Summary: The response-and-effect framework is a trait-based approach that aims to analyze the mechanistic links between ecosystem disturbances, species' traits, and ecosystem processes. A review of coral reef fish traits literature shows a focus on linking response traits to disturbances, with fewer studies connecting effect traits to ecosystem processes. Size and diet of fish are identified as common traits in the literature, crucial for understanding both disturbance and process in ecosystems.

Summary: Tourism-led stewardship projects in the Great Barrier Reef have implemented coral propagation and out-planting practices to improve ecosystem function. Benthic surveys conducted over a 24-month period showed significant increases in hard coral cover at some out-planting sites, particularly for commonly out-planted genera. Despite variations in coral community responses, this tourism-led approach has demonstrated potential for increasing hard coral cover through coral propagation.

Summary: Coral reefs, as the most spectacular underwater creation, play crucial roles in ecosystem functioning and coastal community livelihood. However, marine debris poses a severe threat to these sensitive habitats and their associated organisms. Despite scientific attention, data regarding the sources, abundance, distribution, and potential consequences of marine debris on reef ecosystems are lacking. This review aims to provide an overview of the current status and impacts of marine debris, with emphasis on sources, distribution, affected species, and management strategies, as well as highlighting the adhesion mechanisms and diseases caused by microplastics to coral polyps.

Summary: The study shows that broader and shallower coral restoration projects are most effective in reducing wave-driven flooding, such as those on the upper fore reef and between the reef flat and shoreline, compared to deeper locations on the fore reef or at the reef crest. It suggests that planting more physically robust coral species in shallower and more energetic locations can increase the coastal hazard risk reduction potential of reef restoration.

Summary: The 2020 marine heatwave in the Great Barrier Reef and Coral Sea caused mass coral bleaching, with sea surface temperature anomalies exceeding +2 degrees C across broad regions. While the model predictions generally agreed with observations in the first week, it failed to capture the development phase and end of the heatwave. Subseasonal variability due to weather systems affected the accuracy of predicting the event's duration and intensity.

Summary: The degradation of shallow ecosystems has led to a need to study and understand the biodiversity and functioning of Mesophotic Ecosystems. However, most research has been limited to tropical regions and focused on species, neglecting other important aspects of biodiversity. By studying a subtropical island in the Atlantic Ocean, we found that fish communities in mesophotic black coral forests (BCFs) differed in functional structure compared to shallow reefs, indicating the importance of specific management and conservation strategies for preserving the unique biodiversity and functionality of mesophotic BCFs.

Summary: Mesophotic coral ecosystems are important, but research on the Great Barrier Reef in Australia is scarce due to reasons such as strict diving regulations, involvement of new researchers, logistics, and cost. Research efforts on these ecosystems are declining, and unless this changes, the knowledge gap between Australian MCEs and other major coral reef regions worldwide will continue to widen. Action is needed to enhance understanding of these ecosystems in Australia.

Summary: Coral propagation through nurseries and out-planting practices has increased globally to improve stakeholder-led stewardship for local reef site health. The tourism industry in the Great Barrier Reef implemented coral propagation after back-to-back bleaching events, overcoming cost-efficiency limitations through the Coral Nurture Program (CNP) partnership model. Success of CNP relies on collaboration between researchers and operators, utilizing complementary expertise and resources for continual improvement. This study examines the CNP activity to evaluate how collective propagation by tourism operators and research validation can enhance site stewardship on the Great Barrier Reef.

Summary: Functional traits can quantify an organism's ecology and predict ecosystem functions based on local communities. However, many functional traits seem to be characterized by availability and implied importance rather than ecological information content. It is necessary to identify functions of interest first and then identify traits as quantifiable proxies.

Summary: By analyzing a global dataset of coral reef benthic cover, the authors found that high macroalgal cover is mainly restricted to the Western Atlantic, and there have also been significant declines in coral cover in the Western Atlantic and Central Pacific since the late 1990s. Understanding the composition and trajectory of coral reef benthic communities is crucial for managing Anthropocene coral reefs, as they are at the forefront of environmental transformation caused by human-induced stressors.

Summary: Different definitions of dominance can greatly influence the understanding of ecosystem shifts, as exemplified by coral reefs. Exclusion of crucial algal groups and variations in categorizing other benthic communities can alter perceptions of coral dominance and the detection of ecosystem phase shifts. Therefore, consensus on the application of dominance concepts is needed to gain a comprehensive understanding of ecosystem changes in aquatic and terrestrial settings.

Summary: Cryptobenthic fishes are abundant and dominant in near reef waters, although the link between pelagic and on-reef processes is not well understood. Through sampling at different depths, the study found clear variation in late-stage larval fish assemblages. Contrary to expectations, late-stage cryptobenthic larvae were found to use large portions of the water column, although their preferred positions could differ among taxa.

Summary: Herbivorous fishes are an important group in coral reef ecosystems and have been extensively studied. However, challenges remain in quantifying patterns versus processes. This article explores how the definition of 'herbivorous reef fishes' hinders the translation between herbivore abundance and herbivory processes. The authors suggest that considering the difficulty of translating patterns in herbivore abundance to herbivory processes and focusing on quantifying herbivory in the epilithic algal matrix (EAM) will be crucial for comprehensive understanding of herbivory on Anthropocene coral reefs.

Summary: Ecosystem recovery from human-induced disturbances is occurring worldwide, but the dynamics and implications for ecosystem management remain unclear. Using coral reefs as a case study, this research found that coral reefs can recover to global average levels within just 2 years, with as few as 11.5 coral recruits per square meter. However, factors such as wave exposure, growth form, and colony density can impact the recovery rates. This study emphasizes the importance of considering natural recovery in management and restoration, and provides insights into the recovery dynamics of high-diversity climate-disturbed ecosystems.

Summary: Sediments on coral reefs are influenced by the amount and movement of sediment in different reservoirs. However, research on reef sediment dynamics and their drivers is limited, especially on clear-water offshore reefs. Using quantification methods, this study examined sediment reservoirs/processes and bio-physical drivers in different reef habitats at Lizard Island on the Great Barrier Reef. The findings showed that a significant amount of suspended sediment passed over the reef, but only a small portion settled. Spatial differences in sediment deposition and accumulation were observed, influenced by wave energy and reef geomorphology. These findings highlight the importance of local hydrodynamic conditions in determining sediment fate on coral reefs.

Summary: Herbivorous fishes and algal turfs are important for the functioning of coral reefs, but their nature on turbid reefs is limited. High turbidity reefs have low herbivorous fish abundance and limited nutritional resources, resulting in reduced productivity compared to clear-water reefs in the Indo-Pacific. This suggests bottom-up nutrient resource limitation due to reduced light levels and sediment-laden conditions on turbid reefs.

Summary: The Barents Sea, as the largest Arctic shelf region, plays a vital role in supporting commercial fisheries. The ecosystem of this region is significantly influenced by both warm Atlantic Water (AW) and cold Arctic Water (ARW), resulting in distinct frontal zones. This study found that copepod populations, particularly herbivorous copepods, were most abundant and productive in the Polar Front, as well as in the eastern frontal zones. The geographic positions of sampling stations, depth, and chlorophyll a concentration were identified as the main factors influencing copepod biomass and production.
