Phylogenetic Relationships and Historical Bioegeography of the Genus Akodon (Rodentia, Muridae) Using a Multi- Gene Approach PHYLOGENETIC RELATIONSHIPS AND HISTORICAL BIOGEOGRAPHY OF THE GENUS AKODON (RODENTIA: CRICETIDAE) By BRANDI S. COYNER Bachelor of Science, Zoology University of Oklahoma Norman, OK 2005 Submitted to the Faculty of the Graduate College of the Oklahoma State University in partial fulfillment of the requirements for the Degree of DOCTOR OF PHILOSOPHY December, 2010 PHYLOGENETIC RELATIONSHIPS AND HISTORICAL BIOGEOGRAPHY OF THE GENUS AKODON (RODENTIA: CRICETIDAE) Dissertation Approved: Dr. Ronald A. Van Den Bussche Dissertation Adviser Dr. Janet K. Braun Dr. Meredith J. Hamilton Dr. David M. Leslie, Jr. Outside Committee Member Dr. Mark E. Payton Dean of the Graduate College ii ACKNOWLEDGMENTS I thank my committee members (Dr. Janet K. Braun, Dr. Meredith J. Hamilton, Dr. David M. Leslie, Jr., and Dr. Ronald A. Van Den Bussche) for their guidance and patience during my time under their tutelage. I would like to thank Dr. Ronald J. Tyrl, who retired prior to completion of my degree, but who provided much assistance during his time as my committee member. It is also without hesitation that I thank Dr. Michael A. Mares for his continued presence and support of my research and career as a mammalogist and for serving as a mentor. I would like to thank my many lab mates that have come and gone during my time as a member of the Van Den Bussche lab. I also thank the many graduate students that I have shared my time with, especially those that I consider my closest friends despite the distance that careers will put between us. I also thank my family, who despite not always understanding what I do or why I do it, still support me in my endeavors. Without a number of entities, this research would not have been possible. The Departments of Zoology at Oklahoma State University and at the University of Oklahoma are thanked for providing facilities and logistic support, as is the Sam Noble Oklahoma Museum of Natural History. The Recombinant DNA/Protein Core Facility at Oklahoma State University allowed me access to their equipment; I especially thank Janet Rogers and Lisa Whitworth for their assistance while at the Core and their iii willingness to provide assistance with troubleshooting. I am grateful to the many curators and collections managers from the following institutions that have facilitated the loans of tissues and specimens included in this project: Oklahoma Center for iv Genomic Resources, Sam Noble Oklahoma Museum of Natural History, Norman, Oklahoma; Field Museum of Natural History, Chicago, Illinois; Museum of Southwestern Biology, University of New Mexico, Albuquerque, New Mexico; Museum of Vertebrate Zoology, University of California, Berkeley, Berkeley, California; Museum of Texas Tech University, Texas Tech University, Lubbock, Texas; and the American Museum of Natural History, New York, New York. I would like to thank the following organizations and institutions for financial support of this research. Funding for this research was provided by the National Science Foundation Graduate Research Fellowship Program, the Albert M. and Alma Shadle Fellowship in Mammalogy from the Buffalo Foundation and the American Society of Mammalogists, the American Society of Mammalogists’ Grants-in-Aid program, and the Oklahoma State University Zoology Graduate Student Society. Additionally travel grants to present findings from this research at national and international meetings were provided by the Oklahoma State University Graduate and Professional Student Society, Alaska EPSCoR, and the University of Wyoming. Last, but definitely not least, I thank the many individuals that assisted in the field collection of these specimens. They risked loss of life and limb, gave up time with their families, and endured sometimes harsh conditions to collect these mice. Without them, this project would not have been possible. iv TABLE OF CONTENTS Chapter Page I.

Comparative Cytogenetics 11(4): 833–892. https://doi. org/10.3897/CompCytogen.v11i4.19925 Abstract Rodents constitute one of the most diversified mammalian orders. Due to the morphological similarity in many of the groups, their taxonomy is controversial. Karyotype information proved to be an important tool for distinguishing some species because some of them are species-specific. Additionally, rodents can be an excellent model for chromosome evolution studies since many rearrangements have been described in this group.This work brings a review of cytogenetic data of Brazilian rodents, with information about diploid and fundamental numbers, polymorphisms, and geographical distribution.

  • The Pattern of Color Change in Small Mammal
    Sandoval Salinas et al. BMC Res Notes (2018) 11:424 https://doi.org/10.1186/s13104-018-3544-x BMC Research Notes RESEARCH NOTE Open Access The pattern of color change in small mammal museum specimens: is it independent of storage histories given museum‑specifc conditions? María Leonor Sandoval Salinas1,2*, José D. Sandoval1,3, Elisa M. Colombo1,3 and Rubén M. Barquez2 Abstract Objective: Determination of color and evaluating its variation form the basis for a broad range of research questions. For studies on taxonomy, systematics, etc., resorting to mammal specimens in museum collections has a number of advantages over using feld specimens. However, if museum specimens are to be for studying color, they should accurately represent the color of live animals, or we should understand how they difer. Basically, this study addresses this question: How does coat color vary when dealing with specimens of Akodon budini (Budin’s grass mouse, Thomas 1918), stored in one museum collection for diferent periods of time? Results: We measured color values through a spectroradiometer and a difuse illumination cabin and used the refectance values in the form of CIELab tri-stimulus values, considering CIE standard illuminant A. We observed that there is a relationship between specimen storage antiquity and pelage color and it seems that it is general for at least a number of small mammals and this could indicate a universal phenomenon across several mammal species and across several storage conditions. Our results, as others, emphasize the importance of considering storage time, among other circumstances, in research studies using mammal skins and where color is of importance.

Wittouck, E. Pinna Senn, C. A. Sonez, M. C. Provensal, J. J. Polop and J. A. Lisanti Departamento de Ciencias Naturales. Universidad Nacional de Rio Cuarto . (5800). Rio Cuarto, Argentina Accepted March 9, 1995 The complex cricetid genus Akodon, with its five subgenera and more than 40 species (Apfelbaum and Reig 1989, Reig 1987) is characterized by several features that make it very interesting for cytogenetical research, such as intraspecific variation of the autosomes and sex chromosomes, the existence of XY fertile females in some species, and the presence of different species that show apparently identical karyotypes (Bianchi and Merani 1984, Bianchi et al. 1971, 1979a, b, 1989, Gallardo 1982, Maia and Langguth 1981, Reig 1987, Vitullo et al. 1986, and references therein). Two closely related species of the genus, Akodon dolores and A. molinae, share the G-band pattern of their chromosomal arms (Bianchi et al. 1979a) and produce fertile hybrids, at least in laboratory conditions (Merani et al. 1978, Roldan et al. 1984). Their populations present Robertsonian polymorphisms affecting one chromosome pair in A. molinae (Bianchi et al. 1973), and this one and several other pairs in A. dolores (Bianchi et al. 1979a). We report here karyological analyses on some populations assigned to A. dolores on morphological grounds and on hybrid specimens, and show that one of these populations corresponds karyotypically to A. molinae. Craniometric studies fail to differentiate between populations with "dolores" or "molinae" karyotype .
