We tested if grasshopper species varied based on locations with constant human interaction vs. locations with little to no human interaction within Sanpete county. Due to how close, (a 6 mile radius), the collection locations are, it was logically reasoned that there will be no differences in grasshopper species between Ephraim and Manti Utah.
This study was performed with grasshoppers collected in Sanpete County: specifically, the town of Ephraim, Ephraim canyon, the town of Manti, and Manti canyon. To do this, we collected grasshoppers from each of the mentioned locations, extracted the DNA samples by humanely freezing the grasshoppers and collected small amounts of the grasshoppers, amplified the DNA samples using PCR, and sequenced the PCR products to help identify the grasshopper species collected using BLAST.
Our experiment results showed that there was a large variation of species collected, as well as many similar species were present in all collection locations. Ephraim housing and Ephraim canyon only had one type of species present (Melanoplus sanguinipes), while Manti housing showed three other species (Melanoplus differentialis, Dissosteira carolina, Trimerotropis pallidipennis), and Manti canyon showed another species type (Trimerotropis cincta). This suggests that there is more variation within Manti housing and Manti canyon, no variation within Ephraim housing and Ephraim canyon, and only some variation between Manti and Ephraim.
