Squirrels and Allies (Sciuridae Spp.)
Squirrels and Allies (Sciuridae Spp.) There are about 275 species of tree, ground, and flying squirrels throughout the world, ranging from the five-inch pygmy squirrel (Myosciurus pumilio) of Africa to the nearly three-foot giant squirrel (Ratufa indica) of Asia. Currently, there are five species of squirrel found in Rhode Island: The Eastern gray squirrel, the Southern flying squirrel, the red squirrel, the chipmunk, and the woodchuck. Tree squirrels are those species that nest in trees, while ground squirrels nest in underground burrows. This publication is intended to provide information on the above species found in Rhode Island. Eastern Gray Squirrel (Sciurus carolinensis) Gray squirrels are the most common species of squirrel in Rhode Island. They are a tree squirrel, however they spend much of their time on the ground, and have adapted well to human-altered environments. They are commonly found in urban and suburban habitats. Gray squirrels can be grayish-brown, gray or black, with a white or light brown underside. Adults range in size from 15 to 20 inches, and between 1 to 1 ½ pounds. Their bushy tail accounts for almost half of their length. Gray squirrels may live between four and eight years in the wild, but they have been known to live up to ten years in captivity. They are active mainly during the day and do not hibernate. In the winter they spend days at a time in their nests, leaving only to gather food. Their habitat is mainly any wooded area with mast producing trees, where they live in tree cavities or leaf nests. -
Genetic Structure of the North American Porcupine (Erethizon Dorsatum) Across Western Texas
GENETIC STRUCTURE OF THE NORTH AMERICAN PORCUPINE (ERETHIZON DORSATUM) ACROSS WESTERN TEXAS by Erica D. Thomas A Thesis Submitted in Partial Fulfillment Of the Requirements for the Degree MASTER OF SCIENCE Major Subject: Biology West Texas A&M University Canyon, Texas December 2017 Approved: Rocky Ward, PhD Date Chairman, Thesis Committee W. David Sissom, PhD Date Member, Thesis Committee William P. Johnson, M.S. Date Member, Thesis Committee W. David Sissom, PhD Date Department Head Dean, Academic College Date Angela N. Spaulding Date Dean, Graduate School ii ABSTRACT The North American porcupine (Erethizon dorsatum) is a highly mobile, generalist species with an extensive geographical distribution in North America. The porcupine was first documented in southwestern Texas in the early 20th century, but today occurs in most of the western two-thirds of the state. This species is relatively unstudied within the Great Plains ecoregion of North America, with no genetic studies having been conducted for this species in Texas. The objectives of this study were to describe population genetic metrics of porcupines across 3 ecoregions in western Texas by examining variation in 17 polymorphic microsatellites, and to confirm the applicability of the zinc finger protein sequencing method to identify sex in a population of North American porcupines. Tissue samples from 106 porcupines were collected from the High Plains, Rolling Plains, and Edwards Plateau ecoregions of western Texas. Sex was accurately identified for 92 porcupine tissue samples by directly sequencing a short portion (195 base pairs) of the zinc finger protein gene. Sixteen base pair substitutions between Zfx and Zfy chromosomes denoted the sex of individuals; heterozygous sequence for males (Zfx and Zfy), homozygous sequence for females (Zfx only). -
The Beaver's Phylogenetic Lineage Illuminated by Retroposon Reads
www.nature.com/scientificreports OPEN The Beaver’s Phylogenetic Lineage Illuminated by Retroposon Reads Liliya Doronina1,*, Andreas Matzke1,*, Gennady Churakov1,2, Monika Stoll3, Andreas Huge3 & Jürgen Schmitz1 Received: 13 October 2016 Solving problematic phylogenetic relationships often requires high quality genome data. 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. -
Symposium on the Gray Squirrel
SYMPOSIUM ON THE GRAY SQUIRREL INTRODUCTION This symposium is an innovation in the regional meetings of professional game and fish personnel. When I was asked to serve as chairman of the Technical Game Sessions of the 13th Annual Conference of the Southeastern Association of Game and Fish Commissioners this seemed to be an excellent opportunity to collect most of the people who have done some research on the gray squirrel to exchange information and ideas and to summarize some of this work for the benefit of game managers and other biologists. Many of these people were not from the southeast and surprisingly not one of the panel mem bers is presenting a general resume of one aspect of squirrel biology with which he is most familiar. The gray squirrel is also important in Great Britain but because it causes extensive damage to forests. Much work has been done over there by Monica Shorten (Mrs. Vizoso) and a symposium on the gray squirrel would not be complete without her presence. A grant from the National Science Foundation through the American Institute of Biological Sciences made it possible to bring Mrs. Vizoso here. It is hoped that this symposium will set a precedent for other symposia at future wildlife conferences. VAGN FLYGER. THE RELATIONSHIPS OF THE GRAY SQUIRREL, SCIURUS CAROLINENSIS, TO ITS NEAREST RELATIVES By DR. ]. C. MOORE INTRODUCTION It seems at least slightly more probable at this point in our knowledge of the living Sciuridae, that the northeastern American gray squirrel's oldest known ancestors came from the Old \Vorld rather than evolved in the New. -

Mink: Wildlife Notebook Series
