13. Influence of Palythoa caribaeorum (Anthozoa, Cnidaria) zonation on site-attached reef fishes
Este estudo visou testar a influência de Palythoa caribeorum, um zoantídeo amplamente distribuído no Atlântico, na estruturação da comunidade de peixes recifais associados a um costão rochoso de uma região subtropical. A densidade, a riqueza e a distribuição vertical de peixes recifais em áreas previamente selecionadas com e sem a dominância de P

16. Caracterização ecológica dos peixes recifais do Atol das Rocas
The present work was carried out at the Atol das Rocas (3 51 S; 33 49 W), the only atoll of the South Atlantic and the first Brazilian marine protected area. It was guided by the following hypothesis: the composition of the fish communities varies in agreement with the position of the pools; in other words, with or without permanent ocean connection. To test

17. Atividade de forrageamento de tres especies sintopicas de Sparisoma (Perciformes: Scaridae) no Arquipelago de Fernando de Noronha, Pernambuco / Foraging of three syntopic species of Sparisoma (Perciformes: Scaridae) at Fernando de Noronha Archipelago, tropical western Atlantic
Parrotfishes are important components of the herbivore and detritivore guilds of tropical and subtropical reefs. These fishes are protogynous hermaphrodites which change colour and sex, from initial phase females or males (IP) to terminal phase males (TP). The foraging of Sparisoma amplum, S. axillare and S. frondosum was studied at Fernando de Noronha Archi

18. Idade, crescimento e uso do habitat das espÃcies Stegastes rocasensis, no Atol das Rocas e Stegastes sanctipauli, no ArquipÃlago de SÃo Pedro e SÃo Paulo
Although the importance of coral reef environments, it is known by scientists all around the world that this ecossistem is actually under potencial impacts and declining. A vital part of coral reefs ecossistems is composed by coral reef fishes. It is estimated that 30-40% of marine fishes can be found in coral reefs. The Pomacentridae family has an important

19. Multiple pericentric inversions and chromosomal divergence in the reef fishes Stegastes (Perciformes, Pomacentridae)
Damselfishes (Pomacentridae, Perciformes) occur in all major oceans of the world and, with approximately 320 species, represent one of the most diverse families of marine Teleostei. The taxonomy of these reef fishes is problematic because of the large number of complex species and the range of color patterns they display, which vary among individuals and pop

20. AnÃlise das incertezas das estimativas dos parÃmetros de crescimento e mortalidade utilizados na avaliaÃÃo de estoques de peixes recifais no Nordeste do Brasil
O manejo pesqueiro, tradicionalmente, baseia-se em modelos de avaliaÃÃo de estoque objetivando indicar recomendaÃÃes para a explotaÃÃo Ãtima de uma determinada espÃcie, sem que ocorra o colapso desta. Os modelos de avaliaÃÃo de estoque requerem em seus cÃlculos dados biolÃgicos da populaÃÃo provenientes dos parÃmetros de crescimento e das taxa

21. Larvas de peixes e invertebrados planctÃnicos coletados com um novo modelo de armadilha de luz: Bahia de Tamandarà - PE
Larval fish and a great number of other planktonic organisms, display photobehavioral characteristics which make possible the use of artificial li-t to attract and capture them. The concept of light traps is not a new concept, and it has been used for a long time by entomologists and limnologists, but introduced to stud reef enviroment by Doherty in 1987. Th

22. Potencial atrator de peixes ósseos em recife artificial no litoral norte do estado do Rio de Janeiro, Brasil
Artificial reefs have become an important and popular resource enhancement technique by concentrating fishes and by increasing natural production of biological resources. In order to increase the necto-benthic colonization potencial, an artificial reef was installed on the northern coast of Rio de Janeiro (21º27'S, 41ºOO'W), an area with typically low reli

23. Population maintenance among tropical reef fishes: Inferences from small-island endemics
To what extent do local populations of tropical reef fishes persist through the recruitment of pelagic larvae to their natal reef? Endemics from small, isolated islands can help answer that question by indicating whether special biological attributes are needed for long-term survival under enforced localization in high-risk situations. Taxonomically and

24. Ockham's razor gone blunt: coenzyme Q adaptation and redox balance in tropical reef fishes
The ubiquitous coenzyme Q (CoQ) is a powerful antioxidant defence against cellular oxidative damage. In fishes, differences in the isoprenoid length of CoQ and its associated antioxidant efficacy have been proposed as an adaptation to different thermal environments. Here, we examine this broad contention by a comparison of the CoQ composition and its redox s
