Cyprinella: degree of similarity in sister species. J. Fish Biol. 74(1), p
120-132.
Abstract: Signal structure and behavioural context were examined in two
sister species, the Tallapoosa shiner Cyprinella gibbsi and the tricolor
shiner Cyprinella trichroistia, with two more distantly related species, the
Ocmulgee shiner Cyprinella callisema and the whitetail shiner Cyprinella
galactura, in order to test the hypothesis that more closely related species
would share components of signals not shared with more distant relatives,
and to look at the degree of divergence. The species examined differed in
number and type of signal components, contexts and frequency under which
calls were produced. While all species produced pulses arranged into pulse
bursts, C. gibbsi and C. trichroistia shared unique call types, chirps and
rattles, and C. galactura and C. callisema both produced the knock call
type. The sister species shared more components of their call repertoire
with each other than with the more distantly related C. galactura and C.
callisema and clustered together based on courtship call similarity.
