“…Of this area, 26.4% is protected by 177 marine protected areas (MPAs), of which 73 are NTR representing 3.3% of the country’s marine waters [17]. However, the few studies available about the effects of Brazilian NTRs on fish assemblage are concentrated in the northern part [18], southern part [19, 20] or offshore islands [21, 22], with a lack a studies in the transition zones and small coastal NTR networks.…”

24No-take marine reserves (NTRs), i.e. areas with total fishing restrictions, have been 25 established worldwide aiming to provide biodiversity and ecosystem conservation. Brazil has 26 established NTRs, but currently lacks scientific knowledge and understanding of their 27 ecological role, particularly regarding rocky reefs in subtropical regions. Consequently, this 28 study aimed to contrast NTR, from the 30 year old Tupinambás Ecological Station, and 29 comparable fished sites across a coastal biogeographic gradient to investigate the effect of 30 fishing and habitat variability on the abundance and body-size of rocky reef fish. We used 31 Baited Remote Underwater stereo-Video (stereo-BRUVs) and Diver Operated stereo-Video 32 (stereo-DOVs) systems to simultaneously sample reef fish and habitat. Model selection and 33 results identified habitat and biogeographic variables, such as distance from shore, as important 34 predictor variables, explaining several aspects of the fish assemblage. The effect of protection 35 was important in determining the abundance and body-size of targeted species, in particular for 36 epinephelids and carangids. Conversely, species richness was correlated with habitat 37 complexity and not with protection status. This is the first study to publish data using these 38 novel survey methods in the Southeastern Atlantic and demonstrate their utility, in combination 39 with an established network of NTR's, to provide benchmarks for conservation and fisheries 40 management. 41 42 43 EventMeasure, GAM.46 47No-take marine reserves (NTRs) have been established worldwide as a management 48 strategy mostly aiming to recover marine biodiversity from effects of fisheries. It is well 49 documented that these areas can provide refuge to marine life, increasing local abundance, 50 species richness, body size and the reproductive capacity of fish [1][2][3][4]. 51Networks of NTRs can be used to investigate effects of fishing across biogeographic 52 gradients, with the aim of estimating benchmarks for conservation and fisheries management. 53Besides facing direct fisheries effects from biomass removal, NTRs have also highlighted 54 indirect effects, where the removal of large carnivores in areas without protection can result in 55 a higher abundance of prey species, leading to a trophic reorganization [5][6][7]. 56It is also well documented that fish assemblage structure will vary with physical, 57 chemical and biological factors across biogeographic and habitat gradients through space [8-58 10]. In particular, distance from the coast and topographic complexity have shown to increase 59 species richness, abundance and biomass of reef fish [11][12][13][14][15][16]. It is therefore important for any 60 investigation of the effects of fishing to be able to control for these covariates across any inside 61 versus outside NTR comparison. 62Brazil has 8500 km of coastline and a territorial sea that, together with the Exclusive 63 Economic Zone, encompasses 4 million km 2 . Of this area, 26.4% is protected by...

“…Moreover, deterministic mechanisms coupled with the evolutionary history (habitat affinity), habitat heterogeneity of rocky substrate availability (Anderson et al, 2019), cyclic seasonal temperature oscillations (Bernardes et al, 2018) and protection factor (e.g., E. marginatus and M. acutirostris) could also have influenced such patterns (Anderson et al, 2014(Anderson et al, , 2019Ault and Johnson, 1998;García-Charton et al, 2004;García-Charton and Pérez-Ruzafa, 2001).…”

“…Macrocarnivore (MCAR) biomass seems to vary in space according to fisheries restrictions in the MPA (Anderson et al, 2014(Anderson et al, , 2019Maggs et al, 2013;Mellin et al, 2016;Palumbi, 2004). The effectiveness of the MPA is evident, especially in protecting the old, large and furtive mothers (i.e., long-living individuals which can reach 50 years) (Palumbi, 2004;Reñones et al, 2002) (Figures 2 and 3).…”

“…This peculiar region, a transitional climatic zone influenced by both warm tropical waters from the Brazil Current and cool waters from the South Atlantic Central Water, is regarded as the "Arc of Capricorn" (Anderson et al, 2015). Recently, considerable effort has been made (Anderson et al, 2015(Anderson et al, , 2017(Anderson et al, , 2019Begossi et al, 2012;Hackradt et al, 2011), but most works have left a severe gap in regard to the temporal variations in marine populations. Moreover, the mechanisms responsible for temporal variation in reef fish density and biomass remain a matter of controversy and debate (Choat et al, 1988;Doherty, 2002).…”

Biogeographical transition zones are important areas to investigate evolutionary ecological questions, but long‐term population monitoring is needed to better understand ecological processes that govern population variations in such edge environments. The southernmost Brazilian rocky reefs are the southern limit of distribution for 96% of the tropical ichthyofauna of the western Atlantic. The Arvoredo Marine Biological Reserve is the only nearshore no‐take marine‐protected area (MPA) located in this transition zone. The main aim was to investigate how the populations of rocky reef fish species vary in density and biomass in space and over time, inside and outside the Arvoredo MPA. This study presents results based on a 9 year (2008–2017) underwater visual census monitoring study to evaluate the density and biomass of key fish species. Variations in density and biomass were detected for most species. Factors and mechanisms that may have influenced spatial variation are habitat structural complexity and protection from fisheries. Temporal variations, otherwise, may have been influenced by species proximity to their distributional limit, in synergy with density‐dependent mechanisms and stochastic winter temperature oscillations. The MPAs harbour higher density and biomass for most species. Nonetheless, a prominent temporal decline in the recruitment of Epinephelus marginatus calls into question the continuous effectiveness of the MPA.
