摘要：SummaryGrowing anthropogenic activities are significantly influencing the environment and especially aquatic ecosystems. Therefore, there is an increasing demand to develop techniques for monitoring and assessing freshwater habitat changes so that interventions can prevent irrevocable damage. We explore an approach for screening the temperature-induced stress experienced by aquatic organisms owing to environmental variations. Luminescent spectra of upconversion [Y2O3: Yb, Er] particles embedded withinCaridina multidentatashrimps are measured, while ambient temperature gradient is inducing stress conditions. The inverse linear dependence of the logarithmic ratio of the luminescence intensity provides an effective means for temperature evaluation inside aquatic speciesin vivo. The measured luminescence shows high photostability on the background of the complete absence of biotissues’ autofluorescence, as well as no obscuration of the luminescence signal from upconversion particles. Current approach of hybrid sensing has a great potential for monitoring variations in aquatic ecosystems driven by climate changes and pollution.Graphical abstractDisplay OmittedHighlights•Luminescence spectra induced by upconversion particles are embedded into aquatic animals•Real-time quantitative assessment of temperature inside aquatic speciesin vivo•Evaluation of stress handled by water organisms owing to environmental variations•Hybrid sensing approach for monitoring environmental variations driven by climate changeEnvironmental science; Aquatic science; Zoology; Physiology
