Randall William Davis Biography

Randall William Davis is one of the most popular and richest Physiologist who was born on May 10, 1952 in Los Angeles, California, United States. Randall Davis, the oldest child of Charles Davis and Beverly Sheldon, was born in Los Angeles. He and Beverly Sheldon met and were married there after the Second World War. His father was originally from Iola in Kansas and his mother was born in Los Angeles. At five years old, Davis moved to San Gabriel Valley from Los Angeles. He became interested in diving and marine biology as a child. At age 15, he kept marine aquaria and collected his own invertebrates and vertebrates. He also obtained his SCUBA certification. In 1970, he was named Salutatorian of his Nogales High School graduating class and was inducted into California Scholarship Federation. Davis was a pre-medical student at the University of California at Riverside. He spent his third year at the University of St. Andrews, Scotland in the Department of Physiology as part of the UC Education abroad Program. He developed a keen interest in physiology there, but he also spent time traveling across Europe, where he had cultural experiences that inspired him to study art history and comparative literature. In 1974, he graduated from the University of California with his Bachelor of Science degree in Biology. He was also inducted into the Phi Beta Kappa Honor Society for his interest in the Liberal Arts. In 1974, Davis married Ana Maria Melgoza. The couple returned to St. Andrews to continue their studies in the Department of Physiology. Davis was admitted to the Physiology and Pharmacology Doctoral program in the School of Medicine, University of California San Diego after a year.

Davis was part of the 1977 Weddell seal research in McMurdo sound, Antarctica. This led to the creation of an aerobic dive limit (ADL), and revolutionized the field of marine mammal physiology. Davis was a Scripps doctoral student for five years. He studied the intermediate metabolism of harbor seals under forced submersion using isotopic tracer and was the first to apply this technique to marine mammals. Per Scholander was his comparative physiologist and he interacted with him. Scholander established the Physiological Research Laboratory at Scripps late in 1950s.

In addition to the effects of oil on sea otters, Davis has studied the behavioral ecology of sea otters in Prince William Sound, Alaska since 2001. This long-term study has included foraging behavior and prey preference, foraging mechanics, female and pup activity and energy budgets, male activity budgets and territoriality, habitat-associations, and non-invasive methods to identify individual sea otters for which he received the Christine Stevens Wildlife Award in 2008. Davis has conducted additional studies on the movements, behavior and habitat associations of cetaceans in the Gulf of Mexico, sperm whales in the Gulf of California and New Zealand, Heaviside’s dolphins off the coast of South Africa, northern elephant seals in California, southern elephant seals in Argentina, and spotted seals in Alaska. He has also conducted research on the diving behavior, energetics and maternal strategies of fur seals, sea lions and penguins and locomotion and thermoregulation in whale sharks.

A third area of Davis’ research has focused on the thermoregulatory physiology of sea otters and the harmful effects of oil exposure. In the 1980s, Davis and his colleague Dr. Terrie Williams conducted research for the U.S, Department of the Interior that developed techniques to mitigate the effects of oil on sea otters and other fur bearing marine mammals. In the 1980s, the primary concern of the U.S. Department of the Interior had been the potential devastation of the small California sea otter population by an oil tanker spill. However, it was during the 1989 Exxon Valdez oil spill in Prince William Sound, Alaska that their science-based techniques to clean and rehabilitate otters were first used when Davis was asked by the U.S, Department of the Interior to direct the Sea Otter Rehabilitation Program. This effort, involving over 300 people, rehabilitated and released 225 oiled sea otters, the largest number ever held in captivity. Davis then co-authored a book on the methods for rehabilitating oiled sea otters, and this is still the standard among rehabilitation programs for fur bearing marine mammals. This book and other information on sea otters is available to the public online: www.wildliferesearch.com.

