Resumo A etologia dos insetos é um fator importante quando se deseja relizar manejo de pragas. Através deste conhecimento, é possível manipular atividades comportamentais, repelir, ou atrair os insetos de acordo com as necessidades e interesses. O gorgulho do milho Sitophilus zeamais (Mots., 1855) (Coleoptera: Curculionidae), uma das principais pragas de grãos armazenados tem sido alvo de estudos de alterações comportamentais através de substâncias naturais devido à sua resistência a diferentes classes de insecticidas. Assim, este estudo teve como objetivo avaliar o efeito de concentrações subletais de extrato de neem e do óleo de copaíba sobre o comportamento de movimentação de S. zeamais. As características comportamentais consideradas foram: a atividade de caminhamento, a frequência do contato dos insetos com a massa de grãos tratada, e o tempo gasto para realização destes comportamentos. A atividade de caminhamento do S. zeamais aumentou quando os insetos foram expostos ao extrato de Neem e ao óleo de copaíba. Em geral, o extrato de Neem e o óleo de Copaíba induziram mais contato com a massa de grãos do que o controle, sugerindo um efeito atrativo sobre o inseto, contudo este efeito foi mais significativo para o óleo de Neem. O comportamento do inseto foi alterado, apresentando um caminhamento específico devido aos estímulos do óleo de copaíba e do extrato de Neem. Estes resultados indicam que o óleo de copaíba e o extrato de Neem podem ser alternativas potenciais para o controle do S. zeamais em produtos armazenados, uma vez que alterações no comportamento desta praga podem reduzir os danos qualitativos e quantitativos nos grãos. Assim, o desenvolvimento de produtos baseados no óleo de copaíba e no extrato de Neem pode ser útil para o manejo de pragas de armazenamento.

Abstract Insects' ethology is an important factor when it is desired to carry out pest management. This knowledge makes it possible to manipulate behavioral activities, repel, or attract insects according to needs and interests. The maize weevil Sitophilus zeamais (Mots., 1855) (Coleoptera: Curculionidae), one of the main stored grain pests, has been the target of studies of behavioral changes studies through natural substances due to its resistance to different insecticidal classes. Thus, this study aimed to evaluate the effect of sublethal concentrations of neem extract and copaiba oil on the locomotor behavior of S. zeamais. The behavioral characteristic considered were walking activity, the frequency of contact of insects with the treated grain mass, and the time spent for this behavior. The walking activity of the S. zeamais increased with exposure to Neem extract and Copaiba oil. In general, the Neem extract and Copaiba oil-induced more contact with grain mass than the control, suggesting an attractive effect on the insect, however more significant for the Neem oil. The insect's behavior was altered, presenting a specific path due to Copaiba oil and Neem extract stimuli. These results indicate that Copaiba oil and Neem extract can be a potential alternative for controlling S. zeamais on stored products since changes in this pests' behavior can reduce qualitative and quantitative grain damage. Thus, the development of products based on Copaiba oil and Neem extract may be helpful for storage pest management.

Abstract The value of fighting bulls (Lidia breed) is quantified based on their behavior in the bullring. Predicting this behavior is challenging because the heritability of behavior patterns is unknown and their interpretation subjective. An analysis was done of the possible relationship between bull behavior during pre-bullfight handling (unloading, first and second veterinary examinations) and during the bullfight. Behavioral parameter data was recorded for 200 adult bulls during pre-bullfight handling and the bullfight. Among the six genetic lines in the sample, the Santa Coloma and Albaserrada lines exhibited the highest values for mobility, aggressiveness, respiratory rate, and fight rate. Correlations were identified between some behaviors in pre-bullfight handling and others during the bullfight. Mobility during unloading and the first examination was positively correlated with Exit speed in the opening, Focus on banderillero (lancer on foot) in the second period of the bullfight and Determination in the third period. In contrast, aggressiveness during unloading was negatively correlated with mobility parameters during the second and third periods. No differences between animals were observed during the second examination, indicating that bulls quickly adapted to the corrals. The results suggest that some aspects of bull behavior prior to the bullfight can provide valuable information to bullfighters and breeders.

