Marine Fish Passage—Underappreciated Threats to Connectivity Within the Marine Environment
Marine Ecology, Volume 46, Issue 1, January 2025.ABSTRACT Habitat fragmentation is a major threat to aquatic biodiversity loss. However, much of the focus is on the connectivity of freshwaters, with much less attention given to marine ecosystems. We contend that coastal infrastructure including bridges, causeways, tidal turbines, land infilling and harbours, wharfs, quays, piers and docks have ...

Feedback Analysis of Deformation Modulus for an Extra‐High Arch Dam With Dam Height of 300 m Level
Advances in Civil Engineering, Volume 2025, Issue 1, 2025.Deformation is a critical indicator for safety monitoring of arch dams in operation; comparing measured deformation values with calculated ones is a common approach to assess dam behavior. However, deformation calculated based on design deformation parameters often significantly differs from measured values, especially for extra‐high arch dams; to ...
