Hydrostatic pressure may present a significant physiological challenge to organisms seeking to colonize deeper waters or migrate ontogenetically. Pressure may be a key factor contributing to bottlenecks in the radiation of taxa and potentially drive speciation.
Here, we assess shifts in the tolerance of hydrostatic pressure through early ontogeny of the northern stone crab Lithodes maja, which occupies a depth range of m in the North Atlantic.
The zoea I, megalopa and crab I stages were exposed to hydrostatic pressures up to This study finds a significant increase in the relative expression of the CS and hsp70a genes with increased hydrostatic pressure in the zoea I stage, and an increase in the relative expression of all genes with increased hydrostatic pressure in the megalopa and crab I stages.
Transcriptional responses are corroborated by patterns in respiratory rates in response to hydrostatic pressure in all stages.
These results suggest a decrease in the acute high-pressure tolerance limit as ontogeny advances, as reflected by a shift in the hydrostatic pressure at which significant differences are observed.

We tested, with high level of success, the generation of ~ ± 49 base-pair sequences in selected groups of decapods hermit crabs, squat lobsters, marine and freshwater crabs and shrimps, encompassing representatives of 27 genera of 15 families, 11 of Pleocyemata Anomura, Brachyura, and Caridea and 4 of Dendrobranchiata.
Based on the results we expect the applicability of these primers for several studies with different taxa within Decapoda.
