- Abstract - The spAbundance R package provides a user-friendly platform to fit spatially explicit single-species and multi-species hierarchical distance sampling models, N-mixture models, and generalized linear mixed models using a Bayesian approach. We provide three vignettes and three case studies that highlight spAbundance functionality. - - We used spatially explicit multi-species distance sampling models to estimate density of 16 bird species in Florida, USA, an N-mixture model to estimate black-throated blue warbler (Setophaga caerulescens) abundance in New Hampshire, USA, and a spatial linear mixed model to estimate forest above-ground biomass across the continental USA. spAbundance provides a user-friendly, formula-based interface to fit a variety of univariate and multivariate spatially explicit abundance models. The package serves as a useful tool for ecologists and conservation practitioners to generate improved inference and predictions on the spatial drivers of abundance in populations and communities. + Abstract - The spAbundance R package provides a user-friendly platform to fit spatially explicit single-species and multi-species hierarchical distance sampling models, N-mixture models, and generalized linear mixed models using a Bayesian approach.
