| Summary: | Changing climate is shifting the distributions of marine species, yet the potential for shifts in depth distributions is virtually unexplored. Hydrostatic pressure is proposed to contribute to a physiological bottleneck constraining depth range extension in shallow-water taxa. However, bathymetric limitation by hydrostatic pressure remains undemonstrated, and the mechanism limiting hyperbaric tolerance remains hypothetical. Here, we assess the effects of hydrostatic pressure in the lithodid crab Lithodes maja (bathymetric range 4-790 m depth, approximately equivalent to 0.1 to 7.9 MPa hydrostatic pressure). Heart rate decreased with increasing hydrostatic pressure, and was significantly lower at ≥10.0 MPa than at 0.1 MPa. Oxygen consumption increased with increasing hydrostatic pressure to 12.5 MPa, before decreasing as hydrostatic pressure increased to 20.0 MPa: oxygen consumption was significantly higher at 7.5-17.5 MPa than at 0.1 MPa. Increases in expression of genes associated with neurotransmission, ... : Acute hyperbaric tolerance heart rate and molar oxygen consumption dataAcute hyperbaric tolerance mass-normalised heart rate and mass-normalised mass-specific molar oxygen consumption.Brown&al._J_Exp_Biol_17_acute_hyperbaric_tolerance.xlsxSustained hyperbaric tolerance heart rate and molar oxygen consumption dataSustained hyperbaric tolerance mass-normalised heart rate and mass-normalised mass-specific molar oxygen consumption.Brown&al._J_Exp_Biol_17_sustained_hyperbaric_tolerance.xlsx ... |
