Memorial to Claude William Hibbard 1905-1973 JOHN ANDREW WILSON University of Texas at Austin, Austin, Texas 78712 Dr
Memorial to Claude William Hibbard 1905-1973 JOHN ANDREW WILSON University of Texas at Austin, Austin, Texas 78712 Dr. Claude W. Hibbard was born March 21, 1905, in Toronto, Kansas, and died October 9, 1973, in Ann Arbor, Michigan. He apparently suffered a heart attack early in the morning while at work at the University of Michigan Museum of Paleontology. He was pro fessor of geology and curator of fossil vertebrates at the University of Michigan where he had served con tinuously since 1946. He is survived by his wife, Faye; his daughter, Mrs. John (Katherine) Mull; two grand daughters; his mother, Evie Hibbard of Toronto, Kansas; four brothers; and a sister. He was museum assistant (1928 to 1934), assistant curator of vertebrate paleontology (1935 to 1941), and curator of vertebrate paleontology and assistant professor of zoology (1941 to 1946) at the University of Kansas before going to the University of Michigan. “Hibbie” received his B.A. (1933) and M.A. (1934) in zoology from the University of Kansas and his Ph.D. (1941) in zoology from the University of Michigan. He joined The Geological Society of America in 1945 while he was assistant professor of zoology and curator of fossil vertebrates at the University of Kansas. He worked in four major fields of study simultaneously: education, geology, vertebrate paleontology, and zoology- an indication of his broad training and interest. He began in the field of education as principal of a country grade school at Thrall, Kansas. Some would say he continued his country school technique of teaching throughout his educational career. -
An Inventory of Non-Avian Dinosaurs from National Park Service Areas
Lucas, S.G. and Sullivan, R.M., eds., 2018, Fossil Record 6. New Mexico Museum of Natural History and Science Bulletin 79. 703 AN INVENTORY OF NON-AVIAN DINOSAURS FROM NATIONAL PARK SERVICE AREAS JUSTIN S. TWEET1 and VINCENT L. SANTUCCI2 1National Park Service, 9149 79th Street S., Cottage Grove, MN 55016 -email: [email protected]; 2National Park Service, Geologic Resources Division, 1849 “C” Street, NW, Washington, D.C. 20240 -email: [email protected] Abstract—Dinosaurs have captured the interest and imagination of the general public, particularly children, around the world. Paleontological resource inventories within units of the National Park Service have revealed that body and trace fossils of non-avian dinosaurs have been documented in at least 21 National Park Service areas. In addition there are two historically associated occurrences, one equivocal occurrence, two NPS areas with dinosaur tracks in building stone, and one case where fossils have been found immediately outside of a monument’s boundaries. To date, body fossils of non- avian dinosaurs are documented at 14 NPS areas, may also be present at another, and are historically associated with two other parks. Dinosaur trace fossils have been documented at 17 NPS areas and are visible in building stone at two parks. Most records of NPS dinosaur fossils come from park units on the Colorado Plateau, where body fossils have been found in Upper Jurassic and Lower Cretaceous rocks at many locations, and trace fossils are widely distributed in Upper Triassic and Jurassic rocks. Two NPS units are particularly noted for their dinosaur fossils: Dinosaur National Monument (Upper Triassic through Lower Cretaceous) and Big Bend National Park (Upper Cretaceous). -
Extending Phylogenetic Studies of Coevolution: Secondary Brooks Parsimony Analysis, Parasites, and the Great Apes
Cladistics Cladistics 19 (2003) 104–119 www.elsevier.com/locate/yclad Extending phylogenetic studies of coevolution: secondary Brooks parsimony analysis, parasites, and the Great Apes Daniel R. Brooks* and Deborah A. McLennan Department of Zoology, University of Toronto, 25 Harbord Street, Toronto, Ont., Canada M5S 3G5 Accepted 10 February 2003 Abstract Dowling recently compared the empirical properties of Brooks parsimony analysis (BPA) and the leading method for studying phylogenetic aspects of coevolution, reconciled tree analysis (using the computer program TreeMap), based on a series of simu- lations. Like the majority of authors who have compared BPA with other methods, however, Dowling considered only the form of BPA proposed in 1981 and did not take into account various modifications of the method proposed from 1986 to 2002. This leaves some doubt as to the robustness of his assessments of both the superiority of BPA and its shortcomings. We provide a preecis of the principles of contemporary BPA, including ways to implement it algorithmically, using either Wagner algorithm-based or Hennigian argumentation-based approaches, followed by an empirical example. Our study supports DowlingÕs fundamental conclusions about the superiority of primary BPA relative to TreeMap. However, his conclusions about the shortcomings of BPA due to inclusive ORing (i.e., the production of ghost taxa) are incorrect, as secondary BPA eliminates inclusive ORing from the method. Secondary BPA provides a more complete account of the evolutionary associations between the parasite groups and their hosts than does primary BPA, without sacrificing any indirectly generated information about host phylogeny. Secondary BPA of two groups of nematodes inhabiting Great Apes shows that TreeMap analysis underestimated the amount of cospeciation in the evolution of the nematode genus Enterobius. -

Samuel Wendell Williston