Resumen El valor productivo de cada toro de lidia se cuantifica en función de su comportamiento en la plaza, el cual es muy difícil de predecir, puesto que se desconoce la heredabilidad de cada tipo de comportamiento, y su interpretación suele ser subjetiva. En este trabajo, se analiza la posible relación de la actitud observada durante la estancia previa del toro en los corrales de la plaza, con el comportamiento desarrollado durante la lidia. Para ello, se han estudiado 200 toros adultos, registrando su comportamiento en los corrales y posteriormente durante la lidia. Se observan diferencias entre encastes en los patrones registrados previos a la lidia, siendo los encastes Santa Coloma y Albaserrada los que desarrollaron una mayor movilidad, agresividad, frecuencia respiratoria y tasa de peleas. Existen correlaciones significativas entre varias conductas recogidas durante el desembarque y los patrones etológicos registrados durante la lidia. La movilidad durante el desembarque y primer reconocimiento veterinario se correlaciona positivamente con la rapidez de salida, con la fijeza en banderillas y con la repetición de embestida en la muleta. De forma inversa la agresividad durante el desembarque, evidenciada en el mayor número de embestidas a los burladeros, se correlaciona negativamente con parámetros indicativos de movilidad durante las banderillas y muleta. Durante el segundo reconocimiento veterinario, no se observaron grandes diferencias de comportamiento entre animales, ya que el toro se aclimata rápidamente al nuevo entorno de los corrales. Los resultados obtenidos apuntan una relación entre la actitud del animal previa a la corrida, lo cual puede dar información valiosa a toreros y ganaderos.

The conceit that humans are exceptional and a species apart from nature continues to dominate traditional forms of curriculum in higher education. This article considers how an ethological curriculum might be used to disrupt current imaginaries informing prevailing higher education curricula practices in its rejection of a metaphysics of individualism that is foundational to traditional curriculum studies. An ethological curriculum thinks with more-than-human forms of life in relational ways to consider how we might work differently in higher education. The article offers four propositions as launching points, inflections or forces which can potentiate an ethological curriculum - cultivating attunement, attentiveness and noticing; becoming-with; rendering each other capable; and engaging response-ably.

ABSTRACT The aim of this study was to evaluate the behaviour and physiological response of Brahman cows grazing in silvopastoral arrangements with scattered trees. The study was conducted in Puerto Nare, Antioquia, Colombia. Two productive systems were typified: a system with relevant shade cover with discontinuous trees and shrubs and a central alley of trees (protocol A) and a control system with scarce tree cover (protocol B). Each system included 19 Brahman cows with calves at foot. Lower environmental temperature was recorded in the paddocks of protocol A (p=0.04) and a higher respiratory rate in cows of protocol B (p=0.0001). There were no differences in dry matter intake (p=0.40), but there was more time dedicated to night grazing by cows from Protocol B (p=0.0017). It is concluded that silvopastoral systems with an adequate offer of shade allow to reduce the ambient temperature by up to 2°C, promoting welfare and comfort to Bos indicus cattle reared in tropical conditions.

RESUMEN El objetivo del estudio fue evaluar el comportamiento y respuesta fisiológica en pastoreo de vacas Brahman en arreglos silvopastoriles con árboles dispersos. El estudio se realizó en Puerto Nare, Antioquia, Colombia. Se tipificaron dos sistemas productivos: un sistema con revestimiento pertinente de sombra con árboles y arbustos discontinuos y un callejón central de árboles (protocolo A) y un sistema control con escasa cubierta de árboles (protocolo B). Cada sistema incluyó a 19 vacas Brahman con sus crías. Se registró menor temperatura ambiental en los potreros del protocolo A (p=0.04) y una frecuencia respiratoria mayor en las vacas del protocolo B (p=0.0001). No hubo diferencias en la ingesta de materia seca (p=0.40), pero hubo mayor tiempo dedicado al pastoreo nocturno en las vacas del Protocolo B (p=0.0017). Se concluye que los sistemas silvopastoriles con adecuada oferta de sombra permiten reducir la temperatura ambiente hasta en 2° C, propiciando mayor bienestar y comodidad a bovinos Bos indicus alojados en condiciones de trópico.

