1. Unusual effect of chemical communication on social aggression in juvenile cichlid fish Cichlasoma paranaense (Cichliformes: Cichlidae)
RESUMO Algumas espécies de peixes são organizadas socialmente e apresentam uma ordem de rank social que é alcançada por meio de interações agressivas. Após o estabelecimento da hierarquia, essas espécies comunicam seu rank por diversas pistas sensoriais, essa comunicação é adaptativa, pois reduz os efeitos prejudiciais das lutas físicas. Peixes c

2. Vocal assessment of addicts on methadone therapy via the RBH scale and objective acoustic parameters
Resumo Introdução: Um grande número de pessoas em todo o mundo luta diariamente para livrar-se de seu vício em substâncias psicoativas ilegais. Com o objetivo de criar uma atmosfera de supervisão melhorada, comunicação estabelecida e melhora da qualidade de vida para drogaditos, foram criados centros que fornecem a substância substitutiva metadona.

3. Acoustic communication in two species of the Hypsiboas albopunctatus group (Anura: Hylidae) in sympatry and allopatry
ABSTRACT Tropical anuran communities are very diverse. Nevertheless, much of their ecological and historical processes remain unknown. Bioacoustical studies are important to help to solve these puzzles. In the present study we examined the effect of environmental (air temperature and humidity) and morphological (body size) attributes on the acoustic paramete

4. How do males of Hypsiboas goianus (Hylidae: Anura) respond to conspecific acoustic stimuli?
ABSTRACT Acoustic communication plays an important role in the social behavior of anurans. Acoustic signals, which can be used in different contexts such as mate attraction and territory defense, may mediate social interactions among individuals. Herein, we used playback experiments to test whether males of Hypsiboas goianus (Lutz, 1968) change their vocal b

5. Advertisement call of Dendropsophus microps (Anura: Hylidae) from two populations from southeastern Brazil
In anurans, acoustic communication is a major mechanism of pre-zygotic isolation, since it carries information about species recognition. Detailed descriptions of the acoustic properties of anuran advertisement calls provide important data to taxonomist and to the understanding of the evolution of the group. Herein we re-describe the advertisement call of th

6. Acoustic communication in insect disease vectors
Acoustic signalling has been extensively studied in insect species, which has led to a better understanding of sexual communication, sexual selection and modes of speciation. The significance of acoustic signals for a blood-sucking insect was first reported in the XIX century by Christopher Johnston, studying the hearing organs of mosquitoes, but has receive

7. Advertisement call propagation and species recognition in anurans: in time and space / Propagação e reconhecimento específico do canto de anúncio de anuros: no tempo e no espaço
This study evaluates the influence of the vegetation structure on the advertisement call propagation and the evolution of acoustic communication in anurans. The first chapter reviews the literature on the effects of vegetation in the advertisement-call transmission, addressing directly or not, the Acoustic Adaptation Hypothesis. The studies found were analyz

8. Ontogenia do Padrão Vocal Individual do Peixe-Boi da Amazônia Trichechus inunguis (Sirenia, Trichechidae)
There are evidences that Amazonian manatee convey identity information, to its conspecifics, using sounds. Evidences about the presence of vocal signature and individual recognition have been documented in the specie. However, there is little information about the vocal behavior and the development of the individual vocal pattern for this species. The vocali

9. The use of Herpsilochmus longirostris Pelzeln, 1868 (Passeriformes; Thamnophilidae) as adaptation model acoustics / A utilização de Herpsilochmus longirostris Pelzeln, 1868 (Passeriformes; Thamnophilidae) como modelo de adaptação acústica
The acoustics communication is well developed in birds. According to Acoustics Adaptation Hypothesis the birds tend to maximize the transmission of the acoustic signals in accordance with the environment where they are adapted. This work had as objective to describe the vocalizations of Herpsilochmus longirostris, Pelzeln, 1868 (Passeriformes: Tamnophilidae)

10. Audição e Voz: a interface no envelhecimento. / Hearing and voice: its interface in ageing
Introduction: According to data from the Brazilian Institute of Geography and Statistics, the life expectancy estimated at birth in Brazil, for both sex, increased to 71,3 years. The life expectancy increase reflects in special attention necessities to the elderly population, and it falls to the Speech-Language and Hearing Science the parcel that concerns to

11. Experiences of parents of deaf children face the possibility of their children to submit to the cochlear implant / Vivencias de pais de crianças surdas frente a possibilidade de seus filhos se submeterem ao implante coclear
Cochlear implants are currently used in adults and children with acquired or congenital deep and bilateral neurosensory hearing loss, whose hearing was not improved by prosthesis. This is a resource that aims to create an ?electrical field? inside the cochlea in order to stimulate the acoustic fibers by sonorous impulses transformed into electrical signs, pr

12. Processamento auditivo (central): o discurso de um grupo de fonoaudiólogos / (Central) auditory processing: the speech of a group of speech-language pathologist/audilogist
The (central) auditory processing is the efficiency and effectiveness with which the central auditory nervous system processes the sounds, from its reception to its interpretation. Perceptual, cognitive and linguistic mechanisms have an influence on recognizing, decoding and interpreting the information heard. Because it consists of a cerebral activity, it i
