ISSN: 1432-1793Source: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract The upper lethal tolerances of Tellina tenuis da Costa and T. fabula Gmelin were studied under a variety of temperature regimes in which both short-term and long-term mortality were noted; these included steady temperatures, acclimation at a steady temperature then exposure to a steady tempeature, and acclimation at gradually increasing temperatures. T. tenuis alone was also tested for variation in mortality rate according to the date of collection or to the size (i.e., age) of the mollusc. The results suggested that T. tenuis was consistently more tolerant than T. fabula, and that the difference in tolerance was around 5 C°. Both species readily acclimated to higher temperatures after steady temperature acclimation, but not under a regime of gradually increasing temperature. There was no significant, variation in the mortality rate of T. tenuis with season or age. It is suggested that, since the difference in temperature tolerance is not reflected in their respective geographical distributions, there may be some other stage in their life cycle, e.g. the larvae, which is equally susceptible to temperature extremes. The difference in tolerance is, however, reflected in their respective littoral and sublittoral distributions.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-1793Source: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract The dispersion of Tellina tenuis da Costa in the laboratory was analysed by the Clark and Evans nearest-neighbour test and by the Kolmogorov-Smirnov one-sample test. The dispersion was random, with a slight tendency toward aggregation that was independent of density. In the field, the dispersion was analysed by the Clark and Evans nearest-neighbour test and by the X2 approximation to Fisher's coefficient of dispersion. The dispersion was again random, this time with a slight tendency toward spacing out that was independent of density. The tendency toward aggregation displayed in the laboratory was independent of the dispersion pattern shown at the start of the experiment, and also unaffected by the edge of the container. The apparent randomness suggests that T. tenuis is primarily a suspension feeder, but may be a deposit feeder under certain environmental conditions.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-5125Keywords: nutrient concentrations ; interdidal sediments ; pore waters ; spatial variability ; IrelandSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract Spatial variability in nutrient concentrations in the intertidal sediments and pore waters has been studied along downshore transects and in core profiles at three locations in the Shannon estuary on the west coast of Ireland. The parameters measured were N, as Kjeldahl N, NO3, NO2, and NH3, and P as total P and PO4 along with a range of other environmental variables such as salinity and sediment organic content. The concentrations of all nutrients varied with season, but winter values were generally low in comparison with polluted mainland european estuaries. There was a great deal of variation in nutrient concentrations along the transects, and coefficients of variability of up to 153% (NH3), 173% (NO3), 129% (NO2) and 117% (PO4) were found. Overall, there was little evidence of any trends in concentration in any of the nutrients from the top to the bottom of the transects, although it was occasionally possible to link particular instances to local conditions such as the presence of the channel or a stream. Sediment core profiles showed typical patterns, with NO3 concentrations for example being highest in surface sediments, while NH3 and PO4 concentrations increased with depth. Rather surprisingly perhaps, NO3 could still be detected on occasion at depths of up to 20 cm, well below the Redox Potential Discontinuity (RPD) and the limit of oxygen penetration which oxygen microelectrodes had measured as being within a few mm of the surface. This was ascribed to the activities of the macrofauna, in that the oxidised sediment which lined the burrows could clearly be seen in some cores. This study not only shows that nutrient distributions along estuarine gradients are linked to physicochemical factors such as oxygenation and freshwater/marine influence, but also that sediment instability, through random physical events such as storms, and macrofaunal activity play an important role and that these latter factors deserve closer attention.Type of Medium: Electronic ResourceURL: -
20Problems in the assessment of heavy-metal levels in estuaries and the formation of a pollution indexStaff View
ISSN: 1438-3888Source: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract Most estuaries receive a high heavy-metal input from industries. This is reflected in the relatively high levels found in numerous estuarine organisms and in sediments. Many indicators have been suggested for facilitating the detection of heavy-metal pollution, but the problems in using these indicators to evaluate the metal loading of estuaries are considerable. Variations in species composition, and conditions at different sites, differences in season of sampling, and age of organism, as well as different metal levels in different parts of the organism, make the interpretation of results difficult. The levels reported here, similar to those in other unpolluted estuaries, have been used to suggest a baseline concentration for heavy metals in estuaries. The concept of a baseline is fundamental to the formation of a “Biological Quality Index” and “Pollution Load Index,” and a formula for such an index is suggested and tested at a preliminary level against published data for an English and a European estuary.Type of Medium: Electronic ResourceURL:
