      abstract = {The introduction of invasive species, along with climate  change and habitat loss, are among the primary concerns for  the conservation of biodiversity at a global scale. In this  dissertation, I will assess the invasion process for  Psittaciformes, more generally known as parrots, parakeets,  cockatoos, and their kin. The introduction provides a  review for the development of the field of invasion  biology/ecology, as well as the relevance of parrots as  species that have established non-native populations on all  continents (except Antarctica). In Chapter 1, I review the  available data on the presence and invasive status of all  known non-native parrots at a global scale, to identify  what species are the most widespread, determine the extent  of their non-native distribution, and confirm what regions  have the most non-native parrot species. In Chapter 2, I  analyze the climatic and geographic determinants of  non-native parrot distributions outside of their native  range. Using species distribution models, the environmental  space occupied by these species will be compared between  their native and non-native range to determine whether they  are subsets of one another or if there is divergence  between the environmental niche spaces they occupy. These  results are validated with the incorporation of null models  trained using the same local environment data. In Chapter  3, I analyze the population genetics of the Monk Parakeet  (<i>Myiopsitta monachus</i>), one of the most widespread  non-native parrots, in order to confirm known patterns  about the origin and genetic diversity of its non-native  populations, including the previously unsampled populations  of Chicago, Illinois and Aguada, Puerto Rico.  This study  also examines the demographic history of the different  populations within the native range along with its only  congeneric species, the Cliff Parakeet (<i>Myiopsitta  luchsi</i>). Finally, I conclude the dissertation with a  discussion on the results uncovered throughout the  different chapters and the future projects I intend to  investigate.},
