Unravelling the taxonomy and identification of a problematic group of benthic fishes from tropical rivers (Gobiidae: Glossogobius)

Michael P. Hammer, Laura Taillebois, Alison J. King, David A. Crook, more

Journal of Fish Biology > 99 > 1 > 87 - 100

Flathead gobies (genus Glossogobius) include c. 40 small‐ to medium‐sized benthic fishes found primarily in freshwater habitats across the Indo‐Pacific, having biodiversity value as well as cultural and economic value as food fishes, especially in developing countries. To help resolve considerable confusion regarding the identification of some of the larger‐growing Glossogobius species, a systematic...

DNA barcoding of microgastrine parasitoid wasps (Hymenoptera: Braconidae) using high‐throughput methods more than doubles the number of species known for Australia

Erinn P. Fagan‐Jeffries, Steven J.B. Cooper, Terry Bertozzi, Tessa M. Bradford, more

Molecular Ecology Resources > 18 > 5 > 1132 - 1143

The Microgastrinae are a hugely diverse subfamily of endoparasitoid wasps of lepidopteran caterpillars. They are important in agriculture as biological control agents and play a significant ecological role in the regulation of caterpillar populations. Whilst the group has been the focus of intensive rearing and DNA barcoding studies in the Northern Hemisphere, the Australian fauna has received little...

Horizontal transfer of BovB and L1 retrotransposons in eukaryotes

Atma M. Ivancevic, R. Daniel Kortschak, Terry Bertozzi, David L. Adelson

Genome Biology > 2018 > 19 > 1 > 1-13

Background Transposable elements (TEs) are mobile DNA sequences, colloquially known as jumping genes because of their ability to replicate to new genomic locations. TEs can jump between organisms or species when given a vector of transfer, such as a tick or virus, in a process known as horizontal transfer. Here, we propose that LINE-1 (L1) and Bovine-B (BovB), the two most abundant TE families in...

Characterisation of major histocompatibility complex class I transcripts in an Australian dragon lizard

Jessica Hacking, Terry Bertozzi, Adnan Moussalli, Tessa Bradford, more

Developmental & Comparative Immunology > 2018 > 84 > C > 164-171

Characterisation of squamate major histocompatibility complex (MHC) genes has lagged behind other taxonomic groups. MHC genes encode cell-surface glycoproteins that present self- and pathogen-derived peptides to T cells and play a critical role in pathogen recognition. Here we characterise MHC class I transcripts for an agamid lizard (Ctenophorus decresii) and investigate the evolution of MHC class...

Molecular systematics and biodiversity of oniscidean isopods in the groundwater calcretes of central Western Australia

Mohammad Javidkar, Steven J.B. Cooper, Rachael A. King, William F. Humphreys, more

Molecular Phylogenetics and Evolution > 2016 > 104 > C > 83-98

Groundwater calcrete aquifers of central Western Australia have been shown to contain a high diversity of stygobiont (subterranean aquatic) invertebrates, with each species confined to an individual calcrete and the entire system resembling a ‘subterranean archipelago’ containing hundreds of isolated calcretes. Here, we utilised alternative sampling techniques above the water table and uncovered a...

MHC in a monogamous lizard – Characterization of class I MHC genes in the Australian skink Tiliqua rugosa

Talat Hojat Ansari, Terry Bertozzi, Robert D. Miller, Michael G. Gardner

Developmental and Comparative Immunology > 2015 > 53 > 2 > 320-327

The major histocompatibility complex (MHC) is a highly variable region of vertebrate genomes that encodes cellular proteins involved in the immune response. In addition to the benefits of MHC research in understanding the genetic basis of host resistance to disease, the MHC is an ideal candidate for studying genetic diversity under strong natural selection. However, the MHC of many non-model vertebrate...

Development of 15 microsatellite loci from mulloway, Argyrosomus japonicus (Pisces: Sciaenidae) using next generation sequencing and an assessment of their cross amplification in other sciaenids

Thomas C. Barnes, Christopher Izzo, Terry Bertozzi, Kathleen M. Saint, more

Conservation Genetics Resources > 2014 > 6 > 2 > 345-348

Next generation sequencing was used to develop 15 new polymorphic microsatellite markers for the commercially and recreationally important fish mulloway (Argyrosomus japonicus). Improved knowledge of the genetic structure of the species is necessary for fisheries and environmental management. In a population of mulloway, we found that genetic variation and heterozygosity were high in most of our loci...

Multilocus phylogeny and recent rapid radiation of the viviparous sea snakes (Elapidae: Hydrophiinae)

Kate L. Sanders, Michael S.Y. Lee, Mumpuni, Terry Bertozzi, more

Molecular Phylogenetics and Evolution > 2013 > 66 > 3 > 575-591

The viviparous sea snakes (Hydrophiinae: Hydrophiini) comprise a young but morphologically and ecologically diverse clade distributed throughout the Indo-Pacific. Despite presenting a very promising model for marine diversification studies, many relationships among the 62 species and 16 genera in Hydrophiini remain unresolved. Here, we extend previous taxonomic and genomic sampling for Hydrophiini...

