Review of the Pliocene and Pleistocene Talpidae (Soricomorpha, Mammalia) of Poland Palaeontologia Electronica palaeo-electronica.org Review of the Pliocene and Pleistocene Talpidae (Soricomorpha, Mammalia) of Poland Barbara Rzebik-Kowalska ABSTRACT Remains of Talpidae (Soricomorpha, Mammalia) from nine Pliocene and Early Pleistocene localities [Podlesice (MN14), Węże 1 (MN15) and 2 (MN15/MN16), Rębie- lice Królewskie 1A and 2 (MN16), Kielniki 3B, and Zamkowa Dolna Cave A (MN17), Kadzielnia 1 (MN17 or MN17/Q1) and Zamkowa Dolna Cave C (Q2)] located in Poland are reviewed. One new genus Skoczenia n. gen. and one new species Quyania euro- paea n. sp. are described. The list of Talpidae species from the Pliocene and Early Pleistocene of Poland now includes Condylura kowalskii, C. izaballae, Parascalops fossilis, ?Scalopoides sp., ?Neurotrichus polonicus, ?N. skoczeni, Quyania europaea n. sp., and Skoczenia copernici n. gen. Where necessary, previously described speci- mens were reevaluated and redescribed, and new illustrations were added. The sys- tematic position, distribution, and number of species in each of the localities are discussed. Barbara Rzebik-Kowalska.

  • 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.

  • Uropsilus, Talpidae): Implications for Taxonomy and Conservation Tao Wan1,2†, Kai He1,3† and Xue-Long Jiang1*
    Wan et al. BMC Evolutionary Biology 2013, 13:232 http://www.biomedcentral.com/1471-2148/13/232 RESEARCH ARTICLE Open Access Multilocus phylogeny and cryptic diversity in Asian shrew-like moles (Uropsilus, Talpidae): implications for taxonomy and conservation Tao Wan1,2†, Kai He1,3† and Xue-Long Jiang1* Abstract Background: The genus Uropsilus comprises a group of terrestrial, montane mammals endemic to the Hengduan and adjacent mountains. These animals are the most primitive living talpids. The taxonomy has been primarily based on cursory morphological comparisons and the evolutionary affinities are little known. To provide insight into the systematics of this group, we estimated the first multi-locus phylogeny and conducted species delimitation, including taxon sampling throughout their distribution range. Results: We obtained two mitochondrial genes (~1, 985 bp) and eight nuclear genes (~4, 345 bp) from 56 specimens. Ten distinct evolutionary lineages were recovered from the three recognized species, eight of which were recognized as species/putative species. Five of these putative species were found to be masquerading as the gracile shrew mole. The divergence time estimation results indicated that climate change since the last Miocene and the uplift of the Himalayas may have resulted in the diversification and speciation of Uropsilus. Conclusions: The cryptic diversity found in this study indicated that the number of species is strongly underestimated under the current taxonomy. Two synonyms of gracilis (atronates and nivatus) should be given full species status, and the taxonomic status of another three potential species should be evaluated using extensive taxon sampling, comprehensive morphological, and morphometric approaches. Consequently, the conservation status of Uropsilus spp.

E-mail: [email protected] Abstract A parasite-host and a host-parasite checklist of helminths found in Soricomorpha (= Insectivora) of North America north of Mexico are presented. The parasite-host checklist includes a total of 114 species of helminth parasites reported in the literature from 28 species of insectivores, totaling 349 records. These include 97 species from shrews (9 trematodes, 34 cestodes, 50 nematodes, 4 acanthocephalans) and 23 species from moles (3 trematodes, 4 cestodes, 10 nematodes, 6 acanthocephalans). Each helminth species is listed under its most current accepted taxon, with all known synonyms, dis- tribution by state/province, and references for each geographic location. The following new combinations are proposed: Lineolepis pribilofensis (Olson, 1969) n. comb. for Hymenolepis pribilofensis Olson, 1969; Monocercus soricis (Nei- land, 1953) n. comb. for Molluscotaenia soricis (Neiland, 1953) Spasskii & Andreiko, 1971; and Eucoleus blarinae (Ogren, 1953) n. comb. for Capillaria blarinae Ogren, 1953. The state of knowledge of helminths of insectivores in North America is briefly discussed. Key words: helminths; Soricomorpha; Insectivora; shrews; moles; North America Introduction Shrews and moles have traditionally been classified in the order Insectivora, but more recently have been placed in the order Soricomorpha (Wilson & Reeder 2005).

