A phylogenetic analysis of VP2 gene sequences from puma, coyote, gray wolf, bobcat, raccoon, and striped skunk re- vealed two major groups related to either feline panleukopenia virus (“FPV-like”) or canine parvovirus (“CPV-like”). Cross- species transmission was commonplace, with multiple introductions into each host species but, with the exception of raccoons, relatively little evidence for onward transmission in nondomestic species. etermining how viruses infect and spread in new host species resulting in loss of the canine host range and altering neutralizing Dis central to the study of disease emergence (1, 2).

ABSTRACT: Tissue samples from an alleged Mexican Onza, shot in the western Sierra Madre in 1986, were subjected to several biochemical assays in an attempt to determine the specimen's relationship to felid species of North America. Protein analyses included isoenzyme electrophoresis and albumin isoelectric focusing. Mi- tochondrial DNA was assayed for restriction fragment lengths with 28 restriction enzymes, and the NÐ5 gene was sequenced. The resulting protein and rnitochondrial DNA characteristics of the Onza were indistinguishable from those of North Amer- ican pumas. INTRODUCTION In the Americas, there are two documented species of large cats: 1) Puma concolor, the puma, also called mountain lion, cougar, and panther in dif- ferent regions of North America, and known as leon in Mexico; and 2) Panthera onca, the jaguar, or tigre as it is known south of the U.S. border.

  • Spatial Characteristics of Residential Development Shift Large Carnivore Prey Habits
    The Journal of Wildlife Management; DOI: 10.1002/jwmg.21098 Research Article Spatial Characteristics of Residential Development Shift Large Carnivore Prey Habits JUSTINE A.

WILMERS, Department of Environmental Studies, Center for Integrated Spatial Research, University of California, Santa Cruz, 1156 High Street, Santa Cruz, CA 95064, USA ABSTRACT Understanding how anthropogenic development affects food webs is essential to implementing sustainable growth measures, yet little is known about how the spatial configuration of residential development affects the foraging behavior and prey habits of top predators. We examined the influence of the spatial characteristics of residential development on prey composition in the puma (Puma concolor). We located the prey remains of kills from 32 pumas fitted with global positioning system (GPS) satellite collars to determine the housing characteristics most influencing prey size and species composition. We examined how differences in housing density, proximity, and clustering influenced puma prey size and diversity. We found that at both local (150 m) and regional (1 km) spatial scales surrounding puma kill sites, housing density (but not the clustering of housing) was the greatest contributor to puma consumption of small prey (<20 kg), which primarily comprised human commensals or pets. The species-specific relationships between housing density and prey occupancy and detection rates assessed using camera traps were not always similar to those between housing density and proportions of diet, suggesting that pumas may exercise some diet selectivity.

One of the canids was a sub-adult captive maned wolf Chrysocyon brachyurus (Illiger, 1815), revealing skull damaged by canine tooth perforation and several bruises along the body. Examination of the wounds and the killing site provided reasonable details on how the attack was conducted. The mountain lion grabbed the maned wolf from behind with both forepaws, and killed it with a bite at the nape of the neck and at the back of the skull.

  • Cats of Belize Jaguar Average 4.25 Ft
    WEC314 A Guide to Living with Wild Cats1 Venetia S. Briggs-Gonzalez, Rebecca G. Harvey, Frank J. Mazzotti, and William M. Giuliano2 lands. This research suggests that more wild cats live near farms than people are aware of. Considering the number of wild cats living near villages, attacks on livestock and people are rare in Belize. However, conflicts between people and cats sometimes occur when cats lack food, water and habitat, when livestock is threat- ened, or when people are unaware of the benefits to living with cats. Cats of Belize Jaguar average 4.25 ft. long, 160 lbs. Figure 1. Jaguar (Panthera onca) Credits: © Tony Rath Photography, www.tonyrath.com Sharing the Landscape Belize is home to five species of wild cats. They live mainly in forests and wetlands, and hunt animals such as paca (gibnut), coatimundi, deer, peccary, birds, reptiles, and small rodents. When farms and villages are next to forests, people and wild cats live side-by-side.