Panmixia supports divergence with gene flow in Darwin’s small ground finch, Geospiza fuliginosa, on Santa Cruz, Galápagos Islands

TOBY H. GALLIGAN, STEPHEN C. DONNELLAN, FRANK J. SULLOWAY, ALISON J. FITCH, more

Molecular Ecology > 21 > 9 > 2106 - 2115

The divergence‐with‐gene‐flow model of speciation has a strong theoretical basis with a growing number of plausible examples in nature, but remains hotly debated. Darwin’s finches of the Galápagos Archipelago have played an important role in our understanding of speciation processes. Recent studies suggest that this group may also provide insights into speciation via divergence with gene flow. On...

Development of eight microsatellite loci from the Green and Golden Bell Frog (Litoria aurea) through GS-FLX pyrosequencing and cross-amplification with other species of the Litoria aurea species group

Matthew L. DeBoo, Terry Bertozzi, Stephen Donnellan, Michael J. Mahony

Conservation Genetics Resources > 2012 > 4 > 4 > 1003-1005

A next generation sequencing approach was used to develop eight new microsatellite loci for the endangered Green and Golden Bell Frog (GGBF) Litoria aurea. Microsatellite loci were developed from six individuals and tested on another 20. Genetic variation and heterozygosity was high in most loci (mean number of alleles per locus = 7.785; mean heterozygosity = 0.785375). Samples from six other closely...

Genetic and morphological divergence in island and mainland birds: Informing conservation priorities

Rachael Y. Dudaniec, Beth E. Schlotfeldt, Terry Bertozzi, Stephen C. Donnellan, more

Biological Conservation > 2011 > 144 > 12 > 2902-2912

Evolutionary processes can complicate conservation efforts for species with uncertain taxonomic classifications and discrete geographic populations. Discordant morphological and genetic patterns across the geographic range of species further calls for the identification of evolutionary significant units for conservation. Using island and mainland populations of a small Australian passerine (the superb...

Telomere length and age in pinnipeds: The endangered Australian sea lion as a case study

Christopher Izzo, Derek J. Hamer, Terry Bertozzi, Stephen C. Donnellan, more

Marine Mammal Science > 27 > 4 > 841 - 851

Telomeres are the protective caps at the ends of all eukaryotic chromosomes. Because DNA replication of chromosome ends is incomplete, telomeres undergo sequence loss with each cell division resulting in the progressive shortening of their lengths. Telomere shortening with age is known from terrestrial mammals. We test whether this pattern is shared by marine mammals, by comparing telomere lengths...

Closing the mitochondrial circle on paraphyly of the Monogenea (Platyhelminthes) infers evolution in the diet of parasitic flatworms

Elizabeth M. Perkins, Steve C. Donnellan, Terry Bertozzi, Ian D. Whittington

International Journal for Parasitology > 2010 > 40 > 11 > 1237-1245

Relationships between the three classes of Neodermata (parasitic Platyhelminthes) are much debated and restrict our understanding of the evolution of parasitism and contingent adaptations. The historic view of a sister relationship between Cestoda and Monogenea (Cercomeromorphae; larvae bearing posterior hooks) has been dismissed and the weight of evidence against monogenean monophyly has mounted...

Looks can deceive: Molecular phylogeny of a family of flatworm ectoparasites (Monogenea: Capsalidae) does not reflect current morphological classification

Elizabeth M. Perkins, Steve C. Donnellan, Terry Bertozzi, Leslie A. Chisholm, more

Molecular Phylogenetics and Evolution > 2009 > 52 > 3 > 705-714

The morphological based taxonomy of highly derived parasite groups is likely to poorly reflect their evolutionary relationships. The taxonomy of the monogenean family Capsalidae, which comprises approximately 180 species of flatworm parasites that predominantly attach to external surfaces of chondrichthyan and teleost fishes, is based mainly on six morphological characters. The phylogenetic history...

Positive Selection in the N-Terminal Extramembrane Domain of Lung Surfactant Protein C (SP-C) in Marine Mammals

Natalie J. Foot, Sandra Orgeig, Stephen Donnellan, Terry Bertozzi, more

Journal of Molecular Evolution > 2007 > 65 > 1 > 12-22

Maximum-likelihood models of codon and amino acid substitution were used to analyze the lung-specific surfactant protein C (SP-C) from terrestrial, semi-aquatic, and diving mammals to identify lineages and amino acid sites under positive selection. Site models used the nonsynonymous/synonymous rate ratio (ω) as an indicator of selection pressure. Mechanistic models used physicochemical distances between...

Regeneration of almond from immature seed cotyledons

Phillip J. Ainsley, Freddi A. Hammerschlag, Terry Bertozzi, Graham G. Collins, more

Plant Cell, Tissue and Organ Culture (PCTOC) > 2001 > 67 > 3 > 221-226

Adventitious shoots were regenerated from immature cotyledons of four almond cultivars (`Ne Plus Ultra', `Nonpareil', `Carmel' and `Parkinson'). Open-pollinated fruit were collected from orchard-grown trees 100–115 days after full bloom. The proximal ends of the cotyledons were excised and the embryonic axes discarded. The effects of different concentrations of thidiazuron (TDZ) and indole-3-butyric...
