Full-text available
Recreational scuba diving is rapidly increasing, and the negative impacts to marine reef biota are of conservation concern. Educational approaches have been tested to mitigate diver damage to benthic organisms, but logistical constraints impede their implementation in many locations. We investigated the behaviors of scuba divers in terms of their c...

1. Recreational diving is a concern regarding its effects on benthic assemblages, especially on heavily dived coral reefs. However, spearfisher behaviour and the scale of damage they cause to corals remains unknown. 2. The behaviour of recreational spearfishers was observed to verify their rate of physical contacts on corals in the Abrolhos Bank,...
Article
Full-text available
Increasing exploitation effort and efficiency have been leading to population declines and extinctions among large marine animals. Understanding the magnitude of such losses is challenging because current baselines about species’ abundances and distributions in the sea were mostly established after humans had started affecting marine populations. F...
Article
Full-text available
The physical damages to benthic organisms caused by boat anchorages were assessed in the Arraial do Cabo Marine Extractive Reserve (ACMER), Brazil. It is one of the most visited scuba diving sites along the southwestern Atlantic. Through underwater visual observations, we analyzed if benthic organisms were damaged by anchors and/or anchor cabling a...
Article
Marine Protected Areas (MPAs) have been one of the main strategies for the conservation of marine ecosystems and an attempt to buffer or revert anthropogenic and natural disturbances. However, only the implementation of an MPA does not guarantee effectiveness in the maintenance of these environments. The involvement of the stakeholders in the whole...
Article
Faced with the need for isolation of most people to reduce the transmission of COVID-19, a great concern for the well-being of the population has resurfaced. Considering the numerous benefits of outdoor activities to human health and well-being, we assessed whether the quality of the experience of recreational divers in a marine protected area (MPA...
Article
Subtropical reefs have suffered from increasing threats and impacts mainly from anthropogenic activities. These reefs also have socioeconomic relevance being in many locations an important income source through recreational activities. This study aimed to assess the potentially damaging behaviors of scuba divers on benthic reefs organisms in the fi...
Article
The dog snapper, Lutjanus jocu, is a commercially exploited fish throughout the Brazilian Province (BP) and has been facing overexploitation. However, there are no systematized data on the species to date, which hinders management strategies for mitigating this scenario. In this review, we gathered the existing literature information on L. jocu alo...
Article
Scuba diving is a form of ecotourism that has demonstrably negative impacts on benthic sessile organisms through diver-induced mechanical damage, but we know relatively less about the direct and indirect impacts of divers on fishes and the communities they live in. Damselfishes (Pomacentridae) are an ideal model to study to understand the effects o...
Preprint
Spearfishing is practiced by a small fraction of younger recreational fishers and has received considerably less scientific attention than angling. This knowledge gap may negatively affect the ability for developing sustainable marine recreational fisheries. We address this through a global systematic review of the literature pertaining to marine s...
Article
Subtropical Brazilian reefs are commonly composed by rocky frameworks with low coral abundance. Contrarily to most tropical reefs, our knowledge on coral assemblages in subtropical reefs is still developing. Queimada Grande is a subtropical island in the Brazilian coast lying 35 km offshore from the state of São Paulo (24ºS). Despite the partial pr...
Article
Spearfishing is a popular activity practiced for recreation and subsistence along the tropical and subtropical coast of Brazil. Although being an economically important activity, the influence of species traits driving target preferences among recreational spearfishers have been poorly explored. Spearfishing is highly selective towards large trophy...
Article
Marine protected areas (MPAs) represent a useful tool for resource management, as well as to conserve and/or restore biological communities. The level of protection is key factor influencing the marine biodiversity, where a more enforced protection is expected to drive positive outcomes. In 2008, a large MPAs network ( 11,380 km 2) was established...
Article
Full-text available
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...
Article
Full-text available
Overfishing is notorious for triggering population collapses and disrupting marine biological functioning worldwide. To counter such a threat, policy-makers have created and implemented multiple management strategies, but most were incapable to prevent the decline of several key species. Here, we discuss a new management strategy in force since Jun...
Article
Assessing species conservation status and population trends is challenging especially on low and low-middle income countries mostly due to high costs. Therefore, long-term information about species gained through local ecological knowledge, can reveal threatening and overexploitation scenarios aiming to generate information for extinction risk redu...
Article
On tropical reefs, cleaning interactions, in which a fish or shrimp cleaner removes ectoparasites from a client fish, are common. Such cleaning interactions have been shown to reduce physiological stress in the clients. We asked whether the process of cleaning by a cleaner wrasse Thalassoma noronhanun modified a fish client's risk assessment, hypot...
Article
Sustainability of scuba diving tourism should be assessed not only in environmental terms, but also concerning the quality of the diving experiences. Through the application of semi-structured questionnaires, we assessed differences in the scuba diving experiences from three subtropical Brazilian marine protected areas (MPAs) with different context...
Article
Full-text available
The assessment of species conservation status traditionally relies on population data. In the absence of such data, biological attributes have been applied to predict the degree of species’ vulnerability. Our study investigated the accuracy of biological attributes to predict species’ vulnerability to extinction by contrasting matches and mismatche...
Article
Recreational diving is an expanding branch of ecotourism that when poorly managed, may cause considerable impacts to benthic organisms. Such impacts become a matter of concern in popular diving destinations. A systematic literature review was used to verify the characteristics of divers who cause damage to reefs, the effects on benthic organisms, a...
Article

Ecologically important marine ecosystems should be identified and protected, as is the case of the poorly known SW Atlantic rhodolith beds. Understanding the main variables predicting biodiversity patterns is essential for determining priority areas for conservation. Here, we analyzed the macroinvertebrate associated with rhodoliths from euphotic a...
Article
Recreational fishing is an important economic and social activity in many countries. However low- and middle-income nations often lack basic data, like catch recording, on this fishery. To gather data to better understand recreational spearfishing catch in Abrolhos Bank, we assessed images posted on Facebook between June 2014 and January 2015. We d...
Article
1. Increasing evidence has revealed that different fisheries have collapsed around the world. This is generally more evident in countries that can maintain long-term research and fisheries monitoring. When monitoring data are not available, alternative approaches to assess fisheries trends can be used, such as the local ecological knowledge of fish...

Full-text available
We investigated the feeding rates, agonistic behaviour and diet of two blenny species, Entomacrodus vomerinus and Ophioblennius trinitatis, by direct observation and gut content analysis. Both species coexist in small and shallow tide pools in the St Peter and St Paul's Archipelago, equatorial North Atlantic Ocean. The feeding rate of O. trinitatis...
Article
The reduction or loss of antipredator behavior is expected for animals isolated on islands, but most of studies have focused on terrestrial rather than aquatic species. Two different processes may modulate fish antipredator behavior in the waters off remote archipelagos. First, places with low human density may have reduced fishing pressure. Second...
Article
The assessment of management effectiveness is essential to measure how well marine protected areas (MPAs) are achieving their goals and objectives. Incorporating the view of multiple stakeholders is an important component of MPA planning and management as it may simultaneously help reduce conflicts and increase adherence to rules and compliance. Ho...
