Hidden impacts of ocean warming and acidification on biological responses of marine animals revealed through meta-analysis

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

Published: April 3, 2024

Conflicting results remain on the impacts of climate change marine organisms, hindering our capacity to predict future state ecosystems. To account for species-specific responses and ambiguous relation most metrics fitness, we develop a meta-analytical approach based deviation from reference values (absolute change) complement meta-analyses directional (relative) changes in responses. Using this approach, evaluate fish invertebrates warming acidification. We find that drivers induce calcification, survival, metabolism, significant deviations twice as many biological responses, including physiology, reproduction, behavior, development. Widespread are detected even under moderate intensity levels acidification, while mostly limited more severe levels. Because such may result ecological shifts impacting ecosystem structures processes, suggest will likely have stronger than those previously predicted alone.

A global meta-analysis of ecological effects from offshore marine artificial structures

Nature Sustainability, Journal Year: 2024, Volume and Issue: 7(4), P. 485 - 495

Published: March 22, 2024

Abstract Marine artificial structures (MAS), including oil and gas installations (O&G) offshore wind farms (OWFs), have a finite operational period. Selecting the most suitable decommissioning options when reaching end-of-life remains challenge, in part because their effects are still largely undetermined. Whether decommissioned could act (sensu ‘function’) as reefs (ARs) provide desired ecological benefits is of particular interest. Here we use meta-analysis approach 531 effect sizes from 109 articles to assess MAS, comparing O&G OWFs shipwrecks ARs, with view inform decommissioning. This synthesis demonstrates that while MAS can bring benefits, important idiosyncrasies exist, differences emerging between types, habitat taxa metrics. Notably, find limited conclusive evidence would significant if ARs. We conclude aimed at repurposing into ARs may not intended benefits.

Ocean acidification drives global reshuffling of ecological communities

Global Change Biology, Journal Year: 2022, Volume and Issue: 28(23), P. 7038 - 7048

Published: Sept. 29, 2022

The paradigm that climate change will alter global marine biodiversity is one of the most widely accepted. Yet, its predictions remain difficult to test because laboratory systems are inadequate at incorporating ecological complexity, and common metrics have varying sensitivity detect change. Here, we for prevalence responses in community-level future (acidification warming) from studies volcanic CO2 vents across four major coastal ecosystems mesocosms.

Temporal dynamics of climate change exposure and opportunities for global marine biodiversity

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

Published: July 15, 2024

Climate change is exposing marine species to unsuitable temperatures while also creating new thermally suitable habitats of varying persistence. However, understanding how these different dynamics will unfold over time remains limited. We use yearly sea surface temperature projections estimate temporal thermal exposure (when exceeds realised species' limits) and opportunity at a previously site becomes suitable) for 21,696 globally until 2100. Thermal opportunities are projected arise earlier accumulate gradually, especially in temperate polar regions. increases later occurs more abruptly, mainly the tropics. Assemblages tend show either high or opportunity, but seldom both. Strong emissions reductions reduce around 100-fold whereas halved. Globally, emerge faster than mid-century when rapidly under scenario. Moreover, across dispersal scenarios, 76%-97% persist These results indicate could be major source biodiversity change, near- mid-term. Our work provides framework predicting where changes occur guide monitoring efforts.

Antarctic macroalgal-associated amphipod assemblages exhibit long-term resistance to ocean acidification

The pH of the world's oceans has decreased since Industrial Revolution due to oceanic uptake increased atmospheric CO2 in a process called ocean acidification. Low been linked negative impacts on calcification, growth, and survival calcifying invertebrates. Along Western Antarctic Peninsula, dominant brown macroalgae often shelter large numbers diverse invertebrate mesograzers, many which are calcified. Mesograzer assemblages this region composed amphipods have key roles macroalgal communities. Understanding acidification is vital for understanding how these communities will be impacted by climate change. To assess long-term may influence different members assemblages, particularly amphipods, associated with alga Desmarestia menziesii were collected from immediate vicinity Palmer Station, Antarctica (S64°46', W64°03') January 2020 maintained under three treatments simulating ambient conditions (approximately 8.1), near-future 2100 (pH 7.7), distant future 7.3) 52 days then enumerated.

Ocean Negative Carbon Emission (ONCE) involves utilizing natural marine chemistry and biology, along with mariculture, to achieve carbon sink goals. Growing awareness of the interplay between aquaculture coastal carbonate system has drawn researchers’ attention amid ring CO 2 concentrations negative impacts on environment. In this study, twelve sites representing different maricultural types were selected, including macroalgae, shellfish, fish, non-farming areas. The environmental factors, dissolved inorganic (DIC), total alkalinity (TA), p , measured monthly during kelp farming periods. Nitrate is a major component nitrogen, NO 3 -N concentration in macroalgal culture zone was lower than others, indicating effective nitrogen removal by macroalgae aquaculture. TA DIC non-farmed areas demonstrated larger variation ranges areas, probably due effects precipitation salinity. Aquaculture activities effectively maintained DIC, cultivation playing an important role stability, potentially resisting acidification. 2sea-air spring slightly negative, suggesting potential.
