Small Mammal Populations in Riparian Zones of Different-Aged Coniferous Forests
SMALL MAMMAL POPULATIONS IN RIPARIAN ZONES OF DIFFERENT-AGED CONIFEROUS FORESTS R. G. ANTHONY, E. D. FORSMAN, G. A. GREEN, G. WITMER, AND S. K. NELSON ABSTRACT— Small mammals were trapped in riparian zones in young, mature, and old-growth coniferous forests during spring and summer of 1983. Peromyscus manicu- latus was the most abundant species and comprised 76% and 83% of the total captures during spring and summer, respectively. More species, but fewer individuals, were captured on the streamside transects in comparison to the riparian fringe transects, which were 15-20 m from the stream. Six species of Insectivora, including five species of Sorex, were captured in these riparian zones. No species was solely dependent on riparian zones in old-growth forests; however, additional studies are needed to define the specific habitat requirements of Sorex bendirii, Sorex palustris, Neurotrichus gibbsii, Phenacomys albipes, and Microtus richardsoni. Riparian zones recently have been recognized for their uniqueness and intrinsic value as wildlife habitat. To date, much attention has been focused on the most conspicuous riparian zones, such as those found in semiarid lands or along major rivers and streams (Johnson and Jones 1977, Thomas et al. 1979). Studies on wildlife populations in riparian zones dominated by coniferous forests are less numerous (Swanson et al. 1982), although riparian zones along low-order (second-, third-, and fourth-order streams at the head of watersheds) mountain streams are an integral part of the forest ecosystem (Swanson et al. 1982). Harvest of old-growth forests has become a major forestry-wildlife issue, because these forests provide unique wildlife habitat and they are rapidly being logged (Meslow et al. -
Interglacial Refugia Preserved High Genetic Diversity of the Chinese Mole Shrew in the Mountains of Southwest China
Heredity (2016) 116, 23–32 & 2016 Macmillan Publishers Limited All rights reserved 0018-067X/16 www.nature.com/hdy ORIGINAL ARTICLE Interglacial refugia preserved high genetic diversity of the Chinese mole shrew in the mountains of southwest China KHe1,2, N-Q Hu1,3, X Chen4,5, J-T Li6 and X-L Jiang1 The mountains of southwest China (MSC) harbor extremely high species diversity; however, the mechanism behind this diversity is unknown. We investigated to what degree the topography and climate change shaped the genetic diversity and diversification in these mountains, and we also sought to identify the locations of microrefugia areas in these mountains. For these purposes, we sampled extensively to estimate the intraspecific phylogenetic pattern of the Chinese mole shrew (Anourosorex squamipes)in southwest China throughout its range of distribution. Two mitochondrial genes, namely, cytochrome b (CYT B) and NADH dehydrogenase subunit 2 (ND2), from 383 archived specimens from 43 localities were determined for phylogeographic and demographic analyses. We used the continuous-diffusion phylogeographic model, extensive Bayesian skyline plot species distribution modeling (SDM) and approximate Bayesian computation (ABC) to explore the changes in population size and distribution through time of the species. Two phylogenetic clades were identified, and significantly higher genetic diversity was preserved in the southern subregion of the mountains. The results of the SDM, continuous-diffusion phylogeographic model, extensive Bayesian skyline plot and ABC analyses were congruent and supported that the Last Interglacial Maximum (LIG) was an unfavorable period for the mole shrews because of a high degree of seasonality; A. squamipes survived in isolated interglacial refugia mainly located in the southern subregion during the LIG and rapidly expanded during the last glacial period. -

In Arkansas, moles primarily feed on earthworms, grubs and other inverte brates. Moles lack the dental struc ture to chew plant material (seeds, roots, etc.) for food and, as a result, subsist strictly as carnivores. Occasionally moles will cut surface vegetation and bring it down to their nest, as bedding, but this is not eaten. Figure 1.

