Central to the knowledge base of Yellowstone wolves is the Yellowstone Wolf Project. If the reader sees a fact, somehow it is related to or derived from the efforts of personnel at the Yellowstone Wolf Research Project. It is important to note that one biologist or person may report ideas or findings that are, in fact, the result of many researchers and volunteers collaborating with the Wolf Project and with the Yellowstone Wolf Genealogy. To each of the volunteers, official and non-official, who helped, especially for their long, cold hours, we also give special thanks. We thank everyone who has contributed to the historical development of ideas, concepts, and research.
