One of the most poorly known books on natural history was a volume by Bengt Andersson Euphrasén in 1795 that gave an account of the fauna of Saint Barthélemy in the Caribbean Lesser Antilles (ca. 17°53′52.47′′N 62°51′2.0′′W). The only taxon he reported that has been recognized as an original description is a plant, Iresine angustifolia (Euphrasén, 1795) (family Amaranthaceae), and this only hap...

The level of the heavy metal in green tiger shrimp (Penaeus semisulcatus) and crab (Portunus pelagicus) caught off the Persian Gulf near Bushehr province were investigated. This study was performed to evaluate instrumental neutron activation analysis (INAA) to analyze heavy metal concentration in crab and shrimp whole body tissue. The order of the swimmer crab and shrimp heavy metal concentrati...

Portunus pelagicus was collected at regular intervals from two marine embayments and two estuaries on the lower west coast of Australia and from a large embayment located approximately 800 km farther north. The samples were used to obtain data on the reproductive biology of this species in three very different envi­ ronments. Unlike females, the males show a loosening of the attachment of the a...

The aim of this study was to determine the diets of Portunus pelagicus in the large Peel-Harvey and Leschenault estuaries in south-western Australia in order to ascertain whether the dietary composition of this crab changes with body size during two different moult stages and differs between the two estuaries. Portunus pelagicus, ranging in age and carapace width from ca. 2 months and 12 mm to ...
