Abstract
The field of invasion biology seeks to understand the factors that contribute towards a
non-native species’ invasion success (Reichard & White, 2003). It is well acknowledged that
differences in animal behavior are vital during multiple phases of the invasion process, especially
establishment and spread. Recent studies have shown that features like behavior tend to vary
throughout the area of invasion, contributing further towards success or failure (Bélouard et al.,
2019). However, genetic variation across invasion areas, particularly in arachnids, is still a
relatively unexplored factor. In this study, two genes of Pholcus manueli were examined. DNA
was extracted from 36 specimens collected across the U.S. invasion range. The relative genetic
distance between populations was determined through various methods of post-run analysis.
Results indicated that there was not a correlation between genetic and geographic distance, nor
was there a significant genetic difference between core and edge invasion areas.
