All NMU Master's Theses
Avian phylogenetic analysis based on DNA sequences, rather than morphological characters, has been used in recent decades to resolve systematic relationships. Advancements in molecular techniques have improved avian phylogenetics and have led to new insights on the relationships between and within taxa. Loons (Aves: Gaviiformes) are one of the oldest living lineages of birds, and the order includes five extant species. The morphological cladogram of Gavia placed G. arctica as a sister species to G. pacifica. However, a more recent study based on mtDNA resulted in a discordant tree splitting the G. arctica/G. pacifica clade, and …
