Climate-driven range shift reveals systemic ecological disruption: Atlantic mangrove fiddler crab expands into temperate salt marshes

The study combines long‑term temperature records, species distribution modeling, and carbon flux measurements to quantify the crab's range shift and its ecosystem consequences. Peer‑reviewed data demonstrate that the newcomer alters sediment stability, predator‑prey dynamics, and reduces the marsh's carbon sequestration efficiency. The rigorous methodology provides a credible foundation for systemic climate‑impact assessments.
The northward expansion of the Atlantic mangrove fiddler crab illustrates a systemic ecological re‑ordering that intertwines Indigenous observations, historical climate cycles, and cutting‑edge scientific modeling.
Cross‑cultural comparisons reveal that traditional mixed‑use stewardship may offer adaptable templates for the emerging hybrid habitats, while artistic and trickster narratives expose the paradoxes hidden in conventional discourse. Marginalised coastal communities, whose livelihoods are directly threatened, provide essential on‑the‑ground insight that must inform future scenario planning. Together, these dimensions call for integrated, community‑driven, and dynamically accounted solutions that address both ecological function and social equity.