Abstract The science of sensory ecology formally emerged in the book of Ali (1978), when behavioral ecology was gaining popularity. Until 2020, three main books were written on the subject, in 1992 (Dusenbery 1992), 2001 (Barth & Schmid 2001) and 2013 (Stevens 2013). The definitions of sensory ecology provided by Ali emphasize adaptation, optimality and fitness. These are main concepts of behavioral ecology but the last two are not necessarily fundamentals of sensory ecology. Here I looked at the evolution of the concept of sensory ecology and tried to understand whether there is evidence that the definitions given in 1978 had been influenced by behavioral ecology. I have counted the appearances of these three words (adapt*, optim* and fitness) in these books, divided by the number of words in each book, and compared the numbers to the definitions of sensory ecology given. Authors in Ali´s book often use adaptation but seldom deal with optimality or fitness. I suggest that the appearance of these keywords of behavioral ecology in the definitions of sensory ecology in Ali´s book was maybe a necessity to fit in the paradigms of that time. Sensory ecology was actually mechanistic in 1978 and 1992. Sensory ecology is now both mechanistic and evolutionary.

ABSTRACT Pair-formation, courtship, copulatory, and post-copulatory behaviors of Eidmanacris meridionalis Desutter-Grandcolas, 1995, were described under laboratory conditions and compared with congeneric species and other Phalangopsidae crickets whose mating behavior has been previously studied. Field observations for the species are also reported. Mating behaviors were observed in E. meridionalis couples: they first remained motionless, and then began walking through the arena screening the substrate. Mating behavior started with antennal contact, followed by males positioning themselves in front of females, that, when receptive, mounted on the males back and started feeding on metanotum secretions of the males. Copulation (female-above-male position) started with the engaging of copulatory structures and stopped with couple detachment. The end-to-end position was observed once, right after couple detachment. Males always remained with the spermatophore, which was eaten after removal or, alternatively, left in the substrate. The main differences in mating behavior of Eidmanacris species regard the mating position and the duration of the reproductive stages, suggesting that other reproductive repertoires can be observed in the genus since 27 species have not yet been studied in regards their reproductive behavior. We can also assume that the morphological, genetic, and chemical diversity found among the species of Phalangopsidae reflects in the behaviors of pair-formation, courtship, copulation, and post-copulation, leading to a diversity of copulation positions, duration of the stages, methods of attracting partners and parental investment. The description of Phalangopsidae mating patterns can provide important information for future evolutionary and phylogenetic studies, apart from useful for distinguishing cryptic species.

Abstract The objective of this study was to obtain data on the testicular biometry of the white-lipped peccary (Tayassu pecari) and to verify if there is a correlation between the individual’s biometric data with their dominance rank. Data were collected from 16 adult males, aged between two and seven years, who made up the same group. By the agonistic interactions analyses we calculated the linearity indexes (h') of the dominance hierarchy and dominance rank. At the end of the behavioral observations, males were captured to collect biometric data from the testis. White-lipped peccaries showed testicles located in a perineal position, inclined cranio-ventrally with oval shape, flattened laterally and with tenso-elastic consistency (2.54±0.07). There was variance in the means (± standard deviation) of testis length (5.88±1.05cm), width (4.24 ± 0.98cm), height (4.44±0.86cm), and total scrotal width (8.78±17.05). The linear dominance hierarchy described the social structure of the males of this group (h'>0.9), with probability of linearity in the hierarchy greater than chance (P = 0.02). There was a correlation between dominance rank with the body mass, length and volume of the testicles. As in general the dimensions of the testicles are directly correlated with sperm production and also testosterone, this characteristic favors the reproductive performance of dominant white-lips males. Therefore, the characteristics of testicular biometry of white-lips should be considered for the selection of individuals more likely to reproduce in captivity favoring the conservation of this vulnerable species.

