Whereas terrestrial animal populations might show genetic connectivity within a continent, marine species, such as hermatypic corals, may have connectivity stretching to all corners of the planet. We quantified the genetic variability within and among populations of the widespread scleractinian coral, Plesiastrea versipora along the eastern Australian seaboard (4145 km) and the Ryukyu Archipela...

In many species, individuals discriminate among sexual signals of conspecific populations in the contexts of mate choice and male-male competition. Differences in signals among populations (geographical variation) are in part the result of signal evolution within populations (temporal variation). Understanding the relative effect of temporal and geographical signal variation on signal salience ...

In Australian populations of barramundi Lates calcarifer, phylogenetic reconstruction of mtDNA sequences provided evidence of significant historical levels of gene flow, despite the substantial structuring of contemporary populations. The geographical pattern of mtDNA sequences among the populations was not congruent with previous evidence of a major disjunction between western and eastern popu...
