Variables in the Introduction of the Species, Streptocephalus sealii, Spinytail Fairy Shrimp into a Local Seasonal Wetland (2015) The research question addressed in this capstone is what factors play a role in the introduction of a wingless aquatic invertebrate to a recently restored mitigation wetland. The motivation for this capstone was the discovery of a fairy shrimp, Streptocephalus sealii in a Rosemount, Minnesota wetland in 2012. This organism was previously recorded from two other sites in Minnesota at least 35 miles from this location. Its appearance in a mitigation wetland generated questions as to whether restoration materials brought in the species or the mitigation created the environment in which the organism could thrive. This study investigates both of these ideas as well as a documentation of the mitigation wetlands history. Key Words: mitigation, vernal pool, fairy shrimp, introduced species, hydric soil VARIABLES IN THE INTRODUCTION OF THE SPECIES, Streptocephalus sealii, SPINYTAIL FAIRY SHRIMP INTO A LOCAL SEASONAL WETLAND By Jane A.
