“…In addition, interactions with fishing vessels and other boats constitute an important cause of injury-induced mortality, especially for coastal air-breathing marine fauna such as marine mammals and reptiles (Shimada et al 2017). In Moreton Bay (Queensland, Australia), for instance, the most commonly known causes of mortality for dugongs (Dugong dugon) were vessel strikes, trauma, and netting, and sea turtles are similarly impacted by boat strikes and discarded fishing gear (Lanyon 2019).…”

Marine biodiversity plays an important role in providing the ecosystem functions and services which humans derive from the oceans. Understanding how this provisioning will change in the Anthropocene requires knowledge of marine biodiversity patterns. Here, we review the status of marine species diversity in space and time. Knowledge of marine species diversity is incomplete, with only 11% of species described. Nonetheless, marine biodiversity is clearly under threat, and habitat destruction and overexploitation represent the greatest stressors to threatened marine species. Claims that global marine extinction rates are within historical backgrounds and lower than on land may be inaccurate, as fewer marine species have been assessed for extinction risk. Moreover, extinctions and declines in species richness at any spatial scale may inadequately reflect marine diversity trends. Marine local-scale species richness is seemingly not decreasing through time. There are, however, directional changes in species composition at local scales. These

“…The bay is large (~1500 km 2 ) and 125 km long, with a broad (35 km) opening at its widest west–east axis. This lagoon-like bay is surrounded by four large continental sand islands—Bribie, Moreton, North Stradbroke, and South Stradbroke [10]. The Bay has three openings to the Pacific Ocean.…”

“…The greater Moreton Bay catchment comprises 21,200 km 2 of land, with four main rivers that drain into Moreton Bay: the Caboolture, Pine, Brisbane, Logan-Albert, and Pimpama Rivers. The river outflow includes effluent from riparian agriculture, treated sewage, and residential and industrial discharges, in addition to urban litter and pollution [10].…”

“…The Bay provides aquaculture, industrial, residential, and shipping services, making it vulnerable to environmental stresses. Being subtropical, Moreton Bay supports a diverse community of marine megafauna such as fish, migratory whales, corals, and subtropical species including sea turtles, dugongs, and Australian humpback dolphins [10]. The Bay also provides a variety of habitats for wildlife including extensive wetlands, shallow sandbanks, mudflats, mangrove forests, coral reefs, seagrass meadows, and myriad creeks, brooks, and rivulets [10].…”

Rapid urban expansion and increased human activities have led to the progressive deterioration of many marine ecosystems. The diverse microbial communities that inhabit these ecosystems are believed to influence large-scale geochemical processes and, as such, analyzing their composition and functional metabolism can be a means to assessing an ecosystem’s resilience to physical and chemical perturbations, or at the very least provide baseline information and insight into future research needs. Here we show the utilization of organic and inorganic contaminant screening coupled with metabolomics and bacterial 16S rRNA gene sequencing to assess the microbial community structure of marine sediments and their functional metabolic output. The sediments collected from Moreton Bay (Queensland, Australia) contained low levels of organic and inorganic contaminants, typically below guideline levels. The sequencing dataset suggest that sulfur and nitrite reduction, dehalogenation, ammonia oxidation, and xylan degradation were the major metabolic functions. The community metabolites suggest a level of functional homogeneity down the 40-cm core depth sampled, with sediment habitat identified as a significant driver for metabolic differences. The communities present in river and sandy channel samples were found to be the most active, with the river habitats likely to be dominated by photoheterotrophs that utilized carbohydrates, fatty acids and alcohols as well as reduce nitrates to release atmospheric nitrogen and oxidize sulfur. Bioturbated mud habitats showed overlapping faunal activity between riverine and sandy ecosystems. Nitrogen-fixing bacteria and lignin-degrading bacteria were most abundant in the sandy channel and bioturbated mud, respectively. The use of omics-based approaches provide greater insight into the functional metabolism of these impacted habitats, extending beyond discrete monitoring to encompassing whole community profiling that represents true phenotypical outputs. Ongoing omics-based monitoring that focuses on more targeted pathway analyses is recommended in order to quantify the flux changes within these systems and establish variations from these baseline measurements.
