The range of DNA sequences used to study the interrelationships major arthropod groups (chelicerates, myriapods, hexapods and crustaceans) is limited. Here we investigate value two genes not previously employed in phylogenetics. Histone H3 data were collected for 31 species small nuclear ribonucleic acid U2 29 species. provided a total 460 sites 192 parsimony-informative characters. analyses showed substantial codon usage bias, but had low consistency index (0.26). Consistency indices higher...
The koala, the only extant species of marsupial family Phascolarctidae, is classified as 'vulnerable' due to habitat loss and widespread disease. We sequenced koala genome, producing a complete contiguous reference including centromeres. reveal that koala's ability detoxify eucalypt foliage may be expansions within cytochrome P450 gene family, its smell, taste moderate ingestion plant secondary metabolites in vomeronasal receptors. characterized novel lactation proteins protect young pouch...
Sequence data for two segments of 28S and Histone H3 from 36 gastropod taxa, a chiton, bivalves Nautilus are used to test recently published morphology‐based phylogenetic hypotheses relationships. Statistical results suggest that the accuracy available could be improved. The support monophyly Patellogastropoda (true limpets), Euthyneura ‘higher’ vetigastropods polyphyly ‘Cocculiniformia’. division gastropods into major clades (Eogastropoda Orthogastropoda) as has been proposed on...
Morphological, developmental, ultrastructural, and gene order characters are catalogued for the same set of arthropod terminals as we have scored in a recent study histone H3 U2 snRNA sequences (D. J. Colgan et al., 1998, Aust. Zool. 46, 419-437). We examine implications separate simultaneous analyses sequence non-sequence data relationships. The most parsimonious trees based on 211 (273 apomorphic states) support traditional higher taxa clades, including Mandibulata, Crustacea, Atelocerata,...
The Cerithioidea is an ecologically important superfamily of basal Caenogastropoda with speciose marine, brackish water, and freshwater lineages primarily in tropical, subtropical, warm temperate regions the world. They often represent significant components communities where they occur have given rise to several spectacular endemic radiations rivers ancient lakes. Earlier attempts resolve phylogenetic history group been based on smaller taxon character subsets incongruent results. Here...
Significant differences remain between gastropod phylogenetic hypotheses based on morphological and molecular datasets. We collected additional data from three gene segments (28S rDNA expansion region D1 (36 taxa plus two GenBank), cytochrome c oxidase subunit 1 (35 species one Genbank) small nuclear RNA U2 (24 species)). These were combined with available for the same histone H3 other of 28S rDNA. Analyses these using cladistic, maximum likelihood or Bayesian methodologies conducted in an...
The koala, Phascolarctos cinereus, is a biologically unique and evolutionarily distinct Australian arboreal marsupial. goal of this study was to sequence the transcriptome from several tissues two geographically separate koalas, create first comprehensive catalog annotated transcripts for species, enabling detailed analysis attributes threatened native marsupial, including infection by koala retrovirus. RNA-Seq data generated range one male female assembled de novo into using Velvet-Oases....
DNA sequence data from for histone H3 (34 species), U2 snRNA species) and two segments (D1 D9–10 expansion regions) of 28S rDNA (28 26 species, respectively) have been collected to investigate the relationships polychaetes. Representatives all major morphologically identified clades were used, as well members Sipuncula, Echiura, Turbellaria, Clitellata Siboglinidae (formerly phyla Pogonophora Vestimentifera). Maximum parsimony analyses separate sets gave conflicting results none conformed...
The integration of molecular and morphological approaches has produced substantial progress in understanding the higher classification most major invertebrate groups. striking exception to this is Polychaeta. Neither membership nor group been robustly established. Major inconsistencies exist between only comprehensive cladistic analysis Polychaeta using data DNA sequence studies covering all or part taxon. We have compiled a dataset available nearly complete 18S ribosomal sequences collected...
A combination of intrinsic and extrinsic factors, such as dispersal capabilities or opportunities, habitat preferences, life history attributes, physiological availability, biotic abiotic interactions historical determine not only the geographic distribution a taxon, but its propensity for population differentiation speciation. Freshwater hydrobiid snails have little ability to disperse outside their immediate opportunities accidental are limited. Long-term permanency is critical existence...
Electrophoretic surveys of 10 species hydrobiid snails in two indigenous genera (Fonscochlea and Trochidrobia) living arid-zone artesian ‘mound’ springs are reported. The study is based on 96 populations 32 different representing 18 spring groups the Lake Eyre Supergroup, northern South Australia. species-level taxonomy these snails, previously morphological differences alone, was tested modified. were examined within five clear-cut groups: largest, fully aquatic accepta F. aquatica) treated...
Terebellomorpha is a clade of predominantly tube-dwelling polychaetes, some whose species are very abundant and habitats range from shallow to deep waters. The group contains five families (Terebellidae, Ampharetidae, Pectinariidae, Trichobranchidae Alvinellidae). This study their inter-relationships uses DNA sequence data gene segments. Including outgroups, sequences were available for 15 U2 snRNA, 14 Histone H3, 23 the D1 expansion region 28S rDNA, D9-10 rDNA 17 subunit I cytochrome...
Two species of small pearl oysters have long been recorded from New South Wales but these proved difficult to separate on the basis shell characters. An electrophoretic and morphological study has confirmed presence two genetic species. Four loci (of fourteen scored) show little overlap in suite allozymes present There is a very low incidence heterozygotes taxon-characteristic at loci, indicating that interbreeding between infrequent. broad local sympatry species, with both occurring all one...
