Hierarchical occupancy/abundance models
Web22 de abr. de 2016 · As hierarchical models, they integrate data across species, permitting composite analyses of communities, species groups and individual species (Russell et al. 2009 ; Zipkin, DeWan & Royle 2009 ). Sharing data across species leads to increased precision in estimates of species richness and species-specific occupancy, particularly … WebFits hierarchical models of animal occurrence and abundance to data collected on species that may be detected imperfectly. Models include single- and multi-season site …
