Evolutionary Biology

It is with pleasure that the editors dedicate this volume to William Camp- bell Steere, one of the founding editors of Evolutionary Biology. As Dr. Steere approaches his eightieth birthday we include in the volume a brief biography and a complete bibliography of his publications in celebration of his contributions to the biological sciences.
