As a preservation and conservation strategy, specimens kept in captivity by Brazilian Institutions are monitored by a management plan. In order to characterize and analyze the genetic variability of Bush Dog specimens, a cytogenetic analysis was carried out, and microsatellite data were also obtained through the use of 15 primers, originally developed for the domestic Dog (Canis familiaris). All tested primers showed transferability and amplified fragment sizes similar to those described for the canine genome. From the total number of primers, eight were tested, and presented two polymorphic regions. Regarding cytogenetic analysis, one of the animals had chromosomal mosaicism, disqualifying it as a reproducer to form stocks. Thus, we concluded that the genetic evaluation of wild animals kept in captivity provides data that can help with the practice of exchange between different institutions, avoiding problems in the reproductive capacity of the breeding stock.The Bush Dog (Speothos venaticus) is a South American canid, included in the IBAMA (Brazilian Institute of Environment and Renewable Natural Resources) official list of animals threatened with extinction, in the vulnerable category.

Como estratégia de preservação e conservação, os espécimes mantidos em cativeiro por instituições brasileiras são acompanhados por um plano de manejo. Visando a caracterização genética e posterior análise de variabilidade genética de exemplares de cachorro-vinagre, foi feita a análise citogenética e testouse a transferabilidade de 15 primers de regiões microssatélites desenvolvidos para o cachorro doméstico (Canis familiaris) para esta espécie de canídeo. Todos os primers testados mostraram transferabilidade, com fragmentos amplificados de tamanhos semelhantes aos descritos para o genoma canino. Do total de primers, oito foram testados em 25 animais cativos e, dentre estes, duas regiões apresentaram polimórficas. Em relação à análise citogenética, um dos animais analisados apresentou mosaicismo cromossômico, desqualificando-o para utilização como reprodutor na formação de plantéis. Os demais exemplares apresentaram padrão cariotípicoesperado para a espécie. Desta forma, concluiu-se que a avaliação genética de animais silvestres criados em cativeiro fornece dados que podem auxiliar com a prática de intercâmbio entre animais de diferentes instituições, evitando o comprometimento na capacidade reprodutiva do plantel

A technique for attracting Bush Dogs Speothos venaticus in the wild
2015Co-Authors: Canid News, Karen E Dematteo, Osvaldo Carrillo, Gerald L. Zuercher, Silverio Ramírez, Kelli Smith, Ingrid J. PortonAbstract:The Bush Dog (Speothos venaticus) is a small unique canid whose distribution, ecology, and habitat requirements are poorly understood. This study, conducted in the Mbaracayú Re-serve, Paraguay, tested whether conspecific urine and vocalisations lured Bush Dogs to a specific location. Evidence (tracks, response vocalisations, physical disturbance, urine-marks, and faeces) suggests that the techniques used can serve as an important tool in gaining an understanding of this secretive canid within its natural habitat. The ability to attract Bush Dogs to a specific location would prove invalu-able for current and future researchers to com

fatal aortic aneurysm and rupture in a neotropical Bush Dog speothos venaticus caused by spirocerca lupi
Veterinary Parasitology, 2009Co-Authors: Miguel A Rinas, Raquel Nesnek, John M Kinsella, Karen E DematteoAbstract:This report details the post-mortem discovery of a larva of Spirocerca lupi in the caudal thoracic aorta of a 2-year, male Bush Dog (Speothos venaticus). This individual presented no clinical symptoms of the parasite's presence prior to its sudden death. The cause of death was determined to be acute bleeding following the rupture of an aneurysm in the caudal thoracic aorta as a result of the parasite located there. This is the first report of S. lupi in a Bush Dog.

