Mangroves are among the most carbon-rich ecosystems in world. However, they have experienced widespread loss due to climate change and been reclaimed for coastal cropland aquaculture ponds. Studying impact of on potential distribution carbon benefits mangroves is crucial their conservation restoration. Currently, there limited research China under future scenarios using ensemble models. Furthermore, a relative scarcity studies that apply simulation results restoration protection mangroves. Therefore, based 15 dominant mangrove species, we constructed high-precision species models simulate during current period (1981–2010) predicted three (SSP1-2.6, SSP3-7.0, SSP5-8.5) late 21st century (2071–2100). Our study showed 1) four drivers suitability are: air temperature coldest quarter, sea surface range, isothermality, annual precipitation amount. 2) tend expand northward by 2–2.5 degrees latitude end century. Meanwhile, Spartina alterniflora expected rapidly pose significant competitive threat native species; 3) restoring ponds area, stocks would increase 178.22–296.44 % 170.31–277.13 compared mangroves, blue 242.64–262.70 could provide valuable information China.

Abstract Mangrove‐saltmarsh ecotones are experiencing rapid alterations due to climate change and human activities, however, the ecological morphological implications of these shifts remain largely unknown. This study systematically explores how interspecific interactions herbivory influence dominant wetland species, as well resultant evolution landscape configuration. To achieve this, we develop a new eco‐morphodynamic model that integrates hydrodynamics, sediment transport, bed‐level change, vegetation dynamics. The novelty current lies in newly incorporated modules simulate biotic between mangroves saltmarshes, enabling exploration feedback mangrove‐saltmarsh response tidal flows species interactions. Our results show vertical growth rates coexisting factors determining dominance. When saltmarshes exhibit comparable rates, typically become species. Conversely, if grow more slowly than they unable outcompete saltmarshes. Additionally, can fundamentally alter dominance depending on herbivore food preferences. simulations further underline saltmarsh‐dominated wetlands channel networks extensively rapidly mangrove‐dominated systems. pattern is also observed during invasions, with invading extending networks, while inhibit ongoing network expansion. highlights pivotal roles relative properties driving ecotone development respect at intertidal scale.

Abstract Cross-habitat facilitative processes can enhance seascape restoration outcomes but there is uncertainty around the spatial dependencies of these across habitats. We synthesised influence environmental parameters on six underpinning cross-habitat facilitation and identified linear distances over which they operate between All process types occur at commonly used in demonstrating how harnessing scale-up to meet national international goals.
