They can be found across a range of habitats varying from perturbed and pristine coral reefs to harbours and marine lakes and from the deep sea to shallow waters. They can be difficult to distinguish in the field and have presented some problems with taxonomists lumping and splitting species due to the difficulty in defining clear species boundaries. In the present study, we sampled golf ball sponges from Indo-Pacific and Caribbean locations and used 16S gene amplicon sequencing to study their prokaryotic communities. We show that golf ball sponges harbour a wide variety of prokaryotic communities. Among the most prevalent operational taxonomic units (OTUs), several belonged to a range of taxa, including the bacterial AqS1 and EC94 groups, which have been associated with genes known to facilitate interactions between hosts and microbes. Certain host taxa were enriched with OTUs classified to the SAR202 clade of Chloroflexi. Our findings show that prokaryotic dissimilarity varied as a function of space (geographical distance) and host dissimilitude. The importance of space and host dissimilitude, however, varied depending on the data transformation with host dissimilitude a more important predictor of untransformed data whereas space was a more important predictor of log-transformed data. Given that log-transformation downscales the influence of abundant taxa, we interpret these results by the tendency of closely related host organisms to host similar sets of abundant symbiotic microorganisms; distantly sampled specimens, in contrast, tend to harbour less abundant prokaryotic microorganisms found in the surrounding environment (e.g., seawater or sediment).</p>","PeriodicalId":49883,"journal":{"name":"Marine Ecology-An Evolutionary Perspective","volume":"45 5","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/maec.12815","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141530177","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}

Due to their incapability to recover effectively naturally, assisted restoration is used. This study aimed to test textile fabrics from natural derivatives to serve as carrier substrates for seagrass transplantation. The use of biotextile fabrics should enable seagrasses to better withstand hydrodynamic forces, especially in high-energy areas and during autumn and winter storms in the initial phase of restoration, thereby increasing restoration success. Here, the biodegradation behavior of three natural textiles was assessed in different configurations. Coir, sisal, and jute meshes were fixed on the top and bottom of a coir nonwoven mat, forming a so-called “sandwich structure.” Specimens were buried in the Ria Formosa Lagoon, Portugal, and retrieved weekly within the first months of burial and subsequently monthly over a total period of 3 months. Weight, tensile strength, and oxygen consumption rate were used as descriptors for biodegradation and tested after each retrieval. The results obtained in this study were discussed in the context of the application of the tested materials on <i>Zostera marina</i> transplants. Due to experimental errors, these results are solely used for discussion purposes in a conservative manner. Based on the three descriptors, coir mesh was the least degraded by the end of the experiment. Yet, it is vital to analyze the microbiome in a study site to understand the biodegradation process and based on that select a textile material. Coir fibers appear to be a good choice in highly biologically active areas to prolong the degradation process, whereas in areas with less activity sisal could be sufficient and even beneficial through the release of compounds that foster vegetations induced by degradation.</p>","PeriodicalId":49883,"journal":{"name":"Marine Ecology-An Evolutionary Perspective","volume":"45 5","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142540896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These particles, which come from a variety of sources such as the decomposition of bigger plastic objects and the microfibres that are shed from textiles, are extremely dangerous to ecosystems and marine life. This study provides a detailed analysis of the global issue of microplastic pollution, including its origins, effects on marine ecosystems, current mitigation techniques, and future research prospects. The review divides microplastics into main and secondary categories, detailing their sources ranging from plastic pellets and microbeads to the breakdown of bigger plastic items such as bottles and bags. It emphasises the negative impacts of microplastics on marine species, aquaculture, and human health, such as gastrointestinal obstructions, toxic chemical accumulation, and cancer risk to human health. The review also examines the economic and environmental consequences of marine plastic pollution, highlighting the importance of effective policies and remedies. Furthermore, the article covers several researches on microplastic contamination in coastal sediments, seafood, and aquatic creatures from diverse locales. It addresses methods for collecting, extracting, and analysing microplastics, as well as advances in machine learning and spectroscopic techniques for precise identification and measurement. Furthermore, the study summarises the research on the ecological hazards presented by microplastics, such as their movement patterns, accumulation in marine ecosystems, and possible long-term effects. The study also examines the problems and limitations in existing research, such as the need for consistent data collection processes, a better knowledge of microplastic behaviour in various settings, and the development of novel mitigating solutions. Overall, this study gives an in-depth summary of the current state of knowledge on microplastic contamination, emphasising the critical need for more research, legislative interventions, and public awareness campaigns to ameliorate its negative impacts on marine ecosystems and human health.</p>","PeriodicalId":49883,"journal":{"name":"Marine Ecology-An Evolutionary Perspective","volume":"45 5","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142540899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
