Phenotypic flexibility in response to environmental salinity in the euryhaline crab Neohelice granulata from the mudflat and the saltmarsh of a SW coastal lagoon
(Springer, 2013-05)
This study constitutes a first attempt to investigate intraspecific differences in osmoregulatory capacity and digestive and metabolic responses at the biochemical level in relation to hyper- and hypo-regulation in a single ...
Differential modulation after feeding in different salinities and response to ABA and extracellular Ca++ of APN activity in hepatopancreas of the intertidal euryhaline crab Neohelice granulata
(National Research Council Canada-NRC Research Press, 2020-04)
Modulation of aminopeptidase N (APN) activity in the digestive tract by various factors would be important to adjust digestive and absorptive processes under different physiological and (or) environmental conditions. We ...
Dietary electrolyte balance affects growth performance, amylase activity and metabolic response in the meagre (Argyrosomus regius)
(Elsevier Science Inc, 2017-09)
Dietary ion content is known to alter the acid-base balance in freshwater fish. The current study investigated the metabolic impact of acid-base disturbances produced by differences in dietary electrolyte balance (DEB) in ...
Otolith Sr:Ca ratio and morphometry as indicators of habitat of a euryhaline species: the case of silverside Odontesthes bonariensisLa relación Sr:Ca y la morfometría del otolito como indicadores de hábitat de una especie eurihalina: El caso del pejerrey Odontesthes bonariensis
(Universidad Autónoma de Baja California. Instituto de Investigaciones Oceanológicas, 2015-07)
The silverside Odontesthes bonariensis is a euryhaline species native of South America and represents a very important fishing resource for the Plata Basin (Argentina and Uruguay). This study compares the Sr:Ca ratio of ...
Influence of reduced salinity on the histochemical fiber type composition of the claw closer muscle of two estuarine crab species, Cyrtograpsus angulatus and Neohelice granulata (Decapoda: Varunidae)Influencia de la salinidad reducida sobre la composición histoquímica de tipos de fibras del músculo de cierre de las quelas de dos especies de cangrejos estuariales, cyrtograpsus angulatus y neohelice granulata (Decapoda: Varunidae)
(Sociedad Chilena de Anatomía, 2017-06)
The estuarine crustaceans are exposed to frequent and abrupt environmental salinity changes that involve adjustments at different levels in muscle tissue. The histochemical composition of fiber types of the claw closer ...
Freshwater sharks and rays
(Cell Press, 2015-10)
Hang on, I thought sharks and rays only live in the ocean? That’s true for about 95%. However, there are species of elasmobranchs (sharks and rays) that occur regularly at low salinities, often beyond the tidal reaches of ...
Distribuição dos peixes nos estuários do nordeste brasileiro de acordo com a salinidade da água
(Universidade Federal do Rio de JaneiroBrasilMuseu NacionalPrograma de Pós-Graduação em Ciências Biológicas (Zoologia)UFRJ, 2017)
Two sodium pumps in the hepatopancreas of the intertidal euryhaline crab Neohelice granulata: Biochemical characteristics and differential modulation after feeding
(National Research Council Canada-NRC Research Press, 2018-01-05)
No study has been done on the existence, biochemical characteristics, and modulation of K+-independent ouabain-insensitive Na+ ATPase activity (the second sodium pump) in the digestive tract of intertidal euryhaline crabs ...
INTERANNUAL VARIABILITY IN TROPICAL ESTUARINE COPEPOD ASSEMBLAGES OFF NORTHEASTERN BRAZIL
(CRUSTACEAN SOC, 2011)
We studied copepod assemblage variability among years, seasons, and tidal states in the Mucuri River estuary (Bahia State, Brazil). Zooplankton samples were collected seasonally through five years (2002-2006) at three ...