How to distinguish between nouns and classifiers in Binominal Naming Constructions? Answers from two Western Amazonian languages
2017Co-Authors: An ,van Linden, Rose FrançoiseAbstract:Western Amazonian languages stand out in showing classifiers that – in addition to the well-established classifier environments – also appear as derivational devices on nouns (Payne 1987; Aikhenvald 2000; Seifart & Payne 2007). Since classifiers are commonly assumed to originate in nouns (Aikhenvald 2000), classifier languages confront us with an analytical problem in the domain of Binominal Naming Constructions (BNCs), i.e. how to distinguish between the derivational use of classifiers on nouns (1)-(2) and noun-noun compounds (3)-(4). The present paper addresses this problem on the basis of primary data collected on Harakmbut (isolate, Peru), e.g. (1) and (3), and Mojeño Trinitario (Arawak, Bolivia), e.g. (2) and (4), two unrelated (and not in contact) Western Amazonian languages. While Mojeño Trinitario will be shown to be a multiple classifier language with an extensive set of classifiers, Harakmbut turns out to show (a small set of) classifiers only, in fewer environments. Yet, both languages will appear to behave strikingly similarly in the domain of BNCs. (1) classifier-derived nouns in Harakmbut a) siro-pi metal-CLF:stick ‘knife’ (cf. Hart 1963: 1) b) siro-pu’ metal-CLF:cylindrical;hollow ‘metal tube’ (cf. Hart 1963: 1) (2) classifier-derived nouns in Mojeño Trinitario a) yuk(u)-pi fire-CLF:long;flexible ‘candle’ b) wray(u)-'a chicken-CLF:oval ‘chicken egg’ (3) noun-noun compounds in Harakmbut a) ndumba-kuwa forest-Dog ‘Bush Dog’ (Helberg 1984: 252; Tripp 1995: 194) b) äwït-ku giant.otter-head ‘giant otter’s head; person with giant otter’s head’ (4) noun-noun compounds in Mojeño Trinitario a) mari-chóchoku stone-river.bank ‘stony riverbank’ b) paku-miro Dog-face ‘Dog’s face; person with Dog’s face’ In this paper, we will discuss how noun-classifier derivation compares to noun-noun compounding at the phonological, prosodic, semantic and syntactic levels in both Harakmbut and Mojeño Trinitario. For example, noun-noun compounds consist of clear “Thing-roots” (Haspelmath 2012) in both languages, with one element being the morphosyntactic and semantic head. In noun-CLF formations, however, classifiers do not really denote a “thing”, but rather a shape or quality; they do not contain a head. As a factor bearing on this analytical problem, we will show that in both languages the noun/classifier distinction is blurred by the fact that there is a class of nouns that share many features with the canonical classifiers. In both languages, these nouns refer to parts of entities, such as bodyparts, cf. (3b) and (4b), or plant parts. Morphologically, these are bound roots, which require affixation to obtain independent nominal status, specifically possessor prefixes in Mojeño Trinitario and (semantically empty) nominalizing prefixes in Harakmbut. Interestingly, in both languages such N-N compounds as (3b) and (4b) can be used as endocentric compounds in their literal sense, but they can also be used exocentrically to refer to a person whose (physical) characteristics resemble those of the referent of the endocentric compound. In Mojeño Trinitario, such exocentric uses take determiners for human referents, whereas neither component noun refers to a human entity (Harakmbut lacks any formal indication for such uses). More generally, we will examine to what extent these bound nouns can be analysed as incipient classifiers, and formulate diachronic hypotheses informed by our analysis of BNCs.

