Abstract
Antropogeni izvori svjetla i njihovi učinci na vodozemce predstavljaju rastući globalni problem, osobito zbog umjetnog svjetla noću (ALAN). Ovaj diplomski rad istražuje utjecaj tople LED svjetlosti na razvoj punoglavaca vrste Bufotes viridis (Laurenti). Punoglavci su bili izloženi kontrolnim uvjetima (12 h imitacije danjeg svjetla i 12 h mraka) te tretmanu (12 h imitacije danjeg svjetla i 12 h tople LED svjetlosti). Nakon dvotjednog izlaganja, uspoređene su njihove mase, duljine glava i repova te razvojni stadiji. Analizirani su i biomarkeri acetilkolinesteraza (AChE) i glutation S-transferaza (GST), kao i energetsko stanje kroz koncentraciju ugljikohidrata, lipida i proteina. Kod morfometrijskih parametara i biomarkera nije uočena značajna razlika, no uočena je kod energetskog stanja u koncentraciji proteina. Rezultati pokazuju potencijalne negativne učinke ALAN-a na razvoj vodozemaca, ističući važnost regulacije umjetnog osvjetljenja u njihovim staništima. Naši nalazi sugeriraju da topla LED svjetlost može značajno utjecati na fiziološke i biokemijske parametre punoglavaca, što može dovesti do dalekosežnih posljedica po njihove populacije i ekosustave. Potrebna su daljnja istraživanja i razvoj strategija za ublažavanje negativnih učinaka ALAN-a na vodozemce.
Abstract (english)
Anthropogenic sources of light and their effects on amphibians represent a growing global problem, particularly due to artificial light at night (ALAN). This thesis investigates the impact of warm LED light on the development of tadpoles of the species Bufotes viridis (Laurenti). Tadpoles were exposed to control conditions (12 hours of simulated daylight and 12 hours of darkness) and treatment conditions (12 hours of simulated daylight and 12 hours of warm LED light). After two weeks of exposure, their masses, head and tail lengths, and developmental stages were compared. Biomarkers acetylcholinesterase (AChE) and glutathione S-transferase (GST) were analyzed, as well as the energy status of the tadpoles through the total concentration of carbohydrates, lipids, and proteins. No significant differences were observed in morphometric parameters and biomarkers, but differences were noted in the energy status, specifically in protein concentration. The results indicate potential negative effects of ALAN on amphibian development, highlighting the importance of regulating artificial lighting in their habitats. Our findings suggest that exposure to warm LED light can significantly impact the physiological and biochemical parameters of tadpoles, potentially leading to far-reaching consequences for their populations and ecosystems. Further research and the development of strategies to mitigate the negative effects of ALAN on amphibians are necessary.
