Abstract Under the ongoing global change, a sustained reliance of symbiotic coral species on heterotrophy may support their resistance to climatic stressors. However, much remains unknown about role reproduction, despite its key in persistence populations and connectivity. In this study, we experimentally investigated how heterotrophic feeding parental colonies gorgonian affect larval release survival settlement rates under both optimal heat stress temperatures. A one-week delay absence inputs highlights significant contribution gametogenesis. Moreover, also plays crucial sustaining survival, as low-quality or smaller eggs produced lead significantly higher mortality resulting larvae, independently exposure natural warming Overall, study contributes increase our understanding broader consequences change globally forecasted reduction primary production zooplankton abundance.

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

Earth’s old animals are in decline. Despite this, emerging research is revealing the vital contributions of older individuals to cultural transmission, population dynamics, and ecosystem processes services. Often largest most experienced, valued by humans make important reproduction, information acquisition trophic resistance resilience natural anthropogenic disturbance. These observations contrast with senescence-focused paradigm age that has dominated literature for more than a century yet consistent findings from behavioral ecology life history theory. In this work, we review why global loss can be particularly detrimental long-lived indeterminate growth; those increasing reproductive output age; dependent on migration, sociality, transmission survival. Longevity conservation needed protect ecological roles services provided animals.

Abstract The widespread decline of coral-dominated ecosystems due to human disturbances has highlighted the urgent need for active habitat restoration. Coral restoration using sexually produced individuals instead clonal fragments is essential reduce impacts on donor populations and promote genetic diversity, which vital adaptability environmental changes. However, most coral species, particularly those in temperate deep-water (> 50 m), critical knowledge reproduction larval ecology ex situ sexual propagation lacking. To address this gap, study, we provide first report spawning octocoral Eunicella verrucosa North-East Atlantic describe details development settlement. annual reproductive timing South-West Portugal was determined from samples collected as fisheries bycatch a single population source monitored comparison across distinct durations conditions. species exhibited split-spawning over about one month (mid September – mid October), with 3 major events approximately every 2 weeks. Spawning patterns suggest lunar periodicity but shifted between colonies kept Oocytes were positively buoyant developed into swimming larvae after days. Settlement trials substrates like natural rock, CCA, gorgonian skeleton, showed behaviour testing two weeks post-spawning, settlement activity continuing three months. Fully recruits observed month, sclerite production starting before tentacle development. New continued up months, indicating prolonged competency period. This study provides crucial data efforts ex situ vulnerable species.

Whether restoration actions achieve full ecological recovery is still debated. This particularly controversial in the marine realm, where success of mostly evaluated terms short-term survival transplanted organisms. In view this, we combined population and trait-based approaches to explore long-term effectiveness active a key Mediterranean octocoral. For this purpose, an assemblage with restored Corallium rubrum colonies was monitored over 10 years compared nearby reference site. Our results revealed growth followed by change functional structure (i.e., dominance diversity traits) assemblage. related not only development coral but also arrival and/or increase species different traits. Overall, our findings provide example how long-lived octocorals can be effective tool for recovering high-diverse coralligenous assemblages at decadal timescales.

The frequency and severity of marine heatwaves causing mass mortality events in tropical temperate coral species increases every year, with serious consequences on the stability resilience populations. Although recovery persistence populations after stress is closely related to adult fitness, as well larval survival settlement, much remains unknown about effects thermal early life-history stages species. In present study, reproductive phenology effect increased water temperature (+4°C +6°C above ambient, 20°C) settlement was evaluated for two most representative Mediterranean octocoral (Eunicella singularis Corallium rubrum). Our study shows that behavior more variable than previously reported breeding period occurs over a longer both Thermal did not affect symbiotic E. larvae but drastically reduced non-symbiotic C. rubrum larvae.
