Thus, the included checklist and dichotomous key contain 101 species of mammals. Of the native species, 36 are rodents, 20 carnivores, 13 bats, 7 shrews and mole, 7 even-toed ungulates, 4 rabbits and hares, 1 armadillo, and 1 opossum. Another 8 species are identied as potentially occurring in peripheral areas of Nebraska. The bibliography includes 1693 entries that each contain data concerning one or more species of mammals from Nebraska.

The head-body Order: Rodentia length is about three to four inches. The claws on the front feet are larger than the ones on the back Family: Cricetidae feet. The tail is very short, and the eyes are tiny. ILLINOIS STATUS common, native BEHAVIORS The woodland vole may be found statewide in Illinois. This rodent lives on the forest floor in dry woods with oaks, hickories and maples. It also lives in roadside vegetation, orchards, pastures and weedy fields. The woodland vole eats berries, roots, nuts, seeds, wild onions and a variety of green vegetation. It is active day and night. This vole uses burrows under the soil that it digs or that were dug by other small mammals. It digs with the front feet, using the hind feet to push the loose soil behind it. representative specimen The head is used to push loose dirt out of the burrow. The nest is built in a burrow or under an object on the ground that can be reached by a branch of the burrow. Several woodland voles may use the same nest. Two mating seasons occur in a year with young born from March through April and August through November. A litter contains two or three young. Young are helpless at birth but develop rapidly, living on their own at about three weeks of ILLINOIS RANGE age. Sexual maturity is attained between two and three months of age.

  • The Beaver's Phylogenetic Lineage Illuminated by Retroposon Reads

However, Accepted: 25 January 2017 for many organisms such data are still not available. Among rodents, the phylogenetic position of the Published: 03 March 2017 beaver has always attracted special interest. The arrangement of the beaver’s masseter (jaw-closer) muscle once suggested a strong affinity to some sciurid rodents (e.g., squirrels), placing them in the Sciuromorpha suborder. Modern molecular data, however, suggested a closer relationship of beaver to the representatives of the mouse-related clade, but significant data from virtually homoplasy- free markers (for example retroposon insertions) for the exact position of the beaver have not been available. We derived a gross genome assembly from deposited genomic Illumina paired-end reads and extracted thousands of potential phylogenetically informative retroposon markers using the new bioinformatics coordinate extractor fastCOEX, enabling us to evaluate different hypotheses for the phylogenetic position of the beaver. Comparative results provided significant support for a clear relationship between beavers (Castoridae) and kangaroo rat-related species (Geomyoidea) (p < 0.0015, six markers, no conflicting data) within a significantly supported mouse-related clade (including Myodonta, Anomaluromorpha, and Castorimorpha) (p < 0.0015, six markers, no conflicting data). Most of an organism’s phylogenetic history is fossilized in their heritable genomic material. Using data from genome sequencing projects, particularly informative regions of this material can be extracted in sufficient num- bers to resolve the deepest history of speciation.

    Characterisation of Community-Derived Hymenolepis Infections in Australia Marion G. Macnish BSc. (Medical Science) Hons Division of Veterinary and Biomedical Sciences Murdoch University Western Australia This thesis is presented for the degree of Doctor of Philosophy of Murdoch University 2001 I declare that this thesis is my own account of my research and contains as its main work which has not been submitted for a degree at any other educational institution. ………………………………………………. (Marion G. Macnish) Characterisation of Community-Derived Hymenolepis Infections in Australia ii Abstract Hymenolepis nana is a ubiquitous parasite, found throughout many developing and developed countries. Globally, the prevalence of H. nana is alarmingly high, with estimates of up to 75 million people infected. In Australia, the rates of infection have increased substantially in the last decade, from less than 20% in the early 1990’s to 55 - 60% in these same communities today. Our knowledge of the epidemiology of infection of H. nana is hampered by the confusion surrounding the host specificity and taxonomy of this parasite. The suggestion of the existence of two separate species, Hymenolepis nana von Siebold 1852 and Hymenolepis fraterna Stiles 1906, was first proposed at the beginning of the 20th century. Despite ongoing discussions in the subsequent years it remained unclear, some 90 years later, whether there were two distinct species, that are highly host specific, or whether they were simply the same species present in both rodent and human hosts. The ongoing controversy surrounding the taxonomy of H. nana has not yet been resolved and remains a point of difference between the taxonomic and medical literature.

DALQUEST, EDWARD ROTH, AND FRANK JUDD SYNOPSIS: Vertebrate remains from two levels in Schulze Cave, Edwards County, Texas, are analyzed. The younger materials probably date from ca. 5,000 B.P. to 8,800 B.P. The fauna is essentially modern, but the absence of the armadillo collared peccary, ringtail, and rock squirrel is thought to be significant. The older materials probably date from ca. 11,000 B.P. to 8;000 B.P. The mam- malian fauna of these Pleistocene sediments includes 62 species, of which 8 are extinct, 19 are not now regident on the Edwards Plateau, and 40 still live in the general area of the cave. Three species have not previously been reported from Pleistocene deposits in Texas: vagrant shrew, eastern chipmunk, and western jumping mouse.

Molecular and morphological data suggested that it is the living fossil and a ‘‘Lazarus taxon.’’ sole representative of a new mammalian family, the Laonastidae, The two research teams also disagreed on the taxonomic and a member of the Hystricognathi. However, the validity of this position of Laonastes. According to Jenkins et al. (2), Laonastes family is controversial because fossil-based phylogenetic analyses is either the most basal group of the hystricognaths (Fig. 2A)or suggest that Laonastes is a surviving member of the Diatomyidae, nested within the hystricognaths (Fig. 2B). According to Dawson a family considered to have been extinct for 11 million years. et al. (3), Laonastes and the other Diatomyidae are the sister According to these data, Laonastes and Diatomyidae are the sister clade of the family Ctenodactylidae (i.e., gundies), a family that clade of extant Ctenodactylidae (i.e., gundies) and do not belong does not belong to the Hystricognathi, but to which it is to the Hystricognathi.
