whether certain species are endemic to particular environments.
The environments that I have been working in include the Ross Sea,
Antarctica, the Sargasso Sea and the San Pedro Channel.
My participation in this cruise will allow me to expand my genetic
analyses to another extreme environment the hydrothermal
vents. The project that I will be doing will include the concentration
of very large volumes of water to microscopically assess the morphological
diversity of the sample, determine whether the organisms are in
a dormant or an active state, and perform in situ hybridization
analyses with recovered gene sequences. In addition, the recovered
gene sequences can be used to identify the genetic relationships
between the organisms from these samples and those from other vent
and temperate samples. In this manner, I hope to begin correlating
genetic identification with morphological descriptions of the protozoa
living at these sites.
