Effect of the burrowing crab Chasmagnathus granulata (Dana) on the benthic community of a SW Atlantic coastal lagoon
This study evaluated the effect of the burrowing crab Chasmagnathus granulata on the benthic community in mudflats of the Mar Chiquita coastal lagoon (Argentina, 378 459 S, 578 269 W). A significantly higher abundance of the polychaete Laeonereis acuta was found inside the C. granulata crab bed than outside. However, L. acuta abundance decreased in summer probably due to the greater activity of...

متن کاملSurface expression of NMDA receptor changes during memory consolidation in the crab Neohelice granulata.
The aim of the present study was to analyze the surface expression of the NMDA-like receptors during the consolidation of contextual learning in the crab Neohelice granulata Memory storage is based on alterations in the strength of synaptic connections between neurons. The glutamatergic synapses undergo various forms of N-methyl-D aspartate receptor (NMDAR)-dependent changes in strength, a proc...
متن کاملDietary copper effects in the estuarine crab, Neohelice (Chasmagnathus) granulata, maintained at two different salinities.
We analyzed the dietary copper effects in the estuarine crab Neohelice (Chasmagnathus) granulata and its interaction with water salinity. Crabs were maintained at 2 per thousand and 30 per thousand salinity for 5 weeks and they were fed with commercial food supplemented with the green alga Scenedesmus vacuolatus previously exposed to copper. No mortalities were observed, but crabs maintained at...
متن کاملThe effect of the SW Atlantic burrowing crab Chasmagnathus granulatus on the intertidal razor clam Tagelus plebeius
The deposit feeding burrowing crab Chasmagnathus granulatus and the suspension feeding burrowing clam Tagelus plebeius occur sympatrically in the intertidal flats of the south western Atlantic estuarine environments. Common ecological theory predicts negative effects of deposit feeder bioturbation on co-occurring suspension feeders up to complete exclusion of the latter. By means of descriptive...
