Effect of low salinity on the yellow clam Mesodesma mactroides.
The aim of this study was to determine the lethal salinity (LC50) for the yellow clam Mesodesma mactroides (Bivalvia: Mesodesmatidae) and identify histopathological alterations that could be used to diagnose structural changes in clam tissue. Clams in two size classes (adults and juveniles) were placed in 10 L chambers and exposed to salinities of 35, 30, 25, 20, 15, 10, and 5 g/L. There were t...
متن کاملPopulation dynamics of the yellow clam Mesodesma mactroides: recruitment variability, density-dependence and stochastic processes
Recruitment of benthic marine invertebrates varies greatly at different spatio–temporal scales. For instance, population dynamics of the yellow clam Mesodesma mactroides at Uruguay exhibit large temporal fluctuations, mainly associated with recruitment. We used data from an 8 yr long-term study to develop an age-structured model to show that density-dependent and densityindependent forces actin...
متن کاملIndia ink induces apoptosis in the yellow clam Mesodesma mactroides (Deshayes, 1854). Optical and ultrastructural study.
This paper reports on the acute inflammatory and cellular process in the yellow clam, Mesodesma mactroides, induced by injection of India ink into the muscular foot. Histological observations with optical and electronic microscopy were made at 24 and 48 h after injection. The induced cellular inflammatory response consisted of a general hemocyte infiltration without necrosis and apoptotic activ...
متن کاملWinter Distribution, Density and Size of Mesodesma Mactroides (bivalvia, Mactracea) in Monte Hermoso Beach (argentina)
The yellow clam Mesodesma mactroides (Deshayes, 1854) is a seasonal migrant that moves in spring to the sandy upper intertidal level. In this paper we analyze the spatial distribution of density and mean shell size of the yellow clam population in Monte Hermoso beach (Argentina) in winter 1995, i.e., three months before the mass mortality occurred in November 1995. Sampling covered 32 km of bea...
متن کاملEmbrionary and larval development of the marine clam Tivela mactroides (Bivalvia: Veneridae) in Zulia State, Venezuela.
The marine clam, Tivela mactroides, from Caño Sagua beach, Venezuela, was spawned and reared under laboratory conditions to monitor its early development. Spawning was spontaneous but in some cases it had to be induced by the additon of eggs and sperm. After fertilization, the embryonic development occurred at 5 hr approximately. Trochophore larvae were observed between eight and ten hours late...
