{"title":"Food-Web Impacts of Controlling Macrophytes and Algal Blooms Using Herbicides and Algicides in Invaded Aquatic Systems","authors":"Aaron B. Stoler,&nbsp;Rick A. Relyea","doi":"10.1111/fwb.70075","DOIUrl":"https://doi.org/10.1111/fwb.70075","url":null,"abstract":"<div>\u0000 \u0000 <p>\u0000 \u0000 </p><ol>\u0000 \u0000 \u0000 <li>Given the expansion of aquatic plants (i.e., macrophytes) that can occur with eutrophication, lakes and ponds are often managed with herbicides to kill large areas of undesired plants. In doing so, the dead plants decompose and release large amounts of nutrients that can facilitate major algal blooms, which are subsequently managed by applying algicides. These rapid shifts in community structure might also encourage other shifts, such as the proliferation of invasive species. More understanding is needed about how herbicides and algicides affect entire food webs, including food webs containing invasive species.</li>\u0000 \u0000 \u0000 <li>We employed outdoor mesocosm communities to explore the community-wide effects of a common herbicide (fluridone) and an algicide (copper sulphate; CuSO₄). Communities included algae, zooplankton, Eurasian milfoil (<i>Myriophyllum spicatum</i>) and two native snails (<i>Physa acuta</i> and <i>Helisoma trivolvis</i>). We further manipulated the presence of the invasive Chinese mystery snail (<i>Cipangopaludina chinensis</i>) to examine how the same chemicals might alter its ability to invade a community.</li>\u0000 \u0000 \u0000 <li>Surprisingly, we discovered that the herbicide caused a 40% reduction in phytoplankton and a decline in copepods, likely as an indirect effect. Adding CuSO₄ caused a 60% reduction in phytoplankton but no reduction in periphyton, while also causing an increase in cladocerans and declines in copepods and the two native snail species. In contrast, the invasive Chinese mystery snail was unaffected by the algicide, while it drove down the abundance of periphyton and one of the native snails.</li>\u0000 \u0000 \u0000 <li>Collectively, these results highlight the importance of examining multiple human impacts—alone and in combination—to more effectively assess the planned and inadvertent effects of human activities on aquatic ecosystems.</li>\u0000 </ol>\u0000 \u0000 </div>","PeriodicalId":12365,"journal":{"name":"Freshwater Biology","volume":"70 7","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144615360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Resource quality was assessed by omega-3 (ω3) long-chain polyunsaturated fatty acids (LC-PUFA), while resource quantity was evaluated based on biomass.

However, this increase in quantity was accompanied by a notable reduction in ω3 LC-PUFA in primary producers, resulting in a distinct FA stock pyramid with a narrowed base and middle. This pattern suggests that despite high phytoplankton biomass, poor food quality created a resource quality bottleneck that constrained the transfer of essential fatty acids.</li>\u0000 \u0000 \u0000 <li>This reduction in resource quality simplified the transfer pathways of ω3 LC-PUFA to piscivorous fish, limiting their dietary options and weakening trophic connections.
