A structure-function analysis of ion transport in crustacean gills and excretory organs.
Osmotic and ionic regulation in the Crustacea is mostly accomplished by the multifunctional gills, together with the excretory organs. In addition to their role in gas exchange, the gills constituteExpand

Evolution of osmoregulatory patterns and gill ion transport mechanisms in the decapod Crustacea: a review
Decapod crustaceans exhibit a wide range of osmoregulatory patterns and capabilities from marine osmoconformers to brackish and freshwater hyperregulators to terrestrial hyporegulators. The principalExpand

The distribution of fiddler crabs ( Uca ) along the coast of Brazil: implications for biogeography of the western Atlantic Ocean
To assess and analyse accurately their geographical distributions, fiddler crabs ( Uca ) from the Atlantic coast of Brazil were studied using field collections, museum specimens and literatureExpand

Differential adjustment in gill Na+/K+- and V-ATPase activities and transporter mRNA expression during osmoregulatory acclimation in the cinnamon shrimp Macrobrachium amazonicum (Decapoda,
SUMMARY We evaluate osmotic and chloride (Cl–) regulatory capability in the diadromous shrimp Macrobrachium amazonicum, and the accompanying alterations in hemolymph osmolality and [Cl–], gillExpand

Osmoregulation and respiratory metabolism in brazilian Macrobrachium (Decapoda, palaemonidae)
Abstract 1. 1. The effect of salinity (0, 7, 14, 21, 28 and 35‰) on osmoregulatory capability and metabolic rate in adult Macrobrachium acanthurus, M. heterochirus, M. olfersii and M. potiuna , wasExpand

Adaptive patterns of osmotic and ionic regulation, and the invasion of fresh water by the palaemonid shrimps.
To evaluate trends in the osmoregulatory behavior of neotropical, palaemonid shrimps, we investigated osmotic and ionic regulatory patterns in five species of Palaemon or Macrobrachium. The species'Expand

Ultracytochemical location of Na(+)/K(+)-atpase activity and effect of high salinity acclimation in gill and renal epithelia of the freshwater shrimp Macrobrachium olfersii (Crustacea, Decapoda).
Accumulation sites of lead phosphate reaction product consequent to Na(+)/K(+)-ATPase activity in gill and renal epithelia of the freshwater shrimp Macrobrachium olfersii were locatedExpand

Evolutionary transition to freshwater by ancestral marine palaemonids: evidence from osmoregulation in a tide pool shrimp
The transition from marine/brackish waters to freshwater habitats constitutes a severe osmotic and ionic challenge, and successful invasion has demanded the selection of morphological, physiological,Expand

The conquest of fresh water by the palaemonid shrimps: an evolutionary history scripted in the osmoregulatory epithelia of the gills and antennal glands
Extant Palaemonidae occupy aquatic environments that have generated physiological diversity during their evolutionary history. We analyze ultrastructural traits in gills and antennal glands ofExpand
