Limitations of cross‐ and multigenerational plasticity for marine invertebrates faced with global climate change

Global Change Biology, Journal Year: 2019, Volume and Issue: 26(1), P. 80 - 102

Abstract Although cross generation (CGP) and multigenerational (MGP) plasticity have been identified as mechanisms of acclimation to global change, the weight evidence indicates that parental conditioning over generations is not a panacea rescue stress sensitivity in offspring. For many species, there were no benefits conditioning. Even when improved performance was observed, this waned time within or across fitness declined. CGP MGP studies resilient species with tolerant genotypes wild populations selected family lines. Several bivalves possess favourable tolerance phenotypically plastic traits potentially associated genetic adaptation life habitats where they routinely experience temperature and/or acidification stress. These will be important help ‘climate proof’ shellfish ventures. Species are naturally those broad range environmental conditions good candidates provide insights into physiological molecular involved MGP.

As result, present stressors shock‐type exposure at rates much faster than projected scenarios.

Divergent expression of hypoxia response systems under deoxygenation in reef‐forming corals aligns with bleaching susceptibility

Global Change Biology, Journal Year: 2020, Volume and Issue: 27(2), P. 312 - 326

Abstract Exposure of marine life to low oxygen is accelerating worldwide via climate change and localized pollution. Mass coral bleaching mortality have recently occurred where reefs experienced chronic events. However, the mechanistic basis tolerance levels inadequate sustain normal functioning (i.e. hypoxia) whether it contributes susceptibility, remain unknown. We therefore experimentally exposed colonies environmentally resilient Acropora tenuis , a common reef‐building from Great Barrier Reef, deoxygenation–reoxygenation stress that was aligned their natural night–day light cycle. Specifically, treatment involved removing ‘night‐time O 2 buffer’ challenge inherent hypoxia thresholds.

Coral restoration and adaptation in Australia: The first five years

PLoS ONE, Journal Year: 2022, Volume and Issue: 17(11), P. e0273325 - e0273325

While coral reefs in Australia have historically been a showcase of conventional management informed by research, recent declines cover triggered efforts to innovate and integrate intervention restoration actions into frameworks. Here we outline the multi-faceted approaches that developed since 2017, from newly implemented in-water programs, research enhance resilience investigations socio-economic perspectives on goals. We describe projects using gardening, substrate stabilisation, repositioning, macro-algae removal, larval-based techniques. Three areas focus are also presented illustrate breadth Australian restoration, (1) transdisciplinary Reef Restoration Adaptation Program (RRAP), one world’s largest development programs focused reefs, (2) interventions performance under climate change, (3) socio-cultural perspectives.

Synergistic benefits of conserving land-sea ecosystems

Global Ecology and Conservation, Journal Year: 2021, Volume and Issue: 28, P. e01684 - e01684

Published: June 16, 2021

Mangroves, seagrasses, and coral reefs interact in tropical regions throughout the world. These ecosystems exhibit strong synergies, as health of each ecosystem supports functioning adjacent habitats. We present a global spatial analysis mangrove, seagrass, reef communities, identifying where these habitats co-occur. While only an estimated 18% interaction zones are covered by protected areas, boundaries between mangroves, represent areas high conservation efficiency, benefits amplify synergistically land-sea jointly managed. discuss four types efficiencies coastal ecosystems: (1) increased resistance to disturbance through inter-ecosystem feedbacks, (2) biodiversity within small geographic (3) habitat portfolio effects giving rise climate refugia, (4) synergistic services, building one service inherently increases others.

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.

Heterotrophy in marine animal forests in an era of climate change

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Journal Year: 2024, Volume and Issue: 99(3), P. 965 - 978

Published: Jan. 29, 2024

Marine animal forests (MAFs) are benthic ecosystems characterised by biogenic three-dimensional structures formed suspension feeders such as corals, gorgonians, sponges and bivalves. They comprise highly diversified communities among the most productive in world's oceans. However, MAFs decline due to global local stressors that threaten survival growth of their foundational species associated biodiversity. Innovative scalable interventions needed address degradation increase resilience under change. Surprisingly, few studies have considered trophic interactions heterotrophic feeding MAF an integral component conservation. Yet, important for nutrient cycling, energy flow within food web, biodiversity, carbon sequestration, stability. This comprehensive review describes at all levels ecological organisation tropical, temperate, cold-water MAFs. It examines strengths weaknesses available tools estimating capacities then discusses threats climate change poses processes. Finally, it presents strategies improving heterotrophy, which can help maintain health
