1. Influência da composição de substrato do recife na atividade e distribuição de peixes zoobentívoros no arquipélago de Fernando de Noronha, Pernambuco / The influence of substratum composition on the activity and distribution of benthic carnivorous reef fishes of the Fernando de Noronha Archipelago
Reefs provide shelter and food for several fish species and, thus, there may be a correlation between the abundance and behaviour of fishes and the reef bottom composition-Physical factors, such as water movement and depth, may also have a profound impact in species distribuiton and activity on reefs. Here, the possible relationship between the distribution

2. DistribuiÃÃo de recrutas e adultos de cinco espÃcies de peixes recifais do Atol das Rocas / Distribution of recruits and adults of five species of reef fishes of the Rocas
O sucesso no recrutamento de peixes recifais depende do nÃmero de indivÃduos que sobrevivem apÃs a entrada das larvas no ambiente recifal. Diversos processos pÃs-recrutamento sÃo responsÃveis pela distribuiÃÃo de recrutas e adultos e, conseqÃentemente, pela estruturaÃÃo da populaÃÃo destes. A partir da realizaÃÃo de censos visuais subaquÃtico

5. 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

6. 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

7. Small-scale field experiments accurately scale up to predict density dependence in reef fish populations at large scales
Field experiments provide rigorous tests of ecological hypotheses but are usually limited to small spatial scales. It is thus unclear whether these findings extrapolate to larger scales relevant to conservation and management. We show that the results of experiments detecting density-dependent mortality of reef fish on small habitat patches scale up to have

8. Mimicry, colour forms and spectral sensitivity of the bluestriped fangblenny, Plagiotremus rhinorhynchos
Animals change their body coloration for a variety of purposes including communication, thermoregulation and crypsis. The cues that trigger adaptive colour change are often unclear, and the role of colour vision remains largely untested. Here, we investigated the bluestriped fangblenny (Plagiotremus rhinorhynchos), an aggressive mimic that changes its body c

9. Mass mortality of a Caribbean sea urchin: Immediate effects on community metabolism and other herbivores
The echinoid Diadema antillarum Philippi was an important herbivore in many areas of the Caribbean prior to the mass mortality that eliminated 95-99% of the individuals throughout the Caribbean in 1983-84. Five days after the mass mortality in St. Croix, U.S. Virgin Islands, algal biomass increased by 20% and algal community primary productivity dropped on b
