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 new species of porcelain crab, Petrolisthes tuerkayi n. sp. (Crustacea: Anomura: Porcellanidae), from the Persian Gulf.
A new species of porcellanid crab, Petrolisthes tuerkayi n. sp., is described from the Persian Gulf. The new species is closely related to P. rufescens Heller, 1861, but is easily distinguishable by having three or four large spines distally on the posterior margin of the carpus of chelipeds, whereas the posterior margin of the cheliped merus in P. rufescens is unarmed.
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 کاملThe Effect of Sex, Size and Habitat on the Incidence of Puncture Wounds in the Claws of the Porcelain Crab Petrolisthes Cinctipes (anomura: Porcellanidae)
Many porcelain crabs have an unusual claw (cheliped) form that is broad, flat and thin. This seemingly flimsy form suggests claws may be used more for display than for feeding or aggressive interactions. However, in the flat-topped porcelain crab Petrolisthes cinctipes, one of the most abundant intertidal crustaceans on the Pacific coast of North America, we observed a high proportion of indivi...
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...
