What Does the Distribution of Stygobiotic Copepoda (Crustacea) Tell Us About Their Age?
David C. Culver & Tanja Pipan - (36/1,2007)
Geographic distribution of stygobionts is often used to estimate
age of a group by assuming vicariant speciation with little or no
subsequent dispersal. We investigated the utility of using distributional
data for Slovenian stygobiotic copepods by assuming
that dispersal is a way to measure age of a species. We list some
species of Copepoda that, on the basis of their range and frequency
of occupancy within their range, should be older. Body
size is not predictor either of range or frequency of occupancy.
