The Coati (Nasua nasua) is an exclusive species of South America, classified as vulnerable in some states of Brazil. In spite of its large distribution and importance, the data about its ultrasonographic anatomy was not found in the literature. The use of ultrasonographic examination in veterinary medicine is largely disseminated as a way of complementary diagnostic because it offers, as a non-invasive way, information about the organs anatomy and morphophysiology. Although ultrasonography is a largely disseminated complementary diagnostic method in the clinical routine of little animals, there are few accounts in wild animals. The aim of this study was to describe, in a comparative way, the ultrasonographic features and the topography anatomy of coatis liver, kidneys, adrenal glands, ovarian, pancreas, gastrointestinal tract, urinary vesicle, spleen and uterus, and establish reference values to measure the kidneys, urinary vesicle wall and the gastrointestinal tract, contributing in this way with scientific material to the ultrasonography learn in this species. It has been used seven adult and healthy coatis originating from the Wild Animals Selection Center WASC, in which it was realized scannings and transversal, longitudinal and coronal cuts of all the abdominal organs being studied. It was verified that the abdomen ultrasonographic examination of the coatis can be realized following the one that is advocated for the dog and for the cat. / O interesse pelo estudo de animais da fauna brasileira vem crescendo consideravelmente nos últimos anos, seja em decorrência do risco de extinção ou visando o controle de doenças, especialmente as zoonoses. O Quati (Nasua nasua) é uma espécie exclusiva da América do Sul, que está classificada como vulnerável em alguns estados do Brasil. Apesar de sua ampla distribuição e importância, dados sobre sua anatomia ultrassonográfica não foram encontrados na literatura. O emprego do exame ultrassonográfico na medicina veterinária é bastante difundido como meio de diagnóstico complementar, por fornecer de forma não invasiva informações sobre anatomia e morfofisiologia dos órgãos. Embora a ultrassonografia seja um método de diagnóstico complementar muito difundido na rotina clínica de pequenos animais, ainda são escassos os relatos em animais silvestres. O objetivo deste trabalho foi descrever, de forma comparativa, os aspectos ultrassonográficos e a anatomia topográfica do fígado, rins, glândulas adrenais, ovários, pâncreas, trato gastrintestinal, vesícula urinária, baço e útero dos quatis, e estabelecer valores de referência para as medidas de rins, parede da vesícula urinária e do trato grastintestinal, contribuindo assim, com material científico para aprendizado da ultrassonografia nesta espécie. Foram utilizados sete quatis adultos provenientes do Centro de Triagem de Animais Silvestres - CETAS, nos quais foram realizadas varreduras nos planos tranversais, sagitais e dorsais de todos os órgãos abdominais em estudo. Verificou-se que o exame ultrassonográfico do abdome dos quatis pode ser realizado seguindo o que está preconizado para o cão e o gato.

Knowledge about the use and behavioural relevance of the different senses in the South American Coati is limited. 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. In general, both adult males and non-males (here defined as adult females, as well as sub-adults and juveniles of both sexes) performed olfactory-related behaviors at similar frequencies. However, a few frequency differences for certain behaviors were found in the morning and in the afternoon, and in food or no food conditions, respectively. When food was present, for example, the coatis spent less time on olfactory-related foraging behaviors like “sniffing on ground” and “nose-digging” compared to when food was not present. The finding that scent-marking was rare in this captive group, indicates little need for territorial marking or communication of reproductive state under these circumstances. Findings from this study support the idea that Nasua nasua use their sense of smell in a variety of different contexts, and further studies are needed to extend the results.

The variables analyzed were: Heart rate (HR), rhythm, mean electrical axis (MEA), P wave, QRS complex, PR and QT interval, ST segment and T wave. Results showed: FC (157.62±28.22 bpm); P(0.058±0.021 mV and 0.03±0.0056 sec.); PR (0.07±0.0097 sec.); QRS (0.551±0.20 mV and 0.0335±0.0055 sec.); QT (0.165±0.017 sec.). Normal sinus rhythm was dominant (90.48%), however, animal one presented suggestive pattern of left anterior fascicle block. Two animals had sinus arrhythmia with wandering pacemaker (9.52%). The MEA varied from -30û a + 90û with a more frequent interval (90.48%) from +60û a +90û. The values observed for the coatis were similar to those of domestic cats (voltage and P-QRS complex) and domestic dogs (MEA). / Este trabalho teve por objetivo avaliar o perfil eletrocardiográfico de 21 quatis (Nasua nasua - Linnaeus, 1766) mantidos em cativeiro, sob contenção química utilizando quetamina e xilazina. Foram analisadas as variáveis: freqüência cardíaca (FC), ritmo, eixo elétrico médio (EEM) onda P, complexo QRS, intervalo PR e QT, segmento ST e onda T. Os resultados encontrados foram: FC (157,62±28,22 bpm); onda P (0,058±0,021 mV e 0,03±0,0056 seg); PR (0,07±0,0097 seg); QRS (0,551±0,20 mV e 0,0335±0,0055 seg); e QT (0,165±0,017 seg). O ritmo dominante foi o sinusal normal (90,48%), no entanto, um animal apresentou padrão sugestivo de bloqueio fascicular anterior esquerdo. Dois animais (9,52%) apresentaram arritmia sinusal com marcapasso migratório. O EEM variou de -30û a +90û, com 90,48% dos animais mostrando-se dentro do intervalo +60û a +90û. Os valores observados para os quatis foram similares aos do gato (mensurações e configurações do complexo P-QRS-T) e cão domésticos (EEM).

