GENE FLOW AND LARVAL DURATION IN SEVEN SPECIES OF FISH FROM THE GREAT BARRIER REEF
Calculations of gene flow between geographic regions predict panmixis for species with larval durations exceeding 1 mo, which suggests that fish larvae may use their greater mobility to retard, rather than enhance, dispersal due to hydrodynamic advection.
Transcriptomics of a Giant Freshwater Prawn (Macrobrachium rosenbergii): De Novo Assembly, Annotation and Marker Discovery

The transcriptome data reported here should provide an invaluable resource for improving the understanding of this species' genome structure and biology and instruct future functional studies to manipulate or select for genes influencing growth that should find practical applications in aquaculture breeding programs.
Pleistocene refugia in an arid landscape: analysis of a widely distributed Australian passerine

Overall mitochondrial DNA and microsatellite variation suggest that increasing aridity and Pleistocene refugia played a role in structuring populations of the Australian magpie; however, the dispersal ability and generalist habitat requirements may have facilitated the movement of magpies into an almost contiguous modern distribution across the continent.
Acanthochromis polyacanthus, a fish lacking larval dispersal, has genetically differentiated populations at local and regional scales on the Great Barrier Reef
Phenotypic and genotypic variation was surveyed on the basis of body colouration and 7 polymorphic loci in 19 populations from 5 regions of the central and southern Great Barrier Reef (GBR), which suggested a mixing of separate gene pools in this region and denies species status to the two morphotypes.
Characterisation of cellulase activity in the digestive system of the redclaw crayfish (Cherax quadricarinatus)
Findings suggest a significant endogenous component for redclaw cellulase activity, which was identified in the gastric fluid and digestive gland of the redclaw crayfish and demonstrated broad substrate specificity but showed a preference for soluble substrates.
A reappraisal of the evolution of Asian snakehead fishes (Pisces, Channidae) using molecular data from multiple genes and fossil calibration.

- 1 August 2010
A multi-locus molecular phylogeny was constructed and calibrated using two fossil dates to estimate divergence times within the Channidae, suggesting that after divergence from African taxa 40-50 Ma, evolution of Asian snakeheads has been heavily influenced by multiple broad scale dispersal events across India and Southeast Asia.
Patterns of molecular diversity in wild stocks of the redclaw crayfish (Cherax quadricarinatus) from northern Australia and Papua New Guinea: impacts of Plio-Pleistocene landscape evolution
It is demonstrated that wild redclaw crayfish populations consist of two highly divergent Australian lineages and two PNG lineages, and these congruent patterns most probably reflect periodic Plio-Pleistocene land and freshwater connections between Australia and New Guinea.
Assessment of Genetic Variation in Wild Populations of the Redclaw Crayfish (Cherax quadricarinatus, von Martens 1868) by Means of Allozyme and RAPD-PCR Markers
On a preliminary scale, RAPD fragments provided a useful tool for differentiating redclaw strains and constitute a marking system that could be used in crayfish genetic improvement programmes.
Quantitative genetic parameter estimates for body and carcass traits in a cultured stock of giant freshwater prawn (Macrobrachium rosenbergii) selected for harvest weight in Vietnam
It is suggested that selection for high harvest body weight based on breeding values estimated by fitting an animal model to the data can significantly improve mean body and carcass weight in GFP.
Evidence for fine geographical scale heterogeneity in gene frequencies in yellowfin tuna (Thunnus albacares) from the north Indian Ocean around Sri Lanka
Yellowfin tuna are currently considered by the member nations of the Indian Ocean Tuna Commission to constitute a single stock in the Indian Ocean due to a lack of knowledge about yellowfin tuna…