Resumo O objetivo neste estudo foi obter dados sobre a biometria testicular do queixada (Tayassu pecari) e verificar se há correlação entre os dados biométricos do indivíduo com seu posto de dominância. Os dados foram coletados de 16 queixadas adultos, com idades entre dois e sete anos, que compunham o mesmo grupo. Por meio de análises das interações agonísticas foram calculados os índices de linearidade (h') da hierarquia de dominância e determinado o rank dos indivíduos. Ao final das observações comportamentais, os machos foram capturados para coleta de dados biométricos do testículo. Os queixadas apresentaram testículos localizados em posição perineal, inclinados cranioventralmente com formato oval, achatados láterolateralmente e com consistência tensoelástica (2,54±0,07). Houve variação nas médias (± desvio padrão) do comprimento testicular (5,88±1,05cm), largura (4,24±0,98cm), altura (4,44±0,86cm) e largura escrotal total (8,78±17,05). A hierarquia de dominância linear descreveu a estrutura social dos machos desse grupo (h'>0,9), com probabilidade de linearidade na hierarquia maior que o acaso (P = 0,02). Houve correlação entre a classificação de dominância com a massa corporal, comprimento e volume dos testículos. Como em geral as dimensões dos testículos estão diretamente correlacionadas com a produção de esperma e também de testosterona, essa característica favorece o desempenho reprodutivo de machos de queixadas brancos dominantes. Portanto, as características da biometria testicular de queixadas devem ser consideradas para a seleção de indivíduos com maior probabilidade de reprodução em cativeiro favorecendo a conservação desta espécie vulnerável.

Abstract Cerambycidae beetles limit production and establishment of forest and fruit trees. Oncideres cervina Thomson, 1868 (Coleoptera: Cerambycidae) is one of the most important species. The objective was to record O. cervina girdling branches of Persea americana Mill. (Lauraceae) for the first time, check the number of oviposition incisions (Noi) as a function of the diameter of branch sections, period of emergence, and describe the larval-pupal chamber. Individuals of O. cervina were observed, for the first time, in P. americana orchards in Santa Maria, Rio Grande do Sul, Brazil. The middle section of branches (40-60 cm interval) had higher number of incisions. Girdled branches with a diameter of 40-50 mm had higher number of them. Adults emerged from November through January. Larval-pupal boreholes had diameters between 9 and 11 mm, and average tunnel length was 28 mm, with a mean volume of consumed wood of 4.3 mL. This information is useful for establishing integrated pest management practices against O. cervina in P. americana since this crop has a high added value and can be significantly compromised by attack by Cerambycidae beetles.

Resumo Os besouros da família Cerambycidae limitam a produção e o estabelecimento de essências florestais e frutíferas. Oncideres cervina Thomson, 1868 (Coleoptera: Cerambycidae) é uma das espécies mais importantes. O objetivo foi registrar O. cervina danificando ramos de Persea americana Mill. (Lauraceae) pela primeira vez, verificar o número de incisões de postura em relação ao diâmetro das secções dos ramos, período de emergência e descrever a galeria larval-pupal. Indivíduos de O. cervina foram observados pela primeira vez em pomares de P. americana em Santa Maria, Rio Grande do Sul, Brasil. A secção média dos ramos (intervalo de 40-60 cm) apresentou maior número de incisões. Ramos danificados com diâmetro de 40-50 mm tiveram maior número delas. Adultos emergiram de novembro a janeiro. Os orifícios larvais-pupais tinham diâmetros entre 9 e 11 mm, e o comprimento médio da galeria era de 28 mm, com um volume médio de madeira consumida de 4,3 mL. Essas informações são úteis para estabelecer práticas integradas de manejo de pragas contra O. cervina em P. americana, já que essa cultura tem alto valor agregado e pode ser significativamente comprometida pelo ataque de besouros da família Cerambycidae.

