Mechanical properties of the cement of the stalked barnacle Dosima fascicularis (Cirripedia, Crustacea)
The stalked barnacle Dosima fascicularis secretes foam-like cement, the amount of which usually exceeds that produced by other barnacles. When Dosima settles on small objects, this adhesive is additionally used as a float which gives buoyancy to the animal. The dual use of the cement by D. fascicularis requires mechanical properties different from those of other barnacle species. In the float, ...
متن کاملCharacterization of cement float buoyancy in the stalked barnacle Dosima fascicularis (Crustacea, Cirripedia)
Dosima fascicularis is the only barnacle which can drift autonomously at the water surface with a foam-like cement float. The cement secreted by the animal contains numerous gas-filled cells of different size. When several individuals share one float, their size and not their number is crucial for the production of both volume and mass of the float. The gas content within the cells of the foam ...
متن کاملRadiation effects of tritiated seawater on development of the goose barnacle, Pollicipes polymerus.
Barnacle embryos were reared in Millipore cytology monitors containing approximate tritiated water (HTO) concentrations of background plus 0, 10, 10, 10, 10, 10, and 10 μCi/ml. After 32 days the cultures were fixed and the numbers of larvae counted. A “molting index,” the percentage of larvae that molted at least once, was used to evaluate the effects of HTO on normal development. Effects were ...
متن کاملCharacterization of microsatellite loci and repeat density in the gooseneck barnacle, Pollicipes elegans, using next generation sequencing.
Pollicipes elegans is a commercially important and biogeographically significant rocky-shore gooseneck barnacle found along the eastern Pacific coasts of Peru, El Salvador, and Mexico. Little is known about its reproductive biology, and no genetic resources exist despite its growing importance as a fisheries species in the region. Next generation sequencing methods can provide rapid and cost-ef...
متن کاملSeasonal variation of metal contamination in the barnacles Pollicipes pollicipes in northwest coast of Portugal show clear correlation with levels in the surrounding water.
The concentrations of metals were determined in northwest (NW) coast of Portugal seawaters and soft tissues of goose barnacles Pollicipes pollicipes. P. pollicipes can be used for monitoring metal contamination in these coastal seawaters, because there were significant correlations (p<0.05) for all metals between soft tissues and seawaters during the four seasons. Metal concentrations in seawat...
