... conditions. The buoyancy optimisation of channel catfish relative to the flow conditions that they inhabit not only reflects differences in swimming behaviour but also provides new insights into the adaptation of physostome fish species to various freshwater environments. * Author for correspondence...

.... The ciliary reversal duration is correlated with the amount of Ca 2+ influx. Here, we evaluated the effects due to the activation or blockade of N -methyl- d -aspartic acid (NMDA) receptors on swimming behaviour in Paramecium . Paramecia normally swim forward, drawing almost linear tracks. We observed...

... dropped significantly during the first 2 h and kept decreasing significantly until the end of the trial at 18 h. These results support the hypothesis that ecological factors mould the swimming behaviour of hatchling sea turtles, with predator pressure being important in determining the strategy used...

...Heidi K. Grønlien; Anna Kari Rønnevig; Bjarne Hagen; Olav Sand SUMMARY The swimming behaviour of ciliates is mainly determined by membrane potential and transmembrane fluxes. In a chemical gradient, swimming ciliates may approach or move away from the source. Based on experiments on Paramecium...

...Itai Plaut ABSTRACT The zebrafish Danio rerio exhibits substantial morphological variability in the sizes and shapes of the body and the caudal fin. The present study describes swimming performance, swimming behaviour and routine locomotor activity patterns in three of the major morphotypes: wild...

... development swimming behaviour statolith biomineralization In this paper we demonstrate a correlation between levels of the element strontium (Sr) in sea water and embryonic development of statoliths. These mineralized aragonite structures lie within the statocyst organs, which control balance...
