Coral bleaching is the detrimental expulsion of algal symbionts from their cnidarian hosts, and predominantly occurs when corals are exposed to thermal stress. The incidence severity often spatially heterogeneous within reef-scales (<1 km), therefore not predictable using conventional remote sensing products. Here, we systematically assess relationship between in situ measurements 20 environmental variables, along with seven remotely sensed SST stress metrics, 81 observed events at coral...
Peer reviewed research is paramount to the advancement of science. Ideally, peer review process an unbiased, fair assessment scientific merit and credibility a study; however, well-documented biases arise in all methods review. Systemic have been shown directly impact outcomes review, yet little known about downstream impacts unprofessional reviewer comments that are shared with authors.In anonymous survey international participants science, technology, engineering, mathematics (STEM)...
Success and impact metrics in science are based on a system that perpetuates sexist racist “rewards” by prioritizing citations factors. These flawed biased against already marginalized groups fail to accurately capture the breadth of individuals’ meaningful scientific impacts. We advocate shifting this outdated value advance through principles justice, equity, diversity, inclusion. outline pathways for paradigm shift values multidimensional mentorship promoting mentee well-being. actions...
There is a long history of examining the impacts nutrient pollution and pH on coral reefs. However, little known about how these two stressors interact influence reef ecosystem functioning. Using six-week addition experiment, we measured impact elevated nitrate (NO − 3 ) phosphate (PO 3− 4 net community calcification (NCC) production (NCP) rates individual taxa combined communities. Our study had four major outcomes: (i) NCC declined in response to all substrate types, (ii) mixed switched...
Spatial and temporal environmental variability are important drivers of ecological processes at all scales. As new tools allow the in situ exploration individual responses to fluctuations, ecologically meaningful ways characterizing organism scales needed. We investigated fine-scale spatial heterogeneity high-frequency temperature, dissolved oxygen concentration, pH experienced by benthic organisms a shallow coastal coral reef. used spatio-temporal sampling design, consisting 21 short-term...
Coral reefs experience numerous environmental gradients affecting organismal physiology and species biodiversity, which ultimately impact community metabolism. This study shows that submarine groundwater discharge (SGD), a common natural gradient in coastal ecosystems associated with decreasing temperatures, salinity pH increasing nutrients, has both direct indirect effects on coral reef metabolism by altering individual growth rates composition. Our data revealed SGD exposure hindered the...

Abstract A substantial body of research now exists demonstrating sensitivities marine organisms to ocean acidification (OA) in laboratory settings. However, corresponding situ observations species or ecosystem changes that can be unequivocally attributed anthropogenic OA are limited. Challenges remain detecting and attributing effects nature, part because multiple environmental co-occurring with OA, all which have the potential influence responses. Furthermore, change pH since industrial...
Ocean acidification (OA) projections are primarily based on open ocean environments, despite the ecological importance of coastal systems in which carbonate dynamics fundamentally different. Using temperate tide pools as a natural laboratory, we quantified relative contribution community composition, ecosystem metabolism, and physical attributes to spatiotemporal variability chemistry. We found that biological processes were primary drivers local pH conditions. Specifically, non-encrusting...
Invasive lionfish are assumed to significantly affect Caribbean reef fish communities. However, evidence of effects on native fishes is based uncontrolled observational studies or small-scale, unrepresentative experiments, with findings ranging from no effect large prey density and richness. Moreover, whether populations communities at larger, management-relevant scales unknown. The purpose this study was assess the coral in a natural complex system. We quantified density, richness,...
Abstract Siliceous sponges have survived pre-historical mass extinction events caused by ocean acidification and recent studies suggest that siliceous will continue to resist predicted increases in acidity. In this study, we monitored silica biomineralization the Hawaiian sponge Mycale grandis under pCO2 sea surface temperature scenarios for 2100. Our goal was determine if spicule enhanced or repressed thermal stress monitoring uptake rates during short-term (48 h) experiments comparing...
Abstract Submarine groundwater discharge (SGD) is an important source of nutrients to many coastal reefs, yet there little information on how SGD impacts key coral reef processes. Here, we investigated the effect growth and bioerosion rates from Porites lobata nubbins blocks calcium carbonate (CaCO 3 ) two flats in Maunalua Bay, O'ahu. Over a 6‐month (coral nubbins) yearlong blocks) deployment period, combined multiple metrics (buoyant weight, surface area, linear extension) with suite...
Coral reefs experience numerous natural and anthropogenic environmental gradients that alter biophysical conditions affect biodiversity. While many studies have focused on drivers of reef biodiversity using traditional diversity metrics (e.g., species richness, diversity, evenness), less is known about how variability may influence functional diversity. In this study, we tested the impact submarine groundwater discharge (SGD) taxonomic in Mo‘orea, French Polynesia. SGD expulsion terrestrial...
Coral reefs are highly productive ecosystems where bacterioplankton play a critical role in recycling dissolved compounds, enabling corals to thrive oligotrophic waters. Reefs worldwide exhibit trends of declining coral cover with concomitant increases macroalgae. This project seeks understand how these may alter microbial carbon and nutrient supporting the resilience climate change. Decadal data from Moorea Reef Long Term Ecological Research program (MCR LTER) show that have suffered...
Abstract. Climate change threatens both the accretion and erosion processes that sustain coral reefs. Secondary calcification, bioerosion, reef dissolution are integral to structural complexity long-term persistence of reefs, yet these have received less research attention than by corals. In this study, we use climate scenarios from RCP 8.5 examine combined effects rising ocean acidity sea surface temperature (SST) on secondary calcification rates a natural rubble community using...
Abstract Dissolved organic matter (DOM) composition influences microbial community metabolism and benthic primary producers are a source of DOM in coral reefs. As reef communities change, part due to nutrient pollution, understanding impacts on processes requires knowledge sources composition. We conducted multi‐week mesocosm experiment dosing four constituents with three levels nitrate phosphate contrast exudate quantify the effects enrichment release. Moderate enhanced bulk dissolved...
Submarine groundwater discharge (SGD) influences near-shore coral reef ecosystems worldwide. SGD biogeochemistry is distinct, typically with higher nutrients, lower pH, cooler temperature and salinity than receiving waters. can also be a conduit for anthropogenic nutrients other pollutants. Using Bayesian structural equation modelling, we investigate pathways feedbacks by which ecosystem metabolism at two Hawai'i sites distinct aquifer chemistry. The thermal biogeochemical environment...
Abstract Work on marine biofilms has primarily focused host-associated habitats for their roles in larval recruitment and disease dynamics; little is known about the factors regulating composition of reef environmental biofilms. To contrast succession, benthic communities nutrients structuring biofilms, we surveyed bacteria through a six-week succession aquaria containing macroalgae, coral, or sand factorially crossed with three levels continuous nutrient enrichment. Our findings demonstrate...