Ixodofauna de animais silvestres e domésticos no estado de Santa Catarina
Universidade do Estado de Santa Catarina, 2012Co-Authors: Lavina, Marcia SangalettiAbstract:Os carrapatos são potenciais transmissores de patógenos causadores de doenças como a Febre Maculosa e Doença de Lyme ao homem, e da Erliquiose, Babesiose e Anaplasmose aos animais, entre outros. Sendo assim, o conhecimento a cerca da fauna de ixodídeos é de grande importância para o estabelecimento de programas de saúde pública e vigilância epidemiológica. Com o objetivo de identificar ixodídeos no estado de Santa Catarina foram examinados carrapatos de animais domésticos e silvestres que passaram pelo processo de triagem do Hospital de Clínicas Veterinárias do Centro de Ciências Agroveterinárias CAV/UDESC e de animais encontrados mortos em rodovias das seis mesorregiões do estado de Santa Catarina: Sul, Grande Florianópolis, Vale do Itajaí, Planalto Serrano, Norte e Oeste. Foi analisado ainda o material da coleção do Laboratório de Parasitologia e Doenças Parasitárias do CAV/UDESC. As identificações foram realizadas de acordo com as chaves dicotômicas de Aragão (1936) e Battesti et al. (2006). Na Região Sul foram identificadas Amblyomma aureolatum, A. ovale e Rhipicephalus (Boophilus) microplus parasitando cães, e uma amostra de A. longirostre encontrada sobre um homem. Na Região da Grande Florianópolis R. (B.) microplus, Rhipicephalus sanguineus, A. aureolatum e A. ovale parasitando cães; A. fuscum em furão (Mustela putorius) e R. (B.) microplus, A. cajennense e Anocentor nitens em equinos. No Planalto Serrano foram identificadas R. (B.) microplus, R. sanguineus, A. aureolatum, A. ovale, A. tigrinum e A. cajennense parasitando cães; A. aureolatum parasitando gato, graxaim (Cerdocyon thous), graxaim do campo (Pseudalopex gymnocercus), jaguatirica (Leopardus pardalis), cachorro do mato (Cerdocyon thous), leão baio (Puma concolor) e puma (Puma concolor); A. dubitatum em capivara (Hydrochoerus hydrochoeris); A. rotundatum em puma (Puma concolor) e cobra (Bohtrops); e R. (B.) microplus parasitando equino e veado (Mazama americana). Na Região Norte, R. sanguineus, A. aureolatum, A. ovale e A. tigrinum parasitando cães e A. nitens em equinos. No Vale do Itajaí foram identificados R. (B.) microplus, R. sanguineus, A. aureolatum, A. ovale e A. cajennense em cães; e A. cajennense e A. nitens em equinos. Amblyomma ovale e A. aureolatum em sapo (Bufo marinus); A. dubitatum em capivara e A. aureolatum em gato do mato (Leopardus tigrinus). Na região Oeste foram identificadas R. (B.) microplus, R. sanguineus e A. aureolatum em cães. Os bovinos foram excluídos do estudo por sabidamente sofrerem parasitismo por R. (B.) microplus em todo o Estado. Pelos dados obtidos constata-se uma ampla distribuição dos ixodídeos em todo o Estado e em diferentes hospedeiros, sendo as espécies A. cajennense, A. dubitatum, A. fuscum, A. longirostre e A. rotundatum identificadas pela primeira vez em Santa CatarinaTicks can transmit diseases causing pathogens such as the spotted fever and Lyme disease to humans and Ehrlichiosis, Babesiosis and Anaplasmosis to animals, among others. Thus the knowledge about the ixodid fauna is very important for establishing public health programs and epidemiological surveillance. In order to identify ticks in the state of Santa Catarina were examined ticks from domestic and wild animals that passed through the screening process of the Veterinary Clinical Hospital of the Center for Science Agroveterinary CAV/UDESC and animals found dead on the highways of six mesoregions of the state the Santa Catarina: Sul, Grande Florianópolis, Vale do Itajaí, Planalto Serrano, Norte and Oeste. It also analyzed the material from the collection of the Laboratory of Parasitology and Parasitic Diseases of the CAV/UDESC. The identifications were made according to the dichotomous