Feeding, clutch sizes, and the population dynamics of the Texas horned lizard, Phrynosoma cornutum

This thesis includes the development of a population dynamics model on the Texas Horned Lizard and in addition, a prey model involving interaction between the Texas Horned Lizard's main food source, harvester ants, and the non-native fire ant. The goal of this work is to understand the population dynamics of the Texas Horned Lizard, the horned lizard's relationship with its prey, and the effects of fire ants on the biological complexity of this population.
