Tyler J. Kohler, Ph.D.
Researcher
I am an ecologist primarily interested in how freshwater microbial communities are formed, maintained, and interact with their world, especially within the context of the global climate crisis. At present, my research focuses on the community dynamics and biogeochemical cycling of benthic biofilms within glacier-fed streams.

I am mainly interested in the ecology, diversity, and biogeography of limno-terrestrial and aquatic diatoms (Bacillariophyceae) in polar and sub-polar regions, with a primary focus on Antarctica. Diatoms are eukaryotic unicellular algae present in almost every freshwater and terrestrial habitat (i.e. ponds, lakes, seepage areas, wet mosses and soils), and are one of the most diverse and abundant algal groups in Antarctica. Their species-specific morphological features, unique responses to different environmental conditions, and excellent preservation in sediments make diatoms excellent environmental indicators, useful in reconstructing climate changes, and model organisms for studying microbial species ranges and dispersal.
