Estudo comportamental de Besourão-de-rabo-branco Phaethornis superciliosus (Aves, Trochilidae) no Parque Ecológico de Gunma

A comunicação acústica em beija-flores durante muito tempo foi negligenciada em função da coloração conspícua que representa uma sofisticada comunicação visual da maioria dos representantes deste grupo. Entretanto, estudos recentes constataram que há indícios de aprendizagem vocal em algumas espécies de Trochilidae. O presente estudo aborda o comportamento vocal do beija-flor Phaethornis superciliosus, espécie abundante na região amazônica. Esta espécie apresenta como sistema de acasalamento a formação em arena, que consiste na agregação de machos em um pequeno território, onde se exibem para outros machos e fêmeas, com o intuito de atrair estas últimas para acasalar. O objetivo geral deste trabalho foi analisar o comportamento vocal de P. superciliosus dispostos em seis arenas no Parque Ecológico de Gunma, Santa Bárbara do Pará, 50 km ao norte de Belém, considerando a emissão e estrutura física do canto, seu repertório, a frequência de emissão ao longo do dia e do ano e a dinâmica das arenas. Verificamos que a população estudada apresenta um repertório vocal composto de duas notas que são emitidas de maneira alternada. Os cantos dos indivíduos analisados apresentaram diferenças significativas entre si considerando os parâmetros físicos do som (frequências máxima e mínima, duração e intervalo entre as notas e o ritmo de emissão das notas). Esta diferenciação inter-individual pode estar relacionada à seleção sexual, na qual o canto pode permitir o reconhecimento individual, sua posição social e seu desempenho para a atração das fêmeas. Constatamos que a atividade vocal é mais intensa no segundo semestre, entre junho e novembro, período que provavelmente corresponde à estação reprodutiva. Realizamos testes de playback, que consistem em reproduzir um som previamente gravado e registrar a resposta provocada em uma das arenas em dois pontos distintos, simulando a entrada de outro indivíduo. Constatamos que o som emitido em resposta ao teste diferiu significativamente do canto espontâneo em todos os parâmetros físicos analisados. A resposta ao playback mostra que houve uma redução na faixa de frequência com que o canto foi emitido e o ritmo de emissão de notas mais rápido. Tais características do canto podem estarrelacionadas a um comportamento mais agressivo. As arenas são formadas emáreas de borda e sempre próximas a igarapés, com o tamanho da área variando entre 86m² e 14m², compostas de dois a quatro indivíduos distantes de 7m a 72m entre si. Nossos resultados mostraram que a organização social da arena deve ser melhor compreendida através de estudos mais detalhados sobre o possível significado que as diferenças individuais no canto podem representar para o estabelecimento da posição hierárquica dos indivíduos nas arenas.

História natural de Hypsiboas albopunctatus (Anura: Hylidae) na região de Rio Claro, estado de São Paulo

Natural history studies aim to know where the organisms live, what they do, and their relationships within the environment, including the other organisms. The anurans, among other vertebrates, exhibits the greatest variety of reproductive modes as well as a high complexity of social organization, that may enable a lot of naturalist studies. Anurans modes of organization are direct related to parental care, vocalization of chorus organization, and with males territoriality. In general, the social organization is influenced by species reproductive pattern. This study aim to get information about the natural history of Hypsiboas albopunctatus (perereca-cabrinha) a species of the family Hylidae, on the region of Rio Claro Municipality, São Paulo State, Brazil. The major aspects discussed were: seasonality, spatial distribution, acoustic and visual communication, reproductive mode, reproductive site, abiotic factors influences, territoriality, courtship behaviour, satellite male behavior, embrace and defensive behavior. To obtain this data, nocturnal field excursions were realized monthly. Two sites of Rio Claro county where chosen as studies sites, the sítio Cantaclaro (22o19’36’’S; 47o42’57’’O), on the District of Itapé and Floresta Estadual Edmundo Navarro de Andrade (FEENA) (22o24’58’’S; 47o31’26’’O).

Plano de responsabilidade social empresarial para a Raízen: projeto 4 patas

The process of globalization resulted in a variety of new products emerging. Companies were obliged to find new ways of maintaining the attractiveness for their products to sustain their brands in the economic field. So in this scenario social accountability became an important subject for companies that want to achieve a positive image among consumers. This paper aims to explain how organizational communication is essential to create and manage social accountability in a company. Aiming to explain the relation between organizational communication and social accountability, this final project had three main purposes: establish the connection between organizational communication and social accountability, point out and discuss the main strategies in this communication field, and then propose an action plan for Raízen to solve an established problem in one of its factories

Papel especial nas artes visuais

The air part of the cassava plant is considered an agronomical residue due to the great volume produced in Brazil, the second biggest world producer of this plant. It is a residue which presents possibilities of being used as a non-wooden raw material in the production of pulp due to the fact that its stem and presenting a high concentration of fibers, which accounts for 30,18% in try weight. Under such considerations, this paper dealt with the aspects of the pulp obtaining process of this cassava agronomical residue for the production of special papers, with further assessment of its use in the visual communication.

