Conservation Biology, Volume 39, Issue 2, April 2025.Abstract Accelerating rate of human impact and environmental change severely affects marine biodiversity and increases the urgency to implement the Convention on Biological Diversity (CBD) 30×30 plan for conserving 30% of sea areas by 2030. However, area‐based conservation targets are complex to identify in a 3‐dimensional (3D) ocean where deep‐sea ...

Evaluating models of expert judgment to inform assessment of ecosystem viability and collapse
Conservation Biology, Volume 39, Issue 2, April 2025.Abstract Expert judgment underpins assessment of threatened ecosystems. However, experts are often narrowly defined, and variability in their judgments may be substantial. Models built from structured elicitation with large diverse expert panels can contribute to more consistent and transparent decision‐making.
