Phthalate esters (PAEs) are known as of phthalic acid, which commonly used plasticizers in the plastic industry. Due to lack chemical bonding with polymer matrix, these compounds easily separated from products and enter environment. To investigate growth concentration PAEs like DBP (Dibutyl phthalate), DEP (Diethyl DMP (Dimethyl DIBP (Diisobutyl TPMBP (tris(2-methylbutyl) phosphate) different water sources, a study January 01, 1976, April 30, 2021, was implemented via global systematic review plus meta-analysis which, 109 articles comprising 4061 samples, 4 types, 27 countries were included.

Coral reefs benefit from reduced land–sea impacts under ocean warming

Nature, Journal Year: 2023, Volume and Issue: 621(7979), P. 536 - 542

Published: Aug. 9, 2023

Coral reef ecosystems are being fundamentally restructured by local human impacts and climate-driven marine heatwaves that trigger mass coral bleaching mortality1. Reducing can increase resistance to recovery from bleaching2. However, resource managers lack clear advice on targeted actions best support reefs under climate change3 sector-based governance means most land- sea-based management efforts remain siloed4. Here we combine surveys of change with a unique 20-year time series land-sea encompassed an unprecedented heatwave in Hawai'i. Reefs increased herbivorous fish populations reduced land-based impacts, such as wastewater pollution urban runoff, had positive cover trajectories predisturbance. These also experienced modest reduction mortality following severe heat stress compared enhanced impacts. Scenario modelling indicated simultaneously reducing results three- sixfold greater probability having high reef-builder four years postdisturbance than if either occurred isolation.

Effects of sediment exposure on corals: a systematic review of experimental studies

Environmental Evidence, Journal Year: 2022, Volume and Issue: 11(1)

Published: Feb. 7, 2022

Management actions that address local-scale stressors on coral reefs can rapidly improve water quality and reef ecosystem condition. In response to managers who need actionable thresholds for coastal runoff dredging, we conducted a systematic review meta-analysis of experimental studies explore the effects sediment corals. We identified exposure levels 'adversely' affect corals while accounting bearing (deposited vs. suspended), life-history stage, species, thus providing empirically based estimates stressor vulnerable reefs.

Corals at the edge of environmental limits: A new conceptual framework to re-define marginal and extreme coral communities

The Science of The Total Environment, Journal Year: 2023, Volume and Issue: 884, P. 163688 - 163688

Published: April 25, 2023

The worldwide decline of coral reefs has renewed interest in communities at the edge environmental limits because they have potential to serve as resilience hotspots and climate change refugia, can provide insights into how might function future ocean conditions. These are often referred marginal or extreme but few definitions exist usage these terms therefore been inconsistent. This creates significant challenges for categorising poorly studied synthesising data across locations. Furthermore, this impedes our understanding persist their lessons reef survival. Here, we propose that related distinct a novel conceptual framework redefine them. Specifically, define extremeness solely based on conditions (i.e., large deviations from optimal mean and/or variance) marginality ecological criteria altered community composition ecosystem functioning). joint independent assessment is critical avoid common pitfalls where existing outside presumed development automatically considered inferior more traditional settings. We further evaluate differential natural laboratories, discuss strategies conservation management well priorities research. Our new classification provides an important tool improve corals leverage knowledge optimise conservation, restoration rapidly changing ocean.

Including environmental and climatic considerations for sustainable coral reef restoration

PLoS Biology, Journal Year: 2024, Volume and Issue: 22(3), P. e3002542 - e3002542

Published: March 19, 2024

Coral reefs provide ecosystem benefits to millions of people but are threatened by rapid environmental change and ever-increasing human pressures. Restoration is becoming a priority strategy for coral reef conservation, yet implementation remains challenging it increasingly apparent that indirect conservation restoration approaches will not ensure the long-term sustainability reefs. The important role conditions in practice currently undervalued, carrying substantial implications success. Giving paramount importance conditions, particularly during pre-restoration planning phase, has potential bring about considerable improvements innovation. This Essay argues risk may be reduced adopting an environmentally aware perspective gives historical, contemporary, future context decisions. Such approach open up new opportunities with improved have capacity dynamically respond trajectories.

Integrated watershed management solutions for healthy coastal ecosystems and people

Cambridge Prisms Coastal Futures, Journal Year: 2023, Volume and Issue: 1

Published: Jan. 1, 2023

Abstract Tropical coastal ecosystems are in decline worldwide due to an increasing suite of human activities, which threaten the biodiversity and wellbeing that these support. One major drivers is poor water quality from land-based activities. This review summarises evidence impacts ecosystems, particularly coral reefs, sediments, nutrients, chemicals pathogens entering zones through surface groundwater. We also assess how pollutants affect health populations through: (1) enhanced transmission infectious diseases; (2) reduced food availability nutritional deficit fisheries associated with degraded habitat; (3) poisoning consumption contaminated seafood. use this information identify opportunities for holistic approaches integrated watershed management (IWM) target overlapping ill-health downstream people. demonstrate appropriate requires taking a multi-sector, systems approach accounts socio-ecological feedbacks, collaboration required across environmental, agricultural, public health, water, sanitation hygiene sectors, as well land–sea interface. Finally, we provide recommendations key actions IWM can help achieve multiple sustainable development goals both nature people on coasts.

A global synthesis of the current knowledge on the taxonomic and geographic distribution of major coral diseases

Environmental Advances, Journal Year: 2022, Volume and Issue: 8, P. 100231 - 100231

Published: April 26, 2022

Although knowledge on the diseases affecting corals has been accumulating exponentially since 2000s, even more effort is required to summarize and guide further investigation. Here, we used Web of Science database review 226 studies published, between 2000 2020, identify major geographic taxonomic gaps in literature, propose future directions for study coral diseases. We classified according ocean, ecoregion, species, disease types, approach (e.g., observational or experimental), depth. In total, 22 types were reported 165 species. Acropora spp. was most studied taxa with 12 8.2% records. Black band, white plague, syndromes, skeletal eroding, dark spot, yellow band six common diseases, accounting together 76.8% As expected, conducted Caribbean Indo-Pacific (34.0% 28.7%, respectively), but only 44 141 global ecoregions that harbour corals. Observational approaches frequent (75.6% records), while experimental accounted 19.9% mainly done Acropora. The vast majority (∼98%) performed shallow waters (<30 m depth). conclude over past two decades, have assessed a very small fraction few locations around globe, at limited range their depth distribution. While monitoring bleaching mandatory reef ecology conservation, ecoepidemiology deserves space research agenda ecosystems.
