The brine shrimp Artemia exhibits two reproductive modes: 1) oviparity, producing diapause embryos; and 2) ovoviviparity, producing free-swimming nauplii. Previous studies have suggested the existence of a critical stage that determines the reproduct

Tachykinins (TKs) are a family of neurotransmitters that function as signaling molecules for such processes as maintaining homeostasis, regulating stress response, and modulating pain. TKs require the expression of at least one of three receptor subt

Artemia nauplii are important bait or food sources in aquaculture, but the egg shells after incubation are always subjected to discarding as natural wastes; therefore, application and utilization of the Artemia egg-shell wastes will be an important i

The possible presence of egg predators in brood masses of portunid crabs from Pacific Central America has not been studied yet. This survey reports the finding of a nemertean crab egg predator on the portunid crab, Callinectes arcuatus, from the Golf

Of the 14 nominal species that are now or have ever been assigned to the genus Paranemertes Coe, 1901 , four have been reported to have stylets with a spirally fluted or braided appearance. Although differentiation in color patterns has been document

Nemerteans experience varying environmental temperatures during low tide exposures. Inducible heat shock proteins (hsps) have been reported for most organisms following both artificial heat stress and natural environmental temperature variations. Thi

Ecdysteroids are a class of steroidal hormones thatare important in molting and reproduction inarthropods. These hormones have been recentlydetected in non-arthropodan groups, such assoft-bodied worms. To continue our efforts todetermine the presence

Summary Ecdysteroids in non-reproductive, reproductive, and post-reproductive specimens of two nemerteans, Paranemertes peregrina and Pantinonemertes californiensis, were studied using radioimmunoassay (RIA). Ecdysteroid concentrations increased duri
