Survival and chloride ion regulation of the porcelain crab Petrolisthes armatus exposed to mercury
Marine Biology, 1974Acute toxicity bioassays conducted at various salinities demonstrated that mercury (as mercuric chloride) at low concentrations was lethal to Petrolisthes armatus. Ninety-six hour LC50 values varied from 50 to 64 parts per billion (ppb) of mercury, depending on test salinities. Lower salinities.

Estrutura populacional de Petrolisthes armatus (Gibbes) (Decapoda, Anomura, Porcellanidae) da Ilha do Farol, Matinhos, Paraná, Brasil [PDF]
Revista Brasileira De Zoologia, 1995 Population structure of the porcelain crab Petrolisthes armatus (Gibbes, 1850) from the rocky shore of the Farol isle (25o51'S, 48o32'W) was carried out in the following aspects: annual fluctuation of the density, distribution of the developmental stages and sexes over year round, size composition and recruiting period of juveniles into the population.

Biological Invasions, 2018
Biotic resistance by native predators can limit the geographic range and abundance of non-native species following introduction into an ecosystem. Here we tested the hypothesis that the strength of predation pressure varies with latitude and limits the abundance and northward expansion of the non-native green porcelain crab, Petrolisthes armatus, whose

Abstract The green porcelain crab Petrolisthes armatus is an abundant invader on intertidal oyster reefs along the southeastern coast of the United States. Its range expansion appears to be thermally limited and is predicted to shift poleward as water temperatures rise. Little is known about how P.

Population dynamics of the non-native crab Petrolisthes armatus invading the South Atlantic Bight at densities of thousands m2 [PDF]
Marine Ecology - Progress Series, 2007 The green porcelain crab Petrolisthes armatus recently invaded oyster reefs of the South Atlantic Bight. In 2 estuaries of coastal Georgia, USA, crab densities reached peak densities of 4000 to 11 000 crabs m -2 in some periods and locations. Densities generally were higher in the low versus the high intertidal and in the lower versus upper regions of ...

The gross morphology of the embryonic development of two porcelain crabs from distinct habitats, Petrolisthes robsonae (coastal lagoon) and P. armatus (sea shore intertidal) is described and illustrated at 48 hour intervals from oviposition to hatching. The development of the two species is compared with each other, since no information is available on

Increasing ocean temperatures have led to poleward range expansions of many marine organisms. The green porcelain crab, Petrolisthes armatus, was first reported on intertidal oyster reefs near Charleston, South Carolina in the mid-1990s, an expansion from its tropical to sub-tropical native range. In order to investigate the relative abundances of this

Since transport of planktonic larvae is essential to the maintenance and expansion of many marine species, we examined the spatial and temporal distribution of green porcelain crab Petrolisthes armatus (Gibbes, 1850) larvae and the possible underlying physical and behavioral mechanisms using a combination of field observations and numerical modeling ...

A description of the type specimen of Porcellana digitalis Heller, 1862, is provided, and its identity with Petrolisthes armatus (Gibbes, 1850) established. The type locality of Heller's species, "Gibraltar", like those of many other new species collected by the 1857-1859 "Novara" Expedition, is unreliable, and should be disregarded, unless supported ...
