S OF PAPERS Twentieth Annual Albert L. Tester Memorial Symposium, 27-28 April 1995 1 The Albert L. Tester Memorial Symposium is held in honor of Professor Albert L. Tester, who, at the time of his death in 1974, was senior professor of zoology at the University of Hawai'i at Manoa. The faculty and students of the Department of Zoology proposed an annual symposium of student research papers as a means of honoring, in a continuing and active way, Dr. Tester's lively encouragement of student research in a broad range of fields in biology. Papers reporting original research in any aspect of biology solicited from graduate students at the university are presented at the spring-semester symposium. Income from contributions to the Albert L. Tester Memorial Fund of the University of Hawai'i Foundation provides two prizes for the best papers. Judges include representatives of the Department of Zoology faculty, winners from the preceding symposium, and a distinguished scholar from another university who also presents a major symposium address. This year Mimi A. R. Koehl, Professor of Integrative Biology, University of California at Berkeley, participated in the symposium.
