Microorganisms are everywhere and aid in performing key functions across ecosystems. Within the soil and ocean, microorganisms are the regulators of nutrient transformations, while in host associated environments like the gut, they play an important role harvesting energy for their hosts. Understanding how these communities are structured and how perturbation alters them is the key to better understanding the role they play in their environment. To understand microbial dynamics across diverse ecosystems, I will demonstrate how various disturbances alter these communities in two soil ecosystems and in the gut of humans, non-human primates, and livestock. Specifically, I ask how climatic change alters soil microbial communities in eastern deciduous forests and semi-arid woodlands, and what role habitat fragmentation has on gut microbial communities in humans, non-human primates, and livestock in Kibale National Park.
