“…The SMR value in the present study may nevertheless be slightly higher than found by Ern et al (Ern et al, 2013), which may be a result of our protocol, kept short to avoid the very rapid increase in background Ṁ O2 due to the bacterial growth that inevitably becomes very evident above 33°C. The Q 10 for SMR in the present study is 2.3 and is within the range 2.0-2.4 reported on M. rosenbergii in the literature (Chen and Kou, 1996;Manush et al, 2004). We conclude therefore that while the SMR values reported here may be slightly overestimated, this overestimation would have resulted in a similar underestimation of aerobic scope and that the conclusion that this species retains a large percentage of its aerobic scope up to a few degrees below T crit is valid.…”

In aquatic environments, rising water temperatures reduce water oxygen content while increasing oxygen demand, leading several authors to propose cardiorespiratory oxygen transport capacity as the main determinant of aquatic animal fitness. It has also been argued that tropical species, compared with temperate species, live very close to their upper thermal limit and hence are vulnerable to even small elevations in temperature. Little, however, is known about physiological responses to high temperatures in tropical species. Here we report that the tropical giant freshwater shrimp (Macrobrachium rosenbergii) maintains normal growth when challenged by a temperature rise of 6°C above the present day average (from 27°C to 33°C). Further, by measuring heart rate, gill ventilation rate, resting and maximum oxygen uptake, and hemolymph lactate, we show that oxygen transport capacity is maintained up to the critical maximum temperature around 41°C. In M. rosenbergii heart rate and gill ventilation rate increases exponentially until immediately below critical temperatures and at 38°C animals still retained more than 76% of aerobic scope measured at 30°C, and there was no indication of anaerobic metabolism at the high temperatures. Our study shows that the oxygen transport capacity is maintained at high temperatures, and that other mechanisms, such as protein dysfunction, are responsible for the loss of ecological performance at elevated temperatures.

“…This is considerably lower than the minimal thermal limits of other adult palaemonids reported to date, i.e. 20.5-23.0°C for Macrobrachium tenellum (Rodríguez and Ramirez, 1997), from 11.0±0.15 to 16.2±0.52°C for M. acanthurus (Díaz et al, 2002) and 14.9-16.9°C for M. rosenbergii (Manush et al, 2004). However, these other palaemonids are tropical species and the lowest acclimation temperature tested in the above studies was 20°C.…”

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.

“…Increased availability of antioxidative enzymes like superoxide dismutase to minimize oxidative stress (Portner, 2002) and increase the animal competence of effect of temperature and higher bioavailability of zinc at higher temperature (Phillips, 1978), this indicates that the free radicals are effectively scavenged by the SOD-1. Metabolism is also dependent on acclimation temperature, acclimation period and species Manush et al, 2004). The role of Zn (II) in Cu-Zn SODs is structural rather than functional.…”