Conclusiones: la gallineta azul presenta el mayor pico de actividad entre las 15:00 y 16:00 horas. Su patrón de coloración está dominado por dos tonos (gris y azul), en la localidad de investigación se le conoce como “gallineta azul”, diferente a lo descrito en Tinamus osgoodi “Tinamu negro”. Los huevos encontrados son totalmente diferentes en forma y color a los huevos de la raza nominal. Los hallazgos indican época reproductiva desde diciembre hasta mayo.

Abstract Goal: To evidence and infer about the pattern of daily activity, reproductive aspects, vocalizations and plumage coloration of the blue moorhen (Tinamus osgoodi hershkovitzi), in a population located in the Andean foothills of Colombia. Scope: To describe/contrast pattern of daily activity, plumage coloration, reproductive aspects and vocalization on what has been described for Tinamus osgoodi in other localities. Methodology: Ad libitum surveys were carried out and 17 camera traps were installed in La Cristalina Reserve, located in Serranía de los Churumbelos, municipality of Piamonte, Cauca, Colombia. Records were consolidated and classified into independent events that were analyzed through graphs. The information obtained was compared with existing literature of the species and related species. Main results: 10 biological samples of T. o. hershkovitzi were obtained, 9 of them were eggs and one individual adult female . Additionally, 17 vocalizations with three identified patterns were recorded. The camera trap captured 64 independent events, including a precopulation event. Conclusions: The blue moorhen presents the highest peak of activity between 3:00 p.m. and 4:00 p.m. Its color pattern is dominated by two tones (gray and blue). In the research location it is known as “blue hen”, different from what is described in Tinamus osgoodi “Black Tinamu”. The eggs found are totally different in shape and color from the eggs of the nominal breed. The findings indicate the reproductive season from December to May.

Resumen: El Pecarí labiado es gregario con manadas de hasta 300 individuos, habita bosques húmedos y xerofíticos. El pecarí de collar forma grupos de hasta 50 individuos y presenta una gran plasticidad ecológica, por la variedad de ambientes en el que vive. Ambas especies son depredadoras de semillas y presas naturales de carnívoros. Presentan amenazas como la pérdida y fragmentación de hábitats, y la cacería furtiva. Esta investigación tuvo como objetivos: (1) contribuir al conocimiento de la distribución y ocupación de sitios por T. pecari y P. tajacu en relación a características del paisaje, (2) describir los patrones de actividad diaria en paisajes ganaderos del Chaco Seco, paraguayo. Se establecieron 45 estaciones de muestreos en la Estancia Montania (Departamento de Boquerón, Paraguay). En cada sitio se colocó una cámara trampa, durante los años 2015 a 2017. Cada cámara fue ubicada en senderos de fauna, las fotografías obtenidas fueron clasificadas y analizadas con ayuda de los programas (DataOrganize y DataAnalyze). T. pecari registró mayor uso en sitios con mayor cobertura boscosa, esto se debería a la disponibilidad mayor de alimentos. P. tajacu, no mostró diferencias significativas en el uso de hábitat en función a la cobertura boscosa. Los patrones de actividad de ambas especies no muestran una segregación temporal.

