Path. 2019, Vol. 167, 60e72 Available online at www.sciencedirect.com ScienceDirect www.elsevier.com/locate/jcpa DISEASE IN WILDLIFE OR EXOTIC SPECIES Dental and Temporomandibular Joint Pathology of the Kit Fox (Vulpes macrotis) N. Yanagisawa*, R. E. Wilson*, P. H. Kass† and F. J. M. Verstraete* *Department of Surgical and Radiological Sciences and † Department of Population Health and Reproduction, School of Veterinary Medicine, University of California, Davis, California, USA Summary Skull specimens from 836 kit foxes (Vulpes macrotis) were examined macroscopically according to predefined criteria; 559 specimens were included in this study. The study group consisted of 248 (44.4%) females, 267 (47.8%) males and 44 (7.9%) specimens of unknown sex; 128 (22.9%) skulls were from young adults and 431 (77.1%) were from adults. Of the 23,478 possible teeth, 21,883 teeth (93.2%) were present for examina- tion, 45 (1.9%) were absent congenitally, 405 (1.7%) were acquired losses and 1,145 (4.9%) were missing ar- tefactually. No persistent deciduous teeth were observed. Eight (0.04%) supernumerary teeth were found in seven (1.3%) specimens and 13 (0.06%) teeth from 12 (2.1%) specimens were malformed. Root number vari- ation was present in 20.3% (403/1,984) of the present maxillary and mandibular first premolar teeth. Eleven (2.0%) foxes had lesions consistent with enamel hypoplasia and 77 (13.8%) had fenestrations in the maxillary alveolar bone. Periodontitis and attrition/abrasion affected the majority of foxes (71.6% and 90.5%, respec- tively). -

Notes on the Distribution, Status, and Research Priorities of Little-Known Small Carnivores in Brazil
Notes on the distribution, status, and research priorities of little-known small carnivores in Brazil Tadeu G. de OLIVEIRA Abstract Ten species of small carnivores occur in Brazil, including four procyonids, four mustelids (excluding otters), and two mephitids. On the IUCN Red List of Threatened Species eight are assessed as Least Concern and two as Data Deficient. The state of knowledge of small carnivores is low compared to other carnivores: they are among the least known of all mammals in Brazil. The current delineation of Bassaricyon and Galictis congeners appears suspect and not based on credible information. Research needs include understanding dis- tributions, ecology and significant evolutionary units, with emphasis on theAmazon Weasel Mustela africana. Keywords: Amazon weasel, Data Deficient, Olingo, Crab-eating Raccoon, Hog-nosed Skunk Notas sobre la distribución, estado y prioridades de investigación de los pequeños carnívoros de Brasil Resumen En Brasil ocurren diez especies de pequeños carnívoros, incluyendo cuatro prociónidos, cuatro mustélidos (excluyendo nutrias) y dos mephitidos. De acuerdo a la Lista Roja de Especies Amenazadas de la UICN, ocho especies son evaluadas como de Baja Preocupación (LC) y dos son consideradas Deficientes de Datos (DD). El estado de conocimiento de los pequeños carnívoros es bajo comparado con otros carnívoros y se encuentran entre los mamíferos menos conocidos de Brasil. La delineación congenérica actual de Bassaricyon y Galictis parece sospechosa y no basada en información confiable.

The 2008 IUCN Red Listings of the World's Small Carnivores
The 2008 IUCN red listings of the world’s small carnivores Jan SCHIPPER¹*, Michael HOFFMANN¹, J. W. DUCKWORTH² and James CONROY³ Abstract The global conservation status of all the world’s mammals was assessed for the 2008 IUCN Red List. Of the 165 species of small carni- vores recognised during the process, two are Extinct (EX), one is Critically Endangered (CR), ten are Endangered (EN), 22 Vulnerable (VU), ten Near Threatened (NT), 15 Data Deficient (DD) and 105 Least Concern. Thus, 22% of the species for which a category was assigned other than DD were assessed as threatened (i.e. CR, EN or VU), as against 25% for mammals as a whole. Among otters, seven (58%) of the 12 species for which a category was assigned were identified as threatened. This reflects their attachment to rivers and other waterbodies, and heavy trade-driven hunting. The IUCN Red List species accounts are living documents to be updated annually, and further information to refine listings is welcome.

