Abundance of rare and elusive species: Empirical investigation of closed versus spatially explicit capture–recapture models with lynx as a case study
Abstract Effective conservation and management require reliable monitoring methods and estimates of abundance to prioritize human and financial investments. Camera trapping is a non‐invasive sampling method allowing the use of capture–recapture (CR) models to estimate abundance while accounting for...
