In mountain ecosystems, the persistence of species increasingly depends on the maintenance of functional connectivity under the dual pressures of climate and land‐use change. “Sky island” species such as the mountain hare ( Lepus timidus ) are particularly vulnerable, being restricted to high‐altitude cold‐climate habitats. Meanwhile, generalist and expanding species like the European hare ( L. europaeus ) may further threaten...

Assessing the impact of global changes and protection effectiveness is a key step in monitoring marine fishes. Most traditional census methods are demanding or destructive. Nondisturbing and nonlethal approaches based on video and environmental DNA are alternatives to underwater visual census or fishing. However, their ability to detect multiple biodiversity factors beyond traditional taxonomic diversity is still unknown. For...
