1. 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�

2. Arranjos de música regional do sertão caipira e sua inserção no repertório de coros amadores / Choral arrangement, choral singing, amateur choir, Brazilian regional music, "sertão caipira".
This article proposes a reflection about the repertoire sung by amateur choirs, focusing on the process of elaboration of vocal arrangements based upon Brazilian regional music, especially country-hick songs (música caipira). The songs discussed here and their arrangements unfold a very particular thematic world, that of the music from one of Brazils variou

3. VocalizaÃÃo do sagui comum: influÃncias sociais e ontogÃnicas em ambiente natural
Os sagÃis comuns, Callithrix jacchus (Callithrichidae, Primates), vivem em grupos de trÃs a quinze indivÃduos, havendo um sistema de dominÃncia e a possibilidade de viver em monogamia, poliginia, poliandria ou poliginandria. Eles sÃo primatas neotropicais arbÃreos, endÃmicos da regiÃo Nordeste do Brasil, mas que nos Ãltimos anos foram amplamente int

4. A avaliação da perfomance no canto lírico : uma análise de conteúdo
In the musical field, issues of assessment and evaluation have been the subject of great discussion. There seems to be relatively little research on matters relating to the performance of classical singing in spite of the great diversity of material such as learning and course outcomes, content standards, curriculum standards, program handbooks, syllabus boo

5. Classificação semi-automatica do repertorio vocal do Sabia-laranjeira Turdus rufiventris
Based on studies of vocal repertoire of the Rufous-bellied Thrush Turdus rufiveniris (Aves, Passerifonnes, Turdinae), the objective in this research is to elaborate a method for semi-automatic c1assification of the songs notes (continuous units of sound). This research is based on calculations of correlation applied to images; through the technique know as T

6. Comportamento reprodutivo e comunicação sonora e hyla minuta Peters, 1872 : amphibia, anura, hylidae
The present work was carried out with the central purpose of studying the reproductive behavior of Hyla minuta in the municipality of Campinas, state of São Paulo, Brazil (22º48 S, 47º05 W, 650-700 m alt.). The influence of some abiotic factors (temperature, wind, thunder, moon luminosity, sunset, rain and fire) affecting the reproductive activity of H. m

7. Analise da comunicação sonora no anu-branco guira quira (aves: cuculidae), avaliações eco-etologicas e evolutivas
The vocal repertoire of the Guira Cuckoo Guira guira is described together with its behavioral contexts. The natural groups of Guiras that live at the Campus of the Universidade Estadual de Londrina in Paraná, Brazil, were studied. Important observations and recordings were also obtained from birds raised in captivity in the middle of the town and in the su

8. Effects of Continuous Noise on Avian Hearing and Vocal Development
Continuous loud noice was used to mask auditory feedback from vocal behavior of male canaries. Single unit techniques demonstrate partial deafness after noise exposure. Longer exposure caused greater deficits, with losses of high-frequency sensitivity. Males raised in noise to 40 days of age, then deafened surgically, thus totally deprived of auditory feedba

9. Auditory representation of the vocal repertoire in a songbird with multiple song types
Neural mechanisms for representing complex communication sounds must solve the problem of encoding multiple and potentially overlapping signals. Birdsong provides an excellent model for such processing, in that many songbird species produce multiple song types. Although auditory song representations in single song type species have been studied, how song is

10. Selection-based learning in bird song development.
Bird song is a model system for study of the neurobiology, development, and functions of learned vocal communication signals. Research on avian song learning has been dominated by an instructive model of learning--the sensorimotor model. Developmental plasticity is assumed to be based on the incorporation of novel material into the song repertoire. Experimen

11. Left hemisphere dominance for processing vocalizations in adult, but not infant, rhesus monkeys: field experiments.
In humans, the left hemisphere of the brain is dominant for processing language. To assess the evolutionary origins of this neuropsychological mechanism, playback experiments were conducted on a large population of free-ranging rhesus monkeys (Macaca mulatta). Playbacks provided an equal opportunity to orient the right or left ear toward the speaker. Results

12. Individual variation in neuron number predicts differences in the propensity for avian vocal imitation
Avian song learning involves memorizing and reproducing song material produced by conspecifics. In several species song repertoire size correlates with the overall volume of two song-related brain regions, the HVc (acronym used as the proper name) and the robust nucleus of the archistriatum (RA). We raised male zebra finches with two adult tutors and found t
