Robert G. Jager is a retired former Professor of Biology at the Unviersity of Lousiana at Lafayette. He has spent the last forty years working on territoriality and interspecific competition in the red-backed salamanders, Plethodon cinereus. He is currently retired but continues to publish actively. Current research examines social behavior and, in particular, social monogamy/polygamy in red-backed salamanders. Birgit Gollmann is a Researcher at the Institut fur Zoologie at the Universitat Wien in Vienna, Austria. Carl D. Anthony is a Professor in the Biology Department at John Carroll University. Caitlin Gabor is a Professor of Biology at Texas State University. Nancy Kohn is an adjunct faculty member in the department of Biology at the College of New Jersey.
The research program of Jaeger et al. has had a profound effect not only on our understanding of red-backed salamanders, but has also made clear how remarkably complex animal behavior can be in species once considered lowly and simple. [...] Finally, this volume ends with a call to future scientists: [the studies] reviewed in this book have produced a jigsaw puzzle of P. cinereus, with only a few of the pieces fitting together. We hope that younger colleagues now studying P. cinereus will complete the jigsaw puzzle, or at least add new pieces to it (p. 207). I was certainly inspired to sit down at the puzzle table. -- Andrew Kraemer, The Quarterly Review of Biology
