The aim of this work was to gain knowledge about reproductive biology of the crab Armases rubripes (Rathbun, 1897) from an estuarine area of the Sepetiba Bay. Samples were taken monthly from February 2003 to January 2004 in the Sahy River estuary (22º56'S; 44º01'W), Rio de Janeiro, Brazil. The crabs were collected by hand during 15-minute catch-effort sessions conducted by two people. In the laboratory, the specimens were separated by sex, carapace width was measured and gonadal stage was checked macroscopically. A total of 830 individuals were caught - 304 males, 373 females (60 ovigerous females) and 153 juveniles. The ovigerous females were found almost year-round, except in November and April, showing a continuous reproductive period. They presented a... |

Two new species of sesarmid crabs are described from the mangroves of Timika in Papua (= Irian Jaya), Indonesia. Haberma kamora spec. nov. is the second species in the genus described from Singapore, differing from the type species in the form of its male first pleopods and possessing relatively more slender ambulatory legs. Parasesarma charis spec. nov. resembles P. erythrodactyla, P. tripectinis and to some extent, P. lepidum, but has different ambulatory leg proportions and a distinctive male first pleopod structure. Parasesarma acis Davie, 1993, is regarded as a junior synonym of P. tripectinis Shen, 1940. |

The potential long-term effects of altered salinity regimes on the bioenergetics of two ecologically important Kenyan mangrove crabs, Neosarmatium meinerti de Man, 1887 and Neosarmatium smithi H. Milne Edwards, 1853 were investigated in light of recent findings suggesting that groundwater redirection may alter salinity regimes in Kenyan mangroves. Although changes in groundwater may cause only small increases in salinities, these changes would be chronic and may impact crab populations already living above their optimal salinity. To assess potential impacts, fundamental physiological processes and hemolymph components were measured on animals acclimated to 16‰, 32‰, 48‰ and 65‰ for 4 weeks in a field laboratory. For comparative purposes, crabs were also... |
