Understanding the history of diversification in the North American deserts has long been a goal of biogeographers and evolutionary biologists. While it seems that a consensus is forming regarding the patterns of diversification in the Nearctic deserts in vertebrate taxa, little work has been done exploring the historical biogeography of widespread invertebrate taxa. Before a robust model of geobiotic change in the North American deserts can be proposed, it needs to be determined if the same historical events affected vertebrate and invertebrate taxa in the same way. I explored the phylogeographic patterns in four groups of widespread nocturnal velvet ants using two rDNA loci, the internal transcribed spacer regions 1 and 2 (ITS1 and ITS2). I used Bayesian phylogenetic analyses and haplotype network analyses to determine if a consistent geographic pattern exists among species and populations within each group. I also used molecular dating techniques to estimate divergence dates for each of the major phylogenetic clades. These analyses indicate that the species-level divergences in some groups occurred in the Neogene, and likely were driven by mountain building during Miocene-Pliocene times (~5 Ma) similar to the divergences in many vertebrate taxa, while species-level divergence in other groups occurred during the Pleistocene (1.8-0.1 Ma) and were likely driven by climatic oscillations and range contractions and expansion. Several recent studies have suggested that Neogene mountain-building events were more important to the development of a diverse desert-adapted biota. My research suggests, however, that both Neogene events and Pleistocene climatic changes were influential in the development of a species-rich nocturnal velvet ant fauna.

This book discusses the evolution of the mechanisms by which prey avoid attack by their potential predators and questions how such defences are maintained through natural selection. Topics covered include camouflage, warning signals and mimicry.

"Bees play an essential role in the pollination of native plants and agricultural crops across the globe. In North America alone there are more than 4,000 bee species. In spite of their abundance and diversity, there is no accessible field guide for the non-expert. This book will remedy that situation by providing a carefully crafted introduction to bee identification for eastern North America. No portable field guide could include coverage of the myriad species in the region, so the book concentrates on identifying bees at the genus level. It includes information on the 72 different genera that are found east of the Rockies"--

Excerpt from The Ants of North America The bibliographic citations carried for each species and subspecies have been extensively edited. It is no longer practical to present full bibliographies for many of our species. In recent years many regional studies dealing with the distribution of our ants have been published. Much use has been made of such studies in preparing the ranges pre sented herein. But I cannot feel that this type of publication should be listed in the bibliography of each species which it covers. It has been assumed that if the reader of this book finds it necessary to look up references given under the various species, it will be because he wishes to secure a fuller knowledge of the structure of the insects than can be obtained from the keys. Considerable effort has been made to see that all such references apply to descriptive material or to points which elucidate the taxonomy of the species involved. Papers which carry only distributional records have been placed in the general bibliography at the end of the volume.
