Ecosystems are defined by the complex interactions of their highly interconnected biotic, chemical, and physical components. The diversity of component parts and their multitude of possible connections makes deep knowledge of ecosystem mechanics beyond the reach of any one person. Thus it is imperative that ecologists work together within and across teams and communities to understand our vital and changing ecosystems. In this session we invite speakers who have achieved a deeper understanding of ecosystems through teamwork and team-building to share lessons learned on how to build thriving research communities. Speakers will share their experiences in developing research teams and networks that span a diverse range of topics, including model synthesis, data synthesis, manipulation experiments, sensor arrays, institutions, and communities. Speakers will also highlight the lessons learned from these networks that would not have been possible through individual work and provide recommendations for building new networks in an increasingly connected world.
