Here we used locally adapted populations of the intertidal copepod Tigriopus californicus to investigate these interactions in a marine ectotherm. Although plasticity at one life stage may influence plasticity at another life stage, relatively little is known about these interactive effects for thermal tolerance. For organisms in warming aquatic habitats, upper thermal tolerance is likely to be a key trait, and many organisms express plasticity in this trait in response to developmental or adulthood temperatures. Given the accelerating rate of climate change, plasticity may be particularly important. In response to rapid environmental change, organisms rely on both genetic adaptation and phenotypic plasticity to adjust key traits that are necessary for survival and reproduction. Together, these results indicate that developmental effects may have substantial impacts on upper thermal tolerance plasticity in adult ectotherms. Differences in the capacities to maintain ATP synthesis rates and to induce heat shock proteins at high temperatures, two likely mechanisms of local adaptation in this species, were consistent with changes in CTmax due to phenotypic plasticity, which suggests that there is likely mechanistic overlap between the effects of plasticity and adaptation. This pattern was identical across four populations, suggesting that local thermal adaptation has not shaped this effect among these populations. After development at 25☌, CTmax was plastic in adults, whereas no adulthood plasticity in this trait was observed after development at 20☌. We found that low latitude populations had greater critical thermal maxima (CTmax) than high latitude populations, and variation in developmental temperature altered CTmax plasticity in adults. Here we used locally adapted populations of the copepod Tigriopus californicus to investigate these potential effects in an intertidal ectotherm. Although plasticity at one life stage may influence plasticity at another life stage, relatively little is known about this possibility for thermal tolerance.

In response to environmental change, organisms rely on both genetic adaptation and phenotypic plasticity to adjust key traits that are necessary for survival and reproduction. auratus as an experimental tool useful to investigate mechanisms that could be difficult to explore using more conventional animal models and complex cardiac designs. The purpose of this review is also to emphasize the power of the heart of C. auratus finely regulate the cardiac function under basal conditions and under environmental challenges, this review highlights the remarkable flexibility of the goldfish heart in relation not only to the basic morpho-functional design and complex neuro-humoral traits, but also to its extraordinary biochemical-metabolic plasticity and its adaptive potential. However, an overview on the existing current knowledge is not yet available. A growing literature is available to illustrate the complex networks involved in the modulation of the goldfish cardiac performance, also in relation to the influence of environmental signals. More recently, the research possibilities offered by the goldfish are further expanded to cardiac studies. Among fishes, the cyprinid Carassius auratus (goldfish) is largely used for studies on comparative and evolutionary endocrinology, neurobiology, adaptive and conservation physiology, as well as for translational research aimed to explore mechanisms that may be useful in an applicative biomedical context.
