Coral bleaching, during which corals lose their symbiotic dinoflagellates, typically corresponds with periods of intense heat stress, and appears to be increasing in frequency geographic extent as the climate warms. A fundamental question coral reef ecology is whether chronic local stress reduces resistance resilience from episodic such or alternatively promotes acclimatization, potentially resilience. Here we show that following a major bleaching event, Montastraea faveolata growth rates at...
Coral bleaching is the breakdown of symbiosis between coral animal hosts and their dinoflagellate algae symbionts in response to environmental stress. On large spatial scales, heat stress most common factor causing bleaching, which predicted increase frequency severity as climate warms. There evidence that temperature threshold at occurs varies with local conditions background conditions. We investigated influence past variability on susceptibility using natural gradient peak Gilbert...
Microplastics (less than 5 mm) are a recognized threat to aquatic food webs because they ingested at multiple trophic levels and may bioaccumulate. In urban coastal environments, high densities of microplastics disrupt nutritional intake. However, behavioural dynamics consequences microparticle ingestion still poorly understood. As filter or suspension feeders, benthic marine invertebrates vulnerable microplastic ingestion. We explored by the temperate coral Astrangia poculata . detected an...
Abstract Previous studies have estimated that coastal cliffs exist on about 80% of the global shoreline, but not been validated a scale. This study uses two approaches to capture information worldwide existence and erosion cliffs: detailed literature survey imagery search, GIS‐based mapping analysis. The review show in 93% combined recognized independent states non‐independent regions (total 213 geographic units). Additionally, cliff retreat rates quantified at least one location within 33%...
Abstract Coral bleaching, during which corals lose their symbiotic dinoflagellates, appears to be increasing in frequency and geographic extent, is typically associated with abnormally high water temperatures solar irradiance. A key question coral reef ecology whether local stressors reduce the thermal tolerance threshold, leading increased bleaching incidence. Using tree‐ring techniques, we produced master chronologies of growth rates dominant builder, massive Montastraea faveolata corals,...

The Congo Basin is home to the world’s largest tropical peatland complex storing 29 PgC across 16.7 million ha, which poses a major unconstrained source of global wetland CH4. Key controls over their spatio-temporal variability remain unclear, limiting our ability assess responses future environmental change. Here, we present first time series in situ measurements from four intensive locations covering peat, seasonally flooded and terra firma forest ecosystems. Measurements were...
Abstract Frequent occurrences of coral bleaching and associated mortality over recent decades have raised concerns about the survival reefs in a warming planet. The El Niño-influenced central Gilbert Islands Republic Kiribati, which experience years with prolonged heat stress more frequently than 99% world’s reefs, may serve as natural model for community response to frequent stress. Here we use nine survey data (2004–2012) suite remote sensing variables from sites along gradients climate...
Abstract Equatorial Pacific ocean‐atmosphere interactions affect climate globally, and a key component of the coupled system is Walker Circulation, which driven by sea surface temperature (SST) gradients across equatorial Pacific. There conflicting evidence as to whether SST gradient Circulation have strengthened or weakened over late twentieth century. We present new records salinity (SSS) spanning 1959–2010 based on paired measurements Sr/Ca δ 18 O in massive Porites coral from Butaritari...
Coral reefs thrive and provide maximal ecosystem services when they support a multi-level trophic structure grow in favorable water quality conditions that include high light levels, rapid flow, low nutrient levels. Poor other anthropogenic stressors have caused coral mortality recent decades, leading to downgrading the loss of biological complexity on many reefs. Solutions reverse causes remain elusive, part because efforts restore are often attempted same diminished first place. Arks,...
Abstract Per‐ and polyfluoroalkyl substances (PFAS) are a large group of synthetic compounds that have emerged as chemicals concern in drinking water groundwater. Typically, such waters treated to remove PFAS by passing the through bed sorbent material (e.g., activated carbon anion exchange resins [AIX]). However, efficacy these sorbents varies depending on types concentrations PFAS, addition quality conditions organic matter content conductivity (ionic strength). The choice effectively...

Abstract Global surface temperatures during the twentieth century are characterized by multidecadal periods of accelerated or reduced warming, which thought to be driven Pacific decadal variability, specifically changes in trade‐wind strength. However, relationship between strength and global warming remains poorly constrained due scarcity instrumental wind observations. Previous work has shown that corals growing at Tarawa Atoll (1.3°N, 173°E) incorporate dissolved Mn flushed from lagoon...
Within boulder forming corals, fixation of dissolved inorganic carbon is performed by symbiotic dinoflagellates within the coral tissue and, to a lesser extent, endolithic algae skeleton. Endolithic produce distinctive green bands in skeleton, and their origin may be related periods bleaching due complete loss dinoflagellate symbionts or "paling" which symbiont populations are patchily reduced tissue. Stable isotopes were analyzed skeletons across known event 12 blooms determine whether...
Abstract Coral bleaching caused by heat stress (warm water) will arguably be the greatest driver of coral reef loss in coming decades. Understanding how corals have adapted to distinct oceanographic regimes on multiple scales can provide insight into future tolerance and persistence, information critical directed intervention or targeted protections. The northern Line Islands span a gradient across latitudes, with seawater becoming warmer, fresher, more oligotrophic, saturated aragonite away...

The model was calibrated/validated based SCI SCZ observations using digital elevation models (DEMs), modeled nearshore wave climate, as well...
