“…Moreover, although there is still some debate about the possibility of accurately predicting incipient lethal temperature from Ct max , various studies suggest that the former are several degrees lower than the latter: in a study of seven fish species, Rajaguru (Rajaguru, 2002) found that incipient lethal temperatures were 3-5°C lower than the corresponding Ct max . Closer to M. fortunata, Nelson and Hooper (1982) showed that incipient lethal temperature is <33°C for the glass shrimp Palaemonetes kadiakensis, while the measured Ct max was ca. 37°C at least.…”

“…One is the 'loss of righting reflex' (LRR) response, upon checking an organism's ability to recover its normal 'upright' position, after probing by the experimenter (Cuculescu et al, 1998). In the case of shrimps, several studies proposed the loss of equilibrium (LOE) response as an end-point for Ct max determination (Nelson and Hooper, 1982;Hernandez et al, 1996;Diaz et al, 1998;Diaz et al, 2002;Manush et al, 2004;Selvakumar and Geraldine, 2005), since this corresponds to a loss of balance of the shrimp, an equivalent of the LRR response but without active probing by the experimenter. Although the correspondence of these responses with the definition of Ct max is currently debated, they are nevertheless reliable indicators of imminent heat coma and death.…”

“…Several studies on the Ct max (based on the LOE response, with heating rates in the range 0.3-1°C·min -1 ) of five tropical freshwater caridean shrimp species, each acclimated at different temperatures ranging from 20°C to 35°C (usually for 1 month), yielded values in the 34-43°C range (Nelson and Hooper, 1982;Hernandez et al, 1996;Diaz et al, 1998;Diaz et al, 2002;Manush et al, 2004;Selvakumar and Geraldine, 2005). These shrimps all live in water where the temperature is rarely cooler than 20°C, most of the time is about 28-30°C, and may reach 35°C.…”

SUMMARY The shrimp Mirocaris fortunata is a hydrothermal vent species that is found at most vent-sites along the Mid-Atlantic Ridge. This endemic species is found across a hydrothermal gradient, with thermal conditions ranging from 2–9°C in ambient seawater to fairly warm values of about 25°C. We performed in vivo experiments on M. fortunata specimens originating from different sites and depths (850 m to 2300 m), both at atmospheric pressure and in pressurized aquaria, to characterise the upper thermal limits of this species. Atmospheric pressure results show that thermal physiology should be studied at each population's native pressure. At in situ pressure, shrimps from Menez Gwen (850 m depth) and Lucky Strike(1700 m depth) do not survive temperatures of 39°C, and the `loss of equilibrium' response suggests that their critical thermal maximum(Ctmax), is about 36±1°C for both sites. This value is similar to those found for another vent shrimp, Rimicaris exoculata, which is thought to be a more temperature-resistant organism,so temperature resistance does not appear to be a crucial factor for explaining differences in distribution of shrimp species in a given vent site. Finally, the data for both vent shrimps are also comparable to those of other non-vent tropical caridean species.

“…All test organisms were acclimated to 17°C amphipods (Buchanan et al, 1988), isopods (Lagerspetz, 2003), decapods (Nelson & Hooper, 1982;Manush et al, 2004;Selvakumar & Geraldine, 2005), odonates , plecopterans (Ernst et al, 1984) and trichopterans (Moulton et al, 1993). This study has extended knowledge to an additional six orders including Gastropoda, Coleoptera, Diptera, Ephemeroptera, Hemiptera and Megaloptera (Table 5) as well as expanding the taxa within the published orders.…”

Critical Thermal Maxima of aquatic macroinvertebrates: towards identifying bioindicators of thermal alteration

2011

Water temperature is an important abiotic driver of aquatic ecosystems. It influences many aspects of an organism's existence including its growth, feeding and metabolic rates; emergence; fecundity; behaviour and ultimately survival. All organisms have an optimum temperature range within which they survive and are able to thrive. Determining upper thermal limits provides insight into the relative sensitivity of organisms to elevated temperatures. Thermally sensitive taxa may be useful as bioindicators of thermal alteration and used in the generation of target thermal thresholds for aquatic systems. This study determined the upper thermal limit (CTmax) of a range of aquatic macroinvertebrates from rivers in the south-western Cape, South Africa, using the dynamic Critical Thermal Method. The study focused on the taxonomic level of family as an initial screening tool for ranking thermal sensitivity. Of the 27 families examined, four were both thermally sensitive and highly suitable as test organisms, including Paramelitidae, Notonemouridae, Teloganodidae and Philopotamidae. Five families were moderately sensitive and highly suitable, including Palaemonidae, Heptageniidae, Leptophlebiidae, Corydalidae and Aeshnidae. Preliminary experiments to determine potential sources of variation in CTmax revealed that thermal sensitivity was relatively uniform within families, but that acclimation temperature influenced CTmax. Further investigation of the influence of thermal history, acclimation temperature and rate of temperature change on CTmax is necessary. Target water temperatures for river management will be derived using CTmax data, in addition to longer duration experimental data, which will be linked to in situ temperature data.

“…Determinations of the CTMax were performed between 9:00 and 14:00 h. The heating rate used was 1 1C min À 1 (Lutterschmidt andHutchison, 1997a, 1997b). The stress event registered was Loss of Righting Response (LRR) when the shrimp was on its back and could not recover its upright posture, or remained reclined at a 901 angle (Nelson and Hooper, 1982). When shrimp reached the end point, they were removed from the aquarium, and a 10 mL sample of hemolymph was taken with an automatic pipette through the thoracic-abdominal membrane (previously dried with absorbent paper), same procedure was made for the control organisms.…”
