These stressors can individually affect the aerobic capacity and stress tolerance of fish. In combination, they may interact in unexpected ways where exposure to one stressor may heighten or reduce the resilience to another stressor and their interactive effects may not be uniform across species. Here, we examined how nitrate pollution under a warming scenario affects the aerobic scope (AS), and the hypoxia and heat stress susceptibility of a generally tolerant fish species, common carp <em>Cyprinus carpio.</em> We used a 3 × 2 factorial design, where fish were exposed to one of three ecologically relevant levels of nitrate (0, 50, or 200 mg NO<sub>3</sub><sup>-</sup> L<sup>−1</sup><span>) and one of two temperatures (18 °C or 26 °C) for 5 weeks. Warm <a href=\"/topics/earth-and-planetary-sciences/acclimatization\" title=\"Learn more about acclimation from ScienceDirect's AI-generated Topic Pages\" class=\"topic-link\">acclimation</a> increased the AS by 11% due to the maintained standard metabolic rate and increased maximum metabolic rate at higher temperature, and the AS improvement seemed greater at higher nitrate concentration. Warm-acclimated fish exposed to 200 mg NO</span><sub>3</sub><sup>-</sup> L<sup>−1</sup> were less susceptible to acute hypoxia, and fish acclimated at higher temperature exhibited improved heat tolerance (critical thermal maxima, CTMax) by 5 °C. This cross-tolerance can be attributed to the hematological results including maintained haemoglobin and increased haematocrit levels that may have compensated for the initial surge in methaemoglobin at higher nitrate exposure.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Better together: cross-tolerance induced by warm acclimation and nitrate exposure improved the aerobic capacity and stress tolerance of common carp <i>Cyprinus carpio</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-10 01:32:43.588635","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Climate change; Eutrophication; Hypoxia; Aerobic capacity; Cross-tolerance; Multiple stressors","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2022-11-30","DateCreate":"2022-06-28","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000696957100006","VABBcode":null,"OpenAcc":1,"DOI":"10.1016/j.ecoenv.2021.112777"},"refs":null,"anarec":{"AnaID":353193,"PubliDate":2021,"Pagination":"112777","XtraPublOfAnaID":null,"ISBN":null,"Volume":"225","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42636,"SerRR":"Ecotoxicology and Environmental Safety.
