| dietary copper absorption and excretion in three semi-terrestrial grapsoid crabs with different levels of terrestrial adaptation. | three species of phylogenetically related semi-terrestrial crabs (superfamily grapsoidea--sesarma rectum, goniopsis cruentata and neohelice granulata (formerly: chasmagnathus granulatus) with different degrees of terrestriality were studied to quantify the accumulation of copper (cu) in hemolymph, gills, hepatopancreas and antennal gland, and its excretion through the faeces. these crabs were fed for 15 days practical diets containing 0 (a), 0.5 (b), 1.0 (c), and 1.5% (d) of added cucl2 (corresp ... | 2008 | 18501679 |
| growth and reproduction of the mangrove crab goniopsis cruentata (latreille, 1803) (crustacea: decapoda: grapsidae) in southeastern brazil. | goniopsis cruentata is a common semi-terrestrial crab in brazilian mangroves and an important fishery resource for traditional communities in the northeastern brazilian coast. aiming to contribute to the knowledge about the species, this study evaluated the carapace width and weight growth curves, the relative growth of weight versus carapace width, and the temporal variation of gonadosomatic and hepatosomatic indices for the species. a total of 524 crabs were collected in a mangrove area of uba ... | 2015 | 26062120 |
| ascomycetous yeast communities of marine invertebrates in a southeast brazilian mangrove ecosystem. | the ascomycetous yeast communities associated with 3 bivalve mollusk, and 4 crab species were studied in the mangrove at coroa grande on sepetiba bay in rio de janeiro, brazil. these were made up mostly of diverse but sparse and apparently allochtonous yeast populations. the striking exception was a prevalent population of the species kluyveromyces aestuarii, which predominated the yeast communities of 2 detritus feeding crabs, sesarma rectum and uca spp., and the shipworm neoteredo reynei. howe ... | 1995 | 8546456 |
