Impactos ambientais sobre o manguezal de Suape - PE

Abstract: A zona estuarina de Suape é formada pelos rios Massangana, Tatuoca, Ipojuca e Merepe, situando-se a cerca de 25km ao sul do Recife. A implantação um porto e da infra-estrutura para um complexo industrial acarretou em obras de aterros, dragagens e represamentos, alterando a hidrologia local e modificando drasticamente a paisagem. A partir de fotografias aéreas na escala 1:30.000 obtidas nos anos de 1974 e 1988, de imagens do sensor TM do satélite Landsat 5 de 1984 e com o auxílio de carta topográfica na escala … Show more

“…Stable isotope measurements have shown that an amount of 13% to 40% of the carbon assimilated by estuarine copepods was of mangrove origin. In Suape Bay however, the destruction of 600 hectares of mangrove (Braga et al, 1989) affected the availability of organic detritus, thus limiting another food source for the zooplankton. Brachyuran zoeae, fish larvae and eggs were very abundant at the Suape area before port implantation (Paranaguá, 1986), but nowadays, although frequent in the rainy season, they occurred in low abundances, showing a deficiency in larval recruitment.…”

“…A carga orgânica de nove cidades da bacia, bem como o potencial poluidor foi estimado em 21.861 kg DBO.dia -1 , para 1990( CPRH 1995. No que se refere a vegetação Braga et al (1989) mencionaram que o manguezal sofreu um processo de degradação acentuado, decorrente de aterros, dragagens e represamentos com a implantação do porto, com cerca de 600 hectares destruídos.…”

“…The study area off Recife corresponds to a seashore with heterogeneous bathymetry included in a region with many estuaries and mangrove habitats, which urban development depleted to a great extent (Braga, Uchoa & Duarte, ). The sudden shark attack outbreak coincided with the nearby construction of a commercial port (Hazin et al ., ), suggesting that anthropogenic disturbance may have increased the probability of sharks encountering and interacting with bathers and surfers.…”
