Marine reserves contribute half of the larval supply to a coral reef fishery Open
Marine reserves deliver impressive increases in the abundance and size of exploited species on protected reefs, but larval dispersal makes it difficult to estimate their wider benefits. Australia’s Great Barrier Reef (GBR) contains an exte…
Calcification trends in long-lived corals across the Indo-Pacific during the industrial era Open
Skeletal cores from massive, long-lived coral colonies provide a unique approach to investigating the chronic effects of climate change on coral calcification across decadal to centennial timescales. Here, we show an overall decline in cal…
Dispersal patterns of sandfish (Holothuria scabra) larvae in Manus Province, Papua New Guinea Open
In many tropical nations, coastal communities seek to manage their sea cucumber fisheries by establishing locally managed marine areas on their traditional fishing grounds. These managed areas can protect spawning stocks, however the exten…

Symbiodiniaceae diversity varies by host and environment across thermally distinct reefs Open
Endosymbiotic dinoflagellates (Symbiodiniaceae) influence coral thermal tolerance at both local and regional scales. In isolation, the effects of host genetics, environment, and thermal disturbances on symbiont communities are well underst…

Ageing of juvenile coral grouper ( <i>Plectropomus maculatus</i> ) reveals year-round spawning and recruitment: implications for seasonal closures Open
Temporal patterns in spawning and juvenile recruitment can have major effects on population size and the demographic structure of coral reef fishes. For harvested species, these patterns are crucial in determining stock size and optimizing…
Genetic parentage analysis as a tool for measuring larval connectivity in a network of marine reserves Open
Networks of no‐take marine reserves are widely advocated as a means to conserve biodiversity and manage coastal fisheries. Reserves not only deliver rapid and long‐term benefits within their boundaries, they also provide a broader framewor…
Differential bleaching susceptibility among coral taxa and colony sizes, relative to bleaching severity across Australia's Great Barrier Reef and Coral Sea Marine Parks Open
Climate-induced coral bleaching represents the foremost threat to coral assemblages globally, however bleaching susceptibility varies among and within coral taxa. We compared bleaching susceptibility among 10 coral morpho-taxa and two colo…

Macroalgae exhibit diverse responses to human disturbances on coral reefs Open
Scientists and managers rely on indicator taxa such as coral and macroalgal cover to evaluate the effects of human disturbance on coral reefs, often assuming a universally positive relationship between local human disturbance and macroalga…

The Fisheries Co-Management Guidebook Open
Small-scale fisheries account for 40% of global fish catch and employ more than 90% of the world’s fishers, defining the livelihoods, nutrition, and culture of a substantial and diverse segment of humankind. In recent decades collaborative…
The effects of marine heatwaves on acute heat tolerance in corals Open
Scleractinian coral populations are increasingly exposed to conditions above their upper thermal limits due to marine heatwaves, contributing to global declines of coral reef ecosystem health. However, historic mass bleaching events indica…

The 2014-17 Global Coral Bleaching Event: The Most Severe and Widespread Coral Reef Destruction Open
Ocean warming is increasing the incidence, scale, and severity of global-scale coral bleaching and mortality, culminating in the third global coral bleaching event that occurred during record marine heatwaves of 2014-2017. While local effe…
Experimental considerations of acute heat stress assays to quantify coral thermal tolerance Open
Thermal tolerance is variable in corals, yet intrinsic and extrinsic drivers of tolerance are not well understood. Understanding the distribution and abundance of heat tolerant corals across seascapes is imperative for predicting responses…
