Eco-engineering approaches offer promising solutions to mitigate these negative impacts, yet remain largely unexplored in the Persian Gulf and Gulf of Oman — regions experiencing both extreme environmental conditions and intensive coastal development. In this study, we assessed the ecological effectiveness of water-retaining structures (rock pools) incorporated into artificial infrastructures at three locations across the Strait of Hormuz and Gulf of Oman. Monthly monitoring of 41 water-retaining structures over a year resulted in the identification of 25 taxa, including gastropods, polychaetes, barnacles, and other intertidal species. Rock pools significantly enhanced species richness and abundance compared to emergent surfaces, with local environmental conditions influencing abundance patterns. Repeated measures ANOVA confirmed significant temporal variation, and PERMANOVA analyses revealed clear differences in community structure among locations. Notably, native species dominated the assemblages, suggesting that eco-engineered structures can promote native biodiversity even under highly stressful conditions. Our findings show that integrating rock pools into coastal infrastructure offers essential microhabitats that buffer environmental stressors, increase species diversity, and contribute to ecosystem resilience.

Here, we systematically reviewed nucleation techniques applied for Neotropical ecosystems restoration. We assessed the focus and spatial distribution of nucleation in response to stakeholder preferences and land-use types. By examining 58 studies, we identified key aspects of the use of nucleation techniques, emphasizing the need for standardized protocols to optimize nucleation strategies for ecosystem recovery. Overall, 12 nucleation techniques were used in Neotropical ecosystem restoration, with artificial perches, topsoil transfer, seedling islets and brushwood being the most frequent. Stakeholders (i.e., researchers, private sector, and governmental agencies) applied various techniques, with researchers more frequently using multiple and combined techniques. Moreover, we observed that stakeholders and land use affect the spatial patterns of nucleation, whereas their focus only responds to land-use types. Nuclei had an average size of 67.58 m<sup>2</sup> ranging from 0.16 m<sup>2</sup> to 1225 m<sup>2</sup>, and techniques focused on flora and fauna showed the greatest spacing between nuclei. Fauna-related techniques were common across all land uses, and the greatest variety of techniques were used in abandoned pastures, former mining sites and protected areas. Although less frequent, using nucleation techniques in combination can contribute to restoration success by addressing multiple objectives.

To better understand the long-term effects of sediment dynamics in the landslide–debris flow disaster chain, this study took the Hanping village landslide–debris flow disaster chain as a case study. By combining field investigations with dynamic simulations, the formation and evolutionary process of the disaster chain was reconstructed. A multisource remote sensing observation scheme integrating unmanned aerial vehicle and satellite remote sensing data was subsequently developed, which further revealed the characteristics of sediment transport and vegetation recovery over a prolonged postdisaster period. Our findings indicate that the formation and evolution of the disaster chain can be divided into four stages: landslide instability, landslide–debris flow transition, debris flow transport, and debris flow deposition. The transformation mechanism of the disaster chain is driven by the blockage failure effect at the bedrock narrows, followed by collision-induced disintegration that reduces particle size and increases water content. The deposits formed during different stages of the dynamic process exhibit significant compositional differences. Multisource remote sensing observations revealed significant spatiotemporal variations, with postdisaster deformation concentrated in channels and depositional regions. The time series deformation results further indicated that surface runoff induced by heavy rainfall exacerbated sediment transport, leading to notable deformation anomalies, with different material compositions exhibiting distinct transport patterns. Postdisaster monitoring revealed a significant increase in vegetation recovery, with an 80 % increase in vegetation area in the two years after the disaster (April 2022–March 2024). The proportion of areas with good recovery increased from 18.52 % to 41.34 % between 2022 and 2023. Moreover, a generalized feedback mechanism model describing sediment transport and vegetation recovery in landslide–debris flow disaster chains was proposed.
