The 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 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 کاملTemperature and acidification variability reduce physiological performance in the intertidal zone porcelain crab Petrolisthes cinctipes.
We show here that increased variability of temperature and pH synergistically negatively affects the energetics of intertidal zone crabs. Under future climate scenarios, coastal ecosystems are projected to have increased extremes of low tide-associated thermal stress and ocean acidification-associated low pH, the individual or interactive effects of which have yet to be determined. To character...
متن کاملConstruction and characterization of EST libraries from the porcelain crab, Petrolisthes cinctipes.
The thermal phenotype of an organism (heat and cold tolerance, thermal range, and thermal plasticity) is an essential feature of how the organism performs across thermal environments and in response to thermal stress. Porcelain crabs are of interest in addressing questions of thermal phenotype because of their high species diversity and the large variation in thermal phenotype among species, as...
متن کاملA cDNA microarray analysis of the response to heat stress in hepatopancreas tissue of the porcelain crab Petrolisthes cinctipes.
Intertidal zone organisms experience thermal stress during periods of low tide, and much work has shown that induction of heat shock proteins and ubiquitination occurs in response to this stress. However, less is known of other cellular pathways that are regulated following thermal stress in these organisms. Here, we used a functional genomics approach to identify genes that were up- and downre...
