We sampled two tubes of <i>Ceriantheomorphe brasiliensis</i> in Florianópolis (SC), and two tubes of <i>Ceriantheopsis lineata</i> in Alcatrazes archipelago (AK), South and Southeast Brazil, respectively. The environmental DNA from the tubes was extracted, amplified, and submitted to shotgun metagenomics sequencing on the Illumina HiSeq platform, and the biodiversity analysis was run using the Kraken2 software. Our results indicate that Ceriantharia-associated microbiomes likely harbour novel microbial diversity, as roughly only 8% of metagenomic reads were classified. Microbial composition was highly similar in both locations, with the Bacteria domain predominating, particularly the phyla Pseudomonadota and Actinomycetota. Nitrososphaerota was consistently the most common archaeal phylum in all samples. The bacterial classes Betaproteobacteria and Planctomycetia, and the archaeal class Nitrososphaeria were present in all four tubes, as were the bacterial family Pseudomonodaceae and the archaeal family Nitrosopumilaceae. Roseobactereaceae dominated alphaproteobacterial families from AK tubes, while Streptomycetaceae prevailed among actinobacterial families from SC tubes. The α-diversity indicates similar values between AK and SC samples, with slight distinctions favouring SC. β-diversity results show higher similarity within the same locations (AK or SC) than between different locations, highlighting spatial influence on microbial composition. To the best of our knowledge, this study is the first to address microbial composition found in ceriantharian tubes, using shotgun metagenomics, and our findings set up the scenario for a wider comprehension of these cnidarians as key holobionts in marine ecosystems.</p></div>","PeriodicalId":8262,"journal":{"name":"Aquatic Ecology","volume":"58 4","pages":"1287 - 1300"},"PeriodicalIF":1.7,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142595360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bivalves may be used for the rehabilitation of eutrophic waters, either by being placed suspended in cages or on chains in pelagic habitats or stocked in benthic habitats. However, the effects of bivalves on the ecosystem may differ between the two habitats. A 5-week mesocosm experiment with bivalves (<i>Sinanodonta woodiana</i> Lea 1834) was conducted to test if filter-feeding bivalves suspended in pelagic habitats would improve water quality more efficiently than stocked bivalves in benthic habitats. Nutrients, suspended solids, light intensity, biomass of phytoplankton in different size fractions, and zooplankton were measured. Bivalves reduced the biomasses of total phytoplankton and nanophytoplankton and decreased the total phosphorus, total suspended solids, and organic suspended solids in both the benthic and the pelagic habitats. Bivalves also increased the light intensity and the biomass of periphyton and benthic algae. However, we found significantly higher ammonium nitrogen concentrations and higher periphyton biomass in the suspended bivalve treatment than in the benthic bivalve treatment. In both habitats, bivalve introduction reduced the abundance of cladocerans, increased the abundance of copepods but had no effect on the abundance of rotifers. The abundances of total zooplankton, cladocerans, copepods, and rotifers were similar in the treatments with suspended and benthic bivalves. These results confirm the strong effect of filter-feeding bivalves on plankton communities and their potential for the improvement of water quality whether suspended or occurring in the sediment, they indicate a potential of using filter-feeding bivalves in lake rehabilitation.</p></div>","PeriodicalId":8262,"journal":{"name":"Aquatic Ecology","volume":"59 1","pages":"53 - 66"},"PeriodicalIF":1.7,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143361757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most semiaquatic bugs (Heteroptera: Gerromorpha) live on the water surface, among hydrophytes, or on the margins of limnic habitats. These predatory insects are particularly diverse in the Neotropical Region, but they are still very poorly known in the northeastern region of Brazil, especially in the Caatinga biome. Their distribution and conservation in the area have very recently started being explored. Based on literature data and samples obtained in the northeastern Brazilian states of Alagoas and Sergipe, we present here potential geographic distribution models for 17 species of semiaquatic bugs and a potential species richness map. We designed fieldwork to reduce sampling bias by including different mesoregions of the states and areas both within and outside local protected areas (PAs). Our results reveal that gerromorphan populations exhibit distinct distribution patterns in the study area, with several species showing high habitat specificity. Furthermore, they are generally well covered by the existing PAs and higher potential richness is likely related to the environmental integrity of these areas, which might play a crucial role in locally conserving aquatic insects. Furthermore, we show that a less dense vegetal cover negatively influenced the richness found in lotic systems. This highlights the importance of maintaining and effectively managing the PAs already established in these states.</p></div>","PeriodicalId":8262,"journal":{"name":"Aquatic Ecology","volume":"59 1","pages":"21 - 37"},"PeriodicalIF":1.7,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143362184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Filter feeding influences the entire ecosystem through the transfer of energy, cycling of nutrients, and purification of water. Freshwater mussels form multispecies assemblages which may lead to food resource competition among species. This study focuses on determining which suspended food resources freshwater mussels consume and evaluates if, and to what extent, mussels in a multispecies bed are partitioning available food resources. We examined the available food resources consumed by four species of freshwater mussels, Bleufer (<i>Potamilus purpuratus</i>), Pistolgrip (<i>Tritogonia verrucose</i>), Texas Pigtoe (<i>Fusconaia askewi</i>), and Yellow Sandshell (<i>Lampsilis teres</i>), from a single mussel bed in the upper Sabine River of East Texas. Using eDNA as a measure of food availability, we found that bacteria were consumed at a higher richness and diversity than phytoplankton or zooplankton. Furthermore, we found low niche overlap of bacteria between mussel species suggesting niche partitioning may be common for freshwater mussels despite being found in a flowing river environment with potentially unlimited resources. We also found that the richness and diversity of bacteria consumed by the Yellow Sandshell is statistically higher than Pistolgrip and that these species have moderate niche overlap (0.556). These data and previous habitat data indicate that the Pistolgrip can be classified as an ecological specialist species and the Yellow Sandshell as an ecological generalist species. Overall, these results support ecological theory that mussels co-exist in the same environment because they utilize different resources.</p></div>","PeriodicalId":8262,"journal":{"name":"Aquatic Ecology","volume":"59 1","pages":"39 - 51"},"PeriodicalIF":1.7,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143362188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Artificial reef, a submerged device built by human, can pump nutrient-rich bottom water to the surface, mimicking natural upwelling to feed phytoplankton. Here we quarterly investigated the phytoplankton communities in the artificial reef zone and its adjacent water in a subtropical bay. Our results showed positive linear relationship of phytoplankton richness to productivity in the artificial reef zone.

Phytoplankton resource use efficiency (RUE) was positively correlated with richness but negatively correlated with evenness in the artificial reef zone.
