The ichthyofauna inhabiting these environments benefits from the available conditions and resources, which act as environmental filters shaping species composition. This study aims to investigate the influence of landscape, local habitat, and spatial distance on the structure of fish communities in streams in the Western Amazon. Research was conducted in the Chico Mendes and Cazumbá-Iracema Extractive Reserves, located in the southwestern part of the State of Acre. A total of 25 streams were sampled, with 15 in the Chico Mendes Extractive Reserve and 10 in the Cazumbá-Iracema Extractive Reserve. To evaluate the effects of landscape variables, local habitat, and space on species richness, we used Generalized Linear Models. To assess the influence of predictor variables on species composition, we utilized Redundancy Analysis. In total, 101species were collected across the two reserves, with 49species in the Chico Mendes Extractive Reserve and 79species in the Cazumbá-Iracema Extractive Reserve. Species richness was influenced by the percentage of forest cover, which varied between reserves, while species composition was shaped by physical habitat variables. These results indicate that environmental variables at different spatial scales are crucial for the structuring of fish assemblages in Amazonian streams. Maintaining the integrity of these environments is essential for preserving habitat characteristics, which in turn support the conservation of these assemblages within and between watersheds.</p></div>","PeriodicalId":55489,"journal":{"name":"Aquatic Sciences","volume":"87 4","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145170839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Controls of littoral-benthic production can include light, nutrients, and grazers, although studies examining production across the photic zone in deep lakes are limited. This study investigates the role of nutrient limitation and inhibition from the shallow to deep (lower limit of the photic zone) littoral-benthic habitat of lakes with varying trophic states. We use a combination of nutrient-diffusing substrata (NDS), water column nutrient data, and photosynthetically active radiation (PAR) measurements. We observed that periphyton nutrient limitation and inhibition vary with depth and habitat. Differences were primarily driven by the concentration of dissolved inorganic nitrogen (DIN) and the availability of PAR. Less DIN and more PAR favored N limitation and P inhibition, whereas more DIN and less PAR favored P limitation and N inhibition. Furthermore, we found that differences in nutrient limitation in the shallow littoral-benthic habitat may be driven more by biological factors (e.g., predator density) than by variation in physical habitat heterogeneity. Our findings reveal that periphyton nutrient responses across the littoral-benthic zone for clear lakes are context-dependent. The shifting roles of nitrogen and phosphorus across depth gradients call for a more nuanced understanding of periphyton responses in lakes with extensive photic zones. Considering the importance of littoral-benthic habitat for whole lake function, additional studies exploring the role of nutrient, light, and consumers should occur across depth for clear, deep-water lakes.</p></div>","PeriodicalId":55489,"journal":{"name":"Aquatic Sciences","volume":"87 4","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145171254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

In a mesocosm experiment, we therefore studied aquatic and riparian (floodplain) invertebrate communities in response to changes in the hydrological regime as predicted by climate change and the application of the biocide <i>Bacillus thuringiensis israelensis</i> (Bti).

