Respiratory Turbinates of Canids and Felids: a Quantitative Comparison
J. Zool., Lond. (2004) 264, 281–293 C 2004 The Zoological Society of London Printed in the United Kingdom DOI:10.1017/S0952836904005771 Respiratory turbinates of canids and felids: a quantitative comparison Blaire Van Valkenburgh1*, Jessica Theodor 2, Anthony Friscia1, Ari Pollack1 and Timothy Rowe3 1 Department of Ecology and Evolutionary Biology, University of California, Los Angeles, CA 90095-1606, U.S.A. 2 Department of Geology, Illinois State Museum, 1011 East Ash Street, Springfield, IL 62703, U.S.A. 3 Department of Geological Sciences, University of Texas, Austin, TX 78712, U.S.A. (Accepted 31 March 2004) Abstract The respiratory turbinates of mammals are complex bony plates within the nasal chamber that are covered with moist epithelium and provide an extensive surface area for the exchange of heat and water. Given their functional importance, maxilloturbinate size and structure are expected to vary predictably among species adapted to different environments. Here the first quantitative analysis is provided of maxilloturbinate structure based on high-resolution computed tomography (CT) scans of the skulls of eight canid and seven felid species. The key parameters examined were the density of the maxilloturbinate bones within the nasal chamber and how that density varied along the air pathway. In both canids and felids, total maxilloturbinate chamber volume and bone volume increased with body size, with canids having c. 1.5–2.0 times the volume of maxilloturbinate than felids of similar size. In all species, the volume of the maxilloturbinates varies from rostral to caudal, with the peak volume occurring approximately midway, close to where airway cross-sectional area is greatest. -

Today, people can purchase these garments in many stores all over the world. 20 5 Changing Colors with the Seasons The fur of some Arctic animals changes from the woodland colors of the fall to pure white like winter snow. If they kept their woodland colors, these Arctic animals would stand out in the white snow and they would be unprotected. So, their fur must change to white. As a result, the animals can hide in the snow from their enemies and search safely for food. -
Appendix Lagomorph Species: Geographical Distribution and Conservation Status
Appendix Lagomorph Species: Geographical Distribution and Conservation Status PAULO C. ALVES1* AND KLAUS HACKLÄNDER2 Lagomorph taxonomy is traditionally controversy, and as a consequence the number of species varies according to different publications. Although this can be due to the conservative characteristic of some morphological and genetic traits, like general shape and number of chromosomes, the scarce knowledge on several species is probably the main reason for this controversy. Also, some species have been discovered only recently, and from others we miss any information since they have been first described (mainly in pikas). We struggled with this difficulty during the work on this book, and decide to include a list of lagomorph species (Table 1). As a reference, we used the recent list published by Hoffmann and Smith (2005) in the “Mammals of the world” (Wilson and Reeder, 2005). However, to make an updated list, we include some significant published data (Friedmann and Daly 2004) and the contribu- tions and comments of some lagomorph specialist, namely Andrew Smith, John Litvaitis, Terrence Robinson, Andrew Smith, Franz Suchentrunk, and from the Mexican lagomorph association, AMCELA. We also include sum- mary information about the geographical range of all species and the current IUCN conservation status. Inevitably, this list still contains some incorrect information. However, a permanently updated lagomorph list will be pro- vided via the World Lagomorph Society (www.worldlagomorphsociety.org). 1 CIBIO, Centro de Investigaça˜o em Biodiversidade e Recursos Genéticos and Faculdade de Ciˆencias, Universidade do Porto, Campus Agrário de Vaira˜o 4485-661 – Vaira˜o, Portugal 2 Institute of Wildlife Biology and Game Management, University of Natural Resources and Applied Life Sciences, Gregor-Mendel-Str. -

Phylogeography and Historical Demographics of Lepus Arcticus, L

COOK† *Department of Biological Sciences, Idaho State University, Pocatello, ID 83209-8007, USA, †Museum of Southwestern Biology & Department of Biology, University of New Mexico, Albuquerque, NM 87131-0001, USA Abstract Phylogeographical investigations of arctic organisms provide spatial and temporal frameworks for interpreting the role of climate change on biotic diversity in high-latitude ecosystems. Phylogenetic analyses were conducted on 473 base pairs of the mitochondrial control region in 192 arctic hares (Lepus arcticus, Lepus othus, Lepus timidus) and two individual Lepus townsendii. The three arctic hare species are closely related. All L. othus indi- viduals form one well-supported clade, L. arcticus individuals form two well-supported clades, and L. timidus individuals are scattered throughout the phylogeny. Arctic hare distribution was altered dramatically following post-Pleistocene recession of continental ice sheets. We tested for genetic signatures of population expansion for hare populations now found in deglaci- ated areas. Historical demographic estimates for 12 arctic hare populations from throughout their range indicate that L. arcticus and L. othus persisted in two separate North American arctic refugia (Beringia and High Canadian Arctic) during glacial advances of the Pleistocene, while the high genetic diversity in L. timidus likely reflects multiple Eurasian refugia.

