… , 2005; MacKenzie and Royle, 2005). We recognized a substantial gap in the literature that
was relevant to a wide range of applications, wherever reliable estimates of occupancy or …

We describe an approach for estimating occupancy rate or the proportion of area occupied
when heterogeneity in detection probability exists as a result of variation in abundance of the …

Spatial replication is a common theme in count surveys of animals. Such surveys often
generate sparse count data from which it is difficult to estimate population size while formally …

A guide to data collection, modeling and inference strategies for biological survey data
using Bayesian and classical statistical methods. This book describes a general and flexible …

The fraction of sampling units in a landscape where a target species is present (occupancy)
is an extensively used concept in ecology. Yet in many applications the species will not …

… Hierarchical Modeling for Ecologists or what we call AHM2 (Kery and Royle, 2021), as
opposed to AHM1, which is what we call Kery and Royle (2016). Here is a brief summary of what …

… Royle and colleagues recognized the need for a synthetic treatment to integrate this work
and place it within a common framework. They wrote Spatial Capture-Recapture in order to fill …

Recently, interest in species distribution modelling has increased following the development
of new methods for the analysis of presence‐only data and the deployment of these …

We develop a model that uses repeated observations of a biological community to estimate
the number and composition of species in the community. Estimators of community-level …

A statistical model is developed for estimating species richness and accumulation by
formulating these community‐level attributes as functions of model‐based estimators of species …
