Mammals of Ungava & Labrador : the 1882-1884 fieldnotes of Lucien M. Turner, together with Inuit and Innu knowledge by Lucien M Turner( Book )

4 editions published in 2014 in English and held by 111 WorldCat member libraries worldwide

"In 1882 the Smithsonian Institution Arctic scientist, Lucien McShan Turner, travelled to the Ungava District (encompassing Northern Quebec and Labrador) where he spent 20 months as part of a mission to record meteorological data for an International Polar Year research program. While stationed at the Hudson's Bay Company Trading Post of Ft. Chimo in Ungava Bay, now the Inuit community of Kuujjuaq, he expanded his duties to studies of the natural history and ethnography of the Inuit and Innu - the Aboriginal peoples of the region. His ethnography of the Inuit and Innu people was published in 1894, but his substantial writings on language and natural history never made it to print. Presented here for the first time is the natural history material that Lucien M. Turner wrote on mammals of the Ungava and Labrador Region. His writings provide a glimpse of the habits and species of mammals that roamed Ungava some 130 years ago in what was an "unknown frontier" to non-Inuit and non-Innu people. Illustrations of mammals feature prominently in the book, as do stories about mammals by present day Inuit from the Ungava region. The book also includes photos of mammals and mammal-orientated ethnographic material that Turner collected in Ungava. This book will be of immense interest to anthropologists, zoologists, Arctic researchers, Northern educators, historians, linguists, storytellers, and to the Inuit and Innu people"--
Quaternary murid rodents of Timor. Part 1, New material of Coryphomys buehleri Schaub, 1937, and description of a second species of the genus by K. P Aplin( Book )

1 edition published in 2010 in English and held by 17 WorldCat member libraries worldwide

Large collections of fragmentary animal bones excavated from archaeological contexts in East Timor between 1968 and 2002 provide new material referable to the recently extinct, gigantic murine genus Coryphomys. We document the upper and lower dentition and palatal anatomy of C. buehleri Schaub, 1937, and identify and name a second species of Coryphomys, based on differences in molar size and morphology and skeletal robusticity. Alternative interpretations of the observed morphological and metric variability (sexual dimorphism, resource-based polymorphism, sample heterochroneity) are each carefully assessed and rejected, and we conclude that the genus comprised two species of approximately similar body size. Preserved cranial elements of both species of Coryphomys feature a high degree of anatomical specialization, including an unusual elaboration of the maxillary sinus complex. Though the specialized anatomy of Coryphomys invites consideration of its phylogenetic relationships, this exercise is hindered by a demonstrable high level of homoplasy (i.e., multiple, independent evolutionary losses and gains) in many of the key craniodental features traditionally surveyed within Murinae, while other features are insufficiently well surveyed for broad-scale analysis. Nevertheless, our comparisons highlight two potentially related lineages among the geographically proximate Murinae - the Philippine Phloeomyini and the Australo-Papuan Hydromyini. The remains of Coryphomys are relatively scarce in all the archaeological samples, but distributional evidence suggests that both species of Coryphomys were found primarily in upland habitats. Late Pleistocene samples document their former presence at lower elevations, possibly reflecting cooler climatic conditions at that time

Global trends and biases in new mammal species discoveries by DeeAnn M Reeder( Book )

2 editions published in 2007 in English and held by 11 WorldCat member libraries worldwide

Contrary to common perception, the number of living mammal species and the relationship of those species with one another are incompletely understood. Taxonomic revisions within mammals are frequent and are often motivated by the discovery of new species. In fact, an analysis of patterns of discovery suggests that complete alpha-taxonomic characterization of living mammals remains a far-off goal. Examination of chronological, geographical, and taxonomic trends in new species discoveries reveals interesting trends, telling biases, and priorities for further study. An average of 223 new valid species have been described per decade since the birth of modern taxonomic nomenclature in 1758, and this rate is increasing. Over 300 new mammal species are expected to be described this decade and some estimates suggest that 7,000+ living species of mammals will eventually be recognized. An analysis of 341 recently described species indicates that the great majority of them are restricted to threatened areas of high endemism -- reiterating the biotic richness of these regions, but also indicating that most new species and the regions in which they occur require urgent conservation attention. That the global mammal fauna remains so incompletely characterized reflects the woeful state of knowledge of global biodiversity

