Plastic pollution is ubiquitous in marine environments globally and presents an environmental challenge that extends throughout food webs, threatening organism and ecosystem health. Microplastic debris is of particular concern since ingestion of synthetic particles and fibers have been documented in a variety of marine species, including the smallest of zooplankton to the largest marine mammals in the sea.
Given that organisms inhabiting coastal ecosystems are subjected to many stressors, including variations in temperature and salinity related to global climate change and chemicals present in run-off or associated with plastics themselves; we must also consider that plastic debris represents one of a myriad of anthropogenic threats. Understanding the interactions that occur within (e.g. stress response) and between organisms (e.g. trophic transfer) at different levels of biological organization in an environmentally relevant context is critical to accurately measure and predict the impacts of plastic pollution, to assess risk, and to project species resilience in the Anthropocene.
Presentations addressing these challenges in marine and estuarine organisms across taxa are welcome. The session will highlight both field and laboratory research investigating microplastic exposure in the field or laboratory and may also be considered in the context of conditions induced by global climate change, such as ocean acidification, hypoxia, increased temperature, varied salinity, or species interactions. Studies can address responses at the molecular (e.g. gene expression), organism (e.g. reproduction), or population scale.