  • Puma Field Guide, Available At
    In our on-going efforts to assist wildlife agencies, field researchers, and the general public, The Cougar Network is proud to present the Puma Identification Guide, developed with the help of leading wildlife biologists Harley Shaw, Paul Beier, Melanie Culver, and Melissa Grigione, and edited with the help of Chuck Anderson, Mark Dowling, Dave Hamilton, and Bob Wilson. This document is an abbreviated summary of guidelines used to identify Puma concolor. It discusses how the appearance, tracks, and kill sites of the puma differ from other species, which is not to say that other differentiators do not exist; scat size and segmentation might assist in determining a species in certain circumstances, but these differences are much more subtle and often require laboratory testing to confirm. The intent of this guide is to assist with the more concrete means of identifying the puma in the field. It is not intended to be used as a comprehensive guide to identifying the puma. This guide is not to be construed as a statement of policy; the document is provided only as a tool. This document does not discuss documenting identification. For more information on puma identification – along with information on biological considerations, life history, assessment, and management – see the full-length Puma Field Guide, available at www.cougarnet.org. Appearance Puma concolor has many names, including cougar, mountain lion, puma, catamount, panther and painter. A puma is a large, slender cat with a relatively small head, small, rounded ears that are not tufted, powerful shoulders and hindquarters, and a cylindrical tail that is long and heavy.

  • Jaguar and Puma Attacks on Livestock in Costa Rica
    Human–Wildlife Interactions 7(1):77–84, Spring 2013 Jaguar and puma attacks on livestock in Costa Rica RONIT AMIT1, Instituto Internacional en Conservación de Vida Silvestre, Universidad Nacional, Here- dia, Costa Rica [email protected] ELIAS JOSÉ GORDILLO-CHÁVEZ, División Académica de Ciencias Biológicas, Universidad Juárez Autónoma de Tabasco, México RAQUEL BONE, Escuela de Biología, Universidad de Costa Rica, San José, Costa Rica Abstract: Human–felid conflicts threaten long-term conservation of jaguars (Panthera onca) and pumas (Puma concolor). We interviewed ranchers from 50 ranches and inspected farms in northern Costa Rica that reported recent attacks on livestock by these 2 felids. We analyzed ranch characteristics, livestock management practices, details of predation, estimated market- value of economic losses, and ranchers’ perception of damage. Ranchers reported 81 felid attacks on livestock, including 60 head of cattle, 16 horses, 3 sheep, 1 pig, and 1 goat. Mean size of ranches was 233 km2, and mean livestock herd size was 109, including cattle, horses, pigs, sheep, goats, and water buffalo (Bubalus bubalis). Mean value of an attacked animal was U.S. $177.75 (range = $15 to $854, n = 51), and cumulative loss for all cattle was U.S. $9,065. Eighty-four percent of ranchers reported the presence of jaguars on their property, and 36% perceived the presence of pumas. Economic losses were overestimated by ranchers. Management strategies to address these problems must take into account the small size of ranches and limitations of the cattle and livestock production system in Costa Rica. Damage quantification based on market values can provide a guide to establish an incentive program, but provisions are needed due to ranchers’ potential discontent.

  • Mountain Lion Identification and Methods of Determining Sex and Age
    MOUNTAIN LION IDENTIFICATION AND METHODS OF DETERMINING SEX AND AGE Introduction South Dakota Game, Fish and Parks (SDGFP) is responsible for managing wildlife and its habitat as well as providing outdoor-related recreation. Our public outreach programs promote appreciation, understanding, and stewardship of South Dakota’s wildlife. SDGFP is funded through hunting and fishing license sales. The purpose of this document is to provide information to anyone who wants to hunt mountain lions and for anyone interested in mountain lion ecology. This document presents information about mountain lion biology, physiology, and behavior; explains how to determine the gender of a mountain lion; and details some of South Dakota’s laws and regulations pertaining to mountain lion hunting. Mountain Lions in South Dakota Mountain lions are native to the Black Hills of South Dakota. Dispersals outside of the Black Hills have been documented; however, there has been no evidence of an established prairie population. Mountain lions are efficient predators that primarily prey on deer and other small mammals In South Dakota their natural predators include other lions, disease, vehicles and humans. South Dakota State University and SDGFP have studied in the past, and continue to study a wide range of topics related to mountain lions in the Black Hills including home range size, survival, dispersal, population size, prey selection, survey methods, hunting impacts, and disease. Results of these studies continue to guide management activities for mountain lions in South Dakota and can be found at http://gfp.sd.gov/wildlife/management/research-projects/default.aspx. South Dakota Mountain Lion Hunting Regulations 1) No person may harvest or attempt to harvest a mountain lion with a spotted coat (kitten) or any mountain lion accompanying another mountain lion 2) No person may release dogs (where allowed) on tracks indicating multiple mountain lions traveling together.

The Pacific Northwest has experienced intensive logging during the past century and the distribution of martens in this region is largely discontinuous because of fragmented patches of forest cover (Gibilisco 1994). Based on state agency harvest data, the average annual number of martens harvested in the Oregon Cascades (and statewide) has decreased substantially during recent decades, but disentangling the potential factors (e.g., decreasing abundance, decreasing harvest effort) attributed to changes in harvest levels continues to prove difficult (Hiller 2011, Hiller et al.