A review of Microhydromys (Rodentia, Murinae), with description of a new species from southern New Guinea by K. M Helgen( Book )

1 edition published in 2010 in English and held by 2 WorldCat member libraries worldwide

The murine rodent genus Microhydromys Tate and Archbold, 1941, includes the smallest of the native rodents of New Guinea and is the rarest Australo-Papuan rodent genus preserved in world museums. We discuss the morphological characteristics of Microhydromys and diagnose two species in the genus: M. richardsoni Tate and Archbold, 1941, distributed over northern New Guinea, and M. argenteus, n. sp., recorded from three localities in southern New Guinea. The only other species previously classified in the genus--Microhydromys musseri Flannery, 1989--is re-allocated to the genus Pseudohydromys Rümmler, 1934. The little available information relating to their biology indicates the species of Microhydromys to be terrestrial inhabitants of foothill and lower montane forest formations and probably naturally rare in those environments

A review of Peroryctes broadbenti, the giant bandicoot of Papua New Guinea by K. P Aplin( Book )

1 edition published in 2010 in English and held by 2 WorldCat member libraries worldwide

The giant bandicoot, Peroryctes broadbenti (Ramsay, 1879), is represented in museum collections by 23 specimens collected at 12 localities in the lowlands of the southeastern peninsula (the "Papuan Peninsula") of Papua New Guinea. Available data on P. broadbenti are reviewed, including its comparative anatomy and morphological variability, taxonomic relationships, geographic and elevational distribution, dietary and reproductive traits, and conservation status. Despite previous confusion between this species and P. raffrayana (Milne-Edwards, 1878), the two species are readily distinguished by a suite of external, cranial, and dental characters. Diagnostic characters are enumerated and illustrated, and comparisons drawn with other New Guinean bandicoots. Generic distinction of Peroryctes Thomas, 1906, in cranial morphology from other New Guinean bandicoots is also reviewed. A striking degree of sexual dimorphism is documented in both body size and dentition for P. broadbenti; these comparisons are set in context by a review of sexual dimorphism among bandicoots in general

A new genus of rodent from Wallacea (Rodentia: Muridae: Murinae: Rattini), and its implication for biogeography and Indo-Pacific Rattini systematics( )

1 edition published in 2013 in English and held by 1 WorldCat member library worldwide

Abstract We describe Halmaheramys bokimekot Fabre, Pagès, Musser, Fitriana, Semiadi & Helgen gen. et sp. nov., a new genus and species of murine rodent from the North Moluccas, and study its phylogenetic placement using both molecular and morphological data. We generated a densely sampled mitochondrial and nuclear DNA data set that included most genera of Indo-Pacific Murinae, and used probabilistic methodologies to infer their phylogenetic relationships. To reconstruct their biogeographical history, we first dated the topology and then used a Lagrange analysis to infer ancestral geographic areas. Finally, we combined the ancestral area reconstructions with temporal information to compare patterns of murine colonization among Indo-Pacific archipelagos. We provide a new and comprehensive molecular phylogenetic reconstruction for Indo-Pacific Murinae, with a focus on the Rattus division. Using previous results and those presented in this study, we define a new Indo-Pacific group within the Rattus division, composed of Bullimus, Bunomys, Paruromys, Halmaheramys, Sundamys, and Taeromys. Our phylogenetic reconstructions revealed a relatively recent diversification from the Middle Miocene to Plio-Pleistocene associated with several major dispersal events. We identified two independent Indo-Pacific dispersal events from both western and eastern Indo-Pacific archipelagos to the isolated island of Halmahera, which led to the speciations of H. bokimekot gen. et sp. nov. and Rattus morotaiensis Kellogg, 1945. We propose that a Middle Miocene collision between the Halmahera and Sangihe arcs may have been responsible for the arrival of the ancestor of Halmaheramys to eastern Wallacea. Halmaheramys bokimekot gen. et sp. nov. is described in detail, and its systematics and biogeography are documented and illustrated. © 2013 The Linnean Society of London