  • An Evolutionary View on the Japanese Talpids Based on Nucleotide Sequences
    Mammal Study 30: S19–S24 (2005) © the Mammalogical Society of Japan An evolutionary view on the Japanese talpids based on nucleotide sequences Akio Shinohara1,*, Kevin L. Campbell2 and Hitoshi Suzuki3 1 Department of Bio-resources, Division of Biotechnology, Frontier Science Research Center, University of Miyazaki, Miyazaki 889-1692, Japan 2 Department of Zoology, University of Manitoba, Winnipeg, Manitoba, R3T 2N2, Canada 3 Graduate School of Environmental Earth Science, Hokkaido University, Hokkaido 060-0810, Japan Abstract. Japanese talpid moles exhibit a remarkable degree of species richness and geographic complexity, and as such, have attracted much research interest by morphologists, cytogeneticists, and molecular phylogeneticists. However, a consensus hypothesis pertaining to the evolutionary history and biogeography of this group remains elusive. Recent phylogenetic studies utilizing nucleotide sequences have provided reasonably consistent branching patterns for Japanese talpids, but have generally suffered from a lack of closely related South-East Asian species for sound biogeographic interpretations. As an initial step in achieving this goal, we constructed phylogenetic trees using publicly accessible mitochondrial and nuclear sequences from seven Japanese taxa, and those of related insular and continental species for which nucleotide data is available. The resultant trees support the view that four lineages (Euroscaptor mizura, Mogera tokuade species group [M. tokudae and M. etigo], M. imaizumii, and M. wogura) migrated separately, and in this order, from the continental Asian mainland to Japan. The close relationship of M. tokudae and M. etigo suggests these lineages diverged recently through a vicariant event between Sado Island and Echigo plain. The origin of the two endemic lineages of Japanese shrew-moles, Urotrichus talpoides and Dymecodon pilirostris, remains ambiguous.

  • Life History Account for Townsend's Mole
    California Wildlife Habitat Relationships System California Department of Fish and Wildlife California Interagency Wildlife Task Group TOWNSEND'S MOLE Scapanus townsendii Family: TALPIDAE Order: INSECTIVORA Class: MAMMALIA M016 Written by: G. Hoefler, J. Harris Reviewed by: H. Shellhammer Edited by: S. Granholm DISTRIBUTION, ABUNDANCE, AND SEASONALITY Townsend's mole is found along the North Coast in Del Norte and Humboldt cos., from the Oregon border south through about two-thirds of Humboldt Co. Optimum habitats are annual grassland, wet meadow, and early seral stages of redwood, Douglas-fir, mixed conifer, and montane hardwood-conifer forests. Townsend's mole in California mainly is a species of lowland river bottoms. SPECIFIC HABITAT REQUIREMENTS Feeding: Earthworms comprise 55-86% of the diet, with the remainder insects, seeds, roots, leaves, slugs, snails, and small mammals (Wight 1928, Moore 1933, Pedersen 1963, Whitaker et al. 1979). Forages beneath the surface in light, base-rich soils. Cover: This mole is almost entirely subterranean, spending its time in underground burrow systems. Requires well-drained, friable soil for burrowing. Reproduction: Nests in a grass-lined cavity 15-20 cm (6-8 in) below the surface. Nests sometimes are placed under "fortresses" (large mounds of earth 75-125 cm (30-50 in) in diameter), or near the center of a cluster of several normal-sized mounds (Kuhn et al. 1966, Maser et al. 1981). Water: Water needs are met from the diet, especially from earthworms. Pattern: Prefers well-drained, friable soils. Avoids dense woods and thickets. Clearing, draining, and fertilizing of cropland and pasture may have increased numbers of Townsend's mole.
