic Al-rich were ±0.48SD and ±0.38SD from their mean of pH 5.73 and 5.72, respectively. For the respirometry experiment, the reference water varied with ±0.18SD from its mean pH 7.04. And the acidic Al-poor and the acidic Al-rich varied with ±0.59SD and ±0.17SD from their mean of pH 5.94 and pH 5.95, respectively. The same applies here for the variation in the acidic Al-poor treatment, malfunctioning of the ball valve mentioned above.
