Resumo: | The aerial activities, leaps and slaps with parts of the body in the surface of water, are part of the behavioral repertoire of several species of cetaceans. Among them, the spinner dolphin, Stenella longirostris, shows greater diversity in such behavior. For the spinner dolphins of Fernando de Noronha, the aerial activities are classified as vertical and horizontal, with eight patterns to be noted (tail slap, head slap, motor boating, partial leap, leap, spin, tail over head and tail over head with spin) discriminated between these categories. Such behaviors can be used as a parameter to identify behavioral changes, as well as patterns of daily and seasonal activity. In this manner, this study aimed to characterize the frequency in performance of such activity while the dolphins were within the Dolphin Bay of Fernando de Noronha, and verify possible daily and seasonal hourly fluctuations on such behaviors. The data analyzed in this study was acquired during the period of January 2006 through December 2010, totaling 1431 days of observation from land set point, with 113027 aerial activities registered, daily average of 72,27 (SD=96,10). During 5478h and 54 min of observation the horizontal aerial activity was the most observed and rotation was the most executed pattern. Greater frequency of execution of aerial activity was observed in adults, but for both adults and calves, was observed a predominance of horizontal activities, with spin being the pattern most executed. Positive correlation was observed between the amount of aerial activity performed and the number of animals inside the Bay. Hourly daily fluctuation was observed in the expression of aerial activities by spinner dolphins, and was observed a peak of activity between 8h and 8h59min for the overall frequency relative of aerial activities, as well as for the categories and patterns. Seasonal differences were observed between the rainy and dry season with the greater amount of activity being observed during the rainy season. Nevertheless, the same profile of frequency relative of aerial activity was observed in both seasons with the peak amount being during the same period. When discriminated the aerial activities in categories and patterns, for both seasons, there was a similar pattern of hourly fluctuation; for most of parameters, higher frequency relative of execution of aerial activity remain between 8h and 8h59min |

Dentre elas, acredita-se que o golfinho-rotador, Stenella longirostris, seja a espécie que apresenta maior agilidade em tais comportamentos. Para os golfinhos-rotadores de Fernando de Noronha, as atividades aéreas são categorizadas em atividades aéreas verticais e horizontais, sendo oito (batida de cauda, batida de cabeça, motor de popa, caída, salto, rotação, inversão e pirueta) os padrões discriminados entre essas classes. Tais comportamentos podem ser usados como parâmetros para identificar alterações comportamentais, bem como os padrões de atividade diária e sazonais. Desta forma, o presente estudo teve por objetivo caracterizar a frequência de execução de atividades aéreas no decorrer do período em que os golfinhos-rotadores permanecem dentro da Baía dos Golfinhos de Fernando de Noronha, bem como verificar a existência de possíveis flutuações horárias diárias e sazonais na exibição de tais comportamentos. Para isso, foram analisados dados que compreendem o período entre janeiro de 2006 a dezembro de 2010, totalizando 1.431 dias de observação em ponto fixo, sendo registradas 113.027 atividades aéreas, média diária de 72,27 (DP=96,10). Nas 5.478 horas e 54 minutos de observação, as atividades aéreas horizontais foram observadas em maior frequência, sendo a rotação o padrão mais executado. Maior frequência de execução das atividades aéreas foi observada em indivíduos adultos, mas tanto para adultos quanto para filhotes, observou-se predomínio das atividades horizontais, com a rotação sendo o padrão mais executado. Correlação positiva foi observada entre a quantidade de atividades aéreas executadas e o número de animais dentro da Baía. Flutuação horária diária foi observada na expressão das atividades aéreas pelos golfinhos-rotadores, sendo observado maior pico de atividade no horário entre 8h e 8h59min, tanto para a frequência relativa total de atividades aéreas, quanto para as classes e os padrões. Diferenças entre as estações climáticas seca e chuvosa foram observadas, com maior registro de atividade aérea durante o período de chuvas. Entretanto, o perfil de distribuição da frequência relativa de atividades aéreas se assemelha para ambas as estações, mantendo o horário de maior pico de atividade. Quando discriminadas as atividades aéreas nas classes e nos padrões considerados, para ambas as estações observaram-se padrão de flutuação horária semelhante; para a maioria dos parâmetros analisados, maior frequência relativa de execução das atividades aéreas se mantém entre 8h e 8h59minConselho Nacional de Desenvolvimento Científico e Tecnológicoapplication/pdfporUniversidade Federal do Rio Grande do NortePrograma de Pós-Graduação em PsicobiologiaUFRNBREstudos de Comportamento; Psicologia FisiológicaStenella longirostrisgolfinho-rotadoratividades aéreasFernando de NoronhaSpinner dolphinsaerial activitiesCNPQ::CIENCIAS BIOLOGICASCaracterização da frequência de atividades aéreas do golfinho-rotador, Stenella longirostris (Gray, 1828), na Baía dos Golfinhos do Parque Nacional Marinho de Fernando de Noronhainfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFRNinstname:Universidade Federal do Rio Grande do Norte (UFRN)instacron:UFRNORIGINALRitaCC_DISSERT.pdfapplication/pdf2507687https://repositorio.ufrn.br/bitstream/123456789/17328/1/RitaCC_DISSERT.pdf4eeca6582506786804976f0255257b80MD51TEXTRitaCC_DISSERT.pdf.txtRitaCC_DISSERT.pdf.txtExtracted texttext/plain173732https://repositorio.ufrn.br/bitstream/123456789/17328/6/RitaCC_DISSERT.pdf.txtd25a16575cf83fa5a3804a4313c514d7MD56THUMBNAILRitaCC_DISSERT.pdf.jpgRitaCC_DISSERT.pdf.jpgIM Thumbnailimage/jpeg3114https://repositorio.ufrn.br/bitstream/123456789/17328/7/RitaCC_DISSERT.pdf.jpg52f497c49c7568c602d4e4a79c63477bMD57123456789/173282017-11-04 18:17:54.781oai:https://repositorio.ufrn.br:123456789/17328Repositório de PublicaçõesPUBhttp://repositorio.ufrn.br/oai/opendoar:2017-11-04T21:17:54Repositório Institucional da UFRN - Universidade Federal do Rio Grande do Norte (UFRN)false |
