The intermittency of a point process is the extent to which the number of events in a time window has pronounced … departures from typical values. Combining point process and multifractal formalisms indicates that the correlation codimension … can be used to quantify intermittency. The correlation codimension is easily estimated and is simply related to other …

percentage of saturation and pH data show remarkably nice scaling ranges, indicating an important coupling with turbulence, but … reveal the possible influence of environmental factors such as tides and turbulence. Turbidity variability is highly complex … and does not appear to be directly coupled to turbulence, since no clear range is visible. On the other hand, oxygen …

We consider symbolic sequences of copepod behavior, classified as “break” and “slow swimming” states. Successive residence times for each state have been recorded for 327 symbolic times series obtained from 52 different trajectories. We performed a symbolic dynamics analysis of the...

The two-dimensional motion behaviour of the common intertidal gastropod Littorina littorea is investigated as a function of the immersion time from three sampling sites on an exposed rocky shore. A total of 90 individuals have been individually marked and tracked over 14 consecutive daylight low...
