Identification Of Species

New Guinea tree kangaroos (Dendrolagus spp.) are unique arboreal macropodid marsupials mainly listed as critically endangered or endangered. The molecular systematics of Dendrolagus has not been fully resolved and is critical for the accurate identification of species and their evolutionary relationships. Matschie’s tree kangaroo (D. matschiei) and Goodfellow’s tree kangaroo (D. goodfellowi buergersi) share numerous morphological, physiological, and behavioural traits. We analysed the partial mitochondrial DNA cytochrome b gene for D. matschiei (n = 67), D. g. buergersi (n = 8), D. goodfellowi unidentified ssp. (n = 8), golden-mantled tree kangaroo (D. g. pulcherrimus; n = 1), and two additional New Guinea Dendrolagus taxa to determine whether D. matschiei and D. g. buergersi are sister taxa. D. matschiei and D. g. buergersi were not placed as sister taxa in our phylogenetic analyses; however, we were unable to analyse a known sample from a D. g. goodfellowi. We found initial genetic evidence that D. matschiei and the Lowland tree kangaroo (D. spadix) are sister taxa – they may have diverged after the formation of the Huon Peninsula of Papua New Guinea. Our results also support the elevation of D. g. pulcherrimus to a full species. An improved understanding of Dendrolagus molecular systematics will contribute substantially to their conservation.

Systematic Composition

From morphogical and molecular data we reconsider the systematic composition of the Lake Baikal amphipod genusBabr Kamaltynov & Väinölä (Pallaseidae), until recently part of Pallasea Bate. The morphology of Babr is relativelyuniform, but both allozyme and mitochondrial DNA data recognize a deep split into two lineages (Nei's D = 1.1,uncorrected COI sequence divergence 17 %). These correspond with the two species B. baikali (Stebbing) andB. nigromaculatus (Dorogostaisky), which both are found to be widespread throughout the lake but show different depthpreferences. We found no support for the third proposed taxon B. inermis (Sowinsky), and consider it a synonym ofB. baikali. Revised morphological diagnoses for the genus and the two species are presented, including newmorphological characters. In terms of mtDNA, B. baikali is further subdivided into clearly separate geographical lineages, for which no morphological correspondence was however established.

AbstractRanid frogs of the genus Amolops occur in Southeast Asia and are typically found near waterfalls. Their phylogenetic relationships have not been resolved. We include 2,213 aligned nucleotide sites of the 12S, 16S and tRNAval gene regions of the mitochondrial DNA genome from 43 individuals of Chinese and Vietnamese Amolops, Huia, Hylarana, Meristogenys, Odorrana and Rana. The outgroup species were from the genera Chaparana, Limnonectes, Nanorana, and Paa. The data were analyzed within the framework of a refutationist philosophy using maximum parsimony. Four clades of waterfall frogs were resolved. Meristogenys was not resolved as the sister group to either Huia nor Amolops. The hypothesis of evolutionary relationships placed Amolops chapaensis and Huia nasica in the genus Odorrana.
