Thresholds and interactive effects of BPA-gradient and temperature on life history traits of Daphnia magna

Environmental Pollution, Journal Year: 2024, Volume and Issue: 355, P. 124186 - 124186

Bisphenol A (BPA), a synthetic organic compound widely used in the production of plastics, is recognized as an emerging contaminant because its toxicity and potential risks associated with bioaccumulation organisms. Despite environmental hazards, there lack studies examining BPA mechanisms impact on various trophic levels, even fewer exploring whether global stressors such temperature can affect Our aim was to assess combined varying regimes life-history traits Daphnia magna. results revealed significant growth, reproduction, accumulated moulting D. magna, adverse effects primarily assimilation algae rather than present medium, pointing transfer mechanism. The interactive effect between demonstrated slight stimulatory low level magna growth rate under warming constant conditions, but inhibitory fluctuating temperatures. Additionally, threshold identified, below which became temperature-dependent. This study emphasizes crucial role considering predicting how toxins may within aquatic food webs.

Abstract Environmental contamination of bisphenol A (BPA) is a widespread and multifaceted issue with vast ecological, social economic consequences. Thus, understanding how local environmental conditions, such as temperature, interact BPA to affect populations community dynamics remain important areas research. Here, we conduct laboratory experiments aimed at gradients both temperature concentration influence freshwater phytoplankton population growth structure. We exposed assemblages comprised three common species green algae (Chlorella vulgaris, Ankistrodesmus braunii Scenedesmus quadricauda) well isolates each individual concentrations (0, 2, 13 mg/L BPA) temperatures (18, 23, 27°C) monitoring structure (via biovolume). observed antagonistic interactions between warmer temperatures, that when decreased (observed A. braunii), high elevated these warm temperatures; however, increased (C. S. quadricauda), diminished gains. Although exposure inhibited the most C. vulgaris populations, was not reduced in or quadricauda 2 BPA. Phytoplankton assemblage evenness (Pielou index) consistently lowest under 27°C. Community composition similar cultured 0 18 23°C but These results indicate can mediate consequences for rates diminish potential gains rate warm-adapted temperatures.

How Does Warming Affect Bisphenol a Toxicity on Cryptomonas Sp. And its Herbivorous Consumer Daphnia Magna?

Published: Jan. 1, 2024

The increasing production of plastics worldwide has resulted in a massive deposition these materials aquatic ecosystems, triggering the subsequent release chemical compounds as plastic degrades. Among derivatives, bisphenol A (BPA) represents global issue due to its role an endocrine disruptor and presence large portion planet's ecosystems. Furthermore, toxicity BPA on organisms can be modulated by change stressors such temperature, which plays essential metabolism organisms, including degradation accumulation toxic compounds. In this study, we aimed understand how temperature modulate effect phytoplankton species (Cryptomonas sp.) transferred herbivorous consumer (Daphnia magna). To do this, first determined lowest observed concentration (LOEC) growth Cryptomonas sp., subsequently, increase (+5ºC) could modify physiology, phytoplankton. Finally, investigated rate D. magna through food. Our results show that LOEC value was 5 mg L-1 for negatively affecting photosynthetic yield photosystem II, net primary production, respiration, growth. This brought forward when higher. Additionally, also decreased fed sp. grown high temperature. indicate bring effects located at base food web higher levels, leading significant changes population dynamics communities
