“…This group generally has high critical temperatures that tend to correlate well with their vertical distribution in the intertidal environment (e.g. Southward, 1958;Simpson, 1976;Underwood, 1979;Somero, 2002;Salas et al, 2014). In some intertidal snails, particularly from the clade Littorinimorpha, the tolerance extends to metabolism, as the increase in resting ṀO 2 (ṀO 2,rest ) with temperature only breaks down at very high temperatures (e.g.…”

Tropical coral reef organisms are predicted to be especially sensitive to ocean warming because many already live close to their upper thermal limit, and the expected rise in ocean CO 2 is proposed to further reduce thermal tolerance. Little, however, is known about the thermal sensitivity of a diverse and abundant group of reef animals, the gastropods. The humpbacked conch (Gibberulus gibberulus gibbosus), inhabiting subtidal zones of the Great Barrier Reef, was chosen as a model because vigorous jumping, causing increased oxygen uptake (Ṁ O2 ), can be induced by exposure to odour from a predatory cone snail (Conus marmoreus). We investigated the effect of present-day ambient (417-454 µatm) and projected-future (955-987 µatm) P CO2 on resting (Ṁ O2,rest ) and maximum (Ṁ O2,max ) Ṁ O2 , as well as Ṁ O2 during hypoxia and critical oxygen tension (P O2,crit ), in snails kept at present-day ambient (28°C) or projectedfuture temperature (33°C). Ṁ O2,rest and Ṁ O2,max were measured both at the acclimation temperature and during an acute 5°C increase. Jumping caused a 4-to 6-fold increase in Ṁ O2 , and Ṁ O2,max increased with temperature so that absolute aerobic scope was maintained even at 38°C, although factorial scope was reduced. The humpbacked conch has a high hypoxia tolerance with a P O2,crit of 2.5 kPa at 28°C and 3.5 kPa at 33°C. There was no effect of elevated CO 2 on respiratory performance at any temperature. Long-term temperature records and our field measurements suggest that habitat temperature rarely exceeds 32.6°C during the summer, indicating that these snails have aerobic capacity in excess of current and future needs.

“…As global temperatures rise, there is increasing concern about the ability of ectothermic animals to survive in their warming environments and considerable effort is being expended to identify the physiological traits that may be of greatest importance in adapting to rising temperatures and to learn how these traits differ within the species (Somero 2010). Ectothermic animals use a combination of behavioral and physiological mechanisms to maintain their body temperatures within a narrow range, even under varied environmental conditions (Salas et al 2014). Behavioral thermoregulation can be adaptive in two complementary ways: (1) It can help an organism avoid extreme heat or cold that could be damaging or even lethal (Kelsch & Neill 1990) and (2) it can increase the time an animal spends at optimal physiological temperatures (Huey et al 2003).…”

2015) The effects of thermal acclimation on the behavior, thermal tolerance, and respiratory metabolism in a crab inhabiting a wide range of thermal habitats (Cancer antennarius Stimpson, 1856, the red shore crab), Marine and Freshwater Behaviour and Physiology, 48:2, 89-101,The preferred temperature of Cancer antennarius determined with the acute method was 15.2°C, and with the gravitation method was 15.9 ± 1.9 in the day cycle and 13.2 ± 0.6°C in the night cycle. The critical thermal maximum increased as the acclimation temperature was increased (p < 0.05); the thermal tolerance interval was 1.3, indicating that this species has a low tolerance indicative that it has evolved in highly stable environments. The acclimation response ratio for adults had an interval of 0.10-0.30. These values allow us to characterize this species as inhabiting cold and temperate regions. The oxygen consumption rates increased significantly (p < 0.05) from 6.57 to 9.92.0 mg O 2 kg −1 h −1 wet weight as the acclimation temperature increased from 15 to 24°C. The range of temperature coefficient (Q 10 ) between 15 and 18°C was the lower than 1.70 and corresponds with the intervals of preferred temperature.

“…These variations directly affect the physiological behaviour of organisms. Investigations from several Tegula species suggest an adaptive differentiation to diverse temperatures, which is observed in the differences in protein synthesis (Somero, 2002), demonstrating the genus acclimatisation to diverse distribution ranges (Salas et al 2014;Tomanek, 2002). Furthermore, other studies in Antarctic species from the Trochidae family-specifically Margarella antarcticareveal a positive correlation with latitude; variable that is also related with fertility and food availability (Linse et al 2006).…”

La gran variabilidad de los ambientes marinos en Chile está asociada a la longitud de su costa, la cual está regulada por diversos procesos oceanográficos que perfilan la distribución, abundancia y morfología de las especies marinas. Tegula atra es un gasterópodo marino de gran distribución en el Pacífico sur, cualidad que le permite ser un buen modelo de estudio para evaluar la variación de su tamaño corporal respecto a su distribución latitudinal. Un total de 236 individuos fueron recolectados en siete sitios de muestreo entre 41,6 ° ~ 53,6 °S. La relación entre el peso, la talla (media geométrica) y su distribución latitudinal fue evaluada de acuerdo con regresiones de Pearson y de cuantiles. En relación con la latitud, se observó una correlación positiva y sustancial (Pearson) entre el peso y la talla (p > 0,05) al desplazarse hacia el sur. Los resultados de la regresión de cuantiles reflejaron que tanto la pendiente como el valor R2 son significativos para la latitud con las dos variables analizadas (peso, media geométrica). Entre los factores que afectan al tamaño corporal de T. atra, se sugiere una diferenciación adaptativa de este género a diferentes temperaturas -lo que ya se ha observado en especies antárticas-. Esto revela una interacción entre la latitud, la fertilidad y el suministro de alimento, condición que se refleja en T. atra en la ecorregión subantártica. Sin embargo, el estudio de las zonas intermedias en el sur de Chile y la interacción con otros factores abióticos (por ejemplo, la profundidad) puede dilucidar estas variaciones en el tamaño corporal.
