Along the Potiguar Basin continental shelf, carbonate sediments, produced by calcareous algae (rhodoliths) and corals, dominate. The ecology of rhodolith beds has been the subject of relatively few studies despite this ecosystem being under strong pressure due to its large economic potential, especially in poorly known tropical areas, and because of global climate change that will likely have a profound impact on crustose coralline species. In the Potiguar Basin, oil spill hazards should also be considered as potential sources of stress due to its history of oil and gas exploration in both onshore and offshore areas. This study focuses on the spatial and temporal patterns of meiofauna communities and their relationship to natural variables. Four campaigns were conducted. Three replicates at four isobaths (5, 10, 20 and 50 m) were sampled, in which 20 stations, each at a distance of 20 km, were positioned, totaling five transects (T1–T5). For each of the Nematoda, Copepoda, and Tardigrada groups, which together accounted for more than 88% of total meiofauna abundance during each campaign, up to 100 individuals per replicate, when available, were identified to the lowest taxonomic level. Three hundred and twenty one lower taxa (species and genera) were identified, with an overall average density of almost 700 ind.cm<sup>−2</sup>. The data indicate that the Potiguar Basin benthos has one of the most diverse meiofauna communities ever sampled, with densities falling within the ranges of similar continental shelf environments. Considering spatial variation, a large part of the meiofauna community variability was clearly related to the presence of the Açu incised valley. Despite the importance of spatial factors, which would suggest sediment parameters as the most important, our analysis indicated that ecological interactions may have the same importance in this eco-engineered system. Temporal variation was particularly evident in the density trend. We hypothesize that the much lower meiofauna densities observed during the 2014 campaigns were the result of a very strong seawater warming event during 2010, associated with the ENSO of 2009–2010, and a subsequent strong reduction in precipitation over several years, due to an anomalously northward position of the ITCZ. This hypothesis predicts that as climate change continues, there will be widespread modifications in the structure and functioning of meiofauna communities in rhodolith beds.</p>","PeriodicalId":49883,"journal":{"name":"Marine Ecology-An Evolutionary Perspective","volume":"46 2","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/maec.70019","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143879858","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}

We surveyed fish populations in a tropical bay, covering a spatial gradient from the outer zone with favorable marine conditions to the inner zone affected by human activities. The tested hypothesis is that natural environmental gradients (e.g., temperature, salinity, turbidity) and anthropogenic influences (e.g., pollution, organic enrichment) affect fish communities and that environmental filters reduce taxonomic and functional diversity in more impacted zones. Species richness increased, while fish abundance and biomass decreased from the inner to the outer zone. Only functional divergence changed spatially, being higher in the outer zone. This suggests changes in species but the maintenance of most functions. Fourteen functional groups were identified based on locomotion and food acquisition traits. Higher taxonomic diversity and functional divergence in the outer zone likely stem from greater resource utilization differentiation and more favorable environmental conditions near the sea, fostering species with distinct functional attributes. Conversely, the inner zone, burdened by high organic and pollutant loads, favors species highly tolerant of harsh environmental conditions, such as marine catfishes. Fish communities exhibited spatial changes due to environmental gradients and anthropogenic influences. Environmental filters altered taxonomic indices, while functional indices remained stable, except for functional divergence, which was lower in the most impacted area, partially confirming our hypothesis. These findings advance our understanding of environmental influences on species distribution along spatial gradients in coastal systems, proving to be a promising and increasingly utilized tool for ecological assessment.</p>","PeriodicalId":49883,"journal":{"name":"Marine Ecology-An Evolutionary Perspective","volume":"46 2","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/maec.70016","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143840524","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}

The low selectivity of this gear, coupled with its mode of operation, results in the bycatch of juveniles of commercially important fish species and other non-target organisms, which are consequently discarded. This study investigates the macrofaunal constituents of beach seine bycatch discarded along the coast of Ghana and the potential implications for the country's fisheries. Discards from two beach seine nets were collected and examined monthly from Dzelukofe, Bortianor, and Cape Coast over a period of six months, from August to October 2022 for the wet season and December 2022 to February 2023 for the dry season. In total, 71 species (15,708 individuals) were recorded at Dzelukofe, 65 species (5158 individuals) at Duakor, and 62 species (8030 individuals) at Bortianor. Eighty (80) species made up of 20,545 individuals were recorded during the dry season, while 75 species comprising 8,351 individuals were recorded during the wet season. Bivalves accounted for 41.1% of the macrofauna encountered, followed by cephalopods (35.7%) and malacostracans (21.9%). The remaining macrofauna together accounted for &lt; 3%.

This trend could be true for other commercially important fish species found in the beach seine discards.

The composition of faunal communities associated with sunken wood is influenced by several factors, including the physical properties of the wood itself, such as species, mass, and surface area, as well as environmental conditions like water depth, geographic location, and the stage of ecological succession. These factors interact to shape the biodiversity and ecological processes within wood falls, making them temporally and spatially finite habitats. Their distinct boundaries and lifespans are tightly linked to the rate of wood degradation, primarily driven by specialized wood-boring organisms. Despite their ecological significance, most knowledge about wood-fall ecosystems comes from experimental studies rather than from observations of naturally occurring wood falls. This has left significant gaps in our understanding of the natural variability and ecological roles of these systems in the deep sea. The scarcity of natural wood-fall records poses challenges for fully grasping their contribution to deep-sea biodiversity, carbon cycling, and biogeography. In this review, we synthesize the current state of knowledge on wood-fall ecosystems. We also explore the potential applications of wood-fall research in broader ecological, industrial, and environmental contexts. Wood falls offer valuable insights into deep-sea ecosystem functioning, biodiversity maintenance, and species evolution.</p>\u0000 </div>","PeriodicalId":49883,"journal":{"name":"Marine Ecology-An Evolutionary Perspective","volume":"46 2","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143595427","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}
