P. D. Karns is credited as one of the authors of Ecological Studies of the Timber Wolf in Northeastern Minnesota, a detailed research work produced with L. David Mech, Louis Daniel Frenzel, Robert R. Ream, and John W. Winship.
The book is closely tied to field studies of wolves in northeastern Minnesota and reflects the practical, observation-based style of wildlife biology. From the sources available here, Karns appears in print mainly through this collaborative scientific work rather than through a large solo bibliography.
Reliable biographical details about Karns’s life beyond that publication were limited in the sources I could confirm, so this overview focuses on the documented record of authorship and the author’s connection to wildlife research.
