These datasets include the alignment of DNA sequences used to detect phylogenetic signal on species of Heligmosomoidea collected across North America and Siberia by the Beringia Coevolution Project. The dataset allowed the determination of species diversity in parasites of squirrels (_Citellinema_) and cricetine rodents (_Heligmosomoides_). The files include the alignments as described in the research article and the Maximum Likelihood tree for each dataset(combined, ITS and mitochondrial).
