The relationship between organisms and contaminants may be a two-way interaction: contaminants affecting the biota and the biota affecting the environmental fate and distribution of the contaminants. This may be especially so for sediment-dwelling organisms, because their burrowing and feeding can drastically influence sediment characteristics.

Climate change is producing sea level rise and deoxygenation of the ocean, altering estuaries and coastal areas. Changes in oxygen availability are expected to have consequences on the physiological fitness of intertidal species. In this work we analyze the coping response of the intertidal stout razor clam (Tagelus plebeius (Lightfoot, 1786)) to ...

The Biology of the Stout Razor Clam Tagelus plebeius: II. Some Aspects of the Population Dynamics
Chesapeake Science, 1977The population dynamics of the stout razor clam,Tagelus plebeius, were investigated for three years. Density, year-class structure, and recruitment varied with elevation above mean low water, among sample areas, and among years. Recruitment was unimodel and restricted to the late spring.

[Water quality of closed polyculture of penaeid shrimp with tilapia and constricted tagelus].
Ying yong sheng tai xue bao = The journal of applied ecology, 2001A variety of water quality parameters were monitored in enclosures for the polyculture of penaeid shrimp with tilapia and constricted tagelus. The result showed that the environment of the polyculture systems was better than that of monoculture one. The fluctuation of DO in the water of polyculture enclosures was less violent, and their lowest values ...

Six intertidal populations ofTagelus plebeius, the stout razor clam, and associated macroinvertebrates were sampled in the North Inlet estuary, near Georgetown, South Carolina.T. plebeius inhabited only stable sediments composed of greater than 2.0 % silts and clays and which were covered by a visible surface film of benthic microalgae.

Production of a Population of the Stout Razor Clam (Tagelus plebeius Solander) in a Virginia Estuary
1979The annual net secondary production of the stout razor clam, Tagelous plebeius, was estimated at three sites on an intertidal sand flat at Lynnhaven Inlet, Virginia. Samples were taken at six week intervals for one year. The range of net production (P), mean annual biomass (B), and P/B ratios was 18.3-28.7 g m-2year-1, 27.2-53.3 g m-2, and 0.54-0.67 ...

Shellfish harvesting in intertidal areas is a widespread and economically important activity in many countries across West Africa. However, in some areas, there is virtually no information concerning the levels of contaminants (and other elements related to nutritional aspects) in the harvested species. We collected sediments and several individuals of

Comparative Biochemistry and Physiology Part A: Physiology, 1979
Abstract 1. 1. The exponent ( b ) relating metabolic rate to dry weight in excised gills of Tagelus plebeius is not maintained constant throughout the seasons or upon acute exposure to temperatures of 9–34°C. 2. 2. Acclimation (11–29°C) and test (9–34°C) temperatures have a significant effect (α = 0.01) on the mean rate of oxygen uptake by ...
