The Water and Electrolyte Exchange of Nereis Diversicolor (muller)
IT has been shown by McCutcheon & Lucke (1928) that in glucose solutions isotonic with 40 per cent sea water, the eggs of the sea-urchin Arbada absorb twice as much water as they do from 40 per cent sea water, and that this increased imbibition is prevented by a small concentration of calcium ion in the glucose solution, even in the absence of the other cations of sea water. Pantin (1931a) show...
متن کاملThe Effects of Phthalates on Nereis diversicolor
Animals are exposed, in the natural environment, to a range of human activity related dissolved chemicals that are potentially impacting on their fitness. The animals responses to such stress determines its fitness, physiology and in case of chemical signals also its behaviour. If physical or chemical changes in the ecosystem make the detection of such a chemical impossible, then it can be reas...
متن کاملHypo-osmotic urine in Nereis diversicolor.
Although Beadle a9 early as 1937 suggested that the urine of Nereis diversicolor O. F. Miiller might be of lower concentration than the body fluids when this worm is hyperregulating in low salinities, there has been no direct measurement of urine concentration to support this reasonable idea. Jorgensen & Dales (1957) studied osmotic water uptake and loss in N. diversicolor and calculated that t...
متن کامل(Corophium vol utator, Macoma balthica, Nereis diversicolor)
Acute toxicity of hexavalent chromium to 3 estuarine ammals (Corophium volutator, Macoma balthica, Nereis diversicolor) has been studied at 3 temperatures (5, 10, 15 'C) and a range of salinities (5 to 40 %o, in 5 %O increments), at time intervals of up to 384 h. Toxicity increased as temperature increased and as salinity decreased. From an analysis of variance, the significant factors and thei...
متن کاملSmelling Danger – Alarm Cue Responses in the Polychaete Nereis (Hediste) diversicolor (Müller, 1776) to Potential Fish Predation
The harbour ragworm, Nereis (Hediste) diversicolor is a common intertidal marine polychaete that lives in burrows from which it has to partially emerge in order to forage. In doing so, it is exposed to a variety of predators. One way in which predation risk can be minimised is through chemical detection from within the relative safety of the burrows. Using CCTV and motion capture software, we s...