Procedimentos metodológicos em design gráfico voltados a jornais diários impressos: estudos e relatos de experiência

This paper summarizes a research that has been developed from the concern about a company’s strategic planning, once regarding the product development process and its methodological guidelines. Our goal was to check if there is an ideal methodology, peculiar to the graphic design, which could be applied to a printed newspaper condition. And then, we could deduce, according to the design practices in newspapers, its relevance. We did not intend to create a specific graphic design methodology for daily newspapers, nor the analysis of methods, but we wanted to emphasize that the familiarization with acknowledged methods in the field of visual communication, during the process of professional formation, might ease good choices in the work practice on design. The understanding of the gradual introduction of graphic design on printed daily newspapers brings about, thus, not only their visual improvement, but also allows that this kind of journalism (which depends on a graphic interface in order to make their product come true) reconsider the newspaper as a whole.

Cinquenta anos do Mini Cooper: uma viagem pelo tempo por meio da Ilustração

The use of images as a mean of human knowledge transmission dates from the earliest records of visual communication with the cave paintings. Throughout history, the communicating function remained and was extended for a variety of approaches, including illustration, which plays an important role by transmitting a content to be communicated on a creative and unique way. The advertising area relies largely on the communicative power of illustration, using it as a visual aid on different ways and medias. The advertising pieces aimed at the automotive sector – especially those developed by BMW for the Mini Cooper model – broadly employs illustrations to spread the word about the product and its attributes, seeking to communicate it using an original way. With a qualitative approach to the case study, this article analyzes the illustrations produced by the South African design studio Am I Collective as part of a video prepared by South African advertising agency Blackriver FC as a celebration campaign for the fifty years of vehicle Mini Cooper, celebrated on 2009, and it aims to identify the illustrations visuals and compositions used in the construction of the covered temporal panorama.

The Underwater Photic Environment of Cape Maclear, Lake Malawi: Comparison Between Rock- and Sand-Bottom Habitats and Implications for Cichlid Fish Vision

Lake Malawi boasts the highest diversity of freshwater fishes in the world. Nearshore sites are categorized according to their bottom substrate, rock or sand, and these habitats host divergent assemblages of cichlid fishes. Sexual selection driven by mate choice in cichlids led to spectacular diversification in male nuptial coloration. This suggests that the spectral radiance contrast of fish, the main determinant of visibility under water, plays a crucial role in cichlid visual communication. This study provides the first detailed description of underwater irradiance, radiance and beam attenuation at selected sites representing two major habitats in Lake Malawi. These quantities are essential for estimating radiance contrast and, thus, the constraints imposed on fish body coloration. Irradiance spectra in the sand habitat were shifted to longer wavelengths compared with those in the rock habitat. Beam attenuation in the sand habitat was higher than in the rock habitat. The effects of water depth, bottom depth and proximity to the lake bottom on radiometric quantities are discussed. The radiance contrast of targets exhibiting diffused and spectrally uniform reflectance depended on habitat type in deep water but not in shallow water. In deep water, radiance contrast of such targets was maximal at long wavelengths in the sand habitat and at short wavelengths in the rock habitat. Thus, to achieve conspicuousness, color patterns of rock-and sand-dwelling cichlids would be restricted to short and long wavelengths, respectively. This study provides a useful platform for the examination of cichlid visual communication.

Subjective Evaluation of Transmission Errors in IPTV and 3DTV

The increase of multimedia services delivered over packet-based networks has entailed greater quality expectations of the end-users. This has led to an intensive research on techniques for evaluating the quality of experience perceived by the viewers of audiovisual content, considering the different degradations that it could suffer along the broadcasting system. In this paper, a comprehensive study of the impact of transmission errors affecting video and audio in IPTV is presented. With this aim, subjective assessment tests were carried out proposing a novel methodology trying to keep as close as possible home environment viewing conditions. Also 3DTV content in side-by-side format has been used in the experiments to compare the impact of the degradations. The results provide a better understanding of the effects of transmission errors, and show that the QoE related to the first approach of 3DTV is acceptable, but the visual discomfort that it causes should be reduced.

Temporal task allocation in periodic environments. An approach based on synchronization

In this paper, we study a robot swarm that has to perform task allocation in an environment that features periodic properties. In this environment, tasks appear in different areas following periodic temporal patterns. The swarm has to reallocate its workforce periodically, performing a temporal task allocation that must be synchronized with the environment to be effective. We tackle temporal task allocation using methods and concepts that we borrow from the signal processing literature. In particular, we propose a distributed temporal task allocation algorithm that synchronizes robots of the swarm with the environment and with each other. In this algorithm, robots use only local information and a simple visual communication protocol based on light blinking. Our results show that a robot swarm that uses the proposed temporal task allocation algorithm performs considerably more tasks than a swarm that uses a greedy algorithm.
