Effects of salinity on larval stages of the rhizocephalan barnacle Loxothylacus texanus: survival and metamorphosis in response to the host, Callinectes sapidus
It is known that the rhizocephalan barnacle Loxothylacus texanus infects the greater blue crab, Callinectes sapidus, in the Gulf of Mexico and adjacent waters, however, factors that affect the prevalence and distribution of this parasite, particularly the dispersive larval stages of this organism, are not well understood. In the current study, the effects of salinity on larval survival and the ...
متن کاملMercury transport and bioaccumulation in riverbank communities of the Alvarado Lagoon System, Veracruz State, Mexico.
The Alvarado Lagoon System (ALS) is located within the Papaloapan River Basin in southern Veracruz, Mexico. The ALS is a shallow system (2 m) connected to the Gulf of Mexico through a narrow sea channel. There are a large number of riverbank communities within the ALS that are dependent upon its biological productivity for comestible and economic subsistence. The purpose of this project was to ...
متن کاملMolecular indicators of hypoxia in the blue crab Callinectes sapidus
Occurrence of hypoxia in estuarine waters is increasing, and recovery of impacted estuaries is slow. Detection of early effects of hypoxia is needed for timely remedial action to be taken. Here we examine the use of hypoxia-responsive gene and protein expression profiles in the blue crab Callinectes sapidus as early indicators of impacts of hypoxia. We cloned 23 potential hypoxiaresponsive gene...
متن کاملConcentration of rotavirus and enteroviruses from blue crabs (Callinectes sapidus).
A simple method for concentration and detection of rotavirus and enteroviruses in the blue crab is described. Virus was separated from tissue homogenates at pH 9.5, concentrated by adsorption to protein precipitates at pH 3.5, and recovered by elution of precipitates at pH 9.2. Test samples of 12 to 15 ml were produced from an initial 100 g of crab tissues. Cat-floc precipitation was used to re...
متن کاملSexual Competition Among Male Blue Crab, Callinectes sapidus.
Experiments and field data on blue crab, Callinectes sapidus, from mid-Chesapeake Bay between 1991 and 1994 were used to test whether large males have advantages over small males in accessing females and in sperm competition. In the field, large males were paired more often, especially with large, more fecund females. However, the variance in the relationship between male and female size in mat...