Mink The American mink (Neovison vison) and other fur bearing animals attracted trappers, traders, and settlers to Alaska from around the world. Some of the most valuable furbearers belong to the Mustelidae or weasel family, which includes the American mink. Other members of this family in Alaska include weasels, martens, wolverines, river otters, and sea otters. Mink are found in every part of the state with the exceptions of Kodiak Island, Aleutian Islands, the offshore islands of the Bering Sea, and most of the Arctic Slope. General description: A mink's fur is in prime condition when guard hairs are thickest. Mink are then a chocolate brown with some irregular white patches on the chin, throat, and belly. White patches are usually larger on females and often occur on the abdomen in the area of the mammary glands. Several albino mink have been reported from Alaska. Underfur is usually thick and wavy, not longer than an inch. It is dark gray to light brown in color with some suggestion of light and dark bands. The tail is one third to one fourth of the body length with slightly longer guard hairs than the body. As an adaptation to their aquatic lifestyle, their feet have semiwebbed toes and oily guard hairs tend to waterproof the animal. Adult males range in total length from 19 to 29 inches (48-74 cm). They may weigh from three to almost five pounds (1.4-2.3 kg). Females are somewhat smaller than males. Their movements are rapid and erratic as if they are always ready to either flee or pounce on an unwary victim. -

Eastern Gray Squirrel Survival in a Seasonally-Flooded Hunted Bottomland Forest Ecosystem
Squirrel Survival in a Flooded Ecosystem. Wilson et al. Eastern Gray Squirrel Survival in a Seasonally-Flooded Hunted Bottomland Forest Ecosystem Sarah B. Wilson, School of Forestry and Wildlife Sciences, Auburn University, 602 Duncan Dr. Auburn University, AL 36849 Stephen S. Ditchkoff, School of Forestry and Wildlife Sciences, Auburn University, 602 Duncan Dr. Auburn University, AL 36849 Robert A. Gitzen, School of Forestry and Wildlife Sciences, Auburn University, 602 Duncan Dr. Auburn University, AL 36849 Todd D. Steury, School of Forestry and Wildlife Sciences, Auburn University, 602 Duncan Dr. Auburn University, AL 36849 Abstract: Though the eastern gray squirrel (Sciurus carolinensis) is an important game species throughout its range in North America, little is known about environmental factors that may affect survival. We investigated survival and predation of a hunted population of eastern gray squirrels on Lown- des Wildlife Management Area in central Alabama from July 2015–April 2017. This area experiences annual flooding conditions from November through the following September. Our Kaplan-Meier survival estimate at 365 days for all squirrels was 0.25 (0.14–0.44, 95% CL) which is within the range for previously studied eastern gray squirrel populations (0.20–0.58). There was no difference between male (0.13; 0.05–0.36, 95% CL) and female survival (0.37; 0.18–0.75, 95% CL, P = 0.16). Survival was greatest in summer (1.00) and fall (0.65; 0.29–1.0, 95% CL) and lowest during winter (0.23; 0.11–0.50, 95% CL). We found squirrels were more likely to die during the flooded winter season and mortality risk increased as flood extent through- out the study area increased. -
Wildlife Species
Wildlife Species This chapter contains information on species featured in each of the ecoregions. Species are grouped by Birds, Mammals, Reptiles, Amphibians, and Fish. Species are listed alphabetically within each group. A general description, habitat requirements, and possible wildlife management practices are provided for each species. Wildlife management practices for a particular species may vary among ecoregions, so not all of the wildlife management practices listed for a species may be applicable for that species in all ecoregions. Refer to the WMP charts within a particular ecoregion to determine which practices are appropriate for species included in that ecoregion. The species descriptions contain all the information needed about a particular species for the WHEP contest. However, additional reading should be encouraged for participants that want more detailed information. Field guides to North American wildlife and fish are good sources for information and pictures of the species listed. There also are many Web sites available for wildlife species identification by sight and sound. Information from this section will be used in the Wildlife Challenge at the National Invitational. Participants should be familiar with the information presented within the species accounts for those species included within the ecoregions used at the Invitational. It is important to understand that when assessing habitat for a particular wildlife species and considering various WMPs for recommendation, current conditions should be evaluated. That is, WMPs should be recommended based on the current habitat conditions within the year. Also, it is important to realize the benefit of a WMP may not be realized soon. For example, trees or shrubs planted for mast may not provide cover or bear fruit for several years. -
Fort Riley Hunting Guide
FORT RILEY HUNTING GUIDE The Fort Riley Military Reservation is located in northeast Kansas between Manhattan and Junction City. About 71,000 of the installation's 101,000 acres are managed for multiple-use, including wildlife management. Hunting is allowed on Fort Riley when compatible with the post's primary mission of military training. Fort Riley has a diverse and abundant wildlife resource, which is a product of the post's good habitat conditions. Native tall-grass prairie is well interspersed with riparian and upland woodlands and shrublands creating diverse habitat conditions. Coupled with this native habitat is almost 1,600 acres of land leased for agricultural crop production on the installation's perimeter boundary. Another 700 acres of wildlife food plots, ranging in size from 1/2 to 15 acres, are planted in the interior of the Post each year. Nine principal game species are available to the Fort Riley hunter: bobwhite quail, ring-necked pheasant, greater prairie-chicken, mourning dove, wild turkey, white-tailed deer, elk, cottontail rabbit and fox squirrel. In addition to these species, good populations of raccoon, bobcat and coyote exist on Post. Waterfowl hunting opportunities can be fantastic along the rivers when the ponds and shallow water wetland areas start freezing over, as well as most Central Flyway "puddle" ducks can be found on Fort Riley's numerous ponds and lakes during the fall migration. REGULATIONS On Fort Riley, all State of Kansas and federal hunting regulations (bag limits, season lengths, hunting hours, methods of take, etc.) are in force unless otherwise noted in the Fort Riley Hunting and Fishing Regulations, FR Reg. -
