Determining How Anthropogenic Change Filters Biological Communities And How Species Modify Their Traits In Response To Urbanization, Kristopher Warren Row Aug 2023

Determining How Anthropogenic Change Filters Biological Communities And How Species Modify Their Traits In Response To Urbanization, Kristopher Warren Row

Biology Dissertations

Humans are significantly altering the environment at an alarming pace, leading to a reduction in species diversity. This transformation has created modified habitats where some species struggle to survive, while a few others not only manage to survive but thrive. One of the most drastic forms of habitat modification is urbanization, which is spreading worldwide and contributing to the decline of biodiversity. Urbanization has given rise to urban-tolerant species that differ ecologically from species that avoid urban areas across various niche dimensions. These urban-tolerant species must adapt to changes in food sources, microhabitat conditions, and alterations in physical habitat structures. …

Biodiversity In The Anthropocene, Understanding The Impacts Of Land-Use Change, And Species Interactions., Alexander H. Murray

Biology Dissertations

The extent of human influences on the environment and biodiversity has led to naming our current time period the Anthropocene. A primary way in which humans impact biodiversity is through habitat modification. Despite the knowledge that habitat modification is negative for many species, we still don’t understand why some species are able to persist despite habitat modification while others do not. In my first chapter I used a trait-based approach to understand what determines species’ sensitivity to habitat modification. Trait-based approaches from different regions often disagree on the importance of the same traits, and I thought climate and land use …
