Biological invasions can have important impacts on the ecology and behavior of native species. With increasing globalization and climate change, new invasions by nonnative species are constantly occurring. Wild pigs are a highly adaptable invasive ungulate in North America that have been found to contribute to large amounts of habitat destruction, agricultural loss, damage to infrastructure, and disease spread. Understanding how wild pig presence and population parameters will affect native species is necessary fo continued conservation efforts. Given these widespread impacts, the areas where wild pigs are affecting native species still need exploration. Using camera trapping arrays, native species communities in regional and nationwide locations which were both invaded and uninvaded by wild pigs were intermittently monitored for a four-year period. First, I sought to determine the effects of wild pig invasion on native species behavior to understand how their presence could affect monitoring and occurrence of native species. Next, I investigated the impacts increased average temperatures had on the detection of native species and wild pigs. Lastly, I developed a method for more accurately estimating the abundance of unmarked wild pigs with camera traps. Overall, the occurrence of wild pigs had a significant effect on some of the native species' behavior in the form of altered diel activity regimes. Temperature was also found to influence the detection of native species but only rarely was it a factor in the detection of wild pigs. Lastly, the new method for estimating abundance of unmarked wild pigs was able to accurately estimate simulated abundance estimates, however there was slight overestimations in some instances. This research will advance the knowledge of not only impacts associated with wild pig invasion, but also for invasive mammals in general. These methods will be able to assist other researchers in monitoring invasive and native animal populations and improve estimates of population dynamics when animals are not able to be individually identified.