Abstract: The white lipped peccary is gregarious with herds of up to 300 individuals and it lives in humid and xerophytic forests. The collared peccary forms groups of up to 50 individuals and shows great ecological plasticity due to the variety of environments it lives in. Both species are seed predators and natural prey for carnivores. They are faced by threats such as loss and fragmentation of habitat and poaching. This investigation’s objectives were: (1) to contribute to the knowledge on the distribution and occupation of T. pecari and P. tajacu in relation to landscape characteristics, (2) to describe activity patterns in productive landscapes in the Paragua- yan Dry Chaco. 45 sampling stations were established at Estancia Montania (Boquerón Department, Paraguay). A camera trap was placed at each station from 2015 to 2017. Each camera was placed on a wildlife trail. The photographs obtained were classified and analyzed using program (DataOrganize and DataAnalyze). T. pecari registered greater use in places with more forest coverage due to the higher availability of food. P. tajacu did not demonstrate significant differences in habitat use with respect to forest coverage. The behavioral patterns of the species do not show temporal segregation.

Resumen La estenosis aórtica es la valvulopatía más frecuente en los países desarrollados. La etiología degenerativa es la principal, esto está íntimamente relacionado con una tendencia exponencial en la longevidad de la población actual; por lo que sería correcto esperar un aumento en la casuística de esta patología. El reemplazo valvular aórtico, ya sea percutáneo o quirúrgico, es la estrategia casi única de manejo. Las guías de manejo de las distintas sociedades científicas, actualmente, norman la realización del reemplazo valvular como indicación principal en aquellos pacientes portadores de estenosis aórtica severa que, además, presenten síntomas o bien presenten datos de reducción en su fracción de eyección. Sin embargo, varios estudios han demostrado el beneficio de no retrasar la intervención de estos pacientes y por el contrario realizar la intervención valvular de forma temprana.

Abstract Aortic stenosis is currently the most common valve disease in developed countries. Degenerative ethology is the main one, this being intimately related to the exponential trend towards longevity in the current population. Aortic valve replacement, either percutaneous or open, is almost the only management strategy. The current management guidelines of the different scientific societies regulate the performance of valve replacement in patients with severe aortic stenosis who also present symptoms or data of reduced ejection fraction. However, several studies have shown the benefit of not delaying the management of these patients and, on the contrary, performing valve intervention early.

Resumen En 1874, Florentino Ameghino (1853-1911) recolectó un extraño loricárido en las aguas del Río Luján, fundando una nueva especie. Lo denomina Typupiscis Lujanensis, hace tomar cuatro fotografías y lo presenta el mismo año al director del Museo Público Germán Burmeister, quien desestima el hallazgo al clasificarlo, erróneamente, como Hypostomus plecostomus. El análisis de tres de estas albúminas, junto a los testimonios sobre la morfología y etología de un ejemplar en cautiverio, permite determinar que los especímenes extraídos del Río Luján en 1874 y en 1884, pertenecen a Ancistrus cirrhosus, especie que ya había sido recolectada en el Plata por d’Orbigny en 1827 y descripta por Valenciennes en 1847. Las albúminas de Ancistrus por Annaratone, junto a las de restos de Panochtus encargadas por Burmeister hacia 1874 colocan a ambos entre los pioneros de la utilización de la fotografía en objetos de historia natural en Argentina.

Abstract In 1874, Florentino Ameghino (1853-1911) collected a strange catfish in the Luján river, founding a new species. He named it Typupiscis Lujanensis, took four photographs and presented it to the director of the Public Museum, Germán Burmeister, who dismisses the finding by erroneously classifying it as Hypostomus plecostomus. The analysis of three of these albumen photographs, together with penecontemporaneous testimonies on the morphology and the ethology of a specimen in captivity, allow to determine that the specimens fished in the Luján river in 1874 and in 1884, belong to Ancistrus cirrhosus, a species that was already collected in the Río de la Plata by d’Orbigny in 1827 and described by Valenciennes in 1847. The Annaratone’s albumen of Ancistrus, together with those of Panochtus commissioned by Burmeister in 1874 place them among the pioneers of the use of photography in natural sciences in Argentina.

