Symbioses in a changing ocean:
Keystone interactions from microbial to global scales

Rapid environmental changes are altering ecological communities across scales. Understanding and predicting future ecosystem states is essential for developing mitigation and conservation strategies. To uncover fundamental ecological phenomena, I study sentinel species and keystone ecological interactions, working from microscopic to global scales.

In this seminar, I will discuss my work on dynamic symbiotic interactions. Symbioses run the gamut from parasitism to mutualism; for individual interactions, environmental conditions can shift the balance between parasitism and mutualism. Here, I present work from two study systems – coral symbioses and fish parasitism – in the context of environmental change. I will discuss multiple approaches for determining what tips the balance between mutualism and parasitism, and implications of these findings for potential conservation approaches.

Danielle Claar is a NOAA Climate and Global Change postdoctoral fellow at the University of Washington’s School of Aquatic and Fishery Sciences, where her research focuses on climate impacts on reef fish parasitism and disease. She obtained her PhD at the University of Victoria in 2019, where she studied coral survival and resilience during an unprecedented warming event. Her research uses multiple approaches to measure how symbioses and ecological communities respond to both local impacts and global change. She is a quantitative ecologist, harnessing high-throughput sequencing data of microbes, community and biodiversity modelling approaches, and satellite data to understand how ecosystem changes influence biological function.
