Causes and consequences of thermal tolerance limits in rocky intertidal porcelain crabs, genus petrolisthes.
Vertical zonation of intertidal organisms, from the shallow subtidal to the supralittoral zones, is a ubiquitous feature of temperate and tropical rocky shores. Organisms that live higher on the shore experience larger daily and seasonal fluctuations in microhabitat conditions, due to their greater exposure to terrestrial conditions during emersion. Comparative analyses of the adaptive linkage ...
متن کاملA comparative analysis of the upper thermal tolerance limits of eastern Pacific porcelain crabs, genus Petrolisthes: influences of latitude, vertical zonation, acclimation, and phylogeny.
Marine intertidal organisms are subjected to a variety of abiotic stresses, including aerial exposure and wide ranges of temperature. Intertidal species generally have higher thermal tolerance limits than do subtidal species, and tropical species have higher thermal tolerance limits than do temperate species. The adaptive significance of upper thermal tolerance limits of intertidal organisms, h...
متن کاملEvolutionary history and adaptive significance of respiratory structures on the legs of intertidal porcelain crabs, genus Petrolisthes.
Semiterrestrial and terrestrial crabs have evolved multiple strategies for aerial respiration. An uncommon strategy for aerial respiration is seen in porcelain crabs, genus Petrolisthes, where decalcified areas on the meral segments of the walking legs are used as respiratory structures. Here, the evolutionary history and adaptive significance of these structures in porcelain crabs is examined....
متن کاملA comparative analysis of plasticity of thermal limits in porcelain crabs across latitudinal and intertidal zone clines
The effect of thermal acclimation on cardiac thermal performance limits was examined in congeneric species of porcelain crabs (genus Petrolisthes) from temperate and subtropical habitats. In vivo heart rate was monitored using impedance electrodes during thermal ramps (0.1 8C/min) where temperature either increased or decreased from an intermediate temperature to thermal extremes. Arrhenius plo...
متن کاملAdaptation to temperature stress and aerial exposure in congeneric species of intertidal porcelain crabs (genus Petrolisthes): correlation of physiology, biochemistry and morphology with vertical distribution
We examined physiological and biochemical responses to temperature and aerial exposure in two species of intertidal porcelain crabs (genus Petrolisthes) that inhabit discrete vertical zones. On the shores of the Northeastern Pacific, P. cinctipes (Randall) occurs under rocks and in mussel beds in the mid to high intertidal zone and P. eriomerus (Stimpson) occurs under rocks in the low intertida...