In addition, half of both the control and scenario floodplain mesocosms were treated with Bti at the maximum field rate applied for mosquito control. We found that the hydrological regime had contrasting effects for the aquatic and riparian communities. While the number of individuals of most aquatic invertebrates decreased in the scenario floodplain mesocosms, we found predominantly higher number of individuals of riparian arthropods. Furthermore, Bti had negative effects on some nontarget organisms, such as ground beetles and mayflies, and interacted with the hydrological regime in some cases. We conclude that the effects of both hydrological regime and Bti are taxa-dependent and that the hydrological regime revealed opposing effects between aquatic and riparian habitats.</p></div>","PeriodicalId":55489,"journal":{"name":"Aquatic Sciences","volume":"87 4","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00027-025-01214-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145169250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The major blue carbon sources in seagrass meadows since 1900 were assessed using sedimentary environmental DNA (eDNA) and chronostratigraphy. The OC stocks in the top 50 cm of the sediment cores were not significantly different between the beds of the two seagrass species and averaged 27.8 ± 7.14 Mg C ha⁻¹, which is 5 times higher than that in adjacent unvegetated sediments. The OC sequestration rate for the past 100 years was 10.3 ± 1.4 g C m⁻² year⁻¹ in <i>C. nodosa</i> sediments and 12.3 ± 5.9 g C m⁻² year⁻¹ in <i>Z. noltei</i> sediments. Sedimentary eDNA analysis revealed that the major OC source within the <i>C. nodosa</i> and <i>Z. noltei</i> sediments has been the seagrass species itself, with low contributions from allochthonous eDNA reads. Carbon sources in <i>Z. noltei</i> meadows were more diverse than those in <i>C. nodosa</i> meadows. In bare sediment, diatoms were the major carbon source. The present study demonstrates the potential of sedimentary eDNA to reveal the major sources of organic matter in blue carbon ecosystems, improving our understanding of the provenance of sedimentary OC and thus carbon cycling processes.

Understanding the intricate relationship between MPs and macrobenthos is paramount for grasping the full extent of environmental degradation within aquatic ecosystems. As MP pollution proliferates, its repercussions for macrobenthic communities including poriferans, corals, aquatic arthropods (<i>Daphnia</i>, crabs, and shrimps), mollusks (unio and mussels), and echinoderms (starfish and sea cucumbers), has become increasingly evident. This review delves into the multifaceted impacts of MPs on macrobenthos, shedding light on the ecological disruption, behavioral alterations, and potential cascading effects throughout marine and freshwater environments. From tropical reefs to freshwater rivers, sponge tissues exhibit escalating levels of MP contamination over time, reflecting the extensive bio-accumulative potential of these organisms. By studying and exploring the effects of MPs on poriferans with a comprehensive examination of existing literature, it becomes evident that MP exposure induces adverse effects including impaired feeding, increased mucus production, altered gene expression, and coral bleaching. Nanosized polystyrene (PS)-MPs delayed the developmental time and downregulated <i>Usp</i> gene expression in <i>Tigripous japonicus</i>. In mollusks, studies revealed diminished filtration rates and altered energy reserves in bivalves exposed to MPs, accompanied by oxidative damage and compromised activity of digestive enzymes. MP exposure leads to various developmental defects such as larval morphological alteration and a size-dependent impact on the larval growth and development of echinoderms. The mechanisms underlying MP-induced toxicity across various phylum are discussed, highlighting the urgent need for further research to elucidate their cumulative impacts on organismal health and fitness.</p></div>","PeriodicalId":55489,"journal":{"name":"Aquatic Sciences","volume":"87 4","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145165506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

In Ecuador, the wetlands within these páramos have been drained for cattle ranching and agriculture. One notable example is the Pugllohuma wetland, an important water reservoir for the city of Quito, which is in a recovery process. The objective of this study was to assess the influence of different types of restoration processes on the diversity and community structure of aquatic invertebrates in the Pugllohuma wetland. To evaluate this influence, three sampling campaigns were conducted in five ponds subjected to active restoration and five ponds subjected to passive restoration. During each sampling event, physicochemical parameters were measured, samples of the invertebrate communities were collected and identified to the lowest possible taxonomic level, and alpha and beta diversity analyses were performed to detect community differences associated with the restoration methods. The results showed no significant differences in alpha diversity indices between the two restoration types. However, notable differences in aquatic community composition were observed, influenced by environmental variables such as temperature, pH, and pond connectivity. In ponds with passive restoration, species turnover had a stronger influence on beta diversity, whereas in ponds with active restoration, differences in species abundance were more significant. This study highlights the importance of evaluating aquatic community structures when assessing the effectiveness of restoration processes in wetlands of the Andean páramos, providing valuable insights for their management and conservation. Restoration efforts often result in heterogeneous landscapes, making it essential to understand how biodiversity responds to this spatial variability.
