An Analysis of the Effects of Temperature and Other Environmental Factors on Microorganismal Productivity within Aquatic Ecosystems using Long-Term Data from Various Lter and Ilter Sites
Global climate change is a phenomenon resulting in more extreme weather patterns and species diversity loss. In this study, I explore the impacts of climate change on regional patterns of microbial productivity. Variation in microbial productivity was explained using temperature, salinity, and disso...

Global climate change is a phenomenon resulting in more extreme weather patterns and species diversity loss.
