Ecotoxicology is a science dedicated to unraveling the fate and effects of toxic substances, whether of anthropogenic or natural origin, in ecosystems. It lies at the crossroads between the understanding of fundamental mechanisms and addressing the critical societal concerns associated with environmental risk assessment. Despite being overshadowed in the realm of global change ecology, pollution ranks among the foremost causes of both present and future biodiversity loss. This HDR effectively illustrates how ecotoxicological modeling can shed light on the intricate mechanisms underlying the effects of environmental stressors across different scales of biological organization, space, and time. This knowledge is essential for predicting how toxic compounds affect individuals, populations, communities and ecosystems under various scenarios.
