Modern biodiversity monitoring programs are designed to provide rapid assessments of trends in the abundance and distribution of keystone taxa and timely scientific insights for decision‐making. An important consideration when delivering this information to stakeholders is the quantification of uncertainty, which determines the robustness of detecting changes across habitats and regions. In coral reef science, sparse and fragm...
Substantial impacts from the 2024 summer reverse five years of coral cover gains on the Great Barrier ReefNARA Subscribed
Anthropogenic climate change is fuelling repeated marine heatwaves and has triggered the fourth global mass coral bleaching event in 2023–2025, causing widespread coral mortality worldwide. Here, we document the impacts of this event on the Great Barrier Reef (GBR), where heat accumulation peaked in February–March 2024 and caused mass coral bleaching for the seventh time since 1998. We use data from the Australian Institute of...
Feeding preferences and growth in herbivorous juvenile crown-of-thorns sea stars (Acanthaster cf. solaris)NARA Subscribed
Crown-of-thorns sea stars (CoTS; Acanthaster spp.) are among the most prominent corallivorous invertebrates, contributing greatly to the plight of tropical coral reefs in the Anthropocene. Much of the success of CoTS, and their propensity to undergo major population irruptions, are likely tied to inherent biological traits. Juvenile CoTS feed on coralline algae prior to their ontogenetic switch to corallivory, but their feedin...
Regional‐scale disturbances drive long‐term decline of inshore coral reef fish assemblages in the Great Barrier Reef Marine ParkNARA Subscribed
Anthropogenic pressure is increasing the variety and frequency of environmental disturbance events, limiting recovery and leading to long‐term declines in wild plant and animal populations. Coral reefs and associated fish assemblages are inherently dynamic due to their susceptibility to a host of disturbances, but regional‐scale nuances in the drivers of long‐term change frequently remain poorly resolved. Here, we examine the...
Feeding rates and carbon and nitrogen partitioning in crown-of-thorns sea star larvae (Acanthaster cf. solaris) during developmentNARA Subscribed
Crown-of-thorns sea star (CoTS; Acanthaste r cf. solaris ) outbreaks are a significant cause of coral decline. Enhanced food supply for the larvae via eutrophication is implicated as a cause of outbreaks, yet larval feeding ecology is poorly understood. In this study, feeding experiments were carried out at two algal food concentrations of 1000 cells mL −1 (~ 1.52 µg chl a L −1 ) and 3000 cells mL −1 (~ 4.56 µg chl a L −1 ) ac...
The exosome: a review of current therapeutic roles and capabilities in human reproductionNARA Subscribed
Exosomes are nano-vesicles (30–150 nm) which may be useful as therapeutic delivery vehicles and as diagnostic biomarkers. Exosomes are produced naturally within the human body and therefore are not prone to immunogenicity effects which would otherwise destroy unelicited foreign bodies. Clinically, they have been regarded as ideal candidates for applications relating to biomarker developments for the early detection of differen...
Prolonging survival in good health is a fundamental societal goal. However, the leading determinants of disability-free survival in healthy older people have not been well established. Data from ASPREE, a bi-national placebo-controlled trial of aspirin with 4.7 years median follow-up, was analysed. At enrolment, participants were healthy and without prior cardiovascular events, dementia or persistent physical disability. Disab...
Strong population-by-habitat interactions across environmental gradients arise from genetic adaptation or acclimatization and represents phenotypic variation required for populations to respond to changing environmental conditions. As such, patterns of adaptation and acclimatization of reef-building corals are integral to predictions of the future of coral reefs under climate warming. The common brooding coral, Pocillopora dam...
Delayed coral recovery in a warming oceanNARA Subscribed
Climate change threatens coral reefs across the world. Intense bleaching has caused dramatic coral mortality in many tropical regions in recent decades, but less obvious chronic effects of temperature and other stressors can be equally threatening to the long‐term persistence of diverse coral‐dominated reef systems. Coral reefs persist if coral recovery rates equal or exceed average rates of mortality. While mortality from acu...
Behavioral responses of Australian fur seals ( Arctocephalus pusillus doriferus ) to environmental variationsNARA Subscribed
Observing how pinnipeds respond to variations in climatic and oceanographic conditions informs marine managers on factors that could limit their range, foraging ability and breeding success. Here, we examine how Australian fur seals ( Arctocephalus pusillus doriferus ) at Seal Rocks, Victoria, Australia, responded to normal climatic conditions from August 2009 to January 2010, which included their Austral spring‐summer breedin...
