Inter-reef Halimeda algal habitats within the Great Barrier Reef support a distinct biotic community and high biodiversity.

Tropical marine biodiversity studies have been biased towards more accessible coastal habitats and shallow coral reefs, while deeper inter-reef habitats are less studied due to different survey challenges. One such inter-reef habitat is the 'bioherms' dominated by the calcareous Halimeda macroalgae. In the northern section of Australia's Great Barrier Reef, Halimeda algal bioherms occupy >6,000 km of the inter-reef seabed, more than twice the area of adjacent shallow coral reefs.

SSNdesign-An R package for pseudo-Bayesian optimal and adaptive sampling designs on stream networks.

Streams and rivers are biodiverse and provide valuable ecosystem services. Maintaining these ecosystems is an important task, so organisations often monitor the status and trends in stream condition and biodiversity using field sampling and, more recently, autonomous in-situ sensors. However, data collection is often costly, so effective and efficient survey designs are crucial to maximise information while minimising costs.

Giant coral reef fishes display markedly different susceptibility to night spearfishing.

The humphead wrasse () and bumphead parrotfish () are two of the largest, most iconic fishes of Indo-Pacific coral reefs. Both species form prized components of subsistence and commercial fisheries and are vulnerable to overfishing. is listed as Endangered and as Vulnerable on the IUCN Red List of Threatened Species.

Using virtual reality to estimate aesthetic values of coral reefs.

Aesthetic value, or beauty, is important to the relationship between humans and natural environments and is, therefore, a fundamental socio-economic attribute of conservation alongside other ecosystem services. However, beauty is difficult to quantify and is not estimated well using traditional approaches to monitoring coral-reef aesthetics. To improve the estimation of ecosystem aesthetic values, we developed and implemented a novel framework used to quantify features of coral-reef aesthetics based on people's perceptions of beauty.
