Where have all the salamanders gone?

Biologist to discuss amphibians as environmental indicators

The diminishing populations of frogs and other amphibians across the United States will be the subject of Indiana University's 2002 James P. Holland Memorial Lecture, to be given by University of California-Berkeley biologist Tyrone B. Hayes. The event is free and open to the public.

Hayes' contributions to developmental endocrinology have impacted both environmental science and human health. His talk, "From 'Silent Spring' to 'Silent Night' ... The Impact of Modern Day Pesticides on Amphibians," will take place Monday (Oct. 7) at 4 p.m. CDT in Myers Hall, Room 130, on the Bloomington campus. Streaming audio of the lecture will be made available for listening later in the week at

The James P. Holland Memorial Lecture Series was created in 2000 by the Office of the Vice President for Student Development and Diversity, the Office of Multicultural Affairs, and the Department of Biology to recognize the scholarly excellence of minority life scientists. In addition to supporting the annual lecture series, the Department of Biology and the Office of Research and University Graduate School have established a graduate fellowship in Holland's honor to support the training of a first-year Ph.D. student from a demographic group under-represented in the life sciences.

James Holland was a devoted teacher and reproductive endocrinologist who helped advance scientists' understanding of how thyroid hormones influence reproductive physiology in women. He was awarded Indiana University's Distinguished Service Award in 1994. In 1997, Chancellor Kenneth Gros Louis created the Chancellor's Medallion and named Holland its first recipient.