RESUMO: Objetivou-se avaliar o grau de ativação e relaxamento muscular de equinos de patrulhamento submetidos à exercícios de mobilização dinâmica associados ou não à acupuntura. Doze cavalos castrados, sem raça definida, com idade de 10 ± 2,0 anos, foram distribuídos em três tratamentos: tratamento com uma sessão única de exercícios de mobilização dinâmica (flexão cervical longitudinal da cabeça entre os cascos, entre os carpos e até o peito); tratamento com sessão única de acupuntura (20 minutos); e tratamento com sessão única composta por exercícios de mobilização dinâmica associados a acupuntura. Foram analisadas imagens termográficas antes e após a aplicação dos tratamentos das regiões cervical, torácica, dorsal, abdominal e pélvica. A avaliação comportamental foi obtida por meio de filmagens 5 minutos antes e 10 minutos após o término da aplicação dos tratamentos, de maneira ininterrupta. Houve aumento (P < 0,0001) na temperatura corporal dos animais ao final da sessão única de exercícios funcionais para todas as regiões estudadas, sendo a cervical e torácica aquelas com maior valor de temperatura final. Não houve variação da temperatura nos demais tratamentos (P > 0,05). Todos os tratamentos geraram maior frequência (P < 0,05) na expressão de comportamentos relacionados ao relaxamento. A realização de uma sessão única de exercícios de mobilização dinâmica é suficiente para promover uma intensa resposta muscular em todo o corpo do equino, e tanto os exercícios funcionais quanto a acupuntura, de maneira individual ou associada, foram capazes de promover relaxamento muscular e mental, interferindo de maneira positiva no bem-estar dos animais.

ABSTRACT: The present research evaluated muscle activation degrees and relaxation of patrolling horses submitted to dynamic mobilization exercises, associated or not with acupuncture. Twelve mixed breed gelding, aged 10 ± 2.0 years, were distributed in three treatments. Treatment with a single session of dynamic mobilization exercises (longitudinal cervical flexion of head between hooves, between carpus and to up to chest); treatment with a single acupuncture session during 20 minutes, and treatment with a single session of dynamic mobilization exercises with acupuncture. Thermographic images were analyzed before and after applying treatments to the cervical, thoracic, dorsal, abdominal and pelvic regions. Animal behavior was assessed through five minutes filming, before and ten minutes after the end of each treatment application, in an uninterrupted way. Increase in animals body temperature at the end of the single session of functional exercises (P < 0.0001) at all animal regions were reported, being cervical and thoracic areas with highest final temperature values. There was no temperature variation for other treatments (P > 0.05). All treatments stimulated higher expression frequency (P < 0.05) of relaxation behaviors. A single dynamic mobilization exercises session is enough to promote intense muscular response in entire horse body; and with acupuncture, individually or associated, promoted muscle and mental relaxation, interfering positively in animal welfare.

Abstract Although communication capabilities are displayed by many vertebrate groups, some repertoires are poorly known, such as the case of xenarthrans, particularly armadillos, for which vocalization as a source of communicating to others remains poorly understood and relies on punctual reports of sounds. Here we provide the first description of a behavioral response associated with sound emission of two subjects of Dasypus novemcinctus. Both audio and visual registration was performed to subsequent analyses of expressed behaviors and emitted calls, which accounted for 76 vocalizations from a total of eight video recordings randomly collected from 2017 to 2019. Sound is acoustically characterized by both inhale and exhale phases composed of two vocal units, and no harmonic structure was observed. Once the subjects have always produced these vocalizations while cornered and exhibiting defensive behavior against another subject/human disturbance, these vocalizations were termed as distress. Subjects produced a hiss-purr-like sound while trying to avoid contact with another by bowing or lowering their bodies, humping, or even moving elsewhere when sound production ceased. This shows that the sound repertoire of armadillos is still to be unveiled and seems to be much more complex than previously thought.
