Biological monitoring programmes are increasingly relying upon large volumes of citizen‐
science data to improve the scope and spatial coverage of information, challenging the …

A central question to the usefulness of surveys for estimating population trends is whether
the surveys adequately represent the biological communities that are being monitored …

Data collected by volunteers are an important source of information used in species
management decisions, yet concerns are often raised over the quality of such data. Two …

The use of presence/absence data in wildlife management and biological surveys is
widespread. There is a growing interest in quantifying the sources of error associated with …

Monitoring programs serve to track changes in the distribution and abundance of species. A
major problem with most monitoring programs is that species detection is imperfect and …

Occupancy models that account for imperfect detection are often used to monitor anuran and
songbird species occurrence. However, presence—absence data arising from auditory …

Accurate knowledge of species occurrence is fundamental to a wide variety of ecological,
evolutionary and conservation applications. Assessing the presence or absence of species …

The recent surge in the development and application of species occurrence models has
been associated with an acknowledgment among ecologists that species are detected …

An inferential statement is any statement about the parameters, form of the underlying
process or future outcomes. An inferential statement, that provides an approximation to the …

Nondetection of a species at a site does not imply that the species is absent unless the
probability of detection is 1. We propose a model and likelihood‐based method for …
