1. USING SOUNDS PRODUCED BY PIGS TO IDENTIFY THERMONEUTRALITY ZONES FOR THERMAL ENVIRONMENT ASSESSMENT RATIOS
ABSTRACT Although dry bulb temperature (T) is the environmental variable most commonly used to classify thermal comfort in pigs, environmental assessment ratios provide more accurate information. The objective of this study was to correlate the sound pressure levels (SPL) produced by piglet vocalization with the thermal environment observed during the nurser

2. Influence of social stress on value of minimal anesthetic concentration of isuflurano in guan (Penelope obscura) captured in wildlife
RESUMO: Este estudo teve como objetivo determinar e avaliar se há diferença nos valores de CAM em jacus (Penelope obscura) capturados em vida livre e submetidos a diferentes condições de estresse social. Foram utilizadas 27 aves da espécie jacu (P. obscura) de vida livre, que depois de capturados foram alocados em dois grupos: 10 animais que permanecera

3. EXPRESSÕES NEGATIVAS NA FALA DE UMA CRIANÇA BRASILEIRA E UMA CRIANÇA FRANCESA: ESTUDO DE CASOS
RESUMO: O trabalho é um estudo longitudinal de duas crianças, uma brasileira e uma francesa, e focaliza o desenvolvimento das expressões de negação na fala das duas. Objetiva mostrar que, no início, nas instâncias a que chamamos de “protonegações”, marcadas por gesto e vocalização, são indissociáveis e assumem sentido na interpretação do o

4. Comportamento territorial, vocalização e biologia reprodutiva de Allobates olfersioides (Anura: Aromobatidae)
RESUMO Em anfíbios a territorialidade, o cortejo elaborado e outras formas de comportamento, parecem estar mais associados a espécies que exibem o padrão de reprodução prolongado. A vocalização é um importante aspecto biológico relacionado à reprodução e ao comportamento social dos anuros. Este é o primeiro estudo com comportamento e vocalizaç�

5. Behavior affected by routine oxytocin injection in crossbred cows in the tropics
ABSTRACT The objective of the study was to determine the effect of routine intramuscular injection of oxytocin to induce milk ejection on behavior assessed in terms of stress and rectal temperature in crossbred cows (Bos indicus × Bos taurus) in the tropics of Veracruz, México. Immediately after calving, cows were milked twice a day (n = 210) and randomly

6. An Intelligent Procedure for the Detection and Classification of Chickens Infected by Clostridium Perfringens Based on their Vocalization
ABSTRACT In this study, an intelligent method was implemented for the detection and classification of chickens by infected Clostridium perfringens type A based on their vocalization. To this aim, the birds were first divided into two groups that were placed in separate cages with 15 chickens each. Chickens were inoculated with Clostridium perfringens type A

7. Aspectos reproductivos de Dendropsophus sanborni (Anura, Hylidae) en el nordeste de la Argentina
Reproductive aspects of Dendropsophus sanborni (Anura, Hylidae) in northeastern Argentina. The aim of this investigation was to characterize reproductive aspects of Dendropsophus sanborni (Schmidt, 1944) (Anura, Hylidae) in the northwest of Corrientes province, in northeastern Argentina. The reproductive cycles of males and females, the existence of sexual d

8. Effect of singing training on total laryngectomees wearing a tracheoesophageal voice prosthesis
PURPOSE: To assess the effect of a program of singing training on the voice of total laryngectomees wearing tracheoesophageal voice prosthesis, considering the quality of alaryngeal phonation, vocal extension and the musical elements of tunning and legato. METHODS: Five laryngectomees wearing tracheoesophageal voice prosthesis completed the singing training

9. Involvement of NK-1 receptors of the basolateral and central nuclei of the amygdala in the defensive behavior of rats / Participação dos receptores NK-1 dos núcleos basolateral e central da amígdala no comportamento defensivo de ratos
A substantial body of evidence obtained in the last decade demonstrated that the Substance P (SP) is an important mediator of the affective and emotional behaviors. SP is a pro-aversive compound when microinjected within the dorsal periaqueductal gray (dPAG). These effects are mediated by the type 1 neurokininergic receptors (NK-1), since the defensive behav

10. On the relationships between ultrasonic calling and anxiety-related behavior in rats
In the present review, the phenomenon of ultrasonic vocalization in rats will be outlined, including the three classes of vocalizations, namely 40-kHz calls of pups, and 22- and 50-kHz calls of juvenile and adult rats, their general relevance to behavioral neuroscience, and their special relevance to research on anxiety, fear, and defense mechanisms. Here, t

11. Behavioral evidence for cone-based ultraviolet vision in divergent bat species and implications for its evolution
We investigated the reactions of four bat species from four different lineages to UV light: Hipposideros armiger (Hodgson, 1835) and Scotophilus kuhlii Leach, 1821, which use constant frequency (CF) or frequency modulation (FM) echolocation, respectively; and Rousettus leschenaultii (Desmarest, 1820) and Cynopterus sphinx (Vahl, 1797), cave and tree-roosting

12. Distribution, vocalization and taxonomic status of hypsiboas roraima and h. angelicus (Amphibia: Anura: Hylidae)
The distribution of the poorly known hylid frog Hypsiboas roraima Duellman & Hoogmoed, on the Guiana Shield is redefined, including new records from Venezuela. The advertisement call of this species is analyzed and Hypsiboas angelicus Myers & Donnelly is associated as a junior synonym of H. roraima.
