Time Specific Population Dynamics Of Diatoms In Artificial Environments, Sydney Brown

Georgia College Student Research Events

Algae serve as the base trophic level of aquatic systems, energetically supporting entire aquatic communities. Culturing in a laboratory setting requires significant phycological background and ecological knowledge to mimic their natural environmental conditions. The purpose of this research was to explore the effects of time on the growth of algal cultures. Gomphonema parvulum was the species investigated, falling into a class of algae known as diatoms- which are defined by cell walls composed of silica. Due to this unique morphological feature, asexual reproduction results in a diminution of cell size each generation in which restoration of natural sizes is initiated …