John B. West was his first graduate advisor. Dr. John B. West, the high altitude respiratory physiologist. Davis did an internship with Dr. Gerald Kooyman in 1976. Kooyman was a comparative biologist at Scripps Institution of Oceanography. Kooyman was a researcher on the diving physiology and behavior of harbor seals. He had just developed the first animal-borne, time-depth recorders (TDRs), to study the diving behavior free-ranging marine mammals. Davis became Kooyman’s doctoral student in 1976 after deciding to study the physiology marine mammals. That summer, he attached TDRs to northern furs seals on the Pribilof islands in the Bering sea. He then sailed aboard the National Science Foundation’s research vessel Hero in the Southern Ocean to study Antarctic fur seal diving behavior. In 1979, he returned to South Georgia Island and installed the first microprocessor-based dive recorders for King Penguins. The results were published in Science.

Randall William Davis, born 10 May 1952 in Los Angeles (California), is an educator and researcher who studies physiology and behavior ecology of marine mammals and other aquatic vertebrates. His physiological research is focused on adaptations of marine mammals to deep, long diving. Davis has always stressed the importance of studying aquatic animals within their natural environments. He has spent many years creating animal-borne instruments that capture video and monitor swimming performance, three-dimensional movements and other environmental variables in order to better understand their ecology and behavior. Through his academic pursuits and 94 research expeditions, he has been to 64 countries and territories across seven continents as well as all of the oceans.

Davis was part of the initial deployments, in the mid-to late 1970s, of microprocessor and mechanical time-depth recorders (TDRs), on penguins and pinnipeds. In the 1980s, more advanced microprocessor-based and satellite- monitored tags were introduced. By 1986, many species of marine mammals, penguins, and reptiles had recorded thousands of dives. Time-depth profiles didn’t provide any information about the behavior of the animals at depth so behavioral interpretations were only speculation. Davis partnered with William Hagey, an electronics engineer, to develop instruments that could record video, depth, swim speed and magnetic bearing. They also recorded pitch and roll, flipper/fluke movement, GPS location at surface, and environmental variables like conductivity (salinity), temperatures and dissolved oxygen. In 1987, a Sony camcorder was mounted in a plastic case and used to deploy the first instrument on a Weddell seal. It was simple, but it showed that animal- borne video recording and data recorders can be a new way to study marine animals. The camera was mounted on the head and recorded prey movements. These can be correlated to swim speed, flipper stroking, body orientation, and three-dimensional movements. Davis and Hagey developed five generations of data and video recorders over the past 30 years that were used on sharks, seals, sea turtles, and whales. Each generation had smaller sensors, more sensors, and was able to record video and data for longer periods of times. These instruments allow researchers to classify and differentiate the behavioral functions of divers and provide detailed descriptions of hunting strategies and foraging strategies. This is Davis’ main focus.

In 1980, Davis graduated with a Doctoral Degree in Physiology and immediately departed for Antarctica where he, his wife Ana Maria, and two colleagues spent a year (including the austral winter) in a remote field camp at White Island studying the diving behavior of Weddell seals. For his effort, Davis received an Antarctica Service Medal with Winter Ribbon and a U.S. Geological Service Antarctic Site Designation 18773 (Davis Bluff; 79°09’ S, 167°35’ E) on White Island and was inducted into the Explorers Club. Upon returning to Scripps, he received a National Institutes of Health Post-Doctoral Fellowship where he continued his research on harbor seal metabolism during submerged swimming In 1983, he became a Research Scientist at the Hubbs-SeaWorld Research Institute in San Diego under the direction of Dr. William Evans. While at Hubbs, Davis and his colleagues studied the thermoregulatory effects of oil on sea otters and developed methods to mitigate the harmful impacts. In March 1989, he was asked by the U.S. Department of the Interior to direct an Oiled Sea Otter Rehabilitation Program following the Exxon Valdez oil spill in Prince William Sound, Alaska. This program rehabilitated 225 oiled sea otters and became the basis for a book that Davis co-authored on methods for rehabilitating oiled sea otters and other fur-bearing mammals.
