Alfred Russel Wallace Notes 23: The Jersey Devil, And Friends, Charles H. Smith

Faculty/Staff Personal Papers

For nearly three hundred years reports have surfaced of a purported cryptid form known as the ‘Jersey devil.’ In this work an interpretation of the goals of biogeography is given, and how this field can be related to such alleged phenomena, as well as to some of the ideas of Alfred Russel Wallace (1823-1913) that seem to find their origin in the writings of Benedict de Spinoza (1632-1677).

Delineation Of Undescribed, Morphologically Cryptic Cave Beetles Of The Pseudanophthalmus Pubescens Species-Group (Coleoptera: Carabidae: Trechinae), Jedidiah John Nixon

Masters Theses & Specialist Projects

The genus Pseudanophthalmus Jeannel is a widespread and extremely diverse taxon of troglobiont beetle endemic to the karst of eastern North America, with its distribution centered in Tennessee and Kentucky. Despite lying near the heart of this region, the pubescens species-group was thought to contain many undescribed species. In this study, the validities of several of the late Dr. Thomas Barr’s unpublished putative new species in the pubescens-group were tested both morphologically and molecularly. Body measurements (length and width for head, thorax, and abdomen), as well as male genital morphology were compared to see if they reflected theorized species limits.. …

Phylogeny Of The Oniticellini And Onthophagini Dung Beetles (Scarabaeidae, Scarabaeinae) From Morphological Evidence, T. Keith Philips

Biology Faculty Publications

A phylogenetic study was conducted to hypothesize relationships of most of the genera of the Oniticellini and Onthophagini for the first time using morphological characters from a diverse array of external and internal sclerites. The monophyly and sister relationship of both tribes was found using Bayesian and parsimony analyses with heavily to moderately weighted data. An alternative hypothesis based on parsimony analyses of unweighted or slightly weighted data show a paraphyletic Oniticellini without the Onthophagini, although recognition of the subtribe Helictopleurina as a tribe would eliminate non-monophyly.

Of the three Oniticellini subtribes, the Helictopleurina and Drepanocerina are monophyletic. There is …

Historical Biogeography: Geography As Evolution, Evolution As Geography, Charles H. Smith

DLPS Faculty Publications

Despite a number of advances in recent years, biogeography remains a field with a poorly developed philosophical core. As a result, its historical and ecological sides remain as isolated from one another as ever. In this essay I argue that a more unified approach to biogeographic studies will become possible only when workers realise that it is necessary to reject absolute space, "geography as handmaiden" approaches to distribution problems in favour of structuralist models compatible with both probabilistic spatial interaction and deterministic phylogenetic kinds of thinking. Pros and cons of regionalist, vicariance, and panbiogeographic approaches are weighed in this regard; …
