Average rate of population biomass increase (in day ⁻¹) in different competition and salinity scenarios.

<p>Panels represent three competition scenarios, which differ in the order of inoculation of the species (see text for codes). Competitor species are shown as black (<i>Daphnia galeata</i>) and white (<i>Simocephalus vetulus</i>) bars. Error bars represent 95% confidence intervals of the mean (n = 3 experimental microcosms). Mean parwise ratios (and 95% confidence interval) of the biomass increase of competing species (<i>Daphnia:Simocephalus</i>) are shown, along with associated significance (adjusted for multiple comparisons, by controlling false discovery rate) for one-sample <i>t</i>-tests. Ratios that are significantly different from 1 are highlighted in bold: ratios significantly higher than 1 stand for higher biomass increase rate of <i>Daphnia</i> relatively to <i>Simocephalus</i>, whilst ratios <1 stand for the contrary scenario.
