Knowledge of coral larval precompetency periods and maximum competency windows is fundamental to understanding population dynamics, informing biogeography connectivity patterns, predicting reef recovery following disturbances. Yet for many species, estimates these early-life history metrics are scarce vary widely. Furthermore, settlement cues taxa not known despite consequences habitat selection. Here we performed a comprehensive experimental time-series investigation behaviour, 25 Indo-Pacific broadcast-spawning species. To investigate the duration precompetency, improve predictions windows, compare responses within amongst completed replicated repeated 24-hour assays that exposed larvae five common cues. Our study revealed in some species begins as early two days post fertilization, but period varies between from about six days, with local retention connectivity. We also found competent settle beyond 70 old display complex temporal challenging assumption gradually wanes over time adding evidence longevity can support genetic long-distance dispersal.

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

Larval propagation and seeding of scleractinian corals for restoration is a rapidly expanding field, with demonstrated applications to assist the recovery declining populations on reefs. The process typically involves collecting coral reproductive material, facilitating in vitro fertilization (IVF), settling outplanting resulting offspring. Optimizing IVF can reduce gamete wastage increase larval yields propagation, therefore improving efficiency this intervention. In study we tested three conditions four Caribbean broadcast-spawning species (i.e., Diploria labyrinthiformis, Colpophyllia natans, Pseudodiploria strigosa, Orbicella faveolata) determine sperm concentration, age, co-incubation time highest success. For each species, exposed eggs from single dam pooled samples sires (1) at concentrations ranging zero 109 cell mL-1, (2) after letting gametes age 2 6 h, (3) period 15 120 min. These experiments revealed longevity least 4 h clear minimum concentration thresholds (>105 106 mL-1) all species.

Abstract Coral reef ecosystems are declining and may not recover under future climate scenarios without intervention. Seeding reefs with corals bred in aquaculture is a promising restoration intervention; however, early coral recruits (spat) vulnerable to overgrowth by benthic algae maximizing their survival essential for the feasibility of large-scale breeding operations. This study investigated optimal light quality intensity spat growth presence algal communities typically used induce larval settlement, but which might also outcompete reduce during grow-out period. Spat were exposed two spectra (blue full spectrum) at four intensities (5–160 µmol m −2 s −1 ) over 12-week post-settlement. Survival was reduced highest nearly 40% compared lowest intensity. Light spectrum only affected 60 —where higher blue light. treatments did affect final size 33% smaller weeks 6 8 due crustose coralline (CCA), most abundant these conditions. Low intensity, on other hand, favored green brown algae, potentially respective physiologies or less competition from algae. These results indicate that low presents several advantages maintaining aquaculture, including significantly affecting growth, as well minimizing husbandry operating expenses.

The restoration of reefs damaged by global and local pressures remains constrained the scale intervention currently feasible. Traditional methods for ex situ sexual propagation corals produce limited materials, typically genetic diversity only sufficient small field trials. development validation new technologies to upscale automate coral is required achieve logistically financially feasible reef at ecologically relevant scales. To address need upscaled production genetically diverse material use in we designed an automated system (the AutoSpawner) harvesting, fertilising washing gametes from tropical broadcast-spawning corals. includes a novel high density dynamic fertilisation process, which enables large numbers fertilised eggs (>7 million per night highly fecund species) without any downstream negative effects on larval quality. functionality quality produced larvae was assessed using multiple species two families (Acroporidae Merulinidae) across range spawning gamete characteristics. We present schematics protocols high-quality this system; demonstrate that time demands, labour costs, associated with traditional manual-based can be reduced up 113-fold AutoSpawner.

Tetrabromopyrrole (TBP) is a readily biosynthesized marine proteobacterial compound that induces coral settlement (attachment and metamorphosis) at concentrations ranging from 50 – 250 ng ml -1 (0.13 0.65 µM).