Arctic Hare (Lepus Arcticus Bangsii)
The Status of Arctic Hare (Lepus arcticus bangsii) in Insular Newfoundland © Steve Sayles THE SPECIES STATUS ADVISORY COMMITTEE REPORT NO. 26 February 20, 2012 RECOMMENDED STATUS Recommended status: Current designation: DATA DEFICIENT None Criteria met: Data Deficient Reasons for designation: Uncertain taxonomic distinction Unknown area of occupancy Uncertain number of extant locations Unknown trend in number of locations Unknown habitat trend Uncertain population size Unknown population size trend Unknown if extreme population size fluctuations (>1 order of magnitude) This report was originally prepared by Brian Hearn and subsequently edited by the Species Status Advisory Committee. 2 STATUS REPORT Lepus arcticus bangsii (Rhoads, 1896) Arctic hare (Newfoundland population) lièvre arctique, Ukaliq Family: Leporidae (Hares and Rabbits) Life Form: Mammal Systematic/Taxonomic Clarifications This report examines the arctic hare population on the island of Newfoundland, a population within the subspecies Lepus arcticus bangsii, as a discrete and evolutionarily significant designatable unit because of its geographic and presumed reproductive isolation and its distinction as the southernmost population of arctic hare in North America. The taxonomy of the arctic or northern hare group(s) is disputed. Presently, three species of arctic (northern) hare are recognized: the Arctic hare (Lepus arcticus) occupying the tundra regions of Canada and along the coastal regions of Greenland; the Alaskan hare (Lepus othus) which is restricted to the western and northwestern regions of Alaska; and the Mountain hare (Lepus timidus) which is found throughout most of the Palaearctic region from Great Britain and Fennoscandia to eastern Siberia (Figure 1). Not surprisingly, the taxonomic status of these three species has been a long-standing controversy (Hall 1951, Best and Henry 1994). -
Raccoon Dog Misrepresentation Continues Investigation Results: Fall/Winter 2007
Raccoon Dog Misrepresentation Continues Investigation Results: Fall/Winter 2007 Published March 18, 2008 Summary In the fall and winter of 2007, investigators from The Humane Society of the United States (HSUS) purchased and tested fur-trimmed jackets from some of the largest names in fashion. Seven jackets were found to contain real fur despite being advertised or labeled as faux fur, and these results were publicized on December 20, 2007. An additional six jackets— detailed in the chart below—were found to be falsely advertised or mislabeled as the wrong species—or simply as “fur.” Retailers and brand names associated with these jackets include Sears, Bluefly, Dillard’s, Eluxury.com, Caché, Dr. Jay’s, and Juicy Couture. Four of the jackets contain raccoon dog fur. Background December 2007: The HSUS publicizes findings that seven fur-trimmed garments purchased from major retailers, and advertised or labeled as faux fur, in fact contain real fur from raccoon dogs, raccoons, or rabbits. Retailers and brand names associated with these jackets include Saks Fifth Avenue, Dillard’s, Andrew Marc, Lord & Taylor, Neiman Marcus and Burberry. March 2007: Andrew Marc, Dillard’s, Lord & Taylor, Neiman Marcus, Macy’s, and seven other major retailers and designers were named by The HSUS in a petition filed before the Federal Trade Commission (FTC) seeking enforcement actions for violations of the Fur Products Labeling Act. The petition remains pending before the FTC. February 2007: The Dog and Cat Fur Prohibition Enforcement Act—H.R. 891—is introduced by Reps. Jim Moran (D- Va.) and Michael Ferguson (R-N.J.). -

Red Fox: Wildlife Notebook Series
Red Fox The red fox (Vulpes vulpes), is the subject of many stories, songs, fables, and parables. Its flashy good looks and its ability to live close to people and their varied activities have undoubtedly contributed to this notoriety. Probably a more important reason is the fox's reputation for cunning and intelligence. Several English expressions testify to the fox's wily mind: “sly as a fox,” “foxy,” “outfoxed,” and “crazy as a fox.” Actually, the red fox has well developed senses of sight, smell, and hearing, which are responsible for much of its reputation. Distribution: The red fox is common in most of northern North America. It is found throughout Alaska, except for some of the islands of Southeast Alaska and the western Aleutians and is rare in Prince William Sound. It is native to Kodiak Island but is an introduced animal on many islands in the state as a result of fox farming operations in the early 1900s. Red fox populations in Southeast Alaska are sparse, but the animal is found in the Taku and Stikine river valleys and the Mendenhall Flats. Red foxes have also been seen on Douglas Island near Juneau. The fox prefers broken country, extensive lowland marshes, and crisscrossed hills and draws. It is most abundant south of the arctic tundra. It is also present in tundra regions, which it shares with the Arctic fox. Where the ranges of the two species overlap, the red fox is dominant. In these areas, red foxes have been observed digging white (Arctic) foxes from their dens and killing them. -
Arctic Wolf Scientific Name: Canis Lupus Arctos the Arctic Wolf Is a Medium to Large, Mostly-White, Wolf Inhabiting North America North of About 60 Degrees N
species factsheet | species introduction | Common name: Arctic wolf Scientific name: Canis lupus arctos The Arctic wolf is a medium to large, mostly-white, wolf inhabiting North America north of about 60 degrees N. latitude and the north-eastern, northern, and north-western shore of Greenland. It intergrades with other wolf races south of it. It preys on muskoxen, Arctic hares and caribou and can live in packs of up to at least 20 animals. Arctic wolves in Québec:© Eric Pépin http://www.flickr.com/photos/zorro-the-cat/2341125207/ | status in the wild | The population status is secure. Although Arctic wolves are hunted and trapped primarily by Inuit and other native people the species is not threatened. | species reproduction | These wolves mate in late March and early April. Gestation period is 63 days, and pups are pups born late May to early June. They den in rock caves, shallow pits, holes, enlarged fox dens, etc. Litter size up to 6. Both parents care for and feed the pups, as do yearling and older sibling helpers. | species habitat | Habitat is taiga, tundra and barren grounds | species food | Preys primarily on muskoxen, Arctic hares, caribou, seals, but like all other wolves opportunistically eats all other types of vertebrates available. | threats | Although hunted and trapped primarily by Inuit and other native people the population status is secure. No known long-term or general climate-change threat, although local climatic conditions can adversely affect local populations temporarily. | conservation | Various Canadian provinces and territories regulate harvesting to varying degrees, but human density in the Arctic wolf’s range is low enough that populations are secure so long as fur prices do not increase considerably.
