*Speakers: *Erin Eggleston, Assistant Professor of Biology at Middlebury
College.

*Description: *Cyanobacteria play critically important roles on Earth but
under certain conditions lead to cyanobacterial harmful algal blooms
(CHABs). Like all other cells cyanobacteria can be infected with viruses,
but relatively little is known about the roles viruses play in CHAB
dynamics. We are working to characterize these relationships, and how they
may influence nutrient cycling and CHAB formation, maintenance, and
collapse. Additionally, Lake Champlain experiences increasingly warm and
ice-free winter conditions. Initial evidence from temperate lakes suggests
that under-ice microbial dynamics play larger roles than initially
anticipated in nutrient cycling. This work investigated the microbial
ecology of CHAB communities across seasons to observe these dynamics.
Preliminary data show interesting microbial and viral populations trends by
season, as well as functional influence of viruses on carbon metabolism in
summer CHABs.
