Biodiversity of marine alveolates: examining species diversity and patterns in evolution

Alveolates are a diverse group of microeukaryotic organisms. In this seminar, I will be focusing on the rich diversity of marine alveolates that live together (as symbionts) with other organisms. Symbiosis itself is an interesting concept. These relationships between organisms can be benign (commensal), exhibit a common benefit (mutualism), or to the detriment of one of the partners (parasitism). This symbiotic spectrum has become more interesting with the addition of more modern genomic and proteomics data, highlighting some of the cellular machinery that has been modified to a symbiotic lifestyle. Other interesting concepts that are emerging from molecular data is species diversity and host specific: why are there so many symbiotic alveolates? Why not just have one generalist that is globally distributed? In the seminar I will also talk about some preliminary data on host/species relationships and what this has to do with an intriguing model for addressing parasitic alveolates: marine apicomplexans.

Assistant Professor, Hokkaido University

Dr. Kevin Wakeman started his work on marine alveolate at the University of British Columbia, Canada. After completing his PhD exploring the biodiversity, taxonomy and systematics of marine apicomplexan parasites, he moved to Okinawa, Japan where he worked on dinoflagellates (micro algae). Currently works as an Assistant Professor at Hokkaido University in Japan, where he works on the biodiversity and taxonomy of marine protists and marine invertebrates.

Unraveling how symbioses and indirect interactions influence biological communities

Ecologists often focus on species interactions to understand populations, but sometimes overlook the diversity of ways species can interact or how the effects of these interactions trickle through biological communities. I will discuss my research exploring how the presence of a species can influence other species and the ecosystems around them, highlighting the importance of symbioses, positive interactions, and indirect effects in structuring communities.
