Branqueamento de corais nos recifes da Bahia e sua relação com eventos de anomalias térmicas nas águas superficiais do oceano

Abstract: . 2008. Coral bleaching in Bahia reefs and its relation with sea surface temperature anomalies. Biota Neotrop. 8(3): http://www.biotaneotropica.org.br/ v8n3/en/abstract?article+bn00808032008.Abstract: Since 1993 several coral bleaching events were registered in Bahia. There were no mass coral death associated to these events and the affected corals fully recovered after the impact. The first occurrence was registered during the southern hemisphere summer of 1993/1994, in Abrolhos, when 50 to 90% of the coral c… Show more

“…However, this hypothesis needs to be tested. Positive thermal anomalies of up to 0.75 °C were recorded during the summer, between 1998 and 2005, in Bahia State (including the Porto Seguro area), resulting in different degrees of mild to severe bleaching (LEÃO et al, 2008). The presence of thermal-tolerant endosymbionts may be fostered by such anomalies (see BAKER et al, 2004).…”

“…Among the six endemic species in Brazil is Mussismilia harttii (VERRILL, 1868), distributed from the State of Rio Grande do Norte to the state of Espírito Santo, in addition to the islands of Fernando de Noronha and Atol das Rocas (LEÃO et al, 2008). The reef-builder corals of Brazil coexist with a highly terrigenous environment.…”

“…At approximately 17ºS, the continental shelf widens to form the Abrolhos Bank on which the richest and best known coral reefs of the eastern Brazilian region are located (HARTT, 1870;LABOREL, 1970, LEÃO, 1983LEÃO et al 1988, LEÃO et al, 1996, 1999GINSBURG, 1997;PITOMBO, 1997;PITOMBO et al, 1988;KIKUCHI, 2001;LEÃO et al, 2003LEÃO et al, , 2006FOURNIER, 2007;LEÃO et al, 2008;FRANCINI-FILHO et al, 2008among others). These reefs form the following two arcs: the coastal arc composed of bank reefs of various shapes and dimensions and the outer arc eastward of the islands of the Abrolhos Archipelago, which is formed by isolated "chapeirões" in water deeper than 20 m. Incipient fringing reefs border the shores of the five islands that compound the archipelago (Figures 9 and 10).…”

“…Na costa leste já existem levantamentos sistemáticos desde o ano de 2000. Todos esses registros indicam que a ocorrência de branqueamento dos corais, no Brasil está relacionada a um aumento anormal da temperatura das águas oceânicas (Migotto, 1997;Castro & Pires, 1999;Dutra, 2000;Costa et al, 2001, Costa et al, 2004Ferreira & Maida, 2006;Leão et al, 2008Leão et al, e 2010Kelmo & Atrill, 2013). A avaliação dos efeitos das variações climáticas sobre a comunidade recifal do Brasil é uma das metas da ReBentos, e uma das estratégias mais utilizadas para medir esses efeitos é avaliar o branqueamento dos corais durante e após a ocorrência de eventos de anomalias térmicas das águas oceânicas.…”

“…A distribuição dos recifes ocorre desde os bancos do parcel de Manuel Luiz, no Estado do Maranhão (Amaral et al, e 2008, passando a importantes áreas ao longo do litoral dos estados do Ceará, Rio Grande do Norte, Paraíba, Pernambuco, estendendo-se até o sul da costa do estado de Alagoas, próximo à foz do rio São Francisco (Laborel, 1970;Testa, 1997;Castro & Pires, 2001;Ferreira & Maida, 2006;Santos et al, 2007;Correia, 2011;Correia & Sovierzoski, 2013). Pequenas formações recifais ocorrem costa afora no estado de Sergipe (Neves et al, 2005), bancos recifais isolados são encontrados no litoral norte do estado da Bahia (Nolasco & Leão, 1986;Kikuchi & Leão, 1997;Kikuchi, 2000;Kelmo & Attrill, 2001) e recifes bem desenvolvidos estendem-se ao longo de toda a costa do estado até a região de Abrolhos, onde estão os maiores e mais ricos recifes de corais de todo o oceano Atlântico Sul Ocidental (Hartt, 1870;Laborel, 1970;Hetzel & Castro, 1994;Pitombo et al, 1988;Castro et al, 2006;Kikuchi et al, 2003;Leão et al, 2003;Prates, 2006;Leão et al, 2008;. Várias formações recifais ocorrem na Zona Econômica Exclusiva (ZEE), incluindo o Atol das Rocas (Kikuchi, 1994(Kikuchi, e 2002Maÿal & Bezerra, 1995;Maida et al, 1997;Gherardi & Bosence, 1999e 2001Kikuchi, 2002;Pereira et al, 2010;Soares et al, 2011aSoares et al, e 2011b, Fernando de Noronha (Maida et al, 1997;Castro & Pires, 2001;…”
