Approximately 60% of coral reefs are currently threatened by several natural and anthropogenic impacts. One
of the fastest growing industries in the world and a great producer of organic waste, tourism can have negative impacts on biodiversity and on the functioning of reef ecosystems. This study aimed to find possible anthropogenic impacts related...
Among the marine invertebrate groups recorded from oceanic islands, bryozoans stand out because they can live and reproduce in suboptimal habitats, which may enhance their dispersal capabilities. This study aimed to update the check- list of bryozoans known from the Saint Peter and Saint Paul Archipelago (ASPSP) and discusses their distribution. Du...
This article reviews the literature involving benthic invertebrates that are cited in association with hull fouling, reporting the species that occur on the Brazilian coast and evaluating the importance of this vector for the introduction of nonindigenous and cryptogenic invertebrates in Brazil. It discusses some of the strategies that were used by...
Shipwrecks are considered artificial reef environments - structures immersed in aquatic environments (especially marine ones) that provide fauna with shelter, hard substrates, food and nursery areas. This study aimed to survey the benthic animal biodiversity of the Pirapama shipwreck, located 23 m deep and six miles off Recife harbor. From 2001 to...
Despite their ecological and social-economic importance, coral reefs are under constant threat and thus require proper management practices. Data on the spatial structure of these ecosystems are essential for good quality conservation projects in such areas. This study aimed to quantitatively analyze the spatial distribution of benthic macroorganis...
The fauna that inhabits artificial reef environments such as shipwrecks is part of a biological community that cannot be neglected. This study aimed to uncover the benthic animal biodiversity of the Servemar X and Vapor de Baixo shipwrecks, located on the coast of Pernambuco State, Brazil, to reveal the importance of these artificial environments f...
Long-term monitoring program of organisms is the most recommended for understanding changing processes on reefs. The video transect method presents advantages for that. Specialists state that it is important to make sure that the recorded coverage is always the same between campaigns, so that differences in results may be entirely attributed to env...
The Fernando de Noronha Archipelago (Pernambuco State, Brazil), a national marine park, is formed by 21 islands and islets of volcanic origin. An update of the checklist of the benthic cnidarians from some of the archipelago's reef environments, as well as a study of their corals and calcified hydroids morphometry, was the major goal of this work....

Introdução Os recifes de profundidade são conhecidos desde o Século XVIII; tendo os cnidários pertencentes à Ordem Scleractinia (corais pétreos) apontados como contribuintes importantes de sua construção [1,2,3,4]. Nestes ambientes, desenvolvem-se fluxos de matéria e energia por mecanismos diferentes daqueles ocorrentes em recifes comuns. Contudo,...
RESUMO: A sistemática dos corais escleractínios está tradicionalmente baseada na morfologia esquelética. Todavia, uma mesma espécie de coral pode apresentar uma ampla gama de variações morfológicas, gerando assim muitas incertezas taxonômicas. Com o objetivo de investigar a variação no esqueleto de duas espécies de corais, Favia gravida e Siderastr...
Here we present a first record of widespread coral bleaching off the northern coast of Brazil, in the Manuel Luiz Marine State Park. During an expedition to find cnidarians in June 1998 high scleractinian and calcified hydroid diversity was encountered, a richness that in Brazil can only be compared to the Abrolhos, Bahia State): four species of ca...
Most of the Brazilian coast has reef environments, important ecosystems from both the ecological and human viewpoints, yet under a continuous process of degradation. An instrument that can be used to halt threats to these ecosystems is environmental education (and one of the best places to use it is at school), but environmental perception studies...
