Temperature-adaptive physiological variation plays important roles in latitudinal biogeographic patterning and in setting vertical distributions along subtidal-to-intertidal gradients in coastal marine ecosystems. Comparisons of congeneric marine invertebrates reveal that the most warm-adapted species may live closer to their thermal tolerance limits and have lower abilities to increase heat tolerance through acclimation than more cold-adapted species. In crabs and snails, heart function may be of critical importance in establishing thermal tolerance limits. Temperature-mediated shifts in gene expression may be critical in thermal acclimation. Transcriptional changes, monitored using cDNA microarrays, have been shown to differ between steady-state thermal acclimation and diurnal temperature cycling in a eurythermal teleost fish (Austrofundulus limnaeus). In stenothermal Antarctic notothenioid fish, losses in capacity for temperature-mediated gene expression, including the absence of a heat-shock response, may reduce the abilities of these species to acclimate to increased temperatures. Differences among species in thermal tolerance limits and in the capacities to adjust these limits may determine how organisms are affected by climate change.

Geographic variation in the upper thermal limits of an intertidal snail: implications for climate envelope models. (2009, background): “Intertidal marine organisms are thought to be particularly vulnerable to global warming, because some of these species appear to be currently living near the edge of their upper thermal limits with little ability to further increase heat tolerance through acclimation (Stillman 2003, Somero 2005).”
Geographic Variation in Temperature Tolerance as an Indicator of Potential Population Responses to Climate Change (2011, background): “, 2007; Bonebrake and Mastrandrea, 2010) and have lower acclimation potentials (Stillman, 2003; Somero, 2005; Stenseng et al., 2005; Ghalambor et al., 2006).”
Gene expression in the intertidal mussel Mytilus californianus: physiological response to environmental factors on a biogeographic scale (2008, positive): “This study is preceded by other research in experimental biogeography where gene expression of single genes was examined as a means to assess physiological response to the marine environment (e.g. Place et al. 2004, Somero 2005, Lovett et al. 2006, Todgham et al. 2006, Bystriansky et al. 2007).”

All Other Uses, Reproduction and Distribution, including without Limitation Comm (2005, neutral): “NMR spectra of molecules partially oriented in an anisotropic liquid-crystalline environment provide detailed information about interactions that cannot be observed in the isotropic phase.”
Seasonal thermal tolerance in marine Crustacea (2006, background): “Despite being euythermal, it has been suggested that warm adapted intertidal species may be in greatest jeopardy from slightly higher than normal environmental temperatures since they frequently live closer to their thermal limits (Stillman, 2003; Somero, 2005).”
Dispersal ability rather than ecological tolerance drives differences in range size between lentic and lotic water beetles (Coleoptera: Hydrophilidae) (2012, background): “Similarly, establishment ability, as determined by breadth of the fundamental niche, has been proposed to be one of the main factors shaping the geographical ranges of species (Brown, 1984), and, of the many possible niche dimensions, thermal tolerance shows a strong correlation with distributional ”
Thermal tolerance and geographical range size in the Agabus brunneus group of European diving beetles (Coleoptera: Dytiscidae) (2007, background): “A limited ability to adjust UTT to environmental temperature changes is likely to affect species’ responses under the current global warming scenario (Stillman, 2003; Somero, 2005).”
Local adaptation in marine invertebrates. (2011, background): “This problem may be especially important for corals and intertidal invertebrates, some of which appear to be living close to the edge of their upper thermal limits (Hughes et al. 2003; Somero 2005, 2010).”
Cold shock and fish (2008, background): “Optimal temperature ranges, as well as upper and lower lethal temperatures, vary widely between and among species and are dependent on genetics, developmental stage and thermal histories (Beitinger et al., 2000; Somero, 2005).”
Hyperoxia alleviates thermal stress in the Antarctic bivalve, Laternula elliptica: evidence for oxygen limited thermal tolerance (2006, background): “Previous analyses have largely focused on mechanisms responsible for thermal limitation or those conveying tolerance and adaptation (e.g. Somero 2005); analyses addressing the mechanistic background of performance at the whole animal level are scarce.”
The physiology of climate change: how potentials for acclimatization and genetic adaptation will determine ‘winners’ and ‘losers’ (2010, background): “These ‘apple to apple’ comparisons allow adaptive differences among species to be clearly delineated, without ambiguities arising from phylogenetic effects (Stillman and Somero, 2000; Hochachka and Somero, 2002; Somero, 2005).”
Can amphibians take the heat? Vulnerability to climate warming in subtropical and temperate larval amphibian communities (2012, background): “In this context, a crucial question is to identify the species and communities currently living close to their upper thermal physiological limits, and that are exposed to higher risk of suffering physiological stress (Somero, 2005; Helmuth et al., 2010).”
Phenotypic variance, plasticity and heritability estimates of critical thermal limits depend on methodological context (2009, background): “Journal compilation © 2008 British Ecological Society, Functional Ecology , 23 , 133–140 The rate of temperature change adopted in a trial appears to have an especially pronounced effect on estimates of critical thermal limits – a widely used measure of thermal activity range (Lutterschmidt & Hutchi”
