Climate change and additional anthropogenic pressures induce a wide range of environmental changes in aquatic environments, such as gradual warming, ocean acidification, amplified extreme events, or altered light- and nutrient regimes. However, community and ecosystem level responses to these changes remain unclear as highly controlled laboratory experiments cannot reflect the full complexity of natural systems. Mesocosm experiments are an important tool to fill this knowledge gap by providing a near-natural setting for studying higher system complexity, species interactions, and by offering a wide range of possibilities to manipulate environmental conditions and to test mitigation measures. In this session, we welcome submissions on mesocosm experiments examining single or multiple stressor impacts on different aquatic systems. Studies can focus on the effects on single organisms, populations, or communities (e.g., phytoplankton, zooplankton, benthos, fish), their ecosystem functions, resistance, resilience and recovery as well as eco-evolutionary responses. We aim to include studies across a wide range of aquatic habitats (e.g., fully marine, intertidal, lakes, rivers). Overall, the session aims to provide a comprehensive insight into the possibilities and limitations of mesocosm research for assessing the impacts of global change related stressors on aquatic systems. We hope that this session will fuel the discussion on the status quo in mesocosm research and inspire future collaborations. Join us in exploring the diversity of mesocosm-based experiments used across aquatic systems!

Benthic ecosystems, comprising the diverse communities of organisms inhabiting the ocean floor, play a pivotal role in maintaining ecological balance and sustaining the health of marine environments. Focusing on these vulnerable ecosystems, we examine the multifaceted threats faced by benthic organisms and the subsequent repercussions for ecosystem resilience. Benthic organisms are exposed to a myriad of stressors such as rising sea temperatures, ocean acidification, and alterations in nutrient cycling. Benthic macrofauna plays a key role in organic matter processing and benthic-pelagic carbon cycling directly through their metabolism and indirectly through bioturbation. The on-going changes in the ocean disrupt symbiotic relationships, hamper reproductive success, and influence biodiversity elements and physiological traits of benthic communities. The environmental changes could therefore lead to a different functional role of benthic flora and fauna in key ecosystem processes. Linkages between benthic ecology and ecosystem health including local stressors and global climatic factors, need to be recognised for effective conservation and management strategies of benthic ecosystems in the face of an uncertain future. If you are studying the benthic ecosystems (no matter if fauna, flora, sediment or water) in our changing oceans, you are very welcome in our session!

Marine coastal environments are considered as the most diverse places on Earth. They are subjected to strong dynamic interactions both with the pelagic and the terrestrial environment, and thus more vulnerable to global change and anthropogenic pressure. There is a strong need to understand current ecological processes at different biological scales in the field (individual to ecosystems) and how climate change could modify the physiology, interactions and ecosystem structure. We are looking for researchers working on coastal ecology and/or climate change effect on coastal ecology, using different tools at any biological and taxonomic level. We would like to bring different expertise together to highlight the potential of using complementary approaches for coastal ecology research.

Recognising the pivotal role that coastlines, seas, and the ocean play in human existence underscore the critical need to prioritise marine environmental protection. In response to this necessity, major international organisations such as the International Maritime Organization (IMO) have taken extensive and targeted measures to protect marine life. The current international legal regime in the field of marine environmental protection is governed by a relatively advanced treaty and customary legal system. Advancements in marine environmental law even leveraged developments in other fields of environmental law. Despite international endeavours to lawfully protect the marine environment and biodiversity against pollution, overexploitation, or the effects of climate change, the main question arises: how does international environmental law effectively protect and preserve the marine environment? Join our session to scrutinise critical aspects of marine environmental protection, exploring the international legal order consisting of instruments and organisational initiatives contributing to this paramount cause.

Marine plastic pollution is a considerable challenge faced across the globe, irrespective of locations and climates. Considerable sources of marine plastic pollution include several industries, such as fisheries and aquaculture. Both fishing and aquaculture industries and other maritime operations are highly reliant on use of plastic materials in various equipment which can result in production in marine plastic litter. Such plastic materials often used by fisheries and aquaculture industries could remain in the ocean for a long time and create macro- and microplastic pollution with associated negative effects on the marine environment. Furthermore, in fisheries, one of the large challenges is pollution caused by abandoned, lost or otherwise discarded fishing gears (ALDFG). Such gear can result in prolonged continuous capture and mortality of marine animals, so-called “ghost fishing” due to use of persistent plastic material in fishing gear construction. This session aims to bring together ideas and previous and ongoing research on marine plastic pollution resulting from fisheries and aquaculture industries or marine operations as well including, but not limited to, pollution rates, ghost fishing, impact of plastic pollution on the marine environment. The session could include a broad range of topics from fishing gear technology related fields up to toxicity caused by microplastics that are resulted from fisheries and aquaculture.

Sclerochronology is known as a discipline that provides baseline data for a variety of life history, ecology, and management studies. Nowadays it’s hard to imagine a comprehensive study on species biology that does not provide a piece of information on its maximum age or growth rates. In paleoclimatic studies, it allows the reconstruction of past environmental conditions. Many stock assessment protocols presume collecting data on the age composition of the stock units. But sclerochronology is much more than a convenient tool! The discipline provides a great variety of insights per se. Analysis of recording or hard structures trace element or isotope composition, modelling of morphological responses in these structures to different environments, and global variation in growth rates of animals, all are just the tip of the iceberg of the variety of sclerochronological studies. Moreover, the field of research has been rapidly developing in the past years, and the dream technologies of the past, like 3D image analysis or modelling of hydrodynamic properties of molluscan shells, become true and even routine. In our eyes, this theme session provides a platform for a broad discussion on the recent advances in all the fields of sclerochronology, from studies on micro- and macrostructure of recording structures to the practical application of the age and growth data in stock assessment. Are there fields of sclerochronological research we didn’t mention here or ones we even can’t imagine? We are excited to hear about it! At the “Sclerochronology – providing insights for life history, ecology, and management studies” theme session we warmly welcome paleontologists, biologists, ecologists, fishery scientists, and everyone who shares our passion for sclerochronological research.
