Abstract Coral propagation- and planting-based reef restoration practices are accelerating globally, yet short-term “success” continues to be measured as broad metrics of coral survival growth, even though goals often centred on recovering ecosystem service values. As such, how activities may impact healthy functioning remains uncertain. For example, trade-offs in resource acquisition partitioning that potentially regulate growth vs yield very different outcomes towards factors governing biogeochemical cycles. Here we considered a proof-of-concept “multi-trait” approach capture broader range functional traits reflect the expression for key species (Acropora cf. hyacinthus) — impacted by recent mass bleaching events propagated Great Barrier Reef (GBR), Australia. We examined diverse array bio-physical, bio-chemical, skeletal (n = 91 traits) wild (donor) colonies their nursery-derived fragments from 12-month period (Opal Reef, northern GBR). Nursery corals grew 20-25 times faster than donor (wild) colonies, but both exhibited similar survivorship. Faster within nurseries was accompanied more pigmented (darker-coloured with symbionts), higher photosynthesis, respiration, calcification rates. However, despite these metabolic changes, properties nursery (carbohydrates, lipids, proteins, elemental stoichiometry, properties) remained largely same after 12 months, suggesting bio-energetic value trophic transfer well structural rigour unaltered propagation. Thus, enables informed evaluation propagation values, highlighting immense importance this knowledge choosing individuals restoration. Our example provides confidence practitioners attributes native retained through an intermediate phase can accelerate biomass gains.

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.

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

One approach to improve long-term coral restoration success utilizes naturally stress-tolerant corals from the wild. While focus has primarily been on thermal stress, low oxygen is a growing threat reefs and efforts should also consider hypoxia tolerance. Here we determine if Siderastrea siderea Agaricia tenuifolia populations reef with historical record of exhibit evidence local adaptation hypoxic events, compared reference reef. We employed laboratory-based reciprocal transplant experiment mimicking severe 14-night event monitored bleaching responses, photo-physiology, metabolic rates, survival all four during, for two weeks following event. In both species, found either fully persisted or recovered within 3 days contrast, conspecific naïve well-oxygenated experienced death. This showcases vulnerability exposed but suggests that locally adapted survive episodic hypoxia. Other past may be home signatures useful efforts.
