“…When we simulated the loss of threatened vertebrate species ( n = 63; 28.12%), we found that such loss may compromise the regional functional space (60.1%). Most of these threatened species share a macrocarnivore diet and large body sizes, which have been investigated in previous studies as predictors of extinction risk for fish and marine mammal species (Bender et al., 2013; Ceretta et al., 2020; Dulvy & Reynolds, 2002; Dulvy et al., 2003). Sharks are the majority of top predator species in Atlantic reefs (87.5%) and are largely threatened (46%).…”

“…marine megafauna), habitat specialists and species with terrestrial contact (e.g. sea turtles and pinnipeds; Ceretta et al., 2020; McCauley et al., 2015; Pimiento, Leprieur, et al., 2020). Nevertheless, the influence of declines and changes in biodiversity on ecosystem functions such as productivity, nutrient cycling and trophic regulation still needs to be better understood (Bellwood et al., 2019; Fonseca & Ganade, 2001; Larsen et al., 2005; Levine, 2016; Mouillot et al., 2014).…”

“…Such characteristics have contributed to the threatened status of many grouper species worldwide [15,92]. The decline of other predator species as C. hippos and S. fasciata is concerning, since these species are important regional fishing resources [93], and as expected for large carnivores, depict a combination of biological traits that can enhance their extinction risk [94].…”

An understanding of the effects of fishing on marine ecosystems relies on information about the conserved state of these environments. Non-conventional approaches such as the use of historical data and local ecological knowledge can provide information and help adjust our references of changes in the environment. Also, the combination of different types of data can indicate a fisheries trend that would be undetectable when evaluated separately. Here we investigated changes in fisher’s perceptions regarding overexploited and new target species in artisanal fisheries in a secular fishing village of the subtropical, southeastern Brazilian coast. We identified temporal changes in landings and in the mean trophic level (MTL) of high trophic level species (≥ 3.5 and >4) over 16 years. Fishers’ knowledge revealed shifts in perception associated with years of fishing practice. More experienced fishers recognized a greater number of overexploited and new target species than fishers in the beginning of their careers. Landing data has revealed declining trends of 72% for five mesopredators species. Due to the overfishing of mesopredators, there was a shift in target species, towards fish that were previously discarded. Temporal changes in landings and in the MTL metric are concordant with previous reports on the overexploitation of species caught by local fishers. Our work reveals that multiple sources of information can be combined to establish historical baselines and improve the detection of change in marine ecosystems.

“…For instance, species richness correlates strongly and positively with mean sea surface temperature (SST), whereas the latter has limited effect on functional diversity (Stuart-Smith et al 2013, Quimbayo et al 2019. Further, anthropogenic factors can also influence taxonomic richness and trait composition because of differential vulnerability among communities (Dornelas et al 2014, Ceretta et al 2020. Human density and accessibility to fish markets, for instance, can have a negative effect mainly on top predators and large herbivores on coral reefs (Cinner et al 2016(Cinner et al , 2018.…”

A core challenge in ecology is identifying the factors that determine species distribution and functional diversity of species assemblages. Reef fish are the most diverse group of vertebrates, form taxonomically rich and functionally diverse communities and represent a key source of food for humans. We examine regional distribution patterns of reef fish species richness and functional diversity and investigate how these are determined by historical, biogeographic, energetic, and anthropogenic factors. We compiled data from 3,312 underwater visual censuses performed at 122 locations comprising rocky and coral reefs along the Eastern Tropical Pacific (ETP). We used generalized linear mixed‐effects models (GLMMs) implemented in a Bayesian framework to investigate whether distance from quaternary refugia, distance from mainland, shelf area, primary productivity, sea surface temperature (SST), human population gravity, and conservation status influence reef fish species richness and functional diversity in the ETP. Species richness and functional richness (FRic) peaked towards the center of the ETP and our null model suggests that FRic followed a spatial pattern that would be predicted by species richness. Additionally, functional evenness (FEve) was highest at higher latitudes whereas functional dispersion (FDis) was homogeneous throughout the ETP. Species richness was negatively influenced by shelf area and distance from mainland, but positively influenced by SST and conservation status. FEve was influenced by human population gravity and FDis by shelf area. Reef fish species richness and functional diversity in the ETP exhibited a strong division within the region mainly mediated by SST and human population gravity. Our results also suggest that dominant species within small shelf areas share more common traits than dominant species in large areas. This study uncovers previously unknown regional patterns of reef fish functional diversity and provides new insights into how historical, biogeographic, energetic, and anthropogenic factors influence complementary biodiversity facets.
