Abstract

The success of certain ant species in urban areas is largely unknown. Available food in the environment could affect the composition of ants in urban areas due to a possible relationship between ant physiology and diet. I tested the oil preference of ants as a function of available arthropod prey in urban environments. I hypothesized that as arthropod diversity decreased, ant abundance at oil baits would decrease. Oil is an important nutrient that can affect ant body functions and activities. Ant foraging activities have been found to be affected by lipid depletion. A food source where ants can obtain oil in an urban environment is arthropod prey. However, their diversity in urban areas can be low due to high impervious surfaces and low plant diversity. Decrease in available arthropods could lead to an oil scarcity for ants, who need to fulfill their lipid requirements. To balance their nutrients ants will forage for a scarce nutrient the colony needs. In my research baits of sugar, water, and different concentrations of oil were chosen at random and deployed throughout Chattanooga, TN. The oil baits consisted of either 0.1%, 0.5%, or 1%. The habitats the baits were deployed in were neighborhoods, parks, and street medians during the months of August and September. Pitfall traps were also setup to measure available arthropod prey. A linear regression was used to view ant abundance against arthropod diversity, temperature, and soil moisture. Results showed that in most oil bait concentrations, there was a downwards trend in ant abundance as arthropod diversity increased. This demonstrates a weak relationship between oil preference of ants in regard to arthropod diversity. While my hypothesis was not supported, further research can still be done on lipids role in ant adaptability.
