Eric Pianka
Eric Rodger Pianka is an American herpetologist and evolutionary ecologist.
Early life
Pianka was born in Siskiyou County in 1939. At age 13, he was seriously injured in a bazooka blast in the front yard of his childhood home in Yreka, California. His left leg became gangrenous, and he lost 10 cm of his tibia, as well as the terminal digit of the middle finger on his right hand. Pianka's childhood injury left him with a short and partially paralyzed leg. In later life, his short leg resulted in spinal scoliosis and cervical spondylosis.Pianka graduated from Carleton College and earned his Ph.D. from the University of Washington in 1965. He went on to do postdoctoral work with ecologist Robert MacArthur at Princeton University. This period, during which he worked closely with the temporarily studentless MacArthur, had a major influence on Pianka's thinking. In 1966, with MacArthur, Pianka coauthored the paper, "On optimal use of a patchy environment". Pianka frequently mentions MacArthur in his lectures and keeps a webpage for his deceased mentor and colleague. In some ways, Pianka's own research program expands upon and continues the work that he and MacArthur began.
Career
Since 1968, Pianka has been on the faculty of the University of Texas at Austin. His research centers on empirical and theoretical components of natural history, systematics, community and landscape ecology.Pianka has performed extensive ecological investigations on vertebrate communities in three desert systems on three continents: the Great Basin, Mojave, and Sonora Deserts in North America; the Kalahari in Africa; and the Great Victoria desert in Western Australia. His monographic treatment of this work is a landmark ecological synthesis.
Pianka's current work focuses on lizard communities in Australia. His research projects include study of the phylogeny and ecology of a number of groups of Australian lizards and an extensive study of the unique biotic landscape produced by Australian brush fires. His favorite lizard is a small Australian goanna, Varanus eremius. In his research, Pianka combines traditional field biological methods with recent technological innovations in statistical analysis, phylogenetic reconstruction, and imaging of the Earth's surface in attempts to answer major questions about evolution and ecology.
Pianka has trained other scientists and twelve of his former graduate students are professors at major universities, including Kirk Winemiller, a professor at Texas A&M University, and Raymond Huey, a professor at the University of Washington. Additionally, he teaches a range of popular undergraduate courses; he received an award for excellence in teaching from UT Austin in 1999.
Texas Academy of Science speech
Pianka's acceptance speech for the 2006 Distinguished Texas Scientist Award from the Texas Academy of Science resulted in a controversy in the popular press when Forrest Mims, vice-chair of the Academy's section on environmental science, claimed in the Society for Amateur Scientists e-journal The Citizen Scientist that Pianka had "endorsed the elimination of 95 percent of the human population" through a disease such as an airborne strain of the Ebola virus. Mims claimed that Pianka said the Earth would not survive unless its population was reduced by 95%, suggesting that the planet would be "better off" if the human population were reduced and that a mutant strain of Ebola would be the most efficient means. Mims' affiliate at the Discovery Institute, William Dembski, then informed the Department of Homeland Security that Pianka's speech may have been intended to foment bioterrorism. This resulted in the Federal Bureau of Investigation interviewing Pianka in Austin.Pianka has stated that Mims took his statements out of context and that he was simply describing what would happen from biological principles alone if present human population trends continue, and that he was not in any way advocating for it to happen. The Texas Academy, which hosted the speech, released a statement asserting that "Many of Dr. Pianka's statements have been severely misconstrued and sensationalized." However, Kenneth Summy, an Academy member who observed the speech, wrote a letter of support for Mims' account, saying "Dr. Pianka chose to deliver an inflammatory message in his keynote address, so he should not be surprised to be the recipient of a lot of criticism from TAS membership. Forrest Mims did not misrepresent anything regarding the presentation."
Pianka appeared on NBC-affiliate KXAN Austin and on two cable talk-show and posted a statement on his University of Texas website that said in part:
As a consequence of the controversy, Pianka and members of the Texas Academy of Science received death threats. According to Pianka, his daughters were worried about his and their safety, and his life had been "turned upside-down by 'right-wing fools'."
Awards and accolades
Pianka was a 1978 Guggenheim Fellow, a 1981 American Association for the Advancement of Science Fellow, and a 1990 Fulbright Senior Research Scholar. He has received numerous awards, and at least three species, an Australian lizard and two lizard parasites, are named after him. A symposium in his honor was held by the Herpetologist's League in 2004. The American Society of Ichthyologists and Herpetologists passed a resolution on the word "Piankafication" to describe Pianka's influence on evolutionary biology and ecology at their business meeting in 2004. In this resolution, they noted that he has had "vast and immeasurable influence on several fields of evolutionary ecology" and that his "years in the field have set the standard for both natural history and for ecological studies, resulting in publications that have lain the foundation for research programs..."Pianka received the 2006 Distinguished Texas Scientist Award from the Texas Academy of Science. He and his research were featured in a wildlife documentary on monitor lizards — "Lizard Kings" — which premiered nationally on the PBS NOVA series in October 2009.
In 2015, Pianka was awarded the Auffenberg Medal in recognition of his extensive research on monitor lizards by the Monitor Lizard Specialist Group. In the same year, he received the highest award of the Ecological Society of America, the Eminent Ecologist Award.
Works
Pianka has produced about 200 scientific papers, as well as the textbook, Evolutionary Ecology, which has gone through seven editions and has been translated into five languages. In 2003, he also published Lizards: Windows to the Evolution of Diversity, coauthored with longtime collaborator Laurie Vitt, won the Grand Prize at the Robert W. Hamilton Faculty Author Award at The University of Texas at Austin as well as the Oklahoma Book Award from the Oklahoma Center for the Book.Selected bibliography