NATIONAL ACADEMY OF SCIENCES S A M U E L W ENDELL WILLISTON 1852—1918 A Biographical Memoir by R I C H A R D SW A N N L U L L Any opinions expressed in this memoir are those of the author(s) and do not necessarily reflect the views of the National Academy of Sciences. Biographical Memoir COPYRIGHT 1919 NATIONAL ACADEMY OF SCIENCES WASHINGTON D.C. SAMUEL WENDELL WILLISTON. 1852-1918. By RICHARD SWANN LULL. PART I.—BIOGRAPHICAL SKETCH. In his immediate family, Prof. Williston stood as a conspicuous figure, as a scholar, a man of research, and one who by an innate superiority made himself what he was. For he owed little to his forebears other than the heritage of those sterling qualities which have made New Englanders in general so vital a force in the evolution of our national character and prestige; his scientific tendencies were an individual characteristic, and he stands as the only recorded Williston to follow lines of scientific research. Williston's father, Samuel Williston, was a blacksmith, and, although a man of considerable native ability, was totally untrained in the affairs of book men. He possessed, however, that pioneer spirit which impelled so many eastern men to migrate to the developing West and seek in a new environment the elusive fortune which the East did not provide. Hence, while Will- iston was born in Boston, his development, in so far as environment exerted a control, was due almost exclusively to the stimulating conditions of the newly invaded West. Here he spent his boyhood. -
Basics of Cladistic Analysis
Basics of Cladistic Analysis Diana Lipscomb George Washington University Washington D.C. Copywrite (c) 1998 Preface This guide is designed to acquaint students with the basic principles and methods of cladistic analysis. The first part briefly reviews basic cladistic methods and terminology. The remaining chapters describe how to diagnose cladograms, carry out character analysis, and deal with multiple trees. Each of these topics has worked examples. I hope this guide makes using cladistic methods more accessible for you and your students.

Diana Lipscomb Weintraub Program in Systematics & Department of Biological Sciences George Washington University Washington D.C. 20052 USA e-mail: [email protected] © 1998, D. Lipscomb 2 Introduction to Systematics All of the many different kinds of organisms on Earth are the result of evolution. If the evolutionary history, or phylogeny, of an organism is traced back, it connects through shared ancestors to lineages of other organisms. That all of life is connected in an immense phylogenetic tree is one of the most significant discoveries of the past 150 years. The field of biology that reconstructs this tree and uncovers the pattern of events that led to the distribution and diversity of life is called systematics. Systematics, then, is no less than understanding the history of all life. In addition to the obvious intellectual importance of this field, systematics forms the basis of all other fields of comparative biology: • Systematics provides the framework, or classification, by which other biologists communicate information about organisms • Systematics and its phylogenetic trees provide the basis of evolutionary interpretation • The phylogenetic tree and corresponding classification predicts properties of newly discovered or poorly known organisms THE SYSTEMATIC PROCESS The systematic process consists of five interdependent but distinct steps: 1. -
Farris, J.S. (In Press) Parsimony and Explanatory Power. Cladistics
Cladistics Cladistics 24 (2008) 1–23 10.1111/j.1096-0031.2008.00214.x Parsimony and explanatory power James S. Farris* Molekyla¨rsystematiska laboratoriet, Naturhistoriska riksmuseet, Box 50007 SE-104 05 Stockholm, Sweden Department of Invertebrate Zoology, American Museum of Natural History, Central Park West at 79th Street, New York, NY 10024, USA Accepted 24 December 2007 Abstract Parsimony can be related to explanatory power, either by noting that each additional requirement for a separate origin of a feature reduces the number of observed similarities that can be explained as inheritance from a common ancestor; or else by applying PopperÕs formula for explanatory power together with the fact that parsimony yields maximum likelihood trees under No Common Mechanism (NCM). Despite deceptive claims made by some likelihoodists, most maximum likelihood methods cannot be justified in this way because they rely on unrealistic background assumptions. These facts have been disputed on the various grounds that ad hoc hypotheses of homoplasy are explanatory, that they are not explanatory, that character states are ontological individuals, that character data do not comprise evidence, that unrealistic theories can be used as background knowledge, that NCM is unrealistic, and that likelihoods cannot be used to evaluate explanatory power. None of these objections is even remotely well founded, and indeed most of them do not even seem to have been meant seriously, having instead been put forward merely to obstruct the development of phylogenetic methods. Ó The Willi Hennig Society 2008. Introduction had been discovered by Tuffley and Steel (1997). Of course no good deed goes unpunished. My derivations By the early 1980s parsimony was already well have been criticized by opponents of parsimony established as the method of choice among phylogenetic (de Queiroz and Poe, 2003; Felsenstein, 2004), by systematists, but the justification of the method still opponents of Popper (Rieppel, 2003), and by inventive seemed incomplete.
