| Title | Microbial ecology in deep freshwater lakes |
| Abstract |
Although freshwater ecosystems occupy a small portion of the earth’s
surface, these areas cycle petagrams of carbon per year globally and are
of great importance to humans as drinking water sources. Compared with
shallow freshwater ecosystems, deep lakes are fewer in number but are
larger in water volume and characterized as a place for important
biogeochemical cycles. Further, deep lakes are vulnerable to
anthropogenic impacts such as climate change and eutrophication.
Microbial processes are keys to understanding these ecological and
biogeochemical mechanisms. In this seminar, I will present an overview
of my works, which have been focusing on the unique diversity and
ecology of the bacterioplankton in deep freshwater ecosystems. Further,
I will introduce a future perspective of my research, which is going to
exploit a huge genomic dataset generated from multiple deep lakes to
challenge research topics beyond the microbial ecology of deep
freshwater lakes. |