Surra Importance Surra, Caused by Trypanosoma Evansi, Is One of the Most Important Diseases of Animals in Tropical and Semitropical Regions
Surra Importance Surra, caused by Trypanosoma evansi, is one of the most important diseases of animals in tropical and semitropical regions. While surra is particularly serious in Murrina, Mal de Caderas, equids and camels, infections and clinical cases have been reported in most Derrengadera, Trypanosomosis, domesticated mammals and some wild species. T. evansi is transmitted mechanically El Debab, El Gafar, Tabourit by various tabanids and other flies, and it can readily become endemic when introduced into a new area. The morbidity and mortality rates in a population with no immunity can be high. In the early 1900s, an outbreak in Mauritius killed almost all Last Updated: September 2015 of the Equidae on the island. More recently, severe outbreaks have been reported in the Philippines, Indonesia and Vietnam. In addition to illness and deaths, surra causes economic losses from decreased productivity in working animals, reduced weight gain, decreased milk yield, reproductive losses and the cost of treatment. Etiology Surra is caused by the protozoal parasite Trypanosoma evansi. This organism belongs to the subgenus Trypanozoon and the Salivarian section of the genus Trypanosoma. Two genetic types of T. evansi, type A and type B, have been recognized. Most isolates worldwide belong to type A. Type B, which is not recognized by some diagnostic tests, has only been detected in parts of Africa as of 2015. Whether T. evansi should be considered a distinct species, separate from T. brucei, is controversial. Species Affected The principal hosts and reservoirs for T. evansi are reported to differ between regions; however, camels, equids, water buffalo and cattle are generally considered to be the major hosts among domesticated animals. -

The aim of the present study was therefore to investigate the use of the sense of smell in this species. Twenty-five captive coatis were observed at the zoo of La Paz for a total of 120 hours to collect data on olfactory-related behaviors. The coatis frequently performed behaviors in response to the detection of odors such as sniffing on the ground, on objects, on food, on conspecifics, or in the air. In contrast, they did not display many odor depositing behaviors such as urinating, defecating, or scent-marking. The most frequently performed olfactory-related behavior was “sniffing on ground” which accounted for an average of 40 % of all recorded behaviors. -

Cladistic analyses of morpho- logical characters conducted during the last two decades have resulted in topologies that group ecologically and morphologically similar taxa together. SpeciWcally, the highly arboreal and frugivorous kinkajou (Potos Xavus) and olingos (Bassaricyon) deWne one clade, whereas the more terrestrial and omnivorous coatis (Nasua), raccoons (Procyon), and ringtails (Bassariscus) deWne another clade, with the similar-sized Nasua and Procyon joined as sister taxa in this latter group. These relationships, however, have not been tested with molecu- lar sequence data. We examined procyonid phylogenetics based on combined data from nine nuclear and two mitochondrial gene seg- ments totaling 6534 bp. -
Jaguars As Landscape Detectives for the Conservation of Atlantic Forests in Brazil
Jaguars as Landscape Detectives for the Conservation of Atlantic Forests in Brazil by Laury Cullen Jr. Thesis submitted for the degree of Doctor of Philosophy Biodiversity Management Durrell Institute of Conservation and Ecology (DICE) University of Kent Canterbury November 2006 ii Dedication In dedication to the loving memory of my father Laury Cullen (1934-2002) (Photo by Laury Cullen Jr.) “ the jaguar was sent to the world as a test of the will and integrity of first humans” (Colombian indigenous myth, Davis 1996) iii Abstract In this thesis, I show how the jaguar Panthera onca can be used as a landscape detective. A landscape detective is defined as a species that helps determine how to manage landscapes and to design and manage protected area networks. Life history and behavioural features of jaguar make them potentially suitable as landscape species. The main aim of this study is to use the jaguar as a landscape detective to develop a network of core protected areas for the Upper Paraná Region, which lies in the highly threatened Atlantic Forest of Brazil. Information was collected on jaguar density and home range, which was combined with habitat requirements of the species and GIS-generated maps of land cover to develop a map of habitat suitability. This map was used to understand the spatial structure of the jaguar metapopulation, identifying habitat patches of high suitability where jaguar populations exist and are likely to survive over the long-term. Camera trapping and capture-recapture models were used to derive jaguar population size in Morro do Diabo State Park (MDSP).
