Low genetic variability within and among populations of the brooding sponge Rhopaloeides odorabile on the central Great Barrier Reef

Abstract: The population genetic structure of the brooding sponge Rhopaloeides odorabile (Dictyoceratida) was examined at 3 polymorphic allozyme loci and the partial mitochondrial cytochrome oxidase sub-unit 1 gene (CO1) sequence (528 bp) from multiple sites across the central Great Barrier Reef (GBR), Australia. Distances between sampled sites ranged from a few 100 metres to 140 km. Observed levels of allozyme variation were generally low, and there were only minor differences in allozyme allele frequencies evident bet… Show more

“…The lack of intraspecific variation in the Mediterranean data set detected with COI sequences is in accordance with recent reports in Porifera (Duran et al. 2004b; Whalan et al. 2008; López‐Legentil & Pawlik 2009—but see the study by DeBiasse et al.…”

“…2011). We argue that hydrographic patterns can influence the dispersion potential of propagation vectors and, consequently, either pose barriers to gene flow, or potentially override limitations posed by distance and seascape features, and promote genetic admixture (Whalan et al. 2008).…”

“…Female reproduction for offshore R. odorabile specimens was higher, with larger oocytes and a reproductive index of oocytes, embryos and larvae more than an order of magnitude higher than that of inshore sponges (Whalan et al 2007). This, combined with evidence of some localised recruitment for R. odorabile (Whalan et al 2008b), supports a role for variation in larval supply and recruitment affecting the abundance reported here.…”

“…Interestingly, some species such as the Great Barrier Reef sponge Rhopaloeides odorabile (Whalan et al . ) or the Mediterranean sponge Chondrosia reniformis (Lazoski et al . ) are genetically homogeneous over a scale of tens to thousands of kilometres suggesting that the larvae are capable of living much longer than previously thought.…”

“…Bell et al 2014). Interestingly, some species such as the Great Barrier Reef sponge Rhopaloeides odorabile (Whalan et al 2008) or the Mediterranean sponge Chondrosia reniformis (Lazoski et al 2001) are genetically homogeneous over a scale of tens to thousands of kilometres suggesting that the larvae are capable of living much longer than previously thought. In these cases, it is possible the larvae use dissolved organic carbon for energy as shown by Jaeckle (1995) to reach such great distances.…”
