We collected molecular data using Sanger sequencing. This provided us with the nucleotide base order in the individuals targeted DNA sequence.
STEP 1: Extraction
DNA was extracted from the femur of each individual specimen using enzymatic digestion with proteinase K.
Step 2: Polymerase Chain Reaction (PCR)
Polymerase Chain Reaction (PCR) was used to amplify the COII gene region of the mitochondrial DNA
Step 3: Gel Electrophoresis
Gel electrophoresis was performed to confirm correct amplification and duplication of the targeted gene. Each sample was stained and run alongside a DNA ladder. The negatively charged DNA fragments migrate down the gel to the positive side
Step 4: Automated Sequencer
The amplified DNA was then sequenced using an automated sequencer to determine the nucleotide base pairs and their order
Step 5: Visualizing the Molecular Data
DNA sequences were use to create a phylogenetic tree using the R package XXX.
Closely related species (Arphia simplex, Meteor nevadensis, Anconia integra and Chortophaga australior) were used as outgroups.
