Diel vertical migration of a pelagic amphipod in the absence of fish predation
Blinn DW, Grossnickle NE, Dehdashti B. 1988. Diel vertical migration of a pelagic amphipod in the absence of fish predation. Hydrobiologia: The International Journal on Limnology and Marine Sciences. 160(2):165-171
The pelagic amphipod, Hyalella montezuma, migrates vertically into the surface waters at twilight in Montezuma Well, Arizona, USA despite the absence of fish predators or thermal stratification. We suggest that a persistent, dense, neustonic algal assemblage may provide a food resource incentive for the twilight ascent.