Comparative Morphology of the Penis and Clitoris in Four Species of Moles
RESEARCH ARTICLE Comparative Morphology of the Penis and Clitoris in Four Species of Moles (Talpidae) ADRIANE WATKINS SINCLAIR1∗, STEPHEN GLICKMAN2, KENNETH CATANIA3, AKIO SHINOHARA4, LAWRENCE BASKIN1, 1 AND GERALD R. CUNHA 1Department of Urology, University of California San Francisco, San Francisco, California 2Departments of Psychology and Integrative Biology, University of California, Berkeley, California 3Department of Biological Sciences, Vanderbilt University, Nashville, Tennessee 4Frontier Science Research Center, University of Miyazaki, Kihara, Japan ABSTRACT The penile and clitoral anatomy of four species of Talpid moles (broad-footed, star-nosed, hairy- tailed, and Japanese shrew moles) were investigated to define penile and clitoral anatomy and to examine the relationship of the clitoral anatomy with the presence or absence of ovotestes. The ovotestis contains ovarian tissue and glandular tissue resembling fetal testicular tissue and can produce androgens. The ovotestis is present in star-nosed and hairy-tailed moles, but not in broad-footed and Japanese shrew moles. Using histology, three-dimensional reconstruction, and morphometric analysis, sexual dimorphism was examined with regard to a nine feature mascu- line trait score that included perineal appendage length (prepuce), anogenital distance, and pres- ence/absence of bone. The presence/absence of ovotestes was discordant in all four mole species for sex differentiation features. For many sex differentiation features, discordance with ovotestes was observed in at least one mole species. The degree of concordance with ovotestes was highest for hairy-tailed moles and lowest for broad-footed moles. In relationship to phylogenetic clade, sex differentiation features also did not correlate with the similarity/divergence of the features and presence/absence of ovotestes. -

DNA sequence data combined with a multivariate analysis of cranial characters, has revealed a high cryptic diversity of the group. An analysis of mitochondrial cytochrome b gene and five nuclear genes has revealed two deeply divergent clades: the western one (E. klossi + E. malayana + E. longirostris from Sichuan + Euroscaptor spp. from northern Vietnam and Yunnan, China), and the eastern one (E. parvidens s.l. + E. subanura). The pattern of genetic variation in the genus Euroscaptor discovered in the present study provides support for the existence of several cryptic lineages that could be treated as distinct species based on their genetic and morphological distinctness and geographical distribution. -

They were captured in a human-modified artificial environment, although mole shrews usually inhabit forests. External and skull measurements indicated that the species was Anourosorex assamensis, previously known only as an endemic species of the Assam region of India. This is the first record of this species from Myanmar. Karyological examination revealed the species was diploid with a fundamental autosomal number of 2n=50 and NFa=96. These numbers correspond to the Taiwanese species A. yamashinai, but several differences were apparent in chromosomal morphology and the position of secondary chromosomal constrictions. The karyological information suggests A. assamensis is a full species separate from A. squamipes in China.

Morphological Diversity in Tenrecs (Afrosoricida, Tenrecidae)
Morphological diversity in tenrecs (Afrosoricida, Tenrecidae): comparing tenrec skull diversity to their closest relatives Sive Finlay and Natalie Cooper School of Natural Sciences, Trinity College Dublin, Dublin, Ireland Trinity Centre for Biodiversity Research, Trinity College Dublin, Dublin, Ireland ABSTRACT It is important to quantify patterns of morphological diversity to enhance our un- derstanding of variation in ecological and evolutionary traits. Here, we present a quantitative analysis of morphological diversity in a family of small mammals, the tenrecs (Afrosoricida, Tenrecidae). Tenrecs are often cited as an example of an ex- ceptionally morphologically diverse group. However, this assumption has not been tested quantitatively. We use geometric morphometric analyses of skull shape to test whether tenrecs are more morphologically diverse than their closest relatives, the golden moles (Afrosoricida, Chrysochloridae). Tenrecs occupy a wider range of ecological niches than golden moles so we predict that they will be more morpho- logically diverse. Contrary to our expectations, we find that tenrec skulls are only more morphologically diverse than golden moles when measured in lateral view. Furthermore, similarities among the species-rich Microgale tenrec genus appear to mask higher morphological diversity in the rest of the family. These results reveal new insights into the morphological diversity of tenrecs and highlight the impor- tance of using quantitative methods to test qualitative assumptions about patterns of morphological diversity.

(December 2005) Laurence John Frabotta, B.S.; M.S., California State University, Long Beach Chair of Advisory Committee: Dr. Rodney L. Honeycutt This dissertation has two major sections. In Chapter II, complete mitochondrial (mt DNA) genome sequences were used to construct a hypothesis for affinities of most major lineages of rodents that arose quickly in the Eocene and were well established by the end of the Oligocene. Determining the relationships among extant members of such old lineages can be difficult. Two traditional schemes on subordinal classification of rodents have persisted for over a century, dividing rodents into either two or three suborders, with relationships among families or superfamilies remaining problematic. The mtDNA sequences for four new rodent taxa (Aplodontia, Cratogeomys, Erethizon, and Hystrix), along with previously published Euarchontoglires taxa, were analyzed under parsimony, likelihood, and Bayesian criteria. -
