“…McGaw (2003) found that the purple shore crab, Hemigrapsus nudus, had a high CTMax, which ranged between 31 and 34°C. However, decapods with higher CTMax values had poorer acclimatization capacity than decapods with lower CTMax (Hopkin et al, 2006). Organisms with higher CTMax are more susceptible to an increase in temperature since they already live at or close to their maximum thermal tolerance capacities (Stillman, 2003;Somero, 2011).…”

“…Hopkin et al (2006) investigated the seasonal critical thermal maxima (CTMax) of eight crustaceans (Cancer pagurus, Carcinus maenas, Hyas araneus, Liocarcinus depurator, Munida rugosa, Necora puber, Nephrops norvegicus and Pagurus bernhardus) in the United Kingdom, and found the temperature at which these crustaceans lost the ability to right themselves after being turned over, to range between 20°C and 34°C, with summer caught organisms (14°C-17°C) having significantly higher upper thermal tolerance values than winter caught organisms (9°C). McGaw (2003) found that the purple shore crab, Hemigrapsus nudus, had a high CTMax, which ranged between 31 and 34°C.…”

Abstract.Sedimentation and increasing temperature caused by human disturbances and global climate change are additive in their effects on coastal areas. To assess their influence on intertidal organisms, we studied the hermit crab, Pagurus samuelis, under acute temperature changes and shallow burial conditions. We applied three temperatures (5°C, 20°C, and 30°C) and two burial depths (3 cm and 6 cm) with a control at the surface (0 cm), and monitored survival, shell abandonment, and burial escape. Survival was primarily affected by temperature, with hermit crabs twice as likely to survive at 20°C than at 30°C, and at 5°C than at 30°C. The combined conditions of 30°C and 6 cm were the least favorable for survival. Hermit crabs which abandoned their shells were more likely to survive burial at 20°C and 30°C than those retaining their shells. Fewer hermit crabs abandoned their shells when exposed to 5°C than to 20°C and 30°C. Crabs buried at 6 cm were 85.0% less likely to abandon shells than those buried at 3 cm, and heavier shells were less readily abandoned than lighter shells. Although overall, 35% of hermit crabs escaped burial to the sediment surface, hermit crabs buried in the combined conditions of 30°C and 6 cm were significantly slower to reach the surface. Our results show that the combined stresses of temperature and burial can impact survival of hermit crabs in intertidal zones. While human activities, including dredging, industrial and domestic dumping, and coastal construction, result in relatively immediate increased inputs of sediment in coastal environments, climate change may endanger intertidal organisms, such as P. samuelis, living near their thermal tolerance over the long term, with both increasing temperature and sedimentation from more frequent storm events.

“…The small increase in CT Max between spring and summer, and the low variability around the CT Max , suggest that M. plagusius has limited physiological capacity to further increase its thermal tolerances (Somero 2010). This low acclimation capacity of thermal tolerances for species with high values of CT Max or other thermal tolerance metrics is also shown in the thermal tolerances of crustaceans (Stillman 2003, Hopkin et al 2006.…”

“…However, the proximate result is that CT Max of M. plagusius increases in summer, allowing M. plagusius to persist underneath a greater number of rocks. Understanding the capacity of a population to seasonally acclimatize its CT Max under field conditions is an understudied area of research and deserves more attention (but see Hopkin et al 2006, Sanabria et al 2013, especially given the growth of macrophysical models in determining large scale patterns in ecology (Chown and Gaston 2008, Gaston et al 2009, Kearney et al 2009. Often these models only use single values of thermal tolerances (although see Sunday et al 2011) or thermal tolerance values generated under laboratory acclimation conditions that do not capture seasonal variation in temperatures, food availability, reproductive status, field-relevant ramping rates and humidity that may all contribute to the thermal tolerances of a population.…”

Abstract. In environments where animals have a high probability of encountering temperatures close to their thermal limits, animals with the capacity to minimize the chances of encountering these temperatures will be advantaged. We investigated the physiological and behavioral mechanisms used by flat rock spiders, Morebilus plagusius, to avoid encountering lethal or sub-lethal temperatures on sandstone outcrops by measuring their critical thermal maximum (CT Max ) in spring and summer and quantifying their retreat rock use. Morebilus plagusius has a high CT Max , which acclimatizes seasonally (spring CT Max : 48.38 6 0.28C; summer CT Max : 49.68 6 0.38C). By measuring the operative temperatures available to spiders underneath rocks in spring and summer and quantifying retreat rock use by adult spiders we found that random use of rocks by spiders would frequently expose them to temperatures above their thermal tolerances, especially in summer. Spiders non-randomly used rocks as diurnal retreats, with rocks with a large area and a rock substratum being positively correlated with M. plagusius occupancy. Rocks large in area provided cooler daytime shelters than exfoliated rocks with smaller area. Morebilus plagusius uses both physiological and behavioral mechanisms for avoiding lethal temperatures, and neither physiological nor behavioral mechanisms alone are enough to mitigate the increased probability of encountering lethal temperatures in summer. Our results highlight the importance of an integrative approach, incorporating behavioral, ecological and physiological mechanisms in accessing how animals avoid lethal temperatures in thermally extreme environments.
