Smith Lecture – Barbara Spiecker, University of New Hampshire

The ebb and flow of tides shape coastlines, nourish ecosystems, and connect distant shores—offering profound lessons on resilience and adaptation. In this talk, I will explore the intersections of marine ecology, conservation policy, and community engagement.

Through the lens of marine ecology, we will examine my research on (1) the underlying mechanisms driving complex, multi-scale responses in benthic communities along the rocky shores of Oregon and New Zealand, and (2) the decadal review of California’s MPA network, using long-term monitoring data to uncover biological patterns in kelp forests and inform strategies for improved monitoring and adaptive management. Building on these scientific foundations, we will discuss how ecological research informs conservation policy and, in turn, necessitates active engagement—particularly from fishing and tribal communities.

We will also explore the deeper parallels between conflicts in science-public discourse and my work with marginalized communities. As a co-founder of a STEM nonprofit dedicated to fostering an inclusive world where both deaf and hearing individuals are empowered through accessible STEM education and communication, I have seen that many conflicts arise from a lack of human connection and the misconception that diversity is simply beneficial rather than essential for survival.

Just as marine ecosystems thrive through diversity, mutualism, and adaptation, so too must our approaches to conservation and science communication. By integrating research, policy, and inclusive engagement, we can build resilient networks—both ecological and human—that can withstand environmental change and drive lasting

transformation.
