Samuel Joseph McNaughton passed away peacefully at his home in Syracuse, NY on January 18, 2024. He is survived by Margaret McNaughton, his wife of 64 years, his two children, Sean (daughter-in-law Catherine) and Erin, and six grandchildren, Martine, Joshua, Shelby, Eli, Grace, and Esther.
Sam was born in Takoma Park, Md, but, in his own words, “fished, trapped, and hunted his way through much of his childhood in northwest Missouri.” After falling in love in high school, Sam and Margaret together attended Northwest Missouri State University (NWMSU), where Sam planned to study agriculture to continue the family business of farming. But while at NWMSU, he enrolled in a plant ecology course taught by Dr. Irene Mueller (a J. E. Weaver student) who helped Sam understand the patterns that had piqued his interest during his romps through nature. As part of the course, students read and critically discussed primary literature, which may have been Sam's initiation to curiosity-driven scientific investigation. This one course was ground-shifting for Sam, causing a pivot from agriculture to an interest in studying ecology, and probably instilled in him a deep appreciation for the importance of teaching, which he would carry throughout his academic career.
After graduating, Sam decided to work with Calvin McMillan at the University of Texas, Austin, which had one of the only climate-controlled plant growth facilities available at the time. He earned his Ph.D. in 1964 at the precocious age of 25, after which he spent 1 year as an Assistant Professor at Portland State University and 1 year as a postdoc at Stanford University, before starting his 38-year-long academic post at Syracuse University (SU) in 1966.
Sam's early scholarly work spanning his Ph.D. through the mid-1970s at SU focused on plant ecotypic variation, for which he used Typha as a study organism. His investigations examined the variation in production, phenotypic traits, and photosynthetic and respiratory biochemistry among populations of Typha throughout the midwestern and western United States. Because Typha overwhelmingly dominates communities, Sam's interpretations of his results spanned ecophysiological adaptation to whole community organization, a theme that would characterize his future influential studies of grassland ecosystems. His first four papers on Typha were published in 1965 and 1966 in Science (McNaughton 1965), Nature (McNaughton 1966a, b), and Ecological Monographs (McNaughton 1966c) demonstrating two features of Sam's science. First, his remarkable productivity, which Larry Wolf, a longtime friend and colleague at SU, explained by Sam's ability to very quickly produce a draft of a manuscript that would require very little further work before submission.