keys of Aragão (1936) and Battesti et al. (2006). In the Sul region were identified Amblyomma aureolatum, A. ovale and Rhipicephalus (Boophilus) microplus parasitizing Dogs, and a sample of A. longirostre found on a man. In the Grande Florianópolis R. (B.) microplus, Rhipicephalus sanguineus, A. aureolatum and A. ovale parasite of Dogs; A. fuscum in ferret (Mustela putorius) and R. (B.) microplus, A. cajennense and Anocentor nitens in horses. Were identified in the Planalto Serrano R. (B.) microplus, R. sanguineus, A. aureolatum, A. ovale, A. tigrinum and A. cajennense parasitizing Dogs, A. aureolatum parasitizing cat, graxaim (Cerdocyon thous), graxaim field (Pseudalopex gymnocercus), ocelot (Leopardus pardalis), Bush Dog (Cerdocyon thous), lion bay (Puma concolor) and puma (Puma concolor), A. dubitatum a capybara (Hydrochoerus hydrochoeris), A. rotundatum in puma (Puma concolor) and snake (Bohtrops) and R. (B.) microplus parasitizing deer (Mazama americana) and horse. In the Norte Region R. sanguineus, A. aureolatum, A. ovale and A. tigrinum parasitizing Dogs, A. nitens in horses. In Vale do Itajaí have been identified R. (B.) microplus, R. sanguineus, A. aureolatum, A. ovale and A. cajennense in Dogs, and A. cajennense and A. nitens in horses. Amblyomma ovale and A. aureolatum into a frog (Bufo marinus); A. dubitatum a capybara and A. aureolatum in wild cat (Leopardus tigrinus). In the Oeste region were identified R. (B.) microplus, R. sanguineus and A. aureolatum in Dogs. The cattle were excluded from the study are known to suffer parasitism by R. (B.) microplus throughout the state. From the data obtained it appears a wide distribution of ixodid throughout the state and in different hosts and the species A. cajennense, A. dubitatum, A. fuscum, A. longirostre e A. rotundatum were identified by the first time ever in Santa Catarin

(B.) microplus parasitizing deer (Mazama americana) and horse. In the Norte Region R. sanguineus, A. aureolatum, A. ovale and A. tigrinum parasitizing Dogs, A. nitens in horses. In Vale do Itajaí have been identified R. (B.) microplus, R. sanguineus, A. aureolatum, A. ovale and A. cajennense in Dogs, and A. cajennense and A. nitens in horses. Amblyomma ovale and A. aureolatum into a frog (Bufo marinus); A. dubitatum a capybara and A. aureolatum in wild cat (Leopardus tigrinus). In the Oeste region were identified R. (B.) microplus, R. sanguineus and A. aureolatum in Dogs. The cattle were excluded from the study are known to suffer parasitism by R. (B.) microplus throughout the state. From the data obtained it appears a wide distribution of ixodid throughout the state and in different hosts and the species A. cajennense, A. dubitatum, A. fuscum, A. longirostre e A. rotundatum were identified by the first time ever in Santa CatarinaOs carrapatos são potenciais transmissores de patógenos causadores de doenças como a Febre Maculosa e Doença de Lyme ao homem, e da Erliquiose, Babesiose e Anaplasmose aos animais, entre outros. Sendo assim, o conhecimento a cerca da fauna de ixodídeos é de grande importância para o estabelecimento de programas de saúde pública e vigilância epidemiológica. Com o objetivo de identificar ixodídeos no estado de Santa Catarina foram examinados carrapatos de animais domésticos e silvestres que passaram pelo processo de triagem do Hospital de Clínicas Veterinárias do Centro de Ciências Agroveterinárias CAV/UDESC e de animais encontrados mortos em rodovias das seis mesorregiões do estado de Santa Catarina: Sul, Grande Florianópolis, Vale do Itajaí, Planalto Serrano, Norte e Oeste. Foi analisado ainda o material da coleção do Laboratório de Parasitologia e Doenças Parasitárias do CAV/UDESC. As identificações foram realizadas de acordo com as chaves dicotômicas de Aragão (1936) e Battesti et al. (2006). Na Região Sul foram identificadas Amblyomma aureolatum, A. ovale e