1. Coastal Wetland Ecosystems under Climatic Change

Conveners: Catherine Lovelock (University of Queensland, Australia), ken Krauss (U.S. Geological Survey, USA)
Coordinator: Luzhen Chen (Xiamen University, China)

This session will present research on the challenges of climate change investigations for coastal wetland ecosystems, including efforts to understand the mechanisms and processes of climate change influences on coastal wetland ecosystem adaptation. We will highlight what we have accomplished in climate change research, what we have learned about thresholds of response, and how humans have influenced the ability of coastal wetland ecosystems to respond to climate change as they would normally. The session is proposed for two half days and includes opening remarks and a plenary address, followed by eight speakers covering research from multiple coastal wetland types. These talks will highlight important advancements made by individual and collaborative coastal wetland research programs, including those of Chinese scientists who have contributed greatly to advancing coastal wetland science globally. The plenary speaker (mid-career scientist) will conduct a synthesis of the current research. All subsequent presentations will be split between mechanism and process topics. Speakers will have expertise in areas such as tidal saltmarsh and freshwater wetlands, seagrasses and mangrove ecosystems, carbon flux analysis, carbon burial rates, biodiversity conservation, relationships with soil and hydrological processes, and challenges facing ecological restoration projects in a changing climate.

2. Coastal Alien species, Invasion, and its Impacts on Coastal Ecosystem Services

Conveners: James Byers (University of Georgia, USA), Louise Firth (University of Plymouth, UK)
Coordinator: Yihui Zhang (Xiamen University, China)

This session will be related to the biological invasions in estuarine and coastal ecosystems with the putative impacts that non-indigenous species (NIS) might exert on ecosystem processes and services. This central topic unfolds in several subtopics - such as (though not restricted to) documentation of species introduction, establishment and spread; the interplay of NIS with native species (e.g. biotic interactions, population dynamics, genetic diversity); how NIS affect the abiotic environment (e.g. ecosystem engineering, nutrient budgets); how NIS shift the goods and services that estuarine and coastal ecosystems provide (e.g. fisheries; management- including monitoring and eradication programs); analysis of vectors of invasion, and/or efficacy and impacts of attempts to control. Works covering these topics will be considered in this session.

3. Global Change and Evolutionary Adaptation

Conveners: Oliver Bossdorf (University of Tübingen, Germany), Suhua Shi (Sun Yat-sen University, China)
Coordinator: Yuanye Zhang (Xiamen University, China)

Recognizing evolution can occur at ecological timescales motivates studies on how evolutionary adaptation can help species to counter stressful conditions or realize ecological opportunities under global changes. This section aims to promote interdisciplinary studies between ecology and evolution and provide conservation insights under global changes. We welcome presentations of the latest research in understanding the drivers, patterns, consequences, and mechanisms of evolution under global changes. Potential topics also include how our understanding of evolution provide insights into population persistence, species extinction, community assembly, ecosystem functioning, ecosystem management, and conversion policy.

4. Long Term Ecological Research for Coastal Ecosystems

Conveners: Steven Pennings (University of Houston, USA), John Kominoski (Florida International University, USA)
Coordinator: Xudong Zhu (Xiamen University, China)

This session aims to cover LTER research for coastal ecosystems, including but not limited to wetlands, estuaries, and coastal waters. The presentations are expected to be centered on the latest LTER studies applying observation, experiment, and/or model approaches to examine long-term responses and adaptions of coastal ecosystem structure, function, and services to global change, across various spatial and temporal scales. Potential topics include emerging observation technologies (e.g., eddy covariance, unmanned aerial vehicle, satellite remote sensing), model applications (e.g., process-based models and data-driven models), data-model fusion studies, etc. Presentations on LTER site facilities, data management/sharing, cross-site collaboration, and observation network development are also welcome.

5. Land-based Human Activity and Sustainable Coastal Development

Conveners: Venu Ittekkot (University of Bremen, Germany) ,Andrew C. Johnson (Centre for Ecology & Hydrology, UK)
Coordinator: Yangfan Li, Pei Wang (Xiamen University)

This session is aimed at identifying the process, mechanism and key factors of land-based human activities like increasing urbanization and industrialization in the coastal regions, and exploring the goals, targets and paths for sustainable coastal development. Human activities and settlements in coastal regions can have both positive and negative impacts on near shore ecosystems. The impacts of coastal development may be direct (e.g., land filling, dredging, coral and sand mining for construction) or indirect (e.g., increased runoff of sediment and pollutants). This session will take two half days, with speakers covering issues related to human activities in coastal regions, including land-based pollution and its ecological impacts, interaction between human intervention and ecosystem adaptation, pathways for the transfer of major elements from land to sea, mechanisms and key factors for coastal ecosystem resilience, coastal urbanization and its impacts, and the delivery of Sustainable Development Goals (SDGs) in coastal regions. Speakers will talk about the latest research progress and future directions for research and collaboration.

6. Integrated Coastal Ecosystem Management

Conveners: Chris McOwen (UNEP-WCMC, UK),Angel Borja (AZTI, Spain)
Coordinator: Qinhua Fang (Xiamen University, China)

This session aims to promote the interdisciplinary studies of the science-policy interface for integrated coastal ecosystem management. The presentations, including innovative theories, practical approaches, and up-to-date case studies in various contexts around the world are all welcome. Potential topics include but are not limited to marine spatial planning and marine protected areas, evaluation and payments of ecosystem services, natural capital and blue economy, ecological civilization and its implications, as well as integrated coastal and ocean management and sustainable coastal development.
