“…Palaemonetes varians specimens subjected to the CT max determination experiments were acclimated at 10°C and brought to 31°C in less than 1h; those subjected to pressurisation experiments were progressively acclimated to 30°C for 3days. As both acclimation temperature and thermal ramping rate are known to affect CT max (Rodríguez and Ramirez, 1997;Herrera et al, 1998;Díaz et al, 2002;Chown et al, 2009), this could explain the apparent difference in thermal tolerance between these two batches of shrimp.…”

2002). The potential for depth range extension and colonisation of the deep sea may, therefore, be genuine for some shallow-water species. There is evidence that the echinoid Echinus acutus has extended its bathymetric range, indicating that migrations to the deep sea are still occurring (Tyler and Young, 1998 Accepted 8 December 2010 SUMMARY To date, no published study has assessed the full physiological scope of a marine invertebrate species with respect to both temperature and hydrostatic pressure. In this study, adult specimens of the shallow-water shrimp species Palaemonetes varians were subjected to a temperature/pressure regime from 5 to 30°C and from 0.1 to 30MPa. The rate of oxygen consumption and behaviour in response to varying temperature/pressure combinations were assessed. Rates of oxygen consumption were primarily affected by temperature. Low rates of oxygen consumption were observed at 5 and 10°C across all pressures and were not statistically distinct (P0.639). From 10 to 30°C, the rate of oxygen consumption increased with temperature; this increase was statistically significant (P<0.001). Palaemonetes varians showed an increasing sensitivity to pressure with decreasing temperature; however, shrimp were capable of tolerating hydrostatic pressures found outside their normal bathymetric distribution at all temperatures. 'Loss of equilibrium' (LOE) in ≥50% of individuals was observed at 11MPa at 5°C, 15MPa at 10°C, 20MPa at 20°C and 21MPa at 30°C. From 5 to 20°C, mean levels of LOE decreased with temperature; this was significant (P<0.001). Low mean levels of LOE were observed at 20 and 30°C and were not distinct (P0.985). The physiological capability of P. varians to tolerate a wide range of temperatures and significant hydrostatic pressure is discussed.

“…As the thermal acclimation period of adult stages of M. rosenbergii was unknown, other life stages were considered. M. rosenbergii post larvae were completely acclimated after four weeks of acclimation (Herrera et al, 1998). Therefore we assumed our experimental animals were completely acclimated prior to CTM tests.…”

“…The critical thermal method (CT max and CT min ) is frequently used to estimate the scope of thermal tolerance (also known as thermal scope) of an organism (Diaz-Herrera et al, 1998;Ford and Beitinger, 2005). This estimation directly quantifies the temperatures at which an aquatic organism loses equilibrium.…”

SUMMARYParental influences are a potentially important component of transgenerational transfer of phenotype in vertebrates. This study examined how chronic hypoxic exposure on adult zebrafish (Danio rerio) affected the phenotype of their offspring. Separate adult populations were exposed to hypoxia (13.1kPa O 2 ) or normoxia (21.1kPa O 2 ) for periods ranging from 1 to 12weeks. Adults were then returned to normoxia and bred within experimental groups. Adult fecundity and egg characteristics (volume of egg, yolk and perivitelline fluid) were assessed. Subsequently, larval body length, time to loss of equilibrium in severe hypoxia (~4kPa O 2 ), and critical thermal minima (CT min ) and maxima (CT max ) were measured at 6, 9, 12, 15, 18, 21 and 60days post-fertilization (d.p.f.). Adult fecundity was depressed by hypoxic exposure. Egg component volumes were also depressed in adults exposed to 1-2weeks of hypoxia, but returned to control levels following longer hypoxic exposure. Adult hypoxic exposures of >1week resulted in longer body lengths in their larval offspring. Time to loss of equilibrium in severe hypoxia (i.e. hypoxic resistance) in control larvae decreased from 6 to 12d.p.f., remaining constant thereafter. Notably, hypoxic resistance from 6 to 18d.p.f. was ~15% lower in larvae whose parents were exposed to just 1week of chronic hypoxia, but resistance was significantly increased by ~24-30% in 6-18d.p.f. larvae from adults exposed to 2, 3 or 4weeks of hypoxia. CT min (~10-12°C) and CT max (~39.5°C) were unchanged by parental hypoxic exposure. This study demonstrates that parental hypoxic exposure in adult zebrafish has profound epigenetic effects on the morphological and physiological phenotype of their offspring.
