The analysis reveals the need to comprehend these factors in order to create well-informed conservation approaches, and it also highlights knowledge gaps about how virulence variables affect coral health. It emphasizes the ecological implications of biofilm dynamics, showing how they impact pathogen defense, nutrient cycling, and the overall health of coral ecosystems. This review emphasizes the critical issue of the interplay between biofilm formation, environmental stress, and virulence dynamics, and the need for specialized conservation techniques.

While an increased body of evidence is documenting the negative effects of ocean acidification, most of these studies are still based on short-term exposure. Long-term experiments, studying multiple traits simultaneously, and accounting for short-term local pH variability in the species' habitat are needed. This study investigated the impact of a 310-day exposure to low pH on the banded-dye murex, <i>Hexaplex trunculus</i> (Linnaeus, 1758), a predatory Mediterranean gastropod. Temperature strongly influences the behavior and activity of the banded-dye murex, so we allowed it to vary naturally in this experiment. Our results showed that the net calcification rate was negatively affected by low pH throughout the duration of the experiment. While the banded-dye murexes were able to maintain their total body weight at the beginning of the experiment, it decreased under chronic exposure to low pH. Soft tissue body weight remained unaffected for more than 200 days, followed by a pronounced decrease when exposed to lower pH. No sex-specific differences in response to low pH were observed, but females generally exhibited higher rates of calcification and growth during the winter period, likely due to energy allocation strategies associated with the reproductive cycle. These results suggest that while the banded-dye murex can temporarily reallocate energy to maintain essential physiological functions under low pH, this capacity diminishes over time, revealing physiological limits to long-term stress tolerance. This finding highlights the importance of incorporating long-term, multi-trait experiments in ocean acidification research to better predict species vulnerability, ecosystem-level impacts, and the resilience of coastal marine communities under future climate change scenarios.</p>","PeriodicalId":49883,"journal":{"name":"Marine Ecology-An Evolutionary Perspective","volume":"46 4","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/maec.70039","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144725542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, a diverse and abundant coral community (mean cover 51.4 ± SD 14.3%) dominated by acroporids was revealed in the deep zone of the lagoon (20–25 m depth). In contrast, the shallow zone of the lagoon (2–5 m) revealed two times lower coral cover, whereas the mean proportion of coral rubble was five times greater than in the deep zone, demonstrating the general coral reef decline in the shallow zone. Of the 34 coral genera observed in the deep zone of the lagoon, 14 species from 6 genera were found to be most abundant in this coral community.

We evaluated different forms of direct-contact competition and investigated the variation among genera in their competitive abilities. We documented a total of 4151 interactions between 28 coral genera, with two-thirds of the interactions being between corals of the same genus. We found that the competitive ability of each genus was not necessarily related to the genus abundance.

While <i>Oulastrea</i> was a competitive genus on the artificial reefs, it was the opposite on natural reefs. The greater competitive capacity of genera with relatively smaller colony sizes, like <i>Oulastrea</i> and <i>Coelastrea</i>, supports the hypothesis of a trade-off between aggression and growth.

As a preliminary survey, habitat-scale (inside vs. outside lagoon habitats) sampling was attempted in two SELs during February and April.

A preliminary survey showed no clear difference in abundance among the habitats, but significantly larger juveniles were observed inside than outside the two SELs. In the seascape survey, peak juvenile abundance during the first half of the study period was concentrated in habitats other than the lagoon estuary, whereas no peak was recorded during the second half. Moreover, the lagoon estuary was significantly larger than the marine habitats, and the monthly occurrence of juveniles was continuous in the lagoon estuary but intermittent in the riverine estuary.

These changes placed the reef at level V of the BCG. The deterioration observed is strongly linked to the combined influence of ENSO-related anomalies and persistent port-related impacts, such as nutrient loading, turbidity, and invasive species transport.

The occurrence of a dry event in June/2013 was marked by low rainfall and consequently by lower river runoff, increased seasonal average salinity (19.71 ± 5.64), dissolved nutrient concentrations, and high phytoplankton biomass (chlorophyll-a). These conditions allowed a substantial increase in copepod density, particularly toward the mouth of the estuary, which was dominated by estuarine and coastal species such as <i>Pseudodiaptomus richardi</i>, <i>Oithona hebes</i>, <i>Acartia lilljeborgii</i>, <i>Acartia tonsa</i>, and <i>Paracalanus quasimodo</i>, which presented higher densities in Jun/2013 than those obtained during the normal precipitation period (June/2014). Marine species allowed a slight increase in diversity and richness, possibly caused by the increased recruitment rate from adjacent coastal waters. Results highlight that salinity, driven by precipitation, regulates copepod distribution and composition, with droughts affecting estuarine trophic dynamics in the Caeté Estuary. Future studies focused on conservation efforts must consider connectivity between resident and transitory species while addressing trophic interactions like predation and food availability.
