Abstract
Urbanization and inadequate wastewater treatment contaminate freshwater ecosystems with complex chemicals, which, along with climate change, threaten freshwater insects. To assess these impacts, we conducted a 21-day microcosm experiment simulating a simplified freshwater food web containing moss and larvae of two caddisfly species, Drusus croaticus and Allogamus uncatus. The experiment included control (C), increased temperature (T2 = C + 4 °C), emerging contaminants mixture (EC), and multiple stressor treatment (MS = EC + T2). We analysed caddisfly mortality, body weight, locomotor activity (distance moved), and compared species-specific effect of selected stressors. ECs exposure increased average body weight in both species with contrasting effects on locomotor activity, increasing larval average distance moved in D. croaticus but reducing it in A. uncatus. T2 treatment caused the highest mortality for D. croaticus larvae, while the mortality of A. uncatus larvae was similar in all treatments. MS treatment significantly impacted D. croaticus larvae behaviour, leading to reduced larval average distance moved compared to other treatments, highlighting the complexity of multiple stressor interactions. The observed interspecies variability emphasizes the importance of considering species-specific characteristics in ecological risk assessments. These findings offer insights into how multiple stressors may impact caddisfly populations, crucial members of aquatic ecosystems.
Abstract (english)
Urbanizacija i neadekvatna obrada otpadnih voda onečišćuju slatkovodne ekosustave smjesama onečišćivača, koji s klimatskim promjenama ugrožavaju slatkovodne kukce. U svrhu procjene tih utjecaja, proveli smo 21-dnevni eksperiment stimulirajući pojednostavljenu slatkovodnu hranidbenu mrežu s mahovinom i ličinkama dviju vrsta tulara, Drusus croaticus i Allogamus uncatus. Eksperiment je uključivao kontrolnu skupinu (C), tretman s povišenom temperaturom (T2 = C + 4 °C), smjesom onečišćivača (EC) te višestrukim stresorima (MS = EC + T2). Analizirali smo smrtnost, srednju tjelesnu težinu, lokomotornu aktivnost (srednja prijeđena udaljenost) tulara te usporedili učinak odabranih stresora specifično na svaku vrstu. Izloženost smjesi onečišćivača povećala je prosječnu tjelesnu težinu u obje vrste, s kontrastnim učincima na lokomotornu aktivnost, povećavajući prosječnu prijeđenu udaljenost ličinki D. croaticus te je smanjujući za ličinke A. uncatus. Povišena temperatura (T2) uzrokovala je najveću smrtnost ličinki D. croaticus, dok je smrtnost ličinki A. uncatus bila slična u svim tretmanima. Tretman višestrukim stresorima značajno je utjecao na ponašanje ličinki D. croaticus, smanjujući prosječnu prijeđenu udaljenost u usporedbi s kontrolnom skupinom i drugim tretmanima, naglašavajući složenost interakcija višestrukih stresora. Uočena varijabilnost među vrstama naglašava važnost razmatranja karakteristika specifičnih za pojedinu vrstu. Naša otkrića pružaju uvid u utjecaj višestrukih stresora na populacije tulara, ključne članove vodenih ekosustava.
