No. of bitstreams: 1 KarllaMSLC.pdf: 1651302 bytes, checksum: c8e051c662b1016f7e8abeaff047c73b (MD5) Previous issue date: 2008-12-12 / The physical and environmental factors presented by each habitat and the rhythm of behavior patterns strongly influence the ecology and behavior of the all living beings. At same time this factors may provide clues about the structure of a population and its ecological balance. The organizational structure, ecology and behavior of a species appraised in a region if we know be in balance when compared to the same type of appraisal made in a degraded area can provide a clear view of how the anthropogenic influences acted on these species and what steps can be taken in order to mitigate the effects and keep the population. The region where this study was conducted is, like most areas of port, subject to intense physical and environmental degradation. With the emerging interest of change in the quality of these environments also by the companies themselves that use the port services, the proposed study aimed to characterize the use of habitat, the distribution of behavioral activities carried out throughout the day and influence of geomorphology of the bed, depth and variation of tide on the expression of the behavior of Sotalia guianensis in the port of Maceio - Alagoas. From this information will be possible establish parameters for comparison with other populations of S. guianensis and establish conservation measures for the population occurring in the port of Maceio - AL, serving also as a basis for conservation actions future performed in other port regions / Os fatores f?sicos e ambientais apresentados por cada h?bitat e a ritimicidade dos padr?es comportamentais influenciam fortemente a ecologia e o comportamento dos seres vivos em geral. Ao mesmo tempo tais fatores podem fornecer pistas sobre a estrutura de uma popula??o e seu equil?brio ecol?gico. A estrutura organizacional, ecol?gica e comportamental de uma esp?cie avaliada em regi?es sabidamente em equil?brio quando comparada ? mesma avalia??o feita em ?reas degradadas pode fornecer um panorama claro de como as influ?ncias antr?picas agiram sobre estas esp?cies e que medidas podem ser tomadas no intuito de mitigar os efeitos nocivos e conservar a popula??o. A regi?o onde foi realizado esse estudo est?, assim como a maioria das ?reas de porto, sujeita ? intensa degrada??o f?sica e ambiental. Com o interesse emergente de mudan?a na qualidade desses ambientes por parte tamb?m das pr?prias empresas que utilizam os servi?os portu?rios, o estudo proposto visou caracterizar o uso do habitat, a distribui??o das atividades comportamentais realizadas ao longo do dia e a influ?ncia da geomorfologia do fundo, profundidade e das varia??es da mar? sobre a express?o dos comportamentos de Sotalia guianensis na regi?o do Porto de Macei? Alagoas. A partir dessas informa??es ser? poss?vel estabelecer par?metros para compara??o com outras popula??es de S. guianensis e delinear medidas de conserva??o para a popula??o ocorrente no Porto de Macei? AL, servindo ainda como base para a??es de conserva??o futuramente executadas em outras regi?es portu?rias
