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.

Quantifying coral reef biodiversity is challenging for cryptofauna and organisms in early life stages. We demonstrate the utility of eDNA metabarcoding as a tool comprehensively evaluating invertebrate communities on complex 3D structures reformation, role these play provisioning habitat organisms. design printing were used to create 18 tiles, which form artificial structures. was collected from scraping tile surfaces organismal biomass seawater samples around reefs Gulf Eilat/Aqaba, Red Sea.

Pathways to sustain atolls under rising sea levels through land claim and island raising

Environmental Research Climate, Journal Year: 2023, Volume and Issue: 2(1), P. 015005 - 015005

Published: Feb. 16, 2023

Abstract Low-lying atoll nations (e.g. the Maldives, Kiribati, Tuvalu, Marshall Islands) are highly vulnerable to climate change, especially sea-level rise (SLR). Stringent change mitigation will slow but not stop SLR, which continue for centuries, mandating additional long-term adaptation. At same time, urbanisation is concentrating population in a few centres, around capital islands creates pressure as most ‘land-poor’. This paper demonstrates how structural adaptation using land claim and island raising can be utilised within an pathway approach sustain enough area above rising sea levels satisfy societal economic needs over multiple centuries. illustrated its environs (Greater Malé).

Community-managed coral reef restoration in southern Kenya initiates reef recovery using various artificial reef designs

Monitoring of reef restoration efforts and artificial reefs (ARs) has typically been limited to coral fragment survival, hampering evaluation broader objectives such as ecosystem recovery. This study aimed determine what extent AR design influences the ecological recovery restored by monitoring outplanted fragments, benthic cover, recruitment fish invertebrate communities for two years. Four designs (16 m 2 ), unrestored controls natural patches reference (n = 10) were established in Mkwiro, Kenya. ARs consisted either concrete disks with bottles, layered disks, metal cages or a combination thereof. A mixture 18 branching species (mainly Acropora spp.) was on at density 7 corals -2 . After years, 60% all fragments had survived, already resulting cover most comparable (though -dominated) patches.

Restoration ecology meets design-engineering: Mimicking emergent traits to restore feedback-driven ecosystems

The Science of The Total Environment, Journal Year: 2023, Volume and Issue: 902, P. 166460 - 166460

Published: Aug. 21, 2023

Ecosystems shaped by habitat-modifying organisms such as reefs, vegetated coastal systems and peatlands, provide valuable ecosystem services, carbon storage protection. However, they are declining worldwide. Ecosystem restoration is a key tool for mitigating these losses but has proven failure-prone, because stability often hinges on self-facilitation generated emergent traits from habitat modifiers. Emergent not expressed the single individual, emerge at level of an aggregation: minimum patch-size or density-threshold must be exceeded to generate self-facilitation. Self-facilitation been successfully harnessed clumping transplanted organisms, requires large amounts often-limiting costly donor material. Recent advancements highlight that kickstarting mimicking can similarly increase success. In this perspective, we framework combining expertise ecologists, engineers industrial product designers transition trial-and-error trait design-based, cost-efficient approaches support large-scale restoration.
