Abstract:

Dispersal is a key mechanism driving the geographic distribution of all species on Earth. However, dispersal ecology and theory are largely based on animal and plant systems, with efforts to include microbial dispersal only developing more recently. In fungi, numerous traits related to dispersal (e.g. spore and fruiting body morphology) are likely linked to fungal biogeographic patterns, but these hypotheses remain largely untested. This presentation examines the relatively uncharted discipline of fungal dispersal ecology. Will explore different methodologies to examine fungal dispersal including traits, leveraging global eDNA datasets, and LLMs.

Cameron P. Egan is an Associate Professor at the University of Southern California and a community ecologist whose research explores plant–fungal symbioses and their role in shaping biodiversity, ecosystem function, and resilience across natural and human-modified systems. His work integrates community ecology, microbial ecology, and ecological modelling to understand how belowground interactions influence aboveground ecological patterns, with a particular focus on mycorrhizal networks, dispersal processes, and environmental gradients. As co-PI of the fungal dispersal working group, he is excited to share the advances made through the collaboration and support provided by ESIIL (Environmental Data Science Innovation & Impact Lab).
