Book Description
In this study I provide a phylogenetic hypothesis for the tribe Oryzomyini that can be used to understand the diversification and evolution of this group of rodents and to revise the current generic-level classification. Morphological and molecular data were used for these purposes in combined and separate analyses. Molecular data consisted of partial sequences (1266 bp) from the first exon of the nuclear gene encoding the interphotoreceptor retinoid binding protein (IRBP); the morphological matrix comprised 99 characters, including 16 integumental characters, 32 skull characters, 29 dental characters, 7 postcranial characters, and 10 characters from the phallus and soft-anatomy systems. I present anatomical descriptions for each character, including delineation of different states observed among oryzomyines. Results of the combined analysis were congruent with the IRBP-only dataset for oryzomyine higher-level relationships. Morphological analyses, although showing discrepancies from the combined or IRBP consensus cladograms and with low nodal support values, recovered several clades similar to the combined and IRBP analyses. Systematics of the tribe and the evolution of a few pivotal characters are discussed in light of the proposed phylogeny. Different taxonomic arrangements for species currently included in the genus Oryzomys are suggested. Finally, I evaluate evolutionary and biogeographic hypotheses that are compatible with our current knowledge on oryzomyine relationships.

Book Description
Oliver P. Pearson’s studies on mammalian biology remain standard reading for ecologists, physiologists, taxonomists, and biogeographers. Reflecting this, the papers gathered here continue to expand our understanding of the ecology and evolution of subterranean mammals, and of ecology, taxonomy, and biogeography of Neotropical mammals, a group that was central to the latter half of Pearson’s career.

Book Description
Rodent Societies synthesizes and integrates the current state of knowledge about the social behavior of rodents, providing ecological and evolutionary contexts for understanding their societies and highlighting emerging conservation and management strategies to preserve them. It begins with a summary of the evolution, phylogeny, and biogeography of social and nonsocial rodents, providing a historical basis for comparative analyses. Subsequent sections focus on group-living rodents and characterize their reproductive behaviors, life histories and population ecology, genetics, neuroendocrine mechanisms, behavioral development, cognitive processes, communication mechanisms, cooperative and uncooperative behaviors, antipredator strategies, comparative socioecology, diseases, and conservation. Using the highly diverse and well-studied Rodentia as model systems to integrate a variety of research approaches and evolutionary theory into a unifying framework, Rodent Societies will appeal to a wide range of disciplines, both as a compendium of current research and as a stimulus for future collaborative and interdisciplinary investigations.

Book Description
This paper presents the first comprehensive taxonomic revision of the olingos, Bassaricyon, based on most available museum specimens, with data derived from anatomy, mitochondrial and nuclear DNA, fieldwork, and geographic range modeling. Olingos are forest-living, arboreal, nocturnal, frugivorous, and solitary, and have one young at a time. Four olingo species can be recognized, including a Central American species (B. gabbii) and lowland species with eastern, cis-Andean (B. alleni) and western, trans-Andean (B. medius) distributions. Surprisingly, the sister lineage to all previously described species of Bassaricyon is an Andean cloud forest species, which we call the Olinguito, that has never been previously described. Bassaricyon neblina sp. n., en-demic to Colombia and Ecuador, is the smallest living member of the family Procyonidae and the first new species of Carnivora named in the American continents in 35 years. We describe four subspecies of Olinguito across the Northern Andes.
