We conclude that the genitalia of dominant and subordinate males could be a dominant male bank voles may benefit from an enlarged factor contributing to the fertilisation advantage of domi- baculum under sperm competition and/or cryptic female nant males under sperm competition.

POVAR, CONSULTING EDITOR ELVA MATHIESEN, ASSISTANT EDITOR ALLAN M. SCHRIER, FOUNDING EDITOR, 1962-1987 Published Quarterly by the Schrier Research Laboratory Psychology Department, Brown University Providence, Rhode Island ISSN 0023-6861 POLICY STATEMENT The Laboratory Primate Newsletter provides a central source of information about nonhuman primates and re- lated matters to scientists who use these animals in their research and those whose work supports such research. The Newsletter (1) provides information on care and breeding of nonhuman primates for laboratory research, (2) dis- seminates general information and news about the world of primate research (such as announcements of meetings, research projects, sources of information, nomenclature changes), (3) helps meet the special research needs of indi- vidual investigators by publishing requests for research material or for information related to specific research prob- lems, and (4) serves the cause of conservation of nonhuman primates by publishing information on that topic. As a rule, research articles or summaries accepted for the Newsletter have some practical implications or provide general information likely to be of interest to investigators in a variety of areas of primate research. However, special con- sideration will be given to articles containing data on primates not conveniently publishable elsewhere. General descriptions of current research projects on primates will also be welcome. The Newsletter appears quarterly and is intended primarily for persons doing research with nonhuman primates.

Southern Bog Lemming, Synaptomys Cooperi,Andthe Mammals: Their Natural History, Classification, and Meadow Vole, Microtus Pennsylvanicus,Invirginia
Synaptomys cooperi (Baird, 1858) SBLE W. Mark Ford and Joshua Laerm CONTENT AND TAXONOMIC COMMENTS There are eight subspecies of the southern bog lem- ming (Synaptomys cooperi) recognized, four of which occur in the South: S. c. gossii, S. c. helaletes, S. c. kentucki, and S. c. stonei (Wetzel 1955, Barbour 1956, Hall 1981, Linzey 1983, Long 1987). However, Whitaker and Hamilton (1998) indicate that S. c. gossii, S. c. kentucki, and S. c. stonei could be referable to S. c. cooperi.The literature was reviewed by Linzey (1983). DISTINGUISHING CHARACTERISTICS The southern bog lemming is a robust, short-tailed vole with a broad head, small ears, and small eyes. Its measurements are: total length, 119–154 mm; tail, 13–25 mm; hind foot, 16–24 mm; ear, 8–14 mm; weight, 20–50 g. The dental formula for this species is: I 1/1, C 0/0, P 0/0, M 3/3 = 16 (Figure 1). The pel- age is bright chestnut to dark grizzled brown dor- sally, grading into silver grayish white ventrally, with gray to brown feet and tail. The southern bog lemming readily is distinguished from other voles by its short tail (usually less than hind foot length), pres- ence of a shallow longitudinal groove along upper incisors, and deep reentrant angles on molars. See keys for details. CONSERVATION STATUS The southern bog lemming has a global rank of Secure (NatureServe 2007). It is listed as Secure in Virginia and Apparently Secure in Kentucky and Tennessee. It is listed as Vulnerable in North Carolina, Imperiled in Arkansas, and Critically Imperiled in Georgia. -

