Coral reef ecosystems have suffered an unprecedented loss of habitat-forming hard corals in recent decades. While marine conservation has historically focused on passive habitat protection, demand for and interest active restoration been growing However, a disconnect between coral practitioners, managers scientists resulted disjointed field where it is difficult to gain overview existing knowledge. To address this, we aimed synthesise the available knowledge comprehensive global review methods, incorporating data from peer-reviewed scientific literature, complemented with grey literature through survey practitioners. We found that case studies are dominated by short-term projects, 60% all projects reporting less than 18 months monitoring restored sites. Similarly, most relatively small spatial scale, median size area 100 m2. A diverse range species represented dataset, 229 different 72 genera. Overall, primarily fast-growing branching (59% studies), report survival 60 70%. date, young plagued similar 'growing pains' as ecological other ecosystems. These include 1) lack clear achievable objectives, 2) appropriate standardised and, 3) poorly designed relation stated objectives. Mitigating these will be crucial successfully scale up retain public trust tool resilience based management. Finally, while practitioners developed effective methods grow at scales, critical not view replacement meaningful action climate change.

Severe Continental-Scale Impacts of Climate Change Are Happening Now: Extreme Climate Events Impact Marine Habitat Forming Communities Along 45% of Australia’s Coast

Frontiers in Marine Science, Journal Year: 2019, Volume and Issue: 6

Published: July 24, 2019

Recent increases in the frequency of Extreme Climate Events (ECEs) such as heatwaves and floods have been attributed to climate change, could pronounced ecosystem evolutionary impacts because they provide little opportunity for organisms acclimate or adapt. Here we synthesize information on a series ECEs Australia from 2011-2017 that led well-documented, abrupt extensive mortality key marine habitat-forming – corals, kelps, seagrasses mangroves along nearly more than 45% continental coastline Australia. Coral bleaching occurred across much northern due affecting different regions 2011, 2013, 2016 2017, while seagrass was impacted by anomalously high rainfall events 2011 both east west tropical coasts. A heatwave off western during La Niña extended into temperate subtropical regions, causing widespread kelp forests communities at their distribution limits. Mangrove experienced El Niño coastal areas north-western severe water stress driven drought low mean sea levels. This reflects variety heatwaves, intense storms, drought. Their repeated occurrence wide extent are consistent with projections increased intensity ECEs, broad implications elsewhere similar trends predicted globally. The unprecedented nature these ECE has likely produced substantial ecosystem-wide repercussions. Predictions models suggest taxa will long-term some cases irreversible consequences, especially if continue become frequent severe. ecological changes caused greater slower warming leads gradual reorganisation possible evolution adaptation. an emerging threat ecosystems, require better seasonal prediction mitigation strategies.

Sounding the Call for a Global Library of Underwater Biological Sounds

Frontiers in Ecology and Evolution, Journal Year: 2022, Volume and Issue: 10

Published: Feb. 8, 2022

Aquatic environments encompass the world’s most extensive habitats, rich with sounds produced by a diversity of animals. Passive acoustic monitoring (PAM) is an increasingly accessible remote sensing technology that uses hydrophones to listen underwater world and represents unprecedented, non-invasive method monitor environments. This information can assist in delineation biologically important areas via detection sound-producing species or characterization ecosystem type condition, inferred from properties local soundscape. At time when worldwide biodiversity significant decline soundscapes are being altered as result anthropogenic impacts, there need document, quantify, understand biotic sound sources–potentially before they disappear. A step toward these goals development web-based, open-access platform provides: (1) reference library known unknown biological sources (by integrating expanding existing libraries around world); (2) data repository portal for annotated unannotated audio recordings single soundscapes; (3) training artificial intelligence algorithms signal classification; (4) citizen science-based application public users. Although individually, resources often met on regional taxa-specific scales, many not sustained and, collectively, enduring global database integrated has been realized. We discuss benefits such program provide, previous calls data-sharing libraries, challenges be overcome bring together bio- ecoacousticians, bioinformaticians, propagation experts, web engineers, processing specialists (e.g., intelligence) necessary support funding build sustainable scalable could address needs all contributors stakeholders into future.

Systematic review of the uncertainty of coral reef futures under climate change

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: March 12, 2024

Abstract Climate change impact syntheses, such as those by the Intergovernmental Panel on Change, consistently assert that limiting global warming to 1.5 °C is unlikely safeguard most of world’s coral reefs. This prognosis primarily based a small subset available models apply similar ‘excess heat’ threshold methodologies. Our systematic review 79 articles projecting reef responses climate revealed five main methods. ‘Excess constituted one third (32%) all studies but attracted disproportionate share (68%) citations in field. Most methods relied deterministic cause-and-effect rules rather than probabilistic relationships, impeding field’s ability estimate uncertainty. To synthesize projections, we aimed identify with comparable outputs. However, divergent choices model outputs and scenarios limited analysis fraction studies. We found substantial discrepancies projected impacts, indicating serving basis for syntheses may project more severe consequences other Drawing insights from fields, propose incorporate uncertainty into modeling approaches multi-model ensemble approach generating projections futures.
