In recent decades, coral reef ecosystems have declined to the extent that reefs are now threatened globally. While many water quality parameters been proposed contribute declines, little evidence exists conclusively linking specific with increased disease prevalence in situ. Here we report from situ health surveys confirming chronic exposure dredging-associated sediment plumes significantly increase of white syndromes, a devastating group globally important diseases. Coral were conducted...
Background Globally, coral bleaching has been responsible for a significant decline in both cover and diversity over the past two decades. During summer of 2010–11, anomalous large-scale ocean warming induced unprecedented levels accompanied by substantial storminess across more than 12° latitude 1200 kilometers coastline Western Australia (WA). Methodology/Principal Findings Extreme La-Niña conditions caused extensive waters drove considerable cyclonic activity WA from October 2010 to May...
Abstract There has been rapid uptake of stereo‐video‐based sampling techniques to collect species, abundance and body‐size information on fish assemblages their associated habitats. Stereo‐video methods provide highly accurate estimates body‐size, range area as well a permanent record that can be cross‐checked or resampled for additional data. Due these advantages, diver‐operated stereo‐video (stereo‐DOV) is becoming an increasingly popular alternative underwater visual census. We...
Robust assessments of abundance and diversity are essential components research programs aimed at detecting changes in marine fish assemblages through space time. This study examined the comparability Underwater Visual Census (UVC), Diver Operated stereo‐Video (Stereo‐DOV) datasets collected across a wide latitudinal range (15°) on coral reefs temperate rocky shores. There were some differences between methods with regards to both species richness abundance, UVC consistently recording higher...
Abstract Aim To describe, model and assess the relative importance of environmental climatic factors likely influencing regional distribution coral cover assemblages with contrasting life histories susceptibilities to bleaching. Location We compiled first comprehensive empirical dataset for communities in south‐eastern Indian Ocean ( SEIO ), incorporating information from 392 sites along western coast Australia offshore atolls/islands across ~19° latitude. Methods assessed hard community...
Abstract Aim Predictions for the future of coral reefs are largely based on thermal exposure and poorly account potential geographic variation in biological sensitivity to stress. Without accounting complex responses, simple climate models associated predictions may lead poor estimates survival policies that fail identify implement most appropriate interventions. To begin filling this gap, we evaluated a number attributes taxa communities predicted influence resistance stress over large...
Complex histories of chronic and acute sea surface temperature (SST) stresses are expected to trigger taxon- location-specific responses that will ultimately lead novel coral communities. The 2016 El Niño-Southern Oscillation provided an opportunity examine large-scale recent environmental on emerging patterns in 226 communities distributed across 12 countries from East Africa Fiji. Six main were identified largely varied a gradient Acropora massive Porites dominance. Bleaching intensity was...
Monitoring changes in coral cover and composition through space time can provide insights to reef health assist the focus of management conservation efforts. We used a meta-analytical approach assess data across latitudes 10–35°S along west Australian coast, including 25 years from Ningaloo region. Current estimates ranged between 3 44% habitats. Coral communities northern regions were dominated by corals families Acroporidae Poritidae, which became less common at higher latitudes. At Reef...
Context The sustainable supply of fish in the face climate change and other drivers is a policy priority for Pacific nations. Creel market surveys are increasingly used to document catches but this information has not been aggregated at regional scale. Aims In paper we provide comprehensive standardized list marine foodfishes 22 Island Countries Territories enable comparative analyses improved national surveys. Methods National lists teleost caught food were cleaned errors current valid...
Technological advancements in remote sensing and GIS have improved natural resource managers' abilities to monitor large-scale disturbances. In a time where many processes are heading towards automation, this study has regressed simple techniques bridge gap found the advancement of technology. The near-daily monitoring dredge plume extent is common practice using Moderate Resolution Imaging Spectroradiometer (MODIS) imagery associated algorithms predict total suspended solids (TSS)...
Information for monitoring marine communities is increasingly collected using digital imagery and there a need to understand how data different methods compare. This study investigated the comparability of benthic by downward facing diver operated stereo-video (DOV) with forward stereo-DOV typically used in fish surveys. Data sets were both from same transect along which benthos visible each method was identified taxonomy, growth form or substratum class. Analyses indicated that 77% taxa...

Abstract Fluctuations in marine populations often relate to the supply of recruits by oceanic currents. Variation these currents is typically driven large‐scale changes climate, particular ENSO (El Nino Southern Oscillation). The dependence on climatic may, however, be modified early life history traits taxa. Based eight years annual surveys, along 150 km coastline, we examined how influenced abundance juvenile fish, coral spat, and canopy‐forming macroalgae. We then investigated what make...
Coral reefs have been heavily affected by elevated sea-surface temperature (SST) and coral bleaching since the late 1980s; however, until recently coastal of north-western Australia relatively unaffected compared to Timor Sea eastern Australian reefs. We compare SST time series with changes in cover spanning a period up 36 years describe temporal spatial variability associated mortality throughout Pilbara–Ningaloo region. Declines ranged from 12.5 51.3%, relative declines ranging 38 92%....
Abstract Before‐After‐Control‐Impact (BACI) designs are widespread in environmental science, however their implicitly hierarchical nature complicates the evaluation of statistical power. Here, we describe epower , an r package for assessing power BACI designs. The uses Bayesian methods via ‐package INLA to fit appropriate model user supplied pilot survey data. A posterior sample is then used build a Monte Carlo simulation test specifically Before/After × Control/Impact interaction term...