Punctuated Equilibrium Vs. Phyletic Gradualism
International Journal of Bio-Science and Bio-Technology Vol. 3, No. 4, December, 2011 Punctuated Equilibrium vs. Phyletic Gradualism Monalie C. Saylo1, Cheryl C. Escoton1 and Micah M. Saylo2 1 University of Antique, Sibalom, Antique, Philippines 2 DepEd Sibalom North District, Sibalom, Antique, Philippines [email protected] Abstract Both phyletic gradualism and punctuated equilibrium are speciation theory and are valid models for understanding macroevolution. Both theories describe the rates of speciation. For Gradualism, changes in species is slow and gradual, occurring in small periodic changes in the gene pool, whereas for Punctuated Equilibrium, evolution occurs in spurts of relatively rapid change with long periods of non-change. The gradualism model depicts evolution as a slow steady process in which organisms change and develop slowly over time. In contrast, the punctuated equilibrium model depicts evolution as long periods of no evolutionary change followed by rapid periods of change. Both are models for describing successive evolutionary changes due to the mechanisms of evolution in a time frame. Keywords: macroevolution, phyletic gradualism, punctuated equilibrium, speciation, evolutionary change 1. Introduction Has the evolution of life proceeded as a gradual stepwise process, or through relatively long periods of stasis punctuated by short periods of rapid evolution? To date, what is clear is that both evolutionary patterns – phyletic gradualism and punctuated equilibrium have played at least some role in the evolution of life. Gradualism and punctuated equilibrium are two ways in which the evolution of a species can occur. A species can evolve by only one of these, or by both. Scientists think that species with a shorter evolution evolved mostly by punctuated equilibrium, and those with a longer evolution evolved mostly by gradualism. -

ABDEL-RAHMAN 1, CHRISTIAN T. CHIMIMBA, PETER J. TAYLOR, GIANCARLO CONTRAFATTO, JENNIFER M. LAMB 1 Sudan Natural History Museum, Faculty of Science, University of Khartoum P. O. Box 321 Khartoum, Sudan Non-geographic morphometric variation particularly at the level of sexual dimorphism and age variation has been extensively documented in many organisms including rodents, and is useful for establishing whether to analyse sexes separately or together and for selecting adult specimens to consider for subsequent data recording and analysis. However, such studies have largely been based on linear measurement-based traditional morphometric analyses that mainly focus on the partitioning of overall size- rather than shape-related morphological variation. Nevertheless, recent advances in unit-free, landmark/outline-based geometric morphometric analyses offer a new tool to assess shape-related morphological variation. In the present study, we used geometric morphometric analysis to comparatively evaluate non-geographic variation in two geographically disparate murid rodent species, Aethmoys ineptus from South Africa and Arvicanthis niloticus from Sudan , the results of which are also compared with previously published results based on traditional morphometric data. Our results show that while the results of the traditional morphometric analyses of both species were congruent, they were not sensitive enough to detect some signals of non-geographic morphological variation. -

A New Permanent Cell Line Derived from the Bank Vole (Myodes Glareolus) As Cell Culture Model for Zoonotic Viruses
Essbauer et al. Virology Journal 2011, 8:339 http://www.virologyj.com/content/8/1/339 RESEARCH Open Access A new permanent cell line derived from the bank vole (Myodes glareolus) as cell culture model for zoonotic viruses Sandra S Essbauer1*†, Ellen Krautkrämer2†, Sibylle Herzog3 and Martin Pfeffer4 Abstract Background: Approximately 60% of emerging viruses are of zoonotic origin, with three-fourths derived from wild animals. Many of these zoonotic diseases are transmitted by rodents with important information about their reservoir dynamics and pathogenesis missing. One main reason for the gap in our knowledge is the lack of adequate cell culture systems as models for the investigation of rodent-borne (robo) viruses in vitro. Therefore we established and characterized a new cell line, BVK168, using the kidney of a bank vole, Myodes glareolus, the most abundant member of the Arvicolinae trapped in Germany. Results: BVK168 proved to be of epithelial morphology expressing tight junctions as well as adherence junction proteins. The BVK168 cells were analyzed for their infectability by several arbo- and robo-viruses: Vesicular stomatitis virus, vaccinia virus, cowpox virus, Sindbis virus, Pixuna virus, Usutu virus, Inkoo virus, Puumalavirus, and Borna disease virus (BDV). The cell line was susceptible for all tested viruses, and most interestingly also for the difficult to propagate BDV. Conclusion: In conclusion, the newly established cell line from wildlife rodents seems to be an excellent tool for the isolation and characterization of new rodent-associated viruses and may be used as in vitro-model to study properties and pathogenesis of these agents. Background [3]. Rodents are known to be the reservoir hosts for a About 800 out of the ~1.400 known human pathogens variety of zoonotic viruses which are sometimes tedious are of zoonotic origin [1,2].
