SICB 2019: Urban Gulls Alter FID and Flight Behaviors
Urbanization is a global form of habitat change that alters native habits and either excludes the animals that live there or forces them to acclimate to novel environments. Altering behavioral strategies can allow individuals to quickly acclimate and successfully colonize…

SICB 2019: Urbanization Affects the Stress Physiology and Life History of Stream Fish
Urban environments are on the rise, bringing with them pollutants from run-off which alters water temperature, chemistry, and hydrology, ultimately driving a decrease in biodiversity. These disturbances can affect the physiological stress response of fishes by increasing or dysregulating their primary…
