During her PhD, Tammy Ai Tian Ho investigated the effects of landscape connectivity and land use changes on arthropod populations. Her research focused on understanding how these environmental changes impact the distribution of arthropods populations, their genetic diversity, and their performance. She explored how the historical and current demographic changes affects genetic diversity. She also examined how structural and functional connectivity align. Additionally, her work looked at how arthropods respond to various stressors in urban environments and if their performance can be predicted from genetic diversity. Overall, her findings provide important insights into how landscape and land use changes can shape arthropod populations and evolutionary trajectories.

The PhD study was completed at the Centre for Ecological Genetics, Department of Biology - Genetics, Ecology and Evolution, Faculty of Natural Sciences, Aarhus University.