Dentro da família Procyonidae é uma das espécies com o repertório vocal mais extenso. N. narica e N. nelsoni são outras duas espécies do gênero Nasua. Nasua narica é nativo das Américas Central e do Norte e é conhecido por apresentar um focinho branco característico, Nasua nelsoni, espécie descrita recentemente, reside em ilhas mexicanas. Em 1960 algumas descrições qualitativas do repertório acústico desses animais tiveram início, trazendo informações importantes até a década de 80. Em 1998 foi descrito o repertório para N. narica, mas apenas em 2013 um primeiro estudo foi realizado com quatis N. nasua no Parque Ecológico do Tietê – SP, Brasil, a fim de descrever e contextualizar o repertório acústico da espécie de maneira mais detalhada. Objetivamos no presente estudo identificar as emissões vocais dos quatis e associar a contextos comportamentais exibidos em habitat natural. Além disso os parâmetros das emissões acústicas foram analisados. Um bando foi acompanhando durante suas atividades diárias de abril a setembro de 2014, no Parque Nacional da Serra dos Órgãos, sede Teresópolis, estado do Rio de Janeiro. Em Araras, distrito de Petrópolis-RJ, outro bando foi observado oportunisticamente durante um dia. O comportamento dos quatis foi registrado em arquivos de vídeo totalizando 100 minutos de gravação. Nesta pesquisa dezoito tipos de emissões vocais são descritos, juntamente com oito categorias comportamentais distintas (agonístico, brincadeira, busca, forrageio, locomoção, intimidação, investigação e separação) as quais estão associadas. Das dezoito emissões vocais uma não se restringe a uma única categoria comportamental (o assobio de contato), sendo cada categoria composta por no mínimo um tipo de chamado. Os chamados encontrados demonstram a riqueza do repertório acústico do quati, espécie abundante nos ecossistemas brasileiros e importante para estudos de comportamento e bioacústica. Esta pesquisa pode contribuir para sustentar planos de manejo para a conservação da espécie e dos seus habitats naturais. / Coatis Nasua nasua are gregarious mammals, that live in dense rainforests of South America and use the vocalization as an important method of communication. Within the Procyonidae family is one of the species with the most extensive vocal repertoire. N. narica and N. nelsoni are two other species of the genus Nasua. Nasua narica is native to the Central and Northern Americas and is known to have a characteristic white muzzle, Nasua nelsoni is a species recently described, lies in Mexican islands. In 1960 some qualitative descriptions of the acoustic repertoire of these animals began, bringing important information to the 80s in 1998 was described the repertoire for N. narica, but only in 2013 a first study was conducted with N. nasua coatis in the Ecological Park Tietê - SP, Brazil, in order to describe and contextualize the acoustic repertoire of the specie in more detail. We aimed in this study is identify the vocal emissions of coatis in behavioral contexts displayed in natural habitat. The parameters of acoustic emissions were analyzed. A group was watched during your daily activities from April to September 2014, on the National Park of the Organ Mountains, Teresopolis headquarters, State of Rio de Janeiro. On Araras, district of Petropolis, Rio de Janeiro, other group was observed opportunistically during a day. The behavior of coatis were recorded in video files totaling 100 minutes of recording. In this research eighteen types of vocal emissions are described, along with eight distinct behavioral categories (agonistic, play, search, foraging, locomotion, intimidation, research and separation) which are associated. One of the eighteen vocal emissions is not restricted to a single behavioral category (contact whistle) and each category being composed of at least one type of call. The so-called found demonstrate the richness of the acoustic repertoire of the coati, abundant species in Brazilian and important ecosystems for behavioral studies and bioacoustics. This research can contribute to support management plans for the conservation of the species and their natural habitats.

This experiment was conducted in two zoos - ZOO Troja in Prague and ZOO Ohrada in Hluboká nad Vltavou. The animals were presented the food enrichment of a puzzle type with different difficulties. Solving each levels of puzzles was being compared with the dominance of individuals in the group that was being observed by the aggression among all examinees. Nosal and their accession to the normal diet. All data were statistically evaluated. With the obtained results, the theory of "index of balance in the group" was tested.
