Mel Sunquist is a professor in the Department of Wildlife and Ecology at the University of Florida. At the time of the publication of Wild Cats of the World (2002) he is stated as being an associate professor (1995-2003). His work is split between 40% research and 60% teaching. His area of research is ecology, behavior and conservation of mammalian carnivores. He has been widely published including 3 books. Wild Cats of the World is a superb book published by The University of Chicago Press, ISBN-13: 978-0-226-77999-7. I use it constantly.
Fiona Sunquist is less public. It is very hard to find information on her. At the time of writing I don’t know if she is a relative of Mel or his wife. Fiona Sunquist is a science writer and photographer. At 2002, she had been a roving editor for International Wildlife Magazine. With Mel they are the authors of Florida: The Ecotravellers’ Wildlife Guide and Tiger Moon.
I don’t have a photo of Fiona Sunquist.
