Evolution Of Freshwater Crabs In Lake Malawi And The Lake Malawi Basin In The East African Rift Valley, Emily Johnson
Evolution Of Freshwater Crabs In Lake Malawi And The Lake Malawi Basin In The East African Rift Valley, Emily Johnson
All NMU Master's Theses
Lake Malawi is the southernmost lake in the East African Rift Valley and is home to a single species of freshwater crab, the Malawi Blue Crab. Little is known about species diversity and the phylogenetic relationships of the freshwater crabs of Lake Malawi, in contrast to the lake’s highly-diverse cichlid fish species flocks. The Malawi Blue Crab is presently assigned to Potamonautes lirrangensis (Rathbun, 1904) sensu lato, which was originally described from a single female specimen from the D. R. Congo. While the distribution of P. lirrangensis s. l. ranges from the Congo River basin to other Rift Valley lakes, …
A Phylogenetic Reevaluation Of The Genus Gavia (Aves: Gaviiformes) Using Next-Generation Sequencing, Quentin D. Sprengelmeyer
A Phylogenetic Reevaluation Of The Genus Gavia (Aves: Gaviiformes) Using Next-Generation Sequencing, Quentin D. Sprengelmeyer
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 …
