Oxygen consumption in hatching juvenile <i>Buccinum undatum</i> from the Solent (UK) and Breiðafjörður (Iceland).

<p>(a) Effects of temperature on oxygen consumption. Data for each temperature is averaged from 5 pressures (1, 100, 200, 300, 400 atm). Closed circles, Breiðafjörður data; open circles, Solent data. General Linear Model ANOVA indicated oxygen consumption to be significantly affected by temperature (<i>p≤</i>0.001); different letters indicate values that are significantly different. For each data point n = 45. (b) Effects of hydrostatic pressure on oxygen consumption. Data for each pressure is averaged across temperatures (6, 10, 14, 18°C for Solent samples; 3, 6°C for Breiðafjörður samples). Closed circles, Breiðafjörður data; open circles, Solent data. Oxygen consumption was significantly affected by pressure (<i>p≤</i>0.001); different letters indicate values that are significantly different. For each data point n = 54. (c) Change in oxygen consumption with pressure, at 6 temperatures. Closed circles, 3°C Breiðafjörður; open circles, 6°C Breiðafjörður; closed triangles, 6°C Solent; open triangles, 10°C Solent; closed squares, 14°C Solent; open squares, 18°C Solent. Oxygen consumption was significantly affected by temperature - pressure interactions (<i>p≤</i>0.001); see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0051219#pone-0051219-t002" target="_blank">table 2</a> for <i>post hoc</i> analysis (Sidak simultaneous test). For each data point, n = 9. Data were analysed using General Linear Model ANOVA. Error bars display standard error.