Rhipicephalus (Boophilus) microplus parasitando cães, e uma amostra de A. longirostre encontrada sobre um homem. Na Região da Grande Florianópolis R. (B.) microplus, Rhipicephalus sanguineus, A. aureolatum e A. ovale parasitando cães; A. fuscum em furão (Mustela putorius) e R. (B.) microplus, A. cajennense e Anocentor nitens em equinos. No Planalto Serrano foram identificadas R. (B.) microplus, R. sanguineus, A. aureolatum, A. ovale, A. tigrinum e A. cajennense parasitando cães; A. aureolatum parasitando gato, graxaim (Cerdocyon thous), graxaim do campo (Pseudalopex gymnocercus), jaguatirica (Leopardus pardalis), cachorro do mato (Cerdocyon thous), leão baio (Puma concolor) e puma (Puma concolor); A. dubitatum em capivara (Hydrochoerus hydrochoeris); A. rotundatum em puma (Puma concolor) e cobra (Bohtrops); e R. (B.) microplus parasitando equino e veado (Mazama americana). Na Região Norte, R. sanguineus, A. aureolatum, A. ovale e A. tigrinum parasitando cães e A. nitens em equinos. No Vale do Itajaí foram identificados R. (B.) microplus, R. sanguineus, A. aureolatum, A. ovale e A. cajennense em cães; e A. cajennense e A. nitens em equinos. Amblyomma ovale e A. aureolatum em sapo (Bufo marinus); A. dubitatum em capivara e A. aureolatum em gato do mato (Leopardus tigrinus). Na região Oeste foram identificadas R. (B.) microplus, R. sanguineus e A. aureolatum em cães. Os bovinos foram excluídos do estudo por sabidamente sofrerem parasitismo por R. (B.) microplus em todo o Estado. Pelos dados obtidos constata-se uma ampla distribuição dos ixodídeos em todo o Estado e em diferentes hospedeiros, sendo as espécies A. cajennense, A. dubitatum, A. fuscum, A. longirostre e A. rotundatum identificadas pela primeira vez em Santa CatarinaCoordenação de Aperfeiçoamento de Pessoal de Nível Superio

MOLECULAR SYSTEMATICS OF THE CANIDAE
2016Co-Authors: Lisa M. Lau, Charles R. MarshallAbstract:Abstract.—Despite numerous systematic studies, the relationships among many species within the Dog family, Canidae, remain unresolved. Two problems of broad evolutionary significance are the origins of the taxonomically rich canid fauna of South America and the development in three species of the trenchant heel, a unique meat-cutting blade on the lower first molar. The first problem is of interest because the fossil record provides little evidence for the origins of divergent South American species such as the maned wolf and the Bush Dog. The second issue is problematic because the trenchant heel, although complex in form, may have evolved independently to assist in the processing of meat. We attempted to resolve these two issues and five other specific taxo-nomic controversies by phylogenetic analysis of 2,001 base pairs of mitochondrial DNA (mtDNA) sequence data from 23 canid species. The mtDNA tree topology, coupled with data from the fossil record, and estimates of rates of DNA sequence divergence suggest at least three and possibly four North American invasions of South America. This result implies that an important chapter in the evolution of modern canids remains to be discovered in the fossil record and that the South American canid endemism is as much the result of extinction outside of South America as it is due to speciation within South America. The origin of the trenchant heel is not well resolved b

The origin of the trenchant heel is not well resolved by our data, although the maximum parsimony tree is weakly consistent with a single origin followed by multiple losses of the character in several extant species. A combined analysis of the mtDNA data and published morphological data provides unexpected support for a monophyletic South American canid clade. However, the homogeneity partition tests indicate significant heterogeneity between the two data sets. (Canidae; combined analysis; mtDNA; phylogeny; South America; trenchant heel.)
