Whole Genome Sequencing Reveals Genetic Differences Between Symbiodiniaceae Populations Among Reproductively and Geographically Isolated Colonies in Western Australia.

Significant genetic differentiation between Symbiodiniaceae populations in coral hosts can be induced by a range of factors including geography, latitude, depth, temperature and light utilisation. The conventional method of measuring Symbiodiniaceae diversity involving the ITS2 region of rDNA has several limitations, stemming from insufficient genetic resolution and the multi-copy nature of the marker. This could be improved by using higher throughput whole genome sequencing to identify fine-scale population genetic differences and provide new insight into factors influencing coral-Symbiodiniaceae associations.

Testing sea urchin and green sea turtle consumption of the allelopathic macroalga .

is a partially calcified macroalga that hampers coral recruitment, growth, and recovery via the excretion of allelopathic secondary metabolites. Herbivorous fishes are not major consumers of spp. and there is a need to understand feeding preferences for in other macroherbivores, like sea urchins and green sea turtles that could act as potential controlling agents.

Incidence of shark-inflicted bite injuries on Australian snubfin () and Australian humpback () dolphins in coastal waters off east Queensland, Australia.

The ecology and evolution of prey populations are influenced by predation and predation risk. Our understanding of predator-prey relationships between sharks and dolphins is incomplete due to the difficulties in observing predatory events directly. Shark-inflicted wounds are often seen on dolphin bodies, which can provide an indirect measure of predation pressure.
