Comparison of effects in transcript regulation in gills of Carcinus maenas upon short-term exposure to hypercapnia and low salinity. (A) Regression analysis of gill 9 vs. gill 7 (both days) in the short-term hypercapnia experiment and (B) of gill 7/day 7 (short-term hypercapnia experiment, this study) vs. gill 8/day 7 (salinity dilution experiment by Towle et al. ). The long-dashed black line represents a theoretical regression ratio of 1:1 (equal influence of both factors), while the black line shows the actual regression. Transcripts outside the short-dashed horizontal and vertical lines are more than 2-fold regulated. Please note the different scaling in (A) and (B). Numbers are according to the gene's rank in table 3, indicating transcripts discussed in further detail in the manuscript.
