The Petrolisthes galathinus complex: species boundaries based on color pattern, morphology and molecules, and evolutionary interrelationships between this complex and other Porcellanidae (Crustacea:
The molecular and morphometric results support the validity of the species in the complex, and of color pattern for their distinction, and the close relationship between the complex and the putative ancenstral porcellanid Parapetrolisthes tortugensis was indicated by the molecular and larval-morphology results.
Geographic and depth distributional patterns of western Atlantic Porcellanidae (Crustacea: Decapoda: Anomura), with an updated list of species
A relationship was observed between depth distributions and geographic ranges of western Atlantic porcellanids: “sublittoral’ species have wide geographic ranges, presumably as result of greater dispersal potential and ability to colonise a variety of ecological habitats; “intertidal” species have narrow geographic ranges and are likely to have lower dispersal ability and narrow ecological requirements.
Studies on the origin and distribution of palytoxin in a Caribbean coral reef.
In coral reefs of the Caribbean Sea (Colombia) palytoxin (PTX) has been detected in zoanthid species of the genera Palythoa and Zoanthus by assaying the delayed haemolysis in human erythrocytes
Trematodes of birds from Northern Columbia
SummaryFourteen digenean trematode species, including two new species, are described from marsh and shore birds from North Columbia. Described as new areDrepanocephalus parvicephalus n.sp.
The Boreholes of the Sea Urchin Genus Echinometra (Echinodermata: Echinoidea: Echinometridae) as a Microhabitat in Tropical South America*
The effects of boring activities of Echinometra vunbrunri A. Agassu in the Colombian Pacific is examined, finding that the associates live underneath the echinoid on the bottom of the borehole, where they find shelter from exposure and predators.
Redescription of Petrolisthes militaris (Heller, 1862), with description of a new species from the Indo-West Pacific (Decapoda, Porcellanidae)
Phylogenetic analyses of a dataset based on DNA sequences of a fragment of the mitochondrial COI gene from individuals representing the two forms support the separation of these into two species.
A new mangrove-inhabiting porcelain crab of the genus Enosteoides (Crustacea: Decapoda: Anomura) from Puerto Princesa Bay, Palawan, the Philippines
A mangrove-inhabiting porcelain crab, Enosteoides philippinensis sp. nov., is described based on material collected from Palawan Island, the Philippines. It is the fifth species of the genus and
Resistance and vulnerability of crustaceans to cytolytic sea anemone toxins.
Crustaceans (Mithraculus, Neopetrolisthes, Periclimenes, Stenorhynchus sp.) living in association with sea anemones, shore crabs and brine shrimps were found to be resistent to the exposure of cytolyticSea anemone toxins and to other membrane-active compounds such as gramicidin A and saponin.
Ecology of the Endemic Land Crab Johngarthia malpilensis (Decapoda: Brachyura: Gecarcinidae), a Poorly Known Species from the Tropical Eastern Pacific1
Johngarthia malpilensis showed high mobility, with crabs covering distances over 450 m in a few days on highly irregular surfaces, and is one of the most important components of Malpelo's food web.
Life habits and functional morphology of the sediment infaunal spongesOceanapia oleracea andOceanapia peltata (Porifera, Haplosclerida)
Based on the observations on Oceanapia, the water flow model forDisyringa proposed by Fry and Fry (1979) is reconsidered.
