Climate and Land‐Use Change May Reshape the Biogeography of Freshwater Crabs Across China

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
We employed ensemble species distribution models to investigate how climate and land‐use change will impact habitat suitability for two freshwater crab families (Potamidae and Sesarmidae) across China. Temperature emerged as the dominant driver, with cropland and urban land having strong, family‐specific effects on suitability. Future scenarios predict

Biogeomorphic Feedbacks Triggered by Mangrove Degradation at the Seaward Margin Accelerate Persistent Vegetation Decline

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Seaward mangrove edge exhibited significant retreat after extreme disturbances. Rhizophora stylosa exhibited impaired regeneration and root damage in heavily disturbed areas, trait variation primarily responded to elevation and sediment properties, vegetation loss triggered subsidence, creating a positive biogeomorphic feedback loop.

Extensive Pollen Flow and Historical Population Expansions Shaped the Phylogeographic Pattern of Choerospondias axillaris: Evidence From Chloroplast DNA and ITS Sequences

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
MaxEnt‐based predictions reveal dramatic range dynamics of Choerospondias axillaris during Quaternary climate cycles, including northward expansion during the last interglacial, southward contraction into fragmented refugia during the last glacial maximum, and subsequent northward recolonization since the post‐glacial period.
