Agricultural water diversion and prolonged droughts due to climate change can also cause alterations in these ecosystems, such as modifications in flow dynamics. However, the interactions between stressors related to agricultural production and climate change are still poorly understood. Therefore, the singular and combined effects of three agricultural and climate change stressors were tested: i. nitrate enrichment (ambient/80 %/140 %/220 %), ii. fine sediment deposition (ambient and 80 % increase), and iii.- flow reduction (ambient and 66 % reduction) on the benthic macroinvertebrate community of a subtropical stream. For this purpose, we used a streamside mesocosm setup consisting of 64 experimental mesocosms. These were continuously supplied with stream water, allowing for comparable physicochemical and climatic characteristics to the adjacent stream. We investigated the individual and combined effects of the stressors on invertebrate community richness, abundance, Shannon diversity, equitability (species dominance), community composition and community size structure (size spectra). Our findings revealed that the macroinvertebrate community was affected by all three stressors, with each one influencing different structural aspects of the community. Nitrate addition had a positive effect on community evenness up to moderate enrichment levels. Sedimentation primarily decreased richness and the abundance of larger individuals, notably impacting chironomid communities that are closely tied to sediment characteristics. Flow reduction altered diversity and equitability, benefiting species such as ostracods that thrive in slow-flow environments. When combined, sedimentation and reduced flow decreased the occurrence of several rarer taxa. These findings suggest that agricultural intensification and climate change may negatively impact macroinvertebrate communities in subtropical streams through single and combined stressor mechanisms.</div></div>","PeriodicalId":34473,"journal":{"name":"Environmental Advances","volume":"20 ","pages":"Article 100630"},"PeriodicalIF":0.0,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143746643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

BDM lost 50% of its mass over first growing season while RPEM and PEM films demonstrated only 1% and 6% mass loss, respectively. In conclusion, the study provides evidence of the rapid degradation and compositional changes of BDM mulches compared to LDPE mulches, likely due to prevailing tropical climate.

We first compared two interpolated groundwater discharge models and subsequently contrasted these against stream ecology data (macrophyte and fish taxa) and surface- and groundwater quality measurements that were aggregated to derive temperature and hydrochemical (alkalinity, chloride) gradients across the hyporheic zone. Both groundwater models agreed in their prediction of discharge locations for only 52 % of monitoring sites, corroborating the need for further reconnaissance of potential discharge areas. Fish temperature preferences and ecological temperature classifications aligned reasonably with the groundwater discharge models (<55 % of sites) and air-to-stream temperature differences agreed better with groundwater discharge predicted by modeling (<em>p</em> < 0.04, R<sup>2</sup>>0.40) than stream-to-groundwater gradients (<em>p</em> < 0.1, R<sup>2</sup><0.25). Instead, hydrochemical signatures of both chloride and alkalinity in the streams were more ambiguous and displayed poor correlation with groundwater discharge maps and other monitoring parameters.
