TY - JOUR TI - Preventing biological invasions by understanding the processes leading to establishment DO - https://doi.org/doi:10.7282/t3-tgaz-2142 PY - 2019 AB - Invasive species are a leading cause of animal extinctions and result in billions of dollars ($US) in economic damages globally. Understanding the processes involved in biological invasions can aid in finding efficient and effective policy and management solutions. In this dissertation, I explore three mechanisms that can prevent invasive species from establishing. First, within the context of the most common pathway for invasive vertebrate species, I document factors related to the release of exotic pets into the wild by their owners. Second, I develop a method to calculate the reduction of propagule pressure required to lower the establishment probability for introduced non-native populations. Last, I explore an overlooked assumption of the propagule pressure effect and calculate the how establishment probability is altered when spatial and temporal independence of introduction events is violated. The results I highlight, and the methods I developed, are critical in slowing the rate at which invasive species are establishing worldwide.
