    Marine anthropogenic eutrophication from nutrient and metal inputs has been linked to shifts in reef communities, benefitting fast-growing organisms that can outcompete corals. In 2015, the collapse of a mining dam in Brazil containing iron (Fe) waste reached the Southwestern Atlantic (SWA) Ocean and adjacent environments, but its effects on competitive interactions of corals are still unknown. We assessed the impacts of seawater enrichment with dissolved Fe on benthic competition with three reef-building corals ( Siderastrea sp., Millepora alcicornis , Mussismilia harttii ) against a common macroalga ( Lobophora variegata ) and a zoantharian ( Palythoa caribaeorum ) in a mesocosm experiment. Organisms physically interacted while submitted to four Fe concentrations (0, 100, 300, and 900 μg L −1 ) for 26 days. We measured photosynthetic efficiencies of all organisms and recorded tissue discoloration and necrosis on corals. The photosynthetic efficiency of all corals reduced along time, regardless of Fe. When contacting macroalgae, Siderastrea sp. was least affected while Mi. alcicornis and Mu. harttii were damaged within the first days and suffered high discoloration. Mu. harttii underwent necrosis and dead areas were significantly larger at the highest Fe concentration. Contacts with the zoantharian caused discoloration in all corals and necrosis in Mu. harttii , without a clear effect of Fe. The concentration of Fe differentially impacted the studied species interactions, but did not cause negative effects alone. Our study shows the vulnerability of SWA corals considering future increases in the abundance of benthic competitors and the consequences for corals following mining disasters, helping to predict the impacts of iron enrichment on reefs. • Anthropogenic stressors can affect the outcome of competitive interactions. • We evaluated the effects of Fe on corals competing with macroalgae and zoantharians. • Competition was detrimental to all corals analyzed. • High Fe concentration led to greater necrosis in an endemic coral while competing. • Results help understand consequences for corals following a contamination event.

    In 2015, a marine mesocosm facility was designed and implemented by the Coral Vivo Project in its research station (Porto Seguro, Bahia State, Brazil) to initially study the effects of global impacts, especially ocean warming and acidification, on coral reefs. However, local impacts, including seawater contamination with metal(loid)s, are considered as a major threat to coral reefs. Also, in 2015, the largest disaster involving a mining dam occurred in Brazil. Iron (Fe) mining tailings originated from the dam failure affected not only freshwater ecosystems (rivers, lakes and lagoons), but also adjacent beaches, mangroves, restingas, reefs and other marine systems. Seawater, sediments and biota were contaminated with metal(loid)s, especially Fe, arsenic (As), mercury (Hg) and manganese (Mn). Therefore, we aimed to adapt the marine mesocosm facility of the Coral Vivo Project to evaluate the bioaccumulation and biological impacts of increasing concentrations of dissolved Fe on a diversity of reef organisms. Results obtained indicate a great versatility and reliability of the marine mesocosm system for application in biological and ecological studies on the isolated effect of seawater dissolved Fe on reef organisms of different functional groups simultaneously. • Studies involving seawater enrichment with dissolved Fe can be performed using a marine mesocosm system. • The marine mesocosm is a reliable tool to study the isolated effects of metal(loid)s on reef organisms.

    Corals are colonial animals within the Phylum Cnidaria that form coral reefs, playing a significant role in marine environments by providing habitat for fish, mollusks, crustaceans, sponges, algae, and other organisms. Global climate changes are causing more intense and frequent thermal stress events, leading to corals losing their color due to the disruption of a symbiotic relationship with photosynthetic endosymbionts. Given the importance of corals to the marine environment, monitoring coral reefs is critical to understanding their response to anthropogenic impacts. Most coral monitoring activities involve underwater photographs, which can be costly to generate on large spatial scales and require processing and analysis that may be time-consuming. The Marine Ecology Laboratory (LECOM) at the Federal University of Rio Grande do Norte (UFRN) developed the project “#DeOlhoNosCorais” which encourages users to post photos of coral reefs on their social media (Instagram) using this hashtag, enabling people without previous scientific training to contribute to coral monitoring. The laboratory team identifies the species and gathers information on coral health along the Brazilian coast by analyzing each picture posted on social media. To optimize this process, we conducted baseline experiments for image classification and semantic segmentation. We analyzed the classification results of three different machine learning models using the Local Interpretable Model-agnostic Explanations (LIME) algorithm. The best results were achieved by combining EfficientNet for feature extraction and Logistic Regression for classification. Regarding semantic segmentation, the U-Net Pix2Pix model produced a pixel-level accuracy of 86%. Our results indicate that this tool can enhance image selection for coral monitoring purposes and open several perspectives for improving classification performance. Furthermore, our findings can be expanded by incorporating other datasets to create a tool that streamlines the time and cost associated with analyzing coral reef images across various regions.

  • Trophic interactions will expand geographically but be less intense as oceans warm

    Global Change Biology, 2020
    Interactions among species are likely to change geographically due to climate‐driven species range shifts and in intensity due to physiological responses to increasing temperatures. Marine ectotherms experience temperatures closer to their upper thermal limits due to the paucity of temporary thermal refugia compared to those available to terrestrial organisms. Thermal limits of marine ectotherms also vary among species and trophic levels, making their trophic interactions more prone to changes as oceans warm. We assessed how temperature affects reef fish trophic interactions in the Western Atlantic and modeled projections of changes in fish occurrence, biomass, and feeding intensity across latitudes due to climate change. Under ocean warming, tropical reefs will experience diminished trophic interactions, particularly herbivory and invertivory, potentially reinforcing algal dominance in this region. Tropicalization events are more likely to occur in the northern hemisphere, where feeding by tropical herbivores is predicted to expand from the northern Caribbean to extratropical reefs. Conversely, feeding by omnivores is predicted to decrease in this area with minor increases in the Caribbean and southern Brazil. Feeding by invertivores declines across all latitudes in future predictions, jeopardizing a critical trophic link. Most changes are predicted to occur by 2050 and can significantly affect ecosystem functioning, causing dominance shifts and the rise of novel ecosystems.
