Radiotelemetry Of Heart Rates From Free-Ranging Gulls, J. W. Kanwisher, Timothy C. Williams , '64, J. M. Teal, K. O. Lawson Apr 1978

Radiotelemetry Of Heart Rates From Free-Ranging Gulls, J. W. Kanwisher, Timothy C. Williams , '64, J. M. Teal, K. O. Lawson

Biology Faculty Works

A lightweight radiotelemetry system with a range of 80 km was used to monitor heart rate from free-ranging Herring Gulls on flights of up to 20 km. Heart rate varied from 130 beats/min in a resting bird to 625 beats/min for sustained flight. Soaring birds showed rates similar to those of birds sitting quietly on the ground. Simultaneous records of telemetered heart rate and intraspecific conflict on the nesting island revealed that cardiac acceleration preceded overt visual communication. Intensely aggressive behavior was accompanied by heart rates approaching those of sustained flight. Heart rate as a measure of metabolic cost indicates …

The Behavior And Ecology Of Herotilapia Multispinosa (Teleostei, Cichlidae), Jeffrey R. Baylis Jan 1976

The Behavior And Ecology Of Herotilapia Multispinosa (Teleostei, Cichlidae), Jeffrey R. Baylis

Investigations of the Ichthyofauna of Nicaraguan Lakes

Because of their complex social behavior and the ease with which they can be manipulated, cichlid fishes have long been of special interest to the ethologist. However, most of the research into cichlid behavior has been on Old World species. The social behavior of New World species is different and deserves more study. This paper will describe the ethology of one of the Central American cichlids, Herotilapia multispinosa.
