Species Distributions in a Changing Ocean: from Individuals to Communities
Dissertation Changing ocean conditions and biotic dependencies will influence commercially important species distributions in this interconnected and rapidly changing world. In this dissertation, I employ random forests, GAMs, and a generalized joint attribute modeling technique to study the impacts...

In this dissertation, I employ random forests, GAMs, and a generalized joint attribute modeling technique to study the impacts of climate, substrate, and fishing pressure on nearshore and pelagic species distributions and abundances in the North Atlantic. Through these approaches, I provide insights on which species have shifted environmental associations over time to more accurately model potential distribution shifts going forward. By comparing pelagic and nearshore species, I enlighten future modeling and management to the fact that not all species will behave the same in the face of a changing climate. By including fishing pressure in my models, I provide a better understanding of the relative effects of fishing pressure compared to climate on species distributions and abundances resulting in a more realistic and comprehensive understanding of the causes of shifting distributions. I utilize a joint modeling approach to help better inform the interspecific interactions that shape a species’ distribution. Finally, by modeling fishing gear as a species, I attempt to get us one step closer to an ecosystem approach to fisheries management.

Dissertation Changing ocean conditions and biotic dependencies will influence commercially important species distributions in this interconnected and rapidly changing world.

Through these approaches, I provide insights on which species have shifted environmental associations over time to more accurately model potential distribution shifts going forward.
