The influence of multiple stressors on the spatial distribution of corals

People and Nature, EarlyView.
Abstract Coral reef ecosystems are widely threatened by global change, yet the cumulative impacts of multiple interacting stressors remain difficult to quantify over space and time. We evaluate how long‐term artisanal fishing effort, blast fishing, human population density and marine protected areas (MPAs) interact with biophysical and seascape ...

Breaking down seagrass fragmentation in a marine heatwave impacted World Heritage Area

Remote Sensing in Ecology and Conservation, EarlyView.
Habitat fragmentation can exacerbate the impacts of habitat loss but is rarely quantified in marine environments. Using satellite‐derived habitat maps, we identify widespread seagrass fragmentation following a marine heatwave that contributed to a dramatic shift in seascape structure in the Shark Bay World Heritage Area.

Detection of Coral Reef Bleaching by Multitemporal Sentinel-2 Data Using the PU-Bagging Algorithm: A Feasibility Study at Lizard Island

Remote Sensing
Coral reef bleaching events have become more frequent all over the world and pose a serious threat to coral reef ecosystems. Therefore, there is an urgent need for better detection of coral reef bleaching in a time- and cost-saving manner.

Coral Bleaching Susceptibility Is Predictive of Subsequent Mortality Within but Not Between Coral Species

Frontiers in Ecology and Evolution, 2020
Marine heat waves instigated by anthropogenic climate change are causing increasingly frequent and severe coral bleaching events that often lead to widespread coral mortality.

Evaluating land–sea linkages using land cover change and coral reef monitoring data: A case study from northeastern Puerto Rico

Remote Sensing in Ecology and Conservation, EarlyView.
Land cover change that leads to increased nutrient and sediment runoff is an important driver of change in coral reef ecosystems. In this study, we combined satellite remote sensing and field monitoring to assess concomitant changes in watershed land cover and coral cover in northeastern Puerto Rico in 2000–2015.

Integrating equity-focused planning into coral bleaching management

npj Ocean Sustainability, 2023
Coral bleaching, associated with warm water temperatures of the oceans, represents the most significant threat to coral reef ecosystems and coastal communities regarding climate change. Coral bleaching prediction models have emerged as essential tools in

Bacterial Communities Vary from Different Scleractinian Coral Species and between Bleached and Non-Bleached Corals

Microbiology Spectrum, 2023
Accumulating evidence indicates that coral-associated bacteria play an important role in the health of holobionts. However, the variability of the symbiotic bacterial community structure among coral species with different coral health statuses remains largely unknown.

Blue‐Prints for Ocean Governance: Analyzing Resource Sustainability in International Blue Economic Frameworks

Sustainable Development, EarlyView.
ABSTRACT Championed as a pathway for sustainable growth, the “blue economy” (BE) has garnered increasing interest in recent decades. International organizations like the World Bank and the Organization for Economic Cooperation and Development (OECD) increasingly point to marine resources and activities as a “new frontier” for economic growth ...

Half a century of echinoid population decline in the northern Gulf of Aqaba, Red Sea

Journal of Animal Ecology, EarlyView.
Multi‐decadal monitoring in the Gulf of Aqaba, northern Red Sea, reveals severe (>90%) declines of key echinoid grazers. These declines signify a collapse of crucial herbivory functions underpinning coral reef resilience. Results implicate accelerating anthropogenic stress as a principal driver, emphasizing the urgent need for sustained, species ...

Widespread loss of Caribbean acroporid corals was underway before coral bleaching and disease outbreaks

Science Advances, 2020
Endangered staghorn and elkhorn corals began disappearing from Caribbean reefs decades before climate change impacts. The mass mortality of acroporid corals has transformed Caribbean reefs from coral- to macroalgal-dominated habitats since systematic ...
