Although the south-western Australian region is recognised as a global biodiversity hotspot, there are still significant gaps in our understanding of the biodiversity of this region. We present a phylogenetic study of the heath dragons (Rankinia adelaidensis and R. parviceps) from this region, incorporating a 1612-bp section of mtDNA and two nuclear introns, Gapdh (~244 bp) and Enol (~330 bp). In addition, we present a generic-level analysis of three gene regions (mtDNA, Gapdh, BDNF), which provides clear evidence that Rankinia adelaidensis and R. parviceps are not closely related to Rankinia diemensis from eastern Australia. Instead, the heath dragons are strongly supported as forming a clade with the genus Ctenophorus. In addition, we find that there are significant levels of haplotype divergence between currently recognised subspecies of the heath dragons (R. a. adelaidensis, R. a. chapmani, R. p. parviceps, R. p. butleri). We suggest that the genetic divergences between subspecies result from geographic isolation in allopatry owing to habitat preferences, followed by drift and/or selection. On the basis of these deep divergences and consistent morphological differences between subspecies, we recommend elevating all taxa to full species, and provide a taxonomic revision of the genera Rankinia and Ctenophorus.

First Time

The Strait of Messina is located at the centre of the Mediterranean Sea and is considered a biodiversity hotspot and an obligatory seasonal passage for different pelagic species such as sharks, marine mammals, and billfishes. For the first time, in the Strait of Messina, our research group tagged a Mediterranean spearfish (Tetrapturus belone) using a pop-up satellite archival tag (PSAT). The observation of abiotic parameters (depth, light, and temperature) recorded by the PSAT confirmed that the tagged specimen was predated after about nine hours. The tag was then regurgitated 14 days after the tag deployment date. The analysis of collected data seems to indicate that the predator may be an ectothermic shark, most likely the bluntnose sixgill shark (Hexanchus griseus).
