Connectivity is a term used across disciplines to describe the transfer of water, energy, sediment, genes, and organisms across boundaries. Such a broad usage of the term connectivity can generate confusion but also has the potential to facilitate an interdisciplinary discussion about how the concept is applied across scales of ecological organization. Hydrologic connectivity, sediment connectivity, habitat connectivity, and population connectivity all have distinct definitions but may share important drivers and implications. For instance, for many disciplines the concept is central to understanding dynamics that can either maintain or disrupt ecosystem stability. This session will bring together scientists with disparate definitions of ecological connectivity to discuss the importance of the concept in diverse ecosystems. Talks will address how connectivity may be critical to understanding ecosystem responses to a changing world. Speakers will be asked to consider the following questions: How do you define connectivity? How might your concept of connectivity apply to other systems or other disciplines? How do you anticipate connectivity changing in your system? What are the ecological implications of altered connectivity? This session will challenge ESA attendees to consider why diverse ecosystems may respond differently to changes in connectivity, and will foster conversation on the best way for ecologists to approach this interdisciplinary concept.
