The performance of model-based indices given alternative sampling strategies in a climate-adaptive survey design

Autor: Meaghan D. Bryan, James T. Thorson

Publikováno v: Frontiers in Marine Science, Vol 10 (2023)

Species-distribution shifts are becoming commonplace due to climate-driven change. Difficult decisions to modify survey extent and frequency are often made due to this change and constraining survey budgets. This often leads to spatially and temporal
