Water hyacinth (Eichhornia crassipes) is recognized as one of the world's top 100 weed species and among the ten worst aquatic weeds. This study examines the impact of extracts from this non-native invasive plant on the survival, growth, and metamorphosis of Bufotes sitibundus larvae, a species of anuran amphibian. Due to the presence of phenolic compounds and heavy metals, invasive plants can significantly affect anuran development, yet these threats remain largely unstudied in amphibians. We observed increased mortality in larvae exposed to water hyacinth extracts, which we attribute to reduced oxygen availability linked to high concentrations of phenolic compounds, such as (E)-23-ethylcholesta-5,22-dien-3.beta.-ol and 3-Hydroxyspirost-8-en-11-one, as well as the terpenoid gibberellin A3. These phenolic compounds may impair gill function, contributing to decreased survival rates. Additionally, the presence of heavy metals in the extracts adversely impacts survival, growth, body length, and metamorphosis. The invasive water hyacinth can lead to significant alterations in pond ecosystems, producing both direct and indirect effects on amphibian survival. Our findings offer crucial insights into the effects of water hyacinth extracts on amphibians, encompassing egg development, growth, mortality, and metamorphosis, potentially impacting the biology and ecology of Bufotes sitibundus during the critical developmental stages.</p>","PeriodicalId":11497,"journal":{"name":"Ecotoxicology","volume":" ","pages":"1406-1418"},"PeriodicalIF":2.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144552601","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}

This study presents an integrated assessment of water quality in the Lonqueador River in southwestern Paraná, Brazil, combining physicochemical analyses and ecotoxicological assays using multiple bioindicators. Water samples were collected at seven sites (P1 to P7) distributed along the river, from its source in the municipality of Marmeleiro to its confluence with the Marrecas River in the urban area of Francisco Beltrão. P1 and P2 represent predominantly agricultural and forested areas, while P3 reflects a transitional zone characterized by expanding urban development, industrial activity, and a major road junction. P4 covers a peri-urban area, and P5, P6, and P7 lie in fully urbanized zones. Sampling campaigns were conducted during high-flow (H) and low-flow (L) periods. The water samples showed inhibition growth and development of Aspergillus nidulans (P1 to P7, H and L, except P4H and P6H), mortality/immobility of Artemia salina (P6L, P7L, P3H), escape of Eisenia fetida worms (P7L), cytotoxicity to Huh7.5 cells (P7L), emergence of nuclear alterations (P1H, P2 H and L, P3H, P5 H and L, P7L) and micronucleus (P1H, P2H, P3H, P4H, P5H, P7H) in Lithobates catesbeianus, and cytotoxic (P1H, P2H, P5H, P7H) and mutagenic (P5L) effect on Allium cepa. Heavy metals, particularly manganese, were detected in higher concentrations during high flow, whereas hormones E1, E2, and EE2 were more frequent during low flow. These findings highlight the importance of integrated approaches for monitoring and managing water quality in watersheds.</p>","PeriodicalId":11497,"journal":{"name":"Ecotoxicology","volume":" ","pages":"1419-1446"},"PeriodicalIF":2.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144559519","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}
