“…The lack of key trophic groups observed elsewhere may induce niche displacement; for instance, M. niger acting as the main roving herbivore foraging over the EAM. Moreover, niche expansion is also observed, as in the case of juveniles of Stegastes sanctipauli presenting an invertivore diet (Gasparini et al 2008). This extreme low functional redundancy may have undesirable consequences when overfishing occurs.…”

This study investigates the reef fish community structure of the world’s smallest remote tropical island, the St Peter and St Paul’s Archipelago, in the equatorial Atlantic. The interplay between isolation, high endemism and low species richness makes the St Peter and St Paul’s Archipelago ecologically simpler than larger and highly connected shelf reef systems, making it an important natural laboratory for ecology and biogeography, particularly with respect to the effects of abiotic and biotic factors, and the functional organisation of such a depauperate community. Boosted regression trees were used to associate density, biomass and diversity of reef fishes with six abiotic and biotic variables, considering the community both as a whole and segregated into seven trophic groups. Depth was the most important explanatory variable across all models, although the direction of its effect varied with the type of response variable. Fish density peaked at intermediate depths, whereas biomass and biodiversity were respectively positively and negatively correlated with depth. Topographic complexity and wave exposure were less important in explaining variance within the fish community than depth. No effects of the predictor biotic variables were detected. Finally, we notice that most functional groups are represented by very few species, highlighting potential vulnerability to disturbances.

“…As a result, oceanic islands are poorer in species richness and often contain more endemic species than continental shelves or islands (Robertson, 2001;Vermeij, 2004;Dawson, 2016). These particularities in isolated communities' species pools can also foster the emergence of unique behaviours and interactions, as has been documented for marine species at South Atlantic oceanic islands (Lubbock, 1980;Sazima et al, 2003Sazima et al, , 2007Sazima & Sazima, 2004;Gasparini et al, 2008). Some of these interactions can have important ecosystem-wide consequences, for example, by enhancing the energetic flux among trophic compartments in these species-depauperate systems (Sazima et al, 2003(Sazima et al, , 2006Sazima & Sazima, 2004).…”

“…There have been several studies on cleaning symbiosis, mob-feeding and nuclear-follower feeding interactions (opportunistic fishes that follow substrate-disturbing fishes), but most of these were conducted along coastal reefs, leaving oceanic islands woefully understudied (but see von Eibl-Eibesfeldt, 1955; Gasparini & Floeter, 2001; Sazima et al , 2007; Gasparini et al , 2008; Bertoncini et al , 2009). At Ascension island, particularly, knowledge on these interactions is restricted to mentions and pictures in Lubbock (1980); Bingeman & Bingeman (2005) and Wirtz et al (2014).…”

“…At Ascension island, particularly, knowledge on these interactions is restricted to mentions and pictures in Lubbock (1980); Bingeman & Bingeman (2005) and Wirtz et al (2014). As these isolated environments constitute evolutionary units on their own (Dawson, 2016), they might also be engines for the appearance of novel interactions among species, some with uninvestigated ecosystem consequences (Sazima et al , 2003, 2007; Sazima & Sazima, 2004; Gasparini et al , 2008). Therefore, our objective is to partially fill the gap that exists in our understanding of isolated islands in the Atlantic.…”

Isolated oceanic islands may give rise not only to new and endemic species, but also to unique behaviours and species interactions. Multi-species fish interactions, such as cleaning, following, mob-feeding and others are understudied in these ecosystems. Here we present qualitative and quantitative observations on cleaning and mob-feeding reef fish associations at the isolated Ascension Island, South Atlantic Ocean. Cleaning interactions were dominated by juveniles of the facultative fish cleanersBodianus insularisandPomacanthus paru, with lesser contributions ofChaetodon sanctaehelenae, Thalassoma ascensionisand the cleaner shrimpLysmata grabhami. Two types of feeding mobs were consistently identified: less mobile mobs led by the surgeonfishAcanthurus bahianusandA. coeruleusand the more mobile mobs led by the African sergeantAbudefduf hoefleri. This is the first record ofA. hoeflerifrom outside of the Eastern Atlantic and also the first report of this species displaying mob-feeding behaviour. The principal follower of both mob types was the extremely abundantMelichthys niger, but the main aggressor differed:Stegastes lubbocki, a highly territorial herbivore, was the main aggressor ofAcanthurusmobs; andChromis multilineataa territorial fish while engaged in egg parental care, was the principal aggressor towardsAbudefdufmobs. Our study enhances the scarce information on reef fish feeding associations at the isolated Ascension Island and at oceanic islands in the Atlantic in general.

This work reports for the first time cleaning activity by fish and shrimps in Santa Luzia, Cape Verde Archipelago and São Tomé Islands. Three new records of facultative cleaner fish species are presented. Facultative cleaners dominated by Labridae were the most observed cleaner fishes in the two studied islands. Multi-specific cleaning stations were prevalent in Santa Luzia, while cleaner shrimps were more observed interacting in the São Tomé Islands.
